Question juridique clé
Whether the appeal had to be declared inadmissible because the cost advance was not paid within the additional time limit.
Solution extraite
Yes. The appellant did not pay the CHF 1,000 advance of costs within the second deadline and did not show timely debit of the amount, so the appeal was inadmissible.
Motifs extraits
Under Art. 62 LTF, failure to pay the advance within the additional deadline leads to inadmissibility. That condition was met here, and the manifest inadmissibility allowed summary treatment under Art. 108(1)(a) LTF.
