Kernrechtsfrage
Whether the complaint against the cantonal decision was admissible as an interlocutory civil matter with irreparable harm
Extrahierter Entscheid
The appeal was admissible because an alleged defective service to Z. could no longer be cured in the final judgment and might affect enforceability abroad.
Extrahierte Begründung
A later remedy would not repair the alleged defect; potential enforcement problems in the USA sufficed to establish irreparable harm.
