Kernrechtsfrage
Whether the required temporal and material nexus existed between the work incapacity during the pension relationship and the later disability.
Extrahierter Entscheid
No pension fund liability existed because the earlier incapacity was interrupted by a sufficiently long recovery period and the IV-based disability timeline was not shown to be obviously wrong.
Extrahierte Begründung
Under Art. 23 BVG, benefits are owed only if the incapacity causing disability arose while insured and there is a close temporal and causal link. The court relied on the binding effect of the IV decisions, found no obvious factual error, and held that the post-1993 insurance link had ended.
