The International Football Association Board Laws of the Game

Extract from  IFAB Laws No 5 Referees – 27th May 2016

1. The authority of the referee

Each match is controlled by a referee who has full authority to enforce the Laws of the Game in connection with the match.

2. Decisions of the referee

Decisions will be made to the best of the referee`s ability according to the Laws of the Game and the ‘spirit of the game’ and will be based on the opinion of the referee who has the discretion to take appropriate action within the framework of the Laws of the Game.

The decisions of the referee regarding facts connected with play, including whether or not a goal is scored and the result of the match, are final.

The referee may not change a decision on realising that it is incorrect or on the advice of another match official if play has restarted or the referee has signalled the end of the first or second half (including extra time) and left the field of play or terminated the match. If a referee is incapacitated, play may continue under the supervision of the other match officials until the ball is next out of play.

• enforces the Laws of the Game
