Question juridique clé
Whether the appeal could be entered into despite non-payment of the advance on costs within the final deadline.
Solution extraite
No. Because the appellant failed to pay the required advance on costs even within the extended deadline, the court did not enter into the appeal under Art. 62(3) BGG and Art. 108 BGG.
Motifs extraits
The appellant was ordered to pay an advance of costs and received a grace period with a warning of non-entry. As payment still did not occur by the deadline, the statutory consequence of non-entry followed.
