Build a citation you can explain

Opening problem

A paragraph cites Brown, then Anderson, then says “Id. at 495.” The writer intended to return to Brown. The reader follows the immediate reference to Anderson and cannot find the proposition. The writer saved a few words by losing the source.

Learning objectives

Use case-name short forms; apply the immediately-preceding-source requirement for id.; recognize interruption and ambiguity; distinguish supra from case short forms; and audit short references after moving paragraphs.

Short forms depend on context

A full citation establishes an authority's identity. A short form relies on an earlier identification that remains clear to the reader. A reader should be able to expand the short form back to exactly one full citation. If two different full citations fit, the short form has omitted too much.

For a case already identified, a named short form ordinarily retains a distinctive party name, reporter volume, reporter, and an at-pinpoint. The baseline also supplies reporter-only and id. forms in suitable contexts. Our house preference favors a distinctive name after interruption because that makes the source easier to audit. This preference does not create a court rule requiring a name in every short form.

Annotated model

Full citation: Brown v. Bd. of Educ., 347 U.S. 483, 495 (1954).

Named short form: Brown, 347 U.S. at 495.

The short form does not repeat the first page as though it were another pinpoint. It also does not use supra to refer back to the case. The name must remain sufficiently distinctive in the document's actual context. If two cited cases share that name, use more identifying information or repeat a full citation.

Id.: examine the immediate reference

Id. refers to the immediately preceding cited authority under the applicable convention. The reference must be to one identifiable source. If the location is unchanged, Id. can stand alone; a changed location requires the appropriate pinpoint. Do not add a pinpoint unless the source actually has that page, paragraph, or section.

Capitalization depends on placement. Id. begins a citation sentence; id. may occur in an embedded citation context. Italicize the abbreviation and its period. The comma or other surrounding punctuation follows the document's citation-sentence or clause pattern.

After a citation to several authorities, an id. reference can be ambiguous. It is not a general instruction to choose whichever source the author had in mind. Nor does id. jump backward over an intervening authority to a preferred source. A cross-reference that forces a reader to reconstruct the author's mental sequence has failed its purpose.

Editing is a special danger. Moving a paragraph can change the source immediately before id. without changing any characters in the citation. A citation that was sound on Tuesday can refer to a different decision after Wednesday's reorganization. Treat every id. as a context-dependent field during the final document audit.

Worked sequence

First: “The Court rejected segregation in public education. Brown v. Bd. of Educ., 347 U.S. 483, 495 (1954).” Next: “The opinion describes separate educational facilities as inherently unequal. Id.” This sequence cites the same decision and passage. The second citation's identity is clear.

Insert an Anderson citation between those two sentences. The second Id. now follows Anderson, not Brown. Repair it to Brown, 347 U.S. at 495. Repeating the full Brown citation is also acceptable when useful to the reader. Do not preserve the old Id. merely because Brown appears somewhere earlier on the page.

The sentence's proposition still needs verification. A named short form solves identification; it does not prove that the pinpoint supports the sentence. Both tasks remain necessary.

Supra and source-specific limits

Supra means above. Under the practitioner baseline, it supports certain secondary-source cross-references and other eligible materials; do not use it for cases, statutes, constitutions, regulations, Restatements, or model codes. An unusually long case name may need an introduced short name, but that is distinct from permission to use supra.

A book can use an author-based supra reference when an earlier full citation establishes the source and the surrounding context supplies a clear link. A case normally uses its source-specific short form. A statute normally uses its title/code/section or another authorized short form. Do not learn one convenient cross-reference and apply it to every source category.

In practitioner documents, a reference such as “Author, supra, at 20” must actually point to an earlier full citation. Academic note-number systems have their own conventions. This handbook does not assume the document has law-review footnotes. If two works by the same author appear, a surname alone may be insufficient; use a short title or repeat enough information to distinguish them.

Infra points forward and should be used sparingly for internal discussion. A reader who needs the source now should not have to wait for an unidentified citation later. Our chapter links are navigation devices, not substitutes for authority citations.

Names and changing pinpoints

Choose a name that lets a reader recover the correct full citation. Avoid a generic governmental party name when the opposing name is more distinctive. A word that seemed distinctive in one chapter may be shared by several cases in the complete document. Check uniqueness against the whole document rather than a paragraph alone.

When discussing the same case at a different page, retain the source identity and change the pinpoint. If the proposition spans two nonconsecutive pages, identify both locations accurately. When the source is a neutral-citation opinion, use its paragraph pattern rather than importing a reporter-page at form indiscriminately. Source-specific short forms are taught in the corresponding chapters.

Parentheticals and immediate references

An authority mentioned only inside the previous citation’s explanatory parenthetical or history does not necessarily replace its principal source for the id. analysis. Distinguish that subordinate mention from a string citation identifying multiple principal authorities. Our clear-name preference still helps when the final context is uncertain; it is not a claim that every parenthetical forbids id.

Common mistakes and repairs

Compact reference

Before shortening, ask: Has this source been fully identified? Is the proposed short form permitted for this source type? Can this reader locate it unambiguously? Does the pinpoint now support the sentence? For id., add: What is the immediately preceding cited authority after all edits?

Worked editing session: trace a paragraph's short forms

Fictional training example — not legal authority. A draft uses these invented authorities: Vale v. Harbor, 12 Fiction Rep. 100, 104 (Harbor 2024), and N. Pier v. Vega, 20 Fiction Rep. 200, 206 (Harbor Ct. App. 2023). N. abbreviates North in the fictional business's name. Trace the actual sequence rather than the writer's intended sequence.

Replace position 4 with Vale, 12 Fiction Rep. at 104. Restating Vale identifies the source before asking the reader to find the page. Repeating the full citation would also identify it, but the named short form is enough in this supplied context.

Now alter position 1 so that it cites both cases as principal authorities. Position 2 can no longer rely on Id. to select Vale from that pair. Repair position 2 as well: Vale, 12 Fiction Rep. at 105. One inserted authority has changed a later citation even though no character in the later citation was edited.

A subordinate citation inside an explanatory parenthetical or history presents a different relationship. It does not necessarily replace the principal authority for id. Distinguish “A, explaining B” from a citation string presenting A and B as two authorities. Use a clear named form when the surrounding prose leaves their roles uncertain.

Finally, copy positions 2–4 to a new section. Position 2 now begins without its earlier identification. Restore the needed full citation or another clear reference at the new location, then retrace the remaining sequence. Short forms travel with their context; moving only the words can disconnect them from their sources.

Interruption can occur without a full citation

The short-form discussion treats an intervening textual mention of another authority as a potential interruption, even when that mention has no reporter information. The rule does not count only visibly complete citations. Read the words between the prior citation and id. as well as the citation fields.

Fictional training example — not legal authority. A paragraph cites the invented Vale decision, then says “The Harbor Code supplies a different definition,” and finally uses Id. intending Vale. The code reference has introduced another authority. A clear named case short form or a repeated full citation removes the uncertainty. Adding a page number to Id. does not establish which source the writer intended.

The treatment differs for a source mentioned inside the principal citation's explanatory parenthetical. The source rule expressly permits id. to continue referring to the principal source in that situation when the reference remains clear. Do not extend this exception to a new sentence naming a different authority or to a string citation containing two principal authorities. Distinguishing principal and subordinate references is essential to the rule.

Records and long chains

Do not use id. for an appellate record reference such as R. at 22 under the record-citation baseline. Repeating R. at 22 is already short and preserves the source. For other litigation documents, the rule reserves id. for situations where it saves substantial space and remains clear. A declaration is therefore not automatically interchangeable with a judicial opinion for short-form purposes. Chapter 9 supplies document-specific models.

An id. chain can refer back through earlier id. citations, but its usefulness depends on how far the reader must trace. The practitioner discussion treats repetition of a full form after a heading, page break, or an extended chain as a reader-oriented choice; it does not establish a universal five-footnote limit for every practitioner document. Repeat a fuller identification when a section is likely to be read independently. Treat the full citation as part of the reader's access to the source, not as a one-time box checked somewhere in a long file.

Finally, changing a pinpoint from a page to a paragraph changes the locator syntax. Id. at 104 is a page form; Id. ¶ 14 and Id. § 8 are subdivision forms without at. Use the source's supplied coordinates. Shortening the citation must preserve its precise destination.

Source laboratory: two Anderson decisions, two procedural tasks

A document can cite both Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986), and Anderson v. City of Bessemer City, 470 U.S. 564, 573-75 (1985). The names look similar, but the passages address different tasks. Liberty Lobby describes when a factual dispute is genuine for summary judgment. Bessemer City addresses appellate review of a trial court's factual findings under the clearly-erroneous standard.

The second opinion explains that appellate judges cannot reverse merely because they would have weighed the evidence differently. At the same time, page 575 makes clear that calling a determination one of credibility does not insulate it from review when contradictory objective evidence, internal inconsistency, or implausibility supplies grounds for clear error. The supported proposition therefore is neither “appellate courts find facts afresh” nor “factual findings can never be reversed.” Anderson v. City of Bessemer City, 470 U.S. 564, 573-75 (1985).

After introducing both full citations, use distinctive forms: Liberty Lobby, 477 U.S. at 248, and Bessemer City, 470 U.S. at 573-75. Both comply with the reader's need to recover the source. The volumes would distinguish Anderson, 477 U.S. at 248, from Anderson, 470 U.S. at 574, but distinctive party names also make the prose easier to follow when both cases recur.

Now test the sentence as well as the short form. A correct Bessemer City short citation attached to a summary-judgment proposition may still identify the wrong analytical source. The final audit asks two questions: which full citation does this form recover, and does that case address the procedural task described? Citation software may answer the first while leaving the second entirely to you.

Takeaway

A short form succeeds when its context supplies everything you omit. Audit that context again after editing.
