Question juridique clé
Whether the Federal Supreme Court could enter into the complaint after the advance costs were paid late
Solution extraite
No. The advance costs were not paid within the non-extendable deadline, so the complaint had to be dismissed without entering into the merits.
Motifs extraits
The court had warned of non-entry under Art. 62(3) BGG. Since payment occurred after the deadline, the sanction under Art. 108(1)(a) BGG applied.
