Summarize the following court judgment. Civil Appeal No. 282 of 1980. Appeal by special leave from the judgment and order dated the 29th March	 1980 of the Allahabad High Court (Lucknow Bench) know in Writ Petition No. 524 of 1979. AND CIVIL MISCELLANEOUS PETITION Nos. 4905 and 11949 of 1980. 463 G.N. Dixit	 Mrs. Shobha Dikshit and H.R. Bhardwaj for the Appellants. S.N. Kackar	 K.K Mohan	 Rajiv Datta and A.S. Pandit for the Respondent. A.N. Pareek and S.K Jain for the Intervener. The Judgment of the Court was delivered by MISRA	 J. The present appeal by special leave is directed against the judgment dated 29th March 1979 of the Allahabad High Court allowing a petition under Article 226 of the Constitution. In the State of Uttar Pradesh	 there is a Service commonly known as Naib Tehsildars. They have always formed the backbone of the revenue administration in that State. Sixty per cent of the posts of Naib Tehsildars are filled through a competitive examination held by the State Public Service Commission. The remaining posts are filled by promotion. There is another Service in that State known as the Service of Tehsildars. Cent percent of the posts of Tehsildars are filled by promotion from amongst various sources such as Naib Tehsildars	 Peshkars of the Kumaon Division	 Kanungos	 Kanungo Inspectors or Instructors and Sadar Kanungos. Ram Gopal Shukla	 the respondent	 started his service as Kanungo in 1949. In due course	 he was promoted as Naib Tehsildar. In 1962	 he was confirmed as such	 and in 1963 he was appointed as Tehsildar in an officiating capacity. It appears that a regular selection for the posts of Tehsildars was held in 1966 in accordance with the Uttar Pradesh Adheenasth Rajaswa Karyakari (Tehsildar) Sewa Niyamavali	 1966 (hereinafter referred to as 'the Tehsildar Rules 1966 '). Rule 5 of these Rules provides the sources of recruitment to the post of Tehsildar. Rule 6 thereof lays down conditions for eligibility and provides	 "For the purposes of recruitment to the Service a selection strictly on merit shall be made from amongst all the permanent Naib Tehsildars	 Tehsildars	 Peshkars of the Kumaon Division	 Kanungo Inspectors or Instructors and Sadar Kanungos	 who have put in not less than seven years ' service in the aggregate as such or in an equivalent or higher 464 post in a substantive or officiating capacity on the first day of January of the year in which the selection is made. " Rule 7 enjoins upon the Parishad to report by list of March every year to the Government the number of vacancies in the Service expected during the following calendar year	 and then provides that the Governor shall fix the number of appointments to be made. Rule 8 lays down the criterion for selection. Rule 9 prescribes the procedure for selection. As this rule is important for the purpose of the present case	 it is reproduced in so far as it is relevant	 "9. The procedure for selection shall be as follows: (1) The Parishad shall draw up	 in order of merit	 a list of most suitable candidates from amongst those who are eligible for promotion to the posts of Tehsildars. The names in the list shall ordinarily be double the number of substantive vacancies to be filled during the course of the year. (2) The Parishad shall also draw up	 in order of merit	 a supplementary list containing names of officials considered suitable for officiating or temporary vacancies expected to occur during the course of the year. (3) The two lists drawn up under clauses (1) & (2) above together with a gradation list prepared under clause (b) of Rule 10	 indicating therein the reasons for passing over the seniors	 if any and the character rolls of all the eligible officials shall be forwarded by the Parishad to the Commission . . . " (4) The Parishad shall thereafter	 in consultation with the Commission	 fix date	 on which a Selection Committee consisting of . . shall consider the cases of the eligible candidates whose names are contained in the final lists drawn up by the Commission and interview such of them as are indicated by the Commission under clause (3) above. (5) The lists of the names selected by the Committee shall be taken with him by the representative of the Commission 465 for placing them before the Commission	 and the Commission	 shall thereafter send their final recommendations to the Parishad. (6) The Parishad shall draw from the first list received from the Commission under clause (5) above	 as many candidates as there are permanent vacancies and will thereafter re arrange their names in accordance with their seniority in the present service and they will be appointed against the substantive vacancies. The remaining names of the first list and those of the second list will be regarded as forming the 'Select List ' to be drawn up in order of merit. The officials will be offered officiating or temporary vacancies in the order in which their names have been arranged in the aforesaid 'Select List ' as and when the vacancies occur during the course of the year. This 'Select List ' will hold good only for one year or until such time review is made at the following selection. (Emphasis supplied) (7) In case permanent vacancies do not occur for two consecutive years and it becomes necessary to make a selection for temporary or officiating vacancies only	 then also the procedure prescribed above will be followed." In accordance with the aforesaid rules	 the Uttar Pradesh Public Service Commission selected 148 persons for substantive appointment as Tehsildars and their names were shown in a list known as List A. The Commission also selected 300 other persons for temporary and officiating appointment as Tehsildars during the coming years and their names figured in what was called List B. The respondent was	 however	 not selected and consequently his name could not be included in either of the aforesaid two lists	 presumably because he had an adverse entry forming part of the remarks recorded on his work and conduct and had also been shown down below at serial No. 557 in the seniority list of Naib Tehsildars in the year 1956 Though the adverse entry was expunged in the year 1969 and his seniority was also re fixed at serial No. 216 on 6th of October 1970	 as there was no selection after 1966	 his name could not be included in either of the two lists. He has	 however	 no grievance on that account. Subsequently	 the State Government made the Uttar Pradesh Promotion by Selection in Consultation with Public Service Commission (Procedure) Rules	 1970 (hereinafter referred to as 'the 466 1970 Rules '). These rules govern various Services	 to be more specific 29 U.P. Services including the Service of Tehsildars. The purpose of these rules obviously was to standardise the procedure for promotion and make it uniform in respect of all such Services. The procedure laid down in the 1970 Rules for promotion as Tehsildar was not substantially different from that laid down in the Tehsildar Rules 1966. The respondent	 therefore	 did not feel aggrieved even by the introduction of the 1970 Rules. His grievance started only with the introduction of rules 7 A and 7 B to the 1970 Rules by notification No.42/4/1966 Apptt. 3 dated 4th of July 1972. As the question to be decided in this case is about the vires of rules 7 A and 7 B	 it will be appropriate to read them at this stage	 "7 A. Notwithstanding anything contained in these rules	 but subject to the proviso to rule 18	 the names of candidates on the Select List appointed in temporary or officiating vacancies prior to the date of issue of this notification	 shall be rearranged in order of seniority. " "7 B. The candidates of the Select List as rearranged in accordance with rule 7 A shall be appointed against substantive vacancies in preference to any candidate selected in accordance with the provisions of these rules. " The complaint of the respondent was that the aforesaid new rules 7 A and 7 B were discriminatory and violative of Article 14 and 16 of the Constitution	 in as much as the candidate in the Select List of 1966 were to be appointed against substantive vacancies in preference to any candidate selected in accordance with the provisions of the 1970 Rules and unless the candidates in the list were exhausted	 other eligible candidates were not to be considered for promotion so that their chances of promotion would be deferred to an undated future. The further grievance of the respondent was to the following effect. The Select List was to hold good only for one year or until such time a review was in made at the following selection. Thus	 the life of the Select List of 1966 was for one year only on the expiry of which it died its natural death. In this view of the legal position	 the appointment of Tehsildars from the Select List of 1966 after the expiry of a year from the date of its operation was illegal on the face of it. On the strength of Rule 7 A and rule 7B	 no selection was to be held unless 300 persons included in List were absorbed. The respondent challenged the vires of rules 7 A and 7 B by filing a petition under Article 226 of the Constitution in the High 467 Court of Allahabad. That petition was allowed in part and rules 7 A and 7 B were declared ultra vires Articles 14 and 16 of the Constitution in the impugned judgment. Shri Dixit	 appearing for the State has contended that a mere chance of promotion is not a condition of service giving rise to a fundamental right. We are afraid this contention is irrelevant to the decision of this case. The precise grievance of the respondent has been that he had a fundamental right of being considered for promotion when others similarly situated were so considered and that if he was not considered in a situation like that	 he was discriminated against and was denied equality of opportunity. This grievance	 if factually correct	 must be held to be well founded. It was next contended by Shri Dixit that the candidates covered by rule 7 A are a class by themselves	 that the classification is a reasonable classification and that as the respondent does not satisfy the requirements of rule 7 A	 he cannot claim that any infraction of Article 14 or 16 bas taken place. According to Shri Dixit	 two conditions are necessary to bring a person within the fold of that rule: (1) the candidate 's name must have been included in the Select List; and (2) he must have been appointed in a temporary or officiating vacancy prior to the date of issue of the notification of 4th July 1972. The respondent did not satisfy these requirements and therefore did not fall within the purview of rule 7 A. Rule 7 B gives preference to the candidates in the Select List as rearranged in accordance with rule 7 A	 which	 according to Shri Dixit	 was based on a reasonable classification and therefore the respondent can have no grievance. In support of this contention	 reliance has been placed on Reserve Bank of India vs C.S. Rajappan Nair and others	 State of Jammu & Kashmir vs Triloki Nath Khosa and others	 Ramesh Prasad Singh vs State of Bihar and others	 and Ganga Ram and others vs Union of India and others. In C.S. Rajappan Nair (supra)	 the classification of a group of employees who had officiated in a particular capacity as a different class	 treating them differently from others who had not the opportunity to function as such	 was held to be an intelligible differentia which can stand the test of equality provided by Article 16 of the 468 Constitution. In Triloki Nath Khosa (supra)	 persons appointed directly and by promotion had integrated into a common class of Assistant Engineers. The question arose whether for the purpose of promotion to the cadre of Executive Engineers	 they could be classified on the basis of educational qualification. It was held by this Court that the rule providing that graduates shall be eligible for such promotion to the exclusion of diploma holders did not violate Articles 14 and 16 of the Constitution. In Ramesh Prasad Singh (supra)	 this Court	 dealing with principle of equality under Articles 14 and 16	 observed	 "The doctrine of equality before law and equal protection of laws and equality of opportunity in the matter of employment and promotion enshrined in Articles 14 and 16 of the Constitution which is intended to advance justice by avoiding discrimination is attracted only when equals are treated as unequals or where unequals are treated as equals. The guarantee of equality does not imply that the same rules should be made applicable in spite of differences in their circumstances and conditions. Although Articles 14 and 16 of the Constitution forbid hostile discrimination	 they do not forbid reasonable classification and equality of opportunity in matters of promotion means equality as between members of the same class of employees and not equality between members of separate independent classes. . Equality is for equals	 that is	 who are similarly circumstanced are entitled to an equal treatment but the guarantee enshrined in Articles 14 and 16 of the Constitution cannot be carried beyond the point which is well settled by a catena of decisions of this Court " In Ganga Ram (supra)	 dealing with Articles 14 and 16 of the Constitution	 this Court again held	 "Mere production of inequality is not enough to attract the constitutional inhibition because every classification is likely in some degree to produce some inequality. The classification need not be scientifically perfect or logically complete. The matter has to be considered in a practical way without whittling down the equality clause. The classification must however be founded on intelligible differentia 469 which on rational grounds distinguishes persons grouped together from those left out	 and it must bear a just and reasonable relation to the object sought to be achieved. " There is no dispute with the principles of law laid down in the aforesaid cases. By now	 the principles of classification are well settled and need not be repeated. The question is of application of those principles to the facts of the present ease. The only basis for grouping the 300 persons in one category is that they were included in the Select List of 1966 and that they were officiating. The respondent in the instant case could not be selected in the selection of 1966 on account of an adverse entry which	 as stated earlier	 was subsequently expunged. His position in the seniority list was also corrected but because no selection took place after 1966 the respondent could not be included in the list for no fault of his. If there had been a selection and the list had been revised every year as is the requirement of the rules	 the respondent	 and like him many others	 would have been included in the list. For example	 some candidates who had not completed seven years could not be eligible for promotion and could not be included in the Select List of 1966 but after a lapse of time they became eligible and they might have been selected if selection had taken place. But	 the door for promotion had been of reclosed for the respondent and many others like him by rules 7 A and 7 B for no fault of theirs. In this connection reference may be made to the objection of the Public Service Commission and the letter of the Secretary of the Board of revenue	 to show that it would take. about 24 years to absorb 300 persons included in List B. The Secretary	 Board of Revenue	 vide his letter No. 14708/T.N.T. 59 A/70 dated 30th of January 1973	 to the Secretary	 Government Revenue Department (filed as Annexure II to the counter affidavit)	 recommended that the List may not be enforced. In so far as it is pertinent for the present purpose	 it reads	 "On the basis of the selection in the year 1966	 the List 'B ' was prepared for 300 names. During this period all the candidates of list 'B ' are working. So long as all these candidates are not absorbed in the regular vacancies	 the question of second selection does not arise till then. Only 56 vacancies have occurred after the selection of 1966. According to this the average vacancies in a year are at 10	 with the result	 it will take 24 years to exhaust the above list. Till then no selection is Possible. " 470 In the circumstances	 the Secretary requested the Government to take steps to recommend to the Public Service Commission to make the next selection of Tehsildars without any further delay. The objections of the Secretary	 Board of Revenue	 were similar to the objections raised by the Public Service Commission. These letters and objections point out unmistakably that the selection was unnecessarily postponed only to accommodate the 300 persons included in the Select List of 1966. There appears to be no rational basis for such a departure from the ordinary operation of the 1970 Rules which envisaged the preparation of a new list every year and for singling out one particular list for according preferential treatment to the persons whose names were contained therein. The classification in this case therefore cannot be said to be a reasonable classification based on intelligible differentia having a nexus to the object sought to be achieved. It is	 however	 contended for the State that the selection could not take place for all these long years because of a stay order passed by the High Court in petitions filed by some candidates challenging the Tehsildar Rules 1966. This has been refuted by Shri S.N. Kacker and a finding recorded by the High Court makes out that there was no order staying the holding of selection. All that was stayed was the confirmation of the officers promoted to the posts of Tehsildars. It is therefore not correct that selection could not take place because of a stay order from the High Court. As a second limb of this argument	 it was contended on behalf of the State that the Government was the sole judge of the administrative necessities and there being no rule to the contrary	 the Government could hold selection according to the need and no exception can be taken to the power of the State. There is no denying the fact that the rules regulating the conditions of service are within the executive power of the State or its legislative power under the proviso to Article 309 but even so	 such rules have to be reasonable	 fair and not grossly unjust	 if they are to survive the test of Articles 14 and 16 of the Constitution. A rule which contemplates that unless the list of 300 persons is exhausted no other person can be selected	 obviously is unjust and it deprives other persons in the same situation of the opportunity of being considered for promotion. 471 It was next contended for the State that the declaration of rules 7 A and 7 B as ultra vires the Constitution would affect not only the incumbents of one Service but of 29 Services and a fairly large number of persons would be affected in that situation	 that the respondent did not implead any of those persons likely to be affected in the various Services	 that in any case	 at least the Naib Tehsildars or other persons who have been promoted as Tehsildars and who are likely to be affected by the declaration of rules 7 A and 7 B as ultra vires should have been impleaded as parties and that in the absence of those parties	 the writ petition was not maintainable and should have been dismissed by High Court on that score. Shri S.N. Kacker appearing for the respondent	 on the other hand	 has contended that no such plea was taken on behalf of the State before the High Court and that	 therefore	 it cannot be permitted to take up a new plea for the first time before this Court. Elaborating the point	 Shri Kacker urged that if such a plea had been taken before the High Court	 the respondent would have impleaded all those persons as parties and filled up the lacuna	 if any	 and that if the State is permitted to take up such a plea for the first time before this Court	 it would seriously prejudice the case of the respondent. Alternatively	 it was contended that the respondent is aggrieved by the amendment of the 1970 Rules by the 1972 notification which introduced rules 7 A and 7 B	 that the respondent has challenged the vires of rules 7 A and 7 B and only the State is a necessary party who has already been impleaded	 and that at the most	 those persons who are likely to be affected in case the said rules are declared ultra vires	 may be proper parties but are not necessary parties. He sought to take support for his contention from B. Gopalaiah vs Government of Andhra Pradesh	 J.S. Sachdev & Ors. vs Reserve Bank of India & Anr.	 and General Manager	 South Central Railway	 Secundrabad & Anr. vs A . V. R. Siddhahi and Ors In Gopalaiah 's case dealing with a situation as in the present case	 the Andhra Pradesh High Court held	 "This is not a case of discrimination of individual against individual. This is a case where a whole class of citizens have been discriminated against and the court can not refuse to give relief to them on the ground that the 472 class of persons who will be benefited as a result of the discrimination are not before the Court. The person who complains of discrimination cannot be expected to search the country for all persons who are likely to be benefited by its discriminatory policy. Of course	 if the discrimination is in favour of an individual against an individual different considerations might arise. But this is not such a case. In my opinion	 where a scheme formulated by the Government is attacked on the ground of its being discriminatory the position is precisely the same as if a statute is attacked as being discriminatory and it can never be an answer to such an attack that persons likely to be benefited by a discriminatory statute should be brought before the Court before the statute is struck down." In J.S. Sachdev 's case (supra)	 a Division Bench of the Delhi High Court endorsed the view taken in Goplaiah 's case (supra). In South Central Railway 's case (supra)	 a similar objection taken before the Supreme Court was repelled on two grounds	 firstly	 because this point was not canvassed in the lower courts	 and secondly	 because the employees who were likely to be affected as a result of the re adjustment of the petitioner 's seniority were at the most proper parties and not necessary parties and their non joinder could not be fatal to the writ petition. In view of the law laid down in South Central Railway 's case (supra)	 the State cannot be permitted to take up a new plea which was not taken before the High Court. Shri B.P. Sharma had moved an application (C.M.P. No.49051.80) for permission to intervene in the appeal on the ground that he was vitally interested in the outcome of the instant appeal which would have a great bearing upon the claim petition pending before the Service Tribunal	 Lucknow. This application was ordered to be listed at the time of the hearing of this appeal. He also moved an application (C.M.P.No. 11949/80 for modification of the stay order dated 23rd of April 1980 in the appeal filed by the State	 so as to govern other cases affected by rules 7 A and 7 B of the 1970 Rules	 as amended by the 1972 notification. Later on	 he realised that such an application could not be moved on behalf of an intervener	 and therefore	 instead of pursuing this application	 he 473 filed Writ Petition No. 3806 of 1980	 which has been dealt with separately. Both these applications are	 therefore	 dismissed. For the reasons given above	 we find no error in the impugned judgment. We accordingly dismiss the appeal. Parties shall	 however	 bear their own costs. S.R. Appeal dismissed.

The selection for the posts of Tehsildars in the State of U.P. was to be made by promotion from amongst various sources such as Naib Tehsildars	 Peshkars of the Kumaon Division	 Kanungos	 Kanungo Inspectors or Instructors and Sadar Kanungos as per the procedure laid down in rules known as Uttar Pradesh Adheenasth Rajaswa Karyakari (Tehsildar) Sewa Niyamavali	 1966. The procedure for selection is regulated by Rule 9 and under sub section (6) of this Rule a select list will be drawn in order of merit separately for substantive vacancies and temporary vacancies and officials will be offered officiating or temporary vacancies in the order in which their names have been arranged in the "select list" as and when the vacancies occur during the course of the year. This "select list" will hold good only for one year or until such time a review is made at the following selections. Subsequently	 the State Government made the Uttar Pradesh Promotion by Selection in Consultation with Public Service Commission (Procedure) Rules	 1970	 which governed various services	 to be more specific 29 Uttar Pradesh services including the services of Tehsildars. The purpose of these rules was to standardise the procedure for promotion and make it uniform in respect of such services. The procedure laid down in the 1970 Rules for promotion as Tehsildars was not substantially different from that laid down in the Tehsildars Rules	 1966. By a Notification No. 4214/196. Appointment	 3 dated 4th July	 1972 two new rules were introduced	 namely	 Rules 7A and 7B	 in the 1970 Rules. As per these newly added rules candidates in the Select List made under the 1966 Rules were to be appointed against substantive vacancies in preference to any candidates selected in accordance with the provisions of the 1970 Rules and unless the candidates in the list were exhausted	 other eligible candidates were not to be considered for promotion so that their chances of promotion would be deferred to an undated future. 461 The respondent who started his service as Kanungo in 1949	 was promoted as Naib Tehsildar and in 1962 he was confirmed as such. In 1963	 he was appointed as Tehsildar in an officiating capacity. In accordance with the ]966 Rules the Uttar Pradesh	 Public Service Commission selected 148 persons for substantive appointment as Tehsildars and their names were shown in a list known as List A. The Commission also selected 300 other persons for temporary or officiating appointment as Tehsildars during the coming years and their names figured in what was called List B. The respondent was	 however	 not selected and his name could not be included in either of the aforesaid two lists because he had an adverse entry forming part of the remarks recorded on his work and conduct and had also been shown down below at serial 557 in the seniority list of Naib Tehsildars in the year 1966. Though the adverse entry was expunged in the year 1969 and his seniority was also re fixed at serial number 216 on 6th October	 1970	 since there was no selection after 1966	 his name could not be included in either of the two lists even thereafter. The respondent challenged the vires of Rules 7A and 7B by filing a petition under Article 226 of the Constitution in the High Court of Allahabad. That petition was allowed in part and Rules 7A and 7B were declared ultra vires Articles 14 and 1 6 of the Constitution	 in the impugned judgment. Hence the appeal by special leave by the State. Dismissing the appeal	 the Court	 ^ HELD: 1:1. Rules 7A and 7B of the Uttar Pradesh Promotion by Selection in Consultation with Public Service Commission (Procedure) Rules	 1970	 are ultra vires Articles 14 and 16 of the Constitution. [466 E	 473 A B] 1:2. The grievance of the respondent	 namely	 that he had a fundamental right of being considered for promotion when others similarly situated were so and that if he was not considered in a situation like that	 he was discriminated against and was denied equality of opportunity is not only factually correct but well founded. [467 B C] 2:1. It is true that the rules regulating the conditions of service are within the executive power of the State or its legislative power under the proviso to Articles 309 of the Constitution	 but even so	 such rules have to be reasonable	 fair and not grossly unjust if they are to survive the test of Articles 14 and 16 of the Constitution. A rule	 which contemplates that unless the list of 300 persons is exhausted no other person can be selected obviously	 is unjust and it deprives other persons in the same situation of the opportunity of being considered for promotion. [470 F H] 2:2. The classification in this case cannot be said to be a reasonable classification based on the intelligible differentia having a nexus to the object sought to be achieved. The only basis of grouping the 300 persons in one category is that they were included in the select list of 1966 and that they were officiating. The respondent	 in the instant case	 could not be selected in the selection of 1966 on account of an adverse entry which was subsequently expunged. His position in the seniority list was also corrected but because no selection took place after 1966. The respondent could not be included in the list for no fault of his. If there held 462 been a section and the list had been revised every year	 as is the requirement of the rules	 the respondent	 and like him many others	 would have been included in the list. For example	 some candidates who had not completed seven years could not be eligible for promotion and could not be included in the Select List of 1966 but after a lapse of time they became eligible and they might have been selected if selection had taken place. But	 the door for promotion had been foreclosed for the respondent and many others like him by Rules 7A and 7B for no fault of theirs. The objection taken by the Public Service Commission and the letter of the Secretary or the Board of Revenue addressed to the Government indicating that it would take about 24 years to absorb 300 persons included in List B and	 therefore	 recommending that the list may not be enforced would point out unmistakably that the selection was unnecessarily postponed only to accommodate the 300 persons included in the Select List of 1966. There is no rational basis for such a departure from the ordinary operation of the 1970 Rules which envisaged the preparation of a new list every year and for singing out one particular list for according preferential treatment to others in the similar situations [469 B F	 470 A C] State of Jammu and Kashmir vs Triloki Nath Khosa and others ; ; Ramesh Prasad Singh vs State of Bihar and others; 	 and Ganga Ram and others vs Union of India and others	 	 applied.

In a case where the vires of certain rules were challenged as being violative of the Articles 14 and 16 of the Constitution	 only State is a necessary party. The other persons likely to be affected by the declaration of the rules as ultra vires are only proper parties. [471 E F] 4.
