Questão jurídica principal
Whether a revision-relevant change in circumstances justified altering the insured person's disability status and pension degree.
Decisão extraída
A revision-relevant change existed: from November 2003 the insured person would have worked 80% in good health instead of 50%, so the mixed method remained applicable but with a higher erwerbsbezogener weight.
Fundamentação extraída
Earlier and later statements, the changed family situation, and the absence of any real employment efforts made an 80% hypothetical workload more probable than 100%.
