Article 245

Extent of laws made by Parliament and by the Legislatures of States. (1) Subject to the provisions of this Constitution, Parliament may make laws for the whole or any part of the territory of India, and the Legislature of a State may make laws for the whole or any part of the State. (2) No law made by Parliament shall be deemed to be invalid on the ground that it would have extraterritorial operation.

In plain wordsParliament makes laws for the whole of India or any part of it, while a state legislature makes laws only for its own state. A central law cannot be struck down just because it operates beyond India's borders.
