[pop_ey]

What is answer to following?

A2 jumps from his/her frontcourt and taps A1’s throw-in into the backcourt. A1 is the first to touch the ball. Official rules it a backcourt violation. Correct Ruling?

Case 4.12.6 (b) seems to contradict with Case 9.9.1 Situation D and E.

4.12.6 SITUATION: During a throw-in by A1 from the end line by A’s basket (b) the throw-in is touched by A2 before it goes across the division line where it is recovered by A3. RULING: There is no a backcourt rule in effect in (b) during a throw-in. The throw-in ends in (b) when A2 legally touches the ball, but the backcourt count does not start until A3 gains control. (9-7, 8)

9.9.1 SITUATION E: A1 inbounds the ball at the division line; A2 jumps from thefrontcourt, controls the ball in the air, and while still in the air passes it to A3, who is in the backcourt. RULING: Backcourt violation. COMMENT: The throw-in exception only applies to the player initially receiving the throw-in pass (first touch).
