I have no idea who is right and know very little about either party in this case. But I do have some knowledge of the law of Scandinavia and Dan Koehl lives in Sweden. They can do all the suing they want in USA. As long as Dan Koehl doesn't live there and doesn't have an economic interest in the country (e.g. a firm with departments in USA), it won't mean much. In the same way it won't mean much if an average American is sued in Sweden (or Germany, or Australia, Mexico, China... etc). Sure the US court may order blogspot (registered in the USA) to remove his account, but there are plenty of other blogs out there. Additionally, google, the owner of blogspot, have been quite fierce in their fight against what potentially could be perceived as attempts of limiting free speech. Alternatively PAWS can sue him in Sweden, in which case a Boston law firm will be of little use, and even if they win, the damages are tiny compared to the wild sums sometimes paid in damages in the USA. If PAWS won a defamatory case like this, it is unlike the sum would be above 3x average monthly salary in Sweden, and it would likely only be a fraction of that. In general, Europe has a very different approach to suing than the USA.
