It's an absurd request. No country could issue such a document. For one thing, it would establish a precedent that the government could arbitrarily decide to overall any future decisions of the judiciary. For another, it would probably violate Sweden's treaty obligations.
That's well within the range of what a leader can do. Presidential pardon overrides the courts for one specific issue. And they could preemptively refuse to allow him to be extradited for the leaks by stating definitively that it was not a crime by their laws.
Presidential pardons are irrelevant as Sweden is not the USA, but in any case, the President cannot preemptively pardon people for future offenses for which they may or may not be convicted.
>And they could preemptively refuse to allow him to be extradited for the leaks by stating definitively that it was not a crime by their laws.
Who's "they"? Who is the person in Sweden who has the authority to override the courts and declare that someone isn't guilty of a crime in the absence of any proper legal process?
