IAABO refresher #76

[Joel Poli]

A-1, who has the ball in the front court passes the ball toward A-2. B-2 bats the ball to the floor in A's frontcourt so it bounces toward the backcourt. A-1 runs into A's backcourt and catches the ball before it strikes the floor. The official rules this is a backcourt violation. Is the official correct?
I say yes.....

The catching by A-1 caused the ball to be in the backcourt?....violation...A-1 first to touch in the backcourt. Had A-1 let the ball touch in the backcourt..no violation..B-2 was the last to touch the ball once the ball had backcourt status.

I am in the minority at our rules meeting on this one.....help me see the light!
