Question juridique clé
Whether the appeal had to be entered into despite non-payment of the required cost advance.
Solution extraite
No. In the absence of any special reasons justifying a waiver, the appellant failed to pay the ordered advance within the time limit and the grace period, so the appeal could not be heard.
Motifs extraits
Art. 62 BGG requires an advance payment of the likely court costs. The court had warned that failure to pay would lead to non-entry, and no special grounds for dispensing with the advance were shown. Under Art. 108 BGG, the court therefore issued a non-entry decision.
