Background
Background
The Supreme Court of Pakistan held that WAPDA's 2018 service rules could operate prospectively but could not unsettle seniority and promotion rights already accrued under the previous regime.
WAPDA's 2018 service rules separated the seniority streams of Assistant Station Attendants in Operations and Maintenance. Employees appointed under the earlier combined regime challenged the resulting loss of ranking and promotion prospects.
Can new service rules retrospectively disturb settled seniority?
Can new service rules retrospectively disturb settled seniority?
Whether WAPDA's 2018 service rules could be applied retrospectively to disturb the settled seniority and promotion eligibility of employees already serving under the previous rules.
Court holding
What the Court decided
No. Seniority and promotion eligibility are substantive service rights. In the absence of clear and legally effective retrospective operation, the 2018 Rules applied prospectively and could not unsettle seniority acquired under the former regime.
Final outcome
Final outcome
All twenty-five petitions were dismissed and leave was refused. The Federal Service Tribunal's directions restoring the earlier combined seniority for existing employees, protecting completed promotions and granting consideration from the dates juniors were promoted remained intact.
Practical effect
What the decision means in practice
Departments revising cadres or promotion streams should preserve and expressly address the seniority of existing employees. Affected employees should document the governing rules, seniority lists, promotion dates and comparative position of juniors.
This summary states the immediate effect recorded in the decision. The original judgment and the facts of the particular case remain controlling.
Key legal principles
Key legal principles
- New laws and rules are presumed to operate prospectively unless retrospective effect is stated with unmistakable clarity.
- Seniority and eligibility for promotion are substantive service rights, not merely procedural arrangements.
- A later rule cannot ordinarily destroy seniority lawfully acquired under the rules in force at the relevant time.
- Retrospective disruption of settled ranking may violate legitimate expectation and become arbitrary, discriminatory and prejudicial.
- A valid new cadre or progression structure may govern future entrants while accrued rights of existing employees remain protected.
