Key legal question
Whether the cantonal court arbitrarily denied loss of earnings damage
Extracted holding
No arbitrariness: it was not untenable to assume she would have continued her previous 50% work in her husband's business, and she failed to provide a concrete basis for calculating lost earnings.
Extracted reasoning
The court held that the claimant bore the burden to allege and substantiate the economic value of her pre-accident work. Without such basis, no concrete calculation under Art. 42(2) OR was possible.
