2nd Class -- R2 duties

[UMP 64]

In sit 2, if it is still on opponents side of the net and it is their 3rd hit, it is permissable to attack the ball before it breaks the plane of the net?

Ump64, no, even though the team had completed their attack, the ball can NEVER be attacked over the opponent's court. It can only be blocked over the opponent's court once the attack is considered to be complete.

In situation 2, the ball is over A's court and they have hit the ball 3 times, therefore their attack is considered to be complete. In this instance, B can reach over the net and block the ball before it gets to the net (in other words, while it is still over A's court) since A's attack is considered to be complete following their third hit. I hope that clears things up a little for you.
