The difference between textualism and purposivism comes down to where a judge looks for a statute’s meaning. A textualist reads the enacted words as a reasonable person would have understood them when the law passed, and stops there. A purposivist treats those same words as the best evidence of what the legislature was trying to accomplish, then reads them in light of that goal, consulting committee reports, floor debates, and the problem the statute was meant to solve. When language is ambiguous, the choice of method often decides the case.
What Textualism Means
Textualism rests on a simple claim about democratic legitimacy: the law is what Congress enacted, and what Congress enacted is the text. A judge’s job is to determine the objective, public meaning of the statutory language at the time it was passed, then apply that meaning. Private intentions of individual legislators are beside the point.
Justice Antonin Scalia drove the modern version of this approach, which scholars call “new textualism,” during his three decades on the Supreme Court. His version was not strict literalism. Scalia accepted that words take meaning from context, that a skilled reader pays attention to how terms relate to each other and to the statute’s overall structure. What a textualist refuses to do is treat a floor speech or a committee report as evidence of what the law means.
That refusal rests on a constitutional argument. Under Article I, a bill becomes law only after both chambers pass it and the President signs it. Committee reports and floor statements never clear that process. Treating them as authoritative, textualists argue, lets a handful of legislators effectively rewrite the law after the fact without the votes the Constitution demands.
Proponents see textualism as a check on judges. If courts stick to enacted text, they cannot smuggle personal policy preferences into a statute under the label of “legislative intent.” The tradeoff is rigidity. Textualism sometimes produces outcomes the judge applying it finds unfortunate, because the text points one way regardless of whether that direction seems wise.
What Purposivism Means
Purposivism starts from a different account of faithful interpretation. The text is the most important piece of evidence about what the legislature was trying to accomplish, but it is evidence, not the whole case. When the plain words lead to a result that conflicts with the law’s evident purpose, a purposivist court looks for the reading that best advances that purpose.
The intellectual foundation for modern purposivism comes from Henry Hart and Albert Sacks, whose legal process materials argued that judges should assume legislators are reasonable people pursuing reasonable goals. Interpretation starts with the text but does not end there. If a literal reading would produce an outcome no reasonable legislator could have intended, the court has both the authority and the obligation to look deeper.
Purposivists work from a wider evidentiary base. Committee reports, hearing transcripts, sponsors’ statements, and the social problem the statute addressed all help a court reconstruct the legislature’s objectives. The goal is to enforce the spirit of the law when the letter falls short. Critics call this an invitation for judges to substitute their own policy views for those of the legislature, since a statute’s purpose can usually be described at several levels of generality. A judge who wants a particular outcome can often frame the purpose to get there.
What Each Method Lets a Judge Look At
The sharpest practical difference between the two methods is the evidence each treats as legitimate. This determines what a lawyer can argue and what a court can rely on.
Intrinsic Sources Both Methods Accept
Both methods accept intrinsic sources, meaning materials found within the statute itself. These include ordinary dictionary definitions, the grammatical structure of the provision, how a term is used elsewhere in the same statute, and the relationship between the provision at issue and surrounding sections. Textualists treat these as the only legitimate tools. If the text is clear after applying them, the inquiry ends.
Textualists also rely on linguistic canons of construction, which are longstanding presumptions about how language works. When a statute lists specific items followed by a general term, for example, courts read the general term as limited to things similar to the listed items. These canons function as educated guesses about how a reasonable drafter would have used language, and textualists lean on them heavily to resolve ambiguity without stepping outside the statute.
Extrinsic Sources Only Purposivists Use
Purposivists draw on materials created outside the enacted text. The most common is legislative history: committee reports explaining the bill, floor debates, hearing testimony, and statements by the bill’s sponsors. These materials help reconstruct what problem the legislature was solving and what outcome it expected the statute to produce.
Textualists object on grounds beyond the constitutional one. Committee reports are often written by staff, not the legislators who voted on the bill. Floor statements may reflect one member’s view, not the body’s collective understanding. And strategic legislators sometimes plant statements in the record specifically to steer future judicial interpretation.
Where the Two Approaches Overlap
The divide is real, but it is not a wall. Several doctrines sit in the space between the two methods, and even committed textualists accept some departures from plain meaning under narrow conditions.
The Absurdity Doctrine
The absurdity doctrine lets a court depart from plain language when applying it literally would produce a result so unreasonable that no legislature could have intended it. It functions as a pressure valve. Even a judge who insists on textualism can avoid an outcome that is genuinely nonsensical. The doctrine represents an implicit concession that enacted words do not always capture what they were meant to say. Purposivists rarely need to invoke it separately, because their broader framework already accounts for absurd results by looking to purpose in the first instance.
Substantive Canons
Beyond linguistic canons, courts use substantive canons that reflect deeper legal values. The rule of lenity requires courts to interpret ambiguous criminal statutes in the defendant’s favor, resting on the principle that only the legislature should define crimes and set punishments. Both textualists and purposivists accept this canon, though they may disagree about when a statute is ambiguous enough to trigger it.
Cases Where the Divide Decided the Outcome
Abstract descriptions only go so far. The cases where these methods collide show what is actually at stake.
Holy Trinity Church v. United States (1892)
A federal statute prohibited anyone from bringing foreign workers into the country “to perform labor or service of any kind.” A church in New York hired an English minister as its rector. The text plainly covered the arrangement. The Supreme Court refused to apply the statute, reasoning that “a thing may be within the letter of the statute and yet not within the statute, because not within its spirit, nor within the intention of its makers.”1Justia Law. Church of the Holy Trinity v. United States, 143 U.S. 457 (1892) The Court looked at the statute’s title, the committee reports, and the social problem Congress was addressing, concluding that the law targeted manual laborers recruited by large employers. Holy Trinity remains the classic illustration of purposivist interpretation, and textualists have spent over a century criticizing it.
Smith v. United States (1993)
Federal law imposed a mandatory sentence on anyone who “uses a firearm” during a drug trafficking crime. John Angus Smith traded a MAC-10 for cocaine. Did he “use” the gun? The majority said yes, relying on dictionary definitions of “use” that include employing something as an item of trade.2Justia Law. Smith v. United States, 508 U.S. 223 (1993) Justice Scalia dissented, arguing that “to use a firearm” ordinarily means to use it as a weapon, and invoking the rule of lenity to resolve the ambiguity in the defendant’s favor. The case shows how two judges committed to text-based reasoning can reach opposite conclusions depending on how they frame “ordinary meaning.”
King v. Burwell (2015)
The Affordable Care Act made tax credits available to people who purchased insurance through “an Exchange established by the State.” Several states declined to create their own exchanges, so the federal government set up exchanges for them. Challengers argued the text was clear: credits were available only through state-created exchanges. The Supreme Court disagreed, holding that reading the phrase in isolation ignored the broader statutory structure. Without credits on federal exchanges, insurance markets in those states would collapse, an outcome the Court concluded “surely could not have been the intention of Congress.” The decision blended textual analysis of surrounding provisions with purposivist reasoning about what the statute was designed to accomplish.
Bostock v. Clayton County (2020)
Title VII prohibits employment discrimination “because of sex.” The question was whether firing someone for being gay or transgender counts as discrimination because of sex. Justice Gorsuch, writing for the majority, applied a textualist framework and concluded that it does. An employer who fires a man for being attracted to men but would not fire a woman for the same attraction has discriminated based on the employee’s sex, because sex was the factor that made the difference.3Supreme Court of the United States. Bostock v. Clayton County, 590 U.S. 644 (2020) The dissenters accused the majority of sailing “under a textualist flag” while updating the statute to reflect modern values. Bostock showed that textualism does not inherently produce conservative results.
Why the Method Matters for Agency Power
This debate is not confined to private disputes over statutory language. It shapes how much power federal agencies have to regulate.
For four decades, courts followed Chevron U.S.A. v. Natural Resources Defense Council, which gave federal agencies significant interpretive authority. If a statute was silent or ambiguous on a question, courts asked only whether the agency’s interpretation was reasonable, not whether the court would have reached the same reading.4Justia Law. Chevron U.S.A., Inc. v. NRDC, 467 U.S. 837 (1984) Chevron deference treated statutory ambiguity as an implicit delegation to the agency. Purposivists were comfortable with that. Textualists were not.
In 2022, the Supreme Court applied what it called the “major questions doctrine” to strike down an EPA rule on power plant emissions. When an agency claims authority to make decisions of “vast economic and political significance,” the Court held, it must point to clear congressional authorization rather than relying on vague or ancillary provisions.5Supreme Court of the United States. West Virginia v. EPA, 597 U.S. 697 (2022) Supporters frame the doctrine as a natural extension of textualism. Critics argue it allows courts to override what the text actually says based on the judge’s sense of how important the issue is.
In 2024, the Court overruled Chevron outright, holding that courts “need not and under the APA may not defer to an agency interpretation of the law simply because a statute is ambiguous.”6Supreme Court of the United States. Loper Bright Enterprises v. Raimondo, 603 U.S. 369 (2024) The decision rested on the Administrative Procedure Act, which directs reviewing courts to “decide all relevant questions of law” and “interpret constitutional and statutory provisions.”7Office of the Law Revision Counsel. United States Code Title 5 Section 706 – Scope of Review Under Loper Bright, judges must exercise their own independent judgment about what a statute means. Courts can still consider an agency’s reasoning as informative. They can no longer treat it as controlling just because the statute is unclear.
How This Plays Out in Practice
For anyone regulated by federal law, the dominance of one method over the other has concrete consequences. Textualism tends to produce narrower readings of regulatory statutes, because the text usually does not spell out every application an agency might envision. After Loper Bright, agencies cannot rely on courts deferring to creative readings of ambiguous language. Regulated businesses have more room to challenge agency rules, and agencies face pressure to seek explicit statutory authority before acting.
Purposivism, when it prevails, tends to give broader effect to remedial statutes, civil rights laws, and consumer protection measures. Courts interpreting those laws purposively look at the problem Congress was addressing and read the statute to cover situations that fit the pattern, even where they do not fit neatly within the literal boundaries of the text. The Holy Trinity approach saves sympathetic defendants from statutes that technically reach their conduct but were not aimed at them. The risk is that it also lets courts rewrite statutes they consider poorly drafted.
Few judges apply either philosophy in pure form. A textualist confronted with a genuinely absurd result will usually find a way around it. A purposivist confronted with clear, unambiguous text will usually follow it, because departing from clear language requires a stronger justification than departing from ambiguous language. Most cases live in the large middle ground of statutes that are neither crystal clear nor hopelessly vague, and that is where the choice of starting point decides which arguments get traction.
