Questione giuridica chiave
Whether the subsidary constitutional appeal is admissible despite non-payment of the court-cost advance within the additional deadline.
Decisione estratta
The appeal is inadmissible because the advance of costs was not paid within the prescribed time.
Motivazione estratta
Under Art. 62 al. 3 LTF, failure to pay the advance within the extended deadline leads to non-entry; the clerk’s notice confirmed non-payment and no timely debit confirmation.
