Questão jurídica principal
Whether the federal appeal had to be declared inadmissible because the advance on costs was not paid within the prescribed time.
Decisão extraída
Yes. The appellant neither paid the required advance nor submitted proof of payment, nor withdrew the appeal; inadmissibility followed under the summary procedure.
Fundamentação extraída
After the court ordered a CHF 2,000 advance under Art. 62(1) LTF and set an additional non-extendable deadline under Art. 62(3) LTF, the appellant remained inactive. Under Art. 108(1)(a) LTF, the appeal could therefore be dealt with summarily and declared inadmissible.
