Questão jurídica principal
Whether the pension revision under the invalidity insurance was justified by a relevant improvement in invalid income.
Decisão extraída
Yes. The increase in the insured person's actual invalid income went well beyond ordinary wage growth and justified revision.
Fundamentação extraída
The wage increases in 2006 and 2007 were substantial and exceeded statistical nominal wage development. The lower court correctly applied the parallelism principle and deducted a part of the improvement under Art. 31 IVG.
