Questione giuridica chiave
Whether the complaint was timely under the rules on filing from abroad.
Decisione estratta
The complaint was late because the decisive act had not been shown to reach a Swiss post office within the deadline.
Motivazione estratta
For writings under the Debt Enforcement and Bankruptcy Act, timely filing requires delivery to the authority or a Swiss post office by the last day of the deadline. Mere entry into Swiss territory does not suffice.
