Question juridique clé
Whether the appeal must be entered into despite non-payment of the cost advance within the extended deadline.
Solution extraite
No. Because the advance was not paid even within the grace period, the Federal Court did not enter into the appeal.
Motifs extraits
Under Art. 62(3) BGG, failure to pay the required advance after being granted a deadline and grace period permits non-entry; the case was decided in simplified procedure under Art. 108(1)(a) BGG.
