Key legal question
Whether the claimant was entitled to an invalidity pension from occupational pension insurance despite prior illness before affiliation.
Extracted holding
No entitlement, because the later employment period did not durably interrupt the temporal connection between the earlier incapacity to work and the disability.
Extracted reasoning
The claimant suffered from an intermittent psychotic illness since 2003. Although he worked full-time from January to April 2007, the medical reports showed ongoing treatment, a fluctuating course, and a rapid relapse after resuming work. The improvement was not sufficiently stable and durable to break the temporal link.
