Key legal question
Whether the appeal had to be declared inadmissible because the cost advance was not paid within the extended deadline.
Extracted holding
Yes. Since the appellant did not pay the advance within the additional time limit, the appeal was declared inadmissible in summary procedure.
Extracted reasoning
Under Art. 62(3) LTF, failure to pay the required advance after warning leads to inadmissibility; the case was therefore handled under Art. 108(1)(a) and (2) LTF.
