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 the wrong question, ignoring relevant material, relying on irrelevant material, and breaching natural justice.
