Under what condition can referee decisions be reviewed?

The correct answer emphasizes that referee decisions can be reviewed specifically in cases of obvious error. This principle is rooted in the need for fair play and integrity within the game. The purpose of allowing for reviews is to ensure that critical decisions impacting the outcome of the match are accurate and justified. An obvious error refers to a significant mistake that is clear upon review, such as missing a clear foul, a goal that should not have counted, or a card that was unjustly issued.

The context around this process is vital, as it highlights the situational appropriateness of when a review can take place, restricting it to credible claims where the integrity of the match is at stake. Referees maintain the authority to make decisions on the spot, but the review mechanism acts as a safeguard against clear injustices.

The other conditions presented do not meet the criteria for when a referee's decision may be reviewed. Player appeals can occur for various reasons, but that does not automatically lead to a review process. Scoring more than three goals or ties at the end of a match do not relate to the review of referee decisions in the context of errors. These factors are strategic outcomes and do not influence the review process tied to the integrity of decision-making during the game.
