Key legal question
Whether the cantonal court arbitrarily refused to consider witness testimony about attempts to contact the client before selling the bonds.
Extracted holding
No. The cantonal court could reasonably discount the testimony of bank employees and the client's former representative because of their ties and the limited, partly contradictory content of the evidence.
Extracted reasoning
Close professional links, participation in preparing the case, and the witnesses' involvement in the disputed transactions were objective reasons to treat the testimony with caution or disregard it entirely. The applicant also failed to show that the evidence would have been decisive.
