Question juridique clé
Whether the appeal could be entered into despite non-payment of the ordered advance costs.
Solution extraite
No. Because the appellant did not pay the advance costs even within the extended deadline, the court had to refuse entry on the appeal in simplified procedure.
Motifs extraits
Under Art. 62(3) BGG, failure to pay the ordered advance within the set grace period leads to non-entry; the conditions for summary non-entry under Art. 108(1)(a) and (2) BGG were met.
