[2026] 2 S.C.R. 62 : 2026 INSC 24
Abhay Kumar Patel & Ors. 
v. 
State of Bihar & Ors.
(Civil Appeal No. 54 of 2026)
06 January 2026
[J.K. Maheshwari* and Vijay Bishnoi, JJ.]
Issue for Consideration
Whether the Bihar Engineering Service Class-II Recruitment 
(Amendment) Rules, 2022 can be made applicable to the 2019 
Advertisements after the written examination has been conducted 
and the provisional merit list has been published.
Headnotes†
Service Law – Appointment/Recruitment/Selection – Bihar 
Engineering Services Class - II Recruitment Rules, 2019 – The 
dispute in the present case is with respect to the retrospective 
application of an amendment to the Bihar Engineering 
Services Class – II Recruitment Rules, 2019, specifically the 
introduction of r.8(5), whereby weightage for prior contractual 
work experience was introduced after the selection process 
comprising the written examination had initiated and the 
provisional merit list had already been published – The 
appellants had preferred the writ petition challenging the 
retrospective application of the Bihar Engineering Service 
Class-II Recruitment (Amendment) Rules, 2022 – The High 
Court dismissed the writ petition – Correctness:
Held: In the present case, the “game” had not only commenced 
but was at its fag end – The written examinations were held in 
March 2022 – The results were declared in June/July 2022 – The 
candidates were called for document verification – At this stage, 
the selection process had proceeded significantly, and would 
have concluded with the filling up of vacancies – The issuance of 
the 2022 Amendment Rules, introducing r.8(5) with retrospective 
effect from 06.03.2019, attempts to rewrite the rules of the game 
which has already begun – By reducing the 25 weightage of the 
written examination to 75 marks and introducing 25 marks for

contractual experience, the State has fundamentally altered the 
basis of selection and changed the ‘eligibility criteria for being 
placed in the merit list’ which is not permissible – While the State 
undoubtedly has the power to amend rules under the proviso to 
Art.309 of the Constitution of India, this power is not unbridled – 
The power of retrospective legislation cannot be exercised to take 
away vested rights or to arbitrarily disrupt a selection process that 
has already resulted in the identification of successful candidates 
by publication of a provisional merit list – The distinction drawn 
by the respondents regarding the “provisional” nature of the merit 
list is untenable – The list was provisional subject to verification of 
documents, not subject to a fundamental change in the criteria for 
placement in the merit list itself – The retrospective application of 
r.8(5) creates an anomaly where candidates who competed under 
one set of rules are now being judged by another, ex post facto – 
This directly impacts the appellants, who may be pushed down 
the merit list or ousted entirely by candidates who score lower in 
the written exam but gain the newly introduced additional marks 
for contractual service – The finding of the High Court that the 
amendment was merely a policy decision and could be applied 
retrospectively to the selection process in vogue is completely 
erroneous – The retrospective application of r.8(5) of the 2019 
Rules, as introduced by the 2022 Amendment Rules, cannot be 
sustained insofar as the recruitment process initiated vide the 2019 
Advertisements following the 2019 Rules prevalent at the said point 
of time – Impugned judgment and order of the High Court is set 
aside. [Paras 34-38, 41, 42, 44]
