Question juridique clé
Whether the appeal should be entered into despite non-payment of the advance costs.
Solution extraite
No. Because the advance costs were not paid within the additional deadline, the appeal had to be declared inadmissible in simplified procedure.
Motifs extraits
The court had warned that failure to pay by 2014-01-27 would lead to inadmissibility. Since payment was not made, Art. 62(3) LTF required non-entry; the case could be decided under Art. 108(1)(a) and (2) LTF.
