Key legal question
Whether the Swiss courts had international jurisdiction over the non-information estate claims against X.
Extracted holding
The cantonal court wrongly treated the Federal Supreme Court's prior remand as having finally decided jurisdiction for claims beyond information requests; jurisdiction over those other claims still had to be examined.
Extracted reasoning
The earlier federal judgment concerned only information claims linked to an estate dispute. The remand to proceed with the action could not be read as a final ruling on all other claims.
