Key legal question
Whether the cantonal court could reject the psychiatric expertise and deny the pension revision despite the fibromyalgia jurisprudence
Extracted holding
The cantonal court departed unsustainably from settled fibromyalgia case law and arbitrarily assessed the evidence; the revision prerequisites were met.
Extracted reasoning
The expert report showed a clear improvement since 2000. The cantonal court relied mainly on subjective statements from the insured and relatives and did not convincingly challenge the administrative expertise. The required severe psychiatric comorbidity was not established.
