Question juridique clé
Whether the Federal Supreme Court could enter the appeal despite non-payment of the advance costs within the extended deadline.
Solution extraite
No. Because the advance costs were not paid even during the extended deadline, the Court had to refuse entry in simplified proceedings.
Motifs extraits
Under Art. 62(1) BGG, failure to pay the ordered advance costs after warning of non-entry justifies non-entry under Art. 108 BGG.
