THE ORIGINAL LAWLENS SUMMARY
01

Facts

The dispute involves the inter-se seniority between Assistant Engineers (AE) recruited directly and those selected internally within the Tamil Nadu Electricity Board (TNEB).

Source reference: no citation

In December 2000 and March 2001, the Board appointed 300 AEs via direct recruitment.

Source reference: paras 3.4-3.5

Under Board Proceedings (BP) No. 35, these direct recruits were required to undergo two years of training on a consolidated pay before starting a two-year probation in a regular pay scale.

Source reference: para 3.4

Internal selection was delayed because existing employees challenged the introduction of a written examination, obtaining an interim stay in December 2000.

Source reference: paras 3.2-3.3

Eventually, the Board dispensed with the exam for internal candidates via BP No. 59 (2001) and appointed them in May 2002.

Source reference: paras 3.6-3.8

By BP No. 9 dated 23.04.2002, the Board reduced the training period for direct recruits from two years to three months, designating them as regular AEs retrospectively from the completion of said three months.

Source reference: para 3.7

The internal selectees challenged this, arguing that seniority should only count from the start of formal probation.

Source reference: no citation

The Division Bench of the High Court set aside a Single Bench order, ruling that seniority for direct recruits should only commence from April 2002, effectively treating both groups as recruited in the same calendar year.

Issues

1. Whether the period of training undergone by direct recruits is to be included in "duty" for the purpose of determining the date of appointment and subsequent seniority.

Source reference: para 20

2. Whether the seniority of direct recruits should be reckoned from their initial date of joining/training or from the date they commenced formal probation after training.

Source reference: para 7.5

3. Whether the proviso to Regulation 97, regarding the 1:1 cyclic order of seniority for candidates recruited in the "same calendar year," applies when direct recruits joined in 2000-2001 and internal candidates were appointed in 2002.

Source reference: para 7.4
03

Law Applied

The Court applied the Tamil Nadu Electricity Board (Service Regulations), 1967.

Source reference: no citation

Regulation 10(9) defines "Duty" to includes performing the duties of a post or undergoing prescribed probation or training.

Source reference: para 21

Regulation 87(1) stipulates that a person is "appointed to a class of service" the moment they first discharge duties or commence prescribed probation, instruction, or training.

Source reference: para 22

Regulation 97 states that seniority is determined by the rank in the list of approved candidates, and the date of commencement of probation is the date the individual joins duty.

Source reference: para 17, 22.1

The Court also referenced *R.S. Ajara v. State of Gujarat* and *State of H.P. v. J. L. Sharma* regarding the retroactive application of administrative decisions on seniority.

Source reference: para 7.6

Reasoning

The Court held that the Division Bench erred by ignoring the plain language of the Service Regulations.

Source reference: no citation

Under Regulations 10(9) and 87, "training" is explicitly categorized as "duty" and constitutes the commencement of "appointment to a class of service".

Source reference: paras 21-22

Therefore, the direct recruits entered the service on the date they joined for training in 2000 and 2001.

Source reference: no citation

The Court reasoned that the internal selectees' argument—that seniority only starts with formal probation—would unfairly "wash off" the service rendered during training, despite the Regulations treating training as part of duty.

Source reference: para 22.3

Furthermore, the Court found the proviso to Regulation 97 (regarding cyclic seniority) inapplicable because the two groups were not recruited in the same calendar year; the direct recruits were appointed in 2000-2001, distinct from the internal appointments in 2002.

Source reference: para 22.3

The reduction of the training period via BP No. 9 was deemed an employer’s prerogative that affected only emoluments or status, but did not alter the fundamental date of entry into service for seniority purposes.

Source reference: para 23
05

Holding

The Supreme Court allowed the appeals and set aside the Division Bench’s judgment.

It held that the seniority of direct recruits must be counted from the first date of their joining for training, as training is legally recognized as "duty" and "appointment" under Regulations 10(9) and 87.

Source reference: paras 24-25

The Court reinstated the principle that seniority is governed by the merit rank at the time of recruitment and that the training period is irrelevant to the determination of the date of entry into the cadre.

Source reference: para 22.2

All pending applications were disposed of.

Source reference: para 26
