When General Motors files for bankruptcy protection next week, a Dickensian tale of two legal processes will unfold. In one, a judge will be told that a new entity will emerge within three months with prized assets and a plan to revisit the best of times when GM was the world's largest carmaker. In the other, Bleak House comes to bankruptcy court as creditors shut out of the new entity will be told to argue for perhaps years about who gets company properties the new GM doesn't want.
