Questão jurídica principal
Whether the nullity appeal was admissible despite non-payment of the ordered advance on costs.
Decisão extraída
No. Because the appellant did not pay the advance within the extended deadline, the appeal submissions were inadmissible.
Fundamentação extraída
The appellant had obtained a generous extension at his own request, yet provided no concrete information about his financial situation or his asserted efforts to pay. Any implicit request for legal aid would therefore have to be denied; without payment, the submissions are inadmissible under Art. 150 para. 4 OJ.
