Key legal question
Whether the disability pension waiting period began before 2007-05-30.
Extracted holding
The waiting period began on 2007-05-30; earlier incapacity was not proven with the required probability.
Extracted reasoning
Medical reports uniformly confirmed incapacity only from 2007-05-30. The earlier part-time work at the hospital did not show a documented loss of performance, and the employer records did not indicate a relevant reduction in work capacity.
