What is required for a lawful block attempt?

For a block attempt to be lawful in volleyball, it is essential that the player does not touch the net during the execution of the block. Touching the net can result in a fault, which would give the opposing team a point or serve, depending on the situation. The integrity of the net is crucial, and any contact by the player while trying to block is considered a violation of the rules.

While it is also important to consider factors like player positioning and the action of the ball, the specific requirement that prohibits net contact is a fundamental rule that directly affects the legality of the block. Therefore, ensuring that players keep their hands and body away from the net while blocking is vital for maintaining fair play during the match.
