Remedies in Singapore administrative law
The remedies available in Singapore administrative law are the prerogative orders – the mandatory order (formerly known as mandamus), prohibiting order (prohibition), quashing order (certiorari), and order for review of detention (habeas corpus) – and the declaration, a form of equitable remedy. In Singapore, administrative law is the branch of law that enables a person to challenge an exercise of power by the executive branch of the Government. The challenge is carried out by applying to the High Court for judicial review. The Court's power to review a law or an official act of a government official is part of its supervisory jurisdiction, and at its fullest may involve quashing an action or decision and ordering that it be redone or remade. A mandatory order is an order of the High Court commanding a public authority to perform a public duty, while a prohibiting order operates to prevent illegal action by an authority from occurring in the first place.
