Questione giuridica chiave
Whether the dispute could be extended to a full invalidity pension from 1990 to 2006 despite final prior decisions.
Decisione estratta
No; matters already finally decided cannot be brought back into the dispute except through reconsideration or revision.
Motivazione estratta
The earlier pension decisions had entered into force and were not shown to be manifestly incorrect; the administration cannot be compelled to reconsider them absent a justiciable entitlement.
