LONDON, England (CNN) -- Ferrari have applied to a French court for an injunction against the proposed changes in Formula One, according to FIA president Max Mosley.
Ferrari have threatened to withdraw from F1 unless revisions are made to the new regulations.
Ferrari are among the teams who have threatened to withdraw from Formula One at the end of this season unless fundamental revisions are made to the new regulations.
Central to the argument is the claim that an optional £40 million ($60m) budget cap to be imposed for next year could create a two-tier F1.
At the moment, the big teams, such as Ferrari and McClaren, operate on annual budgets of $200 million to $300 million.
Teams might decide not to stick with the budget cap, but those that do will get technical freedom. Opponents say that will make the sport a two-tier competition and devalue it.
Mosley and F1 chief Bernie Ecclestone attended a meeting with team bosses at a Heathrow Airport hotel in London on Friday to discuss the crisis.
"During the meeting it became apparent that Ferrari have made an application to the French courts to apply for an injunction to stop us doing what we want to do," Mosley told waiting media.
"At the end of the meeting no solution was agreed, with teams leaving to discuss alternatives. It was a friendly meeting but the teams have gone off to see if they can come up with something better than the cost cap," added Mosley.
