Laws of the Game 2006
THE FOURTH OFFICIAL
 
  • He must indicate to the referee when the wrong player is cautioned because of mistaken identity or when a player is not sent off having been seen to be given a second caution or when violent conduct occurs out of the view of the referee and assistant referees. The referee, however, retains the authority to decide on all points connected with play.

  • After the match, the fourth official must submit a report to the appropriate authorities on any misconduct or other incident that has occurred out of the view of the referee and the assistant referees. The fourth official must advise the referee and his assistants of any report being made.

  • He has the authority to inform the referee of irresponsible behaviour by any occupant of the technical area.
