The 2014–2015 edition of Decisions on the Rules of Golf contains 87 changes from the 2012–2013 book.

New revisions to the 2012–2013 edition of the Decisions on the Rules of Golf have been made, coming into effect January 1 for the 2014–2015 edition.

Announced by Golf Canada, in conjunction with the R&A and the United States Golf Association (USGA), the revisions are made every two years to ensure rules are constantly evolving and relevant to the game today.

The updated version contains more than 1200 entries addressing specific situations under the Rules of Golf. The book features 87 changes made from the 2012 version, including three new decisions, 59 revised ones, one renumbered, and 24 withdrawn.

There are four noteworthy decisions among the changes, according to the USGA website:

  • new decision 14-3/18, which confirms players can access reports on weather conditions on a smart phone during a round without breaching the rules;
  • new decision 18/4, which provides where enhanced technological evidence (e.g. high-definition television [HDTV], digital recording, or online visual media) shows a ball has left its position and come to rest in another location, the ball will not be deemed to have moved if that movement was not reasonably discernible to the naked eye at the time;
  • revised decision 25-2/0.5, which helps clarify when a golf ball is considered to be embedded in the ground through the use of illustrations; and
  • revised decision 27-2a/1.5, which allows a player to go forward up to approximately 46 m (50 y) without forfeiting his or her right to go back and play a provisional ball.
