To cite legal documents, MLA defers to the most recent edition of The Bluebook: A Uniform System of Citation (Cambridge: Harvard Law Rev. Assn.) but stipulates that the references be adapted to MLA Style. Names of cases are italicized in the text, but not in bibliographic references.
Do not italicize the titles of laws, acts and similar documents (such as the Declaration of Independence) in your text or list of works cited.
In your list of works cited, alphabetize a USC entry as if it begins United States Code.
