Can the states entrust functions to the Union, and under what conditions?
Yes, the states can entrust functions to the Union under certain conditions. These conditions are laid out in Article 258 of the Indian Constitution which states that "Parliament has power to make laws for the whole or any part of the territory of India and such power may extend to making laws with respect to any matter for which provision is made by this Constitution for the exercise of legislative powers by the Legislature of a State as well as to making laws for implementing any treaty, agreement or convention with any other country or countries or any decision made at any international conference, association or body." This power can be exercised only with the consent and adoption of such legislation by any other state.
