Key legal question
Whether the appeal in international mutual legal assistance was admissible as a particularly significant case
Extracted holding
Yes. The matter involved disclosure of information from the confidential sphere and raised an unresolved point of principle about spontaneous transmission of information without a Swiss investigation.
Extracted reasoning
Art. 84 BGG requires a particularly significant case; this was met because the Federal Supreme Court had not yet ruled on whether spontaneous transmission is lawful independently of a domestic criminal investigation.
