Referee
The primary on-field official who enforces the rules, controls play, penalises fouls, awards restarts, and blows the whistle to start and stop a match.
Overview
The referee is the principal match official responsible for applying the rules, keeping order, and making binding decisions during live play. Across team invasion sports such as football, rugby, basketball, handball, water polo and ice hockey, and across combat sports such as boxing and wrestling, the referee typically carries a whistle (or gives a verbal command in the ring or on the mat) to begin, pause and restart action. Decisions are communicated through a recognized set of hand and arm signals, and the referee awards restarts such as free kicks, throw-ins, free throws or drop balls. Rulings on the facts of play are generally treated as final.
Beyond calling fouls, the referee manages player conduct: issuing warnings, cautions and dismissals (in many sports shown as yellow and red cards), penalizing misconduct, and stopping play when needed. In many sports the referee works alongside assistants — assistant referees or linesmen, a second referee, a timekeeper, or a video review official — but keeps overriding authority over decisions of fact. The exact title varies by sport: many use "referee," while others use "umpire" or "judge" for a comparable or a different role, so the referee is best understood as the central decision-maker who controls the flow and legality of a contest.
What it involves
- Whistle and signals: the referee starts, stops and restarts play with a whistle and conveys each decision through a standardized set of hand and arm signals that players and spectators can read.
- Penalising fouls and awarding restarts: when a rule is broken the referee awards the appropriate sanction and restart — a free kick, penalty, free throw, throw-in or turnover — and indicates which side benefits.
- Discipline and player management: the referee enforces conduct rules, issuing warnings, cautions and dismissals such as yellow and red cards, and can send off players for serious or repeated offenses.
- Final authority with a support crew: the referee usually leads a team of officials — assistants, a second referee, timekeepers or video review — but holds the final say on decisions of fact during play.
- Combat-sport role: in boxing and similar sports the referee controls the bout directly, separating competitors, counting knockdowns, monitoring the contest and stopping it when a competitor can no longer continue.
