Kernrechtsfrage
Whether the appeal was admissible despite the appellant's procedural conduct.
Extrahierter Entscheid
The appeal was inadmissible because the appellant's conduct was abusive and contradictory; it could not challenge on appeal the medical assessment it had itself relied on below.
Extrahierte Begründung
The insurer must clarify the facts before issuing its decision, or at least request remittal in the cantonal response if it considers the medical file insufficient. Having omitted such steps and remained silent below, it acted contra factum proprium and lost protection under the law.
