Formula One's international court of appeal will meet tomorrow to decide on the legality of the Brawn GP car that took Jenson Button to victory in the first two formula one races of the season.
Champions Ferrari, Red Bull, Renault and BMW-Sauber are united in appealing against stewards' decisions in Australia and Malaysia that the rear diffusers used by Brawn, Toyota and Williams are legal.
The double decker rear diffuser, channels the air cleanly under and out of the rear of car to create maximum downforce but rivals claim they break the spirit of the rules.
Brawn, who have been comfortably quickest in both races so far, and Toyota are currently first and second in the standings.
