Question juridique clé
Whether the Federal Supreme Court could enter into the appeal despite non-payment of the cost advance after a grace period.
Solution extraite
No; the appeal had to be dismissed by non-entry because the appellant failed to pay the required advance even within the extended deadline.
Motifs extraits
Under Art. 62(3) BGG, non-payment of the advance after expiry of the set time limit permits non-entry in simplified procedure under Art. 108(1)(a) and (2) BGG.
