Mark Webber's victory in the Monaco Grand Prix was unchallenged on Sunday night, despite speculation over a potential protest from rival teams about the legality of his car.
It is understood that Ferrari, McLaren and Mercedes are unhappy that holes in the floor in front of the rear wheels of the RB8 do not comply with the regulations.
Other teams that are running such 'holes' have been forced to include slots that run out to the edge of the floor to ensure that they are openings - and not fully enclosed.
There was talk after the race that either McLaren or Ferrari were going to protest the result, but in the end neither team elected to take such action.
The official results were duly published at 6.45pm confirming Mark Webber's victory, and there was no subsequent challenge from any competitor about it.
However, both McLaren and Ferrari said afterwards that they were keen to get clarification on the matter before the next race in Canada.
Ferrari team principal Stefano Domenicali said: "I heard about that [the hole issue] in terms of discussion about this type of thing, and for sure we need a clarification on this point. That is all I can say tonight."
McLaren team principal Martin Whitmarsh said he was happy to follow the FIA's lead on the matter.
"It is not for me to comment on someone else's car, it is for the FIA to make that decision," he explained.
When asked if he expected the matter to be sorted out before the next race, he said: "Yes. I think it will be sorted out shortly."
Red Bull Racing boss Christian Horner insisted that his team had had full approval from the FIA on its design being legal.
"I would be disappointed if there would be a protest, it would not be particularly sporting," he said.
"We are totally happy that our car fully complies with the regulations. We have obviously consulted with the FIA over it - we have had their opinion in writing confirming the interpretation, so it would be disappointing if there was a protest. But we are entirely happy that the car completely complies."
