Question juridique clé
Whether the Federal Supreme Court could hear the appeal against the cantonal interlocutory decision on jurisdiction.
Solution extraite
The appeal was admissible because the challenged ruling concerned jurisdiction and was separately appealable; the value threshold and exhaustion of cantonal remedies were satisfied.
Motifs extraits
Jurisdictional interlocutory decisions are appealable under Art. 92 BGG. The matter was financially significant, and no cantonal remedy remained open for the federal-law jurisdictional complaint.
