Questão jurídica principal
Whether the cantonal court arbitrarily found the defendant to be C.'s contractual partner and accepted C.'s version of the agreement
Decisão extraída
The cantonal court had in fact found that the defendant was C.'s contractual partner; leaving open whether the wife was also involved was immaterial.
Fundamentação extraída
The Supreme Court held that the lower court gave coherent, non-arbitrary reasons for crediting C.'s account and rejecting the defendant's version.
