Question juridique clé
Whether the appeal could be entered into despite non-payment of the ordered cost advance within the grace period.
Solution extraite
No entry could be made because the appellant did not pay the advance within the prescribed period or the grace period.
Motifs extraits
Under Art. 62 BGG, an appellant must pay the anticipated court costs as an advance. If the advance is not paid by the deadline and the grace period expires unused, the Federal Court does not enter into the appeal; the simplified procedure under Art. 108 BGG applies.
