Questione giuridica chiave
Whether the appeal could be entertained despite non-payment of the required advance of costs within the extended deadline.
Decisione estratta
No. Because the appellant did not pay the advance of costs even within the non-extendable grace period, the Federal Supreme Court had to refuse entry on the appeal in summary proceedings.
Motivazione estratta
Under Art. 62 BGG, the appellant must pay an advance of costs; if it is not paid within the set time limit and grace period, the court does not enter on the filing. Service of the orders was deemed effected under Art. 44 Abs. 2 BGG.
