Kernrechtsfrage
Whether the invalidating incapacity for work began while the respondent was insured with the appellant pension fund.
Extrahierter Entscheid
The relevant incapacity for work was not shown to have started during the appellant's insurance period; the later invalidity was not attributable to an incapacity whose onset was proven in real time within that period.
Extrahierte Begründung
The period of reduced work activity lacked contemporaneous medical confirmation of incapacity, the employee resumed work for a substantial period, and no clear, contemporaneous workplace evidence showed a relevant loss of earning capacity before the new employment relationship.
