Question juridique clé
Whether the Federal Supreme Court may enter into the complaint despite non-payment of the advance costs within the granted grace period.
Solution extraite
No. Because the advance costs were neither paid in cash nor properly evidenced as paid within the non-extendable time limit, the Court could not examine the complaint.
Motifs extraits
The appellant did not comply with the payment order and the warning of non-entry under Art. 62(3) BGG. Under Art. 108(1)(a) BGG, non-compliance required summary non-entry.
