Internet file-sharing services <A HREF="http://www.cnn.com/2005/LAW/06/27/scotus.file.sharing.ap/index.html">will be held responsible</A> if they intend for their customers to use software primarily to swap songs and movies illegally, the Supreme Court ruled Monday, rejecting warnings that the lawsuits will stunt growth of cool tech gadgets such as the next iPod. The unanimous decision sends the case back to lower court, which had ruled in favor of file-sharing services Grokster and StreamCast Networks 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.
