Kernrechtsfrage
Whether the remand order caused irreparable legal harm under Art. 93(1)(a) LTF
Extrahierter Entscheid
No irreparable legal harm was shown; a remand and the ordered expertise did not create a legal prejudice that could not be remedied by an appeal against the final judgment.
Extrahierte Begründung
A merely factual disadvantage such as delay or added costs is insufficient; remand orders are generally not immediately appealable on this ground.
