Kernrechtsfrage
Whether the original grant of the invalidity pension was manifestly erroneous and could be withdrawn by reconsideration under Art. 53(2) LPGA.
Extrahierter Entscheid
The original pension award was not manifestly erroneous; the medical record at the time supported total incapacity and the sociocultural factor was not decisive.
Extrahierte Begründung
Contemporaneous medical reports showed severe post-traumatic stress and persistent somatic pain, with all doctors then attesting total incapacity. The file did not show an obvious mistake in the initial assessment.
