Once India signs an international treaty, it automatically becomes enforceable law inside the country.

Courts have held that treaties are not self-executing in India; Parliament must pass a specific law under Article 253 to make the treaty's terms enforceable domestically.

Article 253 lets the executive override state laws directly without Parliament's involvement.

The power under Article 253 belongs to Parliament (the legislature), not the executive; a formal law must be passed, not just an executive order or treaty signing.

The Constitution of India

Article 253

Legislation for giving effect to international agreements

Notwithstanding anything in the foregoing provisions of this Chapter, Parliament has power to make any law for the whole or any part of the territory of India for implementing any treaty, agreement or convention with any other country or countries or any decision made at any international conference, association or other body§

Why this exists

India's Constitution divides law-making subjects between the Union and the States. But international commitments—like environmental treaties, trade agreements, or human rights conventions—often touch on subjects (health, agriculture, local resources) that fall under the State List. The framers, aware that India needed to reliably honor its international obligations without being blocked by federal divisions, gave Parliament an overriding power to legislate nationally whenever implementation of a treaty or international decision required it. This ensures India speaks and acts as one nation on the world stage.

How courts read it

In Maganbhai Ishwarbhai Patel v. Union of India (1969), the Supreme Court clarified that while the executive can enter into treaties under Article 73, actually changing citizens' rights or state laws to implement a treaty requires separate legislation—often under Article 253. Later, in Gramophone Company of India Ltd. v. Birendra Bahadur Pandey (1984), the Court held that international treaties do not automatically become enforceable domestic law in India; Parliament must transform them through legislation, confirming India's 'dualist' approach to international law. Courts have also referenced Article 253 (alongside Article 51(c)) when drawing on international conventions like CEDAW to fill gaps in domestic law, as in Vishaka v. State of Rajasthan (1997), though that case rested more directly on constitutional interpretation than a fresh Article 253 law.
