New rules for volleyball

The Fédération Internationale de Volleyball (FIVB) has created new rules for the tournament to be held from 2025 to 2028.

Official Volleyball Rules 2025-2028

There are five main changes from the previous rules:

①Abolition of positional faults by the serving side
②サーブレシーブ側の動き出しタイミングの変更
③ボールアウトの明確化
④スクリーンの厳罰化
⑤ラリー中のチャレンジの廃止
⑥ダブルコンタクトの緩和(Test introduction at some tournaments only)

I will explain these in order.

①Abolition of positional faults by the serving side

Conventional：選手たちはサーバー以外、規定のポジション（ローテーション）に整列している必要があった。
New Rules:Players on the serving team other than the server can move and position themselves freely before the serve..
- Example: An outside hitter in position 2 (right front court) may be on the left side before the serve regardless of the positions of the other players.
the purpose: Smooths movement after receiving the serve, allowing for faster attacking.

Previously, players other than the server had to line up in a designated position, but from now on, only players on the serving team will be required to do so.You can freely take your position before servingHowever, the serve-receiving team must maintain the same rotational positional relationship as before.

②サーブレシーブ側の動き出しタイミングの変更

Conventional：サーブレシーブ側の選手は、相手のサーブヒット時から規定のポジション（ローテーション）を外れて動くことができた。
New Rules：サーブレシーブ側の選手は、相手サーバーのサーブトス後から動き出してよい。
the purpose：判断基準の明確化。

従来のルールではサーブヒット時に動き出してよかったですが、実際の運用は厳格ではなく判断基準があいまいでした。今回の改訂その判断基準をより明確にした形になります。これにより特に相手のジャンプサーブに対しては従来よりも柔軟なサーブレシーブフォーメーションを組みやすくなりました（通常ジャンプサーブはトスをしてからヒットまでの時間が長いため）。

③ボールアウトの明確化

Conventional: Even though the ball went outside the net (antenna), play continued at the umpire's discretion.
New Rules:The moment the ball passes outside the net (antenna) after the second or third touch, it is "out".
the purpose: Prevents protests and confusion by introducing clear criteria for assessment.

After the second or third touch, the ballThe moment you try to go to the other side of the net, you're out.However, after the first touch, the decision will be made as usual.

④スクリーンの厳罰化

Conventional: Although "screening," in which a teammate hides the ball while serving, was prohibited, it was effectively tolerated.
New Rules: If the umpire judges it to be an "intentional screen," there is a clear penalty of an immediate "loss of service point."
- Example: When front players are seen crowding together and spreading their arms to hide the server.
the purpose: Prevents cheating and ensures fairness in serve reception.

"Screening," which is the act of intentionally blocking the opponent's view when serving, has been prohibited for some time, but from now onIf the umpire judges it to be "intentional," the serve will be immediately forfeited.Especially when serving, the player on the serving sideRaising your hands above the top of your head is immediately considered an "intentional screen" and will result in a loss of points.It will be.

⑤ミッドラリー・チャレンジの廃止

Conventional:There was a "mid-rally challenge" system that allowed play to stop during a rally and request a challenge.
New Rules:You cannot apply for a challenge until the rally has ended..
the purpose: Preventing play interruptions and maintaining game flow.

The "challenge request during a rally" feature, which was previously introduced on a trial basis in some areas, has been abolished because it was thought to disrupt play.

In the future,The challenge can only be completed after the rally has finished.After a rally has ended, you can request a challenge for any play from the time you serve until the end of the rally.

⑥ダブルコンタクトの緩和（一部大会のみの試験導入）

ConventionalTouching the ball twice during the same movement (e.g. touching the ball twice with a fingertip) is considered "double contact" and is a foul.
New Rules:Allowed as long as the ball remains on the same team's side.
- Example: If the setter touches the ball twice when tossing it, it is OK as long as the ball is not passed to the opponent's court.
the purpose: Allows for fluid play without stopping rallies.

Even in situations that were previously considered double contact fouls,As long as the ball remains on your team's sideHowever, if the ball is touched twice in succession with clearly different movements, it will still be a double contact foul.

*This rule will be introduced on a trial basis in certain tournaments, such as VNL, with consideration given to making it a permanent rule once its effectiveness has been verified.
