Which is NOT a principle for positioning on the court?

Remaining in one position is not a principle for positioning on the court because effective officiating requires referees to be dynamic and adaptable to the flow of the game. A stationary referee would be unable to maintain proper perspective on the plays occurring, which can vary significantly in speed and direction.

Positioning principles such as moving to the right spot, establishing an open angle, and always moving with a purpose emphasize the need for referees to constantly adjust their location for optimal visibility and decision-making. These principles ensure that referees can effectively observe the play, communicate with their partners, and maintain the integrity of the game. In contrast, being immobile would limit a referee's ability to make accurate calls and respond to the actions on the court.
