0 (in the UK) the process in which a decision made by a government department or other public organization is examined by a court of law to decide whether it was right or not:
1 (in the US) the process by which the Supreme Court decides whether something can be allowed according to the Constitution (= the set of political principles by which the United States is governed):
One of the Court's most fundamental powers is judicial review – the power to judge the constitutionality of any act or law of the executive or legislative branch.
But judicial review need not, and should not, occur to the exclusion of legislative rights review.
This would mean that more legislation is completely undone by judicial review.
My second example concerns the common practice of coupling such constitutional provisions with judicial review.
Students of judicial history must remember that judicial review had to be established both legally and politically.
However, judicial review is likely to possess less legitimacy than a political process.
Executive regulations, as well as laws, are subject to judicial review.
Parliament is, in their view, the supreme lawmaking body and therefore its internal rules are not subject to judicial review.
Despite the general recognition that some form of judicial review is desirable, if not necessary, for the functioning of democratic regimes, the practice remains controversial.
