Questione giuridica chiave
Whether the public-law appeal had to be declared inadmissible because the ordered advance costs were not paid in time.
Decisione estratta
Yes. Because the advance payment was not made within the prescribed period, the appeal could not be examined on the merits and had to be declared inadmissible.
Motivazione estratta
Under Art. 150 cpv. 4 OG, failure to pay the requested advance costs within the deadline leads to inadmissibility. The appellant's late pickup of the payment order did not help, since a litigant must expect judicial mail and service is deemed effected at the latest seven days after arrival at the post office. No timely request for extension or instalments was made.
