SARJOO PROSAD, C. J. : This is an application under Art. 226 of the Constitution of India in which the petitioners have prayed for a writ of prohibition or mandamus or any other appropriate writ preventing the respon­dents from proceeding with a reference under section 10(l)(c) of the Industrial Disputes Act made to the Industrial Tribunal. The petitioners are Rivers Steam Navigation Co. Ltd. and India Gene­ral Navigation and Railway Co. Ltd. They may be compendiously described as Joint Steamer Com­panies. The allegations of fact on which the peti­tion is founded are these: (2) The petitioners state that during all mate­rial times uptil 30th June 1956, one S. C. Dutta acted as their labour contractor at KarimganJ Steamer Ghat. The relationship between S. C. Dutta and the petitioners was governed by an agreement, the terms whereof have been embodi­ed in a document dated 31-8-1938 signed by the Managing Agents of the petitioners on the one hand and S. C. Dutta on the other. It is stated that under the terms of the agreement, the con­tractor S. C. Dutta employed various persons for handling cargoes at Karimganj Steamer Ghat and the persons so employed by S. C. Dutta worked under the latter and were not the employees of the petitioners. The case of the petitioners is that these em­ployees were paid by the said contractor and the petitioners had nothing to do with them. It is said that it was the contractor who had the authority for fixing the hours of work and for granting or re­fusing leave to such workers. He had also the power to suspend, discharge or dismiss these wor­kers and to do whatever he liked with the employment or non-employment of those persons. The petitioners had nothing to do with them and whatever service was rendered to the petitioners by these workers was rendered through S. C. Dutta who was an independent contractor and employed these persons for the purpose of executing the agreement which he had entered into with the petitioners. (3) On the 30th May 1956 the Government of Assam issued a notification No. GLR. 232/56 under which it purported to refer an industrial dispute between the said S. C. Dutta, labour contractor and the workmen of Karimganj Steamerghat repre­sented by Karimganj Dock Mazdoor Union to the adjudication of Sri Radhanath Hazarika respon­dent No. 1, who was then the Judge of the Indus­trial Tribunal. 232/56 under which it purported to refer an industrial dispute between the said S. C. Dutta, labour contractor and the workmen of Karimganj Steamerghat repre­sented by Karimganj Dock Mazdoor Union to the adjudication of Sri Radhanath Hazarika respon­dent No. 1, who was then the Judge of the Indus­trial Tribunal. The matters in dispute have been specified in the notification and they refer to maundage rates of handling cargoes, the sort of housing and medical facilities and leave rules to which the workers claim to be entitled and the arrangement if any, that should be made by the contractor for the improvement of housing and medical facilities and introduction of leave rules and pay of the chowkidars. A copy of the notification in question is an annexure to this petition. S. C. Dutta, the labour contractor was a party to the proceedings before the said Tribunal on the terms of the reference. It appears however that the Tribunal issued a notice on the petitioners directing them to file their written statements. The petitioners protest­ed against this notice on the ground that they were not parties to the reference and the Tribunal had no jurisdiction to require the petitioners to file any written statement in that proceeding. This plea prevailed with the Tribunal. In the meantime, on 30-6-1956, S. C. Dutta died. The case of the petitioners is that although they had not issued any formal letter of appoint­ment to his son Sunirmal K. Dutta, yet Sunirmal Dutta had taken Over charge of the work of the contract of his late father and that he was already working under them as such. They actually sent a letter of appointment to Sunirmal Dutta on the 27th .July, 1956 purporting to confirm his appoint­ment as contractor with effect from the 1st of that month on the same terms as contained in the con­tract dated 31-8-1938 between the petitioners and the late S. C. Dutta. According to the petitioners Sunirmal Dutta accepted this letter of appoint­ment intimation whereof was received by them on the 9th August 1956. Then it appears that on the 16th July 1956, the Joint Secretary of Karimganj Dock Mazdoor Union wrote to the Labour Officer, Cachar sug­gesting that the workmen who were employees of the petitioners should be directly employed under them and that there should be no contractor or middleman in between. Then it appears that on the 16th July 1956, the Joint Secretary of Karimganj Dock Mazdoor Union wrote to the Labour Officer, Cachar sug­gesting that the workmen who were employees of the petitioners should be directly employed under them and that there should be no contractor or middleman in between. This led to a concilia­tion proceeding in which the petitioners refused to appear. Meanwhile on 11-8-1956, the Govern­ment of Assam issued a fresh notification amend­ing the earlier one and adding the management of the petitioners as a second party to the dispute referred to the Industrial Tribunal by virtue of their notification dated 30-5-1956. In the later notification it was stated that since the labour contractor had died and no new contractor had been appointed in his place, in par­tial modification of the earlier notification, Gov­ernment directed that the management of the peti­tioners Company should be impleaded as a party to the proceeding. This was followed by another notification on 4-9-1956. As the terms of this notification have assumed some importance on the arguments, it is as well to reproduce it here: "No. GLR. 232/56. In supersession of this Department Notification No. GLR. 232/56 dated 11-8-1956 the Governor of Assam is pleased to order the following: 1. Add (i) The Management of R. S. N. and I. G. N. Rly. Go. Ltd Knrimgani and (ii) Shri Sunirmal K. Dutta, new Labour Contractor C/o. Sub-Agent. R. S. N. and I. G. N. and Rly. Co. Ltd. Karimgani as the 2nd party to the dispute. 2. Add the following as issue No. (e) in the Schedule to this Department Notification No. G.L.R. 232/56 dated 30th May, 1956. (e) Is the Union justified in its demand for abolition of the post of Labour Contractor and direct employment of workers by the Company?" (4) The petitioners challenge the above noti­fication and contend that the Government had no jurisdiction to make any such reference impleading the petitioners as parties to dispute when neither in fact nor in law any such dispute existed between the petitioners and the workmen in ques­tion. The whole case of the petitioners on this point is, as it has been stated earlier, that these workmen were working under the labour con­tractor who was an independent contractor and these workmen were therefore employees not of the petitioners but of the contractor and there was no contractual nexus between the workmen and the petitioners' management. Government therefore had no jurisdiction to implead as parties to a dispute the petitioners who had no concern with the dispute in question. In support of this argument, the petitioners have relied upon the terms of the agreement entered into bet­ween S. C. Dutta on the one hand and the peti­tioners on the other. This agreement is dated 31-8-1938. Mr. Das on behalf of the petitioners has invited our attention to the various terms of this, document in order to show to us that no contractual relationship existed between the petitioners and the workers. The workers on the contrary have averr­ed, as it appears from the affidavit in opposition filed by one Rajgir Singh, the Joint Secretary of the Karimganj Dock Mazdoor Union, that the status of the contractor S. C. Dutta, deceased, was that of a mere commission agent of the petitioners Com­pany and that the wages of the workmen paid every month from the funds of the Company; they were paid according to scheduled rate fixed by the Company and the Company used to make good the-deficiency if the workers, at the maundage rates, could not earn the guaranteed minimum of Rs. 45/-- per month each, as fixed by the Company. The workers contend that the contractor only got as his remuneration a commission at the rate of half anna per rupee on the total monthly bill of wages of the workmen and the appointment, dis­missal, discharge and other conditions of service of the workmen were in the hands of the petitioners Company, though made through the contractor; the rent-free 'housing' of the workmen, which form­ed a part of their wages, had to be provided by the Company and was its direct responsibility. Therefore according to them they did not recognize S. C. Dutta as their employer and they never accept­ed the position that they were not employed by the petitioners Company. Therefore according to them they did not recognize S. C. Dutta as their employer and they never accept­ed the position that they were not employed by the petitioners Company. It is to be remembered that whatever the nature of the contract may be between the petitioners and S. C. Dutta, the work­men were not parties to the contract and the matter whether the workmen are really employees of the petitioners - the Joint Steamer Companies or em­ployees of the contractor will have to depend upon-a consideration of the evidence in the case. The decision of the point does not rest merely on the construction of the agreement dated 31-8-1938. It is therefore too early to say at this stage that there was no dispute between the petitioners, and the workmen and therefore Government had no authority to refer any such dispute for the deci­sion of the Industrial Tribunal. We desire to say as little as possible on this point lest it might prejudice the merits of the claims put forward by the respective parties. This would be a matter on which the Industrial Tribunal itself is called upon to pronounce after taking in view the evidence (adduced in the case. We are therefore unable" for entertain the contention of Mr. Das that there was no industrial dispute within the meaning of the law which could form the basis of a valid reference under S. 10 of the Industrial Disputes Act. In our opinion the notification issued by the Government on 4-9-1956 making the petitioners a party! to the dispute therefore could not be attacked on this ground. (5) The second contention of Mr. Das is that once having made a reference tender S. 10 of the Industrial Disputes Act, the Government had no authority to make any changes or modifications to the said notification. The learned counsel points out that in the earlier notification making the refer­ence the dispute was confined merely to the work­men on the one hand and the contractor on the other. He submits that on the terms of the notifi­cation dated 4-9-1956 it appears that Government had superseded the earlier notification dated 11-8-1956. He contends that this supersession could not be possible under S. 10 of the Industrial Disputes Act Or any other provision of the law; and inas­much as Government purported to issue a noti­fication of this kind, the notification is invalid. He contends that this supersession could not be possible under S. 10 of the Industrial Disputes Act Or any other provision of the law; and inas­much as Government purported to issue a noti­fication of this kind, the notification is invalid. In support of his contention the learned counsel has relied upon a decision in D. N. Ganguly v. State of Bihar, AIR 1956 Pat 449 . It was held in that case that though under S. 10(2) and the pro­viso to S. 10(1) of the Industrial Disputes Act Government are empowered to make a reference in their discretion, yet where a dispute exists, there is statutory obligation on the Government to make such a reference provided the conditions prescrib­ed are satisfied. It was also held there that there was no ex­press provision either under S. 10 or any other section of the Act empowering the State Govern­ment to withdraw a reference after once it had been validly made to the Industrial Tribunal. Re­liance was placed on S. 21 of the General Clauses Act in support of the argument that the State Government had implied power of revoking the reference. It was argued that the authority having the power to make a reference had also the power to revoke the same. This contention was overruled by the two learned Judges on the ground that S. 10 imposed a statutory duty on the Government to make a reference provided a dispute existed and once a reference has been made then S. 21 of the General Clauses Act could not be invoked to support the contention that Government could of their own accord withdraw the reference which they had already made; then the reference made under S. 10 of the Industrial Disputes Act had to take its course as required by the law. The observa­tions in this judgment therefore, in my opinion, do not support the contention of Mr. Das that it was not open to the State Government even to modify "the notification which they had made earlier im-pleading the petitioners as a party to the dispute. Mr. Das in particular relies upon a passage in the -judgment of Das C J., as he then was, where his Lordship observes thus: "Speaking personally, I think that it will depend on the nature of the amendment, etc. Mr. Das in particular relies upon a passage in the -judgment of Das C J., as he then was, where his Lordship observes thus: "Speaking personally, I think that it will depend on the nature of the amendment, etc. My 'learned brother has referred to certain other pro­visions of the Industrial Disputes Act, and I do not think that the power of amendment, etc., given by Sec. 21. General Clauses Act can be so used as to nullify the other provisions of the Industrial Dis­putes Act." His Lordship does not hold that in no case an amend­ment is possible. All that he says is that no such amendment would be permissible so as to nullify the provisions of the Industrial Disputes Act. Mr. Das has been unable to point out to us that by the amendment in the instant case any of the provi­sions of the Industrial Disputes Act have been nullified. He referred to S. 10 of the Act and the •proviso thereunder, to support his contention; but in our opinion the justification for the amendment would follow from the terms of S. 10 itself. Mr. Das concedes that it was open to Govern­ment to make a fresh reference if it thought that a dispute existed between the petitioners on the one hand and the workmen on the other. This could be done under S. 10 of the Act. If this was ^possible and if the same Tribunal could proceed to deal with the matter, as the learned counsel concedes, even simultaneously, I am unable to see why the amendment, by virtue of that power, could not be permitted. The power to make the amendment of the nature with which we are con­cerned in the present case therefore flows from S. 10 itself; because if in a given case by some mistake or oversight a person or a party whose presence was necessary for a proper adjudication of the industrial dispute is not made a party, then it would be the clear duty of the Government making a reference under S. 10, to make such a person a party to the dispute, even by a subse­quent notification. Otherwise the reference itself would be rendered infructuous and the duty or the obligation which the statute imposes upon the Government would not be carried out. Otherwise the reference itself would be rendered infructuous and the duty or the obligation which the statute imposes upon the Government would not be carried out. For this reason we have no doubt that Govern­ment had the power on the terms of S. 10 of the Industrial Disputes Act itself read with S. 21 of the General Clauses Act to make the proposed amendment. Indeed that this was a matter of mere form and not of substance has been recognized by a decision of the Madras High Court in South India Estate Labour Relations Organization v. State of Madras. (S) AIR 1955 Mad 45 . Venkatarama Aiyar J., as he then was, who delivered the judgment in that case held that the objection that Government had no jurisdiction to amend a reference made under S. 10 of the Industrial Disputes Act is one of form and not of substance. It were open to Government to make under S. 10 an independent reference concerning any matter not cleared by the previous reference, the fact that it took the form of an amendment to the existing reference and not an additional reference was a mere technicality which did not merit any consideration. I should think that sub-sec. (5) of S. 10 or sub-s. (5) of S. 20 which though in terms may not be applicable to an amendment of this character, do in addition support the inference that such an amendment would be permissible in law to give effect to the provisions of the statute. This contention also therefore in our opinion does not carry conviction. (6) The next argument advanced by Mr. Das is that the new issue which has been framed under the notification in question, i. e., "is the Union justified in its demand for abolition of the post of Labour Contractor and direct employment of Workers by the Company," does not fall under Industrial Dispute at all; and therefore such an issue could not be referred for adjudication to the Industrial Tribunal. He refers in this context to S. 7A(1) of the Act as it now stands. He refers in this context to S. 7A(1) of the Act as it now stands. It is provid­ed there that the appropriate Government may, by notification in the Official Gazette, constitute one or more Industrial Tribunals for the adjudica­tion of industrial disputes relating to any matter, whether specified in the Second Schedule or the Third Schedule; and he refers to the various items specified in those schedules to support his conten­tion that an issue of this character seeking for abolition of the post of a contractor does not fall under any of the items enumerated in either of the schedules. It appears to me however that it is unneces­sary to go to the schedules for this purpose because an issue of this kind should be covered by the defi­nition of 'industrial dispute' as given in S. 2(k) of the Act. 'Industrial dispute' as defined in the Act means any dispute or difference between employer and employees, which is connected with the employ­ment or non-employment or the terms of employ­ment or with the conditions of labour of any per­son. Whether the workmen should work directly) under the petitioners or through the agency of a I contractor is a matter connected with the employment or terms of employment or conditions of ' service of these workmen and it cannot be said ' that such a matter does not fall at all within the purview of 'industrial dispute'. Mr. Lahiri con­tends that the issue may well come under item 1 of the Third Schedule - "Wages, including the period and mode of payment"' - because according to him the contention of the workmen is that the contractor takes a share out of the wages payable to these petitioners, the workmen, which the work­men do not approve of. Whatever the position may be, we are at this stage not prepared to go into these disputed ques­tions of fact; but it seems to us that on the defi­nition of the term 'industrial dispute" itself we are unable to hold that an issue of this kind is alto­gether precluded from consideration. Mr. Lahiri has also referred to a decision in 'Western India Automobile Association v. Industrial Tribunal, Bom­bay, AIR 1949 F. C. 111. Mr. Lahiri has also referred to a decision in 'Western India Automobile Association v. Industrial Tribunal, Bom­bay, AIR 1949 F. C. 111. It was held there that "the words 'employment and non-employment" in the definition of industrial dispute in S. 2(k) are of widest amplitude and have been put in juxtaposition to make the definition thoroughly comprehensive. The words 'in connection with" further widen the scope of the dispute and do not restrict it by any means. 'Any dispute connected with employment or non-employment' would ordi­narily cover all matters that require settlement between workmen and employers, whether those matters concern the courses of their being out of service or any other question and it would also include within its scope the reliefs necessary for brining about harmonious relations between the employers and the workers." It should also be pointed out that the reference made by the Government is on the authority of S. 10 of the Industrial Disputes Act and that section provides that where the appropriate Government is of opinion that any dispute exists or is apprehend­ed, it may by order in writing refer the dispute or any matter appearing to be connected with or relevant to the dispute to a Tribunal for adjudi­cation. These words in our opinion are of sufficient amplitude to cover an issue of this character. We are therefore unable to entertain the contention of Mr. Das that the State Government had no juris­diction to refer the issue mentioned in the notifi­cation dated 4-9-1956 for adjudication by the In­dustrial Tribunal. (7) Mr. Das further drew our attention to cer­tain averments in the petition which are to the effect that section 10 of the Industrial Disputes Act is ultra vires Arts. 14 and 19(l)(g) of the Consti­tution of India; but the learned counsel very frank­ly conceded that ho was not prepared to urge the contention in that extreme form. (7) Mr. Das further drew our attention to cer­tain averments in the petition which are to the effect that section 10 of the Industrial Disputes Act is ultra vires Arts. 14 and 19(l)(g) of the Consti­tution of India; but the learned counsel very frank­ly conceded that ho was not prepared to urge the contention in that extreme form. The point appears to have been dealt with in a recent judg­ment of the Supreme Court in 'Niemla Textile Finishing Mills Ltd. v. 2nd Punjab Tribunal, (S) AIR 1957 SC 329 , where it was held that "having regard to the provisions of the Act it is clear that S. 10 is not discriminatory in its ambit and the appropriate Government is at liberty as and when the occasion arises to refer the industrial disputes arising or threatening to arise between the: employers and the workmen to one or the other of the authorities according to the exigencies." It is obvious that no two cases are alike in their nature and the industrial disputes which arise or are apprehended to arise in a particular establish­ment or undertaking, have to be treated with reference to the situation prevailing in the same. Therefore the Deference to one or the other of the authorities has necessarily got to be determin­ed in the exercise of its best discretion by the Government. Such discretion is neither unfettered nor uncontrolled because the criteria for the exer­cise of such discretion are indicated in the terms of the Act itself. Mr. Das urges that if the power to make an amendment is read in S. 10 of the Act, then it would be obviously concerning an un­reasonable discretion to the State Government to discriminate. We are unable to accept this conten­tion. There is no warrant for the assumption as pointed out by the Supreme Court in that case that the discretion given to the State Government under S. 10 will be exercised by the Government arbi­trarily Or capriciously so as to prejudice the inter­ests of any of the parties concerned. It must be therefore held that S. 10 of the Act cannot be held to be constitutionally void as infringing the provisions of Arts. 14 and 19(l)(f) and (g) of the Constitution. It must be therefore held that S. 10 of the Act cannot be held to be constitutionally void as infringing the provisions of Arts. 14 and 19(l)(f) and (g) of the Constitution. (8) In the view which we take of the various points urged by the learned counsel for the peti­tioners, it is unnecessary for us to deal with the arguments of the learned Advocate General that the application is defective in that the Industrial Tri­bunal has been constituted afresh and that the present member of the Tribunal is not a party to the application. We think that there is no sub­stance in this application which is accordingly-rejected and the rule is discharged. The respon­dents are entitled to their costs; hearing fee Rs. 100/-. (9) DEKA, J. : I agree. Rule discharged.
