Seniority in a promotional cadre is fixed at appointment; later qualification does not restore prior seniority.

The petitioner participated in the 2010 recruitment process for Assistant Engineer and was appointed on 20 February 2012 after litigation delayed the appointment. Although the Service Rules were amended with effect from 3 November 2010 to require a Master’s Degree in Environmental or Chemical Engineering, he was appointed without the postgraduate qualification because his recruitment process had commenced earlier. His appointment was regularised on 15 February 2014, with his seniority shown below S. Ravichandran and above the second respondent, C. Vanaja.

For promotion to Assistant Environmental Engineer, the petitioner lacked the prescribed postgraduate qualification and was therefore not included in the promotion panels for 2017–18, 2018–19 and 2019–20. The private respondents, who possessed the qualification, were promoted during the 2017–18 panel. After acquiring the postgraduate degree on 3 March 2020, the petitioner was promoted as Assistant Environmental Engineer in the 2020–21 panel.

The petitioner claimed that, upon acquiring the qualification, his original seniority in the Assistant Engineer cadre should be restored and that he should be placed above the private respondents for promotion as Environmental Engineer. The Tamil Nadu Pollution Control Board rejected that claim, leading to the writ petition challenging the panel/order and the consequential memorandum.

Whether the petitioner’s original seniority in the Assistant Engineer cadre was required to be restored upon his subsequently acquiring the qualification for promotion as Assistant Environmental Engineer?

Whether the petitioner was entitled to be placed above the private respondents in the seniority list for the promotional post of Assistant Environmental Engineer and consequently be considered for promotion as Environmental Engineer for 2022–23?

The Court applied Regulation 20 of the Tamil Nadu Pollution Control Board Revised Service Regulations, 2010, under which seniority in a service category is determined by the rank obtained in the approved list of candidates for appointment to that category.

Regulation 10(3) requires appointments to be made from the approved list in the order of merit and seniority.

Regulation 26(2) provides that no appointment or promotion should ordinarily be made unless the person possesses the qualifications prescribed for the post.

Rule 3 of the Tamil Nadu Pollution Control Board General Service Part II Rules prescribes the method of appointment and qualifications for Environmental Engineer, Assistant Environmental Engineer and Assistant Engineer; promotion to Assistant Environmental Engineer requires the prescribed postgraduate qualification or the requisite experience, while promotion to Environmental Engineer requires five years’ experience as Assistant Environmental Engineer or ten years’ combined experience in the two posts.

The Court construed “promotion” under Rule 3 as an appointment to the promotional post, making seniority dependent on the approved list prepared for that post.

The Court rejected the petitioner’s contention that delayed acquisition of the postgraduate qualification merely postponed his promotion while preserving his original seniority. Although his seniority in the Assistant Engineer cadre was initially above the private respondents, he could not be appointed or promoted as Assistant Environmental Engineer until he satisfied the qualification requirement under Regulation 26(2) and Rule 3.

The private respondents were validly appointed to the promotional post during the 2017–18 panel, whereas the petitioner became qualified and was appointed only in the 2020–21 panel.

Since Regulation 20 determines seniority by the rank in the approved list for the relevant category, the petitioner’s seniority in the promotional cadre had to be determined with reference to the list prepared when he was appointed to that cadre.

In that list, the private respondents ranked above him; therefore, his earlier seniority as Assistant Engineer did not entitle him to retrospective restoration or precedence in the promotional cadre.

The private respondents, having been appointed to the promotional post earlier, were senior to him under Regulation 20.

The writ petition challenging the impugned proceedings and seeking placement above the second respondent and promotion as Environmental Engineer was dismissed; the connected miscellaneous petitions were closed, with no order as to costs.
