Questione giuridica chiave
Whether the federal civil appeal was admissible against the cantonal decision on local jurisdiction
Decisione estratta
The appeal was not admissible because the challenged ruling concerned a prorogation clause and local jurisdiction based on cantonal procedural law, not a federal civil-law dispute reviewable by appeal.
Motivazione estratta
Constitutional venue arguments had to be raised by constitutional complaint; the validity of a forum agreement concluded before 1 January 2001 was governed by prior law, and the resulting forum was likewise based on that earlier law. Violations of cantonal procedural law cannot be reviewed on appeal.
