Question juridique clé
Whether the appeal could proceed despite non-payment of the required advance on costs.
Solution extraite
No. Because the advance on costs was not paid within the time limit, the Court would not enter into the appeal.
Motifs extraits
Under Art. 62 BGG, an advance on costs is generally required; no special reasons justified waiver, and the warning under Art. 62(3) BGG was ignored. Therefore non-entry followed under Art. 108 BGG.
