Whether learning of Physics and Chemistry (at least as subsidiary subjects, if not as main subject) is mandatory for the purpose of getting appointment as HSA(Physics) in terms of the notified qualification, is the basic issue to be answered in these Original Petitions. The incidental question is whether the party respondent in OP.(KAT)No.2904 of 2013 and the petitioner in O.P.(KAT) 222 of 2015, who have studied 'Polymer Chemistry' as their main subject and have not studied Physics at any level for graduation or Post Graduation, could aspire the benefit to be included in the list, based on the orders passed by the Tribunal, the judgment passed by this Court and orders passed by the Apex Court governing the issue. Still one more issue is remaining, as to whether what shall be the benefit, if at all any to be given, by virtue of the verdict passed by the Apex Court in respect of the very same selection as HSA (a copy of which has been produced as Ext. P9 in O.P.(KAT) No.222 of 2015) and whether it could be made applicable to all similarly situated persons.
