Questione giuridica chiave
Whether the mutual assistance request and provisional seizure were admissible in a fiscal matter
Decisione estratta
Mutual assistance was excluded because the case concerned a fiscal offence; the provisional measures had to be lifted.
Motivazione estratta
The Convention on laundering and confiscation does not create direct cooperation modes beyond domestic law and cannot override the statutory exclusion of mutual assistance for fiscal offences under Swiss law.
