Kernrechtsfrage
Whether the insured person proved a relevant incapacity for work during coverage with BVG-Sammelstiftung Swiss Life.
Extrahierter Entscheid
No. The onset of the disability-causing incapacity during the coverage period with that fund was not established with sufficient probability.
Extrahierte Begründung
The medical records did not reliably show a significant reduction in work capacity while insured with Swiss Life; later reports and retrospective assessments did not overcome the lack of contemporaneous proof.
