Rules Analysis
Any time an infraction is called, the Continuation Rule applies. Continuation Rule: Play stops when the thrower in possession acknowledges that an infraction has been called.
This refers to the thrower who possesses the disc or has just released the disc at the time of the infraction/call. Who the thrower (3.O.5) is is determined at the time of the infraction/call.
An infraction affected the play if an infracted player determines that the outcome of the specific play, from the time of the infraction until play stops, may have been meaningfully different absent the infraction.
It is the infracted player's responsibility to announce if play was affected. For example, if a defender calls "pick" while trailing a receiver by 6 feet, the defender should indicate whether the pick affected the play. If the pick did not affect the play, the defender will still recover any distance lost, but the completed pass will stand. If the pick did affect the play, the disc reverts to the thrower.
For example, if a receiver is fouled and thereby prevented from getting open for a pass, the play was affected; however, if the receiver would not have received a pass even without the foul, the play was not affected.
Contact that occurs after the outcome of the play is determined cannot affect the play. For example, if a defender catches a disc before lightly bumping into the receiver, that contact did not affect the play and the turnover will stand.
