If the thrower calls a foul before they are in the act of throwing, play must stop. If the thrower does incorrectly continue play, the disc must come back to the thrower unless 16.3 applies - this applies to both a completed pass, and a turnover.If the thrower is fouled before throw, but the foul continues to occur during throw, then 16.2 applies. If the foul occurs before the throw, but the thrower waits to call the foul during the act of throwing, 15.9 applies.

Unlike in previous version of the rules, continuation does not apply to calls made (not involving the thrower) during the act of throwing. So if a foul is called by the dump receiver while the thrower is in the act of throwing, play should stop immediately. If the thrower continues the throw, with no impact from the foul call, the result of the pass can stand as per 16.3. However if the thrower heard the foul call while they were throwing, and this impacted their throw and the pass was incomplete, 16.3 would not apply and therefore the disc would be returned to the thrower.Additionally if a pick is called while the thrower is in the act of throwing, and the thrower attempted to stop the throw as a result of the pick call, and the pass is incomplete, the disc would be returned to the thrower.
