How to Cite the Constitution in Bluebook Format

Understanding Constitution Citations in Bluebook

The Constitution is the supreme law of the land and a foundational source in all legal writing. Bluebook format provides specific citation rules that distinguish constitutional references from statutes and regulations. Proper constitutional citations indicate the exact provision being discussed and allow readers to understand the constitutional framework.

Basic U.S. Constitution Citation Format

The standard Bluebook format for the U.S. Constitution is: U.S. CONST. art. [Roman numeral], § [number].

Include “U.S. CONST.” in small caps, the article or amendment designation, and the specific section or clause cited.

Article Citation

When citing a specific article of the Constitution:

U.S. CONST. art. I, § 8.

This cites Article I, Section 8 (the enumerated powers of Congress). Use Roman numerals for article numbers.

Amendment Citation

For amendments to the Constitution:

U.S. CONST. amend. XIV, § 1.

Use “amend.” followed by the amendment number in Roman numerals. Section and clause designations follow the amendment number.

Multiple Provisions

When citing several related constitutional provisions:

U.S. CONST. art. I, §§ 8–10.

Use the double section symbol (§§) for multiple sections and specify the range.

Clause Reference

When citing a specific clause within a section:

U.S. CONST. art. II, § 1, cl. 5.

Include the clause abbreviation and number to direct readers to the precise constitutional language.

State Constitution Citation

For state constitutions, use the state abbreviation:

CAL. CONST. art. I, § 1.

TEXAS CONST. art. III, § 25.

Include the state abbreviation in small caps, followed by “CONST.” and the article and section.

In-Text Citations for Constitutional Provisions

In Bluebook legal writing, constitution citations appear in footnotes:

U.S. CONST. art. III, § 2.

For subsequent citations of the same provision, use the shortened form:

U.S. CONST. art. III, § 2.

Examples for Different Constitutional Provisions

First Amendment

U.S. CONST. amend. I.

Fourteenth Amendment, Section 1

U.S. CONST. amend. XIV, § 1.

Commerce Clause

U.S. CONST. art. I, § 8, cl. 3.

Supremacy Clause

U.S. CONST. art. VI, cl. 2.

Fifth Amendment, Due Process Clause

U.S. CONST. amend. V.

Historical Constitutional Versions

When citing earlier versions of the Constitution:

U.S. CONST. art. I, § 8 (original).

Include a parenthetical notation if referring to the original Constitution before amendments, though this is rarely necessary.

Citing Proposed Amendments

For proposed constitutional amendments not ratified:

Proposed Amendment on Flag Desecration, U.S. CONST. amend. (proposed Mar. 22, 2001).

Include parenthetical information indicating the amendment was proposed but not ratified.

Using GenText for Constitution Citations

GenText simplifies constitutional citation in Bluebook format by organizing article numbers, amendment references, and section designations. The tool ensures proper use of Roman numerals and correct abbreviations.

Common Constitutional Abbreviations

Standard abbreviations in constitutional citations:

• U.S. CONST. (United States Constitution)
• art. (article)
• amend. (amendment)
• cl. (clause)
• § or §§ (section or sections)

Finding Constitutional Text

Locating the official Constitution and amendments:

• Congress.gov (legislative.gov)
• National Archives (archives.gov)
• Supreme Court website (supremecourt.gov)
• Legal research databases (Google Scholar, LexisNexis)
• State legislative websites for state constitutions

Common Citation Mistakes

• Using lowercase letters instead of Roman numerals: Always use Roman numerals for articles and amendments (I, II, XIV, not 1, 2, 14).
• Including a year: Constitutional citations do not include a publication year.
• Incorrect abbreviations: Use small caps for “U.S. CONST.” and proper abbreviations for article, amendment, clause.
• Ambiguous references: Always include specific section and clause numbers to prevent confusion.

When to Cite the Constitution

Constitutional citations are essential for:

• Constitutional law analysis
• Discussing fundamental rights
• Interpreting constitutional provisions
• Analyzing Supreme Court decisions
• Examining federalism and separation of powers

Distinguishing Constitutional and Statutory Citations

The Constitution is cited without a year and with Roman numerals. Statutes include publication years and use Arabic numerals. This distinction helps readers understand whether they’re referencing the Constitution or statutory law.

By following Bluebook guidelines for constitutional citations, you correctly reference the foundation of U.S. law and enable readers to understand the constitutional framework underlying your analysis.
