Question juridique clé
Whether the Federal Supreme Court could enter on the complaint despite non-payment of the court cost advance within the set deadline.
Solution extraite
No. Because the advance was neither paid in cash nor properly credited within the grace period, the court had to refuse entry.
Motifs extraits
After prior notice under Art. 62(3) BGG and warning of non-entry, the appellant still did not satisfy the advance-payment requirement or prove timely payment by debit confirmation. Non-entry therefore followed under Art. 108(1)(a) BGG.
