Our Take
A courtroom win for ACA defenders that solves half the problem; the other half is now written into law and beyond judicial reach.
Why it matters
Healthcare organizations and insurers face immediate uncertainty about which enrollment restrictions stand and which don't. The ruling clarifies what courts can overturn but exposes the limits of judicial review when Congress acts first.
Do this week
Compliance teams: audit which rule provisions your systems enforce today, separate court-vacated items from those codified in the Big Beautiful Bill, and prepare two operational timelines before end of week.
Judge vacates most of the rule, but the fight is far from over
A federal judge on Friday vacated most provisions of a 2025 Centers for Medicare and Medicaid Services rule that tightened enrollment and eligibility requirements under the Affordable Care Act. The decision marks a legal victory for insurance advocates who challenged the rule as overly restrictive. However, the ruling's practical impact is constrained by a critical fact: many of the rule's core provisions were already written into the GOP's "Big Beautiful Bill," which has become law and sits outside the court's jurisdiction.
The exact provisions vacated by the judge remain unclear from public reporting, but the pattern is now visible. Courts can strike down agency rules. Congress can codify the same policies into statute, where judicial review becomes far more difficult and requires a different legal argument.
The real issue is legislative, not regulatory
This decision illustrates a structural shift in how healthcare policy is now made. Historically, CMS rules could be challenged and sometimes overturned. Today, controversial enrollment and eligibility changes are being embedded directly into statute by Congress, making them far harder to reverse through litigation alone.
For insurers and healthcare organizations, the ruling creates immediate operational ambiguity. Provisions vacated by the court must be unwound; provisions codified in the Big Beautiful Bill remain binding. The divergence means compliance cannot follow a single timeline or unified interpretation. Insurance advocates won a battle in federal court, but the war is being fought in Congress, where they are currently losing.
Separate what's dead from what's still alive
Any healthcare organization or plan that implemented the CMS rule needs to know which specific provisions the court struck down and which remain enforceable under statute. This is not a binary "roll back everything" moment. The court's decision applies only to the regulatory provisions it vacated. Provisions already in law persist and must continue to be enforced until Congress acts, which is not guaranteed.
Audit your enrollment and eligibility systems now. Identify which rules came from the CMS regulation (now vacated) and which came from the Big Beautiful Bill (still in force). Update your systems accordingly, but recognize that the statutory provisions are not your organization's problem to solve legally. That burden falls on Congress or future litigation that directly challenges the statute itself.
