Who has the authority to extend or exclude the jurisdiction of a High Court over a Union Territory?

According to Article 241 of the Indian Constitution, only Parliament has the authority, through legislation, to extend or exclude the jurisdiction of a High Court over a Union Territory. This is evident in how the Delhi High Court has jurisdiction over Delhi, the Madras High Court over Puducherry, and the Kerala High Court over Lakshadweep. The Chief Justice of India can only recommend such changes, while the President acts on the advice of the Council of Ministers. State legislatures have no role in determining High Court jurisdiction over Union Territories.
