If they can't prove any of this stuff they wouldn't file the suit. No matter what you or I think of Apple, the chances that this went down at least as criminally as they allege, are very high.

> To hide the truth, Vice-President of Finance, Alex Roman, outright lied under oath. Internally, Phillip Schiller had advocated that Apple comply with the Injunction, but Tim Cook ignored Schiller and instead allowed Chief Financial Officer Luca Maestri and his finance team to convince him otherwise.

The Court refers the matter to the United States Attorney for the Northern District of California to investigate whether criminal contempt proceedings are appropriate.
