Legal citation is a crucial skill for law students and practitioners. It provides a standardized way to reference legal sources, enabling readers to verify information and track legal precedents. Proper citation establishes credibility, supports arguments, and helps avoid plagiarism.

Different citation systems exist, with the Bluebook and ALWD manual being the most common in the U.S. These systems outline rules for citing various legal sources, including cases, statutes, and secondary materials. Understanding the components of citations and their proper formatting is essential for effective legal writing and research.

Purpose of legal citation

• Establishes credibility and authority in legal arguments by referencing specific sources
• Enables readers to locate and verify the accuracy of cited information

Components of legal citations

• Form the building blocks of proper legal referencing
• Vary depending on the type of legal source being cited
• Combine to create a unique identifier for each legal document or source

Volume numbers

• Indicate the specific book or compilation containing the cited material
• Typically appear at the beginning of a citation for case reporters or law reviews
• May be omitted for sources published in a single volume or online-only publications
• Can include series designations (2d, 3d) for multi-series publications

Reporter abbreviations

• Represent standardized short forms for legal publications and case reporters
• Include both official (U.S., S. Ct.) and unofficial (F. Supp., A.2d) reporter abbreviations

• Require familiarity with common abbreviations used in legal writing

Page numbers

• Pinpoint the exact location of cited material within a larger document
• Appear at the end of a citation, often preceded by a comma
• May include specific paragraph or section numbers for more precise referencing
• Can use "at" before the page number in certain citation formats

Types of legal sources

• Encompass primary and secondary legal materials used in legal research and writing
• Require different citation formats based on their nature and authority
• Include binding authorities (primary sources) and persuasive authorities (secondary sources)

Case law citations

• Reference judicial opinions and court decisions
• Include party names, reporter information, court, and year of decision
• Format varies for federal and state court decisions
• May require parallel citations in some jurisdictions (official and unofficial reporters)

Statutory citations

• Refer to legislative enactments and codified laws
• Include title or chapter numbers, section symbols, and statutory compilations
• Vary between federal (U.S.C.) and state statutory codes
• May require references to specific editions or supplements for up-to-date citations

Secondary source citations

• Cover legal treatises, law review articles, and other non-binding authorities
• Include author names, titles, publication information, and specific page references
• Format depends on the type of secondary source (book, article, online resource)
• May require additional parenthetical information to explain relevance or content

Citation formats

• Provide standardized structures for referencing legal materials
• Vary based on the type of legal document and citation system used
• Ensure consistency and clarity in legal writing across different jurisdictions

Full citations vs short citations

• Full citations include all necessary information for first-time references
• Short citations (short form) used for subsequent references to the same source
• Id. used for immediate repeat citations to the same source and page
• Supra used for non-consecutive repeat citations, often with a cross-reference

Parallel citations

• Provide references to the same legal material in multiple sources
• Often required when citing to both official and unofficial reporters
• Separated by commas in most citation formats
• May include parenthetical information to indicate preferred or controlling source

Pinpoint citations

• Direct readers to specific portions of cited legal materials
• Enhance precision in legal writing and argumentation
• Vary in format depending on the type of legal source being cited

Page numbers

• Used for referencing specific pages in books, articles, and case reporters
• Typically appear at the end of a citation, preceded by a comma
• May use "at" before the page number in certain citation formats
• Can include ranges (e.g., 123-125) for citing multiple consecutive pages

Section numbers

• Commonly used for citing specific parts of statutes, regulations, or constitutions
• Often denoted by the section symbol (§) or the word "section"
• May include subsections or paragraphs for more precise referencing
• Can be combined with page numbers in some citation formats

Paragraph numbers

• Utilized for citing specific paragraphs in judicial opinions or other legal documents
• Often enclosed in square brackets or preceded by the paragraph symbol (¶)
• Particularly useful for unpublished or electronically reported cases
• May be combined with page numbers for more comprehensive citations

Parenthetical information

• Provides additional context or explanation for cited materials
• Enhances the reader's understanding of the cited source's relevance
• Appears in parentheses immediately following the citation
• Can include quotes, explanations, or procedural history

Explanatory parentheticals

• Briefly summarize the content or holding of a cited source
• Often begin with present participles (e.g., holding, stating, explaining)
• Should be concise and directly relevant to the point being made
• Can include short quotes or paraphrases of key language from the source

Weight of authority

• Indicates the precedential value or persuasiveness of a cited source
• Uses specific terms (e.g., per curiam, en banc, dictum) to denote authority
• May include information about subsequent treatment of a case (overruled, affirmed)
• Helps readers assess the relative importance of different cited materials

Signal words

• Indicate the relationship between the cited source and the proposition in the text
• Appear at the beginning of a citation, before the authority being cited
• Help readers understand how the writer is using the cited material
• Vary in meaning and usage based on the specific citation system

Common signal words

• See introduces sources that directly support the stated proposition
• E.g. indicates that the cited source is one of multiple examples supporting the point
• Cf. suggests an analogous source that supports the proposition by inference
• But see introduces sources that contradict or challenge the stated proposition
• Contra signals a directly opposing authority or argument

Proper use of signals

• No signal indicates that the source directly states the proposition in the text
• Signals should be italicized in most citation formats
• Multiple signals can be used together, separated by semicolons
• Order of signals typically follows a hierarchy of supportive to contradictory sources
• Improper use of signals can mislead readers about the relationship between text and sources

Electronic source citations

• Address the increasing reliance on digital legal resources in research and writing

• May use permalink or archived versions of webpages for more stable citations
• Often include author, title, and website name in addition to electronic locators

Electronic databases

• Reference commercial legal databases (Westlaw, LexisNexis) and their unique identifiers
• May require specific citation formats provided by the database vendor
• Include database name and document identifier or electronic citation (ECF No.)
• Often allow for parallel citations to print sources when available

Citation in different legal documents

• Adapts citation practices to suit the specific needs and conventions of various legal contexts
