A disc is out-of-bounds if its position is clearly and completely surrounded by an out-of-bounds area. See 802.02.B for determining when a disc in water or foliage has come to rest.
The out-of-bounds line is part of the out-of-bounds area.
A disc that cannot be found is considered to be out-of bounds if there is reasonable evidence that the disc came to rest within an out-of-bounds area. In the absence of such evidence, the disc is considered lost and play proceeds according to rule 804.05.
A player whose disc is out-of-bounds shall receive one penalty throw. The player may elect to play the next throw from:
The previous lie; or,
A lie that is up to one meter away from and perpendicular to the point where the disc last crossed into out-of-bounds, even if the direction takes the lie closer to the target; or,
Within the designated drop zone, if provided.
Those options may be limited by the Director as a special condition only by prior approval of the PDGA Tour Manager.
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, the one-meter relief may be taken from a point upward or downward along the vertical plane.
If the thrower moves the disc before a determination regarding its out-of-bounds status has been made, the disc shall be considered out-of-bounds.
