Delhi High Court (Sanjeev Narula, J., oral, 25.02.2026), composite adjudication of five writ petitions by retired FCI executives over the shift from the CDA to the IDA pay pattern. Background: Supreme Court common judgment dated 03.05.1990 (following HPPC report) drew a 01.01.1989 cut-off and preserved a voluntary option for pre-cut-off CDA employees; contempt directions of 25.01.1993 opened the option window for FCI; yet pre-1989 entrants continued on CDA through promotions. DPE O.M. dated 10.08.2009 read 'promotion' into 'appointment'; DPE O.M. dated 12.07.2010 made it retrospective; FCI circular dated 30.09.2011 effected retrospective CDA-to-IDA conversion from first promotion on/after 01.01.1989 with recovery of 'excess'; after the interim order of 22.02.2013, FCI circular dated 24.05.2013 (reiterated 05.01.2015) permitted recoveries while keeping payment cases pending. HELD: (i) recovery from retired employees and withholding of gratuity, leave encashment or other retiral dues founded on such belated refixation are impermissible absent fraud or misrepresentation — the retirees fall squarely within the protected zone of State of Punjab v. Rafiq Masih (2015) 4 SCC 334; the 1990 Supreme Court judgment binds under Article 141 and a forced adverse retrospective conversion would be arbitrary; relief framed narrowly, without ruling on 'promotion = appointment' generally, and without barring voluntary election of IDA where favourable; (ii) the recoveries-proceed/payments-pending posture is an administrative asymmetry unsustainable in public law — the 22.02.2013 order never authorised it, and a State instrumentality bound by Article 14 must apply a scheme it elects to operationalise even-handedly; restitution concerns are met by refund undertakings, not denial; the 24.05.2013 and 05.01.2015 circulars were set aside to the limited extent they mandate that regime. Directions: no recovery/refund within eight weeks with 6% p.a. interest; release of withheld dues within eight weeks with 6% p.a.; payment-side petitions allowed — computation and release within ten weeks of arrears and consequential dues including differential gratuity on IDA refixation from first promotion (26.12.2008 for W.P.(C) 9195/2015), extended to 'left-out beneficiaries' in W.P.(C) 12187/2019, with 6% p.a. interest from 01.03.2013 till payment.
