## The wording

### Rule 4.3, part 1 of 30

Begins: “Defective serves are of three types and result in…”

- **20 June 1990, USHA Four-Wall Rules**: First recorded (automatic).

  > Defective serves are of three types and result in penalties as follows:

  Interpretations: 21 interpretations attached.
    - New here: The receiver standing in the center of the rear court, two to four feet from the back wall, should have a clear view of the served ball as it rebounds from the front wall when it is approximately five feet in front of the service zone.
    - New here: This is a difficult call because there will be instances in which the receiver will be screened, but the ball has been hit so high that it is going to result in a back-wall setup and the receiver will have time to get into a good position to attempt his shot.
    - New here: The screen serve, like any other hinder, is based on interference affecting the play.
    - New here: In the case just mentioned, there is initial interference, but the receiver still has time to get into good position so that the momentary screen will not affect the play.
    - New here: In such a case, the referee should not make his call too quickly, but should watch the reaction of the receiver.
    - New here: If the referee feels that the receiver hesitates getting into position, a screen should be called.
    - New here: If, however, the receiver moves quickly and obviously is going to have time to get into good position for a back-wall shot, the screen should not be called.
    - New here: The receiver should be given the benefit of any doubt so long as his receiving position is in the center of the court.
    - New here: However, if the receiver positions himself to one side of center or anticipates the serve is going to be hit to one side and moves in that direction too quickly, and the serve is hit to the opposite side, a screen should not be called.
    - New here: It is also important that the referee attempt to position himself in the middle of the balcony whenever possible so that he will have the same angle of view as the receiver.
    - New here: The best answer to this dilemma is: When in doubt, call a screen.
    - New here: Even though the foot fault occurs before the out serve, the out serve penalty takes precedence and shall be enforced.
    - New here: Another example: A server foot faults when contacting the ball and the ball does not hit the front wall first.
    - New here: Again, the out serve penalty should be enforced.
    - New here: For this reason, a referee should wait until after the ball is served to call a foot fault.
    - New here: In doubles, the server should not be called out if his partner intentionally catches the ball in self-defense.
    - New here: However, if the server's partner catches a served ball that otherwise would not have hit him, an out is the proper call.
    - New here: If the referee is doing a proper job, there should be no out-of-order serves.
    - New here: The referee should keep the players informed as to which player is the server.
    - New here: If the referee sees that a player is about to serve out of order, the referee should immediately stop the player from serving and inform the team as to which player should be the server.
    - New here: If, however, a player does serve out of order, the "out-of-order" rule shall apply.

### Rule 4.3, part 2 of 30

Begins: “The receiver should be given the benefit of any…”

- **1 April 2005, USHA One-Wall Rules**: First recorded (automatic).

  > The receiver should be given the benefit of any doubt so long as his/her receiving position is in the center of the court.

  Interpretations: 18 interpretations attached.
    - New here: Part 4, Rule 4.3 B.
    - New here: (1): Interpretation No. 5
    - New here: This is a difficult call because there will be instances in which the receiver will be hindered, but the ball has been hit so high that it is going to result in a setup and the receiver will have time to get into a good position to attempt his/her shot.
    - New here: The hinder serve, like any other hinder, is based on interference affecting the play.
    - New here: In the case just mentioned, there is initial interference, but the receiver still has time to get into good position so that the momentary hinder will not affect the play.
    - New here: In such a case, the referee should not make the call too quickly, but should watch the reaction of the receiver.
    - New here: If the referee feels that the receiver hesitates getting into position, a hinder should be called.
    - New here: If, however, the receiver moves quickly and obviously is going to have time to get into good position for a shot, the hinder should not be called.
    - New here: Part 4, Rule 4.3 D (3): Interpretation No. 6
    - New here: Even though the foot fault occurs before the out serve, the out serve penalty takes precedence and shall be enforced.
    - New here: Another example: A server foot faults when contacting the ball and the ball does not hit the wall first.
    - New here: Again, the out serve penalty should be enforced.
    - New here: For this reason, a referee should wait until after the ball is served to call a foot fault.
    - New here: Part 4, Rule 4.3 C (6): Interpretation No. 7
    - New here: If the referee is doing a proper job, there should be no out-of-order serves.
    - New here: The referee should keep the players informed as to which player is the server.
    - New here: If the referee sees that a player is about to serve out of order, the referee should immediately stop the player from serving and inform the team as to which player should be the server.
    - New here: If, however, a player does serve out of order, the "out-of-order" rule shall apply.

### Rule 4.3, part 9 of 30

Begins: “A legally served ball that travels between the legs…”

- **20 June 1990, USHA Four-Wall Rules**: First recorded (automatic).

  > A legally served ball that travels between the legs of the server is an automatic screen.

  Interpretations: 21 interpretations attached.
    - New here: The receiver standing in the center of the rear court, two to four feet from the back wall, should have a clear view of the served ball as it rebounds from the front wall when it is approximately five feet in front of the service zone.
    - New here: This is a difficult call because there will be instances in which the receiver will be screened, but the ball has been hit so high that it is going to result in a back-wall setup and the receiver will have time to get into a good position to attempt his shot.
    - New here: The screen serve, like any other hinder, is based on interference affecting the play.
    - New here: In the case just mentioned, there is initial interference, but the receiver still has time to get into good position so that the momentary screen will not affect the play.
    - New here: In such a case, the referee should not make his call too quickly, but should watch the reaction of the receiver.
    - New here: If the referee feels that the receiver hesitates getting into position, a screen should be called.
    - New here: If, however, the receiver moves quickly and obviously is going to have time to get into good position for a back-wall shot, the screen should not be called.
    - New here: The receiver should be given the benefit of any doubt so long as his receiving position is in the center of the court.
    - New here: However, if the receiver positions himself to one side of center or anticipates the serve is going to be hit to one side and moves in that direction too quickly, and the serve is hit to the opposite side, a screen should not be called.
    - New here: It is also important that the referee attempt to position himself in the middle of the balcony whenever possible so that he will have the same angle of view as the receiver.
    - New here: The best answer to this dilemma is: When in doubt, call a screen.
    - New here: Even though the foot fault occurs before the out serve, the out serve penalty takes precedence and shall be enforced.
    - New here: Another example: A server foot faults when contacting the ball and the ball does not hit the front wall first.
    - New here: Again, the out serve penalty should be enforced.
    - New here: For this reason, a referee should wait until after the ball is served to call a foot fault.
    - New here: In doubles, the server should not be called out if his partner intentionally catches the ball in self-defense.
    - New here: However, if the server's partner catches a served ball that otherwise would not have hit him, an out is the proper call.
    - New here: If the referee is doing a proper job, there should be no out-of-order serves.
    - New here: The referee should keep the players informed as to which player is the server.
    - New here: If the referee sees that a player is about to serve out of order, the referee should immediately stop the player from serving and inform the team as to which player should be the server.
    - New here: If, however, a player does serve out of order, the "out-of-order" rule shall apply.
