Question juridique clé
Whether the complaint had to be entered into despite failure to pay the court-cost advance within the extended deadline.
Solution extraite
No. Because the advance was not paid even within the statutory grace period, the Court had to decline to enter into the complaint under Art. 108 BGG.
Motifs extraits
The advance payment order was deemed served when the appellant failed to collect the postal delivery, since he must ensure receipt of court mail. After the first deadline expired, a formal grace period was granted with an explicit non-entry warning. As the advance still was not paid, the appeal could not be examined.
