Greetings and welcome to another episode of our Crunching Concepts series. Our discussion today revolves around 'ultra vires', an instrumental concept in UK constitutional law. Although it may sound labyrinthine, ultra vires is a cornerstone of public law, deeply ingrained in the functioning of public authorities. Strap in as we unpack this concept and investigate its use in practice.
Ultra vires is a Latin phrase meaning 'beyond the powers'. In the frame of UK constitutional law, it refers to situations when public authorities exceed their lawful powers by acting beyond the scope of authority vested to them. If an authority acts ultra vires, its actions could be labelled void and potentially annulled by a court of law.
The notion of ultra vires plays an indispensable role in holding public authorities responsible and ensuring they function within legal boundaries for these reasons:
1. Upholding Rule of Law: Ultra vires constrains authorities from overstepping their powers, thereby preserving the rule of law and upholding the principle of legality.
2. Ensuring Accountability: The notion is a vital instrument for holding public authorities accountable for their actions.
3. Judicial Review: This essential mechanism for reining in public authorities often involves assessing whether an authority has acted ultra vires.
To elucidate the concept further, let's look at some landmark cases that underscore the doctrine of ultra vires:
• Anisminic Ltd v. Foreign Compensation Commission [1969] 2 AC 147: This milestone case established that even decisions by expert tribunals could be open to judicial review for ultra vires.
• Council of Civil Service Unions v Minister for the Civil Service (GCHQ) [1984] UKHL 9, [1985] AC 374: This case ruled that decisions made under royal prerogative, too, could be open to judicial review for ultra vires.
• R (on the application of Miller and another) (Respondents) v Secretary of State for Exiting the European Union (Appellant) [2017] UKSC 5: In this case, the UK Supreme Court decided that the Government acting to trigger Article 50 without an Act of Parliament was ultra vires.
