Questão jurídica principal
Whether the exchanged and amended work declaration created a contract between contractor and bank.
Decisão extraída
No contract was proven; the cantonal findings established that the parties never reached a mutual agreement.
Fundamentação extraída
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.
