decision communicated vide said letter dated 22.06.2017. The petitioners assert that all Group 'D' posts have been re-designated as MTS and now fall in Group 'C' category and the petitioners are required to be treated as the feeder cadre for the purposes of promotion to the post of LDC. In support of such assertion, the petitioners advert to the communication dated 26.03.2013 issued by DUSIB requesting the DDOs and Assistant Director to furnish details of all Group 'D' officials, who had passed 12th grade from recognized boards and their qualifications added in their personal files/service books. According to the petitioners, it was thereafter only, the respondents issued the circular for holding departmental examination for promotion to the post of LDC. Thus, according to them, they were treated eligible and even allowed to appear for the examination scheduled for 14.06.2014, though, it came to be cancelled later. Thereafter, the petitioners made a representation on 23.02.2015 followed by a reminder dated 07.07.2015 inter alia pointing out that the petitioner No.1 - Rajesh Kumar had even served as LDC for the last two years and therefore, he should get a fair chance for promotion to the post of LDC. The petitioners allege that while their such representation remained pending consideration, vide communication dated 20.07.2016, the respondents called for the work performance reports of the similarly placed persons and in doing so, the respondents had considered all categories of posts like peon, daftari, baildar, process server but for the security guards i.e. the petitioners. Such action, according the petitioners, was discriminatory and violative of their fundamental rights of equality. They allege that there was no promotional hierarchy nor were there any notified recruitment rules for promotion for the security guards and they were stagnating on the post
