Kernrechtsfrage
Whether the insured person's changed health condition justified a new right to a half disability pension from November 2005
Extrahierter Entscheid
The courts accepted a relevant change in circumstances: work capacity fell from 100% to 50% due to a recurrent depressive disorder and generalized anxiety.
Extrahierte Begründung
The Federal Tribunal deferred to the cantonal court's complete review of the medical evidence and found no manifestly incorrect fact-finding. The expert report of psychiatrist Z. was persuasive, while the contrary opinions did not outweigh it.
