That's the whole point... no one WAS CERTAIN about the foul, NOT EVEN Jason (at least I can't see how he would be certain about hte shot if he fell off the shot)... so it should have been more appropriately handled by the tournament directer.
If nothing else, the directer could of made the ruling for Jason to throw the shot over again!
If someone would have notified the directer of the situation, this forum topic would have never been started. It was a contrevercial shot, and should have been more seriously considered than by just changing the score.
