All parliaments have some form of immunity to the law, they had to after Europe adopted/is increasing adopting a litigious state similar to that seen in the states. It it was simply revoked then politicians wouldn't be able to make certain difficult decisions without bringing personal interest into the equation. This seems to be a rock and a hard place scenario which will be at the very least quite interesting as it develops.
@ stoofa. Sweden has been huge on civil rights for several decades. The "Pirate" party's name is not literal, but jest (almost black humour) at the state of the anti piracy outfits operating there. It's not surprising that in such a nation there would quickly be a political presence after the anti-piracy groups have influenced the courts, provided incentive to officials and blackmailed citizens.
I should make it clear that the anti-piracy groups are private companies, not to be confused with the music industry.
Sadly there's an outfit operating the in uk (FACT) who're using similar tactics in their up and coming second case against a pair of forum admins. The problem is they are the ones running the case. They are providing the police with instructions, evidence and how to go about the "investigation". That is to say, the police haven't done anything, some private firm walked up to their door and started bossing them around. Their influence over enough powerful people in government means that they, not the police, are also holding all the (obviously totally impartial) "evidence". - Brief overview:

In short, the "pirate" isp is a response to the grey and downright illegal tactics certain companies have been using utilising similarly grey, but legal - subtle difference, practises to gain attention. Also the 1 download = 1 lost sale idea was a spin created by those same companies to bolster their cases. A spin which amusingly, congress asked them to prove and they quite obviously couldn't. If you buy a film then invite 10 friends around to watch it it's totally legal. If those same 10 friends got it via the interweb it's counted as 10 lost sales. Those same double standards have been present on both sides for years.
