Rate hearings, intervenors and public input

When states hold hearings

Rating laws use a few kinds of triggers. They vary by state, line and rating system, so read the governing statute for each filing.

On the regulator's own motion

Many rating laws let the commissioner call a hearing on a filing. In North Carolina, for filings by the North Carolina Rate Bureau, G.S. 58-36-20 lets the Commissioner, within 50 days after a filing, give written notice of how the filing fails to comply and set a hearing at least 30 days later. If no notice of hearing issues within 50 days, the filing is deemed approved. At the hearing the Bureau carries the burden of proving the proposed rates are not excessive, inadequate or unfairly discriminatory, and the Commissioner's order must include findings of fact and be issued within 45 days after the hearing ends, or the filing is deemed approved.

On request, and above thresholds

Under California's Proposition 103, Insurance Code § 1861.05(c) requires the commissioner to notify the public of every rate application. The application is deemed approved 60 days after public notice unless one of three things happens:

1. a consumer or consumer representative requests a hearing within 45 days of public notice and the commissioner grants it, or declines it with written findings;
2. the commissioner decides on their own motion to hold a hearing; or
3. the proposed change exceeds 7% of the current rate for personal lines or 15% for commercial lines, in which case the commissioner must hold a hearing on a timely request.

The same subdivision deems an application approved 180 days after the department receives it, unless it has been disapproved by final order after a hearing or extraordinary circumstances exist; § 1861.05(d) defines those circumstances, including hearings commenced within the 180 days.

At the filer's request

Rating laws commonly give an insurer or rating organization a right to a hearing on an adverse order made without one. The NAIC's model rate and policy form law guideline, for example, lets an aggrieved insurer or advisory organization request a hearing within 30 days after notice of an order. The same model gives an insured aggrieved by how a rating system was applied a path to appeal to the commissioner.

Public notice and comment

Public input starts with notice. California's § 1861.06 requires public notice under Proposition 103 to be distributed to the news media and to anyone who asks to be on the mailing list. The Department of Insurance describes its practice as issuing public notices of rate filings every Friday, with intake required to notify the public within ten days of receiving a filing.

Other states build in a comment period. North Carolina's G.S. 58-36-15 opens Rate Bureau filings to public inspection immediately on submission and requires the Department to receive public comments on a property insurance rate filing at least 30 days before a notice of hearing issues. Comments can be submitted by email, by mail or in person, and are shared with the Bureau.

Public comment periods let consumers, local officials and others put concerns on the record. Formal intervention, where the state allows it, goes further.

Intervenors and California's Proposition 103

California's intervenor system is a well-documented example of formal outside participation in rate review. Insurance Code § 1861.10(a) lets any person initiate or intervene in any proceeding under the chapter, challenge the commissioner's actions under the article and enforce its provisions. Section 1861.10(b) requires the commissioner or a court to award reasonable advocacy and witness fees and expenses to a person who represents the interests of consumers and has made a substantial contribution to an order, regulation or decision. Where the advocacy responds to a rate application, the applicant pays the award.

The Department's intervenor program pages, including how to participate, describe three steps, governed by regulations beginning at Title 10, California Code of Regulations § 2661.1:

1. Eligibility. A group applies to the Public Advisor for a finding of eligibility to seek compensation. The Department says groups representing the insurance industry are not eligible.
2. Intervention. The group files a petition to intervene and a petition for a hearing on the specific rate application.
3. Compensation. At the end of the proceeding, the intervenor requests an award, which depends on showing a substantial contribution.

The Department publishes petitions to intervene, eligibility petitions and past awards. In August 2026 it announced a new regulation, effective August 11, 2026, that among other things clarifies when administrative law judges take jurisdiction over a rate application, limits intervenors to issues raised in their petition unless they show good cause, defines when fees are reasonable, and adds disclosure requirements for non-profit intervenors.

For a filer, intervention means another party reviewing the application in detail, asking questions, possibly hiring its own actuaries and arguing for a different rate, with its reasonable costs charged to the filer if it qualifies for an award.

What a hearing involves

A rate hearing is an adjudicative proceeding, not a meeting. In California, § 1861.08 provides that Proposition 103 hearings follow the state's Administrative Procedure Act, are conducted by administrative law judges and allow discovery that is liberally construed. Section 1861.05(b) puts the burden of proving that the requested change is justified on the applicant. Section 1861.055 requires the judge to issue a decision within 30 days of the close of the record.

In practical terms, a filer in a hearing should expect:

• A formal record. The filing, exhibits, testimony and correspondence become evidence, and the decision rests on that record.
• Discovery. Requests for data and documents behind the filing, sometimes well beyond what the original exhibits showed.
• Witnesses. Actuarial and other experts who testify to the indication and selections and are cross-examined.
• Time. Statutes set outer limits, but a hearing adds substantial work and can delay the effective date.
• Cost. Counsel, expert witnesses and, where the law provides for it, intervenor awards.

How to prepare

• Know the triggers for each state. Check early whether the requested change, the line or the rating law could lead to a hearing, so the possibility is part of the plan rather than a surprise.
• Build the filing as if it will be cross-examined. Every selection should have support that a skeptical actuary can follow. Gaps in the actuarial memorandum become discovery requests.
• Keep the record consistent. Figures that do not tie between the memorandum, exhibits and rate pages are easy targets.
• Watch public notices and petitions. In states with public notice, track when the comment or hearing request window opens and closes for your filing.
• Prepare witnesses early. Identify who will testify on trend, catastrophe loads, expenses and the selected change, and make sure they can explain the workpapers behind each one.
• Plan the calendar and budget. Include the possibility of a hearing in the target effective date and in the cost of the filing. Planning a rate change covers the wider timeline.
• Learn from prior proceedings. Public filings, hearing decisions and intervenor petitions show which issues have been contested in a state and line.
