Thus far, this guide has described how to cite cases in long form, i.e., how you cite a case for the first time in a document. Because you will often cite a case (and other legal materials) multiple times in a document, The Bluebook has established a "short form" for use in subsequent citations.
The main rule that describes the short form for cases is Rule 10.9. This rule also explains when you can use a short form for cases already cited in full in law review articles. You should consult Bluepages Rule B10.2 for when you can use a short form for cases already cited in full in briefs, filings, and legal memoranda.
In general, a short form for a case has the following elements:
Other short forms are acceptable as long as it's clear which case you are citing. Here are examples of acceptable short forms for Universal City Studios, Inc. v. Corley, 273 F.3d 429 (2d Cir. 2001), assuming you were referencing text on page 435 of the case:
Universal City Studios, Inc. v. Corley, 273 F.3d at 435
Corley, 273 F.3d at 435
273 F.3d at 435
Id. at 435
Id. is used when the case appeared in the immediately preceding citation and the citation included only that case. Like case names, id. can be underlined or italicized. Rule 4 provides additional information on using id.
