Kernrechtsfrage
Whether the cantonal court violated federal law by finding that the compensation claim was not sufficiently proven.
Extrahierter Entscheid
No. After reasonable evidentiary efforts, the records remained unavailable; the compensation office had to bear the consequences of proof failure.
Extrahierte Begründung
In social insurance proceedings the court decides on the basis of the most probable facts. Where the investigating authority has taken all reasonable steps and the party bearing the burden cannot produce supporting documents, the court may deny further evidentiary measures and apply the rule that proof failure is borne by the party asserting the claim.
