Summarize the following court judgment. ivil Appeal Nos. 232 233 of 1978. From the Judgment and Order dated 19.7.1977 of the Patna High Court in C.W.J.C. No. 756 of 1977. Ashok Sen	 Shankar Ghosh	 Tapas Ray	 Ms. section Janani	 Ms. Minakshi	 Mrs. Urmila Kapoor	 D. Goverdhan	 Rakesh K. Khanna	 Salman Khurshid	 R.P. Singh	 D.D. Mishra	 Mrs. G.S. Mishra and D.P. Mukherjee for the appearing parties. The Judgment of the Court was delievered by RAY	 J. These two appeals were filed against the common judgment and order dated 29th July	 1978 made by the Division Bench of the High Court at Patna in C.W.J.C. No. 756 of 1977 whereby the High Court quashed the orders of the government contained in Annexures 8	 9 and 10 to the writ petition. The facts unfurled from the writ petition are as follows: The respondent Nos. 1 to 5 in these appeals (the petitioners in the writ petition) were directly appointed in the Bihar Engineering Service Class II as Assistant Engineers of the Irrrigation Department on the recommendation of Bihar Public Service Commission and were posted in River Valley Project in 1961. The respondent Nos. 6 to 23 in C.A. No. 232 of 1978 (who are appellants in C.A. No. 233 of 1978 and respondent Nos. 5 to 22 in the writ petition) were working at that time as overseers in the Bihar Subordinate Engineering Service (Irrigation Department). On 7th April	 1958 the the Governor took a decision under rule 2 of the Public Works Department Code that 25% of the posts in the Bihar Engineering Service	 Class II shall be filled up by promotion	 subject to availability of suitable hands. Thus	 out of the total vacancies in Bihar Engineering Service	 Class II	 75% of the vacant posts as determined by the Government will be filled up by direct recruitment and 25% of the vacant posts will be filled up by promotion subject to availability of suitable candidates. By notification dated 413 18th July	 1964/27th August	 1964	 respondent Nos. 6 to 13 in C.A. No. 232 of 1978 (appellant Nos. 1 to 8 in C.A. No. 233 of 1978 and respondent Nos. 5 to 12 in the writ petition) who were members of the Bihar Subordinate Engineering Service (Overseers) were promoted to the post of Assistant Engineer in Class II and by another notification dated 21st July	 1969	 respondent Nos. 14 to 23 in C.A. No. 232 of 1978 (appellant Nos. 9 to 18 in C.A. No. 233 of 1978 and respondent Nos. 13 to 22 in the writ petition) were also promoted to Bihar Engineering Service	 Class II as Assistant Engineers. On February 25	 1969	 a seniority list of Assistant Engineers was published by the Department wherein the names of the respondent Nos. 1 to 5 (the petitioners) were mentioned at Sl. Nos. 170	 199	 208	 211 and 226 and the names of the respondent Nos. 6 to 23 (respondent Nos. 5 to 22 in writ petition) were mentioned at Sl. 253	 254	 256 to 262	 687 to 695 and 701 respectively The respondent Nos. 6 to 23 were thus shown as juniors to the respondent Nos. 1 to 5 (the petitioners). The respondent Nos. 6 to 23 feeling aggrieved by the said seniority list made representations claiming seniority over respondent Nos. 1 to 5. On 3rd May	 1972 the State of Bihar constituted a Committee known as Ramanand Committee by a resolution to consider the inter se seniority of Civil Engineers including the Assistant Engineers. On April 19	 1973 the Ramanand Committee submitted a report making certain recommendations. It was alleged that a revised seniority list was prepared wherein the respondent Nos. 1 to 5 were shown juniors to the respondent Nos. 6 to 23. This	 of course	 has been denied in affidavit in counter filed on behalf of the Government (appellants in C.A. No. 232 of 1978	 respondent Nos. 6 to 9 in C.A. 233 OF 1978	 and respondent Nos. 1 to 4 in the writ petition). On 21st of July	 1975	 an order was made whereby the date of promotion of respondent Nos. 6 to 13 was changed from 21st July	 1962 to 27th February	 1961 thereby making the respondent Nos. 1 to 5 juniors to respondent Nos. 6 to 13. This order is contained in annexure 8 to the writ petition. In other words	 the respondent Nos. 6 to 13 were promoted retrospectively from the State against it but the State government instead of redressing their grievances made another order on January 20	 1976 (annexure 9 to the writ petition) re fixing the seniority of respondent Nos. 6 & 7 promoting them to the Bihar Engineering Service with effect from December 19	 1958. Again	 to the prejudice of the respondent Nos. 1 to 5	 an order was passed by the State Government by which the date of promotion of respondent Nos. 14 to 23 was pushed back to February 27	 1961 making them also senior to the respondent Nos. 1 to 5. This order is contained in annexure 10 to the writ petition. 414 The respondent Nos. 1 to 5	 therefore	 filed a writ petition in the High Court at Patna being Civil Writ Petition No. 756 of 1977 challenging the seniority conferred on the respondent Nos. 6 to 23 (respondent Nos. 5 to 22 in the writ petition) by annexures 8	 9 and 10 on the ground that these orders were wholly arbitrary illegal	 void and inoperative and ineffective and so prayed for appropriate writ for quashing those orders. A counter affidavit was filed on behalf of the State Government. In Para 3(iii) of the said affidavit	 it has been averred that till 1957	 25% of the vacancies in Bihar Engineering Service	 Class II	 were being filled up by promotion from the Bihar Subordinate Engineering Service (commonly known as `Overseers '). Subsequently	 in the year 1958	 it was decided that 25% of the cadre posts in the Bihar Engineering Service	 Class II Both permanent and temporary	 shall be reserved for being filled up through promotion from the members of the Bihar Subordinate Engineering Service. It has been further averred in para 3(iv) that all the posts of temporary Assistant Engineers to which the Overseers were entitled to be promoted on the basis of 25% reservation in the cadre were not filled up by promotion of Overseers	 only 3 overseers were given promotion with effect from 19.12.1958 vide order No. A/P1 409 64 1 14294 dated 18.7.64/27.8.64. In the said affidavit it has also been stated that on a careful examination of the matter it was found that on the basis of total number of posts of Assistant Engineers in the Department	 the Overseers were entitled to 60 posts on the basis of 25% reservation till 1958	 out of which they were already given 33 posts and 27 more posts of Assistant Engineers were still due to them and accordingly by an order dated 20th January	 1976 the 21 Overseers who had earlier been given promotion as temporary Assistant Engineers from later dates in 1960	 1961 and 1962 by the order dated 18.7.64/27.8.64. were given promotion	 with effect from 19.12.1958. Due to this correction	 respondent Nos. 6 and 7 and one Shri Mithileshwari Sahay (since retired) were promoted as temporary Assistant Engineers with effect from 19.12.1958 in partial modification of the Government order dated 18.7.64/27.8.64 and another order dated July 12	 1975. It has been further stated that as a result of this modification in the dates of promotion as Assistant Engineer who by the order dated 20th January	 1976 were allowed promotion as temporary Assistant Engineers with effect from 19.12.1958 as against promotions from later dated in 1960	 1961 and 1962 given to them by earlier Government Order dated 27.8.1964 and order dated 21.7.1969. It has also been stated that the respondent Nos. 6 and 7 were entitled to promotion in 1958 and respondent Nos. 8 to 23 to promotions in 415 1960 and 1961	 on the basis of the reservation of 25% of the cadre post in the Bihar engineering Service	 Class II	 for promotion of Overseers from the Bihar Subordinate Engineering Service. It has been further averred that as against 21 consequential vacancies	 the case of only 17 Overseers was modified accordingly in supersession of the earlier Government order dated 18.7.64/27.8.64 and respondent Nos. 8 to 13 were given promotion as temporary Assistant Engineer with effect from 27.2.1961	 from which date the promotion was due to them on the basis of the quota by a Government Order No. 10501 (annexure 8 to the writ petition) dated July 12	 1975 and No. 17328 dated November 8	 1975 respectively. It has also been stated that the seniority list that was prepared and published in 1969 was tentative. The High Court	 Patna held that no person can be promoted with retrospective effect from a date when he was not born in the cadre so as to adversely effect others. The respondent Nos. 1 to 5 were recruited to the post of Assistant Engineer	 Class II before the respondent Nos. 6 to 23 were promoted to the post of Assistant Engineer	 Class II in the Bihar Engineering Service	 Class II. The High Court	 therefore	 held that the orders contained in Annexure 8	 9 and 10 promoting the respondent Nos. 6 to 23 (respondent Nos. 5 to 22 in the writ petition) with retrospective effect are bad and so quashed those Government orders referred to in the said annexures. Against this judgment and order made by the High Court	 the instant appeals on special leave were filed. The sole question which falls for decision in these appeals is whether the inter se seniority between the petitioners respondent Nos. 1 to 5 who are direct recruits and the Overseers belonging to the Bihar Subordinate Engineering Service (Irrigation Department) who had been promoted retrospectively in their 25% quota for the year 1958 as revised by the Government orders mentioned in annexures 8	 9 and 10 to the writ petition	 is arbitrary	 illegal and inoperative as those orders purport to affect prejudicial the seniority of the petitioners respondent Nos. 1 to 5 in the service of Bihar Engineering Service	 Class II. It is not disputed that in 1958 under Rule 2 of the Public Works Department Code	 the Government of Bihar took a decision to the effect that 25% of the posts in the Bihar Engineering Service	 Class II shall be filled up by promotion	 subject to availability of suitable hands. It also appears from the counter affidavit filed on behalf of the Government that in 1958	 the the total number of posts to be filled up by promotion from the Overseers in the Bihar Subordinate Engineering Service 416 (Irrigation Department) to the post of Assistant Engineer	 in Bihar Engineering Service	 Class II was 60 out of which only 33 posts were filled up by promotion	 leaving 27 more posts of Assistant Engineers to be filled up by promotion from the Overseers in the Bihar Subordinate Engineering Service (Irrigation Department). It is also clear from the averments made in the said counter affidavit that the petitioners respondent Nos. 1 to 5 were appointed in Bihar Engineering Service	 Class II on the recommendation of the Bihar Public Service Commission in the year 1961 and the respondent Nos. 6 to 13 who had been working in the Bihar Subordinate Engineering Service (Irrigation Department) as Overseers and having independent charge of the sub division were promoted to the post of Assistant Engineer	 Class II by notification dated 18.7.64/27.8.64. The respondent Nos. 14 to 23 were also promoted by notification dated 21.7.1969. On the basis of these appointments and promotions in the post of Assistant Engineer in the Bihar Engineering Service	 Class II	 a seniority list was prepared and published in february	 1969 tentatively wherein the petitioners respondent Nos. 1 to 5 were shown as senior to respondent Nos. 6 to 23. However	 the Government by its order dated 21st July	 1962 changed the date of promotion of respondent Nos. 6 to 13 from 21.7.1962 to 27.21961 (Annexure 8 to the writ petition) thereby making the petitioners respondent Nos. 1 to 5 junior to respondent Nos. 6 to 13. On January 20	 1976	 the Government passed another order re fixing the seniority of respondent Nos. 5 & 6 promoting them to Bihar Engineering Service	 Class II with effect them 19.12.1958 (Annexure 9 to the writ petition). Again an order contained in Annexure 10 to the writ petition was passed by which the date of promotion of respondent Nos. 14 to 23 was pushed back to February 27	 1961	 thus making them senior to the petitioners respondent Nos. 1 to 5. The petitioners respondent Nos. 1 to 5 challenged these three Government orders mainly on the ground that these orders giving promotion to the respondent Nos. 6 to 23 from a date earlier to their date of promotion to the post of Assistant Engineer in Bihar Engineering Service	 Class II purport to affect prejudicially the rights of the petitioners respondent Nos. 1 to 5 in as much as they were appointed to the post of Assistant Engineer in the Bihar Engineering Service	 Class II earlier to the promotion to the said post of the respondent Nos. 6 to 23. It has also been submitted in this connection that he seniority has to be reckoned amongst the officials working as Assistant Engineers in the Bihar Engineering Service	 Class II from the date of their appointment on promotion to the said Service. The petitioners respondent Nos. 1 to 5 being appointed earlier directly in the quota of direct recruits than the promoted respondents who were promoted later cannot be given 417 seniority in service to the petitioners respondent Nos. 1 to 5 and it was contended that the impugned orders are wholly illegal and unwarranted and so the High Court has rightly quashed the said orders. It has been further urged in this connection that the State can promote its employees with retrospective effect provided such retrospective promotion does not affect the right and seniority already earned by others. The petitioners respondent Nos. 1 to 5 who were senior to the petitioners respondents Nos. 6 to 23 were made junior to them by the said Government orders as contained in Annexure 8	 9 and 10 to the writ petition. It has	 therefore	 been contended that the promotion to the respondent Nos. 6 to 23 was illegal and arbitrary as the same had prejudicially affected the petitioners respondent Nos. 1 to 5 in regard to their seniority. The High Court while rendering its judgment relied on the decision in the case of A.K. Subraman and Ors. vs Union of India and Ors. 	 specially on the observation made therein as under: "Once the Assistant Engineers are regularly appointed to officiate as Executive Engineers within their quota they will be entitled to consideration in their own rights as Class I Officers to further promotions. Their "birth marks" in their earlier service will be of no relevance once they are regularly officiating in the grade of Executive Engineer within their quota. " The High Court held that no person can be promoted with retrospective effect from a date when he was not born in the cadre so as to adversely affect others. It is the admitted position that the respondent Nos. 6 to 23 were working as Overseers in the Bihar Subordinate Engineering Service and were promoted to the post of Assistant Engineer in Bihar Engineering Service	 Class II much after the petitioners respondents Nos. 1 to 5 were directly recruited and appointed on the basis of the recommendation of the Bihar Service Commission	 to the post of Assistant Engineers in 1961 and as such they have been working in the grade of Assistant Engineers much before the respondent Nos. 6 to 23. Undoubtedly	 on the basis of the order of the Governor in 1958	 the posts of Assistant Engineers are to be filled up from two sources i.e. by direct recruitment as well as by promotion from Overseers working in the Bihar Subordinate Engineering Service and the ratio of the vacan 418 cies to be filled up has been fixed as 75% from the direct recruits and 25% from the promotees. It has been urged on behalf of the respondent Nos. 6 to 23 that in view of the quota rule the respondent Nos. 6 to 23 who were promoted in the quota set out for promotees in respect of the vacancies of 1958 shall be taken to be promoted in 1958 notwithstanding that they have been actually promoted long after 1958 and after the direct recruits i.e. respondent Nos. 1 to 5 were recruited directly to the post of Assistant Engineers. In other words even though the respondent Nos. 6 to 23 have been promoted after the date of recruitment of respondent Nos. 1 to 5 to the post of Assistant Engineer	 still then the promote respondent Nos. 6 to 23 should be deemed to be senior to the direct recruit respondent Nos. 1 to 5 as they were promoted in the vacancies for 1958 quota set up for promotees. In support of this submission the decision in V.B. Badami etc. vs State of Mysore and Ors.	 [1976] 1 SCR 815 as well as Gonal Bihimappa vs State of Kanataka	 [1987] Supp. SCC 207 were cited at the bar. In both these cases the promotees occupied the quota of direct recruits as direct recruits were not available to fill up the quota meant for them. It was held that direct recruits who were appointed within their quota subsequently were entitled to the vacancies within their quota which had not been filled up and they would become senior to the promotees The promotees would be pushed down to later years when their appointment could be regularised as a result of absorption in their lawful quota of those years. The promotees cannot claim any right to hold promotional posts unless the vacancies fall within their quota. These cases have no application in the instant case in as much as the direct recruits i.e. respondent Nos. 1 to 5 were recruited in their quota i.e. the quota meant for them. This being so	 the decision in these two cases has no application to the instant case. Moreover	 there is nothing to show that the respondent Nos. 6 to 23 who were promoted in 1962 and thereafter i.e. subsequent to the direct recruits i.e. respondent Nos. 1 to 5 could be deemed to be recruited in 1958 quota as there was nothing to show that these vacancies were carried forward. The Government 's orders as contained in annexures 8	 9 and 10 which purport to give promotion to the respondent Nos. 6 to 23 retrospectively are arbitrary	 illegal and inoperative in as much as these seriously affect the respondent Nos. 1 to 5. The respondent Nos. 6 to 23 were not in the cadre of Assistant Engineers even in officiating capacity at the time when the respondent Nos. 1 to 5 were directly recruited to the post of Assistant Engineer. As such	 the said promotee respondent Nos. 6 to 23 could not be under any circumstances	 given seniority over the directly recruited respondent Nos. 1 to 5. The 419 High Court has rightly quoted the observation made by this Court in the case of A.K. Subraman & Ors. (supra) as mentioned in the preceding paragraphs. It is pertinent to mention in this connection	 the observation of this Court in the case of D.K. Mitra and Ors. vs Union of India and Ors.	 [1985] Supp. SCC 243. In this case the petitioners were confirmed as Assistant Medical Officers in 1962 and 1963 and they were placed in the higher scale of Assistant Divisional Medical Officers to the Indian Railways with effect from January 1	 1973. Thereafter they were appointed as officiating Divisional Medical Officers in 1972	 1973 and 1974 and they had been continuing there uninterrupted. Respondent Nos. 4 to 64 were given substantive appointments as Divisional Medical Officers later on but they were confirmed earlier than the petitioners because of the zone wise confirmation given by the Railway Administration. It was held that the petitioners should be considered at par for the purpose of fixing seniority	 with those appointed to permanent posts in a substantive capacity. For the purpose of determining seniority among promotees	 the petitioners should be treated as having been appointed to permanent vacancies from the respective dates of their original appointment and the "entire period of officiating service performed by them should be taken into account as if that service was of the same character as that performed by the substantive holders of permanent posts. " In the instant case	 the promotee respondent Nos. 6 to 23 were not born in the cadre of Assistant Engineer in the Bihar Engineering Service	 Class II at the time when the respondent Nos. 1 to 5 were directly recruited to the post of Assistant Engineer and as such they cannot be given seniority in the service of Assistant Engineers over the respondent Nos. 1 to 5. It is well settled that no person can be promoted with retrospective effect from a date when he was not born in the cadre so as to adversely affect others. It is well settled by several decisions of this Court that amongst members of the same grade seniority is reckoned from the date of their initial entry into the service. In other words	 seniority inter se amongst the Assistant Engineers in Bihar Engineering Service	 Class II will be considered from the date of the length of service rendered as Assistant Engineers. This being the position in law the respondent Nos. 6 to 23 can not be made senior to the respondent Nos. 1 to 5 by the impugned Government orders as they entered into the said Service by promotion after the respondent Nos. 1 to 5 were directly recruited in the quota of 420 direct recruits. The judgment of the High Court quashing the impugned Government orders made in annexures	 8	 9 and 10 is unexceptionable. In the premises aforesaid	 we confirm the judgment and order rendered by the High Court. The appeals are	 therefore	 dismissed. In the facts and circumstances of the case	 there will be no order as to costs. R.P. Appeals dismissed.

Under Rule 2 of the Bihar Public Works Department Code	 the Governor of Bihar took a decision on 7.4.1958 providing that 25% of the posts of Assistant Engineers in the Bihar Engineering Service	 Class II (the Service) were to be filled by promotion	 subject to availability of suitable hands	 from Overseers in the Bihar Subordinate Engineering Service (Irrigation Department) and 75% of the posts were to be filled by direct recruitment to the Service. Respondents No. 1 to 5 in both these appeals were appointed as Assistant Engineers in the Service on the recommendation of the Bihar Public Service Commission in the year 1961; and the appellants (in Civil Appeal No. 233 of 1978(respondents No. 6 to 23 in Civil Appeal No. 232 of 1978)	 who had been working as Overseers in the Bihar Subordinate Engineering Service (Irrigation Department) were promoted to the posts of Assistant Engineers in the Service in 1962 and thereafter. However	 by orders dated 12.7.1975	 20.1.1976 and 9.4.1977	 the Government changed the date of promotion of the appellants to the dates prior to the appointment of respondents No. 1 to 5 in the Service	 making the former Senior to the letter. Respondents No. 1 to 5 filed writ petition before the High Court challenging the seniority conferred on the appellants from the retrospective date and contended that the orders giving promotions to the appellants from a date earlier to date of their promotion in the Service purported to affect prejudicially respondents No. 1 to 5 's right inasmuch as they were appointed to the Service earlier to the promotion of the appellants; and that the seniority had to be reckoned amongst the officials working as Assistant Engineers in the Service from the date of their appointment or promotion to the said Service. The appellants contended that they were entitled to be promoted retrospectively on the 411 basis of reservation of 25% of the Cadre posts in the Service till 1958. The High Court. holding that the orders promoting the appellants with retrospective effect were bad	 quashed the same and allowed the writ petition. Hence the present appeals. On consideration of the legality and validity of the orders of the Government giving promotions to the appellants from a date earlier to the date of their entry into the Service as Assistant Engineers	 and its effect on the inter se seniority amongst the appellants and respondents No. 1 to 5	 who were directly appointed as Assistant Enginers in the Service before the appellants entered in the said Service. Dismissing the appeals	 this Court	 HELD: 1. The Government Orders dated 12.7.1975	 20.1.1976 and 9.4.1977 which purported to give promotion to the appellants retrospectively were arbitrary	 illegal and inoperative inasmuch as these seriously affected rspondents No. 1 to 5. The appellants were not borne in the cadre of Assistant Engineers even in officiating capacity at time when rspondents No. 1 to 5 were directly recruited to the post of Assistant Egineer. As such	 the promotee appellants could not be under any circumstance given seniority over the directly recruited respondents No. 1 to 5. The judgment of the High Court in quashing the impugned Government Orders was	 therefore	 unexceptionable. [418F H; 420A] 2.1 No person can be promoted with retrospective effect from a date when he was not borne in the Cadre so as to adversely affect others; and amongst members of the same grade	 seniority is reckoned from the date of their initial entry into the service. [419F] 2.2 Seniority inter se amongst the Assistant Engineers in Bihar Engineering Service	 Class II would be considered from the date of the length of service rendered as Assistant Engineers. Therefore	 the appellants could not be made senior to respondents No. 1 to 5 by the impugned Government Orders as they entered into the said Service in 1962 and thereafter by promotion subsequent to respondent No. 1 to 5 who were directly recruited in the quota meant for them. There was nothing to show that the appellants could be deemed to be recruited in 1958 quota and that these vacancies were carried forward. [419G; 418E F] A.K. Subraman and Ors. vs Union of India and Ors.	 	 relied on. 412 V.B. Badami vs State of Mysore and Ors.
