kangaroo court

"Kangaroo court" is a term used to describe a judicial or quasi-judicial proceeding that lacks fairness, impartiality, or is characterized by a mockery of justice. This phrase is typically used to criticize a legal process or trial that is perceived as being biased, predetermined, or where the outcome is predetermined and unfair. The term "kangaroo" is used metaphorically to imply that the court is jumping to conclusions or acting in a manner that appears ridiculous and whimsical, similar to the hopping of a kangaroo.
