Kernrechtsfrage
Whether the BVK must pay an invalidity pension based on work incapacity arising during the coverage period.
Extrahierter Entscheid
The insured person did not prove an interruption of the temporal connection between the relevant work incapacity and the later invalidity; BVK therefore owes no invalidity pension.
Extrahierte Begründung
Although some medical reports suggested full work capacity in adapted work, the overall evidence showed an uncertain prognosis, persistent pain, and no period of at least three months with effective, sustainable capacity sufficient to earn a pension-precluding income.
