Kangaroo courts are sham legal proceedings which are set-up in order to give the impression of a fair legal process. In fact, they offer no impartial justice as the verdict, invariably to the detriment of the accused, is decided in advance. Such courts are associated with groups who have found a need to dispense a rough and ready form of justice but are, temporarily at least, outside the bounds of formal judicial processes; for example, inmates in jail, soldiers at war, settlers of lands where no jurisdiction has yet been established.
A kangaroo court is often held 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.
For example, many Major League Baseball teams have a kangaroo court to punish players for errors and other mistakes on the field, as well as for being late for a game or practice, not wearing proper attire to road games, or having a messy locker in the clubhouse. Fines are allotted, and at the end of the year, the money collected is given to charity. The organization may also use the money for a team party at the end of the season.
