Ferrari is to go to the French courts where it will take out an injunction against the FIA's proposed rule changes.

The news comes following today's meeting in London between the teams, the FIA and Bernie Ecclestone.

Ferrari's action indicates that not only is the matter far from being resolved but that the meeting did not go well in terms of the Italian team and the FIA resolving their differences.

Revealing Ferrari's surprise move, Mosley told reporters, following today's meeting: "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."

Referring to the injunction, which he was advised about by text message during the meeting, Mosley added: "When people start bringing proceedings it gets very difficult to negotiate with them.

"It was a friendly meeting," he added, "but the teams have gone off to see if they can come up with something better than the cost cap."

It is understood that Ferrari's case, which if successful will be appealed by the FIA, will be heard in Paris on Tuesday.
