Avoid stringing together long lists of citations. Prior decisions are tools which are most effective when used with precision, accompanied by a discussion of why the particular case supports the present position of the appellant or appellee. The Conclusion should precisely define the relief requested. Keep the number and length of footnotes to an absolute minimum. If it is possible to write the brief without any footnotes at all, do so.
Footnotes break up the continuity of the argument and are annoying to the reader.
The purpose of the brief is to persuade, not to impress the judges with counsel's scholarship. A brief is not a law review article. Revise the brief several times before filing. Put it aside after finishing the first draft and look at it again a day later from a fresh viewpoint. Ask other attorneys to review it and listen to their advice.
