Despite being apparently unprepared to hear a case that many expected to raise its head at the opening round of the Formula One world championship in Melbourne, the FIA has wasted little time in arranging a date for the next stage of the ongoing diffuser row.

Initial protests against the parts fielded by Williams, Toyota and Brawn GP were thrown out by stewards at the Australian Grand Prix, prompting complainants Red Bull, Renault and Ferrari to lodge appeals against the decision. Those opposing the parts clearly had something to worry about after Nico Rosberg dominated the opening day at Albert Park for Williams, with both Toyota and 'newcomer' Brawn getting both their cars into the top seven, along with Kazuki Nakajima in the second FW31.

"The FIA's International Court of Appeal has received appeals from National Sporting Authorities in Austria, France and Italy on behalf of Red Bull Racing, ING Renault F1 Team and Scuderia Ferrari Marlboro against the stewards' decisions at the Grand Prix of Australia to reject the protests lodged regarding the diffusers used by some competitors," a brief notifying statement from the governing body confirmed.

"A hearing will be held in Paris on 14th April 2009 at 10.00 am (CET)."

The date, which falls between rounds two and three, means that the Formula One circus will go to Malaysia next weekend with the matter still unresolved.
