Questione giuridica chiave
Whether the federal appeal had to be entered into despite non-payment of the court advance within the extended deadline.
Decisione estratta
No. Because the advance was not paid and proof of timely payment was not filed, the court had to refuse entry into the appeal.
Motivazione estratta
The appellant ignored the final deadline under Art. 62(3) BGG, so non-entry followed under Art. 108(1)(a) BGG.
