Questione giuridica chiave
Whether the federal civil appeal was admissible against a cantonal decision on prud'hommes jurisdiction based on a purported employment contract.
Decisione estratta
The appeal was manifestly inadmissible because the underlying issue was one of pure cantonal law and no properly reasoned constitutional violation was raised.
Motivazione estratta
Cantonal law governing the labor court's material jurisdiction remained cantonal even though it used federal-law concepts. A civil appeal cannot be based on breach of cantonal law as such; review of arbitrary application of cantonal law requires a substantiated constitutional grievance under Art. 106(2) LTF, which was absent.
