Question juridique clé
Whether the appeal could be entered into despite non-payment of the required advance costs within the extended deadline.
Solution extraite
No. Because the advance costs were not paid even after the grace period, the Court could not enter into the appeal.
Motifs extraits
Under Art. 62(3) BGG, failure to pay the advance costs within the set period, including the additional deadline, leads to non-entry in the simplified procedure under Art. 108(1)(a) BGG.
