When a player is found by the umpire to have delivered the ball contrary to those rules, the umpire will call a "no-ball" and he is said to have been "called for throwing". Where public opinion is that a player's bowling action appears to be that he routinely throws, he is said to have a "suspect" or an "illegal" action, or more derogatorily, he is said to be a "chucker". The issue is often highly emotive with accusers considering that deliveries with an illegal action are akin to cheating.
