Key legal question
Whether the federal appeal was admissible against the cantonal court's non-entry decision based on lack of subject-matter jurisdiction of the labor court.
Extracted holding
The appeal was not available because the challenged ruling concerned a cantonal procedural question of subject-matter jurisdiction, not a reviewable issue of federal substantive law.
Extracted reasoning
The decisive question was whether the action could be brought before the labor court, which is governed by cantonal procedural law. Although that jurisdictional question depended on the prior civil-law characterization of the relationship, the federal appeal could not be used to review the cantonal procedural ruling. Any alleged unconstitutional application of cantonal law had to be raised by constitutional complaint.
