What is goaltending and basket interference, and what is the penalty?

Question

Accepted Answer

Goaltending (Art. 31) happens when a player touches a shot: while it is completely above the level of the ring and on its downward flight to the basket, or after it has touched the backboard; or on a free throw, while it is in flight to the basket and before it touches the ring. Basket interference includes: touching the basket or backboard while the ball is in contact with the ring after a shot or the last free throw; reaching through the basket from below to touch the ball; a defender touching the ball or basket while the ball is within the basket; making the basket vibrate, or grasping it, so the ball bounces unnaturally or is helped in or kept out; grasping the basket and playing the ball.
