Extension of High Court jurisdiction permits Parliament to extend or exclude jurisdiction over Union Territories and establish common High Courts.

Parliament may by law extend or exclude a High Court's jurisdiction over any Union Territory, with State legislatures barred from altering such jurisdiction; references to the Governor for subordinate court rules in that territory are to be read as references to the President. Parliament may also establish a common High Court for multiple States or States and a Union Territory, and constitutional references (to Governors, subordinate court governance, and to State institutions for the principal seat) are to be construed with respect to the States served or, where the principal seat lies in a Union Territory, as references to Union authorities.
