Originalism is the view that the United States Constitution should be interpreted according to the meaning its text had at the time it was written and ratified. Proponents hold that judges are bound to apply that original meaning and have no legitimate authority to update or expand constitutional provisions on their own initiative. The viewpoint is widely held among conservative and libertarian legal scholars, a significant portion of the federal judiciary, and is the dominant interpretive philosophy of the current Supreme Court's majority.

The democratic legitimacy argument. Originalists argue that the Constitution derives its authority from the consent of the governed expressed at the moment of ratification. When judges depart from that original meaning to accommodate contemporary preferences, they substitute their own judgment for the democratic will - a form of rule by an unelected elite. As Antonin Scalia put it, a “Living Constitution” is in practice a “dead Constitution,” because it no longer constrains anyone.

The rule of law argument. Law, originalists contend, must be determinate to function as law. If constitutional meaning shifts with evolving social consensus or judicial temperament, there is no stable legal framework - only whatever five justices happen to believe today. Fixed original meaning provides a principled constraint on judicial discretion and preserves the separation of powers.

The amendment argument. The Constitution provides a formal amendment process (Article V) precisely because its framers anticipated the need for change. When judges reinterpret the Constitution to achieve outcomes they prefer, they bypass that process and effectively amend the document without democratic ratification. If the people want the Constitution to mean something new, originalists hold, they should amend it.

The separation of powers argument. Originalists argue that the judiciary's role is to say what the law is, not what it should be. Policymaking belongs to the legislative branch. When courts expand constitutional rights or protections beyond their original scope, they usurp legislative functions and distort the constitutional structure the framers designed.

Although the underlying intuition is as old as American jurisprudence, originalism as a self-conscious interpretive theory emerged most forcefully in the 1970s and 1980s as a reaction to the Warren Court and the perceived judicial activism of decisions like Roe v. Wade (1973). Raoul Berger's Government by Judiciary (1977) and Edwin Meese III's speeches as Attorney General under Reagan in the mid-1980s gave originalism its first systematic public advocacy.

The Federalist Society, founded in 1982, became the primary institutional vehicle for developing and propagating originalist legal thought within law schools and the legal profession. The appointment of Antonin Scalia to the Supreme Court in 1986 gave originalism its most prominent judicial champion.

An important internal evolution occurred in the 1990s and 2000s: the shift from original intent originalism - focused on the subjective intentions of the framers - to original public meaning originalism, focused on what a reasonable, informed reader would have understood the text to mean at ratification. This shift, associated particularly with scholars like Scalia and Lawrence Solum, addressed a key criticism (that intent is unknowable and framers often disagreed) while preserving the core commitment to textual fixity.

Antonin Scalia (1936-2016) - Associate Justice of the Supreme Court from 1986 until his death, Scalia was the most influential judicial proponent of originalism in the modern era. His opinions and writings, particularly A Matter of Interpretation (1997), gave the theory its most accessible and combative public articulation.

Clarence Thomas (b. 1948) - Associate Justice since 1991, Thomas is widely regarded as the most consistently originalist member of the current Court. He has been willing to apply originalism even when it leads to revisiting established precedent, as in his concurrence in Dobbs v. Jackson Women's Health Organization (2022).

Robert Bork (1927-2012) - Federal judge and legal scholar whose failed 1987 Supreme Court nomination became a flashpoint in debates over constitutional interpretation. His book The Tempting of America (1990) remains a foundational originalist text.

Edwin Meese III (b. 1931) - Attorney General under President Reagan whose 1985 address to the American Bar Association, calling for a “jurisprudence of original intention,” helped launch originalism as a public political movement.

Amy Coney Barrett (b. 1972) - Associate Justice since 2020 and former law professor, Barrett is a committed textualist and originalist whose scholarly work engages the theory at a sophisticated academic level.

Randy Barnett (b. 1952) - Georgetown Law professor and libertarian originalist whose work, including Restoring the Lost Constitution (2004), applies original public meaning to expand, rather than restrict, individual rights - particularly the Ninth Amendment and the Privileges or Immunities Clause.

John McGinnis and Michael Rappaport - Law professors who have developed “original methods originalism,” the view that the Constitution should be interpreted using the interpretive methods prevailing at the time of ratification.

Original intent vs. original public meaning. Older originalists focused on the subjective intentions of the framers and ratifiers. Most contemporary originalists have shifted to original public meaning, arguing that it is more objective and legally tractable. Some scholars, including some associated with “original methods” approaches, continue to contest which framework best captures the theory's commitments.

Precedent (stare decisis). A significant internal tension exists over how originalism should treat long-established precedents that are inconsistent with original meaning. Some originalists, including Scalia, argued for substantial deference to settled precedent on institutional grounds. Others, most notably Thomas, argue that an incorrect precedent has no claim on an originalist judge and should be overruled. This debate came to a head in Dobbs.

Libertarian vs. conservative applications. Most politically prominent originalists are conservatives who use the theory to restrain judicial expansion of rights. But a libertarian strand - associated with Barnett, Clark Neily, and the Cato Institute - argues that original meaning actually supports robust protection of unenumerated rights under the Ninth Amendment and stronger limits on government power than conservative originalists typically endorse. These two camps often agree on methodology but reach different conclusions.

New Originalism and construction. Scholars like Jack Balkin (who identifies as a progressive) and Lawrence Solum have argued that original meaning underdetermines constitutional outcomes in many cases, requiring a second step of “constitutional construction” that involves normative judgment. Traditional originalists dispute whether this move is faithful to the theory or simply reintroduces judicial discretion through the back door.

Liquidation. Some originalists, drawing on James Madison, argue that where the original meaning is genuinely ambiguous, longstanding historical practice can “liquidate” (settle) the meaning over time. This view has gained attention but remains contested within originalist circles.
