Summarize the following court judgment. ivil Appeal No. 651 of 1976. (Appeal by Special Leave from the Judgment and Order dated 19 6 1974 of the Bombay High Court in S.C.A. No. 1251 of 1970.) M.N. Phadke	 Girish Chandra and M.N. Shroff	 for the appellants. S.V. Gupte	 N. Kamalakar and A.G. Ratnaparkhi	 for the respondent. The Judgment of the Court was delivered by CHANDRACHUD	 J. On the reorganisation of States on November 1	 1956 the respondent who was working as an Agri cultural Overseer in the then State of Madhya Pradesh was allocated first to the State of Bombay and later to the State of Maharashtra. By a resolution dated February 17	 1958 the Government of Bombay equated the post of Agricul tural Overseer with that of an Agricultural Assistant	 Grade II. In July 1958 the respondent was promoted as an Agricul tural Supervisor and in April 1967 he was appointed to the post of an Agricultural Officer. On the reorganisation of States	 a provisional combined seniority list of Agricultural Assistants	 Grade II	 was published by the Government of Maharashtra in 1961. That list was revised from time to time	 and ultimately the Government of India approved the final seniority list which came to be published on May 29	 1973. The respondent has no grievance against ' his placement in that list	 but his case is that under the seniority lists prepared from time to time by the State Government	 he was erroneously accorded a lower place of seniority with the result that persons who were in fact junior to him came to be promoted on the assumption that they were senior to him. The respondent therefore filed the present writ petition on October 14	 1970 asking for due recognition of his seniority. He later amended that peti tion and asked for arrears of pay and allowances retrospece tively from the date on which he ought to have been promoted in accordance with the seniority list approved by the Cen tral Government. The writ petition having been allowed by the Nagpur Bench of the Bombay High Court	 the State of Maharashtra has filed this appeal by special leave. The sole question which arises for determination in this appeal is whether the respondent is entitled to arrears of pay with effect from the date on which he would	 in the normal course	 have been promoted if his seniority Were recognised as it eventually came to be 589 recognised under the seniority list approved by the Central Government in 1973. The answer to this question depends on whether the rights of the respondent are governed by the circular dated March 10	 1960 or by the circular dated February 25	 1965. The case of the State Government is that the former	 and not the latter circular	 applies whereas the respondent contends that he is entitled to arrears of salary for the entire period under the latter circular. We find it impossible to accept the respondent 's conten tion	 which has found favour with the High Court	 that the circular of February 25	 1965 governs the matter. That circular reads thus: "Retrospective promotions of those who had been superseded earlier. GOVERNMENT OF MAHARASHTRA GENERAL ADMINISTRATION DEPARTMENT Circular Memorandum No. SRV 1064 .D	 Sachiva laya	 Bombay 32 (B.R.) 25th February	 1965/Falgune 6	 1886. CIRCULAR MEMORANDUM OF GOVERNMENT A question has been raised whether in cases in which Government servants who were super seded for promotion to the higher post are later promoted on the orders of higher author ities who consider the supersession unjusti fied and who having powers to set aside the order of supersession	 do so	 their promotion should be effective from the date on which they are actually promoted or from the date they should have been promoted had they not been wrongly superseded. The Government has	 considered this question and decided that in such cases	 the Government servants concerned	 should be deemed to have been promoted to higher post from the date from which they would have been promoted	 but for their wrong ful supersession i.e. from the date from which their juniors who were promoted by superseding them started to officiate in such posts and they should be allowed pay in such post as if they were promoted on the dates on which their juniors were promoted and also paid arrears of pay and allowances from such dates. (2) Orders in paragraph 1 above apply also to the cases of persons	 who are superseded for promotion to gazetted post within the pur view of the Public Service Commission ordered by Government but are later promoted when their earlier supersession is considered in consultation with the Commission unjustified. (3) Pending cases should be regulated in accordance with these orders in paragraphs 1 and 2 above	 and arrears of 590 pay and allowances should be paid to the persons concerned provided that if the arrears relate to any period prior to the 1st May 1960	 the payment is restricted to the period after that date	 i.e. after the st May 1960. (4) This Circular Memorandum issues with the concurrence of the Finance Department VIDE that department unofficial reference No. 581/V	 dated the 2nd February	 1965. By Order and in the name of Government of Maharashtra. Sd/ K.P. Nadkarni	 Deputy Secre tary to Govt. " The language of this circular is singularly inappropriate to cover cases concerning equation and seniority consequent upon formation of new States. The circular deals with cases where government servants who are superseded for promotion to the higher post are later promoted on orders of higher authorities who considered the supersession unjusti fied and who	 having powers to set aside orders of superses sion	 have set aside such orders. In such cases	 the circu lar provides	 the government servant concerned should be deemed to have been promoted to the higher post from the date from which he would have been promoted but for his wrongful supersession. There is no question in the present case of the respondent being promoted on the basis of any order passed by a higher authority. Nor indeed did any higher authority consider the so called supersession of the respondent as unjustified. While approving the revised seniority list in which the respondent occupied a much higher place than previously	 the Central Government did not set aside any order of the respondent 's supersession nor did it pass any order directing that the respondent be promoted to a higher post. We are clear that the circular of Febru ary 25	 1965	 on which judgment.of the High Court rests	 is not intended to govern questions of seniority and superses sion arising as a result of reorganisation of States. That circular	 by its language	 is designed to meet cases in which a government servant	 apart from the provisions of the States Reorganisation Act and apart from problems arising out of reorganisation of States	 was denied his rightful seniority but is later accorded a due and appropriate place in the seniority list. Paragraph 2 of the circular which speaks also of posts within the purview of the Public Serv ice Commission affords some indication that the circular is intended to apply only to cases of routine supersessions in the normal course of a service career. If the circular of February 25	 1965 were intended to apply to a case like the present	 it would have atleast referred to the circular of March 10	 1960 which specifical ly governs matters relating to fixation of seniority conse quent upon the reorganisation of States. That circular	 insofar as relevant	 reads thus: 591 "Fixation of Seniority and pay on promotion according to final gradation lists. GOVERNMENT OF BOMBAY Political and Services Department Circular No. SR INT 1059 VI Sachivalaya	 Bombay	 10th March	 1960 CIRCULAR OF GOVERNMENT Promotions made on and after the 1st November	 1956	 have been treated as provi sional pending absorption of the personnel and finalisation of gradation lists in accordance with the allocated Government Servants ' (Absorption	 Seniority	 Pay and Allowances) Rules 1957. They are also subject to review in the light of the changes that may be made in the gradation lists as a result of the decisions on the representations Submitted by the Government Servants concerned. Question has been raised as to how seniority and pay in the promotion post should be fixed in the case of a Government servant who in the light of the final gradation list	 is promoted later than the date on which he was due for promo tion. Government is pleased to direct that seniority and initial pay on promotion according to the final gradation list should be fixed as if the Government servant had been promoted on the date on which he would have been promoted had the gradation list been finalised on the 1st November 1956. The date on which he would have been promoted should be admitted on the basis of a certificate given by the appointing authority specifying the date. No arrears of pay should	 however	 be paid for the period prior to the date of actual promotion. " Under this circular	 the seniority and initial pay of the respondent has to be fixed as if he was promoted on the date on which he would have been promoted if the gradation list had been finalised on November 1	 1956. But no arrears of pay can be paid to him for the period prior to the date of actual promotion. The State Government relied upon this circular by their counter affidavit filed in the High Court but no challenge was made by the respondent to the vires or the validity of that circular even though he had his peti tion amended in order to ask for arrears of salary. On the assumption that the circular is within the powers of the State Government	 we have no doubt that the respondent 's case .must fail within that circular	 in which case he would not be entitled to the arrears of salary for the period prior to the date of his actual promotion. Mr. Gupte appearing on behalf of the respondent relies upon rule 21 of "The Allocated Government Servants ' (Absorption	 Seniority	 Pay and Allowances) Rules	 1957" and argues that since 592 under that rule the respondent is entitled to draw .his pay and allowances with effect from the date of his promotion to the higher post including the deemed date of promotion	 the Government of Maharashtra has no power	 in view of the proviso to section 115(7) of the States Reorganisation Act	 to alter his conditions o[ service to his prejudice. This argument is being advanced for the first time in this Court	 but	 apart from that	 we are unable to agree either that rule 21 has the effect contended for or that the circular issued by the State Government fails within the mischief of the proviso to. section 115(7). By rule 21	 the arrears of pay and allowances "which may become due to an allocated govern ment servant" on the fixation of his pay as on November 1	 1956 shall be payable only with effect from the date from which he became available for service in the State of Bombay or would have been so available but for the causes mentioned in rule 2(d). Rule 21 is not in the nature of an entitle ment. On the other hand	 it restricts the right of the allocated government servant to receive pay and allowances "only with effect from the date" from which he became avail able for service in the State of Bombay or would have been so available except for the causes mentioned in rule 2(d). The circular issued by the Government of Maharashtra on February 25	 1965 does not take away from the respondent the right	 if any	 which was available to him under rule 21. For these reasons we set aside the judgment of the High Court	 allow this appeal and direct that the respondent 's writ petition shall stand dismissed. In view of the order passed at the time when special leave was granted	 appel lant shall pay the costs of the appeal to the respondent. Appeal allowed.

Consequent to reorganisation of States	 the Maharash tra Government published seniority lists from time to time	 erroneously according to the respondent a lower place of seniority with the result that juniors got promoted and his promotion was unduly delayed. The respondent filed a writ petition asking for due recognition of his seniority	 and later amended his petition	 claiming arrears of pay and allowances retrospectively from the date on which he ought to have been promoted according to the final gradation list wherein he was placed correctly and which was approved by the Central Government. The writ petition was allowed by the High Court. Before this Court the respondent contended that under rule 21 of the Allocated Government Servants (Absorption	 Seniority	 Pay and Allowances) Rules	 1957	 he was entitled to draw his pay and allowances from the date of his promo tion including the deemed date of promotion. Allowing the appeal by Special Leave	 the Court	 HELD: (1) The Maharashtra Government circular No. SRV 1064 dt. 25.2.1965 does not have the effect of altering the respondent 's conditions of service to his prejudice since the said circular issued by the State Government does not fall within the mischief of proviso to section 115(7) of the States Reorganisation Act. [592 A] (2) The circular deals with cases where Government servants who were superseded for promotion to the higher post are later promoted on orders of higher authorities who considered the supersession unjustified and who having power to set aside orders of supersession have set aside such orders. [590 D] (3) The circular dt. 25.2.1965 is not intended to govern questions of seniority and supersession arising as a result of Reorganisation of States. That circular by its language is designed to meet cases in which a Government servant apart from the provisions of States Reorganisation Act and apart from the problems arising out of reorganisa tion of States was denied his rightful seniority but is later accorded a due and appropriate place in the seniority list. [590 F G] (4) The circular issued by the Government of Maharashtra on February 25	 1965 does not take away from the respondent the right	 if any	 which was available to him under rule 21. Rule 21 is not in the nature of an entitlement. On the other hand	 it restricts the right of the allocated Government servant to receive pay and allowances "only with effect from the date" from which he became available for service or would have been so available except for the causes mentioned in rule 2(d). [592 B D] 588 (5) The respondent 's case must fall within the Bombay Government Circular No. SR INT 1059 VI dt. 10.3.1960 in which case he would not be entitled to the arrears for salary for the period prior to the date of his actual ' promotion.
