Key legal question
Whether the pension revision decision was based on sufficient medical evidence, especially regarding psychiatric assessment.
Extracted holding
The medical basis was insufficient because the psychosomatic report did not satisfy the required specialist qualifications for a psychiatric evaluation; further investigations were necessary.
Extracted reasoning
Psychiatric diagnoses were central to the original pension award and to the revision dispute. The psychosomatic part of the assessment was not an actual psychiatric examination, and the persons involved did not clearly have the required psychiatric specialist qualification at the relevant time.
