Summarize the following court judgment. y Application No. 1 of 1992. IN Writ Petition No. 1165 of 1986. (Under Article 32 of the Constitution of India). M.C. Bhandare	 P.P. Rao	 N.N. Goswamy	 C.K Sucharita	 Ms. Shashi Kiran	 Ms. Manjula Gupta	 R. Shashi Prabhu	 V.K. Verma and Raj Kumar Gupta for P.C. Kapur for the appearing parties. The Judgment of the Court was delivered by SAWANT	 J. The petitioner applicants are some of the Medical Officers who were recruited by the Railways on 	id hoc basis as Assistant Divisional Medical Officers between 1968 and 1st October	 1984. They were appointed as such ad hoc employees by way of a stop gap arrangement pending the regular recruitment to the said posts through the Union Public Service Commission [UPSC ' for short]	 according to the rules. It appears that although from time to time the UPSC recruited candidates on regular basis	 there remained some vacancies unfilled	 either because the doctors recruited were less in number than the number of vacancies since suitable candidates were not available or some of those who were selected did not join the service or between the date of advertisement by the UPSC and that of the empanelling	 some more vacancies occurred. Whatever the reasons	 the fact was that even after the UPSC undertook the exercise of recruiting the doctors from time to time	 some vacancies always remained unfilled. The result was that every time the petitioner applicants and others like them were continued on ad hoc basis as a stop gap arrangement till the next recruitment by the UPSC. It may be mentioned in this connection that the ad hoc appointees were always at liberty to appear before the UPSC for their regular recruitment. Some of them in fact did so appear and were selected; others like the petitioner applicants either failed to be selected or did not care to appear. The fact	 however	 remains that the petitioner applicants and others like them continued to serve on ad hoc 4 basis since 1968. Hence they filed writ petitions in this Court for their regularisation in service. By an order dated 24th September	 1987 passed in the case of Dr. A.K Jain & Ors. vs Union of India & Ors. 	 [1987] Supp. SCC 497 at 500 this court directed as follows: "(1) The services of all doctors appointed either as Assistant Medical Officers or as Assistant Divisional Medical Officers on ad hoc basis up to October 1	 1984 shall be regularised in consultation with the Union Public Service Commission on the evaluation of their work and conduct on the basis of their confidential reports in respect of a period subsequent to October 1	 1982. Such evaluation shall be done by the Union Public Service Commission. The doctors so regularised shall be appointed as Assistant Divisional Medical Officers with effect from the date from which they have been continuously working as Assistant Medical Officer/Assistant Divisional Medical Officer. The Railway shall be at liberty to terminat e the services of those who are not so regularised. If the services of any of the petitioners appointed prior to October 1	 1984 have been terminated except on resignation or on disciplinary grounds	 he shall be also considered for regularisation and if found fit his services shall be regularised as if there was not break in the continuity of service but without any back wages. (2) The petitions of the Assistant Medical Officers/Assistant Divisional Medical Officers appointed subsequent to October 1	 1984 are dismissed. But we however direct that the Assistant Divisional Medical Officers who may have been now selected by the Union Public Service Commission shall first be posted to the vacant posts available wherever they may be. If all those selected by the UPSC cannot be accommodated against the available vacant posts they may be posted to the posts now held by the doctors appointed on ad hoc basis subsequent to October 1	 1984 and on such posting the doctor holding the post on ad hoc basis shall vacate the same. While making such postings the principle of 'last come	 first go ' shall be 5 observed by the Railways on zonal basis. If any doctor who is displaced pursuant to the above direction is willing to serve in any other. zone where there is a vacancy he may be accommodated on ad hoc basis in such vacancy. (3) All Assistant Medical Officers/Assistant Divisional Medical Officers working on ad hoc basis shall be paid the same Wary and allowances as Assistant Divisional Medical Officers on the revised scale with effect from January 1	 1986. The arrears shall be paid within four months. (4) No ad hoc Assistant Medical Officer/Assistant Divisional Medical Officer who may be working in the Railways shall be replaced by any newly appointed AMO/ADMO on ad hoc basis. Whenever there is need for the appointment of any AMO/ADMOs on ad hoc basis in any zone the existing ad hoc AMO/ADMOs who are likely to be replaced by regularly appointed candidates shall be given preference. (5) If the ad hoc doctors appointed after October 1	 1984 apply for selection by the Union Public Service Commission the Union of India and the Railways Department shall grant relaxation in age	 to the extent of the period of service rendered by them as ad hoc doctors in the Railways. All the Writ Petitions are disposed of in the above terms. " It appears that since they experienced difficulty in adjusting the seniority of the petitioner applicants the Union of India moved an application before this Court and this court on 1st November	 1988 made the following order in that application: "We have heard learned counsel for the Union of India (the applicant in this Civil Miscellaneous Petition) and the learned counsel for the petitioners in the Writ Petition. In the circumstances of the case we feel that the Union 6 Government should be directed to implement the order passed by us in the writ petition Nos. 522	 875	 180 & 200 of 1987 and connected cases on 24th September	 1987 in full except to the extent of fixing the inter se seniority between the petitioners in the Writ Petition and the direct recruits. We accordingly make an order in this case. The question of seniority	 however	 is left to be decided by the Government in the light of the decision to be rendered by this Court in the cases which are pending before the Constitution Bench involving similar questions. If any person is aggrieved by the decision of the Government on the question of seniority he is at liberty to question it in an appropriate forum. The order passed by us in the Writ Petition subject to the above modification shall be complied with by the Union Government within two months without failure. The Civil Miscellaneous Petition is disposed of accordingly. " The present application has been moved in Writ Petition No. 1165 of 1986 which has been disposed of on 24th September	 1987 along with other writ petitions in which also the aforesaid order of 1st November	 1988 was made by this Court. Thus we are concerned in this application with those Assistant. Divisional Medical Officers who were appointed between 1968 and 1st October	 1984 and who have been regularised by the aforesaid two orders but whose seniority remains to be fixed. After the order of 1st November	 1988	 the Constitution Bench of this Court delivered its judgment in Direct Recruit Class II Engineering Officers ' Association & Ors. vs State of Maharashtra & Ors. 	 ; pending ' which decision the fixation of seniority of the petitioner applicants was kept pending. In that case the Constitution Bench has laid down certain guidelines for fixing the seniority. Two of them	 viz.	 (A) & (B)	 which are relevant for our purpose are as follows: "(A) Once an incumbent is appointed to a post according to rule	 his seniority has to be counted from the date of 7 his appointment and not according to the date of his confirmation. The corollary of the above rule is that where the initial appointment is only ad hoc and not according to rules and made as a stop gap arrangement	 the officiation in such post cannot be taken into account for considering the seniority. (B)If the initial appointment is not made by following the procedure laid down by the rules but the appointee continues in the post uninterruptedly till the regularisation of his service in accordance with the rules	 the period of officiating service will be counted. " Before we discuss as to which of the above two guidelines would be applicable in this case	 it is necessary to state the relevant facts relating to the applicants ' appointment. Firstly	 it is an admitted fact that the UPSC introduced the Combined Medical Services Examination for the first time in the year 1977. Prior to 1977	 the method of recruitment was otherwise than by examination. As stated earlier	 some of the petitioner applicants were recruited between 1968 and 1977. Secondly	 the petitioner applicants were given three chances for their selection through the UPSC but they did not avail of them. Some of those who were appointed with them	 however	 had availed of the chances and have been appointed as regular direct recruits and they have been given their seniority from the date they were regularly appointed through the UPSC. Thirdly	 it appears that although in 1977 the written examination was introduced	 on account of exigencies	 the UPSC held two special selections in the years 1982 and 1985 based on interviews only and by relaxing the age limit. In these two special selections respectively 100 and 67 ad hoc doctors like the petitioner applicants were selected and absorbed in the regular cadre. They have also been given their seniority from the date they were so absorbed regularly. The petitioner applicants either failed to appear in these examinations also or after appearing in the same	 had failed Thus	 while fixing the seniority of the petitioner applicants we have to keep in mind that there are three classes of Assistant Divisional Medical Officers (i) the outsiders who have been directly recruited through the UPSC either on the basis of the written examination or the interview; (ii) 8 those who were ad hoc appointees like the applicants but who came to be regularly recruited through the UPSC by appearing in the written examination or in the interview; and (iii) the present petitioner applicants who either did not appear in any written examination/interview or had failed to get through them but who have been regularised in service because of the orders of this Court dated 24th September	 1987 and 1st November	 1988. Since the petitioner applicants are admittedly not regularly appointed through the UPSC according to the rules but have been directed to be regularised by following the procedure laid down by this Court it is obvious that they are not appointed to their posts according to the rules. Under no circumstances	 therefore	 they fall within the scope of guideline (A) laid down in Direct Recruit Class II Engineering Officers Association 's case (supra). In fact	 they do not fall under guideline (B) given therein either	 since their regularisation is not in accordance with the rules but as a consequence of special procedure laid down by this Court. The expression "in accordance with the rules ' or "according to rules" used in the said guidelines (A) and (B) means the rules of recruitment and not the special procedure laid down by this Court. The petitioner applicants thus fall in an altogether different category not covered under any of the guidelines given in Direct Recruit Class II Engineering Officers ' Association 's case (supra). We have	 therefore	 to evolve a procedure for fixing their seniority. That procedure cannot be in violation of the guidelines laid down in Direct Recruit Class II Engineering Officers Association 's case (supra). Secondly	 the seniority given to the petitioner applicants will have to be below the seniority of the outsiders directly recruited through the UPSC as well as below that of the directly recruited erstwhile ad hoc Medical Officers This is not and cannot be disputed on behalf of the petitioner applicants. This matter was heard earlier on 14th September	 1992 and was reserved for judgment. At that time	 neither the in service direct recruits nor the outsider direct recruits were made parties to the application. They made separate applications	 being I.A. Nos. 2 and 3 respectively for im pleadment/intervention and requested that they be heard in the matter before judgment is pronounced. Hence	 this matter was set down for a fresh hearing and all the parties were heard on 11th and 18th January	 1993. The anxiety of the interveners	 was obvious. In no case their seniority should be disturbed and they be penalised for passing the examinations/interview tests and for coming into the cadre according to the rules through 9 the UPSC	 and no premium should be given to the applicants for their refusal to appear for the tests or for their failure to pass the same. This contention of their is unexceptionable and whether they had appeared in the case or not	 the Court was bound to protect their interests particularly when the matter was heard in their absence. The petitioner applicants	 however	 relied upon a decision of this Court in Dr. P.P.C Rawani & Ors. etc vs Union of India & Ors.	 (JT 1991 (6) 534). Shri Bhandare	 appearing for the petitioner applicants	 made a very fervent plea that in the circumstances	 the course adopted by this Court in Dr. Rawani 's case (supra) should be followed which will do no injustice to both the categories of direct recruits. We have gone through the said decision and have anxiously considered whether the course adopted there should be adopted in the present case. We are conscious of the fact that the petitioner applicants have been serving the Railways from the year 1968. It is also possible	 as contended on their behalf that many of the outside direct recruits have joined the service long after 1968 and some of them might have even taken initial instructions from the petitioner applicants. We are also conscious of the fact that candidates in service have a disadvantage as against the fresh candidates in the tests particularly when they face the tests after a long lapse of time. As against this	 however	 we cannot lose sight of the fact that the recruitment rules made under Article 309 of the Constitution have to be followed strictly and not in breach. If a disregard of the rules and the by passing of the Public Service Commissions are permitted	 it will open a back door for illegal recruitment without limit. In fact this Court has	 of late	 been witnessing a constant violation of the recruitment rules and a scant respect for the Constitutional provisions requiring recruitment to the services through the Public Service Commission. It appears that since this Court has in some cases permitted regularisation of the irregularly recruited employees	 some Governments and authorities have been increasingly resorting to irregular recruitments. The result has been that the recruitment rules and the Public Service Commissions have been kept in cold storage and candidates dictated by various considerations are being recruited as a matter of course. What is further	 in the present case	 some of those like the petitioner applicants who were initially recruited on ad hoc basis	 have exerted themselves and taken pains to appear for the tests before the UPSC and have enrolled themselves through regular channel unlike in Dr. Rawani 's case (supra). We have thus on hand three classes of 10 employees as pointed out earlier	 viz.	 the outside direct recruits	 the in service direct recruits and the ad hoc employees like the petitioner applicants who were regularised through the Court 's order. Further	 Dr. Rawani 's case (supra)	 as has been pointed out on behalf of the respondents	 pertains to the Central Government Health Services which has a larger component both at the initial and promotional stages. The course adopted by this Court to direct creation of supernumerary promotional posts at every higher promotional stage there	 may not be feasible in the medical service in the Railways. The creation of supernumerary posts has its own limitations	 both physical and financial. The burden of additional posts even when they are not necessary and cannot be accommodated	 is not easy to carry. We are	 therefore	 of the view that the direction given in Dr. Rawani 's case (supra) has to be confined to the special facts of that case and cannot be extended to other cases. In any case	 this court should not give any such direction to the Railways. If	 however	 the Railways decide to follow that course	 they can do so and nothing prevents them from doing it. We would rather refrain from creating a precedent by giving such directions. In the result	 we direct that the seniority of the direct recruits both outsiders and insiders should be determined according to the dates of their regular appointment through the UPSC and the petitioner applicants should be placed in the seniority list after those direct recruits who are recruited till this date. Among themselves	 their seniority will be governed by the dates of their initial appointment. The interlocutory application is disposed of in the above terms. G.N. Application disposed of.

The petitioner applicants were recruited by the Railways on ad hoc basis as Assistant Divisional Medical Officers between 1968 and 1984. Though UPSC recruited candidates on regular basis from time to time	 either due to non availability of number of candidates or non joining of selected candidates	 vacancies remained and persons like the petitioners continued in such vacancies on ad hoc basis. The petitioners riled Writ Petitions before this Court for regularisation of their services. By orders of this Court	 the services of the petitioners have already been regularised. The present application is for fixing the seniority of the Writ Petitioners whose services were regularised. Disposing of the application	 this Court	 HELD: 1. Since the petitioner applicants are admittedly not regularly appointed through the UPSC according to the rules but have been directed to be regularised by following the procedure laid down by this Court	 it is obvious that they are not appointed to their posts according to the rules. Under no circumstances	 therefore	 they fall within the scope of guidelines in Direct Recruit Class II Engineering Officers 'Association 's case. The expression "in accordance with the rules ' or 'according to rules" used in the said guidelines means the rules of recruitment and not the special procedure laid down by this Court The petitioner applicants thus fall in an altogether different category. Therefore	 a procedure for fixing their seniority has to be evolved. That procedure cannot be in violation of the guidelines laid down in Direct Recruit Class II Engineering Officers ' 2 Association 's case. Further	 the seniority given to the petitioner applicants will have to be below the seniority of the outsiders directly recruited through the UPSC as well as below that of the directly recruited erstwhile ad hoc Medical Officers. [8C F] Direct Recruit Class II Engineering Officers Association & Ors. vs State of Maharashtra & Ors. 	 ; 	 referred to. Of late this Court has been witnessing a constant violation of the recruitment rules and a scant respect for the Constitutional provisions requiring recruitment to the services through the Public Service Commission. Since this Court has in some cases permitted regularisation of the irregularly recruited employees	 some Governments and authorities been increasingly resorting to irregular recruitments. The result has been that the recruitment rules and the Public Service Commissions have been kept In cold storage and candidates dictated by various considerations an being recruited as a matter of course. [9E G] 2.2. What is further	 in the present case	 some of those like the petitioner applicants who were initially recruited on ad hoc basis	 have themselves and taken pains to appear for the tests before the UPSC and have enrolled themselves through regular channel. There are three classes of employees viz.	 the outside direct recruits	 the in service direct recruits and the ad hoc employees like the petitioner applicants who were regularised through the Court 's order. The direction given In Dr. Rawani 's case for creation of supernumerary posts has to be confined to the special facts of that case and cannot be extended to other cases. In any case	 this Court should not give any such direction to the Railways. If	 however	 the Railways decide to follow that course	 they can do so and nothing prevents them from doing it. This Court would rather refrain from creating a precedent by giving such directions. [9G H; 10A D] Dr A.K Jain & Ors. vs Union of India & Ors. [1987] Sapp. SCC 497 and Dr. P.P. C. Rawani & Ors etc. vs Union of India & Ors. 	 JT 1991 (6) 534	 referred to. The seniority of the direct recruits both outsiders and insiders 	should be determined according to the dates of their regular appointment through the UPSC and the petitioner applicants should be placed in the seniority list after those direct recruits who are recruited till date. Among 3 themselves	 their seniority will be governed by the dates of their initial appointment [10E]
