Question juridique clé
Whether the federal appeal had to be declared inadmissible because the advance on costs was not paid in time.
Solution extraite
Yes. The appellant failed to pay the advance costs within the additional deadline, so the appeal was inadmissible under Art. 62(3) BGG and the simplified procedure applied.
Motifs extraits
After the rejected request for instalment payments and the further extension of time, the appellant still did not pay. He had to expect a judicial communication and had taken no measures to secure delivery, so he bears the consequences of non-receipt of the final order.
