Lord Scarman

I believe that the law relating to judicial review has now reached the stage where it can be said with confidence that, if the subject matter in respect of which prerogative power is exercised is justiciable, that is to say if it is a matter upon which the court can adjudicate, the exercise of the power is subject to review in accordance with the principles developed in respect of the review of the exercise of statutory power... Today, therefore, the controlling factor in determining whether the exercise of prerogative power is subject to judicial review is not its source but its subject matter.
