11) Sideline judges should call "foot fault" if the player makes contact with the sideline of the non-volley zone while or immediately after volleying the ball.

12) What should a line judge do when they see this situation, when the ball is contacted by the player before it bounces on the player's end?

18) In the picture, the server's left foot is touching the baseline when the server is starting his service motion. If he lifts his foot off the baseline just before serve contact, should the line judge call a fault?

25) Line judges may solicit opinions from players to determine a call.

26) When six line judges are used, the sideline judges are responsible for making line calls on their side of the net. However, each should watch the entire length of the sideline (baseline to baseline) in case the view of the sideline judge on the opposite end is blocked.

27) A delayed line call can raise suspicion of a line judge’s reliability.

28) The sideline judge is responsible for making sideline calls on the assigned sideline and service foot faults associated with the imaginary extension of that sideline.

29) A line judge should only focus on the edge of her assigned line. They should ignore all other action on the court.
