It's the rule that shows that even when the NRL says they got the decision right, they actually got it wrong.
But it proves they were right about one thing: no matter what happened after referee Ben Cummins signalled six again someone was always going to be on the end of a wrong call.
It also shows the NRL might need to rip up the rule book with the rules governing trainers coming under fire.
While some trainers aren't meant to be on the field after the fourth tackle, medical trainers - which the Sydney Roosters' Travis Touma was - can.
That's why he was struck by the ball after Luke Keary's kick cannoned off Sia Soliola's head and into him - denying the Raiders a try-scoring opportunity in the third minute.
It's unclear whether the Roosters will be fined over the incident.
Rule 16.9, which governs when referees can change their calls, states once Cummins had signalled six again he can only change that decision due to foul play.
The NRL has already stated it is likely to review several rules during the off-season.
The governing body acknowledged the rule, but said it was written in a time which predates the two-referee system and television bunker.
"The referee judges on matters of fact and shall not subsequently alter those judgments," it said.
"He may cancel any decision made if prior foul play of which he had no knowledge is reported to him by a touch judge."
But Cummins changed his call from six again to the Raiders' final tackle mid play, after a Jack Wighton bomb bounced backwards off Bailey Simonsson's shoulder in a contest for the ball with Roosters fullback James Tedesco in the 71st minute.
Raiders hooker Josh Hodgson gathered the ball as Cummins waved six again, thinking it had come off Tedesco.
He then changed that call to last tackle on the advice of his fellow officials and Wighton was forced to hand the ball to the Roosters when he thought he had a fresh set of six.
While the six-again call might have been wrong, and would've meant the Roosters were on the end of a bad call, the rule clearly states this call can't be changed.
The Roosters were then incorrectly handed possession and scored the premiership-winning try off the next set.
It also means Raiders were dudded when a touch judge put his flag up and took it down again to allow Cronulla winger Sione Katoa to score a controversial match-winning try last season.
The Canberra Times can also reveal Touma started the game on the field and was there for the Roosters' entire first set and returned to the field as soon as their second began.
It was at the end of that second set that he was struck in the head.
The Roosters were given the scrum feed and a fresh set of six because it occured in their attacking half.
Raiders chief executive Don Furner described the rule under which that decision was made as outdated.
NRL guidelines state the medical trainers' role is to attend to injured players, provide water and on-field interchanges.
There were no Roosters players injured in the opening three minutes and they made their first interchange after 13.
The guidelines also state the trainer's presence can't "constitute a disadvantage to the opposing team", which it clearly did, and they face potential fines and breach notices for breaking them.
