Question juridique clé
Whether the Federal Supreme Court could enter into the appeal despite non-payment of the advance on costs.
Solution extraite
No. Because the advance was not paid within the set extended period and proof of timely payment was not provided, the appeal could not be heard.
Motifs extraits
After rejection of legal aid, the appellant neither paid the advance in cash at the Federal Court cashier nor at a post office for the court's credit, nor supplied the required debit confirmation; under the warning given, this led to non-entry under Art. 62(3) BGG and Art. 108(1)(a) BGG.
