Union Territories & Panchayats
(1) Parliament may by law constitute a High Court for a Union Territory, or declare an existing court to be a High Court for constitutional purposes. (2) Chapter V of Part VI (the High Courts chapter) applies to such a High Court as it applies to a State's High Court, subject to modifications Parliament may specify. (3)-(4) Pre-1956 jurisdictional arrangements continue, and this doesn't limit Parliament's power to extend/exclude a State High Court's jurisdiction over a Union Territory.
Parliament has flexibility in how it provides judicial infrastructure for Union Territories - it can create a dedicated High Court just for a UT, or (more commonly, as seen in Article 230) simply extend a neighbouring State's existing High Court to cover that territory instead.
Delhi is a notable exception among Union Territories in having its own full dedicated High Court (the Delhi High Court), constituted under this article, rather than sharing a High Court with a neighbouring state.
