Judicial review is a type of court proceeding in which a judge reviews the lawfulness of a decision or action made by a public body.

Judicial Review is a process by which individuals can challenge the lawfulness of decisions or actions of the executive, including those of Ministers, Local authorities, other public bodies and those exercising public functions. It is largely judge-developed procedure and can be characterised as the rule of law in action. It is, however, intended to function quickly and proportionately. Certain protections are in principle provided against spurious claims, and they usually work in practise, Judicial Review is not available if there is an alternative remedy (such as statutory right of appeal); only those with sufficient interest in the outcome are able to bring case and they must first obtain permission for their case to be heard.
