Key legal question
Whether the factual and medical situation changed materially enough to justify revising the half disability pension
Extracted holding
No relevant change in the insured person's health or work capacity was shown for the period between the 2001 decision and the 2005 objection decision.
Extracted reasoning
The medical evidence supported a continued 50% work capacity in adapted secretarial work. The court found the cantonal assessment convincing and saw no clinical basis for the alleged new diagnoses or deterioration.
