Summarize the following court judgment. n No. 43 of 1976. S.C. Agarwal for the Petitioners. 912 L.N. Sinha	 Sol Genl. and B. Datta for Respondents. The Judgment of the Court was delivered by BEG	 C.J. The petitioners before us are employees of the Forest Research Institute and Colleges Dehra Dun in the posts designated as Computers. Their grievance is that they should be treated as Research Assistants Grade II and given the same scale of pay and other conditions of service as are applicable to Research Assistants Grade II. The respondents	 Union of India and the President of the Forest Research Institute deny that the petitioners are entitled to be treated as Research Assistants Grade II. The petitioners rely upon certain alleged admissions on behalf of the oppo site parties	 on certain classifications of Computers in the past	 prior to the recommendations the Third Pay Commission 1973 as well as on the last mentioned report of the Central Pay Commission. Furthermore	 learned counsel has invited Union of India and another whereupon a Writ Petition by Computers	 they were shown as having been given identical scales of pay with the Research Assistants Grade II. This decision however	 does not deal with any controversy as to the correct classification of computers in comparison with Research Assistants Grade II. All we need say is that this case deals with the position under the Report of 1959 of ' the Second Pay Commission which has no bearing on the position which follows from the Report of the Third Pay Commission of 1973. Moreover	 it is evident that even at that time Research Assistants Grade II and Computer were shown as separate classes even though their pay scales and the revised pay scales were shown as identical. Thus the claim of the petitioners is that this Court should not only include the Computers amongst Research Assistants Grade II	 which is not borne out even from the Report of the Second Pay Commission	 but go further and equate their pays	 so that. even though they belong to different classes	 their scales of pay may be identical. We are afraid this is a matter which lay entirely within the sphere of the func tions of the Pay Commission. This Court cannot satisfactori ly decide such disputed questions on the salender material on which the learned counsel for the petitioner relies in order to displace what appears to us to be	 prima facie	 the effect of the Report of the Third Pay Commission of 1973. This report shows that Computers not only belong to a separate class of their own but received less pay than Research Assistants of Grade II. Learned Counsel for the petitioner 's tried to get out of the report of the Third Pay Commission contained in Chapter XVII relating to the Economists and Statisticians	 wherein Computers are mentioned and dealt with in paragraphs 32 to 34	 by asserting that their case should be covered by either Chapter XV	 which deals with "Scientific Services" (specifi cally mentioned therein) or Chapter XXI	 concerned with Ministry of Agriculture	 where the Forest Research Institute and Colleges are mentioned in paragraphs 58 onwards. It seems to us to be erroneous to attempt to place Computers in Chapter XV	 which deals with specified "Scientific Services" where Computers are not mentioned	 or in Chapter XXI	 which also does not mention Corn 913 puters at all. Learned Counsel for the petitioners tried to take advantage of the fact that paragraphs dealing with the Forest Research Institute in Chapter XXI do not mention Computers. It does not follow from this that Computers necessarily belong to the class into which the petitioners want to get in without showing what the criteria and func tions of persons entitled to be treated as Research Assist ants of Grade II are as compared with the Computers who	 prima facie belong to another class of workers dealing with statistics even though they may be in some way assisting in research or three may be some common functions. Indeed	 everyone working in a research institute could	 in some way	 be said to be assisting in research. We think that these are questions entirely unfit for determination upon a peti tion for a Writ for the enforcement of fundamental rights. It requires: firstly	 formulation of correct criteria for each classification; and	 secondly	 the application of these criteria to facts relating to the functions and qualifica tions for each class. The Pay Commission had done this elaborately. The learned Solicitor General has invited our attention to the case of Union of India vs G.R. Prabhavalkar & Ors. reported in ; 	 where this Court held that equation of posts is not a duty which the High Court was competent to carry out in proceedings under Article 226. We do not think that we have wider powers or that we can do with greater facility what a High Court cannot when exercis ing its writ issuing jurisdiction. The learned counsel for the petitioners has tried to take us at some length into the material on which he as sails the view taken by the opposite parties. We are unable to agree that	 on the material placed before us	 we can accept the petitioners ' interpretation of facts to which our attention was drawn. We are unable to consider other mate rial also to which our attention was attempted to be drawn because	 on the basis of the materials shown to us	 we are satisfied that such matters are not fit for determination by us on the kind of material sought to be placed before us. Finally	 learned counsel for the petitioners pleaded that we may permit him to raise this matter before an Admin istrative or Service Tribunal if and when one is constitut ed. It is not necessary for us to give him any permission to do that. We may however observe that the petitioners are at liberty to pursue other remedies	 including those which may be available to them if any such Tribunal is set up in future. We want to make it clear that the question whether there is or there is not enough material on record in a particular case to establish the basis of a particular discrimination is one of fact for the determination of which no hard and fast rules can	 be laid down. Moreover	 a dis crimination	 which involves the invocation of Article 14	 is not necessary covered by Article 16. We do not propose to discuss here the differences between Articles 14 and 16	 because we think that	 even the material relied upon on behalf of the petitioners before us shows that Computers and Research Assistants Grade II are classified separately. The validity of that classification cannot	 914 we think	 be displaced by the kind of evidence relied upon on behalf of the petitioners. And	 until that classifica tion is shown to be unjustified	 no question of violating Article 16 can arise. We	 therefore	 leave the petitioners to other means of redress if they still feel aggrieved. The result is that we dismiss the Writ Petition	 but make no order as to costs. S.R. Petition dis missed.

In the 1959 Second Pay Commission Report	 the pay scales and the revised pay scales of the Computers were shown as identical with that of the Research Assistants Grade II	 even though the 'two posts were shown as separate classes. The Third Pay Commission Report	 however	 showed that the Computers not only belonged to a separate class of their own but received less pay than Research Assistants ' Grade II. The petitioners assailed this view under article 32 of the Constitution as violative of Articles 14 and 16 of the Constitution on the ground that they had a Fundamental Right to be equated both in status as well as in Day to that of Research Assistants	 Grade II. Dismissing the petition the Court. HELD: (1) Equation of posts and equation of pay are matters entirely within the sphere of the function of the Pay Commission. These are questions entirely unfit for determination upon a petition for a writ for the enforcement of Fundamental Rights. It requires	 firstly	 formula tion of correct criteria for each classification. and	 secondly. the application of these criteria to facts relat ing to the functions and the qualifications for each class. The Pay Commission had done this in the instant case elabo rately	. B C] (2) The Court	 under article 32. neither has wider powers nor can do it with greater facility than a High Court can not	 when exercising its writ issuing jurisdiction. This Court had already laid down that equation of posts is not a duty which the High Court was competent to carry out in proceedings under article 226. [913 D] Union of India vs G.R. Prabhavalkar & Co. ; 	 referred (3) The question	 whether there is or there is not enough material on record in a particular case to establish the basis of a particular discrimination is one of fact for the determination of which no hard and fast rules can be laid down. A discrimination which involves the invocation of article 14 is not necessarily covered by article 16. In the instant case	 even the material relied upon by the petition ers shows the Computers and Research Assistants Grade II are classified separately	 and	 therefore	 the validity of that classification cannot be displaced by the kind of evidence relied on. Until that classification is shown to be unjus tified	 no question of violating Article 16 can arise. [913 G H	 914 A] Purshottam Lal and Ors. vs Union of India & Anr. held inapplicable.
