Kernrechtsfrage
Whether the insured showed a compensable deterioration justifying a disability pension from January 2010.
Extrahierter Entscheid
The medical evidence supported a psychiatric deterioration and total incapacity for work from early 2009, so the pension entitlement from 1 January 2010 remained justified.
Extrahierte Begründung
The Federal Court deferred to the cantonal assessment because the appellant did not show it was unsustainable. The expert report and treating doctors consistently described a patent depressive disorder of sufficient severity, distinct from mere reactive accompaniment to pain.
