Overview

Judicial review is the power of some courts to examine laws, administrative acts and government decisions and to declare them invalid if they conflict with a constitution or basic legal principles. It is exercised by ordinary or constitutional courts and shapes the balance among branches of government and the protection of rights. Courts that perform this role are sometimes called constitutional courts or simply courts vested with review authority.

How it works

The procedure and scope of judicial review vary by legal system. In some jurisdictions a court may strike down legislation entirely; in others it issues a declaration of incompatibility or reads statutes in a way that preserves constitutionality. Review can be concrete (triggered by an actual case) or abstract (a priori review of a statute). It typically addresses questions about statutory text, administrative decisions and the limits of executive power, including challenges to actions by the government or public agencies and claims about rights protected by the constitution.

History and development

The modern practice of judicial review in the United States is usually traced to the 1803 decision Marbury v. Madison, where the Supreme Court asserted the authority to invalidate federal statutes that conflict with the Constitution. Other countries adopted or developed forms of review at different times and often with procedural and institutional differences. The United States remains a prominent example, but many systems have parallel institutions for constitutional adjudication, including separate constitutional courts.

Examples by country

  • United States — judicial review by federal and state courts, culminating in decisions of the Supreme Court.
  • India — a vigorous system of constitutional review by the Supreme Court.
  • Ireland — judicial oversight of legislation and executive acts.
  • Malaysia — courts review executive action and statutes within constitutional limits.
  • Philippines — constitutional challenges heard by the Supreme Court.
  • England and Scotland — historically different traditions that now include forms of review and human-rights oversight.
  • Spain and Switzerland — examples of European systems with distinct approaches to review.

Significance and debate

Judicial review helps protect constitutional rights and enforce legal limits on political power, but it also raises debates about judicial activism, democratic accountability and the proper limits of courts. Supporters argue review secures fundamental rights and the rule of law; critics warn against unelected judges overturning policy choices. The balance chosen by each legal system reflects its history, constitutional text and political culture.

Different names and mechanisms (constitutional court, supreme court review, abstract review, concrete review, advisory opinions) reflect practical differences but share the basic function: resolving whether official acts conform to higher law.
