Questão jurídica principal
Whether the insured was entitled to a three-quarter IV pension from 1 January 2004.
Decisão extraída
The lower court had to be set aside and the matter remitted because the decisive income basis was insufficiently clarified; entitlement could not yet be finally determined.
Fundamentação extraída
The Federal Court held that, although invalidity findings from accident insurance may be relevant, divergence between the employers' income statements had to be resolved first. The cantonal court relied on one employer statement without clarifying the inconsistency, making the factual findings manifestly incorrect.
