Rule of the week:
A. After each throw, the thrown disc must be left where it came to rest until the lie is established by the placing of a marker. This can be done by placing a mini marker disc on the playing surface between the hole and the disc, directly in line with the hole, on the line of play, touching the thrown disc. A player may instead choose, without touching or repositioning the thrown disc, to use the thrown disc as the marker. The marker may not be moved until the throw is released. A marker inadvertently moved prior to the throw shall be returned to its correct location.
B. A player is only required to mark the lie with a mini marker disc when repositioning the lie under the rules. This includes the following rules: out-of-bounds, disc above or below the playing surface, lost disc, optional rethrow, relocated for relief, interference, or repositioning the lie within 1 meter of the out-of-bounds line.
C. If the thrown disc comes to rest in-bounds but within one meter of an out-of-bounds line, the lie may be relocated to any point on a one-meter line that extends perpendicularly from the nearest point on the out-of-bounds line, and passes through the center of the thrown disc. This holds true even if the direction takes the lie closer to the hole. See the following sections for other considerations in marking a thrown disc:
(1) Relocated for relief - 803.05 B, C
(2) Interference - 803.07 A, B
(3) Above or below the playing surface - 803.08 A, B
(4) Out-of-Bounds - 803.09 B
(5) Lost Disc- 803.11 B
D. 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.
E. If the thrown disc breaks and comes to rest in more than one piece, the largest piece, as
agreed to by a majority of the group or an official, is deemed to be the thrown disc.
F. 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.
G. A player shall receive a warning for the first violation of a marking rule if observed by
two or more players of the group or an official. One penalty throw shall be assessed for each
subsequent violation of any marking rule during the round if observed by two or more players of
the group or an official.
