IWBF Official Wheelchair Basketball Rules 2012 (1 December 2012)

36.1.3 To judge whether a foul is unsportsmanlike, the officials should apply the following principles:

• If a player is making no effort to play the ball and contact occurs, it is an unsportsmanlike foul.
• If a player, in an effort to play the ball, causes excessive contact (hard foul), it is an unsportsmanlike foul.
• If a defensive player causes contact with an opponent from behind or laterally in an attempt to stop a fast break and there is no opponent between the offensive player and the opponents’ basket, it is an unsportsmanlike foul.
• If a player commits a foul while making a legitimate effort to play the ball(normal play), it is not an unsportsmanlike foul.
