Definition
Express abrogation is the explicit, direct repeal of a law, provision, or legal rule by a subsequent enactment that specifically refers to the earlier law being repealed. The later law identifies the earlier law by name, citation, or sufficiently clear reference and declares it void, superseded, or otherwise no longer in force.
Express abrogation stands in contrast to implied abrogation (also called implied repeal), where a later law is irreconcilably inconsistent with an earlier one but does not explicitly say so. With express abrogation, there is no interpretive question about whether repeal was intended — the legislature or other enacting authority has said so directly.
The concept applies most commonly in three contexts:
1. Statutory law: A legislature enacts a new statute that expressly identifies and repeals an earlier statute or section thereof.
2. Constitutional law: A constitutional amendment or provision expressly nullifies an earlier constitutional provision. The Eighteenth Amendment's repeal by the Twenty-First Amendment is the textbook example.
3. Common law rules and sovereign immunity: Courts and legislatures may expressly abrogate common law doctrines — most significantly in the sovereign immunity context, where Congress must clearly state its intent to subject the federal government or states to suit.
Common Confusion
Express abrogation is frequently paired with or contrasted against implied abrogation (implied repeal). Researchers should be careful: the two terms describe opposite methods of achieving the same result — the displacement of an earlier law — and historical sources sometimes use "abrogation" alone to mean implied abrogation when discussing conflicts between statutes. The presence or absence of the qualifier "express" is legally determinative, particularly in sovereign immunity doctrine, where courts apply a clear-statement rule requiring express, unambiguous congressional intent before finding that immunity has been waived or abrogated.
Do not conflate abrogation with derogation. Derogation refers to the partial repeal or restriction of a law, whereas abrogation (express or implied) eliminates or fully supplants the prior rule.
Why It Matters in Research
Corpus researchers encounter express abrogation most often in three contexts, each with its own traps.
First, in statutory research, the presence of express abrogation language in a later act is a bright-line signal that the earlier provision is dead — but only as of the effective date of the repealing act. When tracing the development of a legal rule through historical sources, confirm whether the version of a statute in your source predates or postdates the abrogating enactment. Codifications (such as the U.S. Code) frequently incorporate repeals without preserving the original abrogating text, making the repeal invisible unless you consult session law.
Second, in sovereign immunity research, express abrogation carries heightened doctrinal weight. The Law Mind Constitutional Law Encyclopedia entry on abrogation under Section 5 of the Fourteenth Amendment is directly relevant here: Congress's power to abrogate state sovereign immunity under the Fourteenth Amendment requires an unambiguous, express statement of intent, and courts have repeatedly invalidated abrogation attempts where the statutory language was insufficiently clear. When researching pre-1990s materials, be aware that the modern clear-statement rule postdates much of the historical corpus — older sources may describe abrogation analysis in terms that do not reflect the current doctrinal framework.
Third, in common law research, the express abrogation of a common law rule by statute raises questions about preemption and the survival of related common law principles the statute did not specifically address. Historical dictionaries and treatises often treat this as a question of statutory construction, but modern courts have developed distinct frameworks that a researcher should not assume the historical source anticipates.
Cross-corpus note: Express abrogation as a concept connects to implied repeal, derogation, and the general law of statutory interpretation. It also intersects with the canon that statutes in derogation of the common law are to be strictly construed — a canon that cuts against finding abrogation where it is not express.
Historical Dictionary Support
The three shelf sources are in close agreement and essentially define the term identically: express abrogation is abrogation by express provision or enactment, the repeal of a law or provision by a subsequent one referring directly to it. Bouvier's uses the phrase "direct repeal in terms," which captures the same idea with slightly different emphasis — the repeal operates through the language of the repealing instrument itself.
None of the three historical dictionaries address the sovereign immunity context, which is the most consequential modern application of the express abrogation concept. Their definitions are structural — describing the mechanism of explicit legislative repeal — rather than doctrinal. Researchers relying solely on these sources will understand the basic concept but will miss the constitutional dimension that dominates modern usage.
Burrill's cross-reference to "Abrogation" (the parent entry) is worth following; the broader entry addresses the Roman law origins of the concept and the classical distinction between abrogation (total repeal), derogation (partial repeal), and subrogation (substitution), a taxonomy that appears in early American legal writing and may surface in historical corpus materials.
