When outside interference occurs during a shot that has an effect on the outcome of that shot, the referee will restore the balls to the positions they had before the shot, and the shot will be replayed. If the interference had no effect on the shot, the referee will restore the disturbed balls and play will continue. If the balls cannot be restored to their original positions, the situation is handled like a stalemate.
