Questão jurídica principal
Whether the refusal to stay all ongoing proceedings and deadlines was separately appealable to the Federal Supreme Court.
Decisão extraída
The challenged letter was an independently opened interim order; however, it was not appealable because the appellant failed to show a non-reparable legal disadvantage.
Fundamentação extraída
The stay concerned ongoing main proceedings, not the appeal proceedings themselves. Under Art. 93 BGG, a separate appeal requires a non-reparable legal disadvantage; mere factual burdens, delay, or continued litigation pressure are insufficient.
