BBC commentators Martin Brundle and David Coulthard believe Fernando Alonso was the one who complained to race stewards about Lewis Hamilton's weaving at the Malaysian Grand Prix.
The two were battling it out for the final podium spot when Alonso mistimed an overtaking move and his Ferrari made contact with the back of the MP4-26.
Everyone dismissed the collision as a racing incident as stewards made no comment about it during the closing stages of the race. However, the duo were summoned at the completion of the race and Alonso was punished for causing the accident while Hamilton was slapped with a 20-second penalty for making more than one move to defend his position.
Writing in his Telegraph column, Coulthard says he didn't see anything untoward about Hamilton's defending and believes Alonso and Ferrari raised alarm about the incident.
"I had not seen any weaving myself, but that is not to say it did not happen," he wrote. "In the commentary box we rely on the international feed and unless the director or a cameraman sees an incident, it is not broadcast.
"The race director, Charlie Whiting, obviously did not spot it at the time, or did not deem it worthy of investigation. So clearly Ferrari and Fernando raised the issue when he went to see the stewards about the collision."
He added: "It seems a fair assumption that Fernando only reported Lewis's weaving since he was already in trouble himself.
"But that does not make his complaint any less valid. And once reported, the stewards have an obligation to uphold the rules."
Brundle echoed Coulthard's point and called for consistency from the stewards.
"We did not see anything in the commentary box that raised alarms but the stewards have access to far more footage and data than we do and I suspect they want to set a precedent in this new style of F1 racing," he wrote in his BBC Sport blog.
"The problem is that there will be four different stewards this weekend in China and there needs to be consistency in any decision-making.
"For example, there will be comparisons between what Hamilton did in Sepang and the tactics Felipe Massa adopted in Australia, as well as Vettel's defensive manouevres going into the first corner.
"We did not hear about Hamilton's potential penalty during the race because the issue was only raised by Alonso and Ferrari afterwards.
"Alonso was also penalised 20 seconds after running into the back of Hamilton but, given he did not damage the Briton's race at that point, I would have thought having to pit for a new nose was penalty enough."
