Kernrechtsfrage
Whether the original disability pension award was manifestly incorrect and could be reopened under reconsideration rules.
Extrahierter Entscheid
The original pension decision was not shown to be manifestly incorrect; the status assessment was at least defensible on the record available at the time.
Extrahierte Begründung
The earlier file contained medical reports and indications that the insured had declined a full-time workload because of back problems. Assessing the hypothetical work status involved appreciable discretion, so reconsideration is only possible if the original assessment was untenable, not merely arguable.
