Key legal question
Whether the criminal appeal is admissible despite non-payment of the advance on costs.
Extracted holding
The appeal is inadmissible because the required advance was not paid within the extended deadline.
Extracted reasoning
Under Art. 62 al. 3 LTF, failure to pay the advance within the additional period leads to inadmissibility; since this was manifest, simplified procedure applied under Art. 108 al. 1 let. a LTF.
