With the proposed new Rules due to take effect from 1 January 2019, The R&A can confirm that there will be no change to the Decisions on the Rules of Golf publication for 2018.
The current publication, titled, ‘Decisions on the Rules of Golf, 2016 – 2017’ will continue to be valid through to the end of 2018 until the new Rules of Golf take effect on 1 January 2019.
This current Decisions publication continues to be available both as a printed book from most major booksellers, from the R&A Shop and as an App from the links below.
The R&A and USGA issued a new Decision, on 25 April 2017 - Decision 34-3/10. This new Decision limits the use of video evidence and further details can be found here.
It is worth nothing that as the Decisions book will not be reprinted for 2018, Decision 34-3/10 is not included in the current version of the printed book. The Decisions Apps, have however been updated to reflect this new Decision.
