In early August 2026, a coalition of state attorneys general filed lawsuits challenging a 2027 rule issued by the Trump administration that would expand eligibility for catastrophic health‑insurance plans, raise out‑of‑pocket cost limits, and add new income‑verification requirements. The first filing, led by California and New Jersey attorneys general, argued the rule would make coverage harder to obtain and could push millions into higher‑cost plans.

Two days later, additional attorneys general from Washington, Delaware and the governor of Pennsylvania joined the suit, filing in the Northern District of California. They reiterated concerns that the rule would increase costs, reduce enrollment, and shift financial burdens onto consumers, states, and providers, undermining the Affordable Care Act.

Both lawsuits seek to block enforcement of the rule and preserve the affordability and accessibility of ACA marketplace coverage.
