Kernrechtsfrage
Whether the insured was entitled to an ordinary invalidity pension despite the timing of the onset of invalidity.
Extrahierter Entscheid
No ordinary pension was due because invalidity was found to have arisen on 1991-02-01, when the insured lacked the required one-year contribution period.
Extrahierte Begründung
The medical evidence supported a long-standing incapacity dating back to 1988, and the contrary evidence did not show a manifestly incorrect factual finding. The statutory insurance conditions were therefore not met.
