Summarize the following court judgment. Appeal No. 1734 of 1967. Appeal by Special Leave from the Award dated the May 19	 1967 of the Industrial Tribunal (1) at Allahabad in Adjudication Case No. 15 of 1960. section V. Gupte	 D. N. Mukherjee and Gautam Banerjee	 for the appellant. G. C. Bhattacharyaand M. V. Goswami	 for respondents Nos. 1 and 3 to 8. O. P. Rana	 for respondent No. 9. The Judgment of the Court was delivered by Grover	 J. This is an appeal by special leave from an award of the Industrial Tribunal	 Allahabad	 dated May 19	 1967. 757 The material facts May be stated	 The appellant	 which is a limited liability company and which later on went into voluntary liquidation	 was carrying on the business or undertaking of generation	 distribution and supply of electricity. One of such undertakings was the Electric Supply Undertaking at Allahabad in the State of Uttar Pradesh. Its affairs and business were being% looked after and managed by Martin Bum & Co. I Ad.	 Calcutta. Some of the appellant 's workmen in Allahabad and its surrounding area were members of Bijli Mazdoor Sangh a trade union registered under the Indian Trade Union Act	 1926. The U.P. State Electricity Board compulsorily acquired and took over the assets of the appellant 's aforesaid undertaking or business with effect from 16/17th September 1964. In accordance with the provisions of the 	 hereinafter called the 'Act and the U.P. Industrial Employment (Standing Orders) Rules 1946 the appellant submitted draft Standing Orders defining the conditions of employment of its employees. On July 14	 1951 these Orders 'were certified by the Certifying Officer. Clause 32 of the Standing Orders was in the following terms : "32. RETIREMENT An employee who has served 30 years or who has reached the age of 55 will be retired	 but exemption to this may be granted by the Company in special cases". The workmen through the Bijli Mazdoor Sangh preferred an appeal under section 6 of the Act from the order of (the Certifying Officer to the State Industrial Tribunal which was the. appellate authority under the Act. That appeal	 however		 was dismissed. The Agra Electric Supply Co. Ltd.	 Agra and Benaras Electric Light & Power Co. Ltd.	 Varanasi	 which is the appellant in the connected appeal (C.A. 164/68) also got certified Standing Orders in similar terms. These electric undertakings	 were also under the management of Martin Burn & Co. Ltd. On July 16	 1959 notices were served on seven worlen with effect from September 1	 1959 on the ground that they had attained the age of superannuation or completed 30 years of service and they were retired by reason of their having attained the age of superannuation. Out of these workmen one of them Haider Ali died during the pendency of proceedings. The other six employees have been impleaded as respondents Nos. 1 to 6 in the present appeal. According to the appellant these	 respondents accepted all the accumulations due to them in respect of Provident Fund contributions made by the appellant in respect of them and by themselves and were also paid gratuities credited to them in their res 758 pective Provident Fund accounts for their services prior to their becoming members of the Provident Fund. By an order dated February 22	 1960 made under section 4 K of the U.P. Industrial Disputes Act 1946 the Government of U.P. referred to the Industrial Tribunal (1) at Allahabad for adjudication an industrial dispute alleged to exist between the appellant and its workmen on the following issues : "Whether the employers have wrongfully arid/or unjustifiably retired their workmen	 mentioned in the Annexure	 with effect from 1st August	 1959 ? If so	 to what relief are the workmen entitled ?" Respondents 1 to 6 and Haidcr Ali (since deceased) were the workmen mentioned in the Annexute. The case of the workmen before the Industrial Tribunal was that they had entered service of the appellant prior to the certification of the Standing Orders. At the time of their appointment there was no condition that they would be liable to retirement after attaining any prescribed age or after putting in any fixed period of service. A practice was in vogue that the workmen would continue in service till he was physically fit. Accordingly clause 32 of the certified Standing Orders was neither binding nor enforceable. The Industrial Tribunal made an award on May 2	 1960 finding	 interalia	 (a) the employers were within their rights in retiring	 the workmen concerned. (b) The act of the employers in compulsorily retiring the concerned workmen	 from service could not be characterised as wrongful	 illegal or unjustified and (c) the workmen were entitled to no relief. On June 14	 1960 the Bijli Mazdoor Sangh moved an appli cation under section 10(2) of the Act for amendment and modifica tion of clause 32 claiming fixation of retirement age at 60 years. On September 20	 1960 the Union also filed a writ petition in the Allahabad High Court for quashing the award. On April 22	 1961 the Certifying Officer modified clause 32 and fixed the ago	 of retirement at 58 years. On September 10	 1961 the appellate authority refixed the age of retirement at 55 years. Similarly appeals were filed by the Agra Electric Co. and the Banaras Electric Light and Power Co. Ltd. in which similar orders were made. On July 12	 1966 the	 High Court recorded an order quashing the award. It was held that Standing Order 32 was not applicable to the employees Who had entered service before the certification of the Standing Orders. The Industrial Tribunal was directed to reheat the case and after giving an opportunity to the parties of being heard give an award in accordance with law. Finally the award against which the appeal has been brought 759 was given on May 19	 1967. It was held in the award that all the seven workmen had been wrongfully and unjustifiably retired and that they should be deemed to have continued in service till September 16	 1964 from which date they would be taken to Wave been retrenched. The appellant having been taken over by the U.P. State Electricity Board	 it was directed that the employers should pay full wages from the period August 1	 1959 to September 16	 1964 and retrenchment compensation within section 25 F read with section 25 FF and section 25 J of the . While deciding the writ petition the High Court relied on three decisions of this Court for holding that where there is no age of superannuation prescribed for the employees of a concern a provision in the Standing Orders certified subsequent to the date of employment regarding compulsory retirement will not be applicable to them. The first decision is in Guest Keen	 Williams Private Ltd. vs P. J. Sterling & Others(1). In that case after the enforcement of the Act the industrial concern submitted its draft Standing Orders for certification to the Certifying Officer. That Officer certified the Standing Orders after giving the trade union of workmen an opportunity to be heard and after considering their objections. The Standing Orders relating to retirement provided that the workmen shall retire from the service of the company on reaching the age of 55 years. The company gave notice to forty seven of its workmen who were over the age of 55 years retiring them and a dispute was raised about their retirement which was referred to the Tribunal for adjudication It was ultimately held	 by the Labour Appellate Tribunal that those workmen who were in employment prior to the date of certification of the Standing Orders would not be governed by it and their retirement was illegal. This Court examined the scheme of the Act including the relevant provisions. Notice wag taken	 in particular	 of the fact that when the standing Orders were submitted to the Certifving Officer all that he could do was to satisfy himself that they made provision for other matters set out in the schedule to the Act and that they were otherwise in conformity With its provisions. Under section 4	 as it was orignally enacted the Certifying Officer could not adjudicate upon the fairness or reasonableness of the provisions of the Standing Orders. This section was subsequently amended in 1956 and the effect of the amendment was that the Certifying Officer was enabled to adjudicate upon the fairness or reasonableness of the provisions of the Standing Orders. It was pointed out by the court that the scope for enquiry before the Certifying Officer prior to the amendment of section 4 was extremely limited. The only way in which the employees could claim modification of the standing Orders prior to the amendment of section 4 was by raising an industrial dispute in that (1) ; 760 behalf. Subsequent to the amendment the employees could raise the same dispute before the Certifying Officer and in a proper case they could apply for its modification under section 10(2) of the Act. It was observed that the Standing Orders certified under the Act became part of the terms of the employment by operation of section 7 but if an industrial dispute arose in respect of such Orders and it was referred to the Tribunal by the appropriate Government the Tribunal had the jurisdiction to deal with it on the merits. It was	 therefore	 held that the Tribunal had to consider not only the propriety	 reasonableness and fairness of the rule but it had also to deal with the question as to whether the said rule could and should be made applicable to employees who had already been employed without any limit as to age of retirement. The decision in this case was followed in Workmen of Kettlewell Bullen & Co. Ltd. vs Kettlewell Bullen & Co. Ltd.(1). The next case in which a similar question arose in Salem Erode Electricity Distribution Co. Ltd. vs Salem Erode Electricity Distribution Co. Ltd. Employees Union(2). It was claimed by the company which was the employer there that the urgent need for increased production and supply of electrical energy could be met if the existing rules embodied in two of its certified Standing Orders relating to holidays and leave were suitably amended. The amendments proposed sought to introduce different rules relating to holidays and leave for employees who were appointed before a specified date and those who joined service after that date. Both the Certifying Officer and the appellate authority disallowed the amendments. The company appealed	 to this Court and the scheme of the Act was examined once again. It was emphasised that after the amendment of section 4 of the Act made in 1956 jurisdiction had been conferred on the Certifying Officer as well as the appellate authority to adjudicate upon the fairness or easonableness of the provisions of the Standing Orders. Thus the jurisdiction had been widened. Moreover under section 10(2) as originally enacted it was only the employer who could make an application to the Certifying Officer to I have the Standing Orders modified. By the amendment made in 1956 even workmen were enabled to exercise that right. Addressing itself to the question whether it was permissible for an industrial establishment to have two sets of Standing Orders to govern the relevant terms and conditions of its employees it was laid down after an examination of the scheme of the relevant provisions of the Act in the light of the matters specified in the Schedule that there was no scope for having separate Standing Orders in respect of any one of them	 It was said ". . the conclusion appears to be irresistible that the object of the Act is to certify Standing Orders in (1) (2) ; 761 respect of all the matters covered by the schedule and having regard to these matters Standing Orders so certified would be uniform and would apply to all Workmen alike who are employed in any industrial establishment". It was considered that Guest Keen Williams Pvt. Ltd.(1) could afford no asistance because that matter came to this Court from an industrial dispute which was the subject matter of industrial adjudication and all that this Court did was to fixed the age of superannuation for workmen who had been employed prior to the date of the certification of the relevant Standing Orders. That course was adopted in the special and unusual circumstances of that case. In the next decision Agra Electric Supply Co. Ltd. vs Sri Alladin & Ors.(2) one of the main questions was whether three workmen who had been employed long before 1951 when the cornpany 's Standing Orders were certified could be retired under Standing Orderwhich prescribed the age of superannuation as 55 years. ThisCourt took a view which seemingly runs counter to Guest KeenWilliams Pvt. Ltd.(1). It was held that the Standing Orders when certified would be binding on the employers as well as all the workmen who were in employment at the time the Standing Orders came into force and those employed thereafter as uniform conditions of service. The process of reasoning which prevailed was (1) the Act is a beneficient piece of legislation	 its object being to require employers in industrial establishments to define with sufficient precision the condtions of employment of workmen employed therein and to make them known to such workman. (2) Before the passing	 of the Act there was nothing in law to prevent an employer having different con tracts of employment with workmen which led to confusion and made possible discriminatory treatment. This was also clearly incompatible with the principles of collective bargaining. (3) Section 3 of the Act was enacted to do away with such diversity and bargaining with each individual workman. (4) Section 4 indicates that particulars of workmen in the employment on the date of the submission of the draft Standing Orders or certification and not of those only who could be employed in future after certification were to be given. (5) Sections 4 and 5 show that draft orders are certifiable if they provide for all matters set out in the schedule and are otherwise in conformity with the Act and if they are adjudicated as fair and reasonable by the Certifying Officer or the appellate authority. The Certifying Officer has also to forward a copy of the draft Standing Orders to the Union (1) ; (2) ; 762 or to the workmen in the prescribed manner and has to decide whether or not any modification or addition should be made after hearing the	 Union or the	 workmen concerned. Sections 6	 7	 9 and 10 contain provisions for appeal by aggrieved persons as also for sending of authenticated copies by the Certifying Officer to the parties where no appeal is filed and further the employer has to post the Standing Orders as finally certified in the manner prescribed. The employer or the workmen can even apply for modification after expiry of six months from the date on which the Standing Orders or the last modification thereof comes into operation. (7) The schedule	 sets out the matters which the Standing Orders must provide for. For the reasons given above this Court held that the Act was meant to enable Standing Orders to be made to bind not only those who were employed subsequent to their certification but also those who were already in employment. If any other result were to follow there would be different conditions of employment for different classes of workmen which would render the conditions of their service as indefinite and diversified as befoe the 	enactment of the Act. Support was derived from the decision in Salem Erode Electricity Distribution case(1) in which departure was made from the view previously taken in the case of Guest Keen William	s Pvt. Ltd.(2) It has been urged before us on behalf of the respondents that the decision in Guest Keen Williams Pvt. Ltd. (2) still holds the field and the point which was decided there and which arises in the present case did not come up for consideration in Salem Erode Electricity Distribution Co. Ltd.(1). In our opinion the principle applied in the latter case is fully supported by the scheme of the Act and was rightly extended and applied 'in Agra Electric Supply Co. Ltd. (3). We concur with the view expressed therein that it was not intended by the legislature that different sets of conditions should apply to employees depending on whether a workman was employed before the Standing Orders were certified or after	 which would defeat the very object of the legislation. In the preamble it is stated in categorical terms "whereas it is expedient to require employers in industrial establishments to define with sufficient precision the conditions of employment under them and to make the said conditions known to workmen employed by them". Not only the object but the scheme of the Act is such that the employers must define precisely the ponditions of employment of all the employees and have the same certified by the Certifying Officer against whose orders an appeal lies to the appellate authority. The	 right given to workmen to express their (1) ; (3) ; (2) ; 763 view and to raise objections is of great significance. They can even ask for modification of the Standing Orders in accordance with section 10 of the Act. Every possible safeguard has been provided for keeping the workmen informed about their conditions of service so that they can take whatever steps they desire or are advised to take in their interest before the Certifying Officer or the appellate authority. It is also very difficult to conceive	 taking each individual item in the schedule how there can be different conditions for different employees depending upon the point of time when they came to be employed; for instance item 3 relates to shift working. It is possible to suggest that for the same kind of work employees who were in employment before the Standing Orders were certified would have different hours of shift from the other employees who were employed subsequently. In the very nature of things a great deal of irritation and annoyance between employees inter se would result if any such discrimination is made in any of the items in the schedule. It has been rightly pointed out in Agra Electric Supply Co. Ltd. that this would only lead to industrial unrest and not industrial peace	 the latter being the principal object of legislation. It must be remembered that in Guest Keen Williams Pvt. Ltd. the Certifying Officer could not go into the reasonableness or fairness of the Standing Orders according to section 4 of the Act as it stood at the material time. The law was changed only in 1956. Perhaps that was one of the main reasons which prompted the court in taking the view it did. But after the amendment of the law in 1956 the Certifying Officer and the appellate authority are duty bound to examine the question of fairness of the Standing Orders and there can be no justification now not to give	 effect to the principle of uniformity of conditions of service which is clearly conte mplated by the provisions of the	 Act. The next question for determination is whether clause 32 of the Standing Orders relating to age of retirement could be certifled in July 1951. On behalf of the respondents it has been pointed out that there is no item in the schedule which covers the case of retirement or superannuation. Items 8 and 9 are in these terms "8. Termination of employment and the notice thereof to be given by employer and workmen	 9. Suspension or dismissal for misconduct	 and acts or omissions which constitute misconduct. " The model Standing Orders framed by the Central Government and by the Government of the State of Uttar Pradesh did not contain any clause relating to retirement or superannuation. It was for the first time that on November 17	1959 item 11 C 764 relating to superannuation and retirement was introduced by the State of U.P. in exercise of the rule making powers conferred by section 15 of the Act. In other States the item relating to age of retirement or superannuation was introduced either by legislation or by the exercise of rule making power. In the State of Bombay section 19 of the Industrial Employment (Standing Orders) (Bombay Amendment) Act 1957 provided for insertion of item 10 A in the Schdule which was "age for retirement or superannuation". According to counsel for the respondents there was no item until the introduction of item 11 C in November 1959 in the schedule under which any Standing Orders could be framed and got certified relating to the age of retirement and superannuation. It has been maintained that items 8 and 9 cannot possibly include retirement and superannuation and therefore till item 11 C was added in the schedule so far as the State of U.P. was concerned in November 1959 no Standing Orders could be legally or validly framed and certified providing for age of retirement and superannuation. In Saroj Kumar Ghosh vs Orissa State Electricity Board(1) the Orissa High Court considered this question a some length and expressed the view that where a Standing Order has been certified by the Certifying Officer containing a clause relating to superannuation not covered by the schedule of the Act norr by the model Standing Orders such certification cannot be valid under section 4 of the Act. The clause 'termination of employment ' in item 8 of the schedule cannot be equated with the word "superannuation". According to the Orissa High Court	 superannuation is an event which comes more or less in an automatic process. An age is fixed on the reaching of which the holder of office has no option but to go out of office. There is no volition involved in that act. The employer and the employee have notice of the matter long before the event is to occur and the event is such that it cannot be arrested by either one of them if the rule is to be followed. On the other hand termination is a positive act by which one party even against the desire of the other can bring about the end of employment. The judgment of the learned single. judge in Management of the "HINDU"	 Madras vs Secretary Hindu Office & National Press Employees Union and another(2) was dissented from. In that case the expression "termination of employment" in item 8 was considered to be wide enough to include retirement of an employee at the age of superannuation. The learned Madras Judge sought support from para 16 of the model Standing Orders which is as follows "Every permanent workman shall be entitled to a service certificate at the time of his dismissal discharge ' or retirement from service". 	 (1) A.I.R. 1970 Orissa 126. (2) 765 In the model Standing Orders there was no clause providing for superannuation or retirement on attaining a certain age. In our judgment much assistance or help cannot be derived from para 16 of the model Standing Orders as contained in schedule 1 to the Industrial Employment (Standing Orders) Central Rules 1946. Retirement which is mentioned there may be under the terms of contract of employment entered into between the employer and the employees. Section 2(oo) of (the throws a certain amount of light on the matter. It is reproduced below :	 "Retrenchment" means the termination by the employer of the service of a workman for any reason whatsoever	 otherwise than as a punishment inflicted by way of disciplinary action	 but does not include (a) voluntary retirement of the workman; or (b) retirement of the workman on reaching the age of	 superannuation if the contract of employment between the employer and the workman concerned contains a stipulation in that behalf;" It shows	 firstly	 that termination 'of service of a workman is distinct from retirement on reaching the age of superannuation; secondly	 retirement can take place on resch & the age of superannuation under the terms of the contract of employment entered into between the employer and the workman. Therefore	 the word "retirement" in para 16 cannot be regarded as conclusive of the question whether termination of: employment includes retirement and superannuation. In the schedule to the Act item 8 covers termination of employment and the notice to be given either by the employer or the workman and item 9 relates to sus pension or dismissal for misconduct etc. Item 8 by virtue of the language employed does not appear to cover the case of superannution which does not depend on any notice and which covers an event which is automatic and which must be given effect to without any volition on the part of the employer or the workmen as pointed out in the Orissa judgment. If termination is to be read in a wide sense as meaning employment coming to an end there was a necessity to have item 9 because dismissal would then be covered by termination. In the context in which the word "	termination" is used in item 8 it cannot mean each and every form of termination or cessation of employment. From para 13 of the Model Slanding Orders contained in schedule 1 to the Industrial Emtployment (Standing Orders) Central Rules 1946	 it is apparent that item 8 is confined to termination of employment by notice in writing and does not contain any mention L1061 Sup. CI/72 766 of superannuation or retirement. It was perhaps this difficulty which prompted the state or U.P. to introduce item 11 C in exercise of the rule making powers conferred by section 15 of the Act and the bombay legislature to make similar amendment by legislation. it would follow that unless an employer can include a clause relating to the age of retirement and superannuation and the Certifying Officer can certify it even though no such item appears in the schedule to 	the Act clause 32 as certified in 1951	 in the present case	 could not be regarded to be valid. The Madras High Court in the case of Management of the 'Hindu '	 Madras(1) made some observations to the effect that there was no bar to the Standing Orders making a provision for matters other than those specifically mentioned in the schedule so long as 	the Certifying Officer certifies them on he ground that they are fair and reasonable. The Orissa High Court	 however	 in Sarojkumar Ghosh 's(2) case did not subscribe to this view. Learned counsel for the appellant	 apart from relying on the Madras decision	 has not addressed any arguments on the larger and wider question as to whether even in the absence of any item in the schedule Standing Orders can be framed on certain matters which may be regarded as fair and reasonable and which may be so certified by the Certifying Officer. it is	 however	 unnecessary to decide this point in the present case because clause 32 of the Standing Orders on which the appellant has relied was certified in July 1951 when according to the express language of section 4 of the Act the Certifying Officer or the appellate authority was debareed from adjudicating upon the fairness or	 reasonableness of the provisions of any Standing Orders. It is difficult to understand how the Certifying Officer at that point of time and before the amendment of section 4 in 1956 could have possibly certified ;my Standing Order which did not relate to any item in the schedule on the ground that it was fair or reasonable Indeed the function of the Certifying Officer	 before the amendment of 1956	 was very limited as is clear from section 3 (2) of the Act which says : "Provision shall be made in such draft for every matter set out in this schedule which may be applicable to the industrial establishment and were model Standing Orders have been prescribed	 shall be	 so far is practicable	 in conformity with such model". We must	 therefore	 hold that	 clause 32 of the Standing Orders as certified in July 1951 was not valid and cannot be binding on the respondents. However	 after item 11 C was introduced in the schedule so far as the State of U.P. was concerned an item was added providing for the age of retirement and superannuation. The Certifying Officer	 when lie modified clause 32 and (1) (2) AIR 1970 Orrissa 126. 767 fixed the	:retiring age at 58 on April 22	 1961 could have validly certified such clause as modified by him. The necessary consequence will be that the respondents could not have been relied 'on the ground of superannuation in July 1959 and they could be validly retired only on or after April 22	 1961 in accordance 	with clause 32 as modified by the Certifying Officer. In other words	 those out of the present respondent who had attained the age of 58 years on April 22	 1961	 could be regarded as having been validly retired having reached the age of superannuation on that date under that clause. In view of the previous decisions of this Court and in particulaw that of Guest Keen Williams Pvt. Ltd.(1) it has not been disputed that in the industrial dispute which was referred it was open ' 'to the Industrial Tribunal or the Labour Court to determine the age of retirement or superannuation notwithstanding that clause 32 of the Standing Orders as certified in 1961 had been legally 	And validly certified indeed in Guest keen Williams Pvt. Ltd.(1) It was not disputed that even this. Court could give an appropriate direction which might 'be considered reasonable with regard to 'the age of superannuartion as stated before according to clause 32 of 'the Standing Orders	 as certified in April 1961	 the age of superannuation was fixed at 58. The appellant 'filed an appears that in the cage of Agra Electric Supply Co.(2) also a appears that in the case of Agra Electric supply Co.(4) also a similar Standing order had been certified and on appeal the age of retirement was reduced from 58 to 55 years by the appellate 'authority. This Court in that case held the Standing Order fixing the age at 55 years applicable not only to those employees who were employed subsequently but also to all workmen who were in employment at the time when the 'Standing Orders became legally applicable. It does not appear in that case that any such argument was raised that the matter should be remitted either to the Industrial Tribunal or the Labour Court to fix the age of superannuation or that this Court itself might do so as was the course followed in the case of Guest keen Williams Pvt. Ltd.(1) in which the age was fixed at 60 years with regard to those employees who had raised the dispute on the ground that the Sanding Orders could not govern them as they had been employed before the Standing Orders became applicable. After considering the entire material and keeping in mind the fact that according to the appellate authority even the age of retirement at 55 was fair and reasonable we are of the view that the age of superannuation of the respondents	 in the present case	 should be 58 years. In other words. it will be the same as was fixed by the Certifying Officer by modifying clause 32 on April 22	 1961. (1) ; (2) ; 768 Lastly we must deal with the contention raised on behalf of the respondents that the order of the Allahabad High Court made on July 12	 1966 quashing the award after following the decision of this Court in Guest Keen Williams Pvt. Ltd.(1) should be deemed to be final and should debar any fresh consideration or decision of that point by virtue of the rule or principle of res judicata. It is noteworthy that the order of the Allahabad High Court was not final against which the matter could have	 been taken in appeal either to a division bench of the High Court or to this Court. Reliance has been placed on a decision of this Court in Management of Northern Railway Cooperative Society Ltd. vs Industrial Tribunal Rajasthan	 Jaipur and Another(2)	 where reference had been made by the State Government to the Industrial Tribunal on the Railway Workers ' Union having raised an industrial dispute against the Management of the Northern Railway Cooperative Society Ltd. The society filed a writ petition on the ground that the dispute having been raised by the Railway Workers ' Union and not by the Society 's own employees the reference to the Tribunal was not competent. The High Court dismissed the petition. thereafter the Tribunal heard the matter and gave its deci sion in favour of the workman concerned. The society appealed to this Court by special leave. It was held that the order of the High Court was not interlocutory but was a final order in regard to the proceedings under article 226. The appropriate remedy for the appellant in that case was to appeal against the High Court 's order and that not having been done the appellant 's plea relating to the competency of the reference was barred by res judicata as the same had been raised before the High Court and had been rejected. The present case is clearly distinguishable inasmuch as the order made by the High Court was not final and a remand had been directed presumably under article 227 of the Constitution. That order in fact did not finally terminate any proceedings at all. The proceedings were terminated only by the award against which the present appeal has been brought by special leave. We are unable to see how the decision in the aforesaid case can afford any assistance to the respondents before us. Indeed the case which is more apposite in Satyadhyan Ghosal & Ors. vs Smt. Deorajin Debi & Another ( 3 ) . There an order of remand had been made by the High Court while exercising powers under section 115 of the Code of Civil Procedure. It was observed	 after referring to the various decisions of the Privy Council	 that the order of remand was interlocutory and did not pumort to dispose of the case. A party is not bound to appeal against every interlocutory order which is a step in the procedure that leads up to a final decision or award. (1) ; (3) ; (2) ; 769 The following observations from this case may be reproduced with advantage "Interlocutory judgments which have the force of a decree must be distinguished from other interlocutory judgments which are a step towards the decision of the dispute between parties by way of a decree or a final order". We are unable	 therefore	 to accede to the contention that the rule of res judicata could be invoked by the	 respondent in the present case. In the result the appeal is allowed and the order of the Industrial Tribunal is hereby set aside. According to our decision the workmen concerned could not have been retired on the ground of superannuation in accordance with clause 32 of the Standing Orders till it was certified after necessary modification on April 22	 1961. Even otherwise it has been held by us that the proper age of retirement in 	he case of those employees who joined service prior to April 22	 1961 should be 58 years. The award	 therefore	 will be that the concerned workmen should be deemed to have continued in service of the appellant till they had at attained the age of 58 years. It is declared that they shall be entitled to be paid full wages and all other dues to which they are entitled under 	the terms of their employment till they attained the age of 58 years. As regards any payments received by the workmen pursuant to the award or after the notice of termination those shall also be adjusted accordingly and the appellant undertakes not to claim_refund of any amounts which have already between received by them in excess of the amounts due. No order as to costs. V.P.S. Appeal allowed.

In accordance with the provisions of the 	 and the U.P. Industrial Employment (Standing Orders) Rules	 1946	 the appellant substituted draft standing defining the conditions of employment of its employees and they were certified bythe Certifying Officer in 1951. Clause 32 of the Standing Orders provided that an employee who has served 30 years or who has reached the age of 55 years will be retired	 but	 exemption from this may be granted by the company in special case. In 1959	 notices were served on the respondent workmen that they were retired by reason of their having attained the age of superannuation as per cl. 32. The workmen contended that the clause was not binding or enforceable as far as they were concerned	 because	 they had entered the service of the appellant prior to the certification of the Standing Orders and there was no condition that they would be liable to retirement after attaining any prescribed age or any fixed period of service	 and that they were entitled to continue in service as long as they were physically. The industrial dispute was referred to the Industrial Tribunal and the Tribunal held in favour of the appellant. The respondents filed a writ petition in the High Court They also applied in 1960	 under s ' 10(2) of the 	 for amendment and motification of cl. 32 claiming fixation of retirement age at 60. The Certifying Officer modified the clause and fixed the age of retirement at 58	 but the appellate authority refixed it at 55. The High Court	 in the writ petition	 on the basis of the decision or this Court in Guest Keen Williams Pvt. Ltd.; 	 her that Cl. 32 was not applicable to the employees and directed the Tribunal to rehear the case. The Tribunal thereafter held that the respondent. workmen were wrongfully and unjustifiably retired. In appeal to this Court	 HELD : (1) It was not intended by the Legislature that different sets of conditions should apply to employees depending on whether workman was employed before the Standing Orders were certified by after	 as that would defeat the object of the legislation. The objection and 755 scheme of the Act is that the employers must define precisely the conditions of employment of all the employees and have them certified by the Certifying Officer. The right given to be workmen to express their views	 to raise objections	 to appeal to the appellate authority and to ask for modification of the Standing Orders under section 10 of the Act	 show that every possible safeguard has provided in the interests of the workmen. Moreover	 the individual items in the Schedule to the Act show that there cannot be different conditions for different employees depending upon the point of time when they came to be employed	 for that would result in a great deal of heart burning between the employees inter se. [762 F H; 763 A D] Salem Erode Electricity Distribution Co. Ltd. vs Its Workers; ; 	 and Agra Electric Supply Co. Ltd.	 vs Sri Alladin & Ors. ; 	 followed. (2) The decision in Guest Keen Williams Pvt. Ltd. that the Industrial Tribunal had to consider not only the propriety	 reasonableness and fairness of a Standing Order but that it had also to deal with the question as to whether a particular Standing Order could be made applicable to employees who had already been employed without any limit as to age of retirement was delivered under the unamended section 4 of the Act	 under which the Certifying Officer or the appellate authority could not go into the reasonableness or fairness of the Standing Orders. But after the amendment of the section in 1956	 the Certifying Officer and the appellate authority are bound to examine the question of fairness of the standing orders	 and therefore	 there can be no justification now for not giving effect to the principle of uniformity of conditions of service which is clearly contemplated by the provisions of the Act. [763 D F] (3) But cl. 32 of the Standing Orders as certified in 1951 was not valid and could not be binding on the respondents	 because	 there was then 'no item in the Schedule to the Act covering cases of superannuation or retiretirement	 with respect to which Standing Orders could be made. [766 E F	 G H] Item 8 and 9 of the Schedule deal with the termination of employment and notice thereof	 and suspension or dismissal for misconduct. The language of item 8 shows that it does not cover the case of superannuation	 which does not depend on )any notice and which covers an event which is automatic and which must be given effect to without any volition on the Part of the employer or workmen. If termination is to be read in a wide sense as meaning 'employment coming to an end ' there was no necessity to have item 3	 because	 dismissal would then be covered by termination. From the paragraph 13 of the Model Standing Orders contained in the Schedule to Rules it is apparent that item 8 is confined to termination of employment by notice in writing and 'does not refer to superannuation or retirement. It was only in 959 that item 11(C) was introduced in the Schedule enabling the framing of Standing Orders in relation to the age of retirement and superannuation. [765 F H; 766 A C] Saroj Kumar vs Orissa State Electricity Board	 A.I.R. 1970 Orissa	 126	 approved. Management of the Windu ' vs Secretary Hindu Office & National Press Employees Union	 	 disapproved. (4) No assistance can be derived by the use of the word 'retirement ' in para	 16 of the Model Standing Orders	 because	 it may well refer to 756 retirement under the terms of the contract of employment entered into between the employer and the employees. [765 A B	 E] (5) Since before the amendment of section 4 the Certifying Officer and the appellate auhority were debarred from adjudicating upon	 the fairness or reasonableness of the Standing Orders	 the Certifying Officer at that time	 could not certify any Standing Order on the ground that it was reasonable or fair. Therefore	 in 1951	 when the Standing Orders were certified	 cl. 32 could not have been framed because there was no item in the Schedule relating to superannuation and the Certifying Officer could not certify it on the ground it was fair and reasonable because he bad no power to do so. [766 D F] (6) The Certifying Officer	 however	 when be modified cl. 32 and fixed the retirement age at 58 (after section 4 was amended) could have validly certified such clause as modified by him. This Court could also give an appropriate direction with regard to fixing the age of superan 	 nuation. In the circumstances of this case the age of superannuation should be 58 years. Therefore	 the concerned workman should be deemed to have continued in service of the appellant till they had attained the age of 58 years. [767 A C	 G H] (7) The order of the High Court in the writ petition did not finally termingte the proceedings at all. The proceedings were terminated only by the award of the Industrial Tribunal after remand. Therefore	 the order of the High Court following Guest Keen William 's case did not debar a fresh consideration of the question by virtue of the rule or principle of res judicata.
