Can a referee change a decision once it has been made?

A referee can indeed change a decision if new information reveals an error. In the spirit of ensuring fair play, the Laws of the Game allow referees to reconsider their decisions upon gaining additional insights or clarity regarding a situation. This means that if, for example, the referee receives information from other match officials or has a clear view of an incident that contradicts the original decision, they have the authority to amend their ruling to accurately reflect what occurred.

The emphasis on correcting mistakes highlights the dynamic nature of officiating soccer, as it prioritizes fairness and accuracy. Thus, this understanding aligns with the officiating philosophy that accepts human error and the need for rectification when necessary.
