VAR (Video Assistant Referee) refers to a team of match officials who have access to live video footage of the game from multiple camera angles. They are stationed in a separate video operation room (VOR) and can review incidents that the on-field referee might have missed or made a mistake on.
According tot the Laws of the Game, the use of video assistant referees (VARs) is only permitted where the match/competition organiser has met all the Implementation Assistance and Approval Programme (IAAP) requirements as laid out in FIFA's IAAP documents, and has received written permission from FIFA.
VAR can only intervene in four specific situations where a "clear and obvious error" or "serious missed incident" has occurred:
In addition to the principles in relation to goal/no goal, penalty/no penalty, direct red card, and mistaken identity incidents, there are more VAR principles as follows:

The concept of VAR arose from a growing need to address critical officiating errors. The traditional referee system, although central to football's integrity, often fell short in the face of the game's rapid pace and complexity. To combat these challenges, the International Football Association Board (IFAB) and FIFA worked on a series of trials and tests, eventually leading to VAR's formal implementation. Its successful debut in the 2018 FIFA World Cup set the stage for widespread adoption across major leagues such as the Premier League, La Liga, Serie A, and the Bundesliga.
