Question juridique clé
Whether the claimant had a pension-relevant degree of invalidity in adapted work between December 2004 and July 2007.
Solution extraite
The medical record did not allow a reliable assessment of work capacity in adapted employment for the relevant period; further clarification was required.
Motifs extraits
The lower court relied on incomplete and partly incorrect medical assessment. The treating and consulting physicians addressed mainly the former job, while the expert report did not clearly answer adapted-work capacity for the contested period. The duty to investigate was therefore violated.
