frontcourt backcourt violation

[Ted]

Situation 1: Player A1 has the ball in his/her backcourt. A1 passes the ball to A2 that has both feet in the front court. A2 jumps in the air, catches the ball and lands in the backcourt. Violation?
Situation 2: Team A is given the ball for a throw in at the midcourt line. Player A1 passes to player A2. Player A2 jumps in the air, from the front court, catches the ball and lands in the backcourt. I believe this is a violation in both cases but can't find it in the case book. Anyone have a thought here? Thanks!
