Trial by Combat
Before the Humans gained dominance of the Noble Court, and instated the Whisper Vote as the main method of trial and judgement, the court often used Trial by Combat to settle differences and disagreements.
History
The last trial by combat was between Vizier Jafar Darktusk and then-Vizier Saladin Greenskin, the Second. Saladin was victorious when Jafar conceded and withdrew his accusations; it is possible the combat is how Jafar ended up in a wheelchair.
