4-2-1, 4-2-1a (NEW), 4-2-1e (NEW), 4-2-2(NEW) – In response to overwhelming support of the elimination of the solid-colored uniform requirements by officials and coaches this change establishes that the libero uniform must clearly contrast with his/her teammates’ uniforms. Additionally, the change clarifies the requirements for all legal uniforms and simplifies the requirements for the contrasting libero uniform maintaining the compliance of all currently compliant team and libero uniform jerseys.
4-2-4b – Eliminates the use of double zero (00) as a uniform number option in order to eliminate confusion surrounding the signaling of “00” and “0”. Additionally, many electronic scoring systems do not have “00” as a number option.
4-2-4c – Beginning with the 2023 season the body of the uniform number must clearly contrast with the uniform top regardless of borders or trim. This will eliminate the allowance of borders or trim to provide the only contrast between the number and the uniform. This change will assist in the identification of uniform numbers by officials and scorers.
5-5-1b, 5-6-1b, 7-1-1a, 7-1 PENALTIES 1, 7-1-2, 7-1-4 – In an effort to eliminate warmup interruptions by officials requesting rosters with 10 minutes remaining on the warmup clock this change requires the second referee to collect team rosters at the prematch conference while allowing changes to be made until 10 minutes remain on the pregame clock. Additionally, it establishes lineups to be submitted to the second referee before each set. This change allows for a smoother warmup process for coaches, players, officials and scorers.
5-9-2 NOTE – Establishes that the line judge shall take his/her position and move in line with the extension of the end line when the ball is being served near the line judge’s position replacing the old technique to move directly back in line with the sideline. This position adjustment allows the line judge to watch for foot contact with the end line and move quickly back for a view of the sideline. This is a more appropriate position and transition for line judges.
8-2-5g (NEW), 8-2-6d – Establishes that the ball remains dead when tossed for serve and it touches any part of the backboard or supports hanging in a vertical position over the serving area and is an illegal serve (Signal 13), not a service fault. This category change more accurately reflects the action since the ball is not contacted for serve.
