What does 'kangaroo court' mean?

Answer:
A "kangaroo court" refers to sham legal proceedings where the outcome is decided more or less in advance, regardless of witnesses and the appearance of genuine proceedings. Such a court is usually unauthorised and does not observe the usual protocol of a court of law.
