230. (l) His Majesty in Council may, if satisfied that an agreement in that behalf has been made between the Governments concerned, extend the jurisdiction of a High Court, in any Province to any area in British India not forming part of that Province, and the High Court shall thereupon have the same jurisdiction in relation to that area as it has in relation to any other area in relation to which it exercises jurisdiction.
(2) Nothing in this section affects the provisions of any law or letters patent in force immediately before the commencement of Part III of this Act empowering any High Court to exercise jurisdiction in relation to more than one Province or in relation to a Province and an area not forming part of any Province.
(3) Where a High Court exercises jurisdiction in relation to any area or areas outside the Province in which it has its principal seat, nothing in this Act shall be construed-
(a) as empowering the Legislature of the Province in which the Court has its principal seat to increase, restrict or abolish that jurisdiction; or
(b) as preventing the Legislature having power to make laws in that behalf for any such area from passing such laws with respect to the jurisdiction of the court in relation to that area as it would be competent to pass if the principal seat of the court were in that area.
