Summarize the following court judgment. Appeal No. 13 of 1963. Appeal by special leave from the award dated January 20	 1962	 of the Industrial Tribunal No. 307 of 1961. M.C. Setalvad and A.N. Goyal. for the appellant. B.P. Maheshwari and O.P. Singh for the respondent. November 14	 1963. The Judgment of the Court was delivered by GAJENDRAGADKAR J. The short question of law which arises in this appeal by special leave relates to the construction of section 25 FF of the (No. 14 of 1947) (hereinafter called 'the Act ') This question arises in this way. Between the appellant	 the Management of R.S. Madhoram & Sons (Agencies) (P) Ltd.	 and the respondents	 its workmen an Industrial dispute arose in regard to the transfer of 57 employees from the management of R.S. Madho ram & Sons	 which was their original employer	 to the appellant. This dispute was referred for adjudication by the Delhi Administration to the Industrial Tribunal	 New Delhi. The case of the respondents was that the impugned transfer is invalid	 whereas the appellant contended that the said transfer was fully valid and justified under section 25FF of the Act. Certain other pleas were 381 raised by the parties before the Tribunal and they have been considered by it	 but it is not necessary for the purpose of the present appeal to refer to them	 since the only point which has been urged betoken us by Mr. Setalvad on behalf of the appellant is in relation to the finding of the Tribunal that section 25FF does not apply to the present case. R.S. Madhoram & Sons	 and R.S. Madhoram & Sons (Agencies) (P) Ltd. are the two concerns involved in this dispute. The first is a firm consisting of the members of a joint Hindu family and the second is a company formed by the said members. The firm has been in existence since April 1	 1946 whereas the company came into existence on August 29	 1961. The head office of the firm is at Dehra Dun and it runs branches at Delhi	 New Delhi	 Mussoorie and Amritsar. The firm acts as selling representatives of Obeetee (Private) Ltd.	 Mirzapur: Commonwealth Trust Ltd.	 Calicut	 and United Coffee Supply Co. Ltd.	 Coimbatore. It also acts as Government contractors as well as stockists of the Elgin Mills Co. Ltd.	 Kanpur. The 57 employees whose transfer from the firm to the company has given rise to the present dispute were originally employed by the firm. On the muster roll of the firm	 92 employees were entered. Out of these	 57 have been transferred by the firm to the company as a result of the agreement between the two concerns. The company was formed as a separate and different concern	 and in accordance with its memorandum and articles of association and in pursuance of the agreement between it and the firm	 it has taken over the retail business of the firm together with the staff employed by the firm in the said retail business as from September 15	 1961. The agreement shows that when the staff was taken over by the company from the firm	 continuity of service was guaranteed to the staff and the terms and conditions of service enjoyed by them before the taking over also remained unaffected. The appellant contends that it is the successor in interest of the firm in regard to the retail business 382 which was one of the businesses carried on by the firm	 and it argues that since the conditions prescribed by the proviso to section 25FF have been complied with	 the grievance made by the respondents that the transfer of the 57 workmen in question is unjustified cannot be sustained. On the other hand	 the respondents contend that section 25FF is inapplicable to their case	 because the ownership or management of the undertaking has not been transferred by the firm to the company within the meaning of the said section. If the said section does not apply	 then there is no scope for applying the provisions of the proviso. The Tribunal has upheld the plea raised by the respondents	 and Mr. Setalvad contends that the finding of the Tribunal is based on a misconstruction of section 25FF of the Act. Before dealing with this point	 it would be useful to refer to the relevant facts which preceded the transfer of 57 employees. It appears that on September 14	 1961	 there was an agreement between the transferor and the transferee as a result of which the employees engaged by the transferor were transferred to the transferee company. This agreement provided that the service of the said workmen shall not be interrupted by reason of the transfer	 that the terms and conditions of service applicable to the said workmen shall not be less favorable than those applicable to them immediately before the transfer	 and that the transferee concern shall be liable to pay to the workmen in the event of their retrenchment	 compensation on the basis that their service had been continuous and had not been interrupted by the transfer. Another agreement was executed between the firm and the company on September 15	 1961	 as a result of which the company took over the entire retail business hitherto run by the firm. Clauses 2 to 5 of the said agreement provide the other terms and conditions subject to which the transfer of the retail business was effected between the firm and the company. 383 After this transaction was thus completed between the firm and the company	 notice was issued to the workmen in question intimating to them that as a result of the transfer their services would be taken over by the transferee company. These workmen were told that in computing the length of their service	 the period of their service with the transferor firm would be taken into account. They were also told that if any of them did not want to work with the transferee company	 they should intimate accordingly to the said company within three days from the receipt of the notice whereupon their legal dues would be paid to them. For reasons which it is not easy to understand or appreciate	 the respondent Union representing the appellant 's employees does not appear to have responded favourably to this notice and correspondence that passed between the respondent and the appellant shows that the workmen were not prepared to be treated as the employees of the transferee company. It seems that they were willing to do the work of retail business which had been transferred to the company	 but they were unwilling to forego the status as the employees of the transferor firm. Attempts at conciliation were made	 but the differences between the parties could not be resolved	 and so	 the matter ultimately went to the Industrial Tribunal for its adjudication. That is bow the only question which arises for our decision is whether section 25FF and its proviso apply to the present case. Section 25FF of the Act provides	 inter alia	 that where the ownership or management of an undertaking is transferred	 whether by agreement or by operation of law	 from the employer in relation to that undertaking to a new employer	 every workman who satisfies the test prescribed in that section shall be entitled to notice and compensation in accordance with the provisions of section 25FF as if the workman had been retrenched. This provision shows that workmen falling under the category contemplated by it	 are entitled to claim retrenchment compensation in 384 case the undertaking which they were serving and by which they were employed is transferred. Such a transfer 	 in law	 is regarded as amounting to retrenchment of the said workmen and on that basis section 25FF gives the workmen the right to claim compensation. There is	 however	 a proviso to this section which. excludes its operation in respect of cases falling under the proviso. In substance	 the proviso lays down that the provision as to the payment of compensation on transfer will not be applicable where in spite of the transfer	 the service of the workmen has not been interrupted. The terms and conditions of service are not less favorable after transfer then they were before such transfer	 and the transferee is bound under the terms of the transfer to pay to the workmen in the event of their retrenchment	 compensation on the basis that their service had been continuous and had not been interrupted by the transfer. The proviso	 therefore	 shows that where the transfer does not effect the terms and conditions of the employees	 does not interrupt the length of their service and guarantees to them payment of com pensation	 if retrenchment were made	 on the basis of their continuous employment	 then section 25FF of the Act would not apply and the workmen concerned would not be entitled to claim compensation merely by reason of the transfer. It is common ground that the three conditions prescribed by clauses (a) (b) and (c) of the proviso are satisfied in this case and so	 if section 25FF were to apply	 there can be little doubt that the appellant would be justified in contending that the transfer was valid and the 57 employees can make no grievance of the said transfer. The question	 however	 is: does section 25FF apply at all? It would be noticed that the first and foremost condition for the application of section 25FF is that the ownership or management of an undertaking is transferred from the employer in relation to that undertaking to a new employer. What the section contemplates is that either the ownership or the management of an undertaking should be transferred; normally this would 385 mean that the ownership or the management of the entire undertaking should be transferred before section 25FF comes into operation. If an undertaking conducts one business	 it would normally be difficult to imagine	 that its ownership or management can be partially transferred to invoke the application of section 25FF. A business conducted by an industrial undertaking would ordinarily be an integrated business and though it may consist of different branches or departments they would generally be inter related with each other so as to constitute one whole business. In such a case	 s.25FF would not apply if a transfer is made in regard to a department or branch of the business run by the undertaking and the workmen would be entitled to contend that such a partial transfer is outside the scope of section 25FF of the Act. It may be that one undertaking may run several industries or businesses which are distinct and separate. In such a case	 the transfer of one distinct and separate business may involve the application of section 25FF. The fact that one undertaking runs these businesses would not necessarily exclude the application of section 25FF solely on the ground that all the businesses or industries run by the said undertaking have not been transferred. It would be clear that in all cases of this character the distinct and separate businesses would normally be run on the basis that they are distinct and separate; employees would be separately employed in respect of all the said businesses and their terms and conditions of service may vary according to the character of the business in question. In such a case	 it would not be usual to have one muster roll for all the employees and the Organisation of employment would indicate clearly the distinctive and separate character of the different businesses. If that be so	 then the transfer by the undertaking of one of its businesses may attract the application of section 25FF of the Act. But where the undertaking runs several allied businesses in the same place or places	 different 1/SCI/64 25 386 considerations would come into play. In the present case	 the muster roll showing the list of employees was common in regard to all the departments of business run by the transferor firm. it is not disputed that the terms and conditions of service were the same for all the employees and what is most significant is the fact that the employees could be transferred from one department run by the transferor firm to another department	 though the transferor conducted several branches of business which are more or less allied	 the services of the employees were not confined to any one business	 but were liable to be transferred from one branch to another. In the payment of bonus all the employees were treated as constituting one unit and there was thug both the unity of employment and the identity of the terms and conditions of service. In fact	 it is purely a matter of accident that the 57 workmen with whose transfer we are concerned in the present appeal happened to be engaged in retail business which was the subject matter of the transfer between the firm and the company. These 57 employees had not been appointed solely for the purpose of the retail business but were in charge of the retail business as a mere matter of accident. Under these circumstances	 it appears to us to be very difficult to ' accept Mr. Setalvad 's argument that because the retail business has an identity of its own it should be treated as an independent and distinct business run by the firm and as such	 the transfer should be deemed to have constituted the company into a successor in interest of the transferor firm for the purpose of section 25FF. As in other industrial matters	 so on this question too	 it would be difficult to lay down any categorical or general proposition. Whether or not the transfer in question attracts the provisions of section 25FF must be determined in the light of the circumstances of each case. It is hardly necessary to emphasise that in dealing with the problem	 what industrial adjudication should consider is the matter of substance and not of form. As has been observed by this Court in Anakapalla Cooperative Agricultural and In 387 dustrial Society vs Workmen and others(1) the question as to whether a transfer has been effected so as to attract section 25FF must ultimately depend upon the evaluation of all the relevant factors and it cannot be answered by treating any one of them as of overriding or conclusive significance. Having regard to the facts which are relevant in the present case	 we are satisfied that the appellant cannot claim to be a successor in interest of the firm so as to attract the provisions of section 25FF of the Act. The transfer which has been affected by the firm in favour of the appellant does not	 in our opinion	 amount to the transfer of the ownership or management of an undertaking and so	 the Tribunal was right in holding that section 25FF and the proviso to it did not apply to the present case. The result is	 the appeal fails and is dismissed with costs. Appeal dismissed.

An industrial dispute arose between the appellant the Management of R.S. Madhoram & Sons (Agencies) (P) Ltd.	 and the respondents its workmen	 in regard to the transfer of 57 employees from the Management of R.S. Madhoram & Sons	 which was there original employer	 to the appellant. By agreement the transferor firm transferred its retail business to the appellant. This dispute was referred for adjudication to the Industrial Tribunal. The case of the respondents was that section 25FF is inapplicable to their case	 because the ownership or management of the undertaking has not been transferred by the firm to the company within the meaning of that section. The case of the appellant was that the said transfer was fully valid and justified under section 25FF of the Act. In the present case	 the muster roll showing the list of employees was common in regard to all the departments of business run by the transferor firm. The employees could be transferred from one department run by the transferor firm to another department. In the payment of bonus all the employees were treated as constituting one unit and there was thus both the unity of employment and the identity of the terms and conditions of service. The respondents succeeded before the Tribunal. The appellant has come to this Court against the award of the Tribunal. Held: (i) The first and foremost condition for the appli cation of section 25FF is that the ownership or management of an undertaking is transferred from the employer in relation to that undertaking to a new employer. Normally this would mean that the ownership or the management of the entire undertaking should be transferred before section 25FF comes into operation. If an undertaking conducts one business it would normally be difficult to imagine that its ownership or management can be partially transferred to invoke the application of section 25FF. It may be that one undertaking may run several industries or businesses which are distinct and separate. In such a case	 the transfer of one distinct and separate business may involve the application of section 25FF. On the facts of this case it was held that the retail business of the transferor firm was not a separate and distinct business and as such	 the impugned transfer did not amount to the transfer of 380 the ownership or management of an undertaking so as to attract the provisions of section 25FF of the Act. In the present case. the appellant cannot claim to be a successor in interest of the firm so as to attach section 25FF of the Act. (ii)It would be difficult to lay down any categorical or general proposition as to the application of section 25FF. Whether or not the transfer in question attracts the provisions of section 25FF must be determined in the light of the circumstances of each case. The question as to whether a transfer has been effected so as to attract section 25FF must ultimately depend upon the evaluation of all the relevant factors and it cannot be answered by treating anyone of them as of over riding or conclusive significance.
