Question juridique clé
Whether the insured was entitled to a higher invalidity pension for the period before 1 September 2007
Solution extraite
The pension assessment based on a 50% residual work capacity led to a 44% invalidity rate; the quarter pension remained in force and the later half pension could not be worsened on appeal.
Motifs extraits
The cantonal court wrongly limited the dispute to one period and relied on average sick-leave certificates instead of residual earning capacity in a reasonable adapted activity. After correcting the record, the Federal Court found a 50% work capacity in all activities and a 44% invalidity degree.
