Question juridique clé
Whether the appeal could challenge the pension award before 1 December 2007.
Solution extraite
The appeal was insufficiently reasoned for the period before 1 December 2007, so the court did not enter into it for that part.
Motifs extraits
The MEDAS assessment concerned only the period from the August 2007 examination onward; the written appeal did not provide legally sufficient reasons extending to the earlier pension periods.
