Question juridique clé
Whether the appeal had to be entered into despite non-payment of the court advance within the extended time limit.
Solution extraite
No. Because the advance remained unpaid, the appeal could not be entered into under the simplified procedure.
Motifs extraits
The advance was not paid even during the grace period; therefore the conditions for non-entry were met under Art. 62(3) BGG and Art. 108(1)(a) BGG.
