For all the years we've watched the RIAA's "sue 'em all" scorched earth legal campaign, they've only really won one case in court, and now that case has been declared a mistrial. A $220,000 penalty has also been thrown out, and defendant Jammie Thomas (who we've discussed previously) will now have a new trial. Of course this time around it may prove more difficult for the RIAA, given that the RIAA lawyers have to prove actual copyright infringement took place. Simply showing that Thomas made files available on the network (the RIAA's previous watermark for copyright infringement guilt) is not good enough.
