Questão jurídica principal
Whether a separate appeal is admissible against a procedural warning of possible reformatio in peius with a right to comment.
Decisão extraída
The complaint was not admissible because the challenged procedural order caused no irreparable harm and would not immediately lead to a final decision if allowed.
Fundamentação extraída
Under Art. 93(1) BGG, such an interlocutory procedural order is not independently appealable; counsel should have known this.
