Question juridique clé
Whether the federal complaint is admissible despite non-payment of the advance costs within the deadline.
Solution extraite
The complaint is not admissible because the required advance costs were neither paid in cash nor timely evidenced by a debiting confirmation within the non-extendable deadline.
Motifs extraits
After a warning under Art. 62(3) BGG, the complainant did not comply with the order to pay the advance costs or prove timely payment. Non-entry therefore follows under Art. 108(1)(a) BGG.
