In cricket, an umpire (from the Old French nompere meaning not a peer, i.e. not a member of one of the teams, impartial) is a person who has the authority to make judgements on the cricket field, according to the laws of cricket. Besides making decisions about legality of delivery, appeals for wickets and general conduct of the game in a legal manner, the umpire also keeps a record of the deliveries and announces the completion of an over.
A cricket umpire is not to be confused with the referee who usually presides only over international matches and makes no decisions affecting the outcome of the game.
Traditionally, cricket matches have two umpires on the field, one standing at the end where the bowler delivers the ball (Bowler's end), and one directly opposite the facing batsman (usually, but not always, at square leg). However, in the modern game, there may be more than two umpires; for example Test Matches have four: two on-field umpires, a third umpire who has access to video replays, and a fourth umpire who looks after the match balls, takes out the drinks for the on-field umpires, and also arranges travel and meals for all of the umpires.
Since 2002, the ICC has two panels of umpires: namely the Elite Panel of Umpires (two of which are, in theory, appointed to each Test Match) and the larger International Panel of Umpires.
Professional matches also have a match referee, who complements the role of the umpires. The match referee makes no decisions relevant to the outcome of the game, but instead enforces the ICC Cricket Code of Conduct, ensuring the game is played in a reputable manner. The ICC appoints a match referee from its Elite Panel of Referees to adjudicate Test matches and One Day Internationals.
