Whether the criminal appeal was admissible despite non-payment of the advance on costs within the supplementary deadline.
No. Because the appellant did not pay the requested advance of costs within the extended deadline, the appeal had to be declared inadmissible in simplified procedure.
Under Art. 62 LTF, failure to pay the requested advance after an additional deadline makes the appeal inadmissible; the deadline was not met within the meaning of Art. 48 al. 4 LTF, and summary dismissal under Art. 108 al. 1 let. a LTF was therefore warranted.
