When a throw-in is taken on the end line in the frontcourt, who should blow the whistle before the throw-in?

When a throw-in is taken on the end line in the frontcourt, it is the responsibility of the active referee to blow the whistle before the throw-in is executed. This action serves as an official signal that the play is ready to resume, helping to maintain the flow of the game and ensuring that all players are prepared for the upcoming action.

The active referee is the one overseeing the play at that moment, monitoring player positioning and ensuring compliance with the rules. By blowing the whistle, they affirm that everything is in order and signal to the player taking the throw-in to proceed. This emphasizes the referee's role in managing the game and maintaining order on the court.

Other choices do not align with the protocol established in FIBA rules. The non-active referee is not in charge of immediately signaling for the throw-in, as their focus is on other aspects of the game or monitoring the overall court dynamics. While both referees work as a team to officiate the game effectively, only the active referee has the authority to give the signal for the throw-in in this scenario. Allowing the player to initiate the throw-in without a whistle could lead to confusion about whether play has officially resumed.
