Key legal question
Whether the revision of the AI pension and its abolition as of 1 January 2006 was lawful.
Extracted holding
The insured person had materially improved, and the psychiatric condition that had justified the pension no longer caused incapacity for work.
Extracted reasoning
The last final merits decision is the temporal starting point for revision. Somatic impairments remained stable and did not limit work capacity; the only relevant change concerned the psychiatric domain, where the prior regressive/hypochondriac state was no longer confirmed and was replaced by a non-disabling somatoform pain syndrome.
