Kernrechtsfrage
Whether the Z.________ expert report was sufficiently probative for a decision on disability pension entitlement in the presence of a somatoform pain disorder.
Extrahierter Entscheid
The report was not sufficiently convincing because it dealt only summarily with the relevant jurisprudential criteria and relied largely on the claimant's own complaints; a further medical assessment was required.
Extrahierte Begründung
In cases of pain syndromes without clear organic findings, experts must address the decisive criteria for overcoming the disorder and assess the claimant's psychic resources. The report did not provide a thorough discussion, did not refer to psychiatric testing, and lacked the evidentiary force needed for a factual finding on work capacity.
