Key legal question
Whether the cantonal court assessed the evidence arbitrarily regarding later value-adding works and their proof.
Extracted holding
No arbitrariness was shown in the finding that no post-1978 works were proven by documents or witnesses, nor in the assessment of the insurance-value evidence.
Extracted reasoning
The tenants' references did not establish that the appellate court accepted their version; the insurance witness relied partly on the tenant's own statements, spoke only of unspecified additional investments, and the forced-sale price cast doubt on probative value.
