Questão jurídica principal
Whether the Federal Court could hear the public-law appeal despite the case concerning tariff application in an individual case.
Decisão extraída
Yes; this was not a tariff dispute under Art. 53 KVG, but a question whether the specific billing was tariff-compliant and whether a partial reimbursement claim existed.
Fundamentação extraída
The dispute concerned application of an existing tariff to a single case, not the setting of tariffs or prices, so the appeal was admissible.
