Key legal question
Whether the insured's medical and work capacity was sufficiently established for deciding entitlement to vocational measures and an invalidity pension
Extracted holding
The factual findings on work capacity were insufficient for the relevant period; a medical expert assessment was required.
Extracted reasoning
The relied-on medical reports did not provide a legally sufficient basis for the whole period. The later report of Dr. E. indicated limitations, pain, sleep problems, psychosomatic effects, reduced endurance, and concentration issues that could also affect advisory work; the other reports were either too old or not decisive on work capacity.
