Kernrechtsfrage
Whether the constitutional complaint against the cantonal non-entry decision was admissible under Art. 87 OG despite being directed against a separate interim evidence order.
Extrahierter Entscheid
The underlying evidence order was an other interlocutory decision; because no irreparable legal harm was shown, the constitutional complaint was inadmissible.
Extrahierte Begründung
A mere factual disadvantage, such as prolonging or increasing the cost of proceedings, is insufficient. Any alleged prejudice could still be raised and cured in an appeal against the final cantonal judgment.
