Kernrechtsfrage
Whether the withdrawal of the half invalidity pension was lawful despite the earlier grant based on psychiatric symptoms.
Extrahierter Entscheid
The pension withdrawal was lawful because the original award was based on an incomplete and legally insufficient assessment, and the later interdisciplinary expert report supported no continuing pension entitlement.
Extrahierte Begründung
The court held that the original 2004 award lacked a proper expert basis and that the psychosocially driven depressive reaction did not establish a self-contained disabling psychiatric disorder. The later hearing defect in the cantonal proceedings could not affect the outcome.
