It is a foul when:
37. A ball touches a wall.

It is certainly a dead ball and a point awarded to the team that did not cause the ball to touch the wall. But, is that considered a foul? I think we're getting hung up on semantics, but I thought I would ask your opinions.

9-7-1 and 9-3-3-e.

Don't read too much into it, it'll make you go crazy...
