If a referee mistakenly stops the first half of a match 5 minutes short and realizes it afterward, what action should they take?

The correct action in this scenario is to report the incident to the appropriate authorities. When a referee makes a mistake regarding the timing of a match, especially one that results in an incomplete first half, it is essential to ensure that the incident is properly documented. This action helps maintain transparency in the officiating process and allows for any necessary follow-up regarding the integrity of the match.

Reporting the incident provides the governing body or league with the information needed to make a determination about how to handle the situation. This might include deciding whether the match should be restarted or replayed, or if any other disciplinary measures should be enacted.

While it may seem tempting to simply resume play or apologize, these actions do not adequately address the potential implications of cutting a half short. Ignoring the mistake would result in unresolved scoring and timing issues, which undermines the fairness of the match and can lead to disputes.
