The Free Exercise Clause

The Free Exercise Clause of the First Amendment is a cornerstone of American liberty, guaranteeing that the government cannot prohibit the free exercise of religion. Yet, this seemingly simple promise has generated complex and enduring legal conflicts. Understanding its evolution is crucial because it defines the balance between religious autonomy and the government’s authority to enforce laws for the public good, a tension at the heart of contemporary debates over healthcare, employment, and public accommodations.

The Foundational Protection: Belief vs. Practice

The Free Exercise Clause protects two distinct spheres: religious belief and religious practice. The Supreme Court has consistently held that religious belief is absolute and beyond government reach. You cannot be punished or discriminated against for what you believe, no matter how unorthodox. The protection of religious practice, however, is not absolute. From its earliest interpretations, the Court recognized that actions taken in the name of religion could be regulated if they threatened public safety, health, or morality. This belief-practice distinction established the initial framework: while belief is inviolable, conduct may be subject to government limitation.

For most of the 20th century, the standard for limiting religious practice was strict scrutiny. This is the highest level of judicial review. Under this test, a law that burdened religious exercise could only be upheld if the government proved it was narrowly tailored to achieve a compelling governmental interest. This was a significant shield for religious minorities. For example, in Sherbert v. Verner (1963), the Court applied strict scrutiny to protect a Seventh-day Adventist who was denied unemployment benefits for refusing to work on her Sabbath. The government’s interest in administrative efficiency was not compelling enough to override her religious practice. This "Sherbert test" governed Free Exercise claims for decades, requiring courts to grant exemptions from generally applicable laws unless the government met this heavy burden.

The Watershed Change: Employment Division v. Smith

The legal landscape shifted dramatically with the 1990 case Employment Division, Department of Human Resources of Oregon v. Smith. Two Native American counselors were fired for using peyote, a controlled substance, in sacramental ceremonies of the Native American Church. They were subsequently denied state unemployment benefits. The Court, in an opinion by Justice Scalia, made a pivotal holding: neutral, generally applicable laws that incidentally burden religion do not require the government to satisfy strict scrutiny.

A neutral law is one not motivated by hostility to religion. A generally applicable law applies to everyone, not singling out religious conduct. The Smith Court reasoned that allowing religious exemptions from such laws—like drug prohibitions, zoning codes, or health regulations—would permit individuals to become "a law unto themselves," undermining the rule of law. Instead, the Court ruled that such laws need only satisfy rational basis review, the most deferential level of judicial scrutiny. Under rational basis review, a law is constitutional if it is rationally related to a legitimate government interest. This is a much easier standard for the government to meet. Consequently, Smith greatly reduced the protection for religious practice, leaving religious individuals with little recourse against laws that are not specifically targeted at religion but still significantly interfere with their exercise.

The Legislative Response: RFRA and State-Level Protections

The Smith decision was widely criticized by an unusual coalition of religious and civil liberties groups. In direct response, Congress passed the Religious Freedom Restoration Act of 1993 (RFRA). RFRA’s explicit purpose was to "restore the compelling interest test" as set forth in the Sherbert case. At the federal level, RFRA requires that any federal law or action that substantially burdens a person’s religious exercise must be justified by a compelling governmental interest and be the least restrictive means of furthering that interest. This statutory framework re-imposed strict scrutiny on the federal government.

However, the Supreme Court later held in City of Boerne v. Flores (1997) that Congress could not use RFRA to impose this strict scrutiny standard on state and local laws. This decision was based on principles of federalism, limiting RFRA’s application to the federal government. This created a patchwork of protection: strong strict scrutiny against federal actions, but only the deferential Smith standard against most state laws.

In reaction, many states enacted their own "mini-RFRAs" or interpreted their own state constitutional provisions to provide stronger protection than the federal Smith standard allows. These state constitutional provisions and statutes vary, but many explicitly restore a form of strict scrutiny for religious liberty claims against state and local governments. Therefore, the legal standard applicable to a religious exercise claim today depends heavily on whether the challenged law is federal or state, and if state, what that particular state’s law provides.

Critical Perspectives and Ongoing Tensions

The current framework is the subject of intense scholarly and judicial debate. Critics of the Smith doctrine argue it leaves religious minorities vulnerable to laws that, while neutral on their face, can effectively outlaw central religious practices. They contend that the pre-Smith strict scrutiny balance better honored the First Amendment’s promise by requiring the government to demonstrate a truly vital need before infringing on religious exercise.

Conversely, defenders of Smith warn that a broad exemption regime would create administrative chaos and inequality, allowing religious claims to undermine everything from anti-discrimination laws to public health mandates. They argue that political processes, not courts, are the proper arena for seeking specific accommodations, as evidenced by the legislative passage of RFRA.

This tension was partially addressed in Burwell v. Hobby Lobby Stores, Inc. (2014), where the Court held that the federal RFRA protected closely held corporations from being required to provide contraceptive coverage that violated their owners' religious beliefs. More recently, cases like Fulton v. City of Philadelphia (2021) have highlighted the instability of the Smith framework, with the Court finding ways to rule for religious claimants by emphasizing a law’s lack of perfect generality, while stopping short of formally overturning Smith. The core conflict remains unresolved: how to meaningfully protect religious exercise without granting it a veto over democratic lawmaking.

Summary

• The Free Exercise Clause absolutely protects religious belief, but the protection for religious practice is conditional and has evolved significantly over time.
• The pivotal case Employment Division v. Smith held that neutral, generally applicable laws that burden religious exercise are subject only to deferential rational basis review, not strict scrutiny, dramatically limiting constitutional protection for religious conduct.
• In response to Smith, Congress passed the Religious Freedom Restoration Act (RFRA), which statutorily restores strict scrutiny for religious liberty claims against the federal government, requiring a compelling interest pursued by the least restrictive means.
• While RFRA does not apply to states, many states have adopted their own laws or interpretations of state constitutional provisions that provide stronger protections than the federal Smith standard, creating a varied legal landscape across the country.
• The tension between religious autonomy and uniform law enforcement continues to drive legal and political debates, ensuring the interpretation of the Free Exercise Clause remains a dynamic and contested area of constitutional law.
