The California Department of Insurance Submits Its Final Proposal on Overhauling the Prop 103 Intervenor Process

In an effort to bring more transparency and accountability to the intervenor process under Proposition 103, the California Department of Insurance (the “Department”) issued its final proposed Intervenor and Administrative Hearing Bureau Fairness and Accountability regulations and submitted them to the Office of Administrative Law (“OAL”) for approval on April 17, 2026. This submission follows months of public engagement by the Department, which included multiple comment periods and significant testimony from consumer advocates, insurance industry and the public.
