Nope, I'm gutted that BAR won the case.
However, there's a few factors to decide. Button has said (and let's not forget his management arn't that stupid lol) that he will be racing for Williams next year. He didn't say anything about winning or loosing the court case - so fingers crossed, he will be 'purchased' by Williams.
Dave Richards wouldn't want to 'stop' Button from leaving, but he would want to stop him from going for free! At least this way, Williams will have to 'break' the contract with a new agreement - likely, over a lot of cash!
My fingers are still crossed for Anthony Davidson, he's been incredible at BAR as third driver this season. He raced against Button from the ages of 9 years old, all the way through to european karting, where I also saw these two race Alonso, Raikonnen etc.
Dave Richards has said - if they lost the court case (or Button)...they will be racing Davidson.
Give Ant a season - he is better (definatly the potential to be) than Jenson.
