Case Law Research Guide

WHY FIND A CASE?

Every law student and practicing attorney must be able to find, read, analyze, and interpret case law. Under the common law principles of stare decisis, a court must follow the decisions in previous cases on the same legal topic. Therefore, finding cases is essential to finding out what the law is on a particular issue. This guide will show you how to read a case citation and will set out the sources, both print and online, for finding cases.

For additional information on finding and using cases, read our Digests research guide [http://www.ll.georgetown.edu/guides/digests.cfm] or our online Cases and Digests Tutorial [http://www.ll.georgetown.edu/tutorials/cases/]. For assistance with finding cases, contact the Library's reference librarians [http://www.ll.georgetown.edu/staff/ps/reference/index.cfm].

CITATIONS

A case citation is a reference to where a case (also called a decision or an opinion ) is printed in a book. The citation can also be used to retrieve cases from Westlaw [http://lawschool.westlaw.com] and Lexis [http://www.lexisnexis.com/lawschool/]. A case citation consists of a volume number, an abbreviation of the title of the book or other item, and a page number. For example:

In this example, U.S. is the abbreviation for United States Reports, one place where Supreme Court opinions are published.

Parallel Citations

When the same case is printed in different books, citations to more than one book may be given. These additional citations are known as parallel citations.

Example: 26 U.S. 274, 68 L. Ed. 1016, 44 S. Ct. 565.

This means that the case you would find at page 565 of volume 44 of the Supreme Court Reporter (published by West) will be the same case you find on page 1016 of volume 68 of Lawyers' Edition (published by Lexis), and both will be the same as the opinion you find in the official government version, United States Reports. Although the text of the opinion will be identical, the added editorial material will differ with each publisher.

REPORTERS

The sets of books which publish cases are called reporters , and each one has a designated abbreviation. Reporters may be grouped into four kinds:

1. Federal reporters (report federal cases)
2. Regional reporters (report cases from a group of states)
3. State reporters (report cases from a specific state)
4. Subject reporters (report cases from various jurisdictions which deal a certain area of law, e.g., environment or patents)

Federal, regional, and state reporters are located on the fourth floor.

Federal Reporters

Regional Reporters

State Reporters

Generally a state reporter's abbreviation will include the state's abbreviation (i.e., "Va." is the abbreviation for Virginia Reports, "Md. App." stands for Maryland Appellate Reports .)  Not all states have their own reporters, in which case you must use the Regional reporters. See the pages 188-241 of the Bluebook for further details, or ask a reference librarian.

LEXIS & WESTLAW

All of the cases published in the reporters are also available in full text on Westlaw, and most are available on Lexis, too. Only some of the older state cases may not be available on Lexis. In addition to the full text of cases, Westlaw has PDF images of all cases published in the federal and regional reporters since 1980. Lexis and Westlaw offer case law searching by citation, jurisdiction, and subject.

INTERNET SOURCES

There are many Internet sites that offer the full text of court opinions free of charge. These sites are best used to access recent decisions when the case name, title, or date is known. The Internet is not recommended for precedent research because the sites are not comprehensive and subject searching is not as sophisticated as print, Westlaw, or Lexis.
