THE RULING: A federal judge again ordered the release of a letter that Facebook says can help prove that a man's lawsuit claiming half ownership of the multibillion-dollar company is a fraud.

THE FINES: The judge also fined the man and his attorney for not giving the letter to Facebook's lawyers when told to twice before.

THE LETTER: Facebook says the letter from the Kasowitz, Benson, Torres & Friedman law firm informs two other law firms that once represented the man, Paul Ceglia, that it is withdrawing from the case based on a finding that the contract is a fake.
