A District of Columbia Court of Appeals Thursday agreed to rehear Halbig v. Burwell, a case charging that the federal government lacks the authority to provide consumers tax credits in health insurance exchanges not run by states. The order agreeing to hear the case technically cancels the three-judge ruling from July that favored the plaintiffs. That ruling, if upheld, could jeopardize the entire structure of the Affordable Care Act by making insurance unaffordable for millions of consumers in the 36 states where the federal government operates the exchange.
