Questão jurídica principal
Whether the administrative law appeal should be entered into despite non-payment of the full cost advance within the extended deadline.
Decisão extraída
The appeal cannot be entertained because the second instalment of the ordered advance was not paid within the prescribed time.
Fundamentação extraída
Under Art. 150 OG, the party must secure the likely court costs. If the deadline expires fruitlessly, the court does not enter into the proceeding; the appellant had been expressly warned that late or missing payment would lead to non-entry.
