Re: @Sparty ... "arguably wrong"
"The court should have both taken judicial notice of the EU's resolution demanding his release without prejudice and the fact that the original Swedish warrant that commenced the whole problem was withdrawn."
If you receive a speeding ticket, then kick the officer's posterior in frustration and later have the ticket thrown out. You're still on the hook for the butt kicking. Failure to appear is a UK crime, not Swedish.
