Question juridique clé
Whether the federal appeal against the cantonal decision was admissible.
Solution extraite
No, because the challenged ruling concerned only cantonal rules on subject-matter jurisdiction and did not raise a federal jurisdiction provision.
Motifs extraits
Under Art. 43(1) OG, an appeal may challenge only violations of federal law. The question whether the claim belonged before the lease court or the labor court was governed by cantonal court-organizational law, even if it used federal-law concepts.
