Key legal question
Whether the SUVA validly revoked the invalidity pension and helplessness allowance due to a revision-relevant change in health condition.
Extracted holding
Yes. The surveillance and medical evidence established that no psychically caused work-incapacitating impairment persisted, so the entitlement had lapsed.
Extracted reasoning
The court relied on the unobjectionable observation evidence, especially the airport surveillance, together with the psychiatric assessments by Dr. med. K., which convincingly showed that the insured person was no longer suffering from a relevant disorder and had simulated symptoms.
