Ouster clause
An ouster clause or privative clause is, in countries with common law legal systems, a clause or provision included in a piece of legislation by a legislative body to exclude judicial review of acts and decisions of the executive by stripping the courts of their supervisory judicial function. According to the doctrine of the separation of powers, one of the important functions of the judiciary is to keep the executive in check by ensuring that its acts comply with the law, including, where applicable, the constitution.
