Kernrechtsfrage
Whether the appellant was entitled to a three-quarter invalidity pension instead of a quarter pension
Extrahierter Entscheid
The court found no basis to increase the pension; the quarter pension remained justified.
Extrahierte Begründung
The MEDAS expert opinion was probative. The contrary medical reports did not establish additional disabling limitations. The assessed residual capacity in adapted work and the income comparison did not show a higher degree of invalidity.
