802.01 Teeing Off
Play begins on each hole with the player throwing from within the teeing area. When the disc is released, the player must have at least one supporting point in contact with the surface of the teeing area, and all supporting points must be in contact only with the surface of the teeing area. Supporting point contact outside the teeing area is allowed if it comes before or after, and not at, the moment the disc is released.
Any supporting point contact outside the teeing area at the time of release constitutes a stance violation and shall be handled in accordance with sections 802.04 E and F.
