State may validly amend service rules to introduce additional promotion qualifications and staff redeployment for administrative exigencies.

The petitioners, Post Graduate Teachers (PGT) in various Government-aided private schools in Tripura, challenged the constitutionality of the Tripura Grant-in-Aid (Government Aided Schools) 1st Amendment Rules, 2022.

Specifically, they contested Rule 5, which introduced new eligibility criteria for promotion to Assistant Headmaster (requiring 50% marks in Master’s degree and B.Ed.).

They also contested Rule 13, which permitted the "redeployment" (transfer) of staff from one aided school to another based on student enrollment/rationalization.

Petitioners argued that since their original appointment orders did not stipulate transfers and their promotional prospects were now hampered by new academic requirements, the rules were arbitrary and retrospectively prejudicial.

The Court primarily applied the principle that the State has the exclusive policy discretion to determine service conditions, cadres, and promotional criteria under Article 14 and 16 of the Constitution.

It relied on *P.U. Joshi v. Accountant General*, which established that employees have no vested right to have service rules remain unaltered forever.

Further, it applied *State of Himachal Pradesh v. Raj Kumar*, holding that the "rule in force" at the time of consideration for promotion applies, and there is no universal rule that vacancies must be filled based on old laws.

The Court also noted compliance with NCTE guidelines (2010) regarding minimum qualifications.

The Court reasoned that the State is competent to amend rules to ensure quality education as per the National Education Policy 2020 and NCTE standards.

It found that the requirement of 50% marks for promotion was a valid policy choice and not arbitrary.

Regarding Rule 13, the Court held that "redeployment" was a necessary rationalization measure to protect the jobs of teachers in schools with low enrollment; without it, staff in non-functional schools might face termination.

Furthermore, Rule 13(iii) protected the seniority of such teachers by counting service from their original school.

However, the Court identified a lack of *bona fides* in the State's memo dated 31.08.2024, which stayed the transfer of three specific individuals for 16 months under the guise of "temporary" medical grounds while enforcing transfers for the petitioners.

Consequently, WP(C) No. 631/2024 and WP(C) No. 503/2025 were dismissed, and the promotion of the respondent in the latter was upheld.

However, WP(C) No. 629/2024 and WP(C) No. 630/2024 were partly allowed; the Court quashed the memo dated 31.08.2024 as discriminatory and directed the State to immediately implement the redeployment of the three favored individuals to ensure parity.
