Rule 4. Safety
4.1. Introduction. The game of One-Wall Paddleball is such that there must be great concern for the safety of all of the participants. It is, therefore, imperative to exercise an extreme degree of caution at all times. Because of the potential for dangerous situations, this committee includes an entire section of safety rules and regulations, thereby demonstrating the importance we place on playing and conducting a safe Paddleball game. It is the intent of this safety section to discourage or eliminate any reckless or wild player from participating in this sport. Safety is a primary concern in this sport and will be considered as such in any judgments that may arise.

If, in the judgment of the referee, a striker has a reasonable view of his opponent, , and the opponent does not move into the area of the striker's swing, it shall be the striker's obligation at all such times to avoid hitting his opponent with the paddle. Failure to do so will result in one or more of the penalties listed in Rule 11, at the discretion of the referee.
4.4. Safety Block. A striker must call "block" whenever he believes there is danger of hitting his opponent in the course of a normal swing. Upon the "block" call the striker must refrain from hitting the ball. Any player hitting in a situation where there is an obvious potential for injury will be penalized at the discretion of the referee in accordance with the penalties listed in Rule 11. The player calling "block" must be in position to have returned the ball. The referee must then rule on the block call. If the referee confirms the call, the point will be replayed. If the referee denies the call, the player or side who made the call will lose a point or service.

If the official refuses, the head referee will inform the player that the appeal has been disallowed. Play will continue with no further discussion or comment. If the
official yields his/her call, the head referee may consult with one or more officials to reach a decision on the play.

Back to Rule 1.
Rule 14. Singles Service
14.1. One Serve. In tournament play, only one service is permitted. Any fault therefore, results in an out.
14.2. Defining major service area, minor service area, and automatic fault area. The position of the server's feet from the start to the conclusion of his/her serve shall divide the court into three areas: the major service area, the minor service area, and the automatic fault area.
Automatic Fault Area. The automatic fault area will be determined by drawing two imaginary lines perpendicular to the wall and parallel to the side lines which pass through the extreme right and left foot positions of the server.
If the server moves from his starting position to another point where the serve is completed, the entire area from start to finish will be an automatic fault area.
Major Service Area. The major service area of the court will be the larger of the two areas to either the left or right of the automatic fault area.
Minor Service Area. The minor service area of the court will be the smaller of the two areas to either the left or right of the automatic fault area. If, in the opinion of the referee, the server during his serve (from start to finish) creates two relatively equal areas on either side of the automatic fault area, both areas will be considered minor service areas.
14.3. The server has the option to serve to either the major or minor service area.
14.4. The server must designate to his opponent and the referee when serving to the minor serving area. This will be done by pointing to the minor service area. Violation will be a fault.
15. Limit on Appeals. (The tournament director may or may not invoke the following rule for any or all games in a tournament at his discretion.) Play must be continuous at all times and in accordance with the rules. Any pause in play to question or dispute a call by a linesperson or the referee shall be deemed an appeal, whether or not the appeal is made only to the referee as the rule stipulates. In a 15 point game, each side is limited to two appeals, and in a game of 21 or more points, each side is limited to three appeals. Once a side has exhausted their appeals, they may not halt play to question, dispute, or appeal any further calls in that game. Failure to abide by this rule will result in a penalty as outlined in Rule 11.
