The complaint argues HHS and CMS ignored Democratic attorneys general objections filed in March 2026 and proceeded to finalize provisions designed to undermine the Affordable Care Act. HHS's own estimates project the rule could cause 2 million people to lose coverage in 2027, rising to 5 million by 2030. The specific mechanics of how the rule will be implemented and enforced remain to be detailed in regulatory guidance.
The timing matters. The rule is now finalized for the 2027 plan year, creating urgency before insurers and state marketplaces begin implementation. More significantly, the lawsuit tests whether HHS can reintroduce provisions already struck down by federal courts through new rulemaking—a question that will likely determine the scope of executive authority over ACA marketplace design going forward. Attorneys advising insurers, state exchanges, or consumer advocates should monitor discovery and any preliminary injunction motions closely.
