Rule 6 Hinders

Historical rulebook: not the current rules. The current rules are here (USHA Four-Wall Rulebook, as of 26 January 2025).

While playing the game each player must give way to an opponent, and shall in no way interfere with the playing of the ball. Should the ball strike the server before reaching the opponent, or strike the opponent while in the act of being served, this shall be termed a hinder. Many of these might be deemed accidents, while again others might be intentional, and if so decided by the referee shall count as an ace against the player violating the rule, or a hand may be counted out.
