AG Bonta and AG Davenport co-led a coalition of 21 AGs and the Governor of Pennsylvania in filing a lawsuit in the U.S. District Court for the Northern District of California to challenge a federal rule that once again illegally undermines the Affordable Care Act and would make health insurance more expensive and harder to obtain for millions of Americans. The lawsuit seeks to block provisions of the U.S. Department of Health and Human Services’ and Centers for Medicare & Medicaid Services’ 2027 Notice of Benefit and Payment Parameters, a federal rule that sets standards for health plans offered in 2027 and was opposed by the coalition in a March 2026 comment letter.

“The Affordable Care Act was designed to make healthcare more affordable and accessible. But once again, this Administration is moving in the wrong direction by adopting harmful provisions that push consumers into bare-bones plans and strip away critical protections. We are returning to court to challenge these unlawful changes. At a time when families are already facing rising costs, they cannot afford to pay more for coverage that gives them less.” -AG Bonta
