JUDGMENT NIKHIL NATH BHATTACHARJEE, J. 1. By an order dated 10th September, 1993 recorded in each of these cases, a learned Single Judge in Circuit at Port Blair referred these three matters to the Division Bench on the ground that questions of considerable importance including vires of Regulation were involved in these matters. Accordingly these three applications have been taken up by this Bench and heard together as the facts are almost same and identical questions of law are involved. This judgment and order shall therefore cover these three cases under consideration. 2. The petitioners have prayed for directions to the effect that the respondents were not entitled to retain the money illegally collected by them from the petitioners on the basis of Rule 29 of Andaman Excise Rules, 1934 read with notification dated 24th October, 1973. The petitioners have also challenged the notification dated 1st September, 1984 issued by the President of India promulgating the Andaman and Nicobar Islands (Amendment) Regulation, 1984 thereby amending the Andaman and Nicobar Islands Regulation III, 1876. The facts in short are as follows:- 3. The petitioner in C.O. No. 5188(W) of 1983 participated in a public auction to obtain a licence to vend various types of liquors, wines, beer etc. for the period from 1st April, 1974 to 31st March, 1975. He being the highest bidder was accepted by the respondent authorities and granted the licence for Middle Point, A & N Islands for the said period. He was also the highest bidder for two successive years and was granted the licence for the said purpose for the same area. The petitioner in C.O. 1622(W) of 1984 likewise was the highest bidder for some other area for each of the years from 1976 to 1979 and the petitioner in C.O. No. 15642(W) of 1984 similarly was the highest bidder and granted annual licences to sell liquor, wine and beer for certain other areas for the year 1977 to 1980. On the basis of the said licences the petitioners imported huge quantities of liquor from the mainland and sold the same through their respective shops for the areas the licences were given. 4. On 24th October, 1973, a notification was issued by the Chief Commissioner by virtue of powers conferred under Rule 29 of Andaman Excise Rules, 1934 prescribing the rates of excise duty payable by the licensees on India-made-Foreign-liquor and beer. 4. On 24th October, 1973, a notification was issued by the Chief Commissioner by virtue of powers conferred under Rule 29 of Andaman Excise Rules, 1934 prescribing the rates of excise duty payable by the licensees on India-made-Foreign-liquor and beer. Challenging the validity of the said levy another dealer, Jagannath of Middle Point, Port Blair filed a writ application before this Court whereupon a Civil Rule being no. 2903(W) of 1974 was issued. The said writ application was finally disposed of by Amiya K. Mookerji, J. who by his order dated 25th August, 1975 made the Rule absolute holding inter alia that excise duty being a tax levied on commodities produced or manufactured in the taxing state, and India-made-Foreign-Liquors and beer having already been subject to excise duty in the originating state, the authority in the Islands had no power to levy any excise duty upon them. The learned Judge further held that as the Regulation of 1876 under which the Excise Rules, 1934 was framed did not confer any power upon the Administration to impose any excise duty on India made Foreign liquors, Rule 29 of the Andaman Excise Rules 1934 which applies to country liquor as and when drawn from the bonded Warehouse situated in the Islands, was of no avail to the authorities to impose the duty. The respondent authorities preferred an appeal against the said order and judgment passed by Amiya Kumar Mookerji, J. and the Division Bench of the Court presided over by Murari Mohan Dutt, J. sitting with D.C. Chakraborty, J. in F.M.A.T. No. 328 of 1976 dismissed the appeal by an order and judgment dated 3rd May, 1978 confirming the said decision of the Learned Single Judge. 5. Before the Division Bench it was contended on behalf of the Appellant that the amount of excise duty that was deposited had been realised by the writ petitioner/respondent from his customers and did not belong to him and as such he was not entitled to get refund of the same. The contention was overruled and it was held that the administration cannot deprive a person of his property without the authority of law as provided under Article 31(1) of the Constitution. After the appeal was dismissed by the Division Bench, the entire amount so realised was refunded to the said writ petitioner/respondent, Jagannath. 6. The contention was overruled and it was held that the administration cannot deprive a person of his property without the authority of law as provided under Article 31(1) of the Constitution. After the appeal was dismissed by the Division Bench, the entire amount so realised was refunded to the said writ petitioner/respondent, Jagannath. 6. The present writ petitioners in view of the said judgment, findings and order of the trial Judge, as also of the Division Bench applied to the respondent authorities for refund of the sums illegally collected from them on the strength of the notification dated 24th October, 1973. But as no action was taken for a pretty long time, the present writ petitioner in C.O. 5188(W) of 1983 filed a writ petition being Civil Rule No. 29(W) of 1981 whereupon T.K. Basu, J. by an order dated 7th December, 1981 directed issuance of a writ of mandamus commanding the respondent authorities to consider the refund application and pass order thereon in accordance with law after giving the petitioner a chance of hearing. The said petitioner was thereafter directed to appear before the Deputy Commissioner, Excise for the purpose of hearing and it appears that by a letter dated 4th August, 1979 M.S. Malhotra, Assistant Secretary (Public) wrote to the Deputy Commissioner, Nicobar District, Car Nicobar for taking necessary steps for refund of the amount collected from him after verification. It was further communicated to the Deputy Commissioner that necessary refund bill after completing requisite formalities including verification of the Treasury vouchers nos. were to be sent to the Administration Secretariat for obtaining countersignature of the Chief Commissioner. Subsequently by a letter dated 4th August, 1980 the Deputy Commissioner, Car Nicobar informed the writ petitioner that the refund bill had already been forwarded to the Administration Secretariat for counter-signature. 7. Similarly in Civil Rule No. 7280(W) of 1980 Umesh Chandra Banerjee, J. directed to dispose of the pending refund application of the writ petitioner herein in C.O. No. 1622(W) of 1984 after taking note of the letter dated 24th February, 1974 written by Shri M.S. Malhotra, Assistant Secretary to the petitioner on behalf of the Chief Commissioner. Andaman and Nicobar Administration within a period of 4 weeks from the date of communication of the order. 8. Andaman and Nicobar Administration within a period of 4 weeks from the date of communication of the order. 8. In C.O. 15642(W) of 1984 the writ petitioner got a decree in Money Suit No. 12 of 1980 for recovery of the amount involved against the respondents and the concerned 1st Money Appeal No.12 of 1984 is being stayed before the learned District fudge, Andaman and Nicobar Islands though, however the entire decretal cost was deposited in court and is still lying in such deposit. 9. However before the countersignatures were made on the refund vouchers and the amounts of excise duties were withdrawn by the two petitioners herein, and the decretal cost could be proceeded against by the third petitioner herein, the Notification dated September 1, 1984 was issued by the President of India promulgating the Andaman & Nicobar Island (Amendment) Regulation, 1984 which imposed levy of excise duty retrospectively with effect from 24th October, 1973 on India made Foreign liquor notwithstanding any judgment, decree or order of any court thereby seeking to invalidate a valid judgment. Meanwhile by an order dated 3.7.1982 the Deputy Commissioner, Andaman District by referring to the decisions of the Supreme Court in AIR 1980 SC page 1037 and AIR 1976 SC page 1152 had come to the conclusion that the refundable amounts being excise duties collected from the Consumer public, the wine merchants should not be allowed to make an unjust enrichment by sums not being legally and equitably entitled to and the Administration being also not legally entitled to retain the same, such moneys, the order said, should be diverted for public and charitable purpose according to some scheme. Upon such conclusion the refund applications were rejected. Being aggrieved by the said decision and change in law with retrospective effect, which has been alleged to be ultra vires to Part III of the Constitution, the petitioners have come with the present writ applications. 10. In the original Regulation of 1876 there was no provision for imposition of any duty whatsoever on any liquor imported from the mainland. It was for the first time in 1934 that provision was made for imposition of excise duty on country liquor manufactured or produced in the island and for sale thereof. 10. In the original Regulation of 1876 there was no provision for imposition of any duty whatsoever on any liquor imported from the mainland. It was for the first time in 1934 that provision was made for imposition of excise duty on country liquor manufactured or produced in the island and for sale thereof. In respect of India-made-Foreign liquor, 1934 Rules provided only for obtaining licence by bidding in public auction for importation from the mainland and sale in the islands through sanctioned shops. Rule 29 of the said Rules read with the forms prescribed thereunder leave no room for doubt that excise duty was leviable only on country liquor and not India-made-Foreign liquor and the Calcutta High Court in the concurrent finding of the Trial Judge and Division Bench struck down the notification dated 24th October, 1973 which fixed rates of excise duty on India-made-Foreign liquor and been as scheduled in the said notification. 11. Against this background the impugned Regulation of 1984 which is set out below has to be read:- Ministry of Law, Justice and Company Affairs (Legislative Department) New Delhi, the 1st September, 1984/Bhadra 10, 1906 (Saka) The Andaman and Nicobar Islands (Amendment) Regulation, 1984. No. 2 of 1984 Promulgated by the President m the Thirty-fifth Year of the Republic of India. A Regulation further to amend the Andaman and Nicobar Islands Regulation, 1876. Whereas by reason of certain liquor not being manufactured or produced in the Union Territory of the Andaman and Nicobar Islands, countervailing duty is not leviable on such liquor which is imported into that territory. And whereas the consumption, except for medical purposes, of such liquor would be injurious to health and the levy of a special duty on the importation of such liquor into the Union Territory of the Andaman and Nicobar Islands would be an endeavour towards bringing about prohibition of the consumption as aforesaid of such liquor. Now, therefore, in exercise of the powers conferred by article 240 of the Constitution, the President is pleased to promulgate the following Regulation made by him. 1. Short title and commencement:- (1) This Regulation may be called the Andaman and Nicobar Islands (Amendment) Regulation, 1984.

ZAIL SINGH President R.V.S. Peri Sastri Secretary of the Government of India 12. Although these matters are pending from 1983 and despite several opportunities being given, the respondent authority has not chosen to file any affidavit-in-opposition in either of the three cases. Mention may be made that although the learned Government Pleader Mr. R. Shiv Saroop was present all through during the hearing of this case running for about 15 days before this Circuit Bench, he did not argue himself and Mr. N.N. Nag, learned Advocate on behalf of the respondents argued in the first two matters and Mr. Ashis Roy, learned Advocate in the third matter being C.O. 15642(W) of 1984 under instructions of the learned Government Pleader. Mr. S.C. Bose, learned Counsel on behalf of one of the writ petitioners submitted at the first place that the respondent authorities could not make any levy and collect excise duty on the strength of section 31A of the Regulation unless a notification., as mentioned in the said sub-section is issued fixing the rates of excise duty within the ceiling limit prescribed in the schedule appended thereto. His contention is that the provisions of s. 31A is an enabling provision which empowers the authority concerned to levy excise duty by a separate notification and unless such notification is issued the authorities cannot collect any excise duty. Mr. N.N. Nag, Learned Advocate for the respondent on the other hand submitted that the 1973 notification which prescribed some rates of excise duty should be read as the notification contemplated in Regulation 31A intending thereby to infuse life to a baby which is long dead, a proposition that baffles our comprehension. 13. Mr. N.N. Nag, Learned Advocate for the respondent on the other hand submitted that the 1973 notification which prescribed some rates of excise duty should be read as the notification contemplated in Regulation 31A intending thereby to infuse life to a baby which is long dead, a proposition that baffles our comprehension. 13. No notification as required under s. 31A has so far been issued. On a plain reading of s. 31A of the amended Regulation it appears that until and unless a notification is issued prescribing the rates at which the excise duty is to be realised, no excise duty can be levied or collected. The rates appended to the schedule of the said Section are only the ceiling limits of tax that can be levied in respect of items mentioned therein. The schedule circumscribes the authority of the executives to fix the rates of tax on individual items and in no case levying or realising at the maximum rate without issuing any Notification fixing the rates is contemplated by the legislature i.e. the President of India. The Explanation appended to the said newly inserted regulation makes the position more clear. The Explanation has been added to remove any doubt as to the effect of any such Notification which the Administrator is authorised to issue under this section and by not stretch of imagination it can be contemplated that the Notification to be issued, as referred to in the section, is the notification already in existence, a Notification which has already been struck down by the High Court. 14. Mr. S.C. Bose submitted, in the next place, that s. 31A of the Regulation of 1984 does not prescribe any assessment procedure nor machinery for assessment and does not contain any provision for appeal against such assessment thereby depriving the assessees of having the supervision by a Civil Court over the entire process of assessment and in such premises the same cannot be treated as a taxing statute. In support of his contention he has relied on a Judgment of the Supreme Court in K.P. Mupil Nayal vs. State of Kerala & another, AIR 1961 SC 552 , wherein the Supreme Court held that the assessment of tax must have to be made on a Judicial basis and unless the Act in question lays down the procedure to be followed in the matter of assessment and the machinery for assessment including the provisions for appeal are definitely stated, the Act will be liable to be declared ultra vires. It appears that neither any assessment procedure is laid down nor it contains any provision for appeal in case of dissatisfaction as to the assessment made and there is no assessment machinery prescribed in the Regulation and accordingly in view of the decision of the Supreme Court, s. 31A of the Regulation of 1984 has to be treated as ultra vires. 15. Mr. Bose's next submission is that Calcutta High Court declared the Notification dated 24th October, 1973 issued in exercise of power conferred by Rule 29 of the Andaman & Nicobar Excise Rule, 1934 illegal and ultra vires to Article 31(1) of the Constitution. But s. 31A read with s. 1, sub-section (2) lays down promulgation of the excise duty with retrospective effect treating the judgment and order of the High Court a nullity. He submitted that if any law is declared ultra vires to any of the provisions of Part III of the Constitution, under Article 13(2) of the Constitution the same is to be treated as valid and non est in the eye of law. Again, Notification or Rule which was void cannot be validated by any validation Act. It has to be re-enacted. In the instant case the President has not re-enacted with retrospective effect but has only amended and as a result the 1984 Regulation cannot validate the invalidity of the Rule or notification in question. In this connection, Mr. Bose has relied on the decision reported in D. Macropolo & Co. vs. Union of India, AIR 1972 Cal. In the instant case the President has not re-enacted with retrospective effect but has only amended and as a result the 1984 Regulation cannot validate the invalidity of the Rule or notification in question. In this connection, Mr. Bose has relied on the decision reported in D. Macropolo & Co. vs. Union of India, AIR 1972 Cal. 350 wherein Sabyasachi Mukherji, J. as His Lordship then was, sitting singly agreed with the Full Bench decision of the Delhi High Court in P.L. Mehra vs. D.R. Khanna, AIR 1971 Delhi 1 and following the decision of the Supreme Court in Deepchand vs. State of Uttar Pradesh, AIR 1959 SC 648 and Northern India Caterers Pvt. Ltd. vs. Union of India, AIR 1967 SC 1581 came to the conclusion that the statute which was void within the meaning of Article 13(2) of the Constitution is not existent for all purposes including repeal, amendment or enforceability. In short it was laid down that no void section can be made valid by an amendment. Here no re-enactment has been made. What has been made is amendment with retrospective effect in order that the relevant provision of the Excise Rule and the struck down Notification issued thereunder becomes valid and operative. The Apex Court did not countenance such approach and it follows therefore that such validating Regulation cannot validate the invalidity of the Rule or the Notification in question. 16. It is well settled that a legislature has the legislative competence to render ineffective the earlier judicial decisions by removing or altering or neutralising the legal basis in the unamended law on which such decisions were founded, even retrospectively. But, such power cannot be exercised to render ineffective the earlier judicial decisions by making a law which simply declares the earlier judicial decisions as invalid or not binding. For such power if exercised would not be a legislative power but a judicial power which cannot be encroached upon by a legislature under the Constitution of India. This is the consistent view of the Supreme Court. Mr. A.S. Roy the learned Advocate for one of the writ petitioners in this connection has cited the decision of the Supreme Court in State of Haryana vs. Kamal Co-op. Farmers Society Ltd. & other, AIR 1994 SC 1 wherein the Supreme Court has considered its earlier decisions on this point and declared the law as stated above. 17. Mr. A.S. Roy the learned Advocate for one of the writ petitioners in this connection has cited the decision of the Supreme Court in State of Haryana vs. Kamal Co-op. Farmers Society Ltd. & other, AIR 1994 SC 1 wherein the Supreme Court has considered its earlier decisions on this point and declared the law as stated above. 17. In this case, as herein before held, the provision of s. 31A of the Regulation is invalid and ineffective. But, s. 6(1) of the said amendment Regulation of 1984 simply declares that the levy of excise earlier made on the basis of the earlier law are not to be deemed to be invalid and on the contrary the same should be treated as validly assessed or collected in accordance with law. On the basis of the law as stated above the provision of s. 6(1) in substance amounts to declaring earlier judicial decisions as invalid and not binding upon the authorities and hence must be held to be invalid as amount to encroachment upon the judicial power by the legislature of the state and accordingly the same is ultra vires to the Constitution of India as held by the Supreme Court in the case of State of Haryana vs. Kamal Co-op. Society (supra). 18. The next submission of both Mr. Bose and Mr. Roy was that s.6(2) of the Amended legislation that those who have got the refund will not be affected, but those who have not got the refund in terms of the order of the High Court would be affected and would not get the refund amounts to a clear discrimination. Persons concerned who paid excise duty under a mistake will form one particular class and those who have been refunded would form another class has no logic or reasonableness and is arbitrary and discriminatory. 19. In Jalan Trading Co. vs. Mill Mazdoor Sabha, AIR 1967 SC 691, the Supreme Court declared the provisions of s. 34(2) of the Payment of Bonus Act, 1965 discriminatory and violative of Article 14 of the Constitution. The reason was that although the Act was validly passed for giving minimum bonus irrespective of loss but it provided that the Act would not be applicable to the cases in respect of which industrial disputes were pending immediately before May 29, 1965, the date of promulgation of the Act. The reason was that although the Act was validly passed for giving minimum bonus irrespective of loss but it provided that the Act would not be applicable to the cases in respect of which industrial disputes were pending immediately before May 29, 1965, the date of promulgation of the Act. It was held that the classification on such basis was not reasonable and as such the same was held to be arbitrary and discriminatory. The provisions of s. 6(2) of the Amendment Regulation must also be held to be discriminatory and violative of Article 14 of the Constitution on the same reasoning of the Supreme Court. Accordingly, it is held that the provisions of s. 6(2) of the amending Regulation is ultra vires of Article 14 and is void as in our view there is no scope for making discrimination in respect of persons who had paid the excise duty under mistake of law, but have taken refund and those who paid but have not got refund even though the imposition and collection having already been declared illegal and inoperative. In the aforesaid decision the Supreme Court also considered the case of Shib Sankar Dal Mills vs. State of Haryana, AIR 1980 SC 1037 wherein the Supreme Court observed that where public bodies recover people's money, later discover to be erroneous levy, the Dharma of the situation admits of no equivocation. And further that there is no law of limitation especially for public body for virtue of returning what was wrongfully recovered from whom it belonged. In this connection, provisions of Article 265 of the Constitution of India may be referred to. In this Article it is provided that tax shall be levied or collected only under the authority of law. According to the constitutional provision, not only levies but also collection of tax must be under the authority of law. 20. In the instant case, the right to get refund has been adjudicated and approved finally by this Court. Many dealers took back their money, but the writ petitioners have been denied the benefits. The Division Bench held that the excise duty liable to be refunded was the property of the dealers within the meaning of Article 31(1) of the Constitution of India. Article 31 is no longer there in the Constitution. Many dealers took back their money, but the writ petitioners have been denied the benefits. The Division Bench held that the excise duty liable to be refunded was the property of the dealers within the meaning of Article 31(1) of the Constitution of India. Article 31 is no longer there in the Constitution. But when the right to get refund accrued, Article 31 was in force, and, thus, not only the collection becomes illegal, but also the denial to refund the property of the persons from whom collected without authority of law becomes illegal and also unconstitutional. 21. It is to be noted as already pointed out by us that retrospective amendment cannot validate the invalid levy and collection, and also cannot take away the force of the judgment already rendered on the basis of which the right to return accrued. 22. A point was raised on behalf of the respondents that the writ court being the court of equity should not allow the refund which will amount to unjust enrichment. In support of this contention reliance was placed on the decision of the Supreme Court in the case of State of Madhya Pradesh vs. Vyankatlal, AIR 1985 SC 901 as also in the case of Shib Sankar Dal Mills vs. State of Haryana (supra). In the first case the Supreme Court observed that the burden of paying the amount in question had been transferred by the respondents to the ultimate purchasers and, therefore, the respondents were not entitled to get the refund and instead the persons on which lay the ultimate burden to pay the amount would be entitled to get refund of the same. But as the persons who actually paid the amount could not be identified, the amount deposited was to be utilised for the purpose for which the Fund was created, namely, development of sugarcane. There is no question of refunding the amount to the respondents who had not eventually paid the amount towards the Fund. Doing so would virtually amount to allowing the respondents an unjust enrichment, said the Supreme Court. 23. In this case sugar was declared as an essential commodity and a notification was issued by the Government under the relevant Sugar Control Order fixing ex-factory prices for different sugar factories. The supply price was a little higher than the ex-factory price. Doing so would virtually amount to allowing the respondents an unjust enrichment, said the Supreme Court. 23. In this case sugar was declared as an essential commodity and a notification was issued by the Government under the relevant Sugar Control Order fixing ex-factory prices for different sugar factories. The supply price was a little higher than the ex-factory price. The difference between the supply price and the ex-factory price was being deposited to the Madhya Pradesh Government sugar fund. The Government made several demands from the respondent-proprietors to credit the differences to the fund and the respondents ultimately deposited Rs. 50,000/- under protest. In the opinion of the High Court the State had levied and collected under the purported legal authority certain sum for which it has no legislative competence to do, and, therefore, the State must restore the same to the persons from whom it collected and cannot keep the same and further that the persons who could claim the same was corresponding purchasers. The Supreme Court held that the High Court omitted to decide the question whether a particular purchaser could recover thereafter from the respondents whatever excess collection had been made. On the question of refund of the amount in dispute the Supreme Court made the observations quoted above. 24. In Shib Sankar Dal Mill's case (supra) the dealers paid the market fees at the increased rate of 3% raised from original 2%. The excess of 1% over the original rate having been declared ultra vires, the whole amount became refundable to the dealers from whom it was recovered by the market committee concerned. The Market Committee contended that the excess collection actually belonged to the purchasers upon whom the burden had been shifted. The Supreme Court held that the procedure adopted in AIR 1976 SC 1152 in a similar situation must usefully be adopted and the scheme of refund by the Market Committee and redistribution to the next purchasers according to their claims had to be framed. 25. In both the cases there were definite and cogent materials to suggest that the amounts that had been illegally collected ultimately descended upon the consumers and in case such consumers could not be fixed up, a scheme for public utilisation of the amounts could be brought of. 25. In both the cases there were definite and cogent materials to suggest that the amounts that had been illegally collected ultimately descended upon the consumers and in case such consumers could not be fixed up, a scheme for public utilisation of the amounts could be brought of. There were in both the cases definite and cogent materials to show that the amounts had been collected as such from the ultimate consumers. 26. In the instant case there is absolutely no material to show whether the excise duty that was paid in advance upon mistake of law was consumed by the dealers from their margin of profits or not. It is nobody's case that the excise duty was recovered as such from the purchasers by the wine merchants. The dealership was obtained through public auction staking high amounts. No price control order fixing the price of India made Foreign liquor or beer was there. It was purely a question of contract involving high risk when the dealerships were obtained. The merchants were allowed a freehand in the matter of fixation of price and in so fixing the price there is no knowing how much of the duty paid in advance if at all was added up in the selling price. In the circumstances, in our opinion there cannot be any illegal enrichment if the amounts collected are refunded, rather, in our view, illegal enrichment, if any, is on the side of the State Administration if they are allowed to retain the collections instead of refunding to the dealers, who definitely paid the amounts and does not appear to have shifted the same separately upon the consumering public. 27. Considering all the aspects of the matter we are of the opinion that this case does not call for either to refuse the claim for refund or for evolving a scheme for redistribution of the amount paid through mistake of law. 28. In so far as the question of limitation is concerned, the plea of limitation has not been taken by any affidavit-in-opposition. However, even in the absence of the plea of limitation this point has been raised. The Supreme Court in the Shib Sankar Dal Mills vs. State of Haryana, AIR (supra) held that there is no law of limitation, especially for public body for the virtue of returning what was wrongfully recovered to whom it belonged. However, even in the absence of the plea of limitation this point has been raised. The Supreme Court in the Shib Sankar Dal Mills vs. State of Haryana, AIR (supra) held that there is no law of limitation, especially for public body for the virtue of returning what was wrongfully recovered to whom it belonged. The Supreme Court in the case of Sales Tax Officer vs. Kanhaiya, AIR 1959 SC 135 held that a mistake under s. 72 of the Indian Contract Act can be a mistake of law as well as a mistake of fact. Whatever it may be, the limitation of three years must start from the date of knowledge of such mistake. In the instant case the petitioners applied to the administration for refund of the respective amount within the period of three years from the date of discovery of mistake and filed a suit for recovery of the amount or Writs of Mandamus with directions upon the Islands Administration to pay the amounts. Furthermore, applications for refund were submitted long before the Amending Regulation came into force and that being the position the question of limitation does not and cannot arise. There is no question of waiver or estoppel applicable in this case, either. 29. In the result, in the view we have taken, the writ petitions succeed and the following reliefs are granted:- (a) Section 31A of the Andaman & Nicobar Islands (Amendment) Regulation, 1984 is declared to be ultra vires to Article 14 of the Constitution of India. (b) Section 6(1) and s. 6(2) of the said Regulation are also declared to be ultra vires as it is repugnant to the Constitution of India. Section 6(2) is declared ultra vires also of Article 14 of the Constitution of India. Both the sections are hereby struck down. 30. The Rules are made absolute. 31. Let a Writ in the nature of Mandamus be issued commanding the respondents to cancel and/or withdraw the impugned order of rejection dated September 1, 1984 passed by the respondent No.3 being Annexure to the first two writ petitions and to refund to the said writ petitioners the money illegally collected from them within a period of two months from the date. In respect of C.O. 15642(W) 1984, the learned District Judge is directed to proceed with the appeal, namely, Money appeal arising out of Money Suit No. 12 of 1980 in the light of our decision. 32. On the prayer of the Learned Advocate appearing for the Respondents, there shall be a stay of operation of this order for a period of two months from date. 33. There shall be no order as to cost. I agree. Petitions allowed.
