You must have 2 players to start or continue. Only interpretations of the rules may be protested. If a team protests to the Tournament Director they will be charged all of their remaining time outs. The Tournament Director will have the final decision on all matters. The Director may and will do whatever is necessary to finish the tournament, including shortening or changing the number of games, etc.
Substitution is permitted.
One additional player may be included on the team for substitution. Substitution is unlimited and unrestricted. However, the ball must still be clearly and cleanly hit. If the ball comes to a complete rest on the hand it is to be considered a lift and is a fault. Substitution is permitted.
