(2) A referee or judge shall not officiate or accept an approval to officiate when that  
assignment may impair the referee’s or judge's independence of judgment or action in the  
performance of the referee's or judge's duties. Violation of this subrule renders the  
violator subject to the penalties set forth in chapter 4 of the act, MCL 338.3640 to  
338.3649a.  
(3) A judge shall sit midway between the ring posts of a square ring, but not on the same

area.  
(5) If any individual refuses to clear the ring or ringside area when ordered to do so by  
the referee or the department representative, disputes a decision by an official, or  
encourages spectators to object to a decision either verbally or physically, then the  
individual is engaged in disruptive conduct. The referee, on his or her own initiative or at  
the request of the department representative, may stop a contest at any time until the  
disruptive conduct ceases. If the individual involved in disruptive conduct is the manager  
or second of a contestant, then the referee may order points deducted from that  
contestant's score or disqualify the contestant. If the conduct occurred after the decision  
was announced, then the department representative shall file complaints against any  
licensed individual involved in the disruptive conduct. A licensee who engages in  
disruptive conduct is subject to the penalties set forth in chapter 4 of the act, MCL  
338.3640 to 338.3649a.  
(6) The referee is the sole arbiter of a contest and is the only individual authorized to  
enter the ring at any time during competition and authorized to stop a contest. The  
referee may confer with the ringside physician in determining whether to continue or stop  
a contest.  
(7) If difficulties arise concerning language before or during a contest, the promoter

of the blow the contest cannot continue, then the injured contestant must be declared the  
loser by technical knockout.  
(2) If a contestant intentionally fouls his or her opponent and an injury or cut is  
produced, and if, due to the severity of the injury or cut, the contestant cannot continue,  
then the contestant who commits the foul must be declared the loser by disqualification.

then the referee shall penalize the contestant who commits the foul by deducting points  
based upon the severity of the offense. The referee shall notify the judges that an  
intentional unfair blow produced the injury or cut. If in the subsequent rounds the same  
injury or cut becomes so severe that the contest has to be suspended, then the judges shall  
award the decision as follows:

of the scorecards.  
(b) A technical decision to the injured contestant if the injured contestant is ahead on  
points on a majority of the scorecards.  
Page 13  
(4) If a contestant injures himself or herself trying to foul his or her opponent, then the  
referee shall not take any action in the contestant's favor, and the injury must be  
considered the result of a fair blow from the contestant's opponent.  
(5) If a contestant is accidentally headbutted in a contest and can continue, then the  
referee shall stop the action to inform the judges and acknowledge the headbutt. If in  
subsequent rounds, as a result of legal blows, the accidental headbutt injury worsens, then  
the referee shall stop the contest and declare a technical decision. The winner shall be the  
contestant who is ahead on points on a majority of the scorecards. If a contestant is  
accidentally headbutted in a contest and an injury or cut is produced and, due to the

have been completed, call the contest a technical draw.  
(b) If the contest is stopped after half of the scheduled rounds have been completed,  
declare that the winner is the contestant who has a lead in points on a majority of the  
scorecards before the round of injury.  
(6) If, in the opinion of the referee, a contestant has suffered a dangerous cut or injury,  
then the referee may stop the contest temporarily to summon the physician. If the  
physician recommends that the contestant can continue, the referee may order the contest  
to be continued. If the physician recommends that the contestant should not continue,  
then the referee shall order the contest to end.  
(7) A referee may give a contestant who receives an accidental low blow not more than  
5 minutes to recover. The referee shall direct contestants to neutral corners. The seconds  
shall not coach, administer water, or in any other way attend to their contestant. If the  
contestant cannot continue after 5 minutes, the referee shall declare that he or she is the  
loser by technical knockout.  
(8) If a contestant in a boxing contest is knocked down or given a standing mandatory 8

contest and award a technical knockout to the opponent. The physician shall immediately  
enter the ring and examine the losing contestant.

to compete, the referee shall declare the contestant as having lost by a technical knockout  
or knockout.  
(5) If an accidental foul causes an injury that is severe enough to terminate the contest  
immediately and a contest has not completed the rounds necessary to score a technical

command to box indicating the continuation of the contest.  
(7) In the final round, the timekeeper's gong terminates the fight contest.

winner's name at the designated area on the scorecard and circle the same name where  
it appears on the top of the scorecard.  
(6) If a contest is scored on individual scorecards for each round, the referee shall, at  
the end of a round, collect the scorecard for the round from each judge and shall give the  
scorecards to the department representative for computation.  
(7) Referees and judges shall be discreet at all times and shall not discuss their  
decisions with anyone during an event.  
(8) Unless the department representative determines that a computation of the  
scorecards shows a clerical or mathematical error giving the decision to the wrong  
contestant, the decision at the end of a boxing contest must not change. If such an error  
occurs, the department representative may change the decision.  
(9) The referee shall collect the scorecards from the judges and give them to the  
department representative for tabulation. After the scorecards have been tabulated, the  
referee shall collect the tabulated scorecards and give them to the announcer, who shall

R 339.230 Judging; mixed martial arts.  
Rule 230. (1) Three judges shall evaluate all mixed martial arts contests.  
(2) The 10-Point Must Scoring System must be the standard system for scoring a  
contest. Under the 10-Point Must Scoring System, 10 points must be awarded to the  
winner of the round and 9 points or fewer must be awarded to the loser, except for a rare  
even round, which is scored (10-10).  
(3) Judges shall evaluate mixed martial arts techniques, such as effective striking,  
effective grappling, effective aggressiveness, control of the cage, and defense.  
(4) Evaluation must be made in the order in which the techniques appear in subrule (2)  
of this rule. Effective striking and grappling must be the priority for round scoring.  
Effective aggressiveness must only be considered for round scoring if the judge does not  
see any advantage in effective striking and grappling. A judge may only take into  
consideration the control of the cage for round scoring when effective striking, grappling,  
and aggressiveness are even for both contestants. In the rare event that control of the cage  
is even for both contestants, a judge may take into consideration the effective defense of  
contestants.  
(5) Effective striking is judged by determining the legal blows that have an immediate  
or cumulative impact with the potential to contribute toward the end of the round. The  
immediate impact must weigh more heavily than the cumulative impact in a judge’s  
scoring of a round.  
(6) Effective grappling is judged by considering the successful execution of takedowns,  
submission attempts, reversals, and the achievement of advantageous positions that  
produce immediate or cumulative impact with the potential to contribute to the end of the  
round. The immediate impact must weigh more heavily than the cumulative impact in a  
judge’s scoring of a round. A successful takedown is not merely a changing of position,  
but the establishment of an attack from the use of the takedown. Top and bottom position  
fighters shall be assessed more on the impactful and effective result of their actions than  
their position.  
(7) Effective aggressiveness is judged by considering a contestant aggressively making  
effective attempts to finish the contest. A judge shall not consider a contestant merely  
chasing after an opponent with no effective result or impact in the scoring of a round.  
(8) The control of the cage is assessed by determining who is dictating the pace, place,  
and position of the contest.  
(9) Effective defense means avoiding being struck, taken down, or reversed while  
countering with offensive attacks.  
Page 24  
(10) The judges shall use the following objective scoring criteria when scoring a round:  
(a) A round must be scored as a 10-10 round when both contestants appear to be  
competing evenly and neither contestant shows clear dominance in a round.  
(b) A round must be scored as a 10-9 round when a contestant wins by a close margin,  
landing effective strikes or utilizing effective grappling during the competition.  
(c) A round must be scored as a 10-8 round when 1 contestant has dominated the  
action of the round, had duration of the domination, and impacted his or her opponent  
with either effective strikes or effective grappling maneuvers that diminished the abilities  
of his or her opponent.  
(d) A round must be scored as a 10-7 round when a contestant totally dominates by  
striking or grappling in a round. and stoppage is warranted.  
(11) Judges shall use a sliding scale and recognize the length of time the contestants are  
either standing or on the ground, as follows:  
(a) If the mixed martial arts contestant spent a majority of a round on the canvas, then  
both of the following apply:  
(i) Effective grappling is weighed first.  
(ii) Effective striking is weighed second.  
(b) If the mixed martial arts contestant spent a majority of a round standing, then both  
of the following apply:  
(i) Effective striking is weighed first.  
(ii) Effective grappling is weighed second.  
(c) If a round ends with a relatively even amount of standing and canvas competition,  
striking and grappling are weighed equally.  
(12) Officials who score the contest shall mark their cards in ink or in indelible pencil at  
the end of each round.  
(13) Officials who score the contest shall sign their scorecards.  
(14) Except as provided in subrule (15) of this rule, at the conclusion of each contest,  
the judges shall total the points for each contestant and indicate the winner by writing the  
winner's name at the designated area on the scorecard and circle the same name where it  
appears on the top of the scorecard.  
(15) If a contest is scored on individual scorecards for each round, the referee shall, at  
the end of a round, collect the scorecard for the round from each judge and shall give the  
scorecards to the department representative for computation.  
(16) Referees and judges shall be discreet at all times and shall not discuss their  
decisions with anyone during an event.  
(17) Unless the department representative determines that a computation of the  
scorecards shows a clerical or mathematical error giving the decision to the wrong  
contestant, the decision at the end of a mixed martial arts contest must not change. If  
such an error occurs, the department representative may change the decision.  
(18) The referee shall collect the scorecards from the judges and give them to the  
department representative for tabulation. After the cards have been tabulated, the referee

the decision to the spectators.

tabulation sheets and give them to the promoter. The promoter shall maintain the

scorecards and tabulation sheets for 1 year pursuant to section 54a of the act, MCL  
338.3654a.  
(20) If a referee becomes incapacitated and is unable to complete a mixed martial arts  
contest, then the other referee previously approved by the department for the event shall  
assume the duties of the referee.  
(21) If a judge becomes incapacitated and is unable to complete the scoring of a mixed  
martial arts contest, then the referee shall call a time-out and a licensed judge previously
