Kernrechtsfrage
Whether the Federal Supreme Court could hear the appeal under Art. 84 LTF despite the interlocutory nature of the decision.
Extrahierter Entscheid
Yes. The decision risked premature disclosure of secret information in a context functionally equivalent to mutual legal assistance, raising a point of principle and justifying immediate review.
Extrahierte Begründung
Premature transmission abroad can have effects similar to a final decision; the case also concerned a novel solution to prevent circumvention of mutual legal assistance rules.
