As per case facts, petitioners, Senior Social Security Assistants (SSSAs), challenged a Tribunal order that allowed Social Security Assistants (SSAs) to be eligible for promotion to Section Supervisor. Vacancies arose ... from 2006-2017, when 1992 rules made SSAs eligible. However, 2017 regulations made only SSSAs eligible. The department notified promotions in 2018 under 2017 rules, but the Tribunal, relying on Y.V. Rangaiah, directed promotions based on 1992 rules for pre-2017 vacancies, leading to SSAs (junior and ineligible under 2017 rules) being promoted over SSSAs. The question arose whether vacancies, which arose prior to the 2017 regulations, should be filled according to the old 1992 rules or the new 2017 regulations, given that consideration started in 2018 and Y.V. Rangaiah was overruled by Raj Kumar's case. Finally, the High Court held that the Tribunal's order is perverse and set it aside. It ruled that promotions must follow rules existing on the date of consideration (2017 regulations), making only SSSAs eligible. Promotions of SSAs are to be withdrawn, and SSSAs will be considered based on merit with notional benefits.
