OBSTACLES AND RELIEF: 803.05
Significant changes here. A player is not allowed to move any obstacle on the course with the exception of casual obstacles to a stance listed below. A player is allowed to request that other people remove themselves and/or their belongings from the player's stance or line of play. This includes spectators, umbrellas, golf bags, chairs, etc…
Casual obstacles as in current rules – casual water, loose leaves or debris, broken branches no longer connected to a tree, motor vehicles, harmful insects or animals, players' equipment, people, or any item or area specifically designated by the director before the round – can be moved if they are in the player’s stance or run-up, even if part of the item like a branch is in front of the lie.
If the casual item can’t be moved, like water or a bee hive, the player may take free relief up to 5m back on the line of play like before. If players require additional relief beyond 5m, they may invoke either the new Optional Relief rule (803.05C) and go back on the line of play as far as they desire with a one-throw penalty. Or, decide to declare the Optional Rethrow discussed previously and return to their original lie and throw again with a one-throw penalty.
