Notes: 

Court cases are not explicitly covered by the IEEE Editorial Style Manual. The formats listed above are based on the format for reports and handbooks since court cases are typically published in court reporters. It is recommended that you check with your instructor to determine how to cite court documents as another style (e.g. Bluebook or Chicago Manual of Style) may provide a more appropriate format. Use the shortened version of the case's title whenever possible; the portions that should be included are often indicated in capital letters in the court document. Also, include an abbreviated name for the court that decided the case as above. If you accessed the case through a library database, provide the name of the database in place of the URL (see p. 40, "U.S. Government Documents: Example," 1); otherwise, provide the direct link to the case.
