Questão jurídica principal
Whether the appeal was sufficiently reasoned to challenge the grace-period order for payment of the cost advance.
Decisão extraída
The appeal did not meet the Federal Supreme Court's reasoning requirements because it attacked the underlying liability dispute instead of explaining how the grace-period order violated federal law.
Fundamentação extraída
Under Art. 42 and Art. 106(2) BGG, grievances must be clearly reasoned; appellatory criticism is insufficient. The amount and basis of the cost advance were already final, and only the grace-period order was under review.
