What must a referee do when a fencer commits a foul?

When a fencer commits a foul, the referee must evaluate the severity of the foul and then decide whether to issue a warning or impose a penalty. This responsibility is critical in maintaining the integrity of the sport and ensuring fair competition. It allows the referee to address inappropriate actions while considering the context and impact of the foul on the bout.

A warning may be given for minor infractions to remind the fencer of proper conduct without disrupting the flow of the competition. More serious fouls may warrant penalties, such as point deductions or disqualification, depending on the nature of the infraction. This graded approach helps to discourage foul behavior and promotes good sportsmanship and adherence to the rules.

Verbal warnings alone do not adequately address the range of fouls that can occur, and simply dismissing the foul may lead to repeated violations, undermining the discipline of the sport. Contacting a supervisor could be inappropriate during a bout, as it interrupts the match flow and can create confusion. Therefore, the referee's role is to assess the situation and take appropriate action based on their judgment and the rules of the competition.
