Questione giuridica chiave
Whether the exchanged and amended work declaration created a contract between contractor and bank.
Decisione estratta
No contract was proven; the cantonal findings established that the parties never reached a mutual agreement.
Motivazione estratta
Contract formation requires concordant mutual declarations of intent. The cantonal court found, on binding factual findings, that the parties had no direct contact and no actual consensus; therefore no interpretation under the reliance principle was possible.
