Questão jurídica principal
Whether the appeal was admissible despite non-payment of the ordered cost advance within the additional time limit.
Decisão extraída
The appeal was not admitted because the required cost advance was not paid within the set grace period.
Fundamentação extraída
Under Art. 62(3) BGG, failure to pay the cost advance within the additional deadline leads to non-entry; the court therefore did not examine the merits under Art. 108(1)(a) BGG.
