Abhay Kumar Patel & Ors. v. The State of Bihar & Ors.
Background
After a written exam and provisional merit list were already finalized, Bihar amended recruitment rules to add retrospective bonus marks for prior work experience, disadvantaging candidates who had already competed and topped the list under the original rules.
Decision Breakdown
The Supreme Court applied the principle that "the rules of the game cannot be changed once the game has begun," holding the retrospective amendment violated Articles 14 and 16, and ordered appointments finalized strictly under the original 2019 rules.
Lesson Learnt
Once a government recruitment process reaches an advanced stage, the rules cannot be retrospectively changed to disadvantage candidates who already competed under the original terms.
