At what point does officials' jurisdiction begin?

Officials' jurisdiction begins when the officials enter the court. This means they have the authority to enforce the rules and maintain order at that point. When officials step onto the court, they take responsibility for the game environment, including interactions with players and coaches and ensuring that the pre-game protocols are followed. This jurisdiction remains until the officials leave the playing area after the game has concluded.

The options that suggest the game officially starts or when the referee arrives at the venue do not account for the officials’ management of situations leading up to the game, such as monitoring warm-ups and ensuring compliance with any pre-game procedures. Simply arriving at the venue does not grant them authority; it's their presence on the court that is pivotal. The scenario of teams arriving also does not establish jurisdiction, as it solely pertains to the players and has no bearing on the officials' responsibilities until they are on the court. Therefore, the critical point of jurisdiction is indeed when the officials enter the court.
