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.
If the offense called the infraction before the thrower began the act of throwing (3.O.3), play stops and possession reverts to the thrower.
