A Florida Court last week denied a music label attempt to force a US ISP to disclose the identities of 25 individuals accused of copyright infringement.
The Federal District Court denied the motion – backed by 16 record labels – to force ISP Bright House to give that information.
A local Orlando newspaper report said the court declared the labels had "improperly joined the 25 individuals, who had nothing in common other than their ISP, into a single lawsuit," the report says.
It said combining all the cases would cause "unreasonable prejudice and expense to the defendants", and inconvenience the court.
Electronic Frontier Federation legal director Cindy Cohn said: "Courts are beginning to recognize that the record companies crusade against filesharers is stepping on the privacy and due process rights of those accused."
