Questione giuridica chiave
Whether the appeal could be entered into despite non-payment of the required advance on court costs.
Decisione estratta
No. Because the advance on costs was not paid even within the grace period, the court had to declare the appeal inadmissible in simplified proceedings.
Motivazione estratta
Under Art. 62(1) and (3) BGG, an advance on costs must be paid within the set period; if unpaid after a grace period, the Federal Supreme Court does not enter into the appeal.
