Judgment SINHA ( 1 ) THESE appeals on certificates granted under Art. 132 of the Constitution by the High Court of Judicature in Assam and writ Petition under Art. 32 of the Constitution impgun the constitutionality of the Assam Taxation (on Goods Carried by Roads or Inland Waterways) Act, (Assam Act 13 of 1954) which hereinafter will be referred to as the Act. The appellants moved the High Court under Art. 226 of the Constitution challenging the validity of the Act. The High Court by its judgment and order dated 6/06/1955, dismissed the writ petitions. Thereupon, the appellants obtained the certificates that the cases involved substantial questions of law as to the interpretation of the Constitution. The petitions under Art. 32 of the Constitution were moved in this Court for the same purpose of challenging the vires of the Act. The appellants and the petitioners will, in the course of this judgment, be referred to, for the sake of convenience, as the appellants. The State of Assam, the Commissioner of Taxes, appointed under S. 6 of the Act, and the Superintendent of Taxes are the respondents to the appeals and the writ petitions. ( 2 ) IT appears that the appellants are growers of tea in West Bengal or in Assam and carry their tea to the market in Calcutta from where the tea is sold for consumption in the country or is exported for sale out of the country. The sale of tea inside Assam bears a very small proportion to the tea produced and manufactured by the appellants. Thus the bulk of tea produced and manufactured is carried out of Assam, either for internal consumption in India or for export abroad. Besides the tea carried by rail, a large quantity of tea is carried by road or by inland waterways from Assam to Bengal and in some of these cases, from one part of West Bengal to another part of the same State through inland waterways, only a few miles of which pass through the territory of the State of Assam. The Assam Legislature passed the act which received the assent of the Governor of Assam on 9/04/1954, the came into force on and from 1/06/1954. The purpose of the Act is to levy taxes on certain goods carried by road or inland water-ways in the State of Assam. The Assam Legislature passed the act which received the assent of the Governor of Assam on 9/04/1954, the came into force on and from 1/06/1954. The purpose of the Act is to levy taxes on certain goods carried by road or inland water-ways in the State of Assam. On 30/06/1954, the second respondent, the Commissioner of Taxes, Assam, in exercise of the powers conferred upon him by sub-s. (3) of S. 7 of the Act, published a notification in the Assam Government Gazette bearing date 21/06/1954, by which he notified for general information that the return under the aforesaid Act and the rules made thereunder for the period commencing 1/06/1954 , should be furnished by 30/10/1954. The said notification also demanded the furnishing of quarterly returns before 30/01/1955 and 30/04/1955, for the quarters ending 31/12/1954 and 31/03/1955, respectively. The appellants in some of the cases, in pursuance of demand notices, submitted returns to the third respondent, the Superintendent of Taxes, in the prescribed form in respect of tea despatched and carried up to 30/09/1954, under protest. They also paid the tax demanded under protest. The appellants moved the High Court of Judicature in Assam under Art. 226 of the Constitution challenging the validity of the said Act and praying for the issue of a writ of mandamus directing the respondents to forbear from giving effect to be provisions of the Act and the notification issued under the Act and/or a writ of prohibition or any other appropriate writ restraining them from taking steps under the provisions of the Act. The appellants challenged the validity of the Act mainly on the grounds that (1) the Act, rules and the notifications under the Act were ultra vires the Constitution, because the Act was repugnant to the provisions of Art. 301 of the Constitution as the tax on carriage of tea through the State of Assam had the effect of interfering with the freedom of trade, commerce and intercourse; (2) that tea being a controlled industry under the provisions of the Tea Act, 29 of 1953, the Union Government alone had the power to regulate the manufacture, production, distribution or transport of tea and the jurisdiction of the Assam Legislature was thus completely ousted; (3) that the tax under the Act was nothing but a duty of excise, in substance, though not in form, and was thus an encroachment on the Central legislative field within the meaning of entry 84 of the Union List. The impugned Act was also challenged on the ground that it was discriminatory and thus void under Art. 14 of the Constitution. The competence of the Assam Legislature to legislate on the subject was also questioned. ( 3 ) THE respondents opposed those petitions under Art. 226 of the Constitution in the High Court. It was denied by the State that the Act or the rules made thereunder or the notifications issued thereunder were ultra vires the Constitution or that the Act contravened the provisions of Art. 301 of the Constitution or that it was an encroachment on the sphere of the Union Legislature or was in any way in conflict with the provisions of the Tea Act 29 of 1953. The case of the respondents was that the Act was in pith and substance, a legislation to levy tax on certain classes and types of goods carried by road or inland waterways, strictly within entry No. 56 of the State List. It was also asserted that the Act was within the legislative competence of the Assam Legislature and was not within the terms of the prohibition contained in Art. 301 of the Constitution. ( 4 ) THESE petitions were heard by a Special Bench of the Assam High Court which, by its judgment and order dated 6/06/1955, dismissed them holding that the Act was not unconstitutional. ( 4 ) THESE petitions were heard by a Special Bench of the Assam High Court which, by its judgment and order dated 6/06/1955, dismissed them holding that the Act was not unconstitutional. Two separate, but concurring judgments, were delivered by Sarjoo Prosad, C. J. , and Ram Labhaya, J. The learned Chief Justice, in the course of his judgment, held that the Act contemplated imposition of a tax on transport or carriage of goods within the meaning of entry 56 of List II and did not amount to interference with the freedom of trade and commerce within the meaning of Art. 301 of the Constitution; that the pith and substance of the impugned Act was that it was a taxing legislation which was not directly concerned with trade and commerce, though it might indirectly entrench on the field of trade and commerce and that Art. 301 was not directly concerned with taxing laws. He also held that the impost levied by the Act was not in the nature of an excise duty and that there was no substance in the contention that it encroached upon entry 84 of the Union List I. It was also held that the impugned Act did not, in any way, come in conflict with the control of the tea industry introduced by the Central Legislation, namely, the Tea Act 29 of 1953. ( 5 ) RAM Labhaya, J. examined the provisions of the impugned Act in great detail and came to the conclusion that the element of carriage was expressly made a condition of liability to tax under the impugned Act and it was, therefore, distinguishable from a duty of excise and came directly under entry 56 of List II. On the crucial question arising in this case, his conclusion was that taxation per se has not the effect of abridging or curtailing the freedom contemplated by Art. 301; that Arts. On the crucial question arising in this case, his conclusion was that taxation per se has not the effect of abridging or curtailing the freedom contemplated by Art. 301; that Arts. 302 and 304 restrict the powers of Parliament and the State Legislatures in the matter of legislation under entries 42 of List I, 26 of List II and 33 of List III and that restrictions properly so called on the movement of goods and traffic must find their justification from the provisions of Part 13 of the Constitution; that the impugned Act made provision for taxation which did not directly impinge upon the freedom of trade, commerce and intercourse within the meaning of Art. 301. His view also was that in some cases taxation may have the effect of placing restrictions on movement of goods and traffic, and if it has that effect, it comes within the mischief of Art. 301. In the result, his conclusion was that the impugned Act in its pith and substance fell within the ambit of entry 56 of List II. He also examined the terms of the Union legislation, Tea Act No. 29 of 1953, and came to the conclusion that the impugned Act did not trespass upon the field of the controlled industry of tea. His conclusion with reference to the argument of discrimination based on Art. 14 was that there was no proof forthcoming of any real discrimination between persons and things. With these conclusions Deka, J. , the third Judge, entirely agreed. From the judgment of the High Court the appellants have come up in appeal on certificates granted by the High Court. The two petitions under Art. 32 of the Constitution were filed on behalf of two other producers of tea. They raise the same questions as arise for determination in the three appeals from the decision of the Assam High Court. They have all be heard together and will be dealt with by a common judgment. ( 6 ) MR. The two petitions under Art. 32 of the Constitution were filed on behalf of two other producers of tea. They raise the same questions as arise for determination in the three appeals from the decision of the Assam High Court. They have all be heard together and will be dealt with by a common judgment. ( 6 ) MR. Chatterjee, on behalf of the appellants, contended that the impugned Act imposed fetters on the free flow of trade and commerce in respect of tea and jute, the two commodities dealt with by the Act, and, therefore, contravened the provisions of Art. 301 of the Constitution; that the legislation was beyond the legislative competence of the Assam Legislature and was not authorised by entry 56 in List II; that the tea industry was a controlled industry as declared by Parliament and directly came under entry 52 of List I; that it was a colourable piece of legislation which, in its true effect, was a levy of a duty of excise which could only be done by the Union Legislature, and finally, that it contravened Art. 14 of the Constitution. ( 7 ) THE learned Attorney General on behalf of the State of Assam as also of the Union contended, on the other hand, that taxation simpliciter was not within the terms of Art. 301. Taxation as such is not a restriction within the meaning of Part 13. It is an attribute of sovereignty, which is not justiciable. The power to tax is a peculiar legislative function with which the courts are not directly concerned and that, therefore, the freedom contemplated by Art. 301 does not mean freedom from taxation and that taxation is not included within the connotation of the term. "restriction in the context of Part 13 meant legislation which had the effect of impeding the free flow of goods and traffic by erection of tariff walls, for example. A tariff wall, in erected by a Legislature, may, be justiciable, but not legislation simple imposing a tax for purposes of revenue. He further contended that Part XII of the Constitution is a self-contained part dealing with finance etc. , even as Part 13 is a self-contained part dealing with trade, commerce and intercourse within the territory of India. A tariff wall, in erected by a Legislature, may, be justiciable, but not legislation simple imposing a tax for purposes of revenue. He further contended that Part XII of the Constitution is a self-contained part dealing with finance etc. , even as Part 13 is a self-contained part dealing with trade, commerce and intercourse within the territory of India. He emphasised that the American and Australian decisions are no guide to the decision of the points in controversy in the present case as the framework of their respective constitutions was entirely different from the Indian Constitution. Particularly, the Australian Constitution did not contain anything corresponding to Parts III and XII of our Constitution. According to his contention "freedom in Part XII meant freedom from discriminatory taxation and freedom from trade barriers. The Advocate-General of the several States who appeared in this case supported the view point stressed by the learned Attorney-General. ( 8 ) THE most important question that falls to be determined in this batch of cases is whether the impugned Act infringes the provisions of Part 13 of the Constitution, with particular reference to Art. 301. Part 13 is headed "trade, Commerce and Intercourse within the Territory of India. Article 301, which is the opening Article in this Part is in very general terms, which are as under:- "subject to the other provisions of this Part, trade, commerce and intercourse throughout the territory of India shall be free. IT is clear that this Part is not subject to the other provisions of the Constitution and the generality of the words used in Art. 301 is cut down only by the provisions of the other Articles of this Part ending with Art. 307. It has not been and it could not be contended that the generality of the expressions used in Art. 301 admit of any exceptions or explanations not occurring in this Part itself nor has it been contended that trade, commerce and intercourse are subject to any other fetters. All parties are agreed that trade, commerce and intercourse throughout the territory of India have been emphatically declared by the Constitution to be free, but there is a wide divergence of views on the answer to the question "free from what? All parties are agreed that trade, commerce and intercourse throughout the territory of India have been emphatically declared by the Constitution to be free, but there is a wide divergence of views on the answer to the question "free from what? It has been contended on behalf of the appellants that the answer to this question must be that trade, commerce and intercourse throughout India, shall be free from everything including taxation. On the other hand, the contention on behalf of the Union Government and the State Governments is that the freedom envisaged by Art. 301 does not include immunity from taxation and that freedom means that there shall be no trade barriers or tariff walls shutting out commodities, traffic and intercourse between individuals, and no shutting in. ( 9 ) IN order fully to appreciate the implications of the provisions of Part 13 of the Constitution, it is necessary to bear in mind the history and background of those provisions. The Constitution Act of 1935 (Government of India Act, 26 Geo. 5, Ch. 2) which envisaged a federal constitution for the whole of India, including what was then Indian India in contradistinction to British India, which could not be fully implemented and which also introduced full provincial autonomy enacted S. 297 prohibiting certain restrictions on internal trade in these terms:- "297.- (1) No Provincial Legislature or Government shall - (A) by virtue of the entry in the Provincial Legislative List relating to trade and commerce within the Province, or the entry in that list relating to the production, supply, and distribution of commodities, have power to pass any law or take any executive action prohibiting or restricting the entry into, or export from the Province of goods of any class or description; or (B) by virtue of anything in this Act have power to impose any tax, cess, toll or due which, as between goods manufactured or produced in the Province and similar goods not so manufactured or produced, discriminates in favour of the former, or which, in the case of goods manufactured or produced outside the Province, discriminates between goods manufactured or produced in one locality and similar goods manufactured or produced in another locality. 2. Any law passed in contravention of this section shall, to the extent of the contravention, be invalid. 2. Any law passed in contravention of this section shall, to the extent of the contravention, be invalid. ( 10 ) IT will be noticed that the prohibition contained in the section quoted above applied only to Provincial Governments and Provincial Legislatures with reference to entries in the Provincial Legislative List relating to trade and commerce within the Province and to production, supply and distribution of commodities. That section dealt with prohibitions or restrictions in respect of import into or export from a Province, of goods generally. It also dealt with the power to impose taxes etc. and prohibited discrimination against goods manufactured or produced out side a Province or goods produced in different localities. Part 13 of the Constitution has introduced all those prohibitions, not only in respect of State Legislatures but of Parliament also. In other words, Part 13 enlarges the scope of the inhibitions and lays down the limits within which the Union Parliament or a State Legislature may legislate with reference to trade, commerce and intercourse inter-State, intra-State and throughout the territory of India. ( 11 ) IN this connection it has got to be remembered that before the commencement of the Constitution about two-thirds of India was directly under British rule and was called british India and the remaining about one-third was being directly ruled by the Princes and was known as native States. There were a large number of them with varying degrees of sovereignty vested in them. Those rulers had, broadly speaking, the trappings of a Sovereign State with power to impose taxes and to regulate the flow of trade, commerce and intercourse. It is a notorious fact that many of them had erected trade barriers seriously impeding the free flow of trade, commerce and intercourse not only shutting out but also shutting in commodities meant for mass consumption. Between the years 1947 and 1950 almost all the Indian States entered into engagements with the Government of India and ultimately merged their individualities into India as one political unit, with the result that what was called British India, broadly speaking, became, under the Constitution, Part A States, and subject to certain exceptions not relevant to our purpose, the Native States became Part B States. We also know that before the Constitution introduced the categories of Part A States, Part B States and Part C States (excluding Part D relating to other territories), Part B States themselves, before their being constituted into so many units, contained many small States, which formed themselves into Unions of a number of States, and had such trade barriers and custom posts, even inter se. But even after the merger, the Constitution had to take notice of the existence of trade barriers and therefore had to make transitional provisions with the ultimate objective of abolishing them all. Most of those Native States, big or small, had their own taxes, cesses, tolls and other imposts and duties meant not only for raising revenue, but also as trade barriers and tariff walls. It was in the background of those facts and circumstances that the Constitution by Art. 301 provided for the abolition of all those trade barriers and tariff walls. When for the first time in the history of India the entire territory within the geographical boundaries of India, minus what became Pakistan, was knit into one political unit, it was necessary to abolish all those trade barriers and customs posts in the interest of national solidarity, economic and cultural unity as also of freedom of trade, commerce and intercourse. ( 12 ) IT is in the background of these facts and circumstances that we have to determine the ambit of the freedom contemplated by Art. 301. That Article envisages freedom of trade and commerce with reference to different parts of India as also freedom of movement of individuals in relation to their trade and other activities. Hence, Art. 301 has reference not only to trade and commerce, as ordinarily understood in common parlance, but also in relation to individuals who have to move with their goods and commodities throughout the length and breadth of the country. Movement of traffic in goods and commodities as also of persons can be by railway or airways, by road or by inland waterways, etc. , etc. Carriage of goods and passengers by railway, by sea or by air or by national waterways in covered by entry 30 of List I and taxes on railway fares and freights and terminal taxes on goods or passengers carried by railway, sea or air come under the purview of entry 89 in the same List. , etc. Carriage of goods and passengers by railway, by sea or by air or by national waterways in covered by entry 30 of List I and taxes on railway fares and freights and terminal taxes on goods or passengers carried by railway, sea or air come under the purview of entry 89 in the same List. On the other hand, taxes on goods and passengers carried by road or inland waterways come under entry 56 of List II (State List ). It will thus be seen that the Constitution-makers contemplated taxes on goods and passengers to be imposed by the Parliament on journeys covered by railway or by sea or by air; and by State Legislatures on journeys by road or inland waterways. The power to tax is inherent in sovereignty. The sovereign State, in some cases the Union, in other cases the State, has the inherent power to impose taxes in order to raise revenue for purposes of State. Such a sovereign power ordinarily is not justiciable, simply because the State in its legislative department has to determine the policy and incidence of taxation. It is the State which determines, through the Legislature, what taxes to impose, on whom and to what extent. The judicial department of the State is not expected to deal with such matters, because it is not for the courts to determine the policy and incidence of taxation. This power of the State to raise finances for Government purposes has been dealt with by Part XII of the Constitution, which contains the total prohibition of levy or collection of tax, except by authority of law (Art. 265 ). This Part also deals with the distribution of revenue between the Union and the States. It does not clearly demarcate the taxing authority as between the Union and the States and therefore had to indicate in great detail what taxes shall be levied for the benefit of the Union or for the benefit of the States and what taxes may be levied and collected by the Union for the benefit of the States and what taxes may be levied and collected by the Union for the benefit of the States and the principle according to which those revenues have to be distributed amongst the constituent States of the Union. In short, Part XII is a self-contained series of provisions relating to the finances of the Union and of the States and their inter-relation and adjustments (ignoring the provisions in Ch. 2 of that Part relating to borrowing and Ch. 3 relating to property, contracts, etc. ). Like Part 13, Part XII also is not expressed to be subject to the other provisions of the Constitution. Hence, both Parts XII and 13 are meant to be self-contained in their respective fields. It cannot, therefore, be said that the one is subject to the other. But it has been argued on behalf of the appellants that the provisions of Art. 304 indicate that taxation is within the purview of the overriding provisions, as they have been characterised, of Art. 301. But a close examination of the provisions of Art. 304 would show that it is divided into two parts, viz. , (1) dealing with imposition of discriminatory taxes by a State Legislature; and (2) relating to imposition of reasonable restrictions, thus showing that imposition of taxes, discriminatory or otherwise, is a class apart from imposition of reasonable restrictions on freedom of trade, commerce and intercourse. The second part of Art. 304 dealing with imposition of reasonable restrictions on freedom of trade, commerce and intercourse by a State Legislature is on a line with the imposition by Parliament of such restrictions between one State and another or within any part of the territory of India in public interest, contained in Art. 302. The provisions of Art. 303 further make it clear that the giving of preference to one State over another or discrimination between one State and another are clearly within the purview of Part 13, that is to say, they are calculated to impede the freedom of trade, commerce and intercourse. There is a prohibition against Parliament as also against the Legislature of a State making any law giving preference to one State over another or making or authorising the making of any discrimination between one State and another. But the most significant words in connection with giving preference or making discrimination as envisaged in Art 303 are with reference to "any entry relating to trade and commerce in any of the Lists in the Seventh Schedule, that is to say, entry 42 in List I, entry 26 in List II and entry 33 in List III of the Seventh Schedule. Hence, any legislation under those entries which has the effect of directly interfering with trade, commerce and intercourse being free throughout the territory of India has to be struck down as infringing the provisions of Art. 301. But in this matter also the Constitution-makers had before them situations of emergency, say for example, created by drought or overflooding resulting in scarcity of commodities like food-grains, etc. In such a situation, Parliament has been armed with the power to grant preference to one State over another or to make a discrimination as between two or more States if the Law dealing with such a situation declares that it is necessary to do so in order to deal with an emergency like the one referred to above. In this connection it may not be emphasised that Art. 303 has not been very accurately worded inasmuch as the non obstinate clause, with which the Article opens, has reference only to Art. 302, which empowers Parliament to impose by law restrictions on the freedom of trade, commerce or intercourse, inter-State or intra-State, in public interest. But the non obstante clause is immediately followed by reference not only to Parliament but also to the Legislature of a State which are armed with the power of giving preference or making discrimination as aforesaid in respect of the entries relating to trade and commerce in any of the lists in the Seventh Schedule. Here, no reference is made to intercourse. But as the present controversy is not concerned with the freedom of intercourse, as distinguished from the freedom of trade and commerce, no more need be said about that omission. ( 13 ) LEARNED counsel for the appellants vehemently argued that the freedom contemplated by Art. 301 must be construed in its most comprehensive sense of freedom from all kinds of impediments, restraints and trade barriers, including freedom from all taxation. In my opinion, there is no warrant for such an extreme position. It has to be remembered that trade, commerce and intercourse include individual freedom of movement of every citizen of India from State of State, which is also guaranteed by Art. 19 (1) (d) of the Constitution. In my opinion, there is no warrant for such an extreme position. It has to be remembered that trade, commerce and intercourse include individual freedom of movement of every citizen of India from State of State, which is also guaranteed by Art. 19 (1) (d) of the Constitution. The three terms used in Art. 301 include not only free buying and selling but also the freedom of bargain and contract and transmission of information relating to such bargains and contracts as also transport of goods and commodities for the purpose of production, distribution and consumption in all their aspects, that is to say, transportation by land, air or water. They must also include commerce not only in goods and commodities, but also transportation of men and animals by all means of transportation. Commerce would thus include dealings over the telegraph, telephone or wireless and every kind of contract relating to sale, purchase, exchange, etc. , of goods and commodities. ( 14 ) VIEWED in this all comprehensive sense, taxation on trade, commerce and intercourse would have many ramifications and would cover almost the entire field of public taxation, both in the Union and in the State Lists. It is almost impossible to think that the makers of the Constitution intended to make trade, commerce and inter course free from taxation in that comprehensive sense. If that were so, all laws of taxation relating to sale and purchase of goods, on carriage of goods and commodities, men and animals, from one place to another, both inter-State and intra-State, would come within the purview of Art. 301 and the proviso to Art. 304 (b) would make it necessary that all Bills or amendments of pre-existing laws shall have to go through the gamut prescribed by that proviso. That will be putting too great an impediment to the power of taxation vested in the States and reduce the States limited sovereignty under the Constitution to a mere fiction. That extreme position has therefore, to be rejected as unsound. ( 15 ) IN this connection, it is also pertinent to bear in mind that all taxation is not necessarily an impediment or a restraint in the matter of trade, commerce and intercourse. That extreme position has therefore, to be rejected as unsound. ( 15 ) IN this connection, it is also pertinent to bear in mind that all taxation is not necessarily an impediment or a restraint in the matter of trade, commerce and intercourse. Instead of being such impediments or restraints, they may, on the other hand, provide the wherewithals to, improve different kinds of means of transport, for example, in cane growing areas, unless there are good roads, facility for transport of sugarcane from sugarcane fields to sugar mills may be wholly lacking or insufficient. In order to make new roads as also to improve old ones, cess on the grower of cane or others interested in the transport of this commodity has to be imposed, and has been known in some parts of India to have been imposed at a certain rate per md. or ton of sugarcane transported to sugar factories. Such an imposition is a tax on transport of sugarcane from one place to another, either intra-State or inter-State. It is the tax thus realised that makes it feasible for opening new means of communication or for improving old ones. It cannot, therefore, be said that taxation in every case must mean an impediment or restraint against free flow of trade and commerce. Similarly, for the facility of passengers and goods by motor transport or by railway, a surcharge on usual fares or freights is levied, or may be levied in future. But for such a surcharge, improvement in the means of communication may not be available at all. Hence, in my opinion, it is not correct to characterise a tax on movement of goods or passengers as necessarily connoting an impediment, or a restraing, in the matter of trade and commerce. That is another goods reason in support of the conclusion that taxation is not ordinarily included within the terms of Art. 301 of the Constitution. ( 16 ) IN my opinion, another very cogent reason for holding that taxation simpliciter is not within the terms of Art. 301 of the Constitution is that the very connotation of taxation is the power of the State to raise money for public purpose by compelling the payment by persons, both natural and juristic, of monies earned or possessed by them, by virtue of the facilities and protection afforded by the State. Such burdens or imposts, either direct or indirect, are in the ultimate analysis meant as a contribution by the citizens or persons residing in the State, or dealing with the citizens of the State for the support of the Government, with particular reference to their respective abilities to make such contributions. Thus public purpose is implicit in every taxation, as such. Therefore, when Part 13 of the Constitution speaks of imposition of reasonable restrictions in public interest, it could not have intended to include taxation within the generic term "reasonable restrictions. This Court has laid it down in the case of Ramjilal v. Income-tax Officer, Mohindargarh, 1951 SCR 127 that imposition and collection of taxes by authority of law envisaged by Art. 265 is outside the scope of the expression "deprivation of property in Art. 31 (1) of the Constitution. Reasonable restrictions as used in Part III or Part 13 of the Constitution would in most cases be less than total deprivation of property rights. Hence, Part XII dealing with finance etc. , as already indicated, has been treated as a Part dealing with the sovereign power of the State to impose taxes, which must always mean imposing burdens on citizens and others, in public interest. If a law is passed by the Legislature imposing a tax which in its true nature and effect is meant to impose an impediment to the free flow of trade, commerce and intercourse, for example, by imposing a high tariff wall, or by preventing imports into or exports out of a State, such a law is outside the significance of taxation, as such, but assumes the character of a trade barrier which it was the intention of the Constitution makers to abolish by Part. 13. The objections against the contention that taxation was included within the prohibition contained in Part 13 may thus be summarised: (1) Taxation, as such, always implies that it is in public interest. Hence, it would be outside particular restrictions, which may be characterised by the courts as reasonable and in public interest. (2) The power is vested in a sovereign State to carry on government. Our Constitution has laid the foundations of a welfare State, which means very much expanding the scope of the activities of Government and administration, thus making it necessary for the State to impose taxes on a much larger scale and in much wider fields. (2) The power is vested in a sovereign State to carry on government. Our Constitution has laid the foundations of a welfare State, which means very much expanding the scope of the activities of Government and administration, thus making it necessary for the State to impose taxes on a much larger scale and in much wider fields. The legislative entries in the three Lists referred to above empowering the Union Government and the State Government to impose certain taxations with reference to movement of goods and passengers would be rendered ineffective, if not otiose, if it were held that taxation simpliciter is within the terms of Art. 301. (3) If the argument on behalf of the appellants were accepted, many taxes, for example, sales tax by the Union and by the States, would have to go through the gamut prescribed in Arts. 303 and 304, thus very much detracting from the limited sovereignty of the States, as envisaged by the Constitution. (4) Laws relating to taxation, which is essentially a legislative function of the State, will become justiciable and every time a taxation law is challenged as unconstitutional, the State will have to satisfy the courts - a course which will seriously affect the division of powers on which modern constitutions, including ours, are based. (5) Taxation on movement of goods and passengers is not necessarily an impediment. ( 17 ) THAT conclusion leads to a discussion of the other extreme position that taxation is wholly out the purview of Article 301. That extreme position is equally untenable in view of the fact that Art. 304 contains, and Art. 306, before it was repealed in 1956, contained reference to taxation for certain purposes mentioned in those Articles. But Art. 306, which now stands repealed, contained references to tax or duty on the import of goods into one State from another or on the export of goods from one State to another. Such imposts were really in the nature of impediments to the free flow of goods and commodities on account of customs barriers, which it was the intention of Art. 301 to abolish. Similarly, Art. 304 while recognising the power of a State Legislature to tax goods imported inter-State, insists that a similar tax is imposed on goods manufactured or produced within the State. Similarly, Art. 304 while recognising the power of a State Legislature to tax goods imported inter-State, insists that a similar tax is imposed on goods manufactured or produced within the State. The Article thus brings out the clear distinction between taxation as such for the purpose of revenue and taxation for purposes of making discrimination or giving preference, both of which are treated by the Constitution as impediments to free trade and commerce. In order words, so long as the impost was not in the nature of an impediment to the free flow of goods and commodities between one State and another, including in this expression Union territories also, its legality was not subject to an attack based on the provisions of Part 13. But that does not mean that State Legislatures derive their power of taxation by virtue of what is contained in Art. 304. Article 304 only left intact such power of taxation, but contained the inhibition that such taxes shall not be permitted to have the effect of impeding the free flow of goods and commodities. ( 18 ) ARTICLE 301, with which Part 13 commences, contains the crucial words "shall be free" and provides the key to the solution of the problems posed by the whole Part. The freedom declared by this Article is not an absolute freedom from all legislation. As already indicated, the several entries in the three Lists would suggest that both Parliament and State Legislatures have been given the power to legislate in respect of trade, commerce and intercourse, but it is equally clear that legislation should not have the effect of putting impediments in the way of free flow of trade and commerce. In my opinion, it is equally clear that the freedom envisaged by the Article is not an absolute freedom from the incidence of taxation in respect of trade, commerce and intercourse, as shown by entries 89 and 92-A in List I, entries 52, 54 and 56 to 60 in List II and entry 35 in List III. All these entries in terms speak of taxation in relation to different aspects of trade, commerce and intercourse. All these entries in terms speak of taxation in relation to different aspects of trade, commerce and intercourse. The Union and State Legislature, therefore, have the power to legislate, by way of taxation in respect of trade, commerce and intercourse, so as not to erect trade barriers, tariff walls or imposts which have a deleterious effect on the free flow of trade, commerce and intercourse. That freedom has further been circumscribed by the power vested in Parliament or in the Legislature of a State to impose restrictions in the public interest. Parliament has further been authorised to legislate in the way of giving preference or making discrimination in certain strictly limited circumstances indicated in cl. (2) of Art. 303. Thus, on a fair construction of the provisions of Part 13, the following propositions emerge; (1) trade commerce and intercourse throughout the territory of India are not absolutely free, but are subject to certain powers of legislation by Parliament or the Legislature of a State; (2) the freedom declared by Art. 301 does not mean freedom from taxation simpliciter, but does mean freedom from taxation which has the effect of directly impeding the free flow of trade, commerce and intercourse; (3) the freedom envisaged in Art. 301 is subject to non-discriminatory restrictions imposed by Parliament in public interest (Art. 302); (4) even discriminatory or preferential legislation may be made by Parliament for the purpose of dealing with an emergency like a scarcity of goods in any part of India (Art. 303 (2)); (5) reasonable restrictions may be imposed by the Legislature of a State in the public interest (Art. 304 (b)); (6) non-discriminatory taxes may be imposed by the Legislature of a State on goods imported from another State or other States, if similar taxes are imposed on goods produced or manufactured in that State (Art. 304 (a)); and lastly (7) restrictions imposed by existing laws have been continued, except in so far as the President may by order otherwise direct (Art. 305 ). ( 19 ) AFTER having discussed the arguments for and against the proposition that Art. 301 includes within its large sweep taxation simpliciter, I now proceed to discuss the terms of the impugned Act in order to find out whether in the light of the discussion above, any of its provisions are liable to be struck down as unconstitutional, because they infringe Art. 301, as contended on behalf of the appellants. The Act, as the preamble shows, is intended to "impose a tax on certain goods carried by road or inland waterways". "dealer" has been defined in S. 2 (4) as under : " dealer means a person who owns jute in bales before it is carried by motor vehicle, cart, trolley, boat, animal and human agency or any other means except railways or airways and includes his agent". Producer has been defined by cl. (12) of S. 2 as follows: " Producer means a producer of tea and includes the person in charge of the garden where tea is produced". SECTION 3, which is the charging section, provides that manufactured tea in chests carried by motor vehicle, etc. , except railways and airways, shall be liable to a tax at a certain rate per pound of such tea and that this tax shall be realised from the producer. It also provides that jute carried in bales by motor vehicle, etc. , except railways and airways, shall be liable to a tax at a certain rate per maund on such jute, which shall be realised from the dealer. It is not necessary to set out the rate of taxes aforesaid, because no argument was advanced to the effect that they were oppressive or excessive. The tax on manufactured tea in chests is to be paid by the producer, which tern includes the person in charge of the garden where tea is produced. This provision has occasioned the argument that it is an excise duty in the garb of a tax and will be dealt with later in the course of this judgment. The tax on jute carried in bales is made realisable from the dealer which means a person who owns the jute in bales. S. 6 lays down the taxing authorities. S. 7 requires every producer and dealer to furnish returns of such tea or such jute as have been made liable to tax under S. 3, as aforesaid. The tax on jute carried in bales is made realisable from the dealer which means a person who owns the jute in bales. S. 6 lays down the taxing authorities. S. 7 requires every producer and dealer to furnish returns of such tea or such jute as have been made liable to tax under S. 3, as aforesaid. S. 8 makes provision for licensing of balers, which means persons who own or possess a pressing machine for the compression of jute into bales. S. 9 lays down the procedure of assessment and S. 10 the procedure for cancellation of assessment in certain circumstances. S. 11 lays down the procedure for assessment in such cases as have escaped assessment or there has been an evasion of the tax. It is not necessary to refer to the other provisions of the Act, because they are not relevant to the arguments advanced at the Bar. It will be seen from the bare summary of the relevant provisions of the statute that it is a taxing statute simpliciter without the least suggestion even of any attempt at discrimination against dealers and producers outside the State of Assam or of preference in favour of those inside the State. On the face of it, therefore, the Act does not suffer from any of the vices against which Part 13 of the Constitution was intended. It has not been suggested that the Act imposes a heavy burden on the dealer or the producer as the case may be. On the terms of the Statute, it cannot be said that it is intended to put obstacles or impediments in the way of free flow of traffic in respect of jute and tea. On the face of it, it would not be in the interest of the State of Assam to put any such impediments because Assam is a large producer of those commodities and the market for those commodities is mainly in Calcutta. In those circumstances, it is difficult, if not impossible, to come to the conclusion that the Act comes within the purview of Art. 301 of the Constitution. If that is so, no further consideration arising out of the other provisions of Part 13 of the Constitution calls for any decision. In those circumstances, it is difficult, if not impossible, to come to the conclusion that the Act comes within the purview of Art. 301 of the Constitution. If that is so, no further consideration arising out of the other provisions of Part 13 of the Constitution calls for any decision. ( 20 ) HAVING thus disposed of the main ground of attack against the constitutionality of the Act based on Art. 301 of the Constitution, it is necessary to advert to the other contentions raised on behalf of the appellants. It has been contended that the Act is beyond the legislative competence of the Assam Legislature. We have, therefore, to address ourselves to the question whether or not it is covered by any of the entries in List II of the Seventh Schedule. Entry 56, in its very terms, "taxes on goods and passengers carried by rail or on inland waterways", completely covers the impugned Act. There is no occasion in this case to take recourse to the doctrine of pith and substance, inasmuch as the Act is a simple piece of taxing statute meant to tax transport of goods, in this case jute and tea, by road or on inland waterways. In my opinion, it is a very simple case of taxation completely covered by entry 56, but the argument against the competence of the Assam Legislature has been sought to be supported by the subsidiary contention that though in form it is a tax on the transport of goods within the terms of entry 56, in substance it is an imposition of excise duty within the meaning of entry 84 in List I of the Seventh Schedule, but, in my opinion, there is no substance in this contention for the simple reason that so long as jute or tea is not sought to be transported from one place to another, within the State or outside the State, no tax is sought to be levied by the Act. It is only when those goods are put on a motor truck or a boat or a steamer or other modes of transport contemplated by the Act, that the occasion for the payment of tax arises. A similar argument was advanced in the case of Tata Iron and Steel and Co. It is only when those goods are put on a motor truck or a boat or a steamer or other modes of transport contemplated by the Act, that the occasion for the payment of tax arises. A similar argument was advanced in the case of Tata Iron and Steel and Co. Ltd. v. State of Bihar, (1958) SCR 1355: ( AIR 1958 SC 452 ), and Das, C. J. , delivering the majority judgment of the Court, disposed of the argument that the tax in that case was not on sale of goods, but was, in substance, a duty of excise, in these terms : "this argument, however, overlooks the fact that under cl. (ii) the producer or manufacturer became liable to pay the tax not because he produced or manufactured the goods, but because he sold the goods. In other words the tax was laid on the producer or manufacturer only qua seller and not qua manufacturer or producer as pointed out in Province of Madras v. Boddu Paidanna and Sons, 1942 FCR 90: (AIR 1942 FC 33 ). In the words of their Lordships of the Judicial Committee in Governor-General v. Province of Madras, 72 Ind App 91 a duty of excise is primarily a duty levied on a manufacturer or producer in respect of the commodity manufactured or produced. It is a tax on goods not on sales or the proceeds of sale of goods. If the goods produced or manufactured in Bihar were destroyed by fire before sale the manufacturer or producer would not have been liable to pay any tax under S. 4 (1) read with S. 2 (g), second proviso. As Gwyer, C. J. , said in Boddu Paidannas case, 1942 FCR 90 , the manufacturer or producer would be liable if at all, to a sales tax because he sells and not because he manufacture or produces; and he would be free from liability if he would be free from liability if he chose to give away everything which came from his factory. ". THE observations quoted above completely cover the present controversy. The Legislature has chosen the dealer or the producer as the convenient agency for collection of the tax imposed by S. 3, but the occasion for the imposition of the tax is not the production or the dealing but the transport of those goods. ". THE observations quoted above completely cover the present controversy. The Legislature has chosen the dealer or the producer as the convenient agency for collection of the tax imposed by S. 3, but the occasion for the imposition of the tax is not the production or the dealing but the transport of those goods. It must, therefore, be held that the Act does what it sets out to do, namely, to impose a tax on goods carried by road or on inland waterways. ( 21 ) ANOTHER line of argument directed to the same end, namely, of attacking the competence of the Assam Legislature was that it impinged on the provisions of the Tea Act, 29 of 1953. It was argued that the tea industry was a controlled one within the competence of the Union Legislature. The Tea Act declared that it was expedient in the public interest that the Union should take the tea industry under its control. With a view to controlling the industry in public interest the Act established the Tea Board (S. 4) whose function it was, inter alia, to regulate the production and extent of cultivation of tea, of improving the quality of tea, of promoting co-operative effort among growers and manufactures or tea etc. , etc. , (S. 10 ). With the objectives aforesaid, Ch. III lays down provisions for the control over the extension of tea cultivation and Ch. IV deals with provisions for control over the export of tea and tea seed. Chapter 5 lays down provisions for the imposition of duty of customs on export of tea outside India and the proceeds of the cess thus levied have to be credited to the Consolidated Fund of India. Out of that Fund, called the Tea Fund, the expenses of the establishment created by the Tea Act have to be met. The rest of the provisions of the Act are meant to implement the main provisions of the Act. There are no provisions of the Tea Act which can be said to come into conflict with the provisions of the impugned Act. In our opinion, therefore, this ground of attack also fails. The rest of the provisions of the Act are meant to implement the main provisions of the Act. There are no provisions of the Tea Act which can be said to come into conflict with the provisions of the impugned Act. In our opinion, therefore, this ground of attack also fails. ( 22 ) A third line of argument against the constitutionality of the Act was that it is extra-territorial in its operation in so far as it purports to tax producers and dealers who may not be residents of the State of Assam. This argument has been advanced in the interest of the appellants and petitioners from West Bengal, who have to carry their goods by road or on waterways passing through the territory of Assam, from one part of West Bengal to another. So far as this group of cases is concerned, the main grievance of the appellants is that no doubt their goods have to pass through a portion of the territory Assam, but the goods have been produced, packed and transported as merchandise from one part of West Bengal to another part of the same State. It is not denied that there is some real and substantial nexus to support the taxing statute, but it is contended that relatively to the whole journey to be covered by the merchandise, the portion of the territory of Assam covered in that journey is very small. But in judging the validity of a legislation with reference to the contention based on extra-territoriality it is not relevant to consider the question of the proportion between the extent of territorial nexus to the whole length of the journey. If goods belonging to or carried by the appellants traverse any of the territory of Assam the taxation cannot be successfully assailed on this ground, once it is held that it was within the legislative competence of the Legislature imposing the tax in question. where Das, C. J. , speaking for the majority of the Court, has examined the theory of nexus with reference to a large body of case law bearing on the question. I respectfully adopt that line of reasoning and hold that the Act does not suffer from the vice of extra-territoriality. where Das, C. J. , speaking for the majority of the Court, has examined the theory of nexus with reference to a large body of case law bearing on the question. I respectfully adopt that line of reasoning and hold that the Act does not suffer from the vice of extra-territoriality. It is true that the incidence of the taxation may fall upon persons not ordinarily residing in the State of Assam or upon goods not produced in Assam, but, in this connection, it is enough to point out that what has been said above in respect of the tax being in the nature of a duty of excise applies with equal force to this part of the argument also. The tax is leviable from such goods as traverse in their journey any part of the territory of Assam, not because the owners or the producers are residents of Assam, but because the waterway or the roadway situate in the territory of Assam has been utilised for a portion of the journey. It is clear, therefore, that there is no infirmity attaching to the Act on the ground that it is extra-territorial in its operation. ( 23 ) IT only remains to consider the last ground of attack, namely, that the Act is discriminatory in character and thus infringes Art. 14 of the Constitution. In this connection, it has been argued that only tea in chests and jute in bales have been selected for taxation, leaving the same commodities in other hands or in other forms, or in other receptacles free from the incidence of the taxation in question. The Legislature has chosen to tax the transport over land or over waterways of those commodities, in chests or in bales, apparently because those are the most convenient and usually employed methods of packing for carriage of those goods to long distances. Hence, it is not a case of choosing for the purposes of taxation one class of goods in preference to another class of the same variety. The Legislature was out to tax the transport of those commodities and must be presumed to have selected the most convenient way of doing it. It has not been suggested that any large amount of such commodities is transported over long distances, otherwise than in chests or bales. The Legislature was out to tax the transport of those commodities and must be presumed to have selected the most convenient way of doing it. It has not been suggested that any large amount of such commodities is transported over long distances, otherwise than in chests or bales. Furthermore, if the Legislature has to tax something, it is not bound to tax that thing in all its forms and varieties. It may pick and choose with a view to raising such amount of revenue as it sets out to do. It is not for the courts to say that there were other ways of dong the thing or that all forms and varieties should have been brought under the scope of the taxation. It is open to the Legislature to impose a tax in a form and in a way which it deems most convenient for the purposes of collection and calculation of the tax. ( 24 ) AS all the grounds of attack raised against the constitutionality of the Act fail, the appeals and the petitions, in my opinion, should be dismissed with costs. ( 25 ) I have deliberately refrained from making references to or relying upon decisions from other countries like the U. S. A. or Australia, because the cases decided in those countries cannot be any guide for the solution of the problems raised in this case inasmuch as the framework of the Constitution in those countries is not in pari materia with ours. Any precedents deciding cases on the construction of statutes, which are worded differently from ours, cannot, in my opinion, be a safe guide for the decision of controversies raised in terms of our Constitution. ( 26 ) I regret to have to differ from the majority of the Court, but my only justification for taking a different view is that my reading of Part 13 of the Constitution does not justify the inference that taxation simpliciter is within the terms of Art. 301 of the Constitution. ( 26 ) I regret to have to differ from the majority of the Court, but my only justification for taking a different view is that my reading of Part 13 of the Constitution does not justify the inference that taxation simpliciter is within the terms of Art. 301 of the Constitution. ( 27 ) THE vexed question posed by the construction of the provisions of Part 13 of the Constitution which has been incidentally discussed in some reported decisions of this Court falls to be considered in the present group of cases This group consists of three appeals brought to this Court with a certificate issued by the Assam High Court under Art. 132 and two petitions filed under Art. 32. The three appellants are tea companies, two of which (Civil Appeal No. 126 of 1958 and Civil Appeal No. 128 of 1958) carry on their trade of growing tea in the District of Sibsagar in Assam while the third (Civil Appeal No. 127 of 1958) carries on its trade in Jalpaiguri in West Bengal. All the three companies which would be described hereafter as the appellants carry their tea to Calcutta in order that it may be sold in the Calcutta market for home consumption or export outside India. Tea produced in Jalpaiguri has also to pass through a few miles of territory in the State of Assam, while the tea produced in Assam has to go all the way through Assam to reach Calcutta. It appears that a very small proportion of tea produced and manufactured in Assam finds a market in Assam itself; bulk of it finds its custom in the market at Calcutta. Besides the tea which is carried by rail a substantial quantity has to go by road or by inland waterways and as such it becomes liable to pay the tax leviable under the Assam Taxation (on goods carried by Roads or Inland Waterways) Act, 1954 (Act 13 of 1954) (hereafter called the Act ). The Act has been passed by the Assam Legislature in order to provide for the levy of a tax on certain goods carried by road or inland waterways in the State of Assam and it has received the assent of the Governor on 9/04/1954. The Act has been passed by the Assam Legislature in order to provide for the levy of a tax on certain goods carried by road or inland waterways in the State of Assam and it has received the assent of the Governor on 9/04/1954. On behalf of the State of Assam, which will be described hereafter as respondent, its officers required the appellants to comply with the several requirements imposed by the Act, and made tax demands on them in respect of the tea carried by them. The tax this demanded was paid by the appellants under protest, and soon thereafter petitions were filed in the Assam High Court under Art. 226 challenging the validity of the Act as well as the tax demands made by the officers of the respondent. By their respective petitions the appellants prayed that a writ of mandamus should issue directing the respondent and its officers to forbear from giving effect to the provisions of the Act and from otherwise enforcing it against the appellants. The petitions also claimed alternatively a writ of prohibition or any other appropriate writ restraining the respondent and its officers from enforcing the Act against the appellants. That is how the validity of the Act came before the Assam High Court for judicial scrutiny. ( 28 ) THE appellants challenged the vires of the Act on several grounds. The principal ground, however, was that the Act has violated the provisions of Art. 301 of the Constitution, and since it did not comply with the provisions of Art. 304 (b) it was ultra vires. It was also urged that tea was a controlled industry under the provisions of Act 29 of 1953, and so it was the Union Government alone which was competent to regulate the manufacture, production, distribution or transport of the said commodity; that being so the Assam Legislature was not competent to pass the Act. It was also urged that tea was a controlled industry under the provisions of Act 29 of 1953, and so it was the Union Government alone which was competent to regulate the manufacture, production, distribution or transport of the said commodity; that being so the Assam Legislature was not competent to pass the Act. The validity of the Act was further challenged on the ground that, though the Act purported to have been passed under Entry 56 of Schedule II, in substance and in reality it was a duty of excise and as such it could be enacted only under Entry 84 of List I. According to the appellants the Act also suffered from the vice that it was violative of the fundamental right of equality before the law guaranteed by Art. 14 ( 29 ) THE correctness of these contentions was disputed by the respondent. It urged that the Act was perfectly within the competence of the Assam Legislature under Entry 56 of List II and that the provisions of Part 13 were wholly inapplicable to it. The respondent further pleaded that Art. 14 had not been violated and that there was no substance in the argument that as controlled industry it is only the Union Government which could deal with it or that in reality the Act had imposed a duty of excise. ( 30 ) THE petitions filed by the appellants were heard by a Special Bench of the Assam High Court. All the pleas raised by the appellants were rejected by Sarjoo Prasad, C. J. and Ram Labhaya, J. who delivered separate but concurring judgments. The appellants then applied for and obtained a certificate from the High Court under Art. 132; that is how the three appeals have come to this Court, and they raise for our decision all the points which were argued before the High Court. Naturally the principal contention which has been urged before is at length centres round the applicability of Part 13. ( 31 ) THE two petitions filed under Art. 32 arise substantially the same question. The petitioners are tea companies which carry on the trade of growing and manufacturing tea in Jalpaiguri in West Bengal. Naturally the principal contention which has been urged before is at length centres round the applicability of Part 13. ( 31 ) THE two petitions filed under Art. 32 arise substantially the same question. The petitioners are tea companies which carry on the trade of growing and manufacturing tea in Jalpaiguri in West Bengal. The respondent has attempted to subject the petitioners to the provisions of the Act, and the petitioners have challenged the authority of the respondent to levy a tax against them under the Act on the ground that the Act is ultra vires. Since the principal question raised in these appeals appeared to be of considerable importance in which other States may also be interested we directed that notice should be issued to the Attorney-General of India and the Advocate-Generals in all the States of India. Accordingly the Attorney-General appeared before us and the States of Bihar, Madras, Punjab, Rajasthan and Uttar Pradesh have also been heard. ( 32 ) THE challenge to the vires of the Act on the round that it contravenes Art. 301 necessarily raises the question about the construction of the relevant provisions in the said Part. Article 301 with which Part 13 begins provides that "subject to the other provisions of this Part trade commerce and intercourse throughout the territory of India shall be free". The appellants contend that this provision imposes a limitation on the legislative power of the State Legislatures as well as the Parliament, and the vires of the Act will have to be judge on the basis. The words used in Art. 301 are wide and unambiguous and it would be unreasonable to exclude from their ambit a taxing law which restricts trade, commerce or intercourse either directly or indirectly. On the other hand, the respondent the Attorney-General, and the other States have urged that taxing laws stand by themselves; they are governed by the provisions of Part XII and no provision of Part 13 can be extended to them. In the alternative it has been suggested that the provisions of Part 13 should be applied only to such legislative entries in the Seventh Schedule which deal with trade, commerce and intercourse. In the alternative it has been suggested that the provisions of Part 13 should be applied only to such legislative entries in the Seventh Schedule which deal with trade, commerce and intercourse. This alternative argument would bring within the purview of Part 13 Entry 42 in List I which refers to inter-State trade and commerce, Entry 26 in List II which deals with trade and commerce within the State subject to the provisions of Entry 33 in List III, and Entry 33 in List III which deals with trade and commerce as therein specified. The arguments thus presented by both the parties appear prima facie to be logical and can claim the merit of attractive simplicity. The question which we have to decide is which of the contentions correctly represents the true position in law. Does truth lie in one or the other contentions raised by the parties, or does it lie midway between those contentions? This problem has to be resolved primarily by adopting a fair and reasonable construction of the relevant Articles in Part 13; but before we attempt that task it would be relevant to deal with some general considerations. ( 33 ) LET us first recall the political and constitutional background of Part 13. It is a matter of common knowledge that, before the Constitution was adopted, nearly two-thirds of the territory of India was subject to British Rule and was then known as British India, while the remaining part of the territory of India was governed by Indian Princes and it consisted of several Indian States. A large number of these States claimed sovereign rights within the limitations imposed by the paramount power in that behalf, and they purported to exercise their legislative power of imposing taxes in respect of trade and commerce which inevitably led to the erection of customs barriers between themselves and the rest of India. In the matter of such barriers British India was governed by the provisions of S. 297 of the Constitution Act, 1935. To the provisions of this section we will have occasion later to refer during the course of this judgment. Thus prior to 1950 the flow of trade and commerce was impeded at several points which constituted the boundaries of Indian States. To the provisions of this section we will have occasion later to refer during the course of this judgment. Thus prior to 1950 the flow of trade and commerce was impeded at several points which constituted the boundaries of Indian States. After India attained political freedom in 1947 and before the Constitution was adopted the historical process of the merger and integration of the several Indian States with the rest of the country was speedily accomplished with the result that when the Constitution was first passed the territories of India consisted of Part. A States which broadly stated represented the Provinces in British India, and Part B States which were made up of Indian States. This merger or integration of Indian States with the Union of India was preceded by the merger and consolidation of some of the States inter se between themselves. It is with the knowledge of the trade barriers which had been raised by the Indian States in exercise of their legislative powers that the Constitution-makers framed the Articles in Part 13. The main object of Art. 301 obviously was to allow the free flow of the stream of trade, commerce and intercourse throughout the territory of India. ( 34 ) IN drafting the relevant Articles of Part 13 the makers of the Constitution were fully conscious that economic unity was absolutely essential for the stability and progress of the federal polity which had been adopted by the Constitution for the governance of the country. Political freedom which had been won, and political unity which had been accomplished by the Constitution, had to be sustained and strengthened by the bond of economic unity. It was realised that in course of time different political parties believing in different economic theories or ideologies may come in power in the several conceivably give rise to local and regional pulls and pressures in economic matters. Local or regional fears or apprehensions raised by local or regional problems may persuade the State Legislatures to adopt remedial measures intended solely for the protection of regional interests without due regard to their effect on the economy of the nation as a whole. The object of Part III was to avoid such a possibility. Free movement and exchange of goods throughout the territory of India is essential for the economy of the nation and for sustaining and improving living standards of the country. The object of Part III was to avoid such a possibility. Free movement and exchange of goods throughout the territory of India is essential for the economy of the nation and for sustaining and improving living standards of the country. The provision contained in Art. 301 guaranteeing the freedom of trade, commerce and intercourse is not a declaration of a mere platitude, or the expression of a pious hope of a declaratory character; it is not also a mere statement of a directive principle of State policy; it embodies and enshrines a principle of paramount importance that the economic unity of the country will provide the main sustaining force for the stability and progress of the political and cultural unity of the country. In appreciating the significance of these general considerations we may profitably refer to the observations made by Cardozo J. in Charles H. Baldwin v. G. A. F. Seeling, (1934) 294 US 511 : 79 Law Ed 1032 while he was dealing with the commerce cause contained in Art. 1, S. 8, cl. 3 of the American Constitution. "this part of the Constitution" observed Cardozo J. , "was framed under the dominion of a political philosophy less parochial in range. It was framed upon the theory that the peoples of the several states must sink or swim together and that in the long run prosperity and salvation are in union and not division. " ( 35 ) THERE is another general consideration which has been pressed before us by the learned Attorney-General and the States to which reference must be made. It is argued that in determining the scope and reach of the freedom embodied in Art. 301 we should bear in mind the fact that to the extent to which the frontiers of this freedom are widened to that extent is the legislative power of the States curtailed or limited. The Legislatures of the States have plenary powers to legislate in respect of topics covered by the legislative entries in Lists II and III. If the words used in Art. 301 receive the widest interpretation as contended by the appellants it would obviously mean that the State Legislatures wold not be able to legislate on several entries in the said Lists without adopting the procedure prescribed by Art. 304 (b ). If the words used in Art. 301 receive the widest interpretation as contended by the appellants it would obviously mean that the State Legislatures wold not be able to legislate on several entries in the said Lists without adopting the procedure prescribed by Art. 304 (b ). In fact it would be unreasonable to impose such a limitation on the legislative power of the State Legislatures and thereby affect their freedom of action. Whilst appreciating this argument it may be pertinent to observe that what appears as a curtailment of, or limitation on, the powers of the State Legislatures prescribed by Art. 304 (b) may, from the point of view of national economy, be characterised as a safeguard deliberately evolved to protect the economic unity of the country; even so it may be assumed that in interpreting the provisions of Art. 301 and determining the scope and effect of Part 13 we should bear in mind the effect of our decision on the legislative power of the States and also of Parliament. ( 36 ) HAVING thus referred to some general considerations let us now proceed to examine the question as to whether tax laws are wholly outside the purview of Part 13. In support of the argument that Part 13 does not apply to tax laws the learned Attorney-General has emphasised the fact that the power to levy a tax is an essential part of sovereignty itself, and the has suggested that this power is not subject to judicial review and never has been held to be so. In this connection he has invited our attention to the observations made in Cooley's "constitutional Limitations" on the power of taxation. "the power to impose taxes", says the author, "is one so unlimited in force and so searching in extent, that the courts scarcely venture to declare that it is subject to any restriction whatever, except such as rest in the discretion of the authority which exercises it" (Cooley's "constitutional Limitations", ). "the power to impose taxes", says the author, "is one so unlimited in force and so searching in extent, that the courts scarcely venture to declare that it is subject to any restriction whatever, except such as rest in the discretion of the authority which exercises it" (Cooley's "constitutional Limitations", ). THE author then has cited the observations of Marshall C. J. in Mccullock v. Maryland, (1879) 4 Wheat 316 where the learned Chief Justice has stated that "the power of taxing the people and their property is essential to the very existence of the government, and may be legitimately exercised on the object to which it is applicable to the utmost extent to which the government may choose to carry it. The only security against the abuse of this power is found in the structure of the government itself" BASING himself on this character of the taxing power of the State the learned Attorney-General has asked us to hold that Part 13 can have no application to any statute imposing a tax. In our opinion this contention is not well founded. The statement of the law on which reliance has been placed is itself expressed to be subject to the relevant provisions of the Constitution; for instance, the same author has observed - "it is also believed that that provision in the Constitution of the United States which declares that the citizens of each state shall be entitled to all the privileges and immunities of the citizens of the several States will preclude any State from imposing upon the property which citizens of other State may own, or the business which they may carry on within its limits, any higher burdens by way of taxation than are imposed upon corresponding property or business of its own citizens". PUTTING the same propositions in terms of our Constitution it cannot be suggested that the power of taxation can, for instance violate the equality before law guaranteed by Art. 14 of the Constitution. Therefore the true position appears to be that, though the power of levying tax is essential for the very existence of the government, its exercise must inevitably be controlled by the constitutional provisions made in that behalf. It cannot be said that the power of taxation per se is outside the purview of any constitutional limitations. Therefore the true position appears to be that, though the power of levying tax is essential for the very existence of the government, its exercise must inevitably be controlled by the constitutional provisions made in that behalf. It cannot be said that the power of taxation per se is outside the purview of any constitutional limitations. ( 37 ) IT is true that in 1951 SCR 127 : ( AIR 1951 SC 97 ) it has been held that "since there is a special provision in Art. 265 of the Constitution that no tax shall be levied or collected except by authority of law, cl. (1) of Art. 31 must be regarded as concerned with deprivation of property otherwise than by the imposition or collection of tax, and so, as the right conferred by Art. 265 is not a right by Part III of the constitution, it could not be enforced under Art. 32". IT is clear that the effect of this decision is no more than this that the protection against the imposition and collection of taxes, save by the authority of law, directly comes under Art. 265 and cannot be said to be covered by cl. (1) of Art. 31. It would be unsafe to assume that this decision is, or was intended to be an authority for the proposition that the levy of a tax by taxing statute can, for instance, violate Art. 14 of the Constitution. ( 38 ) THE next question which needs examination is whether tax laws are governed only by Part XII of the Constitution and not by Part 13. The argument is that Part XII is a self-contained Code; it makes all necessary provisions, and so the validity of any taxing statute can be judged only by reference to the provisions of the said Part. Article 265 provides that "no tax shall be levied or collected except by authority of law. " It is emphasised that this Article does not contemplate that its provision is subject to the other provisions of the Constitution, and so there would be no justification for applying Part 13 to the taxing statutes. It is also pointed out that restriction and other exceptions which the Constitution wanted to prescribe in respect of taxation have been provided for by Arts. It is also pointed out that restriction and other exceptions which the Constitution wanted to prescribe in respect of taxation have been provided for by Arts. 274, 276, 285, 287 and 288, and so we need not look beyond the provisions of this Part in dealing with tax laws. In our opinion this dealing with tax laws. In our opinion this argument fails to take notice of the fact that Art. 265 itself inevitably takes in Art. 245 of the Constitution when in substance it says that a tax shall be levied by authority of law. The authority of law to which it refers and under which alone a tax can be levied is to be found in Art. 245 read with the corresponding legislative entries in Schedule VII. Now, if we look at Art. 245 which deals with the extent of laws made by Parliament and by the Legislatures of States it begins with the words "subject to the provisions of this Constitution"; in other words, the power of Parliament and the Legislatures of the States to make laws including laws imposing taxes is subject to the provisions of this Constitution and that must bring in the application of the provisions of Part 13. Therefore the argument based on the theory that tax laws are governed by the provisions of Part XII alone cannot be accepted. The power to levy taxes is ultimately based on Art. 245, and the said power in terms is subject to the provisions of the Constitution. ( 39 ) ON the other hand, the opening words of Art. 301 are very significant. The doctrine of the freedom of trade, commerce and intercourse enunciated by Art. 301 is not subject to the other provisions of the Constitution but is made subject only to the other provisions of Part 13; that means that once the width and amplitude of the freedom enshrined in Art. 301 are determined they cannot be controlled by any provision outside Part 13. This position incidentally brings out in bold relief the important part which the Constitution makers wanted the doctrine of freedom of trade to play in the future of the country. This position incidentally brings out in bold relief the important part which the Constitution makers wanted the doctrine of freedom of trade to play in the future of the country. It is obvious that whatever may be the content of the said freedom it is not intended to be an absolute freedom; absolute freedom in matters of trade, commerce and intercourse would lead to economic confusion, if not chaos and anarchy; and so the freedom guaranteed by Art. 301 is made subject to the exceptions provided by the other Articles in Part 13. The freedom guaranteed is limited in the manner specified by the said Articles but it is not limited by any other provisions of the Constitution outside Part 13. That is why it seems to us that Art. 301, read in its proper context and subject to the limitations prescribed by the other relevant Articles in Part 13, must be regarded as imposing a constitutional limitation on the legislative power of Parliament and the Legislatures of the States. What entries in the legislative lists will attract the provisions of Art. 301 is another matter; that will depend upon the content of the freedom guaranteed; but wherever it is held that Art. 301 applies, the legislative competence of the Legislature in question will have to be judged in the light of the relevant Articles of Part 13; this position appears to us to be inescapable. ( 40 ) ON behalf of the respondent it was suggested before us that the scope and extent of the application of Art. 301 can well be determined in the light of S. 297 of the Constitution Act 1935. S. 297 reads thus : "297 (1 ). ( 40 ) ON behalf of the respondent it was suggested before us that the scope and extent of the application of Art. 301 can well be determined in the light of S. 297 of the Constitution Act 1935. S. 297 reads thus : "297 (1 ). No Provincial Legislature or Government shall - (A) by virtue of the entry in the Provincial Legislative List relating to trade and commerce within the Province, or the entry in that List relating to the production, supply, and distribution of commodities, have power to pass any law or take any executive action prohibiting or restricting the entry into, or export from the Province of goods of any class or description; or (B) by virtue of any thing in this Act have power to impose any tax, cess, toll, or due which, as between goods manufactured or produced in the Province and similar goods not so manufactured or produced, discriminates in favour of the former, or which, in the case of goods manufactured or produced outside the Province, discriminates between goods manufactured or produced in one locality and similar goods manufactured or produced in another locality. (2) Any law passed in contravention of this section shall, to the extent of the contravention, be invalid. " THERE is no doubt that the prohibition prescribed by this section was confined to the Provincial Governments and Provincial Legislatures and did not apply to the Central Government or Central Legislature. It is also true that the said prohibition had reference to the entries in the Provincial Legislative List relating to trade and commerce, and to production, supply and distribution of commodities. The section also deals with prohibitions and restrictions in respect of import of goods into, or their export from, a Province. Likewise discrimination against goods manufactured or produced outside the Province or goods produced in other localities is also prohibited. The section also deals with prohibitions and restrictions in respect of import of goods into, or their export from, a Province. Likewise discrimination against goods manufactured or produced outside the Province or goods produced in other localities is also prohibited. The argument is that when the Constitution adopted Art. 301 it had S. 297 in view and the only substantial change which it intended to make was to extend the application of the principles enunciated in the said section to the Union Government and the Union Parliament and to apply it to the territory which had subsequently become a part of India as indicated by the relevant Articles; the essential content of freedom of trade and commerce as prescribed by the said section, however, continues to be the same. ( 41 ) IN support of this argument reliance has been placed on the observations made by Venkatarama Aiyar, J. , in the case of M. P. V. Sundaramier and Co. , v. State of Andhra Pradesh, (1958) SCR 1422. In that case the vires of some of the provisions of the Madras General Sales Tax Laws (Validation) Act, 7 of 1956 were challenged on several grounds. In dealing with one of the points raised in support of the said challenge, Venkatarama Aiyar, J. , who delivered the majority judgment, considered the content of Entry 42 in List I. It had been urged before the Court that the said entry should be liberally construed and should be held to include the power to tax, and in support of this contention reliance was placed on certain American and Australian decisions. This argument was repelled and it was held that Entry 42 in List I is not to be interpreted as including taxation. In coming to this conclusion the learned Judge made certain general observations pointing out that it would not be always safe to rely upon American or Australian decisions in interpreting the provisions of our Constitution. Said the learned Judge : "the threads of our Constitution were no doubt taken from other Federal Constitutions but when they were woven into the fabric of our Constitution their reach and their complexion underwent changes. Therefore, valuable as the American decision are as showing how the question is dealt with in sister Federal Constitution great care should be taken in applying them in the interpretation of our Constitution. Therefore, valuable as the American decision are as showing how the question is dealt with in sister Federal Constitution great care should be taken in applying them in the interpretation of our Constitution. " HE made a similar comment about S. 92 of the Commonwealth of Australia Constitution Act and the decisions thereunder, and in that connection he observed : "we should also add that Art. 304 (a) of the Constitution cannot be interpreted as throwing any light on the scope of Art. 301 with reference to the question of taxation as it merely reproduces S. 297 (1) (b) of the Government of India Act, and as there was no provision therein corresponding to Art. 301, S. 297 (1) (b) could not have implied what is now sought to be inferred from Art. 304 (a ). " THE learned Attorney-General has relied on these observations. It would be noticed that, incidental as these observations are, what the learned Judge was considering was the scope and effect of S. 297 (1) (b) of the Government of India Act, 1935, and he held that the content of the said section cannot be enlarged in the light of the provisions of Art. 304 (a ). No doubt the observations would seem to show that the learned Judge thought that Art. 304 (a) cannot throw any light on the scope of Art. 301 with reference to the question of taxation; but it is clear that the question of construing the said Articles did not fall to be considered, and was not obviously argued before the Court. With respect, it may be pointed out that in the happy phraseology adopted by the learned Judge himself, in the setting of Part 13 and particularly in the light of the wide words used in Art. 301, the reach and complexion of Art. 304 (a) is wider than S. 297 (1) (b) and does include reference to taxation. ( 42 ) THEN as to the merits of the argument that S. 297 of the Constitution Act of 1935 should virtually determine the scope of Art. 301, we are reluctant to accept the assumption that the only change which the Constitution makers intended to make by adopting Art. 301 was to extend the application of S. 297 to the Union Government and the Parliament. Just as the Constitution makers had before them the said section they were also familiar with corresponding clauses included in the Federal Constitutions of other countries. The history of judicial decisions interpreting S. 92 of the Australian Constitution must have been present to their minds as also the history of the growth and development of the American Law under the commerce clause in the American Constitution. Besides, we feel considerable hesitation in accepting the view that the makers of the Constitution did no want to enrich and widen the content of freedom guaranteed by S. 297. They knew that the Constitution would herald a new and inspiring era in the history of India and they were fully conscious of the importance of maintaining the economic unity of the Union of India in order that the Federal form of government adopted by the Constitution should progress in a smooth and harmonious manner. That is why we are inclined to hold that the broad and unambiguous words used in Art. 301 are intended to emphasise that the freedom of trade, commerce and intercourse guaranteed was richer and wider in content than was the case under S. 297; how much wider and how much richer can be determined only on a fair and reasonable construction of Art. 301 read along with the rest of the Articles in Part 13. In our opinion, therefore, the argument that tax laws are outside Part 13 cannot be accepted. ( 43 ) THAT takes us to the question as to whether Art. 301 operates only in respect of the entries relating to trade and commerce already specified. Before answering this question it would be necessary to examine the scheme of Part 13, and construe the relevant Articles in it. It is clear that Art. 301 applies not only to inter-State trade, commerce and intercourse but also intra-State trade, commerce and intercourse. The words "throughout the territory of India" clearly indicate that trade and commerce whose freedom is guaranteed has to move freely also from one place to another in the same State. This conclusion is further supported by Arts. 302 and 304 (b) as we will presently point out. The words "throughout the territory of India" clearly indicate that trade and commerce whose freedom is guaranteed has to move freely also from one place to another in the same State. This conclusion is further supported by Arts. 302 and 304 (b) as we will presently point out. There is no doubt that the sweep of the concept of trade, commerce and intercourse is very wide; but in the present case we are concerned with trade, and so we will leave out of consideration commerce and intercourse. Even as to trade it is really not necessary to discuss or determine what trade exactly means; for it is common ground that the activity carried on by the appellants amounts to trade, and it is not disputed that transport of goods or merchandise from one place to another is so essential to trade that it can be regarded as its integral part. Stated briefly trade even in a narrow sense would include all activities in relation to buying and selling, or the interchange or exchange of commodities and that movement from place to place is the very soul of such trading activities. When Art. 301 refers to the freedom of trade it is necessary to enquire what freedom means. Freedom from what? Is the obvious question which falls to be determined in the context. At this stage we would content ourselves with the statement that the freedom of trade guaranteed by Art. 301 is freedom from all restrictions except those which are provided by the other Articles in Part 13. What these restrictions denote may raise a larger issue, but in the present case we will confine our decision to that aspect of the matter which arises from the provisions of the Act under scrutiny. It is hardly necessary to emphasise that in dealing with constitutional questions courts should be slow to embark upon an unnecessarily wide or general enquiry and should confine their decision as far as may be reasonably practicable within the narrow limits of the controversy arising between the parties in the particular case. We will come back again to Art. 301 after examining the other Articles in Part 13. ( 44 ) ARTICLE 302 confers on the Parliament power to impose restrictions on trade, commerce and intercourse. We will come back again to Art. 301 after examining the other Articles in Part 13. ( 44 ) ARTICLE 302 confers on the Parliament power to impose restrictions on trade, commerce and intercourse. It provides that Parliament may by law impose such restrictions on the freedom of trade, commerce or intercourse between one State and another or within any part of the territory of India as may be required in the public interest. It would be immediately noticed that the reference made to restriction on the freedom of trade within any part of the territory of India as distinct from freedom of trade between one State and another clearly indicates that the freedom in question covers not only inter-State trade but also intra-State trade. Thus the effect of Art. 302 is to provide for an exception to the general rule prescribed by Art. 301. Restrictions on the freedom of trade can be imposed by Parliament if they are required in the public interest so that the generality of freedom guaranteed by Art. 301 is subject to the exception provided by Art. 302. THAT takes us to Art. 303. It reads thus : "303. (1) Notwithstanding anything in Art. 302, neither Parliament nor the Legislature of a State shall have power to make any law giving, or authorising the giving of, any preference to one State over another, or making, or authorising the making of, any discrimination between one State and another, by virtue of any entry relating to trade and commerce in any of the Lists in the Seventh Schedule. (2) Nothing in clause (1) shall prevent Parliament from making any law giving, or authorising the giving of, any preference or making, or authorising the making of, any discrimination if it is declared by such law that it is necessary to do so for the purpose of dealing with a situation arising from scarcity of goods in any part of the territory of India. " THE first part of this Article is in terms an exception or a proviso to Art. 302 as is indicated by the non-obstante clause. This clause prohibits Parliament from making any law which would give any preference to one State over another or would make any discrimination between one State and another by virtue of the relevant entries specified in it. This clause prohibits Parliament from making any law which would give any preference to one State over another or would make any discrimination between one State and another by virtue of the relevant entries specified in it. In other words, in regard to the entries there specified, the power to impose restrictions cannot be used for the purpose of giving any preference to one State over another or making any discrimination in that manner. It is obvious that the reference to the Legislature of the State in this clause cannot be reconciled with the non-obstante clause; but the object of including the Legislature of a State appears to be to emphasise that like Parliament even the Legislature of a State cannot give any preference or make any discrimination. ( 45 ) SUB-ARTICLE (2) is an exception to sub-article (1) of Art. 303. It empowers the Parliament to make a law giving or authorising to give any preference or making any discrimination, but this power can be exercised only if it is declared by law made by the Parliament that it is necessary so to do for the purpose of dealing with a situation arising from scarcity of goods in any part of the territory of India; in other words, it is only when Parliament is faced with the task of meeting in emergency created by the scarcity of goods in any particular part of India that it is authorised to make a law making a discrimination, or giving preference, in favour of the part thus affected. ( 46 ) ON behalf of the States strong reliance is placed on the fact that Art. 303 (1) expressly refers to the entries relating to trade and commerce in any of the Lists in the Seventh Schedule, and it is urged that this gives a clear indication as to the scope of the provisions of Art. 301 itself. There is some force in this contention; but on the whole we are not prepared to hold that the reference to the said entries should govern the construction of Art. 301. The setting in which the said entries are referred to would of course determine the scope and extent of the prohibition prescribed by Art. 303 (1); but that cannot be pressed into service in determining the scope of Art. 301 itself. The setting in which the said entries are referred to would of course determine the scope and extent of the prohibition prescribed by Art. 303 (1); but that cannot be pressed into service in determining the scope of Art. 301 itself. It is significant that Art. 303 (1) does not refer to intercourse and in that sense intercourse is outside its sphere. It is likely that having authorised Parliament to impose restrictions by Art. 302 it was thought expedient to prohibit expressly the said power of imposing restrictions from being used for the purpose of giving any preference in so far as the relevant entries are concerned. It may also be that the primary object of confining the operation of Art. 303 (1) to the said entries was to introduce a corresponding limitation on the power of Parliament to discriminate under Art. 302. However that may be, in our opinion, the limitation thus introduced in Art. 303 (1) cannot circumscribe the scope of Art. 301 or otherwise affect its construction. Besides, as we will presently point out, there are other Articles in this Part which indicate that tax laws are included within Art. 301, and if that be so, the reference to the said entries in Art. 303 (1) cannot limit the application of Art. 301 to the said entries alone. ( 47 ) ARTICLE 304 reads thus : "notwithstanding anything in Art. 301 or Art. 303, the Legislature of a State may by law - (A) impose on goods imported from other States or the Union territories any tax to which similar goods manufactured or produced in that State are subject, so, however, as not to discriminate between goods so imported and goods manufactured or produced; and (B) impose such reasonable restrictions on the freedom of trade, commerce or intercourse with or within that State as may be required in the public interest : PROVIDED that no Bill or amendment for the purposes of clause (b) shall be introduced or moved in the Legislature of a State without the previous sanction of the President. " THE effect of Art. 304 (a) is to treat imported goods on the same basis as goods manufactured or produced in any State; and it authorises tax to be levied on such imported goods in the same manner and to the same extent as may be levied on goods manufactured or produced inside the State. We ought to add that this sub-article assumes that taxation can be levied by the State Legislature on goods manufactured or produced within its territory and it provides that outside goods cannot be treated any worse. How a tax can be levied on internal goods is, however, provided by Art. 304 (b ). The non-obstante clause referring to Art. 301 would go with Art. 304 (a), and that indicates that tax on goods would not have been permissible but for Art. 304 (a) with the non-obstante clause. This incidentally helps to determine the scope and width of the freedom guaranteed under Art. 301; in other words, Art. 304 (a) is another exception to Art. 301. ( 48 ) ARTICLE 304 (b) empowers the State Legislature to impose reasonable restrictions on the freedom of trade with other States or within its own territory. Again, the reference to the territory within the State supports the conclusion that Art. 301 covers the movement of trade both inter-State and intra-State. Article 304 (b) is to be read with the non-obstante clause relating to Art. 301 as well as Art. 303, and in substance it gives power to the State Legislature somewhat similar to the power conferred on the Parliament by Art. 302. The reference to Art. 303 in the non-obstante clause has presumably been made as a matter of abundant caution since the Legislature of a State has been included in Art. 303 (1 ). There are however, obvious differences in the powers of the Parliament and State Legislatures. The reference to Art. 303 in the non-obstante clause has presumably been made as a matter of abundant caution since the Legislature of a State has been included in Art. 303 (1 ). There are however, obvious differences in the powers of the Parliament and State Legislatures. In regard to an Act which the State Legislature intends to pass under Art. 304 (b) no bill can be introduced without the previous sanction of the President, and this requirement has obviously been inserted in order that regional economic pressures which may inspire legislation under the said clause should be duly examined in the light of the interest of national economy: such legislation must also be in the public interest which feature is common with the provision contained in Art. 302; such legislation must also satisfy the further test that the restrictions imposed by it are reasonable. That is an other additional restriction imposed on the powers of the State Legislatures. Thus there are three conditions which must be satisfied in passing an Act under Art. 304 (b), - the previous sanction of the President must be obtained the legislation must be in the public interest, and it must impose restrictions which are reasonable. It is of course true that if the previous sanction of the President is not obtained that infirmity may be cured by adopting the course authorised by Art. 255. The result of reading Art. 304 (a) and (b) together appears to be that a tax can be levied by a State Legislature on goods manufactured or produced or imported in the State and thereby reasonable restrictions can be placed on the freedom of trade either with another State or between different areas of the same State. Tax legislation thus authorised must therefore be deemed to have been included in Art. 301, for that is the obvious inference from the use of the non-obstante clause. ( 49 ) ARTICLE 305 saves existing laws and laws providing for state monopolies. It is unnecessary to deal with this Article. Its object clearly was not to interrupt or to affect the operation of the existing laws except in so far as the President may by order or otherwise direct. Article 306 is relevant. ( 49 ) ARTICLE 305 saves existing laws and laws providing for state monopolies. It is unnecessary to deal with this Article. Its object clearly was not to interrupt or to affect the operation of the existing laws except in so far as the President may by order or otherwise direct. Article 306 is relevant. It reads thus : "notwithstanding anything in the foregoing provisions of this Part or in any other provisions of this Constitution, any State specified in Part B of the First Schedule which before the commencement of this Constitution was levying any tax or duty on the import of goods into the State from other States or on the export of goods from the State to other States may, if an agreement in that behalf has been entered into between the Government of India and the Government of that State, continue to levy and collect such tax or duty subject to terms of such agreement and for such period not exceeding ten years from the commencement of this Constitution as may be specified in the agreement : PROVIDED that the President may at any time after the expiration of five years from such commencement terminate or modify any such agreement if, after consideration of the report of the Finance Commission constituted under Art. 280, he thinks it necessary to do so. " THIS Article has been subsequently deleted by S. 29 and Schedule to the Constitution (Seventh Amendment) Act, 1956, but its initial inclusion in Part 13 throws some light on the scope of Art. 301. Laws made by any State specified in Part B of the First Schedule levying any tax or duty on the import of goods into the State from other States or the export of goods from the State to other States were expressly saved by Art. 306 because it was realised that they would otherwise be hit by Art. 301. In other words, taxing statutes or statutes imposing duties on goods would, but for Art. 306, have attracted the application of Art. 301. ( 50 ) LET us now revert to Art. 301 and ascertain the width and amplitude of its scope. In other words, taxing statutes or statutes imposing duties on goods would, but for Art. 306, have attracted the application of Art. 301. ( 50 ) LET us now revert to Art. 301 and ascertain the width and amplitude of its scope. On a careful examination of the relevant provisions of Part 13 as a whole as well as the principle of economic unity which it is intended to safeguard by making the said provisions, the conclusion appears to us be inevitable that the content of freedom provided for by Art. 301 was larger than the freedom contemplated by S. 297 of the Constitution Act of 1935, and whatever else it may or may not include, it certainly includes movement of trade which is of the very essence of all trade and is its integral part. If the transport or the movement of goods is taxed solely on the basis that the goods are thus carried or transported that, in our opinion, directly affects the freedom of trade as contemplated by Art. 301. If the movement, transport or the carrying of goods is allowed to be impeded, obstructed or hampered by taxation without satisfying the requirements of Part 13 the freedom of trade on which so much emphasis is laid by Art. 301 would turn to be illusory. When Art. 301 provides that trade shall be free throughout the territory of India primarily it is the movement part of the trade that it has in mind and the movement or the transport part of trade must be free subject of course to the limitations and exceptions provided by the other Articles of Part 13. That we think is the result of Art. 301 read with the other Articles in Part 13.
