Questione giuridica chiave
Whether the cantonal decision was a 'main judgment' appealable to the Federal Court under Art. 58(1) OG.
Decisione estratta
A decision that only establishes liability in principle and sends the parties to a civil judge for quantification is not a main judgment.
Motivazione estratta
Under Art. 58 OG, only judgments that finally determine the claim and definitively end the cantonal proceedings are appealable. The challenged decision did not finally dispose of the compensation claim because the amount still had to be fixed separately.
