Key legal question
Whether the federal appeal had to be entered into despite non-payment of the court advance within the final deadline.
Extracted holding
No. Because the appellant did not pay the required advance or prove timely payment, the court did not enter into the appeal.
Extracted reasoning
After the request for an advance and a final non-extendable deadline under Art. 62(3) BGG, the appellant remained in default; therefore non-entry followed under Art. 108(1)(a) BGG.
