What is an example of an enumerated power?

What the phrase “enumerated powers of congress” means

The term enumerated powers of congress refers to the specific authorities the United States Constitution assigns to the legislative branch, most centrally in Article I, Section 8. The Constitution transcription lists those powers as discrete clauses, and that original 1787 text remains the primary legal baseline for the list of congressional powers, so readers should consult the primary document for the exact language Constitution transcription.

Enumerated powers are meant to be distinct from authorities that belong to the states or to the president. The Constitution assigns Congress specific roles, while reserving other powers to the states or to other branches; this separation helps explain why some authorities are exercised federally and others remain at the state level Constitution Annotated. (See our constitutional rights hub for related context: constitutional rights.)

Where the list appears in the Constitution: Article I, Section 8

Article I, Section 8 of the Constitution is the location where the text lists Congresss enumerated powers clause by clause, beginning with the power to tax and ending with a set of specific authorities related to military and fiscal matters. The clause structure makes it possible to find common items such as taxation, commerce regulation, coinage, and war powers in a single place in the text Constitution transcription. (See a related site overview of Article I: Article I at Constitution Center and our internal guide on Article I: powers of Congress.)

Official legal annotations and modern guides treat Section 8 as the primary source for what counts as an enumerated power and provide context and historical notes that help readers interpret clause boundaries; for a concise, modern annotation consult the Constitution Annotated maintained by the Office of the Law Revision Counsel Constitution Annotated. (For an explainer on the five most important powers see this post.)

Five clear examples of enumerated powers of congress

Overview list: taxation and spending; regulation of interstate commerce; coinage and currency regulation; declaring war; and raising and supporting armies. Each of these appears as a clause in Article I, Section 8 and is routinely cited in constitutional reference materials as a clear example of an enumerated congressional power Constitution Annotated. (See a legal encyclopedia entry on enumerated powers at Federalism Resources: federalism.org.)

Below are brief, one-sentence explanations of each example, with each item tied to the textual clause in Article I, Section 8 so readers can trace the statement to the primary text Constitution transcription.

Power to tax and spend for the general welfare. Article I, Section 8 begins by granting Congress the power to lay and collect taxes and to spend for the general welfare, which forms the textual basis for federal taxation and appropriations authority Constitution Annotated.

Commerce power. The commerce clause authorizes Congress to regulate interstate commerce, a central enumerated power that courts and commentators often treat as a key foundation for national economic regulation Encyclopaedia Britannica on the commerce clause. (For a classroom style overview of Section 8 and the commerce clause see Annenberg Classroom.)

Power to coin money and regulate its value. One clause in Article I, Section 8 gives Congress the authority to coin money and regulate its value, a distinct monetary power assigned to the national legislature Constitution Annotated.

Power to declare war. Article I, Section 8 includes the authority to declare war, a formal congressional power that differs in role from the presidents constitutional role as commander in chief Constitution transcription.

Power to raise and support armies. Congresss clauses on military forces authorize it to raise and support armies and to make rules for their governance, a separate set of enumerated military powers in Section 8 Constitution Annotated.

The commerce clause explained and why it matters

The commerce clause, found in Article I, Section 8, Clause 3, gives Congress the power to regulate commerce among the states and has long been central to federal regulatory authority over interstate economic activity; for a concise overview that places the clause in historical and legal context, consult a standard encyclopedia treatment Encyclopaedia Britannica on the commerce clause.

In practice, the commerce clause matters because courts look to it when deciding whether a federal law addresses interstate economic relations or instead intrudes on matters traditionally left to the states. Over time, judicial interpretation has shaped where the clause draws its boundaries, and modern debates about federal regulation frequently turn on competing readings of the clause and its limits Constitution Annotated.

The power to tax and to spend for the general welfare

Article I, Section 8, Clause 1 grants Congress the power to lay and collect taxes and to provide for the general welfare, language that serves as the textual source for federal taxation and for authorizing spending programs; the clause appears at the start of the enumerated list and is often treated as foundational in the Constitution Annotated Constitution Annotated.

The phrase general welfare has been the subject of interpretation, but for readers seeking a basic guide, the clause establishes that Congress has explicit authority to levy taxes and allocate federal funds within the constitutional framework, and legal commentaries recommend consulting the clause text and official annotations to understand its historical and modern applications Constitution transcription.

The monetary power: coin money and regulate its value

One clause of Article I, Section 8 assigns Congress the power to coin money and to regulate the value thereof, identifying monetary authority as an explicit congressional responsibility and distinguishing it from state monetary powers Constitution Annotated.

War powers: declaring war and raising armies

Article I, Section 8 contains clauses that authorize Congress to declare war and to raise and support armies, giving the legislature clear, textual authority over formal declarations of war and the organization and funding of military forces Constitution Annotated.

These congressional war powers are distinct from the presidents role as commander in chief, a separation of functions that the Constitution establishes by assigning different roles to the branches; readers should consult the text and related annotations when comparing these roles in context Constitution transcription.

Implied powers and the Necessary and Proper Clause

The Necessary and Proper Clause provides that Congress may make all laws which shall be necessary and proper for carrying into execution the foregoing enumerated powers, and courts have held that this clause supports implied powers that supplement but remain tied to the enumerated list McCulloch v. Maryland decision.

In other words, implied powers do not replace the enumerated powers but provide a constitutional bridge that lets Congress enact laws reasonably related to an express power, a principle the Supreme Court articulated in early cases and that remains central to how federal authorities are understood today Wex Legal Encyclopedia on enumerated powers.

Key court decisions that shaped enumerated powers: McCulloch and Gibbons

McCulloch v. Maryland (1819) established that the Necessary and Proper Clause permits implied powers that are necessary to implement the enumerated authorities, a doctrinal foundation often cited when courts assess whether federal action reasonably derives from a listed power McCulloch v. Maryland.

Gibbons v. Ogden (1824) clarified aspects of the commerce power, holding that Congresss authority to regulate interstate commerce includes navigation and national commercial relations, and the case is commonly referenced in discussions about the boundary between federal and state regulatory authority Gibbons v. Ogden.

A simple framework for deciding if a power is enumerated or implied

Step-by-step checklist: first locate the textual clause in Article I, Section 8; second read the official annotation or constitutional commentary; third examine supporting precedent that connects the clause to proposed federal action; fourth consider whether the Necessary and Proper Clause supplies a reasonable link; and finally consult primary sources and legal summaries for close questions Constitution Annotated.

For nonlawyers, this framework emphasizes sourcing: start with the clause text, use reliable annotations for context, and review relevant court decisions rather than assuming an implied outcome. Courts and scholars, not the clause text alone, typically resolve edges of authority in modern disputes Wex Legal Encyclopedia.

Common errors and misconceptions about enumerated powers

A frequent mistake is to treat implied powers as if they were explicitly listed; readers should distinguish between what the Constitution names verbatim and what courts have found to be reasonably implied by those names, and legal reference works offer clear explanations to avoid that conflation Wex Legal Encyclopedia.

Another common error is assuming that an enumerated power automatically guarantees a specific policy outcome; the text grants authority but not a required result, and modern application depends on statutes, judicial interpretations, and political choices rather than the clause wording alone Constitution Annotated.

Practical scenarios: how the five examples appear in modern debates

Commerce clause examples often appear when federal lawmakers or agencies propose rules affecting cross-state business, because those proposals raise questions about whether the activity is properly characterized as interstate commerce and thus within Congresss enumerated authority Encyclopaedia Britannica on the commerce clause.

Taxing and spending powers appear in debates over federal programs and budgets; Congress relies on its Article I, Section 8 authority to levy taxes and to authorize spending, but the scope and design of programs typically rest on statute and judicial interpretation in addition to the clause itself Constitution Annotated.

Primary sources and where to read more

Key primary sources: the Constitution transcription for the exact 1787 language and the Constitution Annotated for modern clause-by-clause explanation; these two are the natural starting points for anyone verifying the textual basis for enumerated powers Constitution transcription.

For landmark court decisions, the McCulloch and Gibbons opinions are recommended reading to understand early judicial interpretation of enumerated and implied powers, and law encyclopedias provide accessible summaries that bridge the cases and doctrine McCulloch v. Maryland.

Brief conclusion: answering “what is an example of an enumerated power?”

A direct example of an enumerated power is Congresss authority to regulate interstate commerce, which is explicitly listed in Article I, Section 8 and commonly cited as a foundational congressional power Constitution Annotated.

Readers should note that the Necessary and Proper Clause and Supreme Court decisions affect how such an example applies in practice, and primary documents and annotated references remain the best sources for verification McCulloch v. Maryland.
