Key legal question
Whether the conditions for revising the invalidity pension were met due to a worsening health condition.
Extracted holding
No revisable deterioration of the insured person's health was shown; the prior 50% capacity and half pension remained unchanged.
Extracted reasoning
The Federal Court accepted the expert report that the psychiatric condition had not worsened in a legally relevant way. The newly diagnosed somatoform pain disorder did not justify a higher incapacity, and the cantonal findings were not manifestly incorrect.
