Questione giuridica chiave
Whether the reform appeal was admissible despite challenging the cantonal court's factual findings on causation.
Decisione estratta
The appeal was inadmissible because it sought to dispute binding factual findings, not a review of a legal issue properly open on reform appeal.
Motivazione estratta
Natural causation is a question of fact, while adequate causation is a question of law. The cantonal court had rejected the claim for lack of natural causation; the appellant therefore attacked the facts under the guise of alleging an error in adequate causation.
