Kernrechtsfrage
Whether the damage claim was sufficiently substantiated to be reviewable
Extrahierter Entscheid
The claim was sufficiently documented; the appellant had to concretize his objections based on the numbered file and the contribution overview.
Extrahierte Begründung
The insurer fulfilled its duty to explain the calculation by referring to the contribution overview and other filed documents; the court was not required to search the files on its own.
