Judicial review in India is the power vested in the courts to examine the validity of legislative enactments and executive actions. This power allows the judiciary to strike down any law or order that is found to be inconsistent with the provisions of the Constitution, thereby upholding constitutional supremacy. It does not extend to questioning the policy or wisdom behind a law, nor does it require a pre-enactment review, nor is it primarily about reviewing its own judgments (which is covered by the doctrine of review).
