Key legal question
Whether the federal appeal was admissible despite nonpayment of the ordered advance on costs within the deadline.
Extracted holding
The appeal was inadmissible because the required advance on costs was not paid within the time limit.
Extracted reasoning
The court noted that the advance of CHF 1,000 ordered on 21 December 2006 was not paid by 17 January 2007, so the appeal had to be declared inadmissible under Art. 150(4) OJ.
