Judicial review proceedings may brought against any person or entity (usually a government or quasi-government body) that has exercised a statutory power. The typical case involves a plaintiff who has been affected by a government decision and wishes to challenge the way in which the decision was made. Arguments available include that the decision maker breached principles of natural justice, made an error of law, made a mistake of fact, failed to take into account relevant considerations or took into account irrelevant considerations, or was unreasonable. All judicial reviews are heard in the High Court and appeals may be made to the Court of Appeal. The Court will scrutinise the decision-making process and, if it finds errors, usually send the decision back to the decision-maker for correction.
