What is the role of the line judge in signalizing plays at the net?

The primary role of the line judge at the net includes monitoring and signaling illegal plays, particularly those involving back-row players. This is essential since back-row players have specific restrictions during play regarding their positioning and actions, especially when it comes to attacking the ball. The line judge's responsibility to observe these plays helps ensure fair play and adherence to the rules, allowing for accurate officiating of the match.

While scoring indication and notifying teams of lineup changes are important aspects of officiating in volleyball, they fall within the purview of other officials. The referee generally manages scoring, while lineup changes are also under the referee's control and do not specifically pertain to the duties assigned to a line judge. Hence, focusing on signaling illegal plays made by back-row players aligns with the established role and responsibilities designated for line judges during a volleyball match. This specificity reinforces the understanding of each official's duties on the court.
