Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the required advance on costs
Extrahierter Entscheid
No; the appeal was declared inadmissible because the advance on costs was not paid or credited within the deadline.
Extrahierte Begründung
The advance on costs remained unpaid after the initial and supplementary deadlines, so the Federal Tribunal could not examine the merits under Arts. 48(4) and 62(3) LTF; the case was decided in simplified procedure under Art. 108(1)(a) LTF.
