Which concept allows the judiciary to invalidate any legislative enactment or executive order that violates the provisions or the basic structure of the Constitution?

💡 Solution & Explanation

Judicial review is the constitutional mechanism that enables courts to examine legislative acts and executive orders, declaring them null and void if they contravene the fundamental law of the land. Public interest litigation and judicial activism represent broader procedural avenues rather than the power to invalidate laws. Constitutional principles are central to civil services exams.
