The High Court is the appropriate venue for applications for judicial review in the UK. A person who believes that an exercise of public power, such as a parole board's decision, is unlawful can apply to the Administrative Court, a division of the High Court, for judicial review. If successful, the court may quash the unlawful act. Under the Human Rights Act 1998, public bodies must act compatibly with Convention rights. While the High Court cannot strike down primary legislation (to maintain the sovereignty of Parliament), it can issue a declaration of incompatibility if it finds the legislation contravenes the HRA. 

Key Point: The High Court is responsible for hearing applications for judicial review, providing a mechanism for individuals to challenge the legality of decisions made by public bodies, particularly in cases involving potential human rights violations.
