Key legal question
Whether a hypothetical income may be imputed to the spouse when calculating supplementary benefits.
Extracted holding
A hypothetical income could not be upheld on the present file because the medical evidence did not sufficiently establish work capacity or capacity loss.
Extracted reasoning
Under supplementary-benefits rules, a spouse's unused earning capacity may be counted only if, in light of family-law duties and the concrete circumstances, gainful work can reasonably be expected. The medical reports produced were too vague, lacked diagnosis and prognosis, and did not prove incapacity to the required degree of probability.
