JUDGMENT: JUDGMENT [with Civil Appeal No. 4104 of 2002, Transferred Cases (Civil) Nos.  83 & 84 of 2005, Transferred Cases (Civil) Nos. 2, 3, 46, 47, 48, 49 &  50 of 2006 and Civil Appeal  No. \005\005\005 of 2007 (arising out of  SLP(C) No. 9239 of 2002)]

P.P. NAOLEKAR,J.

       Leave granted in S.L.P.(C) No. 9239 of 2002.          The appellants and the respondents herein are employees of  the Slum Wing Department  (hereinafter referred as "SWD").  SWD  was part of the Municipal Corporation of Delhi (hereinafter referred as  "MCD") before 1974.   SWD was transferred from MCD to Delhi  Development Authority (hereinafter referred as "DDA") in 1974 with  the stipulation that its employees alone would be considered for  confirmation and promotions against the posts in it.  In 1978,  SWD  was retransferred to MCD, but once again in May 1980 it was  transferred back to DDA with the stipulation that it would remain as a  separate entity and its employees would not be merged with DDA.   For recruitment of various staff members in DDA, vide its Resolution  No.574 dated 13.11.1963, DDA adopted Recruitment Rules of CPWD  qua the posts of Junior Engineer, Assistant Engineer and Executive  Engineer.  In the hierarchy of Engineering Cadre, the initial post is of  Junior Engineer (Section Officer or S.O.).  The post is meant for  100% direct recruitment and the qualification prescribed was  "Diploma-holders in Civil Engineering with two years’ experience".   However, there was no bar for persons possessing higher  qualification, viz., Degree in Engineering, for applying to the post of  Junior Engineer and such persons were not required to have any  prior experience for appointment to the cadre of Junior Engineer in  DDA.  The next higher post is that of Assistant Engineer.  The rule  provided filling up of 50% vacancies on the post of Assistant Engineer  by those who acquired a Graduate Degree in Engineering by means  of direct recruitment or by deputation.  The remaining 50% vacancies  were to be filled up on promotional basis from the pool of Junior  Engineers.  Out of 50% of the promotional feeder cadre of Junior  Engineers, one-half of such posts would be filled up by promotion of  diploma-holders with eight years’ qualifying service and remaining  50% quota would be filled up from the Junior Engineers who were  Graduate Engineering Degree-holders with three years’ qualifying  service.   Thus, the diploma-holders having eight years of qualifying  service and Graduate Engineering Degree-holders with three years’  qualifying service would be considered for promotion to the post of  Assistant Engineer within their quota of 25% each.  Further promotion  in the Engineering Branch is from the post of Assistant Engineer to  the post of Executive Engineer.  The minimum qualifying experience  for promotion to the post of Executive Engineer for graduate  Engineers is eight years’ experience in the grade of Assistant

Engineer, whereas for diploma-holders it is ten years’ service in the  grade of Assistant Engineer.    The appellants were graduates with Engineering Degree and  joined the Department as Junior Engineers as direct recruits.  On  7.6.1985 and 24.6.1985, some diploma-holder Junior Engineers were  promoted on ad hoc basis as Assistant Engineers.   

First phase of litigation

In the year 1984, the Junior Engineers and the Assistant  Engineers, who were diploma-holders, assailed constitutional validity  of the  rules in the matter of requirement of differential service  experience between the  graduates and the diploma-holders for  promotion to the higher cadres, viz., Assistant Engineers and  Executive Engineers respectively before Delhi High Court.  In W.P.  No.2132 of 1984 (Kimti Lal Kathuria and Others  v.  DDA), the  challenge was to the rule prescribing three years’ and eight years’  service experience for graduates and diploma-holders respectively to  the posts of Assistant Engineers and a discrimination thus brought  about between them.   W.P. No.2082 of 1984 (Niranjan Goel and  Others  v.  DDA) pertained to the constitutional validity of the  analogous provisions in the rules adopted by Resolution No.105  dated 16.6.1971.  The distinction made for promotion of degree- holder promotees and diploma-holder promotees was struck down by  Delhi High Court.  It was held that the diploma-holders should be  governed by the same eligibility promotional qualifications that were  applicable to degree-holders.  In W.P. No.2082 0f 1984, the Delhi  High Court struck down Resolution No.105 dated 16.6.1971 which  allowed DDA to distinguish between diploma-holder and degree- holder Assistant Engineers in the matter of experience and promotion  as Executive Engineers.  By a common judgment dated 2.9.1987  reported as Kimti Lal Kathuria and Others  v. Delhi Development  Authority and Others, 1988 Labour Industrial Cases 434 (Del) =  1988 (1) SLR 293, the Court  held that the prescription of differential  standards - based even on the differences in technical, educational  qualifications - is violative of Articles 14 and 16 of the Constitution.   However, in Roop Chand Adlakha and Others  v.  Delhi  Development Authority and Others, 1989 Supp.(1) SCC 116, a  two-Judge Bench of this Court reversed the above-mentioned  judgment  of the Delhi High Court.  

Second phase of litigation

       In 1971, the Departmental Promotion Committee (hereinafter  referred as "DPC"), appended a Note relaxing the rules in favour of  diploma-holders, who while in service acquired degree qualification,  so that they could be considered for promotion to the post of  Assistant Engineer on the following basis :-

1.      The period of three years should comprise of at  least two years after graduation plus 3/8 of the  service rendered in DDA or other government  organization or local body as S.O. subject to a  maximum of one year benefit.

2.      If a S.O., who has done graduation, completes eight  years’ service as S.O. on the date earlier than the  date on which the period of two years after  graduation expires, he should be given promotion  from such earlier date notwithstanding the fact that  he has not completed two years’ service after  graduation.

On 24.2.1989, S.P. Dubey, one of the respondents herein, filed a writ  petition (W.P. No.591 of 1989) before the High Court of Delhi and  challenged the validity of the above-mentioned Note, which was  adopted by the DPC in 1971.  It was contended that once a diploma- holder acquired a degree qualification, the entire experience gained  by him prior to obtaining the degree qualification should be counted  for considering the eligibility to the post of Assistant Engineer in  degree quota.   One Naresh Kumar Gera,  on 15.5.1989, filed another writ  petition (W.P. No.1427 of 1989) before the High Court of Delhi  against DDA and challenged the above-mentioned Note adopted by  the DPC in 1971 as arbitrary on the ground that it was not  proportionate to the length of service rendered as Junior Engineer  holding Diploma in Electrical Engineering and accordingly sought  quashing of the rules. In January 1990, Slum Wing Graduate Engineers’ Association  filed a writ petition (W.P. No.250 of 1990) before the High Court of  Delhi and sought direction against DDA to fill up posts of Assistant  Engineers belonging to degree-holders’ quota and claimed that  diploma-holders were much in excess of their quota.  The petitioners  therein alleged that the intention and the spirit behind the Recruitment  Rules was that there should be parity between the degree-holders  and diploma-holders in the matter of promotion to the post of  Assistant Engineer.   On 5.3.1991, a Division Bench of the High Court of Delhi  granted an interim order in W.P. No.250 of 1990 and directed DDA to  convene a DPC for each of the three years, i.e., January-1988, 1989  and 1990 in order that promotion be made and a parity of 1:1 is  maintained between the promotees.  The relevant observations of the  High Court in that regard are as follows:-

       "We are informed that after January, 1987 till today  no DPC has been held.  DPCs are required to be held at  least once a year.  This being so, we direct the DDA to  hold a DPC for each of the succeeding years, namely,  1988, 1989 and 1990 and make regular promotions of  eligible candidates in such a way that as far as possible  parity between the Degree-holders and the Diploma- holders is attained.  The regular promotions so made  shall, however, be subject to any direct recruitment, which  may be made in accordance with the rules against the  quota meant for direct recruits.  If as a result of such  direct recruitment, any of the promotees have to be  reverted then the reversion should be done in such a way  that the remaining Assistant Engineers who are  promotees should maintain the parity, namely 50% should  be from Degree-holders and 50% from Diploma-holders.   For the purpose of seniority at least, if not for other  benefits, about which we make no observations, the  promotions or regularization should be made with effect  from the date when the vacancies were available and the  candidates became eligible for promotion.  The DPC  should be convened within a period of six weeks from  today."

In the meanwhile, on 20.9.1990, a Memorandum was issued by   DDA which stipulated that a diploma-holder who had subsequently  acquired a Degree in Engineering would be treated as a degree- holder for the purposes of promotion, irrespective of the date of  acquiring graduate qualification.  It also stipulated that the  Recruitment Rules recognize only a ’Degree’ or a ’Diploma’ for  purposes of promotions and did not stipulate any minimum  experience after acquisition of ’Degree’.  It was further stated therein

4

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 4 of 18  

that even if an officer had acquired his degree just before the meeting  of DPC, he would be considered as a degree-holder for that and any  subsequent DPCs and the benefit of the past service would not be  available for reckoning seniority. On 1.5.1991, a DPC was held in which the appellants were  considered on the basis of their seniority. However, on 5.7.1991, by  giving effect to the Memorandum dated 20.9.1990, a fresh DPC was  convened which changed the seniority list in favour of the  respondents as a diploma-holder who had subsequently acquired a  Degree in Engineering would be treated as degree-holder for the  purposes of promotion, irrespective of the date of acquiring graduate  qualification.  The aforementioned Memorandum was challenged by way of   a writ petition (W.P. No. 3336 of 1990 -  R.K. Mittal & Another  v.   Union of India & Others) before a Single Judge of the Delhi High  Court.  By its judgment dated 19.8.1991 which was reported as 45  (1991) DLT 589, the High Court quashed the decision dated  20.9.1990 of DDA and allowed the writ on a limited ground that prior  to issuance of the said circular, principles of natural justice were not  complied with.  The relevant observations are as follows :-

" \005, I am of the view that the impugned decision  has been taken, in violation of the principles of natural  justice, as admittedly, no opportunity of being heard was  given to the Degree-holders, as well as, the Diploma- holders.  The result is that in my opinion, the case should  be remanded back to the DDA, for taking the decision  afresh, after inviting objections, or comments, both from  the Degree-holders and Diploma-holders Junior  Engineers.  The representatives of both these categories  be also given opportunity of being heard.  After this, it is  for the DDA to interpret or clarify the rules."

" \005 The impugned decision dated September 20,  1990, is quashed and set aside.  I remand the matter  back to the DDA, with direction to decide the matter  afresh, within a period of six months, after inviting  objections / comments from all concerned and after giving  an opportunity of being heard, to the representatives of  Degree-holder and Diploma Holder Junior Engineers."

The diploma-holders by way of a Letters Patent Appeal (L.P.A. No.  43 of 1991) challenged the decision of the Single Judge dated  19.8.1991.   On 5.2.1991, an Establishment Order was issued to  promote diploma-holders on current duty charge basis.  The same  was questioned by filing a writ petition (W.P. No. 2382 of 1991 - Slum  Wing Delhi Development Authority Graduate Engineers’  Association (Regd.) & Others  v.  D.D.A. & Others).  By its decision  dated 12.2.1992 reported as 46 (1992) DLT 486 (DB) = 1992 (22)  DRJ 548,  the Delhi High Court’s Division Bench dismissed the LPA  and allowed the writ petition holding that three years’ experience  required for degree-holders’ eligibility quota had to be considered  after acquiring the degree.  The High Court summarized the issues as  follows :-

       "Herein, the main controversy is whether a Diploma  holder Junior Engineer, who obtains degree while in  service becomes eligible for promotion as Assistant  Engineer on rendering three years’ service would include  therein the period of service rendered by him prior to the  obtaining of the Degree or he has to render three years’  service after obtaining the Degree to become eligible for  promotion to the post of Assistant Engineer\005

\005Here the only point for our consideration is whether  three years service as Junior Engineer has to be after  obtaining degree or the earlier service of the Junior  Engineer while holding diploma only can also be  considered"

The Division Bench of the High Court relied upon the  observations of this Court as propounded in N. Suresh Nathan and  Another  v.  Union of India and Others, 1992 Supp.(1) SCC 584  wherein the Court has observed that Rule 7 lays down the  qualifications for direct recruitment from the two sources, namely,  degree-holders and diploma-holders with three years’ professional  experience.  In other words, a degree is equated to diploma with  three years’ professional experience.  Rule 11 provides for  recruitment by promotion from the grade of Section Officers (now  called Junior Engineers) which provides two categories of Junior  Engineers, i.e., degree-holder Junior Engineers with three years’  service in the grade and the diploma-holder Junior Engineers with six  years’ service in the grade and promotional quota of 50% from each  category which matches with Rule 7 wherein a degree is equated  with diploma with three years’ professional experience.   The entire  scheme, therefore, does indicate that the period of three years’  service in the grade required for  degree-holders according to Rule 11  as the qualification for promotion in that category must mean three  years’ service in the grade as a degree-holder and, therefore, that  period of three years can commence only from the date of obtaining  the degree and not earlier and this interpretation of Rule 11 is quite  tenable and commends to us being in conformity with the past  practice followed consistently.  It has also been so understood by all  concerned till the raising of the present controversy. On 25.2.1992, one of the respondents herein S.P. Dubey and  others challenged the abovementioned judgment of the Delhi High  Court dated 12.2.1992 before this Court by way of  Special Leave  Petition (Civil) Nos. 7737-39 of 1992.  The DDA also filed Special  Leave Petitions (Civil) Nos. 7114-16 of 1992 against the aforesaid  judgement.  This Court dismissed these petitions vide order dated  20.8.1992 in limine. Pursuant to the directions contained in the judgment dated  12.2.1992 of the Division Bench of the Delhi High Court, DDA by a  circular dated 30.10.1992 issued tentative seniority list of the  Engineers and indicated their placement as per their eligibility for  promotion as Assistant Engineer upto 15.10.1992.  On 19.3.1993, the  final seniority list of graduate Junior Engineers (Civil) indicating their  placement as per eligibility for promotion as Assistant Engineer (Civil)  was circulated.  On 22.3.1993, the appellants were promoted as  Assistant Engineers (Civil) on the recommendations of DPC against  the vacancies arising during calendar year spanning from 1.1.1988 to  1992 as per the seniority list prepared by the Department in  accordance with the judgment dated 12.2.1992 of the High Court.   The seniority list so drawn was based on two principles, namely,

1.      The date on which the selection panel of Degree- holders was approved for appointment as Junior  Engineers, and

2.      The date of acquisition of degree by a Diploma- holder Junior Engineer working in the Department,

Provided that the persons in (1) above would  maintain their inter se seniority by the selection  panel;

Provided further that if there are more than one  Diploma-holder Junior Engineer acquiring degree as in (2)  above, then they will be assigned inter se  seniority  according to the order in which their names figure in 1987

list.

On 22.3.1993, the Department issued a corrigendum with  regard to the seniority position. SWD was transferred to MCD on 1.9.1992 and hence the  appellants moved an application before the High Court.  The High  Court passed an order on 21.9.1992 that in view of the transfer, the  decision of the High Court dated 12.2.1992 would be implemented by  MCD within three months from 21.9.1992. One of the respondents herein \026 S.P. Dubey - through writ  petition before the High Court of Delhi (W.P. No. 1664 of 1993),  prayed for quashing the above-mentioned seniority list and sought for  a direction that promotions to the post of Assistant Engineers be  made on the basis of the seniority list issued by the authority in 1984  and 1987.  Several other writ petitions were filed before the High  Court of Delhi, which questioned the above-mentioned seniority list.   S.P. Dubey and others through another writ petition before the High  Court of Delhi (W.P. No.1923 of 1993) prayed for quashing the  promotions to the post of  Assistant Engineers made by MCD vide  orders dated 22.3.1993.   On 12.3.2001, a Division Bench of the Delhi High Court vide  its  order referred Civil Writ Petition Nos. 591 of 1989, 1427 of 1989,   1664 of 1993 and 1923 of 1993 along with some other petitions for  decision by a Bench of three Judges of the High Court in view of the  fact that it felt that the earlier decision of the High Court dated  12.2.1992 in Slum Wing Delhi Development Authority Graduate  Engineers Association (Regd.) & Others  v.  D.D.A. & Others  (supra), which followed the decision of this Court in N. Suresh  Nathan and Another  v.  Union of India and Others (supra),  required to be considered as N. Suresh Nathan’s Case had not  been subsequently followed by this Court in other cases like M.B.  Joshi and Others  v.  Satish Kumar Pandey and Others, 1993  Supp. (2) SCC 419; D. Stephen Joseph  v.  Union of India and  Others,  (1997) 4 SCC 753; Anil Kumar Gupta and Others  v.   Municipal Corporation of Delhi and Others, (2000) 1 SCC 128;  and A.K. Raghumani Singh and Others  v.  Gopal Chandra Nath  and Others, (2000) 4 SCC 30 as regards the applicability of eligibility  criteria in the Recruitment Rules for promotion to the post of the  Assistant Engineer.  Accordingly, the matter was placed before the Full Bench of the  Delhi High Court.  The present appeals by special leave have been  filed before this Court against the interim and common order dated  25.1.2002 passed by the Full Bench of the Delhi High Court.  The Full  Bench of the Delhi High Court after consideration of the relevant  decisions, the rule in question and the facts found from the record  has recorded the findings that (i) it cannot be said that the DDA  followed a consistent practice to the effect that experience for the  purpose of promotion to the post of Assistant Engineer would be  counted only after a candidate acquires a degree; and (ii) the Note  which was issued by DPC in 1971 was in violation of the statutory  rules dated 13.11.1963.  It was observed that DPC had no requisite  jurisdiction therefor, the same had not been approved by the DDA  and such Note was ultra vires.  Consequently, the appropriate  practice which was followed pursuant to the Note of 1971 till  6.12.1982 was held to be wholly illegal and without jurisdiction and  thus in the eye of law to be non est.  The issue of res judicata was  decided in the light of the aforementioned findings.  With reference to  the Note issued by the DPC in 1971, it was observed that in a case  where the fundamental right of a person, by reason of a wrong  interpretation of  statute would be taken away, which would render a  decision nullity, cannot operate as res judicata.  It was further said  that a candidate in terms of Article 16 of the Constitution of India does  not have a right to promotion, but he has the fundamental right to be  considered therefor.  Right to be considered in terms of Article 16

7

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 7 of 18  

would embrace within its fold consideration in accordance with law  and in a fair, just and equitable manner.  If a candidate is deprived of  his right to be considered for promotion on misinterpretation and  misconstruction of a statutory provision, the same in the  aforementioned situation would attract the wrath of Article 16 and on  that ground an earlier decision would not attract the principle of res  judicata. An unreasoned order at the threshold does not constitute a  binding precedent nor would such an order operate as res judicata.   As for the interpretation of the rule regarding the past service of the  diploma-holders, the Court held that the diploma-holders and the  degree-holders were at par.  The educational qualification was to be  considered for the purpose of eligibility alone.  Once it is held that  both the degree-holders and the diploma-holders had been  performing the same type of functions, there cannot be any doubt  whatsoever that their experience would be counted for the purpose of  their promotion irrespective of their educational qualification.  As and  when diploma-holders acquire qualification, only then they become  eligible for consideration in the degree-holders’ quota.  It was  observed that it was idle to contend that any anomaly existed and the  answer to the question referred to the Full Bench was in the following  terms:   

1.      Principle of res judicata in the instant case has no  application; and,  

2.      The experience gained by diploma-holders as Junior  Engineer has to be counted for promotion to the post  of Assistant Engineer, in the event they are duly  qualified as degree-holders;

and the matter was remitted back to the Division Bench for  consideration of the cases in the light of the findings arrived at by  the Full Bench.               In the present case, we are concerned with the rule relating  to promotion from the post of Junior Engineer to the post of  Assistant Engineer.             It is urged by Shri Jawahar Lal Gupta and Dr. Rajeev  Dhavan, the learned senior counsel for the appellants, that under  the promotion rule promotion to the post of Assistant Engineer two  separate channels are provided for diploma-holders and degree- holders within their respective quota and there would be no  violation of rules if requisite experiences required on the post of  Junior Engineer as diploma-holder and degree-holder are treated  differently and it would be open for the Government to lay down  and treat different period of experience as qualitatively different for  two classes for further promotion to the post of Assistant Engineer.             On the other hand, it is urged by Shri G.D. Gupta, the  learned senior counsel for the respondents, that 50% of the  promotion quota for degree-holders Junior Engineers is provided  under the rules irrespective of the fact whether a person has  joined the post of Junior Engineer as a degree-holder or a  diploma-holder and, therefore, on correct interpretation of the rule  the period of three years’ experience required is inclusive of the  period of service on the post prior to the acquisition of the degree  qualification.  The plain meaning of the words in the rule suggests  only one interpretation that two qualifications, namely, Degree in  Engineering and three years’ service are disjunctive.  Therefore, a  Junior Engineer who obtains degree while in service, is required to  satisfy only two requirements to become eligible for promotion to  the post of Assistant Engineer, i.e., a Junior Engineer should have  Degree in Engineering or its equivalent qualification in addition to  three years’ service experience as Junior Engineer.  The rule  refers to three years’ service experience on the post of Junior  Engineer and not the experience as qualified degree-holder Junior  Engineer.  It is further urged that even otherwise for appointment

8

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 8 of 18  

to the post of Assistant Engineer by direct recruitment, the  qualification required is Degree in Engineering without there being  any requirement of experience, which shows that the degree- holder with no prior experience is considered competent to  perform the duties attached to the post of Assistant Engineer.   There can be no justification that for promotion to the post of  Assistant Engineer, a Junior Engineer must possess three years’  service experience as Junior Engineer after obtaining Degree in  Engineering.  While construing the relevant rule, the Court has to  take into consideration the fact situation in the service and on due  consideration of the facts the experience required for promotion  could only mean the experience on the post of Junior Engineer  and not after obtaining the degree for the purpose of promotion in  the quota of degree-holders.   Large number of authorities are cited by learned counsel  appearing for both sides raising various issues, viz., whether a  diploma-holder after obtaining a degree would be compulsorily  shifted to the group of graduate Engineers giving a go-by to their  claim for promotion to diploma-holders quota or they have a choice  to select and continue with either of them.  What should be the  seniority position of the diploma-holders after they have qualified  as graduates, etc.  We have refrained ourselves from expressing  any opinion on these points and have confined ourselves to the  specific issue raised before us and answered by the High Court in  the impugned judgment.                 In the matter of N. Suresh Nathan and Another  v.   Union of India and Others, 1992 Supp. (1) SCC 584, a three- Judge Bench was called upon to decide a similar question as  involved in the present case, namely, whether the three years’  service experience for promotion for graduate Engineers would  mean three years’ service prior to obtaining the degree or three  years’ service after obtaining the degree.  The relevant Rule 11  provided for recruitment by promotion from the grade of Junior  Engineers.  Two categories were provided therein, viz., one of  degree-holder Junior Engineers with three years’ service in the  grade and the other of diploma-holder Junior Engineers with six  years’ service in the grade, the provision being for 50% from each  category.  While interpreting the rule, this Court said that the entire  scheme did indicate that the period of three years’ service in the  grade as a degree-holder and, therefore, that period of three years  can commence only from the date of obtaining the degree and not  earlier.  The service in the grade as a diploma-holder prior to  obtaining the degree cannot be counted as service in the grade  with a degree for the purpose of three years’ service as a degree- holder.  The Court observed as follows: "4.     In our opinion, this appeal has to be allowed.  There  is sufficient material including the admission of  respondents diploma-holders that the practice followed in  the department for a long time was that in the case of  diploma-holder Junior Engineers who obtained the degree  during service, the period of three years’ service in the  grade for eligibility for promotion as degree-holders  commenced from the date of obtaining the degree and  the earlier period of service as diploma-holders was not  counted for this purpose.  This earlier practice was clearly  admitted by the respondents diploma-holders in para 5 of  their application made to the Tribunal at page 115 of the  paper book.  This also appears to be the view of the  Union Public Service Commission contained in their letter  dated December 6, 1968 extracted at pages 99-100 of the  paper book in the counter-affidavit of respondents 1 to 3.   The real question, therefore, is whether the construction  made of this provision in the rules on which the past  practice extending over a long period is based is  untenable to require upsetting it.  If the past practice is

9

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 9 of 18  

based on one of the possible constructions which can be  made of the rules then upsetting the same now would not  be appropriate.  It is in this perspective that the question  raised has to be determined."

            From a reading of the aforesaid judgment, it is apparent that  after construing the relevant rule the Court has found that the past  practice followed in the Department is consistent with the  interpretation provided to the relevant rule by the Court.              The same question once again came before another two- Judge Bench of this Court in M.B. Joshi and Others  v.  Satish  Kumar Pandey and Others, 1993 Supp. (2) SCC 419.  This time  an interpretation was required with reference to a quota of 10% for  the graduate Sub-Engineers completing eight years of service.   The relevant rule provided for Sub-Engineers to qualify for  promotion to the post of Assistant Engineer and qualifying service  provided was twelve years for diploma-holders and eight years for  such Sub-Engineers who had obtained Degree of Graduation in  the course of service.  By an Executive Order, 50% of the quota  was provided for direct recruits and the balance 50% quota by  promotion was sub-divided prescribing 35% for diploma-holders  completing twelve years of service, 5% for Draftsmen and Head  Draftsmen completing twelve years of service and 10% for  graduate Engineers completing eight years of service.  The Court  was called upon to consider whether the period of eight years can  only be counted from the date when the diploma-holder Sub- Engineers acquired the Degree of Engineering and not prior to the  said date.  The controversy arose between the parties is  summarized in paragraph 5 of the judgment as under :-         "The short controversy arising in these cases  relates to the determination of seniority amongst the  diploma-holder Sub-Engineers who acquired the degree  of graduation in engineering during the period of service  qualifying them for promotion in 8 years to the post of  Assistant Engineer. \005"

From the aforesaid, it is clear that the Court was considering the  experience/qualifying service of eight years and twelve years  amongst the diploma-holder Sub-Engineers and not vis-‘-vis the  degree-holder Sub-Engineers.  The reduction of the qualifying  service from twelve years to eight years simply accelerated the  entitlement to promotion for the post of Assistant Engineer by Sub- Engineers from twelve years to eight years.  The qualifying service  which was required to be considered under the rule was that of  diploma-holder Sub-Engineers. The qualifying service has no  relation with the Degree of Engineering and it is said by the  judgment in N. Suresh Nathan’s case (supra)  that the rule does  not contemplate any equivalence of any period of service with the  qualification of acquiring Degree of Graduation in Engineering.                 In paragraph 11 of the judgment, the  Court  discussed  the ratio and held :-         "A perusal of the above observations made by this  Court clearly show that the respondents diploma-holders  in that case had admitted the practice followed in that  department for a long time and the case was mainly  decided on the basis of past practice followed in that  department for a long time.  It was clearly laid down in the  above case that if the past practice is based on one of the  possible constructions which can be made of the rules  then upsetting the same now would not be appropriate.  It  was clearly said "it is in this perspective that the question  raised has to be determined".  It was also observed as  already quoted above that the Tribunal was not justified in  taking the contrary view and unsettling the settled practice  in the department.  That apart the scheme of the rules in

10

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 10 of 18  

N. Suresh Nathan case  was entirely different from the  scheme of the Rules before us.  The rule in that case  prescribed for appointment by promotion of Section  Officers / Junior Engineers provided that 50 per cent  quota shall be from Section Officers possessing a  recognized degree in Civil Engineering or equivalent with  three years’ service in the grade failing which Sections  Officers holding Diploma in Civil Engineering with six  years’ service in the grade.  The aforesaid rule itself  provided in explicit terms that Section Officers possessing  a recognized Degree in Civil Engineering was made  equivalent with three years’ service in the grade.  Thus, in  the scheme of such rules the period of three years’  service was rightly counted from the date of obtaining  such degree.  In the cases in hand before us, the scheme  of the rules is entirely different".

In the above decision (i.e. M.B. Joshi’s case), the matter of N.  Suresh Nathan (supra) was distinguished mainly on the basis of  past practice and the Court further held that the rule under  consideration in N. Suresh Nathan (supra)  was entirely different  from the scheme of the rule which the Court was considering in  M.B. Joshi (supra).  We have carefully considered the case of N.  Suresh Nathan and it is not correct to say that the decision  rendered in that matter was based on past practice.  The Court,  in fact, has considered and interpreted the relevant service rules  and then found that such an interpretation is fortified by the  practice followed in that department.                   Similar issue once again came before a two-Judge  Bench of this Court in D. Stephen Joseph  v.  Union of India  and Others, (1997) 4 SCC 753.  The exact question was as  follows :-

       "\005..whether for promotion to the post of Assistant  Engineer in the 50% promotion quota reserved for the  person possessing degree in Electrical Engineering from  a recognized University or an equivalent with three years’  regular service in the grade of Junior Engineers in the  Electricity Department, Government of Pondicherry, three  years’ experience as Junior Engineer in the grade is to be  counted from the date of acquisition of the degree in  Electrical Engineering or the length of service in the grade  of Junior Engineers is to be reckoned if the incumbent at  the time of promotion to the 50% quota also possesses  degree in Electrical Engineering."

              The ambit of  N. Suresh Nathan’s case (supra) is  explained in D. Stephen Joseph (supra),  wherein it is said in  paragraph 5 that the State Government is labouring under a  wrong impression as to the applicability of the past practice as  indicated in N. Suresh Nathan’s case.  This Court, in the said  decision, has only indicated that the past practice should not be  upset if such practice conforms to the rule for promotion and  consistently followed for some time past.  The rule has been  interpreted in a particular manner and N. Suresh Nathan’s case  only indicates that past practice must be referable to the  applicability of the rule as interpreted by the Court’s order in a  particular manner consistently for some time and would lend  support to the interpretation of the rule. The Court emphasized  that any past practice de hors the rule cannot be taken into  consideration as past practice consistently followed for long by  interpreting the rule and N. Suresh Nathan’s case was  distinguished in the facts of that case and the language of the

11

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 11 of 18  

rule which came up for consideration. D. Stephen Joseph  (supra) provides for promotion to 50% quota from Junior  Engineers possessing Degree in Electrical Engineering from a  recognized university with three years’ regular service in the  grade of Junior Engineers.  On the plain language of the rule, this  Court has held that the requirement of the rule is three years’  experience as Junior Engineer in the grade and not the  acquisition of Degree in Electrical Engineering.  Thus, it cannot  be said that in M.B. Joshi and D. Stephen Joseph (supra)  the  Court  has  taken  a different view than what was taken by a       3-Judge Bench in N. Suresh Nathan’s case.   In N. Suresh  Nathan’s  case,  the Court has interpreted the rule which  provides for a particular length of service in the feeder post as  qualifying service completed with  educational qualification to  enable the candidates to be considered for promotion and, thus  the experience so obtained in the service would necessarily  mean the experience obtained after the requisite qualification  was acquired. Thus, the decision turns on the language of the  rule and has distinguished N. Suresh Nathan’s case on that  basis.                 In Anil Kumar Gupta and Others  v.  Municipal  Corporation of Delhi and Others, (2000) 1 SCC 128, the  relevant rules which came up for consideration provided for  essential qualification for appointment, viz., (a) Degree in Civil  Engineering ; and (b) two years’ professional experience.  The  age was not to exceed 30 years (relaxable for government  servants and MCD employees).  The applications were received  for appointment to the post of Assistant Engineer (Civil)  in the  Engineering Department of MCD.  The applications were  received from the departmental candidates as well as others.   The Selection Board of MCD had prescribed the norms for  awarding marks.  So far as the experience part was concerned,  break-up was :  Upto two years experience - ’no marks’; 3 to 12  years’ and above experience at the rate of  =  mark,  i.e., for 10  years -  5 marks;  and Viva-voce -  15 marks.  The question  for  consideration was whether the pre-degree experience of the  candidates can be taken into consideration for awarding the  marks or whether the candidate’s experience gained after  obtaining the degree is to be taken into consideration for  awarding the marks.  In paragraph 20 of the judgment, the Court  has said that the provision regarding experience speaks only of  professional experience of two years and does not, in any  manner, connect it with the degree qualification.  Further, the  Court has considered N. Suresh Nathan’s case (supra) and  said in para 22 that N. Suresh Nathan’s case was based initially  on the practice followed in the department over a long number  of  years when the rules were understood as full service of three  years after obtaining the degree and on that basis it was held  that the service was not to include the service while holding a  diploma.  In paragraph 23, the Court cautioned that any practice  which is de hors  the rules can be no justification for the  department to rely upon.  Such past practice must relate to the  interpretation of the rule in a particular manner and while  interpreting the language of the notification, the Court held that  two years’ professional experience need not entirely be the  experience obtained after obtaining the degree.  Requirement is  only degree and two years’ professional experience and not the  experience as degree-holder.  We are afraid that the observation  of the Court that N. Suresh Nathan’s case was decided mainly  on the past practice followed in the department, would not be a  correct reading of N. Suresh Nathan’s case.  This case was   essentially decided on the interpretation of the rule and the court   found support to that interpretation from the past practice  followed in the Department.    Thus, it appears from this  judgment that essentially N. Suresh Nathan’s case was not

12

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 12 of 18  

followed on the interpretation of the rule, which came in question  for consideration before the Court and it was held that the  professional experience required cannot be read to have any  connection with the Degree in Civil Engineering and, therefore,  the professional experience in service irrespective of a Degree in  Civil Engineering would be considered for allotting marks by the  Selection Board.               A two-Judge Bench of this Court gave its considered  opinion on the subject by means of interpretation of the word  ‘with’ that appeared before the stated requirement of given  period of experience in A.K. Raghumani Singh  and Others  v.   Gopal Chandra Nath and Others., (2000) 4 SCC 30.  The Court  considered the rules called "The Manipur PWD/Irrigation and  Food Control/Public Health Engineering (Superintending  Engineer (C)/Superintending Surveyor of Works) Recruitment  Rules" wherein it is provided that the post of Superintending  Engineer shall be filled up by promotion from Executive Engineer  and Surveyor of Works possessing Degree in Civil/Mechanical  Engineering or its equivalent from a recognised institution with  six years’ regular service in the grade.  The contention was that  six years’ regular service in the grade as eligibility criteria should  be after the educational qualification was obtained.  The Court  interpreted the rules and said that the rule prescribed the  eligibility criteria to be a prescribed educational qualification and  six years’ experience as well.  Giving a plain meaning to the  phrase, it would not be justified in reading ’a qualification’ into a  conjunctive word and imply the word ’subsequent’  after the word  ’with’.  The Court was of the view that six years’ regular service in  the grade would not mean the service subsequent to obtaining  the prescribed educational qualification.  Para 9 of the judgment  gives the Court’s reasoning as follows :-         "Even on a point of principle it would be  unreasonable to distinguish between the nature of the  regular service required, as if the service in the grade  subsequent to the obtaining of the necessary educational  qualification were qualitatively different from the service in  the grade prior thereto.  In fact no such case has been  made out."

The decision rendered by the Court is based on interpretation of  the rule.             In Indian Airlines Ltd. and Others  v. S. Gopalakrishnan,  (2001) 2 SCC 362, a Division Bench of this Court had an  occasion to consider the relevant Service Rules in the fact  situation where the Indian Airlines Ltd. had invited applications  for the post of Junior Operator.  The respondent, who made an  application for the said post, possessed an ITI certificate since  1994 and a Diploma in Mechanical Engineering.  Under the  relevant rule, the qualification prescribed was ‘SSC or its  equivalent with three years’ Government-recognized diploma in  Mechanical/Electrical/Automobile Engineering and having two  years’ experience in equipment operations or driving and  possessing current heavy vehicle driving license’ or ‘ SSC with  ITI certificate or equivalent in associated trades of  mechanical/electrical/automobile courses and having five years’  experience in equipment operating or driving and possessing  current heavy vehicle driving license’.   The Court said that when  in addition to qualification, experience is prescribed, it would only  mean acquiring experience after obtaining the necessary  qualification and not before obtaining such qualification.  In the  case of the respondent, he obtained the ITI certificate in 1994  and, therefore, did not possess five years of experience as  required under the relevant rule.   The experience required to be  gained by a candidate of five years was held to be after obtaining  the requisite qualification.

             From a reading of the decisions rendered by this Court,  one thing is clear to us that the decisions in N. Suresh Nathan,  M.B. Joshi, D. Stephen Joseph, Anil Kumar Gupta, A.K.  Raghumani Singh and Indian Airlines Ltd. (supra), are based  on the interpretation of the respective rules called in question,   giving meaning to the words used in the context of the entire  scheme governing service conditions and the facts involved in  each case and it cannot be said that the decisions rendered by  this Court after the decision of N.Suresh Nathan’s case, have  taken a different view than what has been decided in N.Suresh  Nathan’s case.  Thus, we are required to decide the matter on  the basis of the entire scheme of the rules, the facts and  circumstances at the relevant time and the rules called in  question before us, independently giving meaning to the words,  the principle involved and the past practice, if any, which is in  consonance with the interpretation given by us to the rule.  If we  find that two views are possible after interpreting the rule, then  the rule would be interpreted keeping with the practice followed  in the Department for a long time and thus the practice practically  acquired status of rule in the Department. The only question involved in these appeals and transferred  cases can be stated thus : Whether a diploma-holder Junior  Engineer, who obtains a degree while in service, becomes eligible  for promotion to the post of Assistant Engineer on completion of  three years of service after he obtained the Engineering Degree or  on completion of three years of service prior to obtaining the  Degree in Engineering.       The following table shows the effect and intent of the rules  adopted under Resolution Nos.574 and 105 dated 13.11.1963 and  16.6.1971 respectively.  It also shows the manner of initial  recruitment to the cadre of Junior Engineers:

Executive Engineers (By promotion) |                -----------------------------------------------------------------------               |                                                                                      | Assistant Engineers                                                 Assistant Engineers (Degree) +  8 years’                                               (Diploma) + 10 years’ service                                                   service                                                            | Assistant Engineers Graduates and Diploma  Holders | --------------------------------------------------------------------------- |                                                                                         |                          50 per cent by                                    50 per cent by direct recruitment promotion                      |      --------------------------------------------     |                                                    |  25 per cent                               25 per cent Junior Engineers                      Junior Engineers (Degree) + 3                         (Diploma) + 8  years’ service               years’ service

                                                                     |             --------------------------------------------------------------------------------            |                                                                                                | Graduates in  Engg.                                                             Diploma hold ers (No prior experience                                            (with 2 years’ prescribed)                                                             experience)

             From a perusal of the rules regarding recruitment to the  post of Junior Engineers and, thereafter, their promotion to the  post of Assistant Engineers and subsequently to the post of  Executive Engineers in the service, it is clear that  entry point in   the service to the posts of Junior Engineers is by 100% direct  recruitment.  The educational qualification required is Diploma in  Civil Engineering with two years’ experience or Graduate in  Engineering as has been introduced since 1968.  Appointment by  direct recruitment to the post of Junior Engineer for  Diploma- holders in Civil Engineering, would be coupled with two years’  experience, whereas Graduates in Engineering are not required to  have any experience.  For promotion to the post of Assistant  Engineer, the rule prescribes that 50% of the posts will be filled up  by direct recruitment from the candidates having educational  qualification as Graduate in Civil Engineering, whereas the  remaining 50% of the posts are to be filled up by promotion from  the post of Junior Engineers. Under clause (a),  50% of the 50%  promotion quota, i.e. 25% of the total posts, have to be filled up by  promotion from the category of graduate Junior Engineers, i.e., the  persons who held the Degree at the entry point in Engineering with  three years of service, whereas under clause (b)  25% of the total  posts would be filled up by diploma-holders with eight years’  service.  The rule prescribes two sources for promotion from the  post of Junior Engineers \026 a graduate with three years’ service  experience and a diploma-holder with eight years’ service  experience.  A separate quota is, thus, prescribed for promotion of  Junior Engineers for degree and diploma-holders to that of higher  post of Assistant Engineer.  For further promotion from the post of  Assistant Engineer to the post of Executive Engineer, the  requirement of the rule is \026 for graduates, eight years’ service in  the grade; and, for diploma-holders, ten years’ service in the  grade.  This distinction between the graduate Engineers and  diploma-holders is maintained for promotion to the post of  Executive Engineer, although there is no separate quota  prescribed for graduates or diploma-holders, by prescribing  different experience for promotion on the basis of a person being a  graduate or a diploma-holder.                 In Roop Chand Adlakha and Others v. Delhi  Development Authority and Others, 1989 Supp. (1) SCC 116,  application of the rules governing same service conditions as  involved in the present case, was called in question in regard to  promotion of diploma-holder Junior Engineers and graduate Junior  Engineers, from the post of Assistant Engineer to the post of  Executive Engineer.  The diploma-holders in the cadre of Junior  Engineers and in the cadre of Assistant Engineers assailed the  constitutional validity of the rules prescribed in the matter of  difference in service experience between the graduates and  diploma-holders for promotion to the higher cadres.  They also  challenged the promotion of graduate Engineers to the higher  cadres adopting the relevant CPWD Rules prescribing three years’  and eight years’ experience for graduates and diploma-holders  respectively and the discrimination thus brought about between  them.  W. P. No. 2082 of 1984 pertained to the constitutional  validity of the analogous provisions in the rules adopted by  Resolution No.105 dated 16.6.1971.  The High Court prescribed

15

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 15 of 18  

differential service experience based on differences in educational  qualifications, violative of Articles 14 and 16 of the Constitution.   The High Court drew a distinction between the situation where the  diploma-holders were wholly excluded from eligibility for promotion  to the higher cadres and a situation where they were considered  eligible for promotion, however, were subjected to least  advantageous condition for such promotion.  The High Court  distinguished the decision of this Court in State of Jammu and  Kashmir  v.  Triloki Nath Khosa and Others, (1974) 1 SCC 19,  and said that "this was a case where diploma holders were found  completely ineligible for promotion to the higher post for lack of  essential educational qualification but the considerations may vary  if they are found eligible for promotion to the higher post but still  certain conditions are laid as distinct from degree holders before  they become eligible for promotion.  The question then would arise  whether such distinction can be justified and is based on any  rationality or not."                    The above-mentioned order of the High Court was  challenged in this Court  and after considering various authorities  this Court held in para 29 as under :-         "In Triloki Nath case Diploma Holders were not  considered eligible for promotion to the higher post.   Here, in the present case, the possession of a diploma,  by itself and without more, does not confer eligibility.   Diploma, for purposes of promotion, is not considered  equivalent to the degree.  This is the point of distinction in  the situations in the two cases.  If Diploma Holders \026 of  course on the justification of the job requirements and in  the interest of maintaining a certain quality of technical  expertise in the cadre \026 could validly be excluded from  the eligibility for promotion to the higher cadre, it does not  necessarily follow as an inevitable corollary that the  choice of the recruitment policy is limited to only two  choices, namely, either to consider them "eligible" or "not  eligible".  State, consistent with the requirements of the  promotional posts and in the interest of the efficiency of  the service, is not precluded from conferring eligibility on  Diploma Holders conditioning it by other requirements  which may, as here, include certain quantum of service  experience.  In the present case, eligibility determination  was made by a cumulative criterion of a certain  educational qualification plus a particular quantum of  service experience.  It cannot, in our opinion, be said, as  postulated by the High Court, that the choice of the State  was either to recognize Diploma Holders as "eligible" for  promotion or wholly exclude them as "not eligible".  If the  educational qualification by itself was recognized as  conferring eligibility for promotion, then the  superimposition of further conditions such as a particular  period of service, selectively, on the Diploma Holders  alone to their disadvantage might become discriminatory.   This does not prevent the State from formulating a policy  which prescribes as an essential part of the conditions for  the very eligibility that the candidate must have a  particular qualification plus a stipulated quantum of  service experience.  It is stated that on the basis of the  "Vaish Committee" report, the authorities considered the  infusion of higher academic and technical quality in the  personnel requirements in the relevant cadres of  Engineering Services necessary.  These are essentially  matters of policy.  Unless the provision is shown to be  arbitrary, capricious, or to bring about grossly unfair  results, judicial policy should be one of judicial restraint.   The prescriptions may be somewhat cumbersome or  produce some hardship in their application in some

16

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 16 of 18  

individual cases ; but they cannot be struck down as  unreasonable, capricious or arbitrary.  The High Court in  our opinion, was not justified in striking down the rules as  violative of Articles 14 and 16."

    Although the Court considered the case in the perspective of  Articles 14 and 16 of the Constitution of India, it is clear to us that  the classification was upheld between diploma-holder and  graduate Engineers on the basis of the requirements of the  promotional posts and in the interest of the efficiency of the  service.  While referring to experience required for promotion, the  Court has specifically said that eligibility determination was made  by a cumulative criterion of a certain educational qualification plus  a particular quantum of service experience.  Thus, as per the  Court, the requirement for promotion is the educational  qualification plus a particular quantum of service experience.  The  Court further observed that if the educational qualification by itself  is the only criterion conferring eligibility for promotion, then the  superimposition of further conditions such as a particular period of  service, selectively, on the diploma-holders alone, to their  disadvantage, might become discriminatory, but as it is the  eligibility criteria it cannot be held as a discrimination.   The Court  has made distinction between the service rendered as diploma- holder and graduate Engineer and thus has not found any  discrimination in different period of experience provided for  promotion for degree-holder and diploma-holder.  Degree and a  diploma with different period of service is held to be a valid  classification whereby a different period of service has been made  eligibility criteria along with educational qualification for promotion  to the higher post.         Taking into consideration the entire scheme of the relevant  rules, it is obvious that the diploma-holders would not be eligible  for promotion to the post of Assistant Engineer in their quota  unless they have eight years’ service, whereas the graduate  Engineers would be required to have three years’ service  experience apart from their degree.  If the effect and intent of the  rules were such to treat the diploma as equivalent to a degree for  the purpose of promotion to the higher post, then induction to the  cadre of Junior Engineers from two different channels would be  required to be considered similar, without subjecting the diploma- holders to any further requirement of having a further qualification  of two years’ service.  At the time of induction into the service to  the post of Junior Engineers, Degree in Engineering is a sufficient  qualification without there being any prior experience, whereas   diploma-holders should have two years’ experience apart from  their diploma for their induction in the service.  As per the service  rules, on the post of Assistant Engineer, 50% of total vacancies  would be filled up by direct recruitment, whereas for the promotion  specific quota is prescribed for a graduate Junior Engineer and a  diploma-holder Junior Engineer.  When the quota is prescribed  under the rules, the promotion of graduate Junior Engineers to the  higher post is restricted to 25% quota fixed.  So far as the diploma- holders are concerned, their promotion to the higher post is  confined to 25%.  As an eligibility criterion, a degree is further  qualified by three years’ service for the Junior Engineers, whereas  eight years’ service is required for the diploma-holders.  Degree  with three years’ service experience and diploma with eight years’  service experience itself indicates qualitative difference in the  service rendered as degree-holder Junior Engineer and diploma- holder Junior Engineer.  Three years’ service experience as a  graduate Junior Engineer and eight years’ service experience as a  diploma-holder Junior Engineer, which is the eligibility criteria for  promotion, is an indication of different quality of service rendered.   In the given case, can it be said that a diploma-holder who  acquired a degree during the tenure of his service, has gained

17

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 17 of 18  

experience as an Engineer just because he has acquired a  Degree in Engineering.  That would amount to say that the  experience gained by him in his service as a diploma-holder is  qualitatively the same as that of the experience of a graduate  Engineer.  The rule specifically made difference of service  rendered as a graduate Junior Engineer and a diploma-holder  Junior Engineer.  Degree-holder Engineer’s experience cannot be  substituted with diploma-holder’s experience.  The distinction  between the experience of degree-holders and  diploma-holders is  maintained under the rules in further promotion to the post of  Executive Engineer also, wherein there is no separate quota  assigned to degree-holders or to diploma-holders and the  promotion is to be made from the cadre of Assistant Engineers.   The rules provide for different service experience for degree- holders and diploma-holders.  Degree-holder Assistant Engineers  having eight years of service experience would be eligible for  promotion to the post of Executive Engineer, whereas diploma- holder Assistant Engineers would be required to have ten years’  service experience on the post of Assistant Engineer to become  eligible for promotion to the higher post.  This indicates that the  rule itself makes differentia in the qualifying service of eight years  for degree-holders and 10 years’ service experience for diploma- holders.  The rule itself makes qualitative difference in the service  rendered on the same post.  It is a clear indication of qualitative  difference of the service on the same post by a graduate Engineer  and a diploma-holder Engineer.  It appears to us that different  period of service attached to qualification as an essential criterion  for promotion is based on administrative interest in the service.   Different period of service experience for degree-holder Junior  Engineers and diploma-holder Junior Engineers for promotion to  the higher post is conducive to the post manned by the Engineers.   There can be no manner of doubt that higher technical knowledge  would give better thrust to administrative efficiency and quality  output.  To carry out technical specialized job more efficiently,  higher technical knowledge would be the requirement.  Higher  educational qualifications develop broader perspective and  therefore service rendered on the same post by more qualifying  person would be qualitatively different.              After having an overall consideration of the relevant  rules, we are of the view that the service experience required for  promotion from the post of Junior Engineer to the post of Assistant  Engineer by a degree-holder in the limited quota of degree-holder  Junior Engineers cannot be equated with the service rendered as  a diploma-holder nor can be substituted for service rendered as a  degree-holder.  When the claim is made from a fixed quota, the  condition necessary for becoming eligible for promotion has to be  complied with.  The 25% specific quota is fixed for degree-holder  Junior Engineers with the experience of three years.  Thus, on a  plain reading, the experience so required would be as a degree- holder Junior Engineer.  25% quota for promotion under the rule is  assigned to degree-holder Junior Engineers with three years’  experience, whereas for diploma-holder Junior Engineers eight  years’ experience is the requirement in their 25% quota.  Educational qualification along with number of years of service  was recognized as conferring eligibility for promotion in the  respective quota fixed for graduates and diploma-holders.  There  is watertight compartment for graduate Junior Engineers and  diploma-holder Junior Engineers.  They are entitled for promotion  in their respective quotas.  Neither a diploma-holder Junior  Engineer could claim promotion in the quota of degree-holders  because he has completed three years of service nor can a  degree-holder Junior Engineer make any claim for promotion  quota fixed for diploma-holder Junior Engineers.  Fixation of  different quota for promotion from different channels of degree- holders and diploma-holders itself indicates that service required

18

http://JUDIS.NIC.IN SUPREME COURT OF INDIA Page 18 of 18  

for promotion is an essential eligibility criterion along with degree  or diploma, which is service rendered as a degree-holder in the  present case.  The particular years of service being the cumulative  requirement with certain educational qualification providing for  promotional avenue within the specified quota, cannot be anything  but the service rendered as a degree-holder and not as a diploma- holder.   The service experience as an eligibility criterion cannot be  read to be any other thing because this quota is specifically made  for the degree-holder Junior Engineers.       As a necessary corollary, we are of the view that the  diploma-holder Junior Engineers who have obtained a Degree in  Engineering during the tenure of service, would be required to  complete three years’ service on the post after having obtained a  degree to become eligible for promotion to the higher post if they  claim the promotion in the channel of degree-holder Junior  Engineer, there being a quota fixed for graduate Junior Engineers  and diploma-holder Junior Engineers for promotion to the post of  Assistant Engineers.                For the above reasons, the appeals are allowed and the  impugned judgment of the High Court is set aside.  The writ  petitions shall now be decided by the Division Bench of the High  Court in accordance with law laid down herein.  The writ petitions  which were transferred to, and registered as Transferred Cases in,  this Court, shall also be sent back to the High Court for their  decision in accordance with law.
