Central to Rossi's defence, and taken into account as 'provocation' by Race Direction, is the claim that Marquez was deliberately holding up Rossi to spoil his race and title chances.
That was also the accusation made against Marquez by Rossi on Thursday, after reviewing the previous Phillip Island race.
On Sunday evening, Rossi said: “In every braking he overtake me, slow down a lot in the corners and for me he didn't open the throttle on the straights.”
Marquez rejected the allegation: “I tried to push in the beginning. I did a [2m] 0.8s. Then I made a mistake at Turn 4, where I'd been struggling all weekend. And then even though we [Marquez and Rossi] overtake many times we were riding fast, in 2m 1.9s.
“When he [Rossi] overtake me the first time, I tried to follow him, but then I saw I can be faster and then I tried to do my race.
“Of course Valentino was disturbing me and I was disturbing Valentino [during the passes], because we couldn't find the best pace. When Valentino was in front he was not very fast and after this incident, his lap time was 2m 1s-high, 2m 2s-low and I thought that I was able to ride even faster.”
Mamola's impression was that the pace of Marquez and Rossi was not suspiciously slow:
“Even with those guys passing each other the way they were, they were doing 2m 1.9s, which is still quite a fast race pace. Would Valentino have been able to close on Jorge [without the Marquez battle]? Nobody knows.
“Was Marc trying to slow in some corners? I don't think so. There were sections where Valentino was clearly faster and there were sections where he could not pull away [from Marquez].
“The only way you can do it is like in F1, by bringing up the telemetry: 'Did you brake in the same zone? Did you stop the bike?'”
Marquez and Rossi passed each other nine times on lap 5 alone, is that proof of something unusual?
“Should Marc just pull over and let Valentino go? I think there was a lot of 'clouds' above both riders [after what had been said earlier in the weekend] 'I'll do this and you do that' type of thing. That's my belief.”
Mamola also saw no reason to doubt that the mistake by Marquez, which allowed Lorenzo to take over second place, was genuine.
“He picked up the back [wheel]. How many times have we seen Marc nearly crash during the season? So would you say that he could have nearly crashed trying to follow Dani into Turn 4? I would say yes.
“At the beginning of the race, trying to stay with Dani, he makes an error and everyone says 'oh, but he seemed to just let him go by'. But if he's on the kerb and nearly onto the grass - and Jorge is not a slow guy. Jorge is there for blood; to win at the beginning of the race and do his style of race.”
Mamola concluded: “No-one's going to be satisfied with the end result today. We're all up in arms because what we had in Australia was something very beautiful.”
Rossi was given three Penalty Points by Race Direction, meaning he will start the Valencia title showdown from last on the grid. The Italian has a seven point advantage over team-mate Lorenzo.
