803.09 Out-of-Bounds

A. A disc shall be considered out-of-bounds only when it comes to rest and it is clearly and
completely surrounded by the out-of-bounds area. A disc thrown in water shall be deemed to be
at rest once it is floating or is moving only by the action of the water or the wind on the
water. See section 803.03 F. The out-of-bounds line itself is considered out-of --bounds.   In order to
consider the disc as out-of bounds, there must be reasonable evidence that the disc came to rest within the out-of-bounds area.  In the absence of such evidence, the disc will be considered lost and the player will proceed according to rule 803.11B.

B. A player whose disc is considered out-of-bounds shall receive one penalty throw. The player may elect to play the next shot from:
(1) The previous lie as evidenced by the marker disc or, if the marker disc has been moved from an approximate lie, as agreed to by the majority of the group or an official; or (2) A lie that is up to one meter away from and perpendicular to the point where the disc last crossed into out-of-bounds, as determined by a majority of the group or an official. This holds true even if the direction takes the
lie closer to the hole; or (3) Within the designated Drop Zone, if provided.  These options may be limited by the tournament director as a special condition (see 804.01).

C. The Rule of Verticality. The out-of-bounds line represents a vertical plane. Where a player's
lie is marked from a particular point within one meter of the out-of-bounds line pursuant to
the rules, the one-meter relief may be taken from the particular point upward or downward along
the vertical plane.

D. If the in-bounds status of a disc is uncertain, either a majority of the group or an
official shall make the determination. If the thrower moves the disc before a determination has
been made, the disc shall be considered out-of-bounds, and he or she shall proceed in
accordance with 803.09 B counting all throws made prior to the determination of the in-bounds status of the original lie. If a player other than the thrower moves the disc before a
determination has been made, the disc shall be considered in-bounds, and play for the thrower
and the mover of the disc shall proceed under the rules of interference, 803.07 B and C.
