Question juridique clé
Whether the Federal Supreme Court could enter the bankruptcy appeal despite the unpaid cost advance
Solution extraite
No. Because the appellant neither paid nor properly proved payment of the advance within the final deadline, the appeal had to be dismissed as inadmissible.
Motifs extraits
After a warning under Art. 62(3) BGG and an unextended final deadline, failure to pay the advance triggers non-entry under Art. 108(1)(a) BGG.
