Ferrari have applied to a French court for an injunction against the proposed Formula One rule changes, according to the FIA president Max Mosley.
Ferrari are one of four teams who have threatened to withdraw at the end of this season unless fundamental revisions are made to the new regulations.
The Italian team, as well as Toyota, Red Bull and Renault, claim that an optional 40 million pound budget cap to be imposed for next year could create a two-tier world championship.
Mosley and F1 chief Bernie Ecclestone attended a meeting with team bosses at a Heathrow Airport hotel in London to discuss the current crisis.
At the end of the meeting no solution was agreed, with teams leaving to discuss alternatives.
