The U.S. Supreme Court rejected the appeal of the man whose website was shut down by the Motion Picture Association of America (MPAA), which threatened his internet service provider with legal action. The MPAA issued an order to the ISP to unplug Michael Jay Rossi's Internetmovies.com because it said it had evidence that the site was distributing illegal copies of Return of the King. Lost on both the ISP and MPAA was the fact that Return of the King hadn't yet been completely made at the time. In fact, the site didn't allow movie downloads.
Lower federal courts held that the MPAA was not liable for damages because of a good faith clause in the relevant law, protecting companies that act in the belief that copyright violations are afoot.
Ignorance being a proper defense, the MPAA has now sailed through the complete federal court system unscathed.
