Question juridique clé
Whether the appeal had to be entered into despite non-payment of the cost advance.
Solution extraite
No. Because the appellant failed to pay the ordered cost advance even within the extended deadline, the court had to decline to enter into the appeal.
Motifs extraits
Under Art. 62 BGG, the appellant must pay an advance for expected court costs. If the advance is not paid within the set time limit and the additional grace period, the Federal Supreme Court does not enter into the filing.
