</ref> The decision to call on the video referee (now called "Television Match Official (TMO)") is made by the referee following discussion with the assistant referees/touch judges and cannot be instigated by the players or coaches of either team. When concerning an act of foul play, the TMO may alert the referee and initiate the replay process.

In a possible try/no try situation, the referee shall signal his initial on-field decision (the "soft signal") and request the TMO to review all available footage and provide "<u>advice</u> and recommendations" to the on field referee. The referee should only change their decision where there is "clear and obvious" evidence that it was incorrect.<ref>{{Cite web|url=https://www.rugbyworld.com/tournaments/six-nations-2022/tmo-television-match-official-explained-88934|title = TMO – television match official explained in a handy guide|date = 9 February 2020}}</ref> In stadia with screens, the TMO may show footage directly to the referee.<ref>{{cite web|title=TMO Global Trial Protocol Aug 2019|url=https://resources.world.rugby/worldrugby/document/2021/02/20/9a177ed0-b2e4-4185-bf7b-370c782e5a03/TMO_Trial_From_August_2019_EN.pdf|access-date=25 February 2021|website=World Rugby}}</ref> As per Law 6.5 A of the Laws of Rugby Union, "The referee is the sole judge of fact and of law during a match".<ref>{{Cite web|last=worldrugby.org|title=Laws of the Game {{!}} World Rugby Laws|url=https://www.world.rugby/the-game/laws/law/6|access-date=2021-02-25|website=www.world.rugby}}</ref> Once a final decision is made, it is to be signaled by the referee.
