Kernrechtsfrage
Whether Art. 21(4) ATSG allowed immediate withdrawal of the pension for refusal of psychiatric treatment.
Extrahierter Entscheid
No. A treatment refusal under Art. 21(4) ATSG requires a reasonable expectation that the treatment will substantially improve earning capacity or create a new earning opportunity; that was not shown here because the disability remained purely somatic.
Extrahierte Begründung
The medical evidence attributed the reduced work capacity solely to physical impairments. Psychiatric treatment might have helped mobilize residual capacity, but it would not have led to a material improvement in earning capacity within the meaning of Art. 21(4) ATSG.
