Definition
Strict construction is a method of legal interpretation that confines the meaning of a text to its literal, express language. A court or interpreter applying strict construction takes words in their exact and technical sense, refuses to supply meaning by implication, and declines to extend coverage beyond what the text explicitly states. Equitable considerations — what the drafters may have intended, what policy would suggest, or what would produce a fairer result — play no role.
The doctrine operates most forcefully in two contexts: (1) statutes that impose penalties or restrict individual liberty, where courts have traditionally held that ambiguity should not be resolved against the person subject to the law; and (2) grants of governmental power, where authority not expressly conferred is treated as withheld.
Strict construction sits at one end of a spectrum. At the other end is liberal or broad construction, which permits a court to fill gaps and extend meaning to achieve perceived legislative purpose. Most interpretive questions in modern practice fall somewhere between the poles.

Common Language
Modern common usage (Wiktionary): A narrow interpretation of a law, especially a law that contains ambiguity.
Historical common usage: The term has no distinct pre-legal common meaning. "Strict" in ordinary usage means rigorous, precise, or undeviating. "Construction" in general English means the act of building or, by extension, the way something is interpreted or understood.
The gap between common and legal usage is modest but real. In ordinary speech, "strict construction" sounds like careful, thorough reading — thoroughness being a virtue. In legal usage, the term describes not carefulness but deliberate narrowness: a refusal to go beyond the text even when extension might seem reasonable. A non-lawyer reading "strict construction" may assume the court read the statute more carefully than usual. A lawyer understands it to mean the court refused to read into the statute anything not already on its face.

Common Confusion
Strict construction is frequently conflated with originalism and with textualism, but the three are not identical.
Textualism, associated with modern statutory interpretation debate, focuses on the ordinary public meaning of the text at the time of enactment. It is not inherently narrow — a textualist may reach a broad reading if the ordinary meaning of the words is broad.
Originalism, primarily a constitutional interpretive theory, asks what the text meant to those who ratified it. It can produce either narrow or broad results depending on historical evidence.
Strict construction, by contrast, is a deliberate tiebreaker in favor of narrowness. Where the text is ambiguous, strict construction resolves the ambiguity by taking the more restrictive reading rather than by consulting history, purpose, or ordinary usage.
Researchers should also distinguish strict construction from the rule of lenity, which is a specific application of the strict construction principle in criminal law: ambiguous penal statutes are to be construed in favor of the defendant.

Why It Matters in Research
Researchers encounter strict construction unevenly distributed across legal domains and time periods, and the term's rhetorical function has shifted considerably.
In nineteenth-century sources, strict construction carried strong political valence. Jeffersonian and later states'-rights arguments against federal power routinely invoked strict construction of the Constitution's enumerated powers. When reading cases or treatises from that era, researchers must recognize that "strict construction" was often a political position dressed in interpretive language, not a neutral description of judicial method. Bouvier's redirection to the CONSTRUCTION entry signals this: the concept was contested enough that the leading nineteenth-century law dictionary declined to give it independent treatment.
In statutory interpretation, strict construction traditionally governed penal statutes, tax laws, statutes in derogation of common law, and grants of eminent domain authority. When researching whether a historical statute applied to a particular situation, check whether courts characterized the statute as one demanding strict construction — the characterization often determined the outcome before analysis began.
In constitutional law research, the term largely retreated from professional usage in the twentieth century, replaced by more technically precise frameworks (originalism, textualism, purposivism). When a judge or advocate in a twentieth-century source uses "strict construction," researchers should treat the term as a signal of interpretive preference, not a technical claim about method.
Corpus connections: The relationship between strict construction and federalism arguments is persistent in the Law Mind corpus. Tax materials frequently invoke strict construction in the context of exemptions and exclusions — the canon that tax exemptions are strictly construed appears across centuries. Employment law materials surface strict construction when interpreting the scope of statutory coverage or the limits of regulatory authority.
One trap: "Strict construction" and "strict scrutiny" are entirely different doctrines from different branches of legal analysis. Strict scrutiny is the constitutional equal protection and due process standard of review; it has nothing to do with statutory interpretation. The similarity of the adjective "strict" has confused students and non-specialists in both historical and modern sources.

Historical Dictionary Support
Black's Law Dictionary gives a serviceable core definition: construction "according to its letter, which recognizes nothing that is not expressed, takes the language used in its exact and technical meaning, and admits no equitable considerations or implications." This formulation has remained stable across Black's editions, which is itself informative — the concept has not required redefinition so much as it has required contextualization.
Bouvier's Law Dictionary provides no independent entry, redirecting to the general treatment of CONSTRUCTION and INTERPRETATION. This is significant. Bouvier was comprehensive and politically engaged; his silence on strict construction as a standalone doctrine suggests the term functioned more as a rhetorical label than as a technical term with agreed-upon content. The entry on Construction in Bouvier addresses the full spectrum of interpretive approaches, with strict construction appearing as one named point on that spectrum rather than a doctrine with its own architecture.
Neither historical dictionary addresses the modern debate about whether strict construction is a coherent or defensible interpretive theory, or how it relates to textualism and originalism — questions that became central in the late twentieth century.

Jurisdictional Note
The formal canon that penal statutes are to be strictly construed is recognized across American jurisdictions and in English common law, though its vigor varies. Some state courts apply strict construction robustly to tax exemption statutes; others have softened the rule in favor of purpose-based analysis. Constitutional strict construction as a political doctrine was primarily an American phenomenon with no direct parallel in parliamentary systems.

Encyclopedia Cross-Reference
No single Law Mind Encyclopedia entry is dedicated to statutory interpretation canons. The closest relevant entries are:
- Strict Liability and Abnormally Dangerous Activities — Strict Liability (General Principles) (The Law Mind Torts & Personal Injury Encyclopedia): Note that strict liability and strict construction share the adjective but are wholly unrelated doctrines. Researchers encountering "strict" terminology should confirm which doctrine is at issue before cross-referencing.
- Constructive Receipt Doctrine (The Law Mind Tax Encyclopedia): Illustrates the strict construction canon as applied in tax law, where the scope of income inclusion provisions has historically been interpreted against extension by implication.
