Knights accused of infractions are provided the opportunity to challenge the accusation. A Royal and/or Knightly court* (depending on the infraction) will be convened in which the accuser, the defendant, witnesses, and two observers determined by the defendant (this is up to the defendant, optional) need to be in attendance. The accused does not need to go to court if they accept the charges against them. Royalty or the Knight Regents court will deal punishment. Possible punishments are loss of rank, extra duties, removal from knighthood, etc.

Which court is at the discretion of the Queen and/or High Knight Regent and will depend on the severity of the infraction.
