Kernrechtsfrage
Whether witnesses had to be heard to establish an agreement on allocating the disputed costs
Extrahierter Entscheid
No. The refusal to hear witnesses did not violate the right to be heard because the agreement would not have been legally decisive.
Extrahierte Begründung
An anticipatory assessment of evidence was permissible since any agreement to shift the costs to the insured would be ineffective under mandatory pension-law rules.
