The FIA International Court of Appeal (ICA) has rejected protests against the diffusers used by the Brawn, Toyota and Williams teams, after concluding that their ‘double decker’ designs comply with the 2009 regulations.

BMW Sauber, Ferrari, Red Bull and Renault had all questioned the legality of the diffusers, but following Tuesday’s hearing in Paris, the ICA decided that race stewards in Australia and Malaysia had made the right call in declaring them legal.

Full statement from the FIA:
The FIA International Court of Appeal has decided to deny the appeals submitted against decisions numbered 16 to 24 taken by the Panel of the Stewards on 26 March at the 2009 Grand Prix of Australia and counting towards the 2009 FIA Formula One World Championship.

Based on the arguments heard and evidence before it, the Court has concluded that the Stewards were correct to find that the cars in question comply with the applicable regulations.
