The first standard states, “the use of video technology can make it possible to identify things that could not be seen with the naked eye.” An example includes a player who unknowingly touches a few grains of sand in taking a backswing with a club in a bunker when making a stroke.
If the committee concludes that such facts could not reasonably have been seen with the naked eye and the player was not otherwise aware of the potential breach, the player will be deemed not to have breached the Rules, even when video technology shows otherwise. This is an extension of the provision on ball-at-rest-moved cases, which was introduced in 2014.
The second standard applies when a player determines a spot, point, position, line, area, distance or other location in applying the Rules, and recognizes that a player should not be held to the degree of precision that can sometimes be provided by video technology. Examples include determining the nearest point of relief or replacing a lifted ball.
So long as the player does what can reasonably be expected under the circumstances to make an accurate determination, the player’s reasonable judgment will be accepted, even if later shown to be inaccurate by the use of video evidence.
