The Bluebook v. California Style Manual

For many years, the California Style Manual has served as the official guide for styling citations to legal materials in documents filed with state courts in California. Effective January 1, 2008, however, California Rule of Court, Rule 1.200 provides: Citations to cases and other authorities in all documents filed in the courts must be in the style established by either the California Style Manual or The Bluebook: A Uniform System of Citation, at the option of the party filing the document. The same style must be used consistently throughout the document.

Regardless of the citation style used, you should ensure that your citations are formatted consistently in accordance with the rules of the citation style selected as well as any local rules in your jurisdiction that may apply.

Although Rule 1.200 authorizes parties to choose their preferred citation style, some

California courts continue to recommend use of the citation style set forth in the California Style Manual. For those students who will be practicing in firms or appearing before judges that prefer the citation system established by the California Style Manual, a comparison chart showing several rules and examples of commonly used citations in Bluebook and California Style Manual form are provided on the following pages. If your judge or court has not stated a preference for the citation style of the California Style Manual, you may default to the Bluebook citation style.

NOTE: when using the Bluebook style of citation for legal documents, make sure you also refer to the Bluepages in the Bluebook, which may be found at the beginning of the text.
