Rules 18-2, 18-3 and 20-1 are modified as follows:

When a player’s ball lies on the putting green, there is no penalty if the ball or ball-marker is accidentally moved by the player, her partner, her opponent, or any of their caddies or equipment.  The moved ball or ball-marker must be replaced as provided in Rules 18-2, 18-3 and 20-1.

[this Local Rule applies only when the player’s ball or ball-marker lies on the putting green and any movement is accidental – not elsewhere]

A ball on the putting green moved as a result of wind, water, or some other natural cause such as the effects of gravity must be played as it lies from its new location.
