One referee is on the outer goalline and watches for any goalarea violations and verifies if the ball completely crossed the goalline for a goal. The other referee is behind the attacking team, watching for any defensive or offensive fouls by the court players or any posession violations. The timekeeper looks after the time and notes the time when a player may reenter the court after a suspension or disqualification. The scorekeeper keeps the score and statistics of the match. The timekeeper and scorekeeper also assist the referees if any illegal substitutions occur.
Punishments are for progressively serious fouls.
A player is warned by the referee by displaying a yellow card that he has committed a serious foul. During that time, his team will be one player less. He may return only after serving the two minute suspension and enter through the substitution area. A team can have a maximum of 3 yellow cards. After that the remaining serious fouls are punished with 2 minute suspensions.
