Kernrechtsfrage
Whether the reform appeal against the incidental decision on international jurisdiction and lis pendens was admissible
Extrahierter Entscheid
The appeal was admissible insofar as it relied on federal rules governing international jurisdiction and on the issue of standing, but only within the limits of reform review.
Extrahierte Begründung
International conventions count as federal law; jurisdiction within Art. 49 OG includes lis pendens issues. Standing could be reviewed under Art. 50 OG because a successful objection could finally dispose of the counterclaim.
