The USGA and R&A announced on Tuesday a new ruling that will mitigate the influence of video review and revert to reliance on a player's integrity.

Fresh off the heels of a four-stroke penalty that cost Lexi Thompson the chance at a major at the LPGA's ANA Inspiration, Decision 34-3/10 means no penalty can be assessed  if a player has done “all that can be reasonably expected under the circumstances to make an accurate estimation or measurement … even if later shown to be wrong by other means (such as video technology).”

Thompson, leading the tournament by two strokes at the time, was penalized in the final round for playing a ball from an incorrect spot (two strokes) and signing an incorrect scorecard (another two) after a television viewer called in with information that the 22-year-old native of Coral Springs, Florida placed her ball on a putt incorrectly during the third round. Thompson would go on to lose the tournament in a playoff.

What remains unknown is how the major tours will handle scorecard infractions and viewer call-ins.

“This important first step provides officials with tools that can have a direct and positive impact on the game,” USGA executive director Mike Davis told the Golf Channel. “We recognize there is more work to be done. Advancements in video technology are enhancing the viewing experience for fans, but can also significantly affect the competition. We need to balance those advances with what is fair for all players when applying the rules.”

The rule is effective immediately.
