Questão jurídica principal
Whether the appeal was admissible despite non-payment of the advance costs within the supplementary deadline.
Decisão extraída
No. Because the advance costs were not paid in time, the appeal could not be examined on the merits and had to be declared inadmissible.
Fundamentação extraída
Under Art. 62(3) LTF, failure to pay the advance costs after warning and supplementary deadline leads to inadmissibility; the case was therefore decided in summary procedure under Art. 108(1)(a) LTF.
