Throw-in question

[Dave9819]

Here is the scenario:

1. A1 releases the ball on a throw-in.
2. After A1 has released the ball, but before the ball crosses the in-bounds side of the throw-in boundary (i.e. the ball is still over the out-of-bounds), B1 contacts the ball.

I know if a teammate of A1 contacts the ball while standing in-bounds is a violation, has B1 violated in this case as well?

Plane restriction ends when the ball is released. B1 can then reach through plane and contact the ball. Legal.

ART. 10. . . The opponent(s) of the thrower shall not have any part of his/her
person through the inbounds side of the throw-in boundary-line plane until the
ball has been released on a throw-in pass.

NOTE: The thrower may penetrate the plane provided he/she does not touch the inbounds area or a player inbounds before the ball is released on the throw-in pass. The opponent in this situation may legally touch or grasp the ball.

Note the plane restrictions on the defense end when the ball is released on a throw in pass. If it's released on a pass between teammates standing OOB on an end line throw in, the restrictions are in place, and it is a violation.

............and if the pass between teammates is touched by the defense, it is a technical foul.

A decade ago, we discussed this one for a couple of years.

The Fed got tired of our arguing and edited 9-2-10, much to the satisfaction of those of us who were correct.
