Question juridique clé
Whether the reduction of the invalidity pension was justified under Art. 17 ATSG due to a relevant change in health or earning capacity.
Solution extraite
The record did not establish with sufficient probability a relevant improvement in health or working capacity; the psychiatric report was contradictory and unsuitable as sole basis.
Motifs extraits
The Court found the expert opinion internally inconsistent and based on incorrect factual assumptions. The cantonal court therefore could not rely on it to find a proven revision ground.
