Over and Back - Please help on this hard to find rule

[justjames]

Team A passes the ball into the front court to Player 1. Player 2 jumps from the backcourt toward the frontcourt and is in mid air when he receives a pass from Player 1 (who has both feet and the ball established in the frontcourt). Player 2 has not established himself in the frontcourt at all. Would this be considered a backcourt violation??? And, if so, where can I find this in the official rules?

This is in a High School setting. Thanks for your help!
