OMG...

Do Sauber have an in-house attorney? They really don't seem to have any kind of strategy for how to deal with this, besides hoping that they would win in court.

Now that they have lost, and exhausted every available appeal (AFAIK) what are their options besides letting GVdG drive? At some point they're going to have to get to grips with that reality. They signed a contract, and every court they have been in front of has told them that is in force. If they decide to ignore the various courts' conclusions, this is going to get *really* ugly in a hurry.
