Q. How do I write case commentary?
Here are some useful books on how to write a case commentary:
Law School Book: Succeeding at Law School by Allan Hutchinson (on Reserve: Call Number KE289 H88 2000) pages 101-103.
Legal Research and Writing by Ted Tjaden (on Reserve: Call Number KE250 T52 2004) pages 268-270.
Scholarly Writing for Law Students by Fajans and Falk (on Reserve: Call Number KF250 F35 2005) pages 8-11. Appendix A contains a sample casenote.
Lastly, any major Canadian law journal will contain a section devoted to case summaries. For example look in the Canadian Bar Review online.
