Kangaroo Court

Kangaroo court is an informal pejorative term for a court that ignores recognized standards of law or justice, carries little or no official standing in the territory within which it resides, and is typically convened ad hoc. A kangaroo court may ignore due process and come to a predetermined conclusion. The term is also used for a court held by a legitimate judicial authority, but which intentionally or structurally disregards the court's legal or ethical obligations (compare show trial).
