Case Note & Summary
The dispute arose between the Delhi Water Supply and Sewage Disposal Undertaking and certain Executive Engineers regarding the determination of their seniority following their regularisation. The appellants contended that their seniority should reflect their rankings in the cadre of Assistant Engineers, while the respondents argued that continuous officiation in the post should govern seniority. The Delhi Municipal Corporation Act, 1957, provided the framework for appointments and seniority, but the applicability of the Delhi Municipal Corporation Service Regulation, 1959, was contested. The Supreme Court examined the principles of service jurisprudence, particularly the relevance of continuous officiation and ad hoc service in determining seniority. The court emphasized that ad hoc service should only be counted if it was made after considering the claims of seniors in the cadre. The court ultimately upheld the view of the Delhi High Court that continuous officiation should be the basis for seniority, dismissing the appeals and affirming the principle of equality of opportunity in public service. The court found no merit in the appellants' arguments regarding the applicability of the service regulations and the method of ad hoc appointments, concluding that the decisions made by the High Court were correct and did not warrant interference.
