TMO checks, explained properly.

The TMO helps the referee with certain reviewable moments, but the TMO does not replace the referee. What can be checked, and how far back the review can go, is controlled by the laws and protocols.

Quick ruling: the TMO can review specific incidents like tries and foul play, but the referee still owns the final decision on the field.
Decision path

How a TMO review works

  1. A possible reviewable incident happens, such as a grounding question, foul play, or a possible infringement before a try.
  2. The referee asks for help, or the TMO alerts the referee where protocol allows.
  3. Video is checked in the approved review window.
  4. The TMO gives evidence and recommendation.
  5. The referee announces the final decision.
What changes it

Details fans miss most

  • The TMO is not checking everything: only defined situations can be reviewed.
  • The review window matters: not every earlier phase can be pulled back into the check.
  • Evidence matters more than suspicion: a guess is not enough to overturn what happened live.
  • The referee still decides: even when the TMO supplies the key angles.
Common argument

"Why didn't they go back further?"

Because TMO protocols do not allow unlimited replay on every phase. Reviews stay within the parts of play the laws and competition rules allow officials to revisit.
