Key legal question
Whether the criminal appeal was admissible despite non-payment of the court cost advance.
Extracted holding
The appeal was inadmissible because the advance payment deadline expired without payment.
Extracted reasoning
After an additional deadline under Art. 62(3) LTF, accompanied by the warning of inadmissibility, the Federal Court received no payment; Art. 108(1)(a) LTF therefore required non-entry.
