OBSTRUCTING OPPONENT'S VISION
"10.3.7 Situation A: Does holding a hand or hands in front of the face of a player who has the ball, by an opponent who is in a legal guarding position, constitute unsporting tactics? Ruling: Yes. The described action is illegal. It is unsporting for a guard to take a position behind a post player, or to take a postion facing an opponent, or to take a postion with his/her back to the ball and facing the opponent and then in either case, wave or hold hands in front of the opponent's eye's so that the opponent cannot see. Holding or waving hands near the eye for the ostensible purpose of obstructing an opponent's vision is unsporting. (10-3-7; 10-6-1)"
