“Last week’s court decision preventing the recording industry from forcing Internet service providers to identify their subscribers on peer-to-peer networks offers new hope to file traders who have been sued. But fighting the RIAA may prove costly for anyone hoping to challenge the trade group, which spends an estimated $17 million annually in legal fees. In the wake of Friday’s ruling, which found that the RIAA can’t subpoena Internet providers for subscribers’ personal information without going through the court system, experts say lawyers could feasibly argue that their clients’ information was unjustly obtained from ISPs, and therefore should not be used. But such a strategy would be unorthodox and difficult to carry out.”
