Questione giuridica chiave
Whether the Federal Supreme Court could enter into the appeal despite non-payment of the advance within the grace period.
Decisione estratta
No. Because the advance was not paid even within the extended deadline, the court had to refuse entry into the appeal in summary procedure.
Motivazione estratta
Under Art. 62(3) BGG, failure to pay the required advance after a grace period permits non-entry; the court applied Art. 108(1)(a) BGG.
