Kernrechtsfrage
Whether the start of the insured person's incapacity for work in October 2002 was sufficiently proven
Extrahierter Entscheid
The medical file was too inconsistent and incomplete to establish the onset of incapacity for work with the required probability; independent psychiatric reassessment was necessary.
Extrahierte Begründung
The treating doctors confirmed full incapacity only from June 2004, while earlier limitations were not quantified. The RAD reports were not sufficiently substantiated and did not adequately address the only contemporaneous psychiatrist's assessment. The evidentiary basis was therefore not conclusive enough for a merits decision.
