Guidance
Some insurers may be non-compliant with the above statutes and are imposing unlawful
overcharges and penalties on insured individuals as a result of open-container and marijuana
possession violations. As such, CSI is advising insurers to immediately review and update their
rates, rules, and underwriting as they pertain to §§ 61-8-1026 and 61-8-1027, M.C.A.
Insurance rates that are not compliant with §§ 61-8-1026 and 61-8-1027, M.C.A., are
unlawful. Portions of premiums associated with non-compliant rates are considered overcharges.
§ 33-18-212, M.C.A. To rectify the improperly imposed overcharges, the insurer must issue a
refund of such monies to affected parties with interest. § 27-1-202, M.C.A.
If an insurer discovers that it has been unlawfully penalizing an insured individual for a
violation of §§ 61-8-1026(1) or 61-8-1027(1), M.C.A., the insurer must immediately cease doing
so. Insurers must then submit updated rates and rules to CSI and issue a refund of the
overcharged premium amounts, with interest, to the affected individual if it has not already done
so. §§ 33-16-203, 27-1-211, M.C.A.

Affected parties have a right to interest accrued on such overcharges. § 27-1-211, M.C.A.
When harm to affected parties is certain, the interest rate must be equal to the rate for bank prime
loans published by the federal reserve system, plus 3%. §§ 27-1-211, 25-9-205, M.C.A. Additional
information on interest rates pertaining to premium refunds may be found in CSI’s Advisory
Memorandum Regarding Interest Rate on Premium Refunds in Consent Agreements.
Additionally, insurers must submit a certification to CSI that details legal compliance and
any required premium refunds issued. § 33-2-705, M.C.A. Insurers that are not required to file
rates pursuant to § 33-16-103 must still correct their rates and underwriting internally.
All insurers that use the noted open-container or marijuana possession violations to
determine rates, premiums, underwriting, or terminate coverage must submit the certification
attached to this advisory memorandum in a rate filing through NAIC SERFF by October 1, 2025.
§ 33-2-705, M.C.A. This certification requirement applies even if an insurer has already updated
their rates and rules as they pertain to §§ 61-8-1026 and 61-8-1027, M.C.A.
In sum, if an insurer discovers unlawful penalization of an insured individual for violating
§§ 61-8-1026(1) or 61-8-1027(1), M.C.A., it must:
1. Immediately cease the unlawful practice;
2. Submit updated rates and rules to CSI, unless exempt under 33-16-103, M.C.A.;
and
3. Issue a refund of overcharged premium amounts with interest to affected
individuals, pursuant to §§ 33-16-203 and 27-1-211, M.C.A.
4. Fill out the attached certification form and submit it to CSI through SERFF by
October 1, 2025.
It is of the utmost importance that insurers comply with Montana law. Insurers have a
duty to rectify their errors and failure to do so may result in action by CSI.
Questions concerning rate and rule filings should be directed to CSI’s Chief Actuary and
Rate Bureau Chief, Mari Kindberg, at mkindberg@mt.gov.
This advisory memorandum does not enlarge, delimit, or otherwise modify any
requirements of applicable law or in any way limit the authority of CSI under
applicable law. CSI encourages interested persons to consult with independent legal
counsel for guidance on the application of law to any particular circumstances.
This guidance is necessitated by policies enacted by the Montana Legislature. CSI is
required to enforce this legislative requirement and for present purposes does not
opine on such legislative judgments.
