When a defender makes contact with a thrower-in, the result is an intentional foul. Where A1’s arms are located (on the inbounds or out-of-bounds side of the boundary line) is immaterial for this penalty to be assessed. A1 is awarded two free throws and Team A awarded a throw-in at the spot nearest the foul. COMMENT: For a boundary plane violation warning to also be assessed, the defender must actually violate the rule and penetrate the boundary plane.
