Question juridique clé
Whether the appellant was entitled to a full or three-quarter disability pension instead of a half pension.
Solution extraite
The appeal showed no grounds to disturb the cantonal court's assessment of the medical evidence and residual work capacity; the half pension remained justified.
Motifs extraits
The Court found no objectively incorrect factual findings, no indication that the medical records were incomplete, and no need for further investigations. The weighing of medical reports belongs to fact-finding and is not reviewable under the limited federal review standard.
