(d) So fas as the seniority to the post of Secondary Grade Teacher is concerned, each panchayat union is an unit for reckoning the seniority. Accordingly, as per the seniority list which was prepared on 1.1.2011, the petitioner's place in the seniority list was assigned as per the rank assigned by the Teachers' Recruitment Board. Even for the year 1.1.2012, the seniority was prepared only based upon the rank assigned by the Teachers' Recruitment Board and not the date of joining. However, as on 1.1.2014, the seniority list was prepared for the first time based upon the date of joining. Further, in the seniority list as on 1.1.2016 prepared for promotion to the post of Elementary School Headmaster, the petitioner's juniors have been shown as senior to him. Hence, the petitioner approached the respondents to change his date of joining as on 14.12.2009 instead of 5.1.2010 since the delay in joining duty was not on account of his fault. However, the same was not considered so far. In this regard, the petitioner gave a representation dated 8.3.2016 to the respondents giving objections to the panel prepared for promotion to the post Elementary School Headmaster as on 1.1.2016 published on the notice board of the third respondent. But, the same was not considered so far. Hence, left with no other alternative, the petitioner has come up with the present writ petition for the relief set out earlier.
