Political Science: US Federal Case Law/Judicial Branch Materials

Case Law

The Judicial branch interprets the law whenever there is confusion or a conflict about its implementation or enforcement. Case law is found in the published, written opinions of judges, and it includes the judge’s decision and the reasoning behind it. Opinions are published in a series called Reporters, which contains the text of opinions arranged chronologically. They are indexed in Digests, which may be broken down by topic and/or geography.

Looking for published court opinions (case law)? Start with Nexis Uni or HeinOnline.

These resources are also useful for finding law review articles, codified laws, and administrative codes. 

News sources to find additional court case information

►Tip: Nexis Uni and HeinOnline only include published court opinions, which means that lower-level court cases (civil cases, trials) are not included. However, news sources can be particularly useful as primary sources that describe events as they unfold, especially for major or historic cases. The Library subscribes to many sources for United States and international news.
