Is it considered Fraud if a player (or teammate) notices an offense during their match and does not call attention to it?

The concept of Fraud in Magic: The Gathering tournament play involves intentionally misleading or deceiving other players or tournament officials for personal gain. In this context, if a player or their teammate notices an offense during the match and chooses not to call attention to it, it is considered a failure to act on an observed rule violation.

The expectation in tournament play is that players have a responsibility to uphold the integrity of the game. Relaying observed infractions is crucial to ensuring that all players are competing under the same rules and conditions. When a player witnesses a violation and remains silent, it can be interpreted as an attempt to allow that infraction to go uncorrected, which could unfairly benefit that player or their team.

Thus, the answer indicates that not reporting a recognized infraction certainly aligns with the conduct that constitutes Fraud. It reflects a willful decision to remain complicit in an unfair advantage rather than fostering a fair competitive environment. This adherence to fair play is fundamental to maintaining trust and integrity in the game.
