Question juridique clé
Whether the appeal should be entertained after the appellant failed to pay the reduced cost advance by the deadline.
Solution extraite
The appeal could not be entered into because the appellant ignored the extended deadline after the advance was reduced.
Motifs extraits
The court had set a reduced advance and warned that failure to pay would lead to non-entry; no payment or further financial information was submitted within the grace period, so Art. 108 BGG applied.
