803.06 Optional Rethrow - Official Rules and Regulations of Disc Golf
At any time, a player may elect to rethrow from 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. The original throw plus one penalty throw are counted in the player's score.
If a disc at rest on the playing surface or supported by the target is moved, the disc shall be replaced as close as possible to its original location, as determined by a majority of the group or an official. If a marker disc is moved, the marker disc shall be replaced as close as possible to its original location, as determined by a majority of the group or an official. (If the two meter penalty is in effect See also 803.08 D and E for movement of a disc above the playing surface.)
Any player who consciously alters the course of a thrown disc, or consciously moves or obscures another player's thrown disc at rest or a marker disc, other than by the action of a competitively thrown disc or in the process of identification, shall receive two penalty throws, without a warning, if observed by any two players or an official.
