In the latest twist in Napster’s legal saga, an appeals court on Wednesday gave the online song-swapping company the go-ahead to allow legal music trading on its service.

The 9th U.S. Circuit Court of Appeals granted Napster’s request for a stay from a lower-court judge’s order one week ago that it remain shut down. Last Wednesday, federal Judge Marilyn Hall Patel of the U.S. District Court for the Northern District of California ordered Napster to remain offline until it could guarantee that it is successfully blocking 100 percent of all copyrighted music unauthorized for trading. Napster had told Patel that it could guarantee only a 99 percent success rate.
