Kernrechtsfrage
Whether there was a revision ground justifying removal of the disability pension.
Extrahierter Entscheid
The insured person's mental health had improved compared with the original pension award; therefore a revision ground existed.
Extrahierte Begründung
The 2001/2002 baseline showed complete incapacity from severe depression. The 2017 psychiatric expert report still found a depressive disorder, but only medium severity and 50% incapacity, which demonstrated a material change in health status.
