Explanation of the Anti-Injunction Act Issue in HHS v. Florida

This short article sorts through and reviews all the arguments surrounding the issue of whether the Anti-Injunction Act, 26 USC §7421 (AIA), bars the federal courts from hearing constitutional challenges to the Patient Protection and Affordable Care Act (ACA). The AIA says that “no suit for the purpose of restraining the assessment or collection of any tax may be maintained in any court by any person.” If the AIA bars this lawsuit, the Supreme Court will not be able to decide whether the ACA is constitutional and the lower court opinions will be vacated. The parties to this case all want the Supreme Court to decide the ACA’s constitutionality. They all argue that the Anti-Injunction Act (AIA) does not bar this lawsuit, but for different reasons. Three amici disagree and argue that AIA bars this lawsuit, but several amici join the parties in arguing that it does not.
