appointed on 24.05.1984 as a Malaria Beldar on regular basis, the nomenclature of which was subsequently changed to Field Worker . The respondent-workman claimed that he was working in the Malaria Wing of the erstwhile Municipal Corporation of Delhi and that he possessed the requisite qualification for promotion to the post of Senior Field Worker. It is the case of the respondent-workman that the petitioner-management had circulated a provisional seniority list vide office order dated 21.11.2006 wherein his name appeared at Serial No.343 and his educational qualification was reflected as “9th pass”. It was further claimed that in the subsequent seniority list circulated vide office order dated 06.09.2010, his name appeared at Serial No.149. According to the respondent-workman, despite fulfilling all eligibility conditions, he was denied promotion to the post of Senior Field Worker while his juniors were granted promotion w.e.f. 24.10.2011 in the pay scale of Rs.4440-7440 with Grade Pay of Rs.1650/. The petitioner-management contested the claim before the learned Tribunal and took the stand that the respondent-workman was not eligible for promotion as he was “illiterate” and did not fulfill the eligibility criteria prescribed under the Recruitment Rules. It was contended that although the respondent-workman claimed himself to be 9th pass, he had never produced any educational certificate or marksheet in support thereof. According to the petitioner-management, upon scrutiny of the records, the respondentworkman was found ineligible for promotion by the Departmental Promotion Committee in its meeting dated 25.07.2011.
