Question juridique clé
Whether the opposition against the 4 August 2004 decision was admissible despite targeting matters already decided on 23 April 2003.
Solution extraite
The 23 April 2003 decision had entered into force; only the pension calculation was later replaced. The opposition was therefore late to the extent it attacked settled aspects of the earlier decision.
Motifs extraits
The 2004 decision modified only the calculation basis of the same disability pension, not the existence or duration of the entitlement. Those other elements were covered by res judicata once the 2003 decision became final.
