A merged union territory, the High Court that covers it, and the districts it joined
Background
A union territory does not get a High Court of its own merely because it is created by a merger. When the two union territories were joined, the law kept the existing court arrangement in place. The jurisdiction of the High Court of Bombay continues to extend to the merged union territory. Dadra and Nagar Haveli had a single district before the merger, while Daman and Diu already had two districts. Those districts were carried into the one merged union territory. A stated reason for the merger was the policy of Minimum Government, Maximum Governance, under which two separate secretariats were treated as wasteful. The number of union territories in the country was to come down to eight. A court's jurisdiction is a standing fact about a territory, and a merger does not reset it.
In plain words
