The use of foul language, cursing, or other immoral acts of disrespect towards the referee or any of the assisting public.
Biting, hair pulling, putting fingers into the eyes or nose of one’s opponent is illegal. Intentionally seeking to injure genitalia or use fists, feet, knees, elbows, or head with the intention to hurt or gain unfair advantage is illegal. Slamming your opponent from the guard is illegal.
When the fighter has his gi ripped during the fight, the referee will give him a set time to change it. If the fighter does not change it in time he will be disqualified.
Competitors must wear underwear under their gi pants and nogi grappling shorts. This keeps in mind the risk that the gi or grappling shorts might get torn open. If this occurs, the athlete will be given a set time determined by the referee to find another pair of gi pants or shorts to wear. If the athlete cannot change within the set time, he will be immediately disqualified.
The decisions of the referees and Tournament Officials are 100% FINAL.
