Summarize the following court judgment. tition Nos. 4480 of 1980 and 2962 of 1981 (Under article 32 of the Constitution of India) S.N. Jha for the Petitioner in W.P. 4480/80. Girish Chandra for the Petitioner in W.P. 2962/81. M.M. Abdul Khadar and R.N. Poddar for the Respondent. The Judgment of the Court was delivered by CHANDRACHUD	 C. J. The petitioners	 Prem Prakash and Dal Chand Anand	 are members of a scheduled caste. By these writ petitions under article 32 of the Constitution	 they ask for a writ of mandamus directing the respondents to appoint them against 567 the vacancies reserved for members of Scheduled Castes and Scheduled Tribes in the Delhi Judicial Service. They also ask for a writ of prohibition to the effect that the respondents should not fill up the reserved vacancies for which they competed	 either by holding a fresh examination or by appointing candidates who had qualified in any previous examination. The Union of India	 the Administrator of the Union Territory of Delhi and the Registrar of the Delhi High Court are respondents 1	 2 and 3 to these petitions. On September 26	 1979	 the Registrar of the Delhi High Court published a newspaper advertisement that the Delhi High Court will hold an examination for recruitment of officers to the Delhi Judicial Service on January 11	 12 and 13	 1980 in the time scale pay of Rs. 650 1200. The advertisement stated that the total number of vacancies was 16	 out of which 2 were reserved for Scheduled Castes and 1 for Scheduled Tribes. In addition	 according to the advertisement	 there were 2 carry forward vacancies for members of Scheduled Tribes. In case of non availability of Scheduled Tribes candidates	 those vacancies were liable to be transferred as reserved vacancies for Scheduled Castes candidates. A competitive examination was held in pursuance of the said advertisement in accordance with the Delhi Judicial Service Rules	 1970 which were framed by the Lieutenant Governor of Delhi in consultation with the High Court of Delhi. Rules 18 and 28 read thus: "Rule 18 The Selection Committee shall prepare a list of candidates in order of merit. Such list will be forwarded to the Administrator for filling the vacancies then existing or any vacancy that may occur within a period of one year of the preparation of the list." "Rule 28 Appointments made to the Service by competitive examination shall be subject to order regarding special representation in the Service for Scheduled Castes and Scheduled Tribes issued by the Central Government from time to time. " The Brochure on 'Reservation for Scheduled Castes and Scheduled Tribes in Services '	 (5th ed.	 1978) issued by the Government of India	 Dept. of Personnel and Administrative Reforms	 Ministry of Home Affairs contains orders and instructions issued by 568 the Government of India from time to time on the question of reservation of vacancies for Scheduled Castes and Scheduled Tribes candidates. The relevant paragraphs of that Brochure read as follows: "2.1 Subject to Exemptions and Exclusions referred in Chapter 3	 the following reservations are in force in favour of SC and ST in filling vacancies in posts and services under the Govt. of India. (1) Direct recruitment on an all India basis: SC ST (a) By open competition(i.e.	 15% 71/2% through the UPSC or by means of open competi tive test held by any other authority)". "4.2 The actual number of vacancies to be reserved for SC and ST in any recruitment should be determined on the basis of the points in the roster and also taking into account the reservations brought forward from the previous year	 the total number of reservations not exceeding normally 50% of the total number of vacancies filled in that year. However	 the carry forward reserved vacancies would be available together with the current reserved vacancies for utilisation even where the total number of such reserved vacancies exceed 50% of the vacancies filled in that year provided	 the over all representation of SC/ST in the total strength of the concerned grade or cadre is found to be inadequate	 i.e.	 the total number of SC/ST candidates in that grade has not reached the prescribed percentage of reservation for SC/ST respectively	 in the grade	 as a whole". "9.2 Advertisement of reserved vacancies for posts filled by direct recruitment through examination: Where direct recruitment is made through examination	 for reserved as well as unreserved vacancies	 a single advertisement would be issued for such examination but the number of the vacancies reserved for SC and ST would 569 be specified clearly in it and in case the required number of SC or ST candidates are not available even by applying relaxed standards for the vacancy/vacancies reserved for them	 the remaining vacancy/vacancies should be filled by general candidate after dereservation of such vacancy/vacancies	 subject to the reservations being carried forward as required." "11.1 Carry over of reservations: If a sufficient number of reserved communities candidates fit for appointments against reserved vacancies are not forthcoming	 such vacancies can be dereserved after following prescribed procedure for dereservation as in Chapter 10 and thereafter they can be filled by candidates of other communities	 but the reservations shall be carried forward to subsequent three years of recruitment (except in the case of. . . . . ) where there will be no carry forward of unfilled reserved vacancies	 the total number of reservations not exceeding normally 50% of the total number of vacancies to be filled in that year. The surplus	 if any	 above 50% when the ceiling of 50% is applied	 shall be carried forward to the subsequent year of recruitment	 subject	 however	 to the condition that the particular vacancies carried forward do not become time barred due to their becoming more than three years old. However	 the carried forward reserved vacancies would be available together with the current reserved vacancies for utilisation even where the total number of such reserved vacancies exceeds 50% of the vacancies filled in that year provided	 the overall representation of SC & ST in the total strength of the concerned grade or cadre is found to be inadequate	 i.e.	 the total number of SC/ST candidates in that grade has not reached the prescribed percentage of reservation for SC/ST respectively	 in the grade	 as a whole". "Note (2): Any recruitment of SC/ST candidates will first be counted against the additional quota brought forward from the previous years in their chronological order. If SC/ST candidates are not available for all the vacancies	 the older	 carried forward vacancies should be filled first 570 and the comparatively later carried forward vacancies should be further carried forward". The petitioners appeared for the examination and passed it	 though by relaxation of the minimum standard prescribed for passing the examination. They were then asked to appear at the viva voce test conducted by the Selection Committee	 which they did. Since	 only seven open candidates and four Scheduled Caste candidates qualified in these tests	 the High Court prepared a merit list of 11 candidates as against 16 vacancies which were advertised. Dal Chand Anand	 who is petitioner in Writ Petition No. 2962 of 1981	 was 10th in the merit list while Prem Prakash	 who is petitioner in Writ Petition No. 4480 of 1980	 was 11th in that list. They were respectively 3rd and 4th in the merit list amongst the 4 Scheduled Caste Candidates. Since they did not figure in the final list of candidates selected by the Administrator	 they have filed these petitions to challenge their exclusion and non appointment. A counter affidavit has been filed on behalf of respondent 3 by Shri Ramesh Sharma	 Assistant Registrar of the Delhi High Court. The position taken up by the Delhi High Court in that affidavit may be summarized thus: The Delhi Judicial Service was constituted on August 2	 1971. Rule 28	 which provides for special representation for members of the Scheduled Castes and Scheduled Tribes	 is applicable to the recruitment made through a competitive examination only and	 therefore	 no reservations were made either in favour of Scheduled Castes or Scheduled Tribes at the stage of the initial recruitment to the Service	 which was not by competitive examination. Representations were	 however	 made to the Ministry of Law and Justice as a result of which	 the Delhi Administration was instructed administratively to take suitable steps	 if necessary by amendment of the recruitment Rules	 so as to provide for reservations for the Scheduled Castes and Scheduled Tribes at the initial constitution of the Service also. In a meeting of officers of the Ministry of Law and Justice	 the Delhi Administration and the High Court	 which was held in November	 1971	 it was decided that 15 per cent of the vacancies filled in the Delhi Judicial Service should be reserved for Scheduled Castes and 71/2 per cent for Scheduled Tribes and that	 vacancies which ought to have been reserved for these categories at the initial recruitment should be carried forward to the following year. The statutory rules were not amended in pursuance of this decision	 which is but one instance of the wide chasm which exists between the lip service paid to the need for 571 reservations for backward classes and the actual performance in terms of social awareness. The counter affidavit says that the 6th competitive examination at which the petitioners appeared was held in 1980. 16 Vacancies were notified	 out of which 11 were for open candidates	 2 for Scheduled Castes and 3 for Scheduled Tribes. Two out of the three vacancies reserved for Scheduled Tribes were interchangeable in the sense that	 if candidates from Scheduled Tribes were not available	 those vacancies could be added to the quota reserved for Scheduled Castes. The counter affidavit of the High Court contains a candid admission in paragraph 17 that when	 in 1980 and 1981	 the High Court examined the question of reservation of vacancies for Scheduled Castes and Scheduled Tribes right from the stage of initial constitution of the Service in 1971	 it found that "there was apparently a violation of statutory Rules and the vacancies had been wrongly calculated by the Registry of the High Court". The High Court rectified its error by recommending the appointment of 2 Scheduled Caste candidates for the 1980 vacancies from amongst the candidates who had qualified in the 1979 competitive examination but who	 on account of a mistaken calculation	 were not appointed to the reserved seats. We are happy to find that consistency in adhering to errors is not the hobgoblin of our High Courts. The factual position which emerges out of the averments in the Writ Petitions and the counter affidavit filed on behalf of the High Court is that though 16 vacancies were advertised	 only 11 vacancies could possibly be filled up. The reason is that only 11 candidates passed the competitive examination. Seven out of these 11 had competed for open seats while four had competed for seats reserved for the Scheduled Castes If the four reserved seats could be filled up by the appointment thereto of candidates who appeared in the 1980 examination	 there would be no difficulty in accommodating the petitioners because. they are 10th and 11th in the merit list of 1980. Normally	 vacancies which are intended to be filled by holding an examination in any particular year	 are filled from amongst candidates who had appeared for that examination. The situation in this case is	 however	 complicated by the fact that two Scheduled Caste candidates	 Ajaib Singh and Ram Swarup	 who had appeared for the competitive examination in the previous year	 that is in 1979	 were wrongly denied appointments. They had 572 passed the examination and reserved vacancies were available in which they could and ought to have been appointed. Ajaib Singh filed a Writ Petition in this Court (No 312 of 1980) which was allowed by us by an order dated September 2	 1981. That order reads thus : "We are informed that the Delhi High Court has decided in a full Court meeting to recommend the names of the petitioner Ajaib Singh and another candidate Ram Swarup	 for appointment to the post for which they had applied	 namely	 the post of the Sub Judge. The duration of the panel which was prepared for the year 1979 expired on August 16	 1980	 That makes it necessary to direct that the names of the petitioner Ajaib Singh and the other candidate Ram Swarup should be included in the panel for the year 1979 and the appointment of these persons be made by the Delhi Administration despite the expiration of the period of that panel." The High Court took the particular decision in a full Court meeting because it found	 and rightly so	 that Ajaib Singh and Ram Swarup were denied appointments due to an error on the part of its Registry in calculating the number of reserved seats which were available in the year 1979. The error committed by the High Court Registry is to be regretted and we hope that errors which betray lack of care in matters which make or mar a person will not be repeated. But the question which arose for the administrative consideration of the High Court was whether the injustice done to the two candidates should be perpetuated on the specious plea that	 after all	 the High Court had taken a certain decision and that decision must be respected	 whether it is administrative or judicial. We are glad to find that the High Court did not stand on a false sense of prestige and rectified the injustice done to the two candidates by correcting an error for which they were not to blame. On our part	 we considered it unfair that they should be denied appointments and be made to suffer injustice for the error of the Registry in applying the reservation formula. The counter affidavit filed on behalf of the High Court shows that the first two seats	 from out of the four seats which were available to the Scheduled Caste candidates in the year 1980	 have been allotted to Ajaib Singh and Ram Swarup	 subject to the result of these writ petitions. It is ironical that the rectification of injustice done to some 573 two persons should result in injustice to two others. But	 that is exactly what has happened in this case	 as if to illustrate that one man 's food is another man 's poison. The contention of the High Court is that though the petitioners were in the merit list of 11 persons for the year 1980	 they could not be appointed as Sub Judges because	 Ajaib Singh and Ram Swarup who were wrongly excluded from the reserved appointments of 1979 had to be accommodated in the merit list of 1980 and	 after adjusting them against the reserved vacancies of 1980	 no reserved vacancies were left for the candidates who were placed in the merit list of 1980. When	 in furtherance of the decision taken by the Full Court meeting of the High Court	 we directed on September 2	 1981 that the two candidates of 1979 must be included in the 1979 panel and appointed as Sub Judges despite the expiry of the duration of that panel	 little did we realise	 and it was not so stated before us	 that the appointment of those two candidates of 1979 will mean the ouster of these two candidates of 1980. Such a strange result is to be avoided	 if not at all costs	 at least within the framework of the Rules and the administrative instructions governing this matter. Justice to one group at the expense of injustice to another is perpetuation of injustice in some form or the other. The counter affidavit of the Assistant Registrar explains the arithmetic of the High Court decision as to why the petitioners were excluded from the selections of 1980. History has the habit of repeating itself and	 with great respect	 the High Court has once again fallen into an error while deciding whether	 after accommodating Ajaib Singh and Ram Swarup in the 1980 selection	 reserved vacancies were still available in which the petitioners could be appointed. The explanation of the High Court may best be stated in the words of its Assistant Registrar. He says in paragraph 21 of his counter affidavit : "It is submitted that in view of the fact that only 11 candidates qualified in the examination of which 7 were general candidates. Therefore	 in accordance with the advice contained in the D. O. letter No. 36034/19/79 Est (SCT) dated August 13	 1979 of the Department of Personnel and Administrative Reforms	 as against 7 general candidates only one Scheduled Caste candidate could be taken and accordingly	 7 general candidates and 1 Scheduled Caste candidate and in addition 2 more Scheduled Caste candidates as against 2 carried forward exchangeable vacancies 574 of Scheduled Tribes were recommended for appointment to the Delhi Judicial Service. " The counter affidavit says that the name of Dal Chand Anand	 who is petitioner in Writ Petition No. 2962 of 1981	 was recommended for appointment since he was 3rd amongst the four Scheduled Caste candidates but that the	 said recommendation was made under an erroneous belief that a vacancy was available in which he could be appointed. When the mistake was realised by the High Court	 his name was dropped. In so far as the other petitioner	 Prem Prakash	 is concerned	 the explanation of the Assistant Registrar is that no vacancy was available at all in which he could be appointed since	 he was 4th in the list of Scheduled Caste candidates. The error from which the calculation of the High Court suffers is that the number of vacancies available for the Scheduled Caste candidates was fixed by it according to the number of candidates who qualified for the general seats. The counter affidavit states expressly that the availability of vacancies for candidates of the reserved category was determined on the basis that only 7 candidates had qualified for the general seats. This	 according to us	 is neither justified by the Rules and administrative instructions nor indeed does such a method of fixation of reserved vacancies disclose any acceptable basis. 16 Vacancies were advertised in the first instance out of which	 11 were for general candidates and 5 for reserved categories. It may be assumed that the Administration is not bound to fill all the vacancies which are advertised and indeed	 if the number of candidates who qualify in the competitive examination is less than the number of vacancies which are advertised	 it is obvious that the vacancies which can be filled will be less than the vacancies which are advertised. But the availability of vacancies for the reserved categories cannot be made to depend upon the accidental circumstance of how many candidates have qualified for general seats. In the first place	 that would be contrary to the instructions contained in paragraphs 4.2 and 9.2 of the Brochure of 1978. Secondly	 such a method will lead to the absurd and undesirable consequence that no candidate of the reserved category will be appointed at all	 if only one or two candidates from the general category qualify in the examination. The correct approach is to fix the number of vacancies available for the reserved candidates on the basis of the total number of vacancies which are intended to be filled at any particular point of time. According to paragraph 575 2.1 of the Brochure	 15% of the total vacancies are required to be reserved for the Scheduled Caste candidates and 7 1/2% for the Scheduled Tribe candidates. Therefore	 the High Court could not have fixed the number of vacancies available to the reserved candidates on the basis that only 7 persons had qualified for the general seats. If a decision was taken to fill 10 or 11 posts only	 the number of reserved vacancies should have been fixed upon that basis and not on the basis that only 7 candidates had qualified for the general seats. The High Court should have corrected its error in these two cases with the same alacrity with which it corrected its error in the case of the two Scheduled Caste candidates who had qualified in 1979. There is an additional reason in support of the view which we are disposed to take. On February 8	 1982 the Ministry of Home Affairs	 Department of Personnel and Administrative reforms	 issued a notification to the following effect : "Sub: Validity period of lists of selected candidates prepared on the basis of direct recruitment/Department competitive Examination. The undersigned is directed to say that reference are being received from time to time from Ministries/Deptts. enquiring as to what should be the validity period of a list of selected candidates prepared on the basis of direct recruitment or Departmental competitive Examination Normally	 in the case of direct recruitment a list of selected candidates is prepared to the extent of the number of vacancies (other persons found suitable being put on a reserve list	 in case some of the persons on the list of selected candidates do not become available for appointment). Similarly	 in the case of Departmental competitive Examinations the list of selected candidates has to be based on the number of vacancies on the date of declaration of results	 as the examination is competitive and selection is based on merit. A problem may arise when there is a fluctuation in the vacancies after the list of selected candidates is announced. The matter has been carefully considered. Normally	 recruitment whether from the open market or through a 576 Departmental competitive Examination should take place only when there are no candidates available from an earlier list of selected candidates. However	 there is a likelihood of vacancies arising in future: in case	 names of selected candidates are already available	 there should either be no further recruitment till the available selected candidates are absorbed or the declared vacancies for the next examination should take into account the number of persons already in the list of selected candidates awaiting appointment. Thus	 there would be no limit on the period of validity of the list of selected candidates prepared to the extent of declared vacancies	 either by the method of direct recruitment or through a Departmental Competitive Examination. Once a person is declared successful according to the merit list of selected candidates	 which is based on the declared number of vacancies	 the appointing authority has the responsibility to appoint him even if the number of the vacancies undergoes a change	 after his name has been included in the list of selected candidates. Thus	 where selected candidates are awaiting appointment	 recruitment should either be postponed till all the selected candidates are accommodated or alternatively intake for the next recruitment reduced by the number of candidates already awaiting appointment and the candidates awaiting appointment from a fresh list from the subsequent recruitment or examination. Ministry of Finance	 etc. are requested to bring the above instructions to the notice of all the appointing authorities under them for information and guidance. Sd/ (J. K. Sarma) Director. " It is clear from this notification that if selected candidates are available from the previous list	 there should either be no further recruitment until those candidates are absorbed or	 in the alternative	 vacancies which are declared for the subsequent years should take into account the number of persons who are already in the list of selected candidates who are still awaiting appointment. The notification further shows that there should be no limit on the period of validity of the list of selected candidates prepared to the extent 577 of declared vacancies. Once a person is declared successful according to the merit list of selected candidates	 the appointing authority as the responsibility to appoint him	 even if the number of vacancies undergoes a change after his name is included in the list of selected candidates. We must record our dissatisfaction at the fact that the Rules of the Delhi Judicial Service have not been amended so as to bring them in conformity with the administrative instructions and notifications which have been issued by the Ministry of Home Affairs	 Department of Personnel and Administrative Reforms	 from time to time. The situation is virtually chaotic for which	 we must clarify	 the High Court of Delhi cannot be blamed. It is surprising that though 13 years have gone by since the Delhi Judicial Service was established	 no attention whatsoever has been paid to a matter which concerns the future of a large number of young men and women who aspire for posts in the Judiciary. The instant case and the cases of Ajaib Singh and Ram Swarup show that the worst sufferers of this inaction are members of the Scheduled Castes and Scheduled Tribes. Sooner the Rules are amended	 easier will it be for the High Court to administer and superintend the affairs of the subordinate Judiciary with the object of achieving the ideals enshrined in Articles 16 (4)	 38 and 46 of the Constitution. Though the Rules ought to be amended	 that does not mean that administrative instructions can be ignored by the High Court until that is done. The Assistant Registrar says in paragraph 9 of his counter affidavit that "administrative instructions cannot be allowed to prevail over the statutory rules. " That would be correct provided that the administrative instructions are contrary to the statutory rules. In this case	 Rule 28 itself says that "Appointments made to the service by competitive examination shall be subject to order regarding special representation in the service for Scheduled Castes and Scheduled Tribes issued by the Central Government from time to time. " Therefore	 far from their being any inconsistency between the statutory rules and the administrative instructions it is clear that the two have to be read together. These writ petitions must therefore succeed. Our reasons for allowing the petitions may be summed up thus: In the first place. 	 in the process of remedying injustice which was done to the two scheduled caste candidates of 1979	 no injustice can be caused to the petitioners who had qualified for the reserved seats in the exami 578 nation held in 1980. Secondly	 the quota of seats available for reserved candidates cannot be made to depend on the fortuitous circumstance as to how many candidates have qualified for the general seats. The reserved quota must be fixed on the basis of the total number of vacancies which are to be filled at a given point of time. Thirdly	 the notification of 1982 is good authority for adjusting the petitioners against the reserved vacancies for the year 1980. The statutory rules and administrative instructions have to be read together by reason of Rule 28. We accordingly direct that the High Court and the Delhi Administration will take expeditious steps for notifying the appointments of the petitioners	 Dal Chand Anand and Prem Prakash	 to the Delhi Judicial Service. For purposes of seniority the former will rank higher than the latter because that was their orders of seniority in the original merit list of 1980. Since they have not actually worked as Sub Judges during the intervening period	 they will not be entitled to any remuneration for that period. They will however rank for seniority in the Delhi Judicial Service on the footing that they were appointed when they ought to have been appointed	 that is to say	 when the other candidates were appointed on the basis of the result of the 1980 examination. In all other respects	 including probation	 their appointment will be subject to the provisions of the relevant rules and regulations. In the result	 the writ petitions are allowed to the extent indicated above. Respondents 1 and 2 will pay to the petitioners the costs of these petitions. M.L.A. Petitions allowed.

Rule 18 of the Delhi Judicial Service Rules	 1970 (for short	 the Rules) says that the Selection Committee shall prepare a list of candidates in order of merit and forward it to the Administrator for filling the vacancies then existing or any vacancy that may occur within a period of one year of the preparation of the list. Rule 28 of the Rules lays down that appointments made to the Service by competitive examination shall be subject to order regarding special representation in the Service for Scheduled Castes and Scheduled Tribes issued by the Central Government from time to time. Paragraph 2.1 of the Brochure on "Reservation for Scheduled Castes and Scheduled Tribes in Services" issued by the Central Government requires that 15 per cent of the total vacancies are to be reserved for Scheduled Caste candidates and 71/2 for Scheduled Tribe candidates. Paragraph 4.2 of the Brochure prescribes that the actual number of vacancies to be reserved for Scheduled Castes and Scheduled Tribes in any recruitment should be determined on the basis of points in the roster and also taking into account the reservations brought forward from the previous year. On 8th February	 1982	 the Government of India issued a Notification declaring that there would be no limit on the period of validity of the list of selected candidates prepared to the extent of declared vacancies either by the method of direct recruitment or through a departmental competitive examination and that once a person is declared successful according to the merit list of selected candidates which is based on the declared number of vacancies	 the appointing authority has the responsibility to appoint him even if the number of vacancies undergoes a change after his name has been included in the list of selected candidates. 565 In 1980	 Respondent No. 3	 High Court of Delhi notified 16 vacancies of Sub Judges for being filled through competitive examination in the Delhi Judicial Service 11 vacancies were for open candidates	 2 for Scheduled Castes and 3 for Scheduled Tribes which included two carried forward vacancies also. The carried forward vacancies were interchangeable in the sense that if candidates from Scheduled Tribes were not available	 the vacancies could be added to the quota reserved for Scheduled Castes. The petitioners	 Dal Chand Anand and Prem Prakash	 who were members of Scheduled Caste secured 10th and 11th position respectively in the merit list of 11 candidates who qualified the examination and viva voce test held in pursuance of the above notification. They were Serial No. 3 Scheduled Caste candidates. Since the petitioners did not figure in the final list of candidates selected by the Administrator	 Respondent No. 2	 they filed present writ petitions under article 32 of the Constitution to challenge their exclusion and non appointment. Respondent No. 3 contended (1) that the petitioners were excluded from the selections of 1980	 on account of the fact that only 11 candidates qualified in the examination of which 7 were general candidates and therefore as against 7 general candidates only 1 Schedule Caste candidate could be appointed; and (ii) That though the petitioners were in the merit list of 11 persons for the year 1980	 they could not be appointed as Sub Judges because two Scheduled Caste candidates who were wrongly excluded from the reserved appointments of 1979 had to be accommodated in the merit list of 1980 and after adjusting them against the reserved vacancies of 1980	 no reserved vacancies were left for the petitioners. Allowing the Writ Petitions	 ^ HELD: (1) The error from which the calculation of the High Court suffers is that the number of vacancies available for the Scheduled Caste candidates was fixed by it according to the number of candidates who qualified for the general seats. This is neither justified by the Rules and administrative instructions nor indeed does such a method of fixation of reserved vacancies disclose any acceptable basis. The quota of seats available for reserved candidates cannot be made to depend on the fortuitous circumstance as to how many candidates have qualified for the general seats	 since that would be contrary to the instructions contained in paragraph 4.2 and 9.2 of the Brochure of 1978 and such a method will also lead to the absurd and undesirable consequence that no candidate of the reserved category will be appointed at all if only one or two candidates from the general category qualify in the examination. The correct approach is to fix the number of vacancies available for the reserved candidates on the basis of the total number of vacancies which are intended to be filled at any particular point of time. Therefore	 the High Court could not have fixed the number of vacancies available to the reserved candidates on the basis that only seven persons had qualified for general seats. If a decision was taken to fill 10 or 11 posts only	 the number of reserved vacancies should have been fixed upon that basis and not on the basis that only 7 candidates had qualified for the general seats. [574D E	 G H	 575A B] 566 (2) In the process of remedying injustice which was done to the 2 Scheduled Caste candidates of 1979	 no injustice can be caused to the petitioners who had qualified for the reserved seats in the examination held in 1980. Such a strange result is to be avoided if not at all costs	 at least within the framework of the Rules and the administrative instructions governing the matter. Justice to one group at the expense of injustice to another is perpetuation of injustice in some form or the other. [577H	 57 D] (3) The statutory rules and administrative instructions have to be read together unless they are contrary to each other. In the instant case	 since there is no in consistency between the statutory rules and the administrative instructions	 it is clear that the two have to be read together by reason of Rule 28. Though the Rules of the Delhi Judicial Service have not been amended so as to bring them inconformity with the administrative instructions and notifications which have been issued by the Ministry of Home Affairs	 Department of Personnel and Administrative Reforms	 from time to time	 that does not mean that administrative instructions can be ignored by the High Court until that is done. Therefore	 the Notification of 1982 is good authority for adjusting the petitioners against the reserved vacancies for the year 1980	 since it is clear from the Notification (i) that if selected candidates are available from the previous list	 there should either be no further recruitment until those candidates are absorbed or	 in the alternative	 vacancies which are declared for the subsequent years should take into account the number of persons who are already in the list of selected candidates who are still awaiting appointment and (ii) that there should be no limit on the period of validity of the list of selected candidates prepared to the extent of declared vacancies and once a person is declared successful according to the merit list of selected candidates	 the appointing authority has the responsibility to appoint him	 even if the number of vacancies undergoes a change after his name is included in the list of selected candidates.
