(1) Meaning of Interference by Abnormal Course Condition. Interference exists when any one of these is true:
The player’s ball touches or is in or on an abnormal course condition,
An abnormal course condition physically interferes with the player’s area of intended stance or area of intended swing, or
Only when the ball is on the putting green, an abnormal course condition on or off the putting green intervenes on the line of play.
If the abnormal course condition is close enough to distract the player but does not meet any of these requirements, there is no interference under this Rule.See Committee Procedures,
Section 8; Model Local Rule F-6 (the Committee may adopt a Local Rule denying relief from an abnormal course condition that only interferes with the area of intended stance).
