Question juridique clé
Whether the appeal had to be dismissed because the court advance was not paid within the deadline.
Solution extraite
The appeal could not be examined and was not entered into because the required advance was not paid on time.
Motifs extraits
Under Art. 62(3) BGG, failure to pay the ordered advance within the non-extendable deadline leads to non-entry; the case was therefore decided in simplified procedure under Art. 108(1)(a) and (2) BGG.
