Article 253 of the Constitution empowers Parliament to make laws for the whole or any part of India for implementing any Treaty, Agreement or Convention with another country or countries, or any decision taken at an International Conference, Association or other Body.

A significant feature of this Article is that, for implementing an international obligation, Parliament can legislate even on a subject that would ordinarily fall within the State List. Therefore, the power mentioned in the question to legislate on a State List subject for giving effect to an international agreement is associated with Article 253.

The distinction among the other options is also important—under Article 249, Parliament may legislate on a State List subject when the Rajya Sabha passes a resolution in the national interest; Article 250 permits it during a National Emergency; while Article 252 permits Parliament to legislate for two or more States when those States consent to such legislation.
