Key legal question
Whether the medical evidence was sufficient to assess work capacity and the right to an invalidity pension from 1 January 2005.
Extracted holding
The file did not permit a reliable and complete assessment of the claimant's health situation and work capacity in the relevant period; further medical and vocational investigations were required.
Extracted reasoning
The MEDAS report expressly left the final assessment of permanent occupational limitations open and was based on a favorable prognosis that later did not materialize. Later treating physicians described a failed return-to-work attempt and ongoing pain and psychological deterioration. The lower court therefore could not rely exclusively on the older expert report and had to clarify suitable alternative work capacity as well.
