It is submitted that respondent-Haryana Public Service Commission caused an advertisement No.3/2018-19 dated 02.08.2018, inviting the applications for filling up Group A & B posts i.e. HCS (Ex. Branch) and other allied services, wherein 2 (two) posts of HCS (Ex. Branch) and 3 (three) posts of other allied services were reserved for ESP Category. Petitioners, having Grade 'A' Certificate and requisite qualification, applied for the said posts and participated in Preliminary Exam, held on 31.03.2019. They further submitted that as per result dated 21.05.2019 (Annexure P-5), many candidates, who sat in preliminary examination and having Grade 'B' and 'C' Certificates, have also been considered eligible. Information received under Right to Information Act, 2005 (Annexure P-6, Colly), reveals that candidates, who had been issued Grade 'A' Certificate, as per new policy dated 25.05.2018, are only 13 (thirteen) in number, whereas result reveals more than that and therefore, action of the respondent-HPSC in preparation of the result, is wholly illegal and fallacious.
