Summarize the following court judgment. ISDICTION: Civil Appeal No. 3092 of 1985 etc. From the Judgment and Order dated 1.2.1985 of the Alla habad High Court in W.P. No. 1535 of 1972. 338 S.N. Kacker	 R.B. Mehrotra	 Gopal Subramanium	 Mrs. section Dixit	 section Balakrishnan and Ifran Ahmad for the Appellants. T.S. Krishnamoorthi Iyer	 Mukul Mudgal	 section Balakrishnan and Rajesh for the Respondents. The Judgment of the Court was delivered by KHALID	 J. This appeal by special leave and the connect ed special leave petition and the writ petition directed against the judgment and order of the Allahabad High Court dated February 1	 1985 raise a question of construction of Regulation 7(iv)(b) of the U.P. State Electricity Board Service of Engineers (Integration & Seniority) Regulations	 1976	 framed under section 79(c) of the . By the judgment	 a Division Bench of the High Court has disallowed a batch of writ petitions seeking to quash an order of the U.P. Public Services Tribunal	 Lucknow dated April 3	 1978. Allowing a representation made by respondent No. 1	 presently working as Superintending Engineer in the U.P. State Electricity Board	 the Tribunal held that in terms of Regulation 7(iv)(b) of the Regulations	 respondent No. 1 having been granted seven advance increments was entitled to the benefit of as many years of service as the number of advance increments given to him at the time of his recruitment. The High Court has upheld the order of the Public Services Tribunal. As a result	 respondent no.1 who figures at serial No. 12 in the integrated seniority list of Assistant Engineers (Civil) i.e. below other Superintending Engineers including the six petitioners in the connected special leave petition No. 8835/85	 would take his place at serial no.1 in the seniority list i.e. above them. The short question involved in this appeal is whether respondent No. 1 on a proper construction was entitled to the benefit of as many years of service as the number of advance increments given to him at the time of his recruit ment	 as held by the Public Services Tribunal and the High Court. That turns on a construction of the amended Regula tion 7(iv)(b) of the Regulations. Regulation 7(iv)(b) as originally framed provided: "While determining the seniority under clauses (ii) and (iii) above	 Engineers directly recruited by the Board before the commencement of these regulations shall be given advantage of as many years of service as is the number of advance increments which were allowed to them at the time 339 of recruitment by the Board. In doing so	 no officer shall however be given advantage beyond the date of his initial regular ap pointment in the Government department or the other organisations. " On June 19	 1976 the Electricity Board in exercise of the powers under section 79(c) of the amended Regulation 7(iv)(b) to remove certain anomalies and to give effect to the intention or ' the Board in framing the rule of seniority. It was felt by the Board that the expres sion 'other organisations ' in the unamended Regulation 7(iv)(b) was susceptible of a construction that in the matter of determination of inter se seniority among directly recruited Engineers vis a vis Engineers on deputation with the Board from the Central Government or the State Govern ment	 the seniority of the Engineers had to be reckoned by giving them the benefit of as many years of service as the number of advance increments given to them by reason of their special experience or qualifications. The Board ac cordingly substituted the words 'U.P. or Central Government Department in consideration of the service for which advance increments were so allowed ' for the words 'Government de partment or other organisations ' in Regulation 7(iv)(b). The amended Regulation 7(iv)(b) now provides: "While determining the seniority under clauses (ii) and (iii) above	 Engineers directly recruited by the Board before the commencement of these regulations shall be given advantage of as many years of service as is the number of advance increments which were allowed to them at the time of recruitment by the Board. In doing so	 no officer shall however be given advantage beyond the date of his initial regular appointment in the U.P. or Central Government Department in consideration of the service for which advance increments were so allowed. " Put very briefly	 the essential facts are these. By a Government resolution dated March 30	 1959 all the officers of State Government i.e. Civil Engineers and the Electrical and Mechanical Engineers of the Irrigation & Power Depart ment were transferred to the U.P. State Electricity Board constituted under section 5 of the which came into existence on April 1	 1959. The services of these officers were placed on deputation with the Board. In 1964	 the Electricity Board issued an advertisement calling for applications for appointment to 20 posts of Assistant Engineers (Civil). It was indicated that a higher start would be allowed to candidates with special qualifi 340 cations or experience and that the selected candidates were to become permanent on completion of three years ' probation. Among those selected was respondent No. 1 P.L. Kelkar who by reason of his previous experience was given a higher start of Rs. 490 in the scale of Rs. 250 850 which meant that he was given nine advance increments as against two increments given to others. Prior to his joining the Electricity Board	 respondent no.1 had varied experience in different govern mental and other organisations. After obtaining his degree in Bachelor of Engineering in the year 1957	 he was recruit ed as a Junior Engineer	 Public Works Department (Building) of the State of Madhya Pradesh on a scale of Rs. 150 300. In 1959 he was promoted as Assistant Engineer	 Department of Housing	 Madhya Pradesh on a scale of Rs. 250 600. Thereaf ter on June 9	 1960 he accepted appointment as Engineering Assistant Grade I in the Indian Refinery Limited	 Guwahati	 a Government of India undertaking	 on a scale of Rs.300525 after leaving the services of the State Government of Madhya Pradesh. On May 10	 1961	 he left Government service to take up employment in the private sector as Assistant Civil Engineer with the Associated Cement Company Limited	 Bombay on an initial salary of Rs. 305 per month with annual incre ments. After the interviews of the candidates held on August 17	 1964	 the Board in its letter of appointment dated August 22	 1964 offered respondent No. 1 two advance incre ments and stated that his seniority vis a vis the other candidates selected for appointment would be determined later. It seems that respondent No. 1 declined the offer and accordingly the Board by its letter dated August 29	 1964 decided to grant him a higher initial pay of Rs.490 i.e. nine advance increments because of his previous experience. It may be mentioned here that the Board also granted a higher initial pay of Rs.490 i.e. nine advance increments to Prakash Chandra Jain and Rs.430 i.e. seven advance incre ments to Naresh Chandra Gupta. As against respondent No. 1 who had been directly re cruited by the Board w.e.f. October 7	 1964 and is now working as a Superintending Engineer in the Electricity Board	 the six petitioners in the connected special leave petition No. 8835/85 namely	 V.N. Mathur	 Mohd. Wasi Ahmad	 Madan Mohan	 Brajesh Sahai	 Amba Prasad and O.P. Sharma who are also now working as Superintending Engineers in the Electricity Board were Assistant Engineers in the Irrigation & Power Department	 were placed on deputation with the Board by the State Government from the year 1960 onwards. They were in due course confirmed as Assistant Engineers in the Irrigation & Power Department. It seems that respondent No. 1 as well as the petitioners were 341 confirmed as Assistant Engineer w.e.f. April 1	 1975. There was no seniority list of Assistant Engineers in the Board nor any rules of seniority at the time when respondent No. 1 joined service. On April 29	 1976 the Board in exercise of the powers under section 79(c) of the framed the U.P. State Electricity Board Service of Engineers (Integration & Seniority) Regulations	 1976. As already stated	 the unamended Regulation 7(iv)(b) provided that while determining seniority	 Engineers directly re cruited by the Board before the commencement of the Regula tions shall be given advantage of as many years of service as was the number of advance increments which were allowed to them at the time of their recruitment i.e. although respondent No. 1 was recruited on October 7	 1964	 it should be deemed that he joined service of the Board on October 7	 1957. As a result of this representation the Board was constrained to amend Regulation 7(iv)(b) as indicated above. On May 19	 1977 the Board rejected the representation made by respondent No. 1. A few months thereafter i.e. on Septem ber 28	 1977 the Board in acccordance with the amended Regulation 7(iv)(b) published the integrated seniority list in which the name of respondent No. 1 figures at serial No. 12 i.e. below other officers at present working as Superin tending Engineers including the aforesaid petitioners in the connected special leave petition. We however wish to mention that there is a controversy as to whether the petitioners in the connected special leave petition applied for and were not selected by the Board as Assistant Engineers (Civil) in 1968. Respondent No. 1 P.L. Kelkar has averred in paragraphs 7	 8 and 9 of the counter affidavit that the aforesaid petitioners who were working on deputation with the Electricity Board did not consider it beneficial to leave their parent department viz. Irrigation & Power Department and join the services of the Board at the relevant time although the Board had again advertised the posts of Assistant Engineer (Civil) in the year 1965. He then goes on to aver in paragraph 9 that in order to build up the Civil Engineering cadre of the Board the Electricity Board readvertised the posts of Assistant Engineer (Civil) in the year 1968 and asserts that most of the petitioners applied for the post and the selection was made by a Selec tion Board on the basis of interview and record of past service and adds: "However	 all the petitioners except petition ers nos. 4 and 5 Panba Prasad and O.P. Sharma were not selected for the post of Assistant Engineer (Civil) as per the selection list published by the Board. The reason for the non selection 342 was obviously that they were not found fit for the post on the basis of their record and interview. " When this averment was brought to our notice by learned counsel for respondent No. 1 we called upon the Electricity Board to place before us the relevant records relating to the interviews held in the year 1968 and also to file a detailed affidavit. Learned counsel for the Electricity Board assured us that the Board will comply with the direc tion and place before the Court the relevant records and also file an affidavit. Learned counsel for the petitioners in the connected special leave petition however was baffled at the suggestion that the petitioners should have at all applied for the post of Assistant Engineer (Civil) adver tised in the year 1968 when they were for a number of years actually functioning as officiating Executive Engineers in the Irrigation and Power Department. To set the matter at rest	 we asked the parties to exchange affidavits on the subject although the hearing concluded on March 24	 1987 and the case was reserved for judgment. On April 3	 1987 M.S. Rizvi	 Deputy Secretary	 U.P. State Electricity Board has sworn an affidavit bringing the relevant facts on record. It is averted in paragraph 2 that the records in possession of the Board revealed that in July 1968 applications for the posts of Assistant Engineer (Civil) in the service of the U.P. State Electricity Board were invited and that inter views of the candidates who had applied in pursuance of the said advertisement were conducted during December 1968 and January 1969. In paragraph 3 the respective dates of promo tion of the petitioners as Executive Engineers are given. In paragraph 4 however it is stated that the records relating to the applications in the interviews are not traceable inspite of the best efforts made by the senior officers of the Electricity Board. In his rejoinder	 respondent No. 1 P.L. Kelkar contro verts the facts alleged. He submits that the affidavit filed by the Electricity Board does not state the facts correctly. It is then stated: "In fact in Petition No. 4888 (F) III/77 filed by Shri N.P. Malik & Ors. vs U.P. State Elec tricity Board it was averted in para 11 as follows: "That respondents Nos. 2 to 15 applied against advertisement for selection of direct recruits as Civil Engineers in 1968. After an interview they were found to be unfit and were not selected for the substantive post. The list of 343 persons selected under section 3.0. No. 2208 A/SEB/159 A/1968 dated 1.4.69 shows that they were not selected. "In reply to the above submission in paragraph 11	 it was averred by the Board before the Public Services Tribunal that the 'contents of paragraph 11 are admitted. " In view of the above reply	 respondent No. 1 submits that it is wholly irrelevant whether the records are now available or not because the above affidavit in the Public Services Tribunal was made after perusing the records. We are rather surprised that the Electricity Board should file an affidavit by the Deputy Secretary stating that the rele vant records of the interviews held in the year 1968 are not available unless they have been done away with. We have given above the necessary back ground facts for appreciating the dispute involved in these cases. A decision in these cases depends upon the correct interpretation of Regulation 7(iv)(b) before and after its amendment. The regulation comprises of two parts. The first part refers to the advantage of advance increments. This advantage is based on special qualification and past experience and its conse quent effect on seniority. The grant of subsequent incre ments by the Board after joining its service is not governed by	this regulation. It is the second part of the regulation that gives a little difficulty and it was on this that considerable arguments were addressed before us. Special reliance was placed upon the expression 'in doing so ' occurring in the regulation. What is contended is that this expression indi cates the manner in which the first part is to be construed. The regulation	 before its amendment mentioned Government departments or other organisations but after its amendment it was changed to 'in the U.P. or Central Government Depart ment '. This change shows a deliberate attempt to deny its benefit to employees who came from service not comprised in either U.P. or Central Government departments. We do not think that it would be either just or fair to give a limited meaning to the second part of the amended regulation and thereby to deny its benefit to those Engineers who came from other departments or corporations etc. It is necessary to note that the first part of the regulation does not speak of Engineers in the U.P. or the Central Government Departments. It speaks only of Engineers directly recruited by the Board before the commencement of this regulation	 which expression takes in	 Engineers who came into the service of the 344 Board from all sources. That being so	 it would not be proper to completely eliminate Engineers who came from other sources from the benefit of the regulation giving a re stricted meaning to the expression 'in doing so '. It is useful to note. that the Board 's advertisement inviting applications provided higher start for those having special qualifications and experience irrespective of the source of the service held by them. The second part of the regulation has therefore to be construed only as a proviso to the first part confining its scope to the employees of the U.P. as well as Central Government and not to affect the generality as contemplated in the first part. The injustice that will be meted out to the Engineers who came from outside if the restricted meaning is given to the second part of the regulation	 can be best illustrated by referring to the case of Shri P.L. Kelkar. He was ap pointed as a Junior Engineer	 P.W.D.	 M.P. on July 19	 1957 and was promoted as Assistant Engineer and posted in Housing Department on May 20	 1959. On June 9	 1960 he was appointed Engineer Assistant Grade I in Indian Refinery Limited	 Guwahati	 after leaving the services of the M.P. Government. Thereafter	 he was appointed as Assistant Engineer on May 10	 1961	 in Associated Cement Company Limited	 Bombay. It was while working in that company that he came across the advertisement made by he U.P. State Electricity Board. He applied pursuant to such advertisement. He was selected by the Board and appointed as per order dated August 22	 1964. He joined service on October 7	 1964. He was given nine increments taking into consideration his special qualifica tion and experience. Two increments were common to all. Thus	 the extra increments given to him were seven. It is apparent that if this extra increment on the basis of his experience and special qualification did not carry with it	 seniority in the Board	 he would not have either applied or accepted the job. It cannot be assumed that he would have joined the Board willingly as a new entrant. Under these circumstances	 the Tribunal was justified in holding that he should be deemed to have been appointed w.e.f. October 7	 1957	 instead of October 7	 1964	 when he joined the service of the Board. The Tribunal according to us justifiably repelled the contention that he was not entitled to the above advantage under the second part of the Regulation 7(iv)(b). In our view	 the Tribunal was justified also in holding that second part is in the nature of proviso limited to persons who had been in service of either U.P. or the Central Government Departments and who had been given ad vance increments in consideration of such service. The High Court considered the question in detail with refer ence 345 to the regulation under consideration and agreed with the Tribunal in the construction put by it regarding the second part of the regulation. We have also given our anxious consideration to the regulation before and after the amend ment. We also come to the conclusion that the interest of justice will be advanced by agreeing with the High Court and the Tribunal in the construction given by them to this regulation. In our judgment	 therefore	 seniority will have to be fixed in accordance with the number of increments excluding the original two increments given to the entrants in the Board both from the U.P. and the Central Government Departments and from other sources. We do not think it necessary to answer other aspects of the case for this judgment. We do not think any interference is called for with the judgment of the High Court. We confirm the judg ment	 dismiss the appeal	 writ petition and the special leave petition	 with no order as to costs. N.P.V. Appeal and Petitions dis missed.

The first respondent in the Appeal	 a Superintending Engineer	 was directly recruited by the U.P. Electricity Board as an Assistant Engineer on October 7	 1964. He was given nine advance increments by reason of his varied expe rience in different governmental and other organisations	 as against two advance increments given to others. The peti tioners in the connected special leave petition also working as Superintending Engineers were Assistant Engineers in the Irrigation and Power Department and were placed on deputa tion with the Electricity Board by the State Government from the year 1960 onwards	 and were confirmed as Assistant Engineers with effect from April 1	 1975. There was no seniority list of Assistant Engineers in the Board nor were there any rules of seniority at the time when the first respondent joined service. The Electricity Board	 in exercise of the power con ferred under section 79(c) of the framed the U.P. Electricity Board Service of Engineers (Integration and Seniority) Regulations 1976. Regulation 7(iv)(b) provided that ' 'while determining the seniority under clauses (ii) and (iii)	 Engineers directly recruited by the Board before the commencement of these regulations shall be given advantage of as many years of service as was the number of advance increments which were allowed to them at the time of recruitment by the Board. " It also provided that "in doing so	 no officer shall	 however	 be given advantage beyond the date of his initial regular appointment in the Government department or the other organisations. " The Board amended the regulation to remove certain anomalies and to give effect to the intention of the Board in framing the rule of seniority. The amended regulation substituted the words "U.P. 336 C.R. Government or Central Government Department in consideration of the service for which advance increments were so allowed." The Board	 in accordance with the amended regulation	 published the integrated seniority list in which the name of the first respondent figured at SI. No. 12 below other officers working as Superintending Engineers including the petitioners in the connected special leave petition. The first respondent made a representation to the U.P. Services Tribunal challenging the amended regulation which was allowed. The Tribunal held that in terms of Regulation 7(iv)(b) of the Regulations	 the first respondent having been granted seven advance increments was entitled to the benefit of as many years of service as the number of advance increments given to him at the time of his recruitment. A batch of writ petitions seeking to quash the order of the Tribunal was filed in the High Court	 which upheld the order of the Tribunal. The Appeal by special leave by the Electricity Board	 the connected Special Leave Petition of the aggrieved peti tioners and the Writ Petition challenged the construction and application of Regulation 7(iv)(b). Dismissing the Appeal	 the Special Leave Petition and the Writ Petition	 the Court HELD: (1) Regulation 7(iv)(b) of the U.P. State Elec tricity Board of Service of Engineers (Integration and Seniority) Regulations	 1976 comprises of two parts. The first part referred to the advantage of advance increments. This advantage is based on special qualification and past experience and its consequent effect on seniority. The Regulation before its amendment	 mentioned 'Government departments or other organisations ' but after its amendment it was changed to 'in the U.P. or Central Government Depart ment. ' This change showed a deliberate attempt to deny its benefit to employees who came from service not comprised in either U.P. or Central Government Departments. It would be neither just nor fair to give a limited meaning to the second part of the amended regulation and thereby to deny its benefit to those Engineers who came from other depart ments or corporations etc. [343D F; 344B] 2. The first part of the regulation does not speak of Engineers in the U.P. or Central Government Departments. It speaks only of Engineers 337 directly recruited by the Board before the commencement of the regulation	 which expression takes in	 Engineers who came into the service of the Board from all sources. It would not be proper to completely eliminate Engineers who came from other sources from the benefit of the regulation giving a restricted meaning to the expression 'in doing so '. [343H; 344A] 3. The Board 's advertisement in the instant case	 invit ing applications provided higher start for those having special qualifications and experience irrespective of the source of the service held by them. The second part of the regulation has	 therefore	 to be construed only as a proviso to the first part confining its scope to the employees of the U.P. as well as Central Government Departments and not to affect the generality as contemplated in the first part. [344B] 4. The Tribunal was right in holding	 and the High Court in agreeing with it	 that the second part was in the nature of proviso limited to persons who had been in service of either U.P. or other Central Government Departments and who had been given advance increments in consideration of such service. [344G H] 5. In the instant case	 the first respondent was given nine increments taking into consideration his special quali fication and experience as against two increments common to all	 and thus	 giving him seven extra increments. It is apparent that if these extra increments on the basis of his experience and special qualification did not carry with it seniority in the Board	 he would not have either applied or accepted the job. It cannot be assumed that he would have joined the Board willingly as a new entrant. Under these circumstances. the Tribunal was right in holding that the first respondent should be deemed to have been appointed with effect from October 7	 1957	 giving him the advantage of extra increments under the second part of Regulation 7(iv)(b). The seniority will have to be fixed in accordance with the number of increments excluding the original two increments given to the entrants in the Board both from U.P. and the Central Government Departments and from other sources.
