Questione giuridica chiave
Whether the reform appeal could challenge the cantonal court's factual finding that SIA 118 was not incorporated into the contract.
Decisione estratta
No; the appeal was based on a factual allegation not established below, so it was inadmissible to that extent.
Motivazione estratta
A reform appeal is limited to federal law review and normally binds the Federal Court to the facts found by the cantonal court, absent the narrow statutory exceptions. The appellant relied entirely on an unproven contractual incorporation of SIA 118.
