S-3.1, r. 11 - Regulation respecting combat sports

Full text
136. Where a contestant is cut as the result of an unintentional foul and the bout cannot go on by reason of the seriousness of the cut, the referee shall make a technical decision, applied to the round during which the bout is stopped, in favour of the contestant who is leading on the score cards, including the score card for the round during which the bout is stopped.
Where the bout can go on, the referee may deduct 1 or more points from the offending contestant, depending on the seriousness of the foul. The referee shall inform the judges and the chief official that the cut has been caused by an unintentional foul and that if the cut worsens as the result of a legal blow and causes the bout to be stopped, the decision must be made based on the score cards, including the score card for the round during which the bout is stopped.
If the cut worsens as the result of an illegal blow and causes the bout to be stopped, the offending contestant shall lose by disqualification.
O.C. 662-95, s. 136.
