The US Supreme Court today ruled that Internet file-sharing services can be sued, notes a report from AP on the Washingto Post Web site. “The unanimous decision sends the case back to lower court, which had ruled in favor of file-sharing services Grokster Ltd. and StreamCast Networks Inc. on the grounds that the companies couldn’t be sued. The justices said there was enough evidence of unlawful intent for the case to go to trial.” Earlier today we noted that research firm Piper Jaffray has said that Apple would “would be the primary beneficiary” resulting from a US Supreme Court decision against peer-to-peer (P2P) file sharing.
