This document contains a judgment from the Jharkhand High Court concerning the retrospective application of the 10% Economically Weaker Section (EWS) quota. The court ruled that applying this quota retrospectively to vacancies from 2013 and 2015 is unconstitutional, violating Articles 14 and 16 of the Indian Constitution. The judgment directs the modification of Advertisement No. 05 of 2019 to remove the retrospective EWS quota and advises filling the vacancies from 2013 and 2015 according to the rules applicable at that time.
