Arguably the most controversial change to the U.S. healthcare system written into the Patient Protection and Affordable Care Act (“PPACA” or the “Act”) is what has been colorfully termed the Act’s “individual mandate,” the provision that establishes tax penalties for those who do not maintain health insurance in 2014 and beyond. Though the health insurance mandate does not go into effect until 2014, it has already faced numerous constitutional challenges in district and circuit courts, with entirely inconsistent results. Conflicting decisions regarding the Act’s constitutionality at the circuit court level cry out for Supreme Court review. But while the individual mandate’s validity under either the Commerce Clause or Congress’s taxing power has been the focal point of litigation thus far, another aspect of the individual mandate may undermine the goal of establishing universal, affordable healthcare coverage for all Americans. As currently written, the religious conscience exemption from the PPACA’s individual mandate threatens the efficacy of the Act and potentially exposes it to legal challenges under the Constitution’s Religion Clauses.
