Link to the appeal's court ruling? San Francisco court I assume will have it up very quickly, but I'm not sure where to look. Usually people have legal documents posted on Scribd very quickly, but my compulsory search found nothing under "naruto v slater" today
Those links are to the complaint and the district court's order dismissing the case.
Edit: See above for link to LA Times article reporting that a settlement was reached between PETA and Slater, not that the Ninth Circuit issued an opinion.
