A
In 1978 certain promotions were made to the category or Assistant
Executive Engineers by applying the ratio or 3:1 between the graduate-en-
~
gineers (Assistant Engineers) and the diploma-holder-engineers (Junior
Engineers).
The respondents-Junior Engineers challenged the promotions in
B writ petitions in the High Court, which was dismissed by a Single Judge.
On appeal, a Division Bench of the High Court quashed the promotions holding that as the Madras Corporation Engineering SerVice Rules,
1969 did not provide for any ratio, the Corporation could not prescribe
C the ratio or 3:1 by a mere resolution or by an executive order.
D
The Special Leave Petition prererred against the "judgment or the
Division Bench or the High Court was dismissed by this Court on
25.1.1990.
The State Goverumeat thereafter amended the 1969 Rules in 1990
providing for the ratio or 3:1 between the degree-holders and the diploma·
holders in the matter or promotion to the posts or the Assistant Executive
Engineers. The 1990 Amendment Rules also provided that a Junior En·
gineer (diploma-holder) who acquired an engineering degree or its
E equivalent during his service would be eligible for appointment as Assis·
tant Executive Engineer, ir he puts in three years or service in the Corporation Engineering Subordinate Service after obtaining the degree.
F
G
The diploma-holders questioned the validity or the 1990 Amendment
Rules, in writ petitions before the High Court.
The Single Judge dismissed the writ petitions and upheld the validity
or the 3:1 ratio. On appeal, the Division Bench quashed the amendment
introducing the ratio or 3:1, against which the present appeal was filed by
the graduate Engineers.
The appellants contended that the Assistant Engineers and the
Junior Engineers constituted different categories though performing
similar functions and discharging similar responsibilities; that their pay·
scales were different; that the Statutory Rules of 1969 made a distinction,
between the two categories inasmuch as while only Ove years' qualifying
H service was prescribed for the Assistant Engineers (graduates), ten years
MURUGESAN v. STATE OF TAMIL NADU
407
was prescribed for the Juuior Engineers (diploma-holders); that in such A
a situation imposing of an additional restriction upon the promotional
chances of Junior Engineers by the 1990 Amendment Rules was neither
incompetent nor discriminatory; that Section 87 of the Madras City
Municipal Corporation Act was not mandatory but only directory •.
The respondents-diploma-holders submitted that in the category of B
Supervisors graduates were appointed by direct recruitment and diplomabolders by promotion from the category of Overseers; that the Assistant
Engineers as well as Junior Engineers performed identical functions and
discharged identical responsibilities; that they were inter-transferable;
that In such a situation prescription of a quota between them for promoC
tion to the higher category was discriminative and was violative of Articles
14 and 16 of the Constitution; that once the diploma-holders were required
to put in ten years' service as against live years' service in the case of the
graduates, in the category of Supervisors for becoming eligible for promotion as Assistant Execntive Engineers, the eligible graduates and the
eligible diploma-holders became equals in all respects and there should D
not be any distinction thereafter for the purpose of promotion; that at any
rates In view of the provisions in Section 87 of the Madras City Municipal
Corporation Act, the vacancies which arose prior to the coming into force
of the 1990 Amendment Rules should be filled up in accordance with the
unamended Rules, i.e. without reference to the quota.
E
Allowing the appeal, this Court,
HELD : 1.01. It is held by the constitution Bench in Tri/old Nath
Khosa that a distinction made on the basis of academic qualification for
the purpose of promotion to higher category is not violative of Articles 14 F
and 16. Jn the said case, a rule barring the non-graduate-engineers from
promotion to the category of executive engineers was upheld. If the
diploma-holders can be barred altogether from promotion as held in
Tri/oki Nath Khosa, it is difficult to appreciate how and why is the rule
making authority precluded from restricting the promoti\)n. The rule G
making authority may be of the opinion, having regard to the efficiency of
the administration and other relevant circumstances that while it is not
necessary to bar the diploma-holders from promotion altogether, their ·
chances of promotion should be restricted. [416E, 4170]
1.02. There would be no justification in principle for holding that the H
408
SUPREME COURT REPORTS
(1993) 1 S.C.R.
A rule-making authority has only two options namely either to bar the
diploma-holders altogether from prometion or to allow them equal oppor·
B
tunity with the graduate engineers in the matter of promotion. It must be
~
remembered that the power of rule-making under the proviso to Article
309 has been held to be legislative in character. [419C]
1.03. If so, the test is whether such a restrictive view is permissible
vis-a-vis a legislature. If not, it is equally impermissible in the case of the
rule-making authority under the proviso to Article 309. The only test that
such a rule has to pass is that of Articles 14 and 16. [ 4190)
C
1.04. Since 1969 the graduate supervisors and non-graduate Supervisors Mre treated differently in the matter of pay, designation and in the
matter of promotion, though they were discharging identical functions and
duties. It is thus clear that though they belonged to one class Ibey represented two different categories, while it is true, they performed similar
duties and discharged similar responsibilities. [419G)
D
A
E
1.05. It cannot be said that it is not permissible to the rule-making
authority, if it thinks it necessary in the interests of administration to limit
the promotional chances of non-graduates to one out of four vacancies, on
the basis of academic qualifications. (4208)
1.06. The distinction was also in the matter of promotion and not
for any other purpose. If that distinction is not discrimination, it is
difficnlt to see bow and why another distinction now created (quota rule)
is discriminatory. [ 4220)

2.01. Section 87 of the Madras City Municipal Corporation Act does
indicate and manifest the concern of the Legislature that the vacancies
occurring in the Corporation Service should not be kept unfilled for a
period of more than three months. Sub-section (3) which provides for the
consequence of default on the part of the council to abide by sub-section
(1) emphasises the concern of the Legislature. So also does sub-section
(2). Sub-section (4) says that if there is going to be any delay or ifa suitable
or qualified person is not available, the council may appoint a person on
temporary basis. [424H, 425A)

months prior to the coming into force of the impugned amendment (introducing the quota of 3:1 as between degree:holders and diploma-holders ) E
F
and shall work out the vacancies which would have gone to the diplomaholders if unamended Rules had been followed. The Corporation shall also
ascertain which of the diploma-holders would have been promoted in those
vacancies. Such diploma-holders will be promoted in the existing and future
vacancies. Until these diploma-holders are so promoted to the category of
Assistant Executive Engineers, no degree-holders shall be promoted. After
these diploma-holders are so promoted, it is obvious, the amended Rules
shall be applied and followed. As and when a diploma-holder is promoted in
pursuance of this direction, his promotion shall be given effect to from the
date he ought to have been promoted. Such diploma-holder promotees shall G
be entitled to the benefit of seniority and pay-fixation Rowing from such
retrospective promotions, but they shall not be entitled to th,e.arrears of
'dilTerence in salary for the period they have not actually worked as Assistant

The Judgment of the Court was delivered by
B.P. JEEVAN REDDY, J. Heard the Counsel for the parties. Leave
granted.
The dispute is between the degree holders and the diploma holders
in the engineering service under the Madras Municipal Corporation.
The Corporation of Madras is governed by the Madras City
Municipal Corporation Act, 1919. It employs a good number of engineers
F in connection with the discharge of its duties. Till 1%5, there was only one
category of supervisors. Recruitment to this category was by direct recruitment of graduate engineers as well as by promotion from the lower
category 9f overseers. Diploma holders were not eligible for direct appointment as supervisors; they were first appointed to the category of overseers
and then promoted as supervisors. The category above the supervisors was
G that of assistant engineers. Supervisors, whether directly recruited
(graduates) or promotees (diploma-holders) were required to put in 20
years' service in the category of supervisors io become eligible for promotion to the category of assistant engineers. No distinction was made as
between the degree holders (graduates) and diploma-holders in the matter
H of promotion or in the matter of eligibility criteria.
MURUGESAN i·. STA~OF TAMIL NADU (REDDY, J.]
411
In the year 1965, say the a pellants (who are all graduate engineers), A
the Corporation resolved (on 7 .. 65) to follow the rule in vogue in State
Government service and apply 'the ratio of 3:1 between graduates and
diploma-holders in the matter of promotion to the category of assistant
engineers. The respondents who are all diploma-holders, deny that any
such resolution was passed. According to them it was only a recommendaB
tion of the Ad-hoc Committee constituted by the Corporation and that the
said recommendation was never accepted as such by the Corporation. The
respondents rely upon the Division Bench judgment dated 21.12.89 in writ
appeal No. 990 of 1984 etc. holding that no such ratio was actually enforced
in the Corporation Engineering Service. Be that as it may, some time prior
to 1969, the Act was amended empowering the Government to frame rules C
regulating the recruitment and conditions of service of the employees of
the Corporation. In exercise of the said power, the Government of Tamil
Nadu framed rules called Madras Corporation Engineering Service Rules
(contained in G.0.M.S. No. 31 RD-LA dated 7.1.69). These rules applied
only to class lA, lB and class II of engineering services under the CarD
poration and riot to other posts. The post of assistant engineer was in
category III in class-II. Recruitment to this category was by (a) direct
recruitment (b) promotion from the category of supervisors and (c) by
appointment on deputation from the Government department. So far as
promotion is concerned, a distinction was made as between degree-holders
and diploma-holders. The graduate supervisors were required to put in a E
minimum of five years service in the category of supervisors for becoming
eligible for promotion, whereas the diploma-holder-supervisors were required to put in a minimum service of ten years as supervisors to become
eligible for such promotion. At about this time, a practice developed
whereunder graduate-supervisors were referred to as Junior engineers. The
diploma-holders-supervisors (who are necessarily promotees in the
category of supervisors) continued to be referred to as supervisors.
F
In the year 1978 the Government ofTan;til N.adu altered the designations of the categori~ relevant before us by G.O.M.S. No. 954 dated
2.6.1978. Para-2 of theiG~O. stated that the diploma-holder-supervisors G
shall be designated a5 junior engineers while the degree-holders-supervisors (who had come to be known as junior engineers meanwhile) would
be desi$'11lted as assistant engineers. Consequently the erstwhile post of
assistant engineer was re-designated as assistant executive engineer. By
G.O.M.S. No. 907 dated 20.5.1981, this change. in designation was given H
4U
SUPREME COURJ REPORTS
(1993) 1 S.C.R.
A effect to and incorporated in the Statutory Rules issued in 1969 (Madras
Corporation Engineering Service Rules).
The recruitment and conditions of service of assistant engineers and
juniors (formerly known together as Supervisors) were governed by the
B by-laws made by the Corporation. In the matter of pay scales too, a
distinction was being maintained between graduates and diploma-holders
even when they were in the same category of Supervisors. The pay scale
admissible to the category of supervisors was 325-650 but the graduates
were given a higher start-their initial pay was fixed at 400. No such
treatment was given to the diploma-holders. According to the appellants
C there was yet another distinction from 1972 onwards; the pay-scales
prescribed for the graduate engineers and dip!Oma-holder-engineers were
different as per the particulars mentioned in para 33 of the S.L.P. They
point out that in the counter filed to the Special Leave Petition, the
respondents have not denied the said averment; they merely stated in para
D 20 of their counter that the "allegations in paragraphs 33 to 36 are of no
avail to the petitioner."
Whether in pursuance of the Resolution of 1965 or otherwise, certain
promotions were made to the category of assistant executive engineers, in
the year 1978, applying the ratio of 3:1 as between graduate-engineers and
E diploma-holder-engineers. We may refer to these two categories
hereinafter as assistant engineers and junior engineers, since that was the
designation given to them by G.O.M.S. No. 954 dated 2.6.1978. The said
promotions were questioned by diploma-holders in a batch of writ petitions
(2810 of 1978 etc.) in the Madras High Court. It was dismissed by a learned
F Single Judge. On appeal, however, a Division Bench of that court held
Gudgment dated 21.12.1989 in Writ Appeal No. 990 of 1984 etc.) that
inasmuch as the Statutory Rules framed in 1969 did not provide for any
such ratio, it is not open to the Corporation to prescribe such a ratio by a
mere resolution or by an executive order. Accordingly, the Division Bench
G quashed the said promotions. A Special leave petition preferred against
the said judgment in this Court was dismissed on 25.1.1990. It is then that
the Government of Tamil Nadu stepped in and amended the 1969 Rules
providing for the said ratio of 3:1 by way ofG.O.M.S. No. 138 (Municipal
Administration and Water Supply) dated 9th February, 1990. So far as
relevant herein, the said G.O. prescribed the "ratio of 3:1 between the
H degree holders and diploma holders" in the matter of promotion to the
...... \

MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.]

assistant executive engineers. It was further provided that a junior engineer A
{diploma-holder) who acquired an engineering degree or its equivalent
during his service as junior engineer will be eligible for appointment as
assistant executive engineer if he puts in three years of service in the
Corporation Engineering Subordinate Service after obtaining the engineering degree or its equivalept. The result of this amendment was that a B
two-fold distinction came to be made between graduates and diplomaholders in the matter of promotion to the post of assistant executive
engineers. In addition to the hitherto existing distinction in the matter of
length of qualifying period of service {10 years for diploma-holders/junior
engineers as against 5 years for degree-holders/assistant engineers), the
new restriction imposed by the said amendment was that the diploma C
holders/junior engineers were restricted to only one out of four posts of
assistant executive engineers; the remaining three were ·reserved for
graduates/assistant engineers. (Of course, according to the appellant such
a ratio was in vogue as a matter of fact since 1965. the respondents deny
this assertion. Be that as it may, the ratio - or quota, as it may be called - D
was statutorily imposed by the said amendment.
The validity of the 1990 amendments, in particular the introduction
of ratio of 3:1, was questioned by diploma-holders in the Madras High
Court in a batch of Writ Petitions being Writ Petition 2943 of 1990 etc. A
learned Single Judge dismissed the batch by his Judgment and Order dated E
21.3.1991, upholding the validity of the said ratio. On appeal, a Division
Bench took a contrary view and quashed the amendment introducing the
ratio of 3:1. In this appeal, the correctness of the view taken by the Division
Bench is called in question.
F
Mr. M.K Ramamurthy, learned counsel for the appellants' submitted
that classification on the basis of academic qualifications is a well accepted
basis for the purpose of promotion and that the Division Bench of the
Madras High Court was in error in holding otherwise. He submitted that
assistant engineers and junior engineers constituted different categories
though performing similar functions and discharging similar responG
sibilities. Their pay-scales were different-at any rate from 1972. Even
earlier, the pay fJXation formula was different in the case of graduates. Even
the Statutory Rules of 1969 made a distinction between the two categories
inasmuch as while only five years' qualifying service was prescribed for
graduates, ten years' qualifying service was prescribed for diploma-holders. H
414
SUPREME COURT REPORTS
(1993) 1 S.C.R.
A In sui;h a situation imposing an additional restriction upon the promotional
chances of diploma hold~rs by the impugned amendment is neither incompetent nor can it be characterised as discriminatory. He submitted that
right from 1972 onward, a clear distinction was being observed between
the graduates and diploma-holders and that the impugned amendment is
B but another step in the same process.
On the other hand the learned counsel for the respondents-diplomaholders submitted that wheiher graduates or diploma-holders, they were
all in the category of supervisors till the year 1981. There was only one
category of supervisors to which graduates were appointed by direct
C recruitment and diploma-holders by promotion from the lower category of
overseers. They performed identical functions and discharged identical
responsibilities. They were inter-transferable. On some occasions,
graduates (assistant engineers) were posted to assist a diploma holder
Gunior engineer) in discharging certain duties. Even after 1978 when the
D
graduates-supervisors werti'designated as assistant engineers and diploma,
holders-supervisors were designated as junior engineers, the same situation
continued. In such a situation prescription of a quota as between them for
promotion to the higher category is discriminatory and is violative of
Articles 14 and 16 of the Constitution. Learned coun~el submitted that in
any event once the diploma-holders were required to put in ten years'
E service (as against five years' service in the case of graduates) in the
category of supervisors for becoming eligible for promotion as assistant
executive engineers, the eligible graduates and the eligible diploma-holders
became equals in all respects. No distinction is permissible thereafter in
the matter of and for the purpose of promotion. Creating such a distinction,
F
imposing a disability upon the diploma-holders, is not only unjust and
inequitable, it is also a clear case of hostile discrimination. Lastly and
alternatively counsel submitted that the vacancies which arose prior to the
coming into the force of the impugned amendment, at any rate, should be
filled up in accordance with the unamended Rules. It is pointed out that
the impugned amendment is only prospective in operation. Section 87 of
G the Act is relied upon in this behalf.
It is true that theory of classification should not be carried too far
lest it may subvert, perhaps submerge, the precious guarantee of equality,
as pointed out by Chandrachud, J. in State of Jammu & Kashmir v. Triloki
H
Nath Khosa, [1974) 1 SCR 771. Minute and microcosmic classification
MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.j
415
should not be permitted nor should the Court countenance "mini classificaA
tions based on micro distinctions", as pointed out by Krishna Iyer, J. in the
same case. Looked at from this broad angle, it may appear there is some
force in what the respondents contend viz., that. once the graduate-engineers and diploma-holder-engineers constitute one class, perform same
.duties and discharge same responsibilities, placing a restriction on the B
diploma holders alone (limiting their chances of promotion to one out of
four promotions, as has been done by the impugned Amendment) is not
justified but this may be a too simplistic way of looking at the issue. We
cannot fail to take note of the fact that right from 1974 i.e., since the
decision of the Constitutions Bench in Triloki Nath Kilosa this Court has
been holding uniformily that even where direct recruits and promotees are C
integrated into a common class, they could for purposes of promotion to
the higher .cadre be classified on the basis of educational qualifications.
In the Kashmir Engineering Service, the post of assistant engineer
could be filled both by direct recruitment as well as by promotion. There D
were degree-holders and also diploma-holders in the category. By the
Kashmir Civil Services (Revised Pay) Rules, 1968 it was provided that a
diploma-holder-assistant engineer shall not cross the stage of Rs. 610 in
the scale of Rs. 300-30-540-EB-35-610-EB-35-750, which was the scale
applicable to assistant engineers. In 1970, Jammu and Kashmir Engineering
(Gazetted) Service Recruitment Rules, 1970 were issued providing that the
post of executive engineer (the next higher post) shall be filled only by
promotion from among the assistant engineers, who possessed a bachelor's
degree in engineering or its equivalent qualification provided they have put
in seven years'· '·service in the assistant engineer's category .. Assistant engineers who were not degree-holders were thus barred from promotion to
the category of executive engineers. Both the Rules, namely 1968 Pay Rules
and 1970 Recruitment Rules were questioned by diploma-holders in the J
E
F
& K High Court. Though a learned Single Judge dismissed the writ
petition, his judgment was reversed in appeal by the Division Bench. The
Division Bench was of the opinion that where the employees were grouped
together and integrated into one unit without reference to their qualifica- G
tions, they form a single class in spite of initial disparity in the matter of
their educational qualifications and that no discrimination is permissible to
be made between them on the basis of such qualifications. On appeal this
Court reversed the Judgment of the Division Bench. Two judgments were
delivered, one by Chandrachud J. on behalf of himself A.N. Ray, C.J. and H

A D.G. Palekar, and the other by Krishna Iyer, J. for himself and Bhagwati
J. Chandrachud J. while affirming the principle that a classification niust
be truely founded on substantial differences which distinguished persons
grouped together from those left out of the group and that such differential
attributes must bear a just and ·rational relation to the object sought to be

achieved, stated the scope of the Judicial scrutiny in such matters in the
following words :
"Judicial scrutiny can therefore extend only to the consideration whether the classification rests on a reasonable
basis whether it bears nexus with the object in view. It
cannot extend to embarking upon a nice or mathematical
evaluation of the basis of classification, for were such an
inquiry permissible it would be open to the courts to
substitute their own judgment for that of the legislature
or the rule-making authority on the need to classify or the
desirability of achieving a particular object."
The learned Judge held that judged from the above stand-point it
was impossible to accept the proposition that the classification of Assistant
Engineers into Degree-Holders and Diploma-Holders rests on any unreal
or unreasonable basis. They accepted the plea that the said classification
E was brought about with a view to achieving administrative efficiency in the
Engineering services. The higher academic qualifications, the learned
Judge held, is atleast presumptive evidence of a higher mental equipment.
The learned Judge said "what is relevant is that the object to be achieved
here is not a mere pretence for an indiscriminate imposition of inequalities
F
and the classification cannot be characterized as arbitrary or absurd. That
is the farthest that judicial scrutiny can extend." The learned Judge referred
to the earlier decision of this Court in State of Mysore & Anr. v. P. Narasing
Rao, (1968] 1SCR407 and the Union of India v. Dr. (Mrs.) S.B. Kohli, AIR
1973 SC 811 to demonstrate that a distinction made on the basis of
G academic qualifications was always upheld by this Court. Indeed, in the
latter case, the relevant rule required that a professor of orthopaedics must
have a post-graduate degree in the particular speciality. It was upheld as
a relevant requirement, The learned Judge then explained the decision in
Roshan Lal Tandon v. Union of India (upon which substantial reliance was
placed by the respondents in that case) as an authority certainly for the
H proposition that "no discrimination could be made between promotees and
-{'
MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.]

direct recruits by reference to the source from which they were drawn" but A
that it does not bar a classification based upon academic qualifications. In
the words of Chandarchud. J. Roshanlal Tandon's case is thus no authority
for the proposition that if direct recruits and promotees are integrated into
one class, they cannot be classified for purposes of promotion on a basis
other than the one that they were drawn from different sources." Having B
thus distinguished Roshan/a/ Tandon's case and Menyn v. Collector of
Bombay, AIR 1967 S.C. 52, the learned Judge concluded :
"We are therefore of the opinion that though persons
appointed directly and by.promotion were intregrated into
a common class for Assistant Engineers, they could, for
purposes of promotion to the cadre of Executive Engineers, be classified on the basis of educational qualifications. The rule providing that graduates shall be eligible
for such promotion to the exclusion of diploma-holders
does not violate articles 14 and 16 of the Constitution and
must be upheld."
This decision clearly supports the appellants' contention and goes to sustain
the validity of the impugned amendment. If the diploma-holders can be
barred altogether from promotion, it is difficult to appreciate how and why
is the rule making authority preciuded from restricting the promotion. The
Rule making authority may be of the opinion, having regard to the efficiency of the administration and other relevant circumstances that while it is
not necessary to bar the diploma-holders from promotion altogether, their
chances of promotion should be restricted. On principles, there is no basis
for the contention that only two options are open to a rule making
authority-either bar the diploma-holders altogether or allow them unrestricted promotion on par with the graduates. This aspect has been
emphasised by Venkatachaliah J. in Roop Chand Adlakha and Ors. v.
D.DA. and Ors., [1988] 3 Supp. SCR 253 in the following words.
"If Diploma-Holders - of course on the justification of the
job-requirements and in the interest of maintaining a
certain quality of technical expertise in the cadre - could
validily 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 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 cumulativecriterion 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 recognise Diploma'
Holders as "eligible" for promotion or wholly exclude them
as
11not-eligible'.'·
Counsel for the respondents however placed strong reliance upon
D certain observations made by Bhagwati, J. in Mohammad Shujat Ali & Ors.
etc. v. Union of India and Ors. etc., (1975) 1 SCR 449. After referring to
the facts of, and the principles enunciated in, T.N. Khosa the learned Judge
made the following observations:
E
F
G
H
"But where graduates and non-graduates are both
regarded as fit and, therefore, eligible for promotion, it is
difficult to see how, consistently with the claim for equal
opportunity, any differentiation can be made between
them by laying down a quota of promotion for each and
giving preferential treatment to graduates over nongraduates in the matter of fixation of such quota. The
result of fixation of quota of promotion for each of the
two categories of Supervisors, would be that when a vacancy arises in the post of Assistant Engineer, which, according to the quota is reserved for graduate Supervisors, a
non-graduate supervisor cannot be promoted to that
vacancy, even if he is senior to all other graduate Supervisors and more suitable than they. His opportunity for
promotion would be limited only to vacancies available for
non-graduate Supervisors. That would clearly amount to
denial of equal opportunity to him."
MURUGESAN v. STATE OF TAMIL NADU [REDDY, J.]

..).
On the basis of the above observations it is argued that once the A
diploma-holders are also held eligible for promotion, it is not permissible
for the rule-making authority to make any distinction between graduates
and diploma-holders. We cannot agree. As a matter of fact; this court in
Shujat Ali case upheld the validity of the Andhra Pradesh rule which made
a distinction between the graduate supervisors and non-graduate superB
visors in the ·matter of promotion to the higher categories on the ground
~
that in the erstwhile States of Andhra and Hyderabad, graduate supervisors
were always treated as distinct and separate from the non-graduate supervisors, their pay scales were different; they were never really integrated into
one class and graduate supervisors were called Junior Engineers. Accordingly, it was held that reducing the chances of promotion of non-graduate c
supervisors vis-a-vis graduate supervisors was not discriminatory. (As we
shall presently point out, the factual situation in Madras Corporation
Engineering service is similar). The observations quoted above cannot be
~ read in isolation nor can they be read as running counter to the ratio of
T.N. Khosa. Both decisions were rendered by Constitution Benches. In any
event, the facts and circumstances of the case before us are akin to those D
in Shujat Ali. Secondly as explained hereinbefore there would be no
justification in principle for holding that the rule-making authority has only
two options namely either to bar the diploma-holders altogether from
,>-..
promotion or to allow them equal opportunity with the graduate engineers
in the matter of promotion. It must be remembered that the power of
rule-making under the proviso to Article 309 bas been held to be legislative E
in character. Vadera - A.I.R. 1%9 S.C. 118. If so, the test is whether such
a restrictive view is permissible vis-a-vis legislature. If not, it is equally
impermissible in the case of the rule-making authority under the proviso
to Article 309. The only test that such a rule has to pass is that of Articles
14 and 16 -
and to that aspect we may turn now.

The facts of this case, narrated hereinbefore, clearly disclose that
long prior to the impugned amendment, a clear distinction was being
maintained between these two categories. The 1969 Rules, as originally
issued, prescribed a five years' qualifying service for graduate engineers G
while prescribing ten years' qualifying service for diploma holders, though
~
earlier it was twenty years for both uniformly. No one ever questioned it.
The graduates were designated as Assistant Engineers while Supervisors
were designated as junio; engineers in the year 1978. This distinctive
designations were recognised by and incorporated into the Statutory Rules
(1%9 Rules) in the year 1981. No grievance was made on that count. Even H

A when both of them were in the same pay scale, the graduates were being
given a higher start at Rs. 400 straightway, while no such benefit was given
to a promotee. Further, from 1972 onwards, it appears, their very payscales were different. It is thus clear that though they belonged to one class
they represented two different categories, while it is true, they performed
B similar duties and discharged similar responsibilities. It is asserte(j by the
Respondent's counsel that there is also a common seniority list but this fact
is denied by the appellant. According to them, there were two separate .
seniority lists till 1979 and that when in 1979 a single seniority list was
prepared, it was objected to by the graduates. Be that as it ·may, the
question still remains whether it is not permissible to the rule-making
C authority, if it thinks it necessary in the interests of administration to limit
the promotional chance::i of non-graduate to one out or four vacancies, on
the basis of academic qualifications. In the light of the Constitution Bench
decision in Triloki Nath Khosa, we cannot say that it is not permissible.

In Shamkant Narayan Deshpande v, Maharashtra Industrial Development Corporation & Ors.., 1992 (2) Scale 857 a Bench consisting of P .B.
Sawant and G.N. Ray, JJ. took the same view as we do in this case. We
also agree with the basis upon which the learned Judges di.stinguished the
decision in H.C. Sharma and .Ors. v. Municipal Corporation of Delhi and
Others, [1983] 3 SCR 372.
The learned counsel for respondents relied upon the decision in
Punjab State Electricity Board and Anr. v. Ravinder Kumar Sharma and Ors., .
[1987] 1 SCR 72, a decision rendered by a Bench ·comprising A.P. Sen and
B.C. Ray, JJ .. the category of line-men in the service of the Punjab State
F
Electricity Board comprised both diploma-holders and others who may be
referred to as non-diploma-holders. They censtituted one single category
having a common seniority list. By means of the Rules issued under the
proviso to Article 309, a quota was prescribed for diploma-holders, :he
result of which was that diploma-holders who were far junior to the
non··diploma-holders we~e promoted ignoring the non-diploma-holders.
G The rule was held to be bad by the learned Subordinate Judge, Patiala. On
appeal, the Additional District Judge, Pa ti ala affirmed the judgment. It was
affirmed by the High Court as well. The matter was brought to this Court.
This court affirmed the judgment of the High Court. A persual of the
judgment shows that the attention of the Bench was not diawn either to
H T.N. Khosa or to other decisions. Reference was made only to the obser-

vations in Shujat Ali quoted hereinbefore and it was held that the distincA
tion· made between the diploma-holders and non-diploma-holders was
discriminatory and bad.
