Press Release  AG Campbell Sues Trump Administration Over Unlawful Rule That Undermines Affordable Care Act Protections

Boston — Massachusetts Attorney General Andrea Joy Campbell today joined a coalition of 21 attorneys general 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 would make health insurance more expensive, reduce access to coverage, and undermine key protections under the Affordable Care Act (ACA). 

The lawsuit seeks to block provisions of the U.S. Department of Health and Human Services’ (HHS) and Centers for Medicare & Medicaid Services’ (CMS) 2027 Notice of Benefit and Payment Parameters, a federal rule that establishes standards for health plans offered in 2027 and was opposed by the coalition in a March 2026 comment letter.  

“Massachusetts residents are already struggling with the rising cost of healthcare, and attorneys general across the country are working every day to protect consumers and expand access to affordable coverage,” said AG Campbell. “Instead of lowering costs or making it easier for people to get the care they need, the Trump Administration is yet again creating barriers to coverage and shifting even greater financial burdens onto working families. We’re asking the court to stop these unlawful changes and protect the affordable healthcare that millions of Americans rely on.”  

Among other harmful changes, the rule expands eligibility for catastrophic health insurance plans that are ineligible for premium tax credits, offer only limited coverage, and can leave consumers facing significantly higher out-of-pocket costs than standard ACA plans. The rule also allows catastrophic and bronze plans to exceed ACA limits on maximum annual out-of-pocket costs, increasing the financial burden on consumers, and attempts to reinstate several provisions that a federal court recently found to be unlawful.  

The coalition argues these and other provisions unlawfully undermine the ACA’s goal of expanding access to affordable healthcare by increasing costs, reducing enrollment, and shifting financial burdens onto consumers, states, and healthcare providers.  

Congress enacted the ACA to expand access to affordable health insurance, and more than 23 million Americans currently receive coverage through its marketplaces. Today’s lawsuit follows the coalition’s challenge to the Trump Administration’s similar 2025 ACA Marketplace rule. Earlier this week, the U.S. District Court for the District of Massachusetts held a hearing on the parties’ cross-motions for summary judgment in that case, with a final decision expected at a later date.  

In related litigation, a federal court last month vacated several provisions of the Administration’s 2025 rule — including provisions at issue in this case — after finding that they violated the Administrative Procedure Act. The Administration’s new rule setting standards for 2027 health plans, which is the subject of this lawsuit, brings back many of the same provisions and adds new changes that further undermine the ACA. HHS estimates the new rule will cause two million people to lose coverage in 2027 alone and a total of five million by 2030. 

In today’s lawsuit, the coalition argues that the new rule: 

• Reimposes provisions that a federal court has already vacated — including additional income verification requirements and penalties for consumers who do not complete tax-credit paperwork — without addressing the court’s legal concerns. 
• Unlawfully expands eligibility for catastrophic health plans beyond the limits established by Congress in the ACA. 
• Unlawfully allows catastrophic and bronze plans to exceed ACA limits on maximum annual out-of-pocket costs. 
• Will increase costs, reduce enrollment, and shift financial burdens onto consumers, healthcare providers, and states. 
• Was adopted without adequate explanation or a meaningful response to the coalition’s comments, making it arbitrary and capricious under the Administrative Procedure Act. 

Joining AG Campbell in filing today’s lawsuit are the attorneys general of Arizona, California, Colorado, Connecticut, Delaware, Illinois, Maine, Maryland, Michigan, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, Rhode Island, Vermont, Virginia, Washington, and Wisconsin, as well as Pennsylvania Governor Josh Shapiro.
