VAR and GLT systems may be used in accordance with the IFAB Laws of the Game for the purpose of assisting the referee.
No sources or systems other than the official VAR system may be used by the referee to review replays during the match.
The VAR system may be used in all matches of the competition. The decision as to whether the VAR system is used for all or part of a specific match is at the sole discretion of the referee, and that decision is final. The non-use of the VAR system for all or part of a match, whether due to the referee's decision or technical failure or unavailability, in no way prejudices the validity of the referee's decisions, which are final in all cases.
GLT is used in all matches of the final tournament to help the referee determine whether a goal has been scored. The referee's decision is final in all cases.
In the event of technical failure, matches may take place or continue without the use of GLT. The non-use of GLT for all or part of a match, whether due to the referee's decision or technical failure or unavailability, in no way prejudices the validity of the referee's decisions, which are final in all cases.
