Key legal question
When did the statutory waiting period begin for the invalidity pension?
Extracted holding
The waiting period began in spring 2002, not only at the MEDAS examination in May 2005.
Extracted reasoning
The medical record showed a later deterioration with at least 50% work incapacity in spring 2002; the lower court's finding that the start date was unprovable was contradicted by the consistent medical evidence and was therefore manifestly incorrect.
