A foul occurs when contact is made. When a player initiates contact on another player a foul occurs. When a foul disrupts possession, the play resumes as if the possession was retained. If the player committing the foul disagrees with the foul call, the play is redone. Self-Refereeing Players are responsible for their own foul and line calls.
Players resolve their own disputes.
