Ground Under Repair: is any part of the course so marked by order of the Committee or so declared by its authorised representative. All ground and any grass, bush, tree or other growing thing within the ground under repair are part of the ground under repair. Ground under repair includes material piled for removal and a hole made by a greenkeeper, even if not so marked. Grass cuttings and other material left on the course that have been abandoned and are not intended to be removed are not ground under repair unless so marked.
When the margin of ground under repair is defined by stakes, the stakes are inside the ground under repair, and the margin of the ground under repair is defined by the nearest outside points of the stakes at ground level. When both stakes and lines are used to indicate ground under repair, the stakes identify the ground under repair and the lines define the margin of the ground under repair. When the margin of ground under repair is defined by a line on the ground, the line itself is in the ground under repair. The margin of ground under repair extends vertically downwards but not upwards.
A ball is in ground under repair when it lies in or any part of it touches the ground under repair. 27
Stakes used to define the margin of or identify ground under repair are obstructions.
Note: The Committee may make a Local Rule prohibiting play from ground under repair or an environmentally-sensitive area defined as ground under repair.
Rule 25 - Abnormal Ground Conditions, Embedded Ball and Wrong Putting Green
Except when the ball is in a water hazard or a lateral water hazard, a player may take relief from interference by an abnormal ground condition as follows:
(i) Through the Green: If the ball lies through the green, the player must lift the ball and drop it, without penalty, within one club-length of and not nearer the hole than the nearest point of relief. The nearest point of relief must not be in a hazard or on a putting green. When the ball is dropped within one club-length of the nearest point of relief, the ball must first strike a part of the course at a spot that avoids interference by the condition and is not in a hazard and not on a putting green.
(ii) In a Bunker: If the ball is in a bunker, the player must lift the ball and drop it either:
(a) Without penalty, in accordance with Clause (i) above, except that the nearest point of relief must be in the bunker and the ball must be dropped in the bunker or, if complete relief is impossible, as near as possible to the spot where the ball lay, but not nearer the hole, on a part of the course in the bunker that affords maximum available relief from the condition; or
(b) Under penalty of one stroke, outside the bunker keeping the point where the ball lay directly between the hole and the spot on which the ball is dropped, with no limit to how far behind the bunker the ball may be dropped.
(iii) On the Putting Green: If the ball lies on the putting green, the player must lift the ball and place it, without penalty, at the nearest point of relief that is not in a hazard or, if complete relief is impossible, at the nearest position to where it lay that affords maximum available relief from the condition, but not nearer the hole and not in a hazard. The nearest point of relief or maximum available relief may be off the putting green.
(iv) On the Teeing Ground: If the ball lies on the teeing ground, the player must lift the ball and drop it, without penalty, in accordance with Clause (i) above.
The ball may be cleaned when lifted under Rule 25-1b. (Ball rolling to a position where there is interference by the condition from which relief was taken – see Rule 20-2c(v))
Exception: A player may not take relief under this Rule if (a) interference by anything other than an abnormal ground condition makes the stroke clearly impracticable or (b) interference by an abnormal ground condition would occur only through use of a clearly unreasonable stroke or an unnecessarily abnormal stance, swing or direction of play.
Note 1: If a ball is in a water hazard (including a lateral water hazard), the player is not entitled to relief, without penalty, from interference by an abnormal ground condition. The player must play the ball as it lies (unlessprohibited by Local Rule) or proceed under Rule 26-1.
Note 2: If a ball to be dropped or placed under this Rule is not immediately recoverable, another ball may be substituted.
In the above scenario a player has hit a ball which was seen to roll or land in an area marked by the committee as GUR. Once at the area the player and his partners are unable to find the ball. As the ball is not found the player will need to return to the the point where he last played from and play another ball as it has not been found and thus lost. (procced under lost ball rule 25-1(c) Some may argue that it is probably in the hazard, however as it is not known or virtually certain that the ball has entered the hazard the player can not play another ball in accordace with rule 26 (Water Hazards)
In the above scenario a player has hit a ball which was seen to roll or land in an area marked by the committee as GUR. Once at the area the player and his partners find the ball. The player shoud mark their ball and then may lift and clean their ball. The Player should then determine their nearest point of relief (x) and then drop their ball within 1 club length. Note that if the ball rolls back into GUR or if part of the ball is touching the line marking GUR they will need to re-drop.
