Question juridique clé
Whether the appeal had to be entered into despite non-payment of the advance costs
Solution extraite
No. Because the advance payment was not made within the original deadline or the grace period, the appeal was not entered into under the simplified procedure.
Motifs extraits
After proper service of the order and the subsequent grace-period order, the appellant still did not pay the required advance; under Art. 62(3) BGG this leads to non-entry for manifest inadmissibility, decided in the simplified procedure under Art. 108 BGG.
