Ultra Vires - Administrative Law

Administrative Law

In administrative law, an act may be judicially reviewable for ultra vires in a narrow or broad sense. Narrow ultra vires applies if an administrator did not have the substantive power to make a decision or it was wrought with procedural defects. Broad ultra vires applies if there is an abuse of power (e.g., Wednesbury unreasonableness or bad faith) or a failure to exercise an administrative discretion (e.g., acting at the behest of another or unlawfully applying a government policy) or application of discretionary powers in irrational and wrong way. Either doctrine may entitle a claimant to various prerogative writs, equitable remedies or statutory orders if they are satisfied.
