Key legal question
Whether the internal regional medical service report was sufficient to assess work capacity and invalidity.
Extracted holding
The internal report could not support the assessment because the file lacked a reliable specialist evaluation and the record did not justify the assumed 80% work capacity.
Extracted reasoning
Reports under Art. 49(3) IVV are not expert opinions, but when the authority relies mainly on internal medical material, strict evidentiary scrutiny applies. Here no specialist had assessed work capacity in a reasoned, examination-based way, and the record did not support the internal conclusion.
