PDGA Rule 803.07 Interference
A. A thrown disc that hits another player, spectator, or animal shall be played where it comes to rest. A thrown disc that is intentionally deflected or was caught and moved shall be marked as close as possible to the point of contact, as determined by a majority of the group or an official. Alternatively, for intentional interference only, the thrower has the option of taking a re-throw. Players shall not stand or leave their equipment where interference with the flight or path of a disc could easily occur. The away player may require other players to mark their lies or move their equipment before making a throw if the player believes that either could interfere
with his or her throw.
B.
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.
