Questão jurídica principal
Whether the appeal had to be entered into despite the failure to pay the court cost advance within the extended deadline.
Decisão extraída
No. The advance payment was not made within the granted grace period, and the appeal had to be left unheard in simplified procedure.
Fundamentação extraída
A grace period under Art. 62(3) BGG is not extendable; only a properly substantiated legal-aid request with supporting evidence can exceptionally preserve the deadline. The appellant filed such a request only on the last day of the grace period and without proof of indigence.
