Kangaroo court

A judicial tribunal or assembly that blatantly disregards recognised standards of law and justice, and often carries little or no official standing in the territory within which it resides. The term may also apply to a court held by a legitimate judicial authority which intentionally disregards the court’s legal or ethical obligations. It usually occurs in circumstances where the intention is to give the appearance of a fair and just trial, even though the verdict has in reality already been decided before the trial has begun.
