Key legal question
Whether the cantonal court arbitrarily assessed the evidence by finding that A. had not clearly consented to the pledge of her shares.
Extracted holding
The appellant failed to show that the cantonal court's assessment of the evidence was manifestly untenable.
Extracted reasoning
The testimony relied on by the appellant came from persons involved in the transaction and was not decisive without corroboration; the remaining circumstances did not compel a finding of informed consent.
