Questão jurídica principal
Whether the complaint could be entered into after non-payment of the cost advance.
Decisão extraída
No entry was possible because the appellant did not pay the advance by the extended deadline and did not seek legal aid.
Fundamentação extraída
Under Art. 62(3) BGG, failure to pay the cost advance within the set time limit justifies non-entry under Art. 108(1)(a) BGG.
