Questão jurídica principal
Whether the dispute could be extended to a full invalidity pension from 1990 to 2006 despite final prior decisions.
Decisão extraída
No; matters already finally decided cannot be brought back into the dispute except through reconsideration or revision.
Fundamentação extraída
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.
