The proposed Writ Petition under Article 226 of the Constitution of India before the Madras High Court is not only feasible but carries a exceptionally high probability of success.
The action of the Principal Accountant General (AG), Chennai, in returning/objecting to the pension proposal, along with the subsequent coercion by the Block Educational Officer (BEO) to accept a reduced Grade Pay of ₹4,700, is legally unsustainable, arbitrary, and directly contrary to established statutory rules and binding High Court precedents.
The client served and retired in the cadre of Primary School Headmaster without taking any promotion. Therefore, applying this restriction letter to reduce her legitimate Selection Grade pay is a misapplication of administrative instructions.
Under G.O. Ms. No. 23, Finance (Pay Cell) Department, dated 12.01.2011, read with Government Letter No. 63305/Pay Cell/2010-1 dated 05.01.2012, Primary School Headmasters who were awarded Selection Grade between 01.01.2006 and 31.05.2009 are legally entitled to the revised Selection Grade Pay of ₹5,400 (Pay Band 2: ₹9,300–34,800 + GP 5400). Having attained Selection Grade on 07.07.2008 (falling precisely within the window of 01.01.2006 to 31.05.2009), her entitlement is statutorily protected.
Under the Tamil Nadu Pension Rules, 1978, pension and DCRG must be calculated strictly on the basis of the Last Drawn Pay (Emoluments).
The Accountant General has no unilateral authority to re-fix or reduce pay that was granted nearly two decades ago (2008) and continuously drawn until superannuation without any misrepresentation or fraud by the employee.
The BEO may press the client to sign an undertaking agreeing to ₹4,700 Grade Pay under the guise of "speedy settlement". Do not sign any undertaking or reduced option form. Any signed consent will complicate the litigation and may be argued by the AG as voluntary acceptance.
Standard writ proceedings may take time. Hence you file an urgent interim direction application for immediate payment of re-employment monthly salary, as non-payment directly affects livelihood. High Courts generally grant swift interim relief where salary is unlawfully withheld.
