Question...
 

Following a held ball the official erroneously awards the ball to team A. While the ball is at the disposal of A1 the mistake is recognized. The official rules that the mistake cannot be corrected because it had to be discovered before the ball became live.

Is the official correct?

Let's Go To The Casebook ...
 

*6.4.1 SITUATION D: It is Team B’s turn for the next throw-in under the alternating-
possession procedure. By mistake, Team A is given that throw-in. Team A
(a) commits a throw-in violation, or (b) releases the ball on the alternating-possession
throw-in, but before the ball is legally touched inbounds, Team A or Team
B commits a foul. RULING: Once the throw-in ends – it is too late to change anything.
In (a), the throw-in ends when Team A violates and results in a throw-in for
Team B as well as the arrow for the next alternating possession. In (b), the alternating-
possession throw-in did not end when the foul occurred. Therefore, the
alternating-possession mistake is corrected and the arrow now favors Team B;
penalize the foul appropriately. (4-42-5; ; 6-4-4; 6-4-5)

Perfect...Thanks
