On October 24th, 2011, following an exhaustive, four-year review of golf's 34 playing Rules, The R & A and the USGA announced that nine principal Rules have been amended to improve clarity and ensure penalties are proportionate. The principal changes are outlined in this section, with supporting decisions to help explain how the Rules changes will be applied in various situations.
Definition Change
The Definition is amended so that a player has addressed the ball simply by grounding his club immediately in front of or behind the ball, regardless of whether or not he has taken his stance. Therefore, the Rules generally no longer provide for a player addressing the ball in a hazard. (See also related change to Rule 18-2b).
If a player's approach to the ball or the act of taking his stance causes his ball to move, the player incurs a penalty stroke under R18-2a and the ball must be replaced. Otherwise no penalty is incurred.
Exerting Influence on Movement of Ball or Altering Physical Conditions
The Rule is amended to establish more clearly that, if a player intentionally takes an action to influence the movement of a ball or to alter physical conditions affecting the playing of a hole in a way that is not permitted by the Rules, R1-2 applies only when the action is not already covered in another Rule. For example, a player improving the lie of his ball is in breach of R13-2 and therefore that Rule would apply, whereas a player intentionally improving the lie of a fellow-competitor's ball is not a situation covered by R13-2 and, therefore, is governed by R 1-2.
Time of Starting
Rule 6-3a is amended to provide that the penalty for starting late, but within five minutes of the starting time, is reduced from disqualification to loss of the first hole in match play or two strokes at the first hole in stroke play. Previously this penalty reduction could be introduced as a condition of competition.
Seeing Ball; Searching for Ball
Rule 12-1 is reformatted for clarity. In addition, it is amended to (i) permit a player to search for his ball anywhere on the course when it may be covered by sand and to clarify that there is no penalty if the ball is moved in these circumstances, and (ii) apply a penalty of one stroke under Rule 18-2a if a player moves his ball in a hazard when searching for it when it is believed to be covered by loose impediments. This change means that the same Rules apply wherever a player is on the course when searching for a ball..
Ball in Hazard; Prohibited Actions
Exception 2 to Rule 13-4 is amended to permit a player to smooth sand or soil in a hazard at any time, including before playing from that hazard, provided it is for the sole purpose of caring for the course and Rule 13-2 is not breached.
Ball Moving After Address
A new Exception is added that exonerates the player from penalty if his ball moves after it has been addressed when it is known or virtually certain that he did not cause the ball to move. For example, if it is a gust of wind that moves the ball after it has been addressed, there is no penalty and the ball is played from its new position.
Ball in Motion Deflected or Stopped; By Outside Agency
The note is expanded to prescribe the various outcomes when a ball in motion has been deliberately deflected or stopped by an outside agency.
Playing from Wrong Place; Stroke Play
Note 3 is amended so that if a player is to be penalized for playing from a wrong place, in most cases the penalty will be limited to two strokes, even if another Rule has been breached prior to his making the stroke.
A new Appendix is added to prescribe general regulations for the design of devices and other equipment, such as tees, gloves and distance measuring devices.
