Questão jurídica principal
Whether the insurer could obtain definitive debt-enforcement opening for unpaid compulsory health insurance premiums, interest and dunning fees.
Decisão extraída
Yes. The insurer had a valid enforcement title and the insured person raised no substantive objections to the claimed premiums, interest, or fees.
Fundamentação extraída
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.
