Kernrechtsfrage
Whether the cantonal arbitral tribunal under Art. 57 LAA had subject-matter jurisdiction over the fee dispute between the insurer and the hospital provider.
Extrahierter Entscheid
Yes. The dispute concerned the appropriateness and economic necessity of treatment furnished under accident insurance, which falls within the arbitral tribunal's jurisdiction.
Extrahierte Begründung
Art. 57 LAA covers disputes arising from the legal relationship between accident insurers and medical providers. Where the provider claims fees for treatment whose appropriateness or economy is contested, the matter belongs to the arbitral tribunal even if the insurer had not issued a prior benefits decision.
