Key legal question
Whether the insurer could obtain definitive debt-enforcement opening for unpaid compulsory health insurance premiums, interest and dunning fees.
Extracted holding
Yes. The insurer had a valid enforcement title and the insured person raised no substantive objections to the claimed premiums, interest, or fees.
Extracted reasoning
For unpaid premiums after dunning, the insurer may initiate enforcement and issue a formal decision that expressly lifts the objection; that decision constitutes a definitive opening title. The dunning fees were permissible under the insurer's regulations and were considered overall reasonable.
