Decisão extraída
The pension revocation was upheld because the insured person's health had improved significantly and no longer gave rise to invalidity.
Fundamentação extraída
The cantonal court could rely on the psychiatric expert report and its supplement; the complaint did not show any manifest error or need for further evidence. The observation and the medical assessment were considered lawful and sufficient.
