Questão jurídica principal
Whether the Obergericht was entitled to dismiss the nullity complaint for lack of an appealable procedural decision
Decisão extraída
Yes. The letter of 25 February 2009 was only legal information and did not constitute a procedural ruling.
Fundamentação extraída
The applicant failed to show that the lower court's characterization was wrong; the letter merely informed him about the course of proceedings, expressed a legal view, and invited a response.
