Kolah	 J. B. Dadachanji	 O. C. Mathur and Ravinder Narain	 for the appellant. section V. Gupte	 Additional Solicitor General of India	 K. T. Sule	 M. C. Bhandare	 M. Rajagopalas and K. B. Chaudhuri	 for the respondents. May 9. The judgment of the Court was delivered by GAJENDRAGADKAR.J. These 16 appeals arise out of petitions filed by the 16 respondents who arc the employees of the appellant	 the Bombay Gas Co. Ltd.	 under section 33C (2) of the Industrial Disputes Act (No. 14 of 1947) (hereinafter called the Act). These respondents are the District Siphon Pumpers and Heat Appliances Repairers Inspectors	 and in their applications made before the Second Labour Court	 Bombay	 they alleged that as a result of the award made by the Industrial Tribunal in reference (I. T.) No. 54 of 1949 published in the Bombay Government Gazette on May 11	 1950	 they were entitled to a certain benefit 712 and they moved the Labour Court to compute that benefit in terms of money and to direct the appellant to pay the same to them. The direction in the earlier award on which this claim was based was made in these terms "The demand in respect of the workers of the Mains	 Services and District Fittings Departments and Lamp Repairers and others who were till 1948 required to work on Sundays and in respect of whom a weekly day off was enforced thereafter without any corresponding increase in wages is granted. In respect of the rest	 the demand is rejected. This demand was resisted by the appellant on several preliminary grounds which formed the subject matter of several preliminery issues framed by the Labour Court. The principal contentions raised by the appellant by way of preliminary objections were. that the applications made by the respondents were not maintainable under section 33C (2) of the Act and that the said applications were barred by res judicata by reason of awards made in other proceedings between the same parties. It was also urged by the appellant that if the claim made by the respondents was held to be justified by the direction of the award on which the respondents relied	 then the said direction was given by the earlier Tribunal without jurisdiction and as such	 was incapable of enforcement. On the construction	 the appellant urged that the said direction did not cover the cases of the respondents	 and it was argued that even if the said direction was held to be valid and it was also held that it gave the respondents the right to make the present claim	 the conditions precedent prescribed by the said direction had not been satisfied by any of the respondents	 and so	 on the merits	 their claim could not be sustained. 713 The Labour Court took up for trial 10 prcliminary issues in the first instance and by its judgment delivered on June 3	 1961	 it rejected all the preliminary pleas raised by the appellant. In other words	 the preliminary issues framed by the Labour Court were found in favour of the respondents. Thereafter	 the applications were set down for hearing on the merits and evidence was led by both the parties in support of their respective claims. On considering the evidence	 the Labour Court came to the conclusion that the respondents had established their claims	 and so	 it has directed the appellant to pay to the respondents the respective amounts specified against their names in the award. The plea raised by the appellant that the whole of the: claim made by the respondents should not be allowed on the ground of belatedness and laches	 was	 according to	 the Labour Court	 not sustainable under section 33C (2). That is why the Labour Court computed the benefits claimed by the respondents in terms of money from the date when the earlier award became enforceable until the date of the present applications filed before it. The appellant has come to this Court by special leave against the preliminary decision and the final order passed by the Labour Court in favour of the respondents. Before dealing with the points raised in the present appeals by the appellant	 it is necessary to set out briefly the terms of the earlier award on which the respondents ' claims are based. In the previous industrial dispute	 the employees of the appellant had made several demands. In the present case	 we are concerned with demand No. 11. This demand was made in these terms "(a) Workers should get a paid weekly off. (b) Weorkers of Mains	 Services and District Fitting Departments and Lamp Repairers	 714 who have been adversely affected in the matter of their earnings on account of closing down of the overtime and Sunday Work	 should be compensated for the loss suffered by them; compensation being the amount lost by them since the scheme was introduced. " The Tribunal which dealt with this demand observed that demand No. 11 (a) had been badly worded. There was	 however	 no doubt that what the employees claimed against the appellant was	 in substance	 a demand for paid weekly off only for those workers who were actually getting a weekly off	 though without pay. In dealing with this demand	 the Tribunal noticed the fact that all the monthly paid staff employed by by the appellant got a paid weekly off	and so	it thought that there was no reason to dicriminate between the said staff and the daily rated workers. In regard to the daily rated workers usually	 their mothly income would be determined on the basis of a month consisting of 26 working days. From the Statement of claim 'filed by the Union before the Tribunal	 it appeared that prior to 1946	 most of the workers used to work for all the seven days of the week. By about August	 1946	 however	 weekly offs were enforced upon the major section of the workmen. In June 1946	 the appellant and the Union had entered into an agreement as regards wage scales of various categories of workers	 and the Tribunal assumed that in respect of most of the daily rated workers	 the wages must have been fixed on the basis of what their monthly income would be for 26 working days. It is in the light of this. background that the Tribunal proceeded to examine demand No. 11 (a). The Tribunal noticed that in the case of the four categories of workers specified in demand No. 11 (b)	 difference had to be made because it could not be said in their case that their daily rates of 715 wages were fixed with reference to a month of 26 working days. The result was that with the introduction of the weekly off	 the wages of those workers were reduced. Naturally	 the Tribunal observed that in such a case	 the concession of a weekly off would be a very doubtful benefit if as a result	 the monthly income of the workers was to go down. That is why the Tribunal gave the direction on which the respondents ' present claim is based. This direction we have already quoted at the beginning of the judgment. Having thus dealt with demand No. 11 (a)	 the Tribunal proceeded to examine	 demand No	 11 (b)	 and it ordered that the workers of Mains	 Services and District Fittings Departments and Lamp Repairers who had been adversely affected in the matter of their earnings on account of closing down of Sunday work	 should be compensated for the loss suffered by them	 by payment of their wages and dearness allowance for the weekly off given to them from June 1	 1949 onwards till the date of the publication of the award. The question about the scope and effect of the provisions of section 33C (2) of the Act and the extent of the jurisdiction conferred on the Labour Court by it have been recently considered by us in the case of The Central Bank of India Ltd. vs P. section RajagopaIan (1). That decision shows that the applications made by ' the respondents were competent and the Labour Court had jurisdiction to deal with the question as to the computation of the benefit conferred on the respondents in terms of money. Mr. Kolah for the appellant contends that though the applications made by the respondents may be competent and the claim made by them may be examined under section 33C (2)	 it would	 nevertheless	 be open to the appellant to contend that the award on which the said claim is based is without jurisdiction and if he succeeds in (1) 	 716 establishing his plea	 the Labour Court would be justified in refusing to give effect to the said Award. In our opinion	 this contention is well founded. The proceedings contemplated by section 330 (2) are	 in many cases	 analogous to execution proceedings	 and the labour Court which is called upon to compute in terms of money the benefit claimed by an industrial employee is	 in such cases	 in the position of an executing court; like the executing court in execution proceedings governed by the Code of Civil Procedure the Labour Court under section 33C (2) would be competent to interpret the award on which the claim is based	 and it would also be open to it to consider the plea that the award sought to be enforced is a nullity. There is no doubt that if a decree put in execution is shown to be a nullity the executing court can refuse to execute it. The same principle would apply to proceedings taken under s 33C (2) and the jurisdiction of the labour court before which the said proceedings are commenced. Industrial Tribunals which deal with industrial disputes referred to them under section 10 (1) (d) of the Act are	 in a sense	 Tribunals with limited jurisdiction. They are entitled to deal the disputes referred to them	 but they cannot I outside the terms of reference and deal with matters not included in the reference	 subject	 of course	 to incidental matters which fall within their jurisdiction. Therefore	 on principle	 Mr. Kolah is right when he contends that the Labour Court would have been justified in refusing to implement the award	 if it was satisfied that the direction in the award on which the respondents ' claim is based is without jurisdiction. That takes us to the question about the merits of the plea raised. by Mr. Kolah. Mr. Kolah contends that the direction in question on which the respondent 's claim is based	 is invalid for the reason that the Tribunal travelled outside the terms of reference when it added the words " 'and others" in the 717 said direction. His argument is that the said direction has really been issued under demand No. 11 (b) and since the said demand was confined to the four categories of workmen specified in it	 the Tribunal had no jurisdiction to extend the relief to any workers outside the said four categories by adding the words " and others". Thus presented	 the argument is no doubt attractive	 but on a careful examination of the scheme of the award in so far as it relates to demand No. 11	 it would be clear that the impugned direction has relation not to demand No. 11 (6)	 but to demand No. 11(a)	 and it is obvious that demand referred to all workers and was not confine to any specified categories of workers. It is true that in dealing with the said demand	 the Tribunal prominently referred to the four categories of employees specified in demand No. 11 (b)	 but that is not to say that it was confining the said demand to the said four categories. The said four categories were mentioned specifically because they clearly brought out the cases of workmen to whom relief was due under demand No. 11 (a). Having thus dealt with the said four categories by name	 the Tribunal thought it necessary	 and we think	 rightly	 to add the words "and others"	 because if there were other workmen who were till 1948 required to work on Sundays and in respect of whom a weekly day off was introduced thereafter without any corresponding increase in their wages	 there was no reason why they should not have been given the benefit which was given to the workmen of the four categories specifically discussed. it is significant that having thus comprehensively described the workmen who were entitled to the said benefit	 the Tribunal has added that in respect of the remaining workmen	 demand No. 11 (a) was rejected. Therefore	 we are satisfied that the relief granted by the Tribunal in paragraph 115 of its award has reference. to demand No. 11 (a) and the use of the words "and others" is not only not outside the terms of reference	 but is quite appropriate and justified. 718 That being so	 it is difficult to sustain the plea that the impugned direction was without jurisdiction. Mr. Kolah no doubt relied on the fact that the present respondents never thought that they were entiteld to the benefit conferred by the impugned direction and in support of this plea	 he referred us to the fact that in ' 1952	 a demand was made on their behalf for a similar benefit. If the respondents had felt that the benefit conferred by the impugned direction was available to them	 it is very unlikely says Mr. Kolah	 that they would have made the same demand in 1952 on the basis that it had not been granted to them by the earlier award. It does appear that this demand was made on behalf of the respondents and the Government of Bombay took the view that the said demand had already been considered by the Tribunal and that it was too late to reopen it in regard to other categories of employees; that is why the Government refused to make a reference. In our opinion	 this fact cannot materially assist Mr. Kolah	 because on a fair and reasonable construction of the material direction in the award	 we are satisfied that the said clause applies to all workers of the appellant who satisfy the test prescribed by it. If the respondents did not understand the true scope and effect of the said clause	 that cannot affect the construction of the clause. Therefore	 we do not think that the failure of the respondents to take advantage of the said clause soon after the earlier award was pronounced can have any bearing on the construction of the clause. Then	 Mr. Kolah has suggested that on the merits the respondents are not entitled to make the claim	 because	 it is not shown by them that they were required to work on all Sundays in the relevant years. He argues that the test prescribed by the direction is that the benefit should be available to 719 workmen who were	 till 1948	 required to work on Sundays and that	 it is suggested	 must mean "who were required to work on all Sundays in the year". This argument has been examined by the Labour Court and it has found that the respondents were required to work on Sundays before 1948	 though they might not have attended on all Sundays. In support of this finding	 the Labour Court has referred to Ext. 32 and has drawn the inference from the said document that the workers in the Syphon Department were required to work on all Sundays before September	 1948	 and it has added that the fact that they did not work on some Sundays may be attributed to some casual circumstances	 such as the workers having voluntarily remained absent	 or there not being sufficient work for all	 some might have been sent home. Mr. Kolah has invited our attention to the chart (Ext. 32) and has shown that in some cases	 the employees were not required to work even half the number of Sundays during that year. In our opinion	 this argument proceeds on a misconstruction of the relevant clause in the award. The said clause does not provide that before getting the benefit in question	 the workers must show that they actually worked on all Sundays in the year. The test which has to be satisfied by the workers is that they could have been required to work on Sundays in that year. In other words	 what the Tribunal decided was that if there were workers employed by the appellant whom the appellant could require to work on Sundays during the relevant year	 they would be entitled to the benefit. In other words	 the test is : did the terms and conditions of service impose an obligation on the workers to attend duties on Sundays if called upon to do so? That is very different from saying that the benefit would be available only if the workers in question worked on all Sundays. Therefore	 we do not think there is any substance in the argument that since the respondents had not been actually required to work on all Sundays in the 720 relevant year	 they were not entitled to the benefit of the relevant clause in the award. That leaves one more question to be considered. Mr. Kolah has strenuously argued that the Labour Court should not have allowed the claim of the respondents for such a long period when they made the present applications nearly 8 years after the award was pronounced. It is true that the earlier award was pronounced on May 11	 1950 and the present applications were made in 1958. In support of his argument that the delay made by the respondents should be taken into account	 Mr. Kolah has referred to the fact that under the Payment of Wages Act (No. 4 of 1936) a claim for wages has to be made within six months from the date on which the cause of action accrues to the employees. In the State of Maharashtra	 by local modification	 this period is prescribed as one year. The argument is that the present claim made by the respondents under section 33 C(2) is a claim for wages within the meaning of the Payment of Wages Act. If the respondents had made such a claim before the authority under the said Act	 they could not have got relief for more than a year. It would be anomalous	 says Mr. Kolah. that by merely changing the forum	 the respondents should be permitted to make a claim for as many as 8. years under section 33C (2). In this connection	 Mr. Kolah also contends that by virtue of section 22 of the Payment of wages Act	 a claim for wages cannot be made by an industrial employee in a civil court after a lapse of one year	 because though the period for such a.	 suit may be 3 years under article 102	 a civil suit is barred by section 22. The jurisdiction conferred on the payment authority is exclusive and so far as the said Act goes	 all claims must be made within one year. Prima facie	 there is some force in this argument. It does appear to be somewhat anomalous that a claim which would be rejected as barred by 721 time if made under the Payment of Wages Act.	 should be entertained under section 33C (2) of the Act; but does this apparent anomaly justify the introduction of considerations of limitation in proceedings under section 33C (2)? Mr. Kolah suggests that it would be open to this Court to treat leaches on the part of the employees as a relevant factor even in dealing with case under section 33C (2) and he has relied one fact that this Court has on several occasions discouraged belated claims in the matter of bonus. in appreciating the validity of this I argument	 we do not propose to consider whether the jurisdiction conferred on the authority under the Payment of Wages Act is exclusive in the sense that a claim for wages cannot be made by an industrial employee in a civil court within 3 years as permitted by article 102; that is a question which may have to be decided on the merits when it directly arises. For the purpose of the present appeal	 the only point which we have to consider is : does the fact that for recovery of wages limitation has been prescribed by the payment of Wages Act. Justify the introduction of considerations of limitation in regard to proceedings taken under section 33C (2) of the Act ? In dealing with this question	 it is necessary to bear in mind that though the legislature knew how the problem of recovery of wages had been tackled by the Payment of Wages Act and how limitation had been prescribed in that behalf	 it has omitted to make any provision for limitation in enacting section 33C (2). The failure of the legislature to make any provision for limitation cannot	 in our opinion	 be deemed to be an accidental omission. In the circumstances	 it would be legitimate to infer that legislature deliberately did not provide for any limitation under section 33C (2). It may have been thought that the employees who are entitled to take the benefit of section 330 (2) may not always be conscious of their rights and it would not be right to put the restriction 722 of limitation in respect of claims which they may have to make under the said provision. Besides	 even if the analogy of execution proceedings is treated as relevant	 it is well known that a decree passed under the Code of Civil Procedure is capable of execution within 12 years	 provided	 of course	 it is kept alive by taking steps in aid of execution from time to time as required by article 182 of the Limitation Act	 so that the test of one year or six months ' limitation prescribed by the Payment of Wages Act cannot be treated as a uniform and universal test in respect of all kinds of execution claims. It seems to us that where the legislature has made no provision for limitation	 it would not be open to the courts to introduce any such limitation on grounds of fairness or justice. The words of section 33C (2) are plain and unambiguous and it would be the duty of the Labour Court to give effect to the said provision without any considerations of limitation. Mr. Kolah no doubt emphasised the fact that such belated claims made on a large scale may cause considerable inconvenience to the employer	 but that is a consideration which the legislature may take into account	 and if the legislature feels thatch play and justice require that some limitations be prescribed	 it 'may proceed to do so. In the absence of any provision	however	 the Labour Court cannot import any such consideration in dealing with the applications made under section 33C (2). Mr. Kolah then attempted to suggest that article 181 in the First Schedule of the Limitation Act may apply to the present applications	 and a period of 3 years ' limitation should	 therefore	 be held to govern them. Article 181 provides 3 years ' limitation for applications for which no period of limitation is provided elsewhere in Schedule 1	 or by section 48 of the Code of Civil Procedure	 and the said period starts when the right to apply accrues. In our opion	 this argument is one of desperation. It is well settled 723 that article 181 applies only to applications which are made under the Code of Civil Procedure	 and so	 its extension to applications made under section 33C (2) of the Act would not be justified. As early as 1880	 the Bombay High Court had held in Rai Manekbai vs Manekji Kavasji (1)	 that article 181 only relates to applications under the Code of Civil Procedure in which case no period of limitation has been prescribed for the application	 and the consensus of judicial opinion on this point had been noticed by the Privy Council in Hansraj Gupta vs Official Liquidator8	 Dehra Dun Mussoorie Electric Tramway Company Ltd. (2) An attempt was no doubt made in the case of Sha Vulchand & Co. Ltd. vs Jawahar Mills Ltd. (3)	 to suggest that the amendment of articles 158 and 178 ipso facto altered the meaning which had been attached to the words in article 181 by judicial decisions	 but this attempt failed	 because this Court held " 'that the long catenate of decisions under article 181 may well be said to have	 as it were	 added the words "under the Code" in the first column of that Article. " Therefore it is not possible to accede to the argument that the limitation prescribed by article 181 can be invoked in dealing with applications under section 33C (2) of the Act. It is true that in dealing with claims like bonus	 industrial adjudication has generally discouraged laches and delay	 but claims like bonus must be distinguished from claims made under section 33C (2). A claim for bonus	 for instance	 is entertained on grounds of social justice and is not based on any statutory provision. In such a case		 it would	 no doubt	 be open to industrial adjudication to have regard to all the relevant considerations before awarding the claim and in doing so	 if it appears that a claim for bonus was made after long lapse of time	 industrial adjudication may refuse to entertain the claim	 or Government nay refuse to make reference in that behalf. But these considerations would (1)[1880] I.L R. (2) [1932] L.R. 60 I.A. 13	 20. (3) ; 	 371 	 724 be irrelevant when claims are made under section 33C (2)	 where these claims are	 as in the present case	 based on an award and are intended 'merely to execute the award. In such a case	 limitation cannot be introduced by industrial adjudication on academic ground of social justice. It can be introduced	 if at all	 by the legislature. Therefore	 we think	 that the Labour Court was right in rejecting the appellant 's contention that since the present claim was belated	 it should not be awarded. In the result	 the appeals fail and are dismissed with costs. Appeals dismissed.

Petitions were filed by sixteen respondents under section 33C(2) of the 	 claiming certain benefits under an award made by an Industrial Tribunal. The prayer was to compute the benefits in terms of money and direct the appellant to pay the same to them. Many objections were raised by the appellant but these were rejected by the Labour Court which accepted the claim of the respondents and directed the appellant to pay to the respondents the respective amounts specified against their names in the award. The appellant came to this Court by special leave. The contentions raised by the appellant before this Court were that the award	 on which the claim was based	 was without jurisdiction and hence the Labour Court should have refused to implement it; that in order to get benefit	 the workers must show that they actually worked on all Sundays in the year before September	 1948; and that as the claims of the respondents were belated	 those should not have been awarded. Held that the Labour Court would have been justified In refusing to implement the award if it was satisfied that the 710 direction in the award on which the respondents ' claim was based	 was without jurisdiction	 but as that was not actually so	 the impugned direction was according to law. The applications made by respondents were competent and the Labour Court had jurisdiction to deal with the question as to the computation of the benefit conferred on the respon dents in terms of money. The proceedings contemplated by section 330 (2) were	 in many cases	 analogous to execution proceed ings and the Labour Court which was called upon to compute in terms of money the benefit claimed by an industrial employee	 was in the position of an executing court and was competent to interpret the award on which the claim was based and also consider the plea that the award	 sought to be enforced	 was a nullity. Held also	 that there was no substance in the argument that since the respondents had not been actually required to work on all Sundays in the relevant year	 they were not entitled to the benefit given in the award. The test which had to be satisfied by the workers was that they could have been required to work on Sundays in that year and not that they actually so worked. Held also	 that the legislature has not made any provision for limitation for applications under section 33C (2) and it was not open to the Courts to introduce any such limitation on grounds of fairness or justice	 The words of section 33 C (2) were plain and unambiguous and it was the duty of the Labour Court to give effect to the said provisions without any considerations of limitation. The employees who are entitled to take the benefit of section 33C (2) may not always be conscious of their right and it would not be right to put the restriction of limitation in respect of claims which they may have to make under the said provision. There was no justification for applying the provisions of the Payment of Wages Act and article 181 of the Limitation Act to the proceeding under section 33C (2). Claims like bonus arc distinguishable from claims made under section 33C (2). A claim for bonus is entertained on grounds of social justice and is not based on any statutory provision and in such a case	 it is open to industrial adjudication to have regard to all the relevant considerations before awarding the claim and in doing so if it appears that a claim for bonus was made after long lapse of time	 industrial adjudication may refuse to entertain the claim or Government may refuse to make the reference in that 	 behalf. 711 However	 those considerations are irrelevant when claims we made under section 330 (2). In such cases limitation cannot be introduced by industrial adjudication on academic grounds of social justice.
