- Factors Determining Judgement by the Panel
Given that MMA fights encompass all elements such as striking, ground techniques, etc., the judgment does not solely focus on a particular aspect of the attack but considers the overall aspects of the round. The factors influencing the judgment and their importance are as follows:
(1) Striking Attacks, Ground Strikes (Pounding)
- All threatening and damaging attacks such as punches, kicks, and pounding that do not violate the rules.
- Factors leading to effective striking (hits).
- Attacks that are deemed to have determined the outcome of the round.
- Attacks that do not inflict damage are not considered decisive factors in determining the outcome.
- While knockdowns can be signaled by the referee, whether it constitutes damage or a decisive attack determining the round's dominance is judged by the panel.
(2) Take Downs & Positional Control
- Take down involves securely grounding the opponent with throws, trips, leg hooks, tackles, etc., to gain a superior (attacker) position and must display effective (aggressive, proactive) form.
- Attempted takedowns that fail to fully ground the opponent due to continuous defensive attempts or lack of an aggressive posture are not acknowledged.
- If a takedown is executed, but the opponent's back leans against the cage and only the lower body (hips) is down, but the downed athlete does not engage in active defense but remains in that position to rest, it is considered a successful takedown.
- Positional control refers to the superior (attacker) athlete effectively pressuring the opponent in the lower (defender) position with aggressive and proactive movements.
(3) Submissions & Sweeps
- Submissions can determine round dominance based on accuracy and damage, influencing the judgment favorably.
- The declaration of a "catch" for submission attacks is made by the referee, but accuracy and damage are judged by the panel.
- A sweep in this competition refers to the lower-position athlete reversing the upper-position athlete to gain an advantageous position.
(4) Standing Timing
- If both athletes show a lack of aggressiveness or engage in meaningless attacks without inflicting damage while on the ground, the referee may stand them up to resume the match.
- Automatic Disqualification / No-Contest
(1) If a coaching staff interferes with the fight or makes direct contact with the opposing athlete or enters the cage to intervene, the respective athlete is automatically disqualified.
(2) If the referee or an authorized person representing the organization interrupts the fight due to an incident during the match, the match may be declared a no-contest.
(3) Excluding injuries from legitimate attacks, if an injury or incident occurs and it is deemed impossible to continue the match, and the situation has occurred before 2 minutes and 30 seconds of the second round, the match is considered a no-contest. If the situation occurs after 2 minutes and 30 seconds of the second round, the outcome is based on the points scored up to that point.
(4) If an athlete in the locker room refuses to follow the referee's instructions, engages in disorderly conduct, or violates the rules with abnormal behavior, making it difficult to proceed with the match, the locker room operating referee may inform the referee team and the organization to declare the match a forfeit.
