Questão jurídica principal
Whether the mixed-method assessment and the earning-capacity assessment for the lucrative part were unlawful, requiring a return from ATF 125 V 146.
Decisão extraída
The established case law on part-time insured persons under the mixed method remains applicable; no reason was shown to depart from it.
Fundamentação extraída
The cited doctrine brought no genuinely new element. The court reiterated that, for the lucrative part, invalidity is assessed by comparing the last attainable income in the actual part-time activity with the income reasonably achievable in a suitable job, not with full hypothetical earning capacity.
