Four teams have now lodged protests against the legality of the rear diffusers fitted to the Brawn, Toyota and Williams cars.
The news emerged in the Albert Park paddock on Thursday after the controversial aerodynamic components were declared legal by FIA scrutineers ahead of the 2009 season opener.
"There are different interpretations of the rules, and we need clarity as quickly as possible," BMW-Sauber team boss Mario Theissen said.
Ferrari, Renault and Red Bull also protested, and it is understood they are protesting against all three teams.
The stewards are due to consider the protest on Thursday, but depending on the outcome either the protesting teams, or the three diffuser teams, are expected to send the matter to the Court of Appeal.
If the stewards side with the protesting teams, Brawn, Toyota and Williams will be permitted to race under appeal.
FIA president Max Mosley has already revealed that the appeal would not be able to be heard until after next Sunday's Malaysian grand prix.
