Checks on abuse of discretion
⚖️ Checks on Abuse of Discretion in Administrative Law
Discretion in administrative law refers to the power granted to decision-makers to choose between different options or courses of action within legal boundaries. However, this discretion is not absolute. It must be exercised lawfully, reasonably, and for the proper purpose. Courts intervene where discretion is abused—meaning exercised in a way that is unlawful, irrational, or unjust.
What Constitutes Abuse of Discretion?
An abuse of discretion occurs when a decision-maker:
Acts beyond or outside the scope of their legal power (ultra vires).
Acts for an improper purpose.
Acts irrationally or unreasonably.
Fails to consider relevant factors or considers irrelevant factors.
Acts capriciously or arbitrarily.
Fails to follow procedural fairness.
Acts in bad faith or with bias.
