AI-generated headnote. Verify against the judgment before relying on it. Paragraph numbers refer to the judgment.

Summary

In a seniority dispute between Assistant Engineers recruited directly in 2000-2001 and internal candidates promoted in 2002, the Court held under the TNEB Service Regulations that training is part of duty and of appointment to the service. Seniority runs from the direct recruits' initial joining, not from the start of probation. The High Court's direction to treat all as appointed in 2002 and redraw the seniority list was set aside.

Issues

  1. Whether the seniority of directly recruited Assistant Engineers (Electrical) runs from their initial appointment, including the training period, or only from the start of probation.
  2. Whether Board Proceeding No. 9 of 23.04.2002, which reduced the direct recruits' training from two years to three months, had any bearing on inter-se seniority.
  3. Whether the proviso to Regulation 97, which fixes a cyclic order for recruits from both sources in the same calendar year, applied.

Provisions considered

Held

Result

Appeals allowed; the Division Bench judgment set aside, and the view that seniority commences from the start of probation held erroneous.
