Kernrechtsfrage
Whether the staatsrechtliche Beschwerde was admissible against the cantonal remand judgment.
Extrahierter Entscheid
No admissible constitutional complaint lay because the remand decision was an interlocutory decision and no irreparable legal harm was shown.
Extrahierte Begründung
Under Art. 87 OG, interlocutory decisions are only challengeable by constitutional complaint if they may cause irreparable harm; none was established here, including as to costs.
