The role of a referee in sports is to enforce the rules and regulations of the game, ensuring fair play and sportsmanship. Referees monitor the game and make critical decisions on fouls, penalties, and other situations that arise during play. They serve as the final authority on interpretations of the rules and intervention in disputes between players or teams. Skilled refereeing requires not only knowledge of the rules but also the ability to make quick decisions under pressure while maintaining control of the game.
