Finance, Property, Contracts
The Union's and each State's executive power extends to carrying on trade/business, acquiring/holding/disposing of property, and making contracts for any purpose - though the Union's executive power here is subject to state legislation where the trade/purpose isn't one Parliament could itself legislate on, and vice versa for states.
This confirms that governments can act like ordinary commercial and property-holding entities - running businesses, buying and selling property, entering contracts - not just exercising regulatory/legislative power, while ensuring this commercial executive activity still respects the normal Union/State division of legislative competence in each case.
This is the constitutional basis for government-run commercial enterprises (like public sector undertakings) and for governments at both levels owning property, entering business contracts, and conducting trade as part of their executive functions.
