Overview

The Religious Freedom Restoration Act of 1993, commonly called RFRA, was enacted after concerns that generally applicable laws could burden religious practice without the demanding justification used in earlier Supreme Court decisions. The federal law established a statutory test for substantial burdens on religious exercise.

This page summarizes the legislative background and later constitutional developments. It is an educational account, not legal advice. The application of RFRA depends on the government action, the facts of a dispute and later case law.

The central test

When government substantially burdens religious exercise, RFRA generally requires the government to show a compelling interest and to use the least restrictive means of furthering that interest, subject to the statute and applicable precedent.

Background

In Sherbert v. Verner (1963) and Wisconsin v. Yoder (1972), the Supreme Court used a demanding balancing approach in important free-exercise disputes. In Employment Division v. Smith (1990), the Court held that a neutral, generally applicable law could usually be applied even when it incidentally burdened religious practice.

Religious organizations and civil-liberties groups with otherwise different priorities formed a broad coalition to seek a legislative response. Congress passed RFRA in 1993, and it was signed into law on 16 November of that year.

The statute stated that its purposes included restoring the compelling-interest test and providing a claim or defense for people whose religious exercise was substantially burdened by government. It also stated that it did not alter the First Amendment’s Establishment Clause.

What the federal act provided

Substantial burden
Government action must not substantially burden religious exercise unless the statutory exception applies.
Compelling interest
The government must identify an interest sufficiently important to justify the burden.
Least restrictive means
The government must select the approach that advances its interest while restricting religious exercise as little as reasonably possible.
Judicial relief
A person could raise a violation as a claim or defense in a judicial proceeding, subject to ordinary standing rules.

The original text attempted to apply these rules to federal and state law. It also defined government broadly and clarified that the statute did not authorize government to burden religious belief or change the Establishment Clause.

The constitutional limit: Boerne v. Flores

The dispute in City of Boerne v. Flores involved a local historic-preservation decision and a church’s proposed building work. The Supreme Court considered whether Congress had authority under the Fourteenth Amendment to impose RFRA’s demanding standard on state and local governments.

On 25 June 1997, the Court held that RFRA exceeded Congress’s enforcement authority insofar as it applied to the states. The decision distinguished between enforcing constitutional rights and redefining the substance of those rights. As a result, the federal statute could not control state and local governments in the same way it controlled federal action.

The ruling did not eliminate the constitutional protection of religious exercise. Instead, it limited RFRA’s reach and prompted many states to consider their own statutory protections. The federal RFRA remains relevant to federal law and federal government action; state questions may depend on state constitutions, statutes and later decisions.

Reactions and practical questions

Supporters viewed RFRA as an important safeguard for minority religious practices and for people whose convictions conflicted with general rules. Critics argued that a broad statutory privilege could make neutral laws harder to administer and could give religious claims an advantage over comparable nonreligious claims.

Cases involving prison rules, employment requirements, land use, health care and public services have illustrated the difficulty of balancing religious exercise with public safety, equal access and the rights of other people. The answer is ordinarily fact-specific: a sincere belief alone does not resolve whether a burden is substantial or whether the government has met the statutory test.

Related federal protections

After Boerne, Congress enacted or relied on more targeted measures. The Religious Land Use and Institutionalized Persons Act, enacted in 2000, addresses certain land-use decisions and restrictions affecting institutionalized people. Its scope and constitutional basis differ from the original nationwide application attempted by RFRA.

Other proposed federal measures sought to replace or supplement RFRA, but legislative proposals do not have the force of enacted law unless passed through the constitutional process.

Why the history still matters

RFRA’s history is a useful case study in religious liberty. It demonstrates that protecting conscience can require careful attention to both individual practice and the institutional limits of government. It also shows why legal summaries should distinguish federal protections from state protections and should avoid treating one court decision as a complete account of current law.
