Questione giuridica chiave
Whether the appeal had to be entered into despite non-payment of the advance on costs.
Decisione estratta
No. Because the appellant neither paid the advance nor used the additional deadline, the Court declined to enter into the appeal.
Motivazione estratta
Under Art. 62 BGG, an advance on costs is required; if it is not paid within the additional deadline, the Federal Supreme Court may not enter into the filing.
