Protected service conditions do not automatically incorporate post-transfer amendments absent successor-employer adoption.

The Petitioner was appointed as a Medical Officer in DESU through UPSC in 1996 and subsequently served in DVB. Upon the statutory unbundling of DVB, her services were transferred to NDPL, later renamed TPDDL, under the Delhi Electricity Reform Act, 2000, the Delhi Electricity Reform (Transfer Scheme) Rules, 2001, and the Tripartite Agreement dated 28 October 2000.

These instruments protected the transferred employees’ existing service conditions, including those governed by the FR/SR framework and accrued service benefits.

In 2016, the Central Government and GNCTD enhanced the age of superannuation of specified categories of doctors in CHS and DHS to 65 years.

DTL, IPGCL and PPCL subsequently adopted the enhanced retirement age for their Medical Officers through decisions of their respective Boards.

The Petitioner sought similar treatment from TPDDL, relying on the protected FRSR structure, the Tripartite Agreement, and parity with employees of other DVB successor companies.

TPDDL rejected the request and treated the Petitioner as due to retire at 60 years. She was relieved on 31 May 2026.

The DVB Pension Trust initially returned her pension papers because the applicable retirement date was disputed.

The Petitioner then challenged her retirement before the High Court.

The Court applied Section 16(2) of the Delhi Electricity Reform Act, 2000, which protects transferred employees from service conditions less favourable than those applicable immediately before transfer, along with Rules 6(6) and 6(7) of the Delhi Electricity Reform (Transfer Scheme) Rules, 2001, under which employees ceased to be in DVB service but retained existing service conditions pending formulation of transferee-company regulations.

Clause 3(b) of the Tripartite Agreement protected the continuation of existing service rules, including FR/SR, while Clause 3(f) protected benefits accrued from past DVB service; these provisions did not automatically incorporate every subsequent Government amendment into the service conditions of a successor company.

Relying on Central Council for Research in Ayurvedic Sciences v. Bikartan Das, Rajeev Kumar Garg v. BSES Rajdhani Power Ltd., Mamta v. Delhi Transco Ltd., and Anju Koshal v. GNCTD, the Court held that post-unbundling Government amendments do not automatically bind a successor organisation without adoption by its competent authority.

Sushil Kumar Khanna v. BSES Yamuna Power Ltd. was distinguished because it concerned a pre-unbundling DVB benefit.

The Court also relied on Dr. R.D. Thakur v. Union of India, holding that a court cannot prescribe or enhance the age of superannuation through mandamus where no existing legal entitlement to the higher age is established.

The Court held that the statutory and contractual protections preserved the Petitioner’s existing service conditions and prevented diminution of accrued benefits, but did not create a continuing obligation to incorporate every later amendment to Government service rules automatically.

The 2016 Government orders applied expressly to specified categories of CHS and DHS doctors, and the Petitioner’s UPSC appointment in DESU did not make her a member of either service.

Further, FR 56(bb) itself contemplated specified services, functions and conditions for continuation up to 65 years; it did not confer an unconditional right on every doctor to remain in service until 65.

The adoption of the enhanced age by DTL, IPGCL and PPCL demonstrated that those entities acted through independent Board decisions; it did not establish automatic applicability to TPDDL.

Likewise, DVB Engineers Association and the APTEL decision supported parity in the specific context of wage and allowance benefits, but did not impose an indefinite obligation upon all successor companies to maintain identical service conditions, including retirement age.

TPDDL’s prior adoption of certain Government-linked benefits showed continuity of the inherited FRSR structure but not advance adoption of every future Government decision.

Since no statute, TPDDL rule, Board decision or binding settlement fixed the Petitioner’s retirement age at 65, mandamus could not be used to create that entitlement.

It held that she had no existing statutory, contractual or service-rule entitlement to continue until 65 years, and that the Court could not compel TPDDL to adopt the enhanced retirement age.

The maintainability objection concerning the writ petition against TPDDL was left open.

However, the Court directed TPDDL to identify any outstanding pension or retirement-formality documents within one week, forward the complete pension papers to the DVB Pension Trust, and release any outstanding retirement dues.

The Pension Trust was directed to process and release the Petitioner’s pension, including arrears from the date of retirement, within six weeks of receiving complete papers.

Any admitted amount unpaid beyond the stipulated period would carry simple interest at 6% per annum.
