_Penalty Throws._--A player wilfully fouled when within four yards of her opponents’ goal line shall be awarded a penalty throw, and the player who commits the offense must be ordered out of the water until a goal has been scored. The penalty throw shall be taken from any point on the four-yard line. In the case of a penalty throw it shall not be necessary for the ball to be handled by any other player before the goal can be scored, but any player within the four-yard line may intercept a penalty throw. _Note._--A player ordered out of the water for committing a wilful foul must remain out until a goal has been scored, notwithstanding that half-time may intervene or extra time be played, except by permission of the referee. _Declaring Fouls._--The referee or umpires shall declare a foul by blowing a whistle. The player nearest to where the foul occurred shall take the throw. The other players shall remain in their respective positions from the blowing of the whistle until the ball has left the hand of the player taking the throw. In the event of one or more players from each team committing a foul so nearly at the same moment as to make it impossible for the referee to distinguish who offended first, she shall have the ball out of the water and throw it in as nearly as possible at the place where the foul occurred in such a manner that one member of each team may have equal chance of playing the ball. In such cases the ball must be allowed to touch the water before it is handled and must be handled (i. e., played with the hand below the wrist) by more than one player before a goal can be scored. _Goal Keeper._--The goal keeper may stand to defend her goal, and must not throw the ball beyond half distance; the penalty for doing so shall be a free throw to the opposing side from half distance at either side of the field of play. She must keep within four yards of her own goal line or concede a free throw from the four-yard line to her nearest opponent. The goal keeper is exempt from clauses _a_, _c_, and _f_ in Rule for Ordinary Fouls, but she may be treated as any other player when in possession of the ball. Except when injury or illness compel her to leave the water, the goal keeper can only be changed at half time. _Goal Line Corner Throws._--A player throwing the ball over her own goal line shall concede a free corner throw to her opponents, and such free corner throw shall be taken by the player of the opposing side nearest the point where the ball leaves the field of play; if the attacking side throw the ball over, it shall be a free goal throw to their opponents’ goal keeper.
