Key legal question
Whether a hypothetical income should be imputed to the partially disabled claimant in the supplementary benefits calculation, and in what amount.
Extracted holding
In principle, the statutory income formula of Art. 14a OPC-AVS/AI applies unless the insured proves that a higher income can realistically be earned; the cantonal findings were insufficient to depart from that presumption.
Extracted reasoning
The cantonal court relied on a theoretical 70% earning capacity and a former wage, but did not adequately consider the claimant's age, the relevant labour market, and the concrete possibility of obtaining such work. The record did not justify imputing an income above the statutory forfait.
