If an umpire erroneously calls "fault" and immediately corrects himself and calls "play" but the striker fails to return the ball, a "let" is allowed. Umpires serve for an entire match, unless a change is authorized by the tournament committee. Each of the two (or more) line referees is responsible for one boundary line and one half of the side line opposite the umpire, in addition to any other duties assigned by the umpire. Referees signal the umpire in a code prescribed by the BBF. The scorer records the points scored and the number of hands on the score sheet. A ball may be replaced by an umpire if it is lost or damaged. The umpire can overrule a line referee's decision, if he feels that an error has been committed. The umpire is also responsible for the net. He announces the score (for the benefit of the scorer) when a point is scored or a server is out. In announcing the score he calls the number of the serving hand, followed by the score of the serving team and the score of the other team. If a match is suspended by the umpire for any reason (e.g. weather and light), it is resumed from the point at which it was stopped. In case of a tie between two or more teams in any tournament, a match is not replayed. If the tie is unbroken, teams are ranked based on game and point scores. In a league tournament, if two (or more) teams have identical won/lost records their game scores are used to break the tie. Game Scoring The number of games won and lost by each team in each league match is recorded. Keeping in mind that each match is played as a best of three games, a team winning a match after three games has won two games and lost one. If a team wins a match in two straight games, its official won/lost record is 3–0. The losing team in each case has a record of 1–2 and 0–3, respectively. The difference between the number of games won and lost is a team's game score. The team with the highest game score is the winner in the event of a tie; if two or more teams have the same game score, their point scores will also break the tie.
