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.
Where the thrower calls an infraction which occurred before the thrower began the act of throwing, play continues unhalted and the result of the play stands.
