Jurisdictional error
Jurisdictional error is a concept in administrative law, particularly in the UK and Australia. Jurisdiction is the "authority to decide", and a jurisdictional error occurs when the extent of that authority is misconceived. Decisions affected by jurisdictional error can be quashed by judicial review. Examples of jurisdictional errors include asking a wrong question, ignoring relevant material, relying on irrelevant material, and breaching natural justice.
