Questione giuridica chiave
Whether a direct contract of work existed between the contractor and the buyer for the extra works
Decisione estratta
No reviewable basis showed a directly concluded contract of work, especially as the existence of discussions and agreement on payment was not established.
Motivazione estratta
The appeal challenged the canton court's factual findings and evidence assessment, which are binding on reform appeal; alleged facts about orders, representation, and agreement on price were inadmissible.
