Questão jurídica principal
Whether the invalidity insurance must finance the wheelchair seat lift and standing function under item 13.02* HVI.
Decisão extraída
The case turns on whether the insured meets the gainful-activity requirement for starred aid devices; the matter must be remitted for further wage and market-value findings.
Fundamentação extraída
Under the settled case law, a legally relevant gainful activity exists only if the insured achieves income of at least the minimum contribution for non-employed persons. The lower court applied an overly broad definition. However, the actual market value of the work, including any in-kind component, had not been sufficiently established.
