The Free Exercise Clause is a broadly worded constitutional prohibition against government intrusion on religious exercise. To construct limits, courts have consistently required government officials to demonstrate the necessity of state action burdening religion. Yet government officials regularly fail to produce evidence of necessity, leaving judges to intuit or assume whether necessity exists. In this Comment, Brady Earley offers a better way. Using a method known as difference-in-differences (DiD), lawmakers can draw upon the experience of existing state laws to enact laws justified with evidence. The Comment demonstrates the value of DiD with a current free exercise controversy involving the Old Order Amish and their objection to Ohio’s flashing light requirement for buggies. Applying DiD to this conflict reveals that Ohio’s buggy light law led to an estimated 23% reduction in buggy-related crashes compared to Michigan and Kentucky—states with less restrictive buggy requirements. Beyond this case study, the Comment also discusses how DiD can help address recent Supreme Court conflicts over tax exemptions for religious organizations, LGBTQ-themed books in schools, and religious charter schools. These examples grapple with the problems and the showcase the possibilities of a data-driven method to address necessity in free exercise.
Freedom of Religion
The rule of law and the rule of God appear to be on a collision course.
Imagine you go to Toronto for a weekend trip with your family. While driving home to Detroit, a border agent pulls you aside, brings you into an isolated room, and asks you, seemingly out of nowhere, “How many times a day do you pray?”
