Supreme Court dismissed cassation; only facts proven in the trial court can serve as the basis for supplementary pension decisions.

The Supreme Court dismissed the appellant's cassation against a lower court's refusal to grant a supplementary work accident pension. The appellant argued that medical opinions from a different social insurance proceeding should establish the causal link between his disability and the work accident, but the court held that only facts proven during the current trial can form the basis for such a claim. Consequently, the court ruled that the lower court correctly relied solely on expert opinions presented in the present proceedings, which found no causal connection between the appellant's current disability and the past work accident.
