While a federal district court struck down the Affordable Care Act as unconstitutional on December 14, the Act and the litigation will continue. The judge didn’t issue a nationwide injunction which would have had the effect of immediately ceasing all aspects of law.
Unsurprisingly, the states defending the law have stated they will appeal this ruling to the Eleventh Circuit. Particularly if the Eleventh Circuit agrees with the lower court the Supreme Court is likely to hear this case though not until its next term beginning October 2019.
The Affordable Care Act individual mandate required uninsured who didn’t purchase health insurance to pay a so-called shared-responsibility payment. In 2012 the Supreme Court held the individual mandate is a constitutional “exercise of Congress’s Tax Power because it triggered a tax.” The Tax Cuts and Jobs Act of 2017 reduced the tax to $0 as of January 1, 2019.
