Defending the Affordable Care Act

On February 28, 2018, Texas filed the lawsuit to dismantle the ACA in the United States District Court for the Northern District of Texas, Fort Worth Division, and was joined by 19 other states. On April 9, 2018, the Attorney General's Office and the Attorneys General of Connecticut, Delaware, Hawai'i, Illinois, Kentucky, Massachusetts, Minnesota by and through its Department of Commerce, New Jersey, New York, North Carolina, Oregon, Rhode Island, Vermont, Virginia, Washington, and the District of Columbia, sought to intervene in the federal lawsuit to vigorously defend the ACA and the millions of families across the country who rely on it for affordable care.

The motion to intervene was granted on May 16, 2018, and the Office of the Attorney General's coalition filed its opposition to Texas’ motion for a preliminary injunction on June 7, 2018. Texas’ requested preliminary injunction would harm millions of Americans by taking away vital healthcare services and stripping funding from our nation’s public health system, including funding for work to combat the opioid epidemic.

Timeline of Legal Actions


A diverse group of patient groups, legal experts, economists, medical associations, and public health experts, have filed amicus briefs in Texas et al. v. United States et al. supporting California’s opposition to Texas and 19 other states’ motion seeking to halt the operation of the Affordable Care Act (ACA) nationwide. The Texas-led lawsuit would end the ACA, threatening healthcare coverage for 20 million Americans – including nearly five million in California – and divert billions of dollars in funding for critical healthcare programs and services nationwide. Terminating the ACA would also strip 133 million Americans with pre-existing health conditions of the legal protection against discriminatory cancellation or denial of their health insurance.

A bipartisan group of attorneys general, legal scholars, economists, and all major medical organizations filed amicus briefs in the 5th Circuit in support of California’s coalition. Links to the briefs can be found in our press release
