Authority: High Court of Judicature at Madras

Order Date: 12 June 2026

Case Overview

  • Petitioners: K. Kaliyan, M. Umapathy (W.P. No. 49914/2006) and N. Muniyandi (W.P. No. 24646/2007), former employees of Tamil Nadu Electricity Board (TNEB).
  • Respondents: 1. Tamil Nadu Electricity Board (represented by its Secretary), 2. Chief Engineer (Personnel) TNEB, 3. Superintending Engineer, Dindigul Electricity Distribution Circle, 4. Commissioner of Labour, Chennai, and a list of 37 junior employees (foremen, assistants, etc.) impleaded in their representative capacity.
  • Nature of Proceedings: Writ petitions under Article 226 of the Constitution seeking a writ of mandamus directing TNEB to promote the petitioners to Line Inspector (LI) / Commercial Inspector (CI) and subsequently to Foreman I Grade, with monetary benefits, based on seniority.
  • Key Allegations / Contentions:
  • Petitioners joined TNEB as “Helper” in 1987 (K. Kaliyan & M. Umapathy) and as “Helper” in 1974 (N. Muniyandi) and were promoted to Commercial Assistant/Wireman in the early 1990s.
  • They claim that Board Procedure No.106 dated 09‑04‑1996 re‑introduced a single‑channel promotion system, fixing inter‑seniority on the basis of seniority in the Wireman/Commercial Assistant cadre.
  • They argue that the seniority list issued in August/September 2000 (and revised in July 2006) omitted their names, placing junior respondents above them, violating B.P.No.106.
  • They rely on earlier judgments (W.A. Nos. 176 & 177/1992) upholding B.P.No.106 and contend that the double‑channel system (introduced by B.P.M.S.No.123 dated 01‑03‑1980) was not properly rescinded.
  • Respondent’s Counter‑Affidavit:
  • Asserted that the seniority list of 379 employees was published in Aug‑Sept 2000, objections were invited for two months, and none were received; therefore the list became final.
  • Explained that many junior respondents were appointed to specialized posts (Instrument Mechanic Grade I, Time Keeper, Fitter Grade I/II) which were later upgraded to LI/CI equivalents, justifying their seniority.
  • Stated that petitioners held only 5th/6th standard qualifications, insufficient for the non‑technical channel (Commercial Assistant/ACI/CI), and thus were eligible only for the technical channel.
  • Highlighted that petitioners had been promoted to Commercial Inspector in 2002/2003 and to Foreman I Grade in 2007/2008, indicating they had already benefited from the seniority list.
  • Emphasised that petitioners did not raise any objection to the seniority list when it was published, nor did they file a revision within the statutory two‑month period.
  • Court’s Reasoning:
  • The Court noted that the petitioners failed to demonstrate an enforceable legal right to the relief sought; mandamus is an extraordinary remedy requiring a clear legal right and prior demand.
  • The seniority list prepared on the basis of B.P.No.106 was lawfully published; petitioners’ silence amounted to acceptance.
  • The petitioners’ claim that they were senior to the junior respondents is untenable because the junior respondents were appointed to specialized posts that were later upgraded, placing them seniorly before the cut‑off date of 31 July 2000.
  • The Court referenced the principle that finalized seniority lists should not be disturbed as it would cause cascading disruptions (citing V. Vincent Velankanni Vs. Union of India, 2024 SCC Online 2642).
  • The Court rejected reliance on a later judgment (WP No.16603/2011) as it dealt with a seniority list dated 06‑02‑2010, which is outside the period in question.

Final Outcome

  • Both writ petitions (W.P. Nos. 49914/2006 and 24646/2007) are dismissed.
  • No costs are awarded to either side.
  • The order is pronounced on 12 June 2026.
