Legal Research and Writing - Legal Citation

Legal citation refers to a system of rules for citing primary and secondary legal materials (these rules, for example, would require you to put a case name or statute title in italics). In Canada, these rules have been established largely by the Canadian Guide to Uniform Legal Citation (the "McGill Guide"), now in its 10th edition, available in both print and by subscription here on WestlawNext Canada.

The next most significant source of legal citation rules would come from the work of the Canadian Citation Committee, including The Preparation, Citation and Distribution of Canadian Decisions (2 April 2009), edited by Frédéric Pelletier, Ruth Rintoul and Daniel Poulin and available online in PDF. The work of this Committee has established the use of "neutral citation" for case law. See also the British Columbia Court of Appeal Directive called Citation of Authorities. See also Alberta Law Libraries, "Research Guide: Citing Cases."

Aside from those sources, there are a number of online guides that provide examples of how to cite legal materials, including:

Queen's Law Library, Legal Citation
"Chapter 13: Legal Citation" in The Canadian Legal Research and Writing Guide, 2018 CanLIIDocs 161
Douglas College, Guide to Legal Citation

In the United States, the McGill Guide equivalent is The Bluebook, available online here by subscription. However, in part due to the complexity of The Bluebook, the Association of Legal Writing Directors has developed a simpler form of legal citation in the ALWD Guide to Legal Citation.

There is a free, online "close equivalent" to The Bluebook by Peter Martin called Introduction to Basic Legal Citation.

In the United Kingdom, see the Oxford Standard for the Citation of Legal Authorities (OSCOLA), 4th ed (PDF, 58 pages), with more information available on the OSCOLA website.

In Australia, legal writers use the Australian Guide to Legal Citation (AGLC).

On a related note: I highly recommend Butterick's Practical Typography (2d ed) by Matthew Butterick his recommendations on typography and the formatting of legal documents.
