Welcome to my point: there’s no such thing. You always have to go through national courts, with reasons that sometimes defeat logic: if you hold copyright in several countries, you can pretty much pick and choose the legislature that is most advantageous to your case. Take this recent one: an Icelandic company sued an Icelandic artist for slander… In UK court. The “legal” basis was that the website was hosted on a .co.uk domain, but I’m sure that the strict UK slander laws and astronomical costs of its courts had nothing to do with it. Not a copyright case, I know, but I think it’s a good example of how laws and jurisdictions get fundamentally twisted when applied to the Internet. I think anyone can agree that it should’ve been settled in an Icelandic court.
