Case Note & Summary
The dispute arose regarding the effective date of merger between the Exploration Wing of the Indian Bureau of Mines (IBM) and the Geological Survey of India (GSI). The appellants, representing GSI, argued that the merger occurred on 4 February 1969, while the respondents, originally from IBM, contended it was effective from 1 January 1966. The Bombay High Court ruled in favor of the respondents, leading to appeals by the GSI. The Supreme Court examined various letters from the Government of India, concluding that the transfer of administrative control occurred on 1 January 1966, but the actual merger of posts was sanctioned later, on 4 February 1969. The court emphasized that the provisional seniority list and related documents did not serve as evidence for the merger date. Ultimately, the Supreme Court allowed the appeals, affirming the later merger date and clarifying the implications for seniority and promotions within the merged departments.
