More than a decade after its enactment, the future of the Affordable Care Act (ACA) remains uncertain as the U.S. Supreme Court takes up another challenge to the law’s constitutionality in California v. Texas (known as Texas v. U.S. in the lower courts). Oral argument is scheduled for Tuesday, November 10, 2020.
The ACA remains in effect while the litigation is pending. However, if all or most of the law ultimately is struck down, it will have complex and far-reaching consequences for the nation’s health care system, affecting nearly everyone in some way.
