Questione giuridica chiave
Whether the original disability pension award was manifestly incorrect and could be reopened under reconsideration rules.
Decisione estratta
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.
Motivazione estratta
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.
