One of the greatest difficulties in creating good legal writing, particularly effective appellate brief writing, is taking voluminous and complex information and distilling it down to a handful of simple points. It is also one of its greatest delights. There are plenty of tools in a writer’s toolbox to achieve the ultimate goal of succinctness, one of which is use of footnotes.
As Bryan Garner puts it, footnotes are resources and stepping-stones for others who are interested in delving more deeply into a subject. (The Redbook, 2nd Ed., p. 135.) When used effectively, footnotes briefly and concisely establish the foundation on which a writer has built new ideas and qualified or replaced old ones. In simple terms, a footnote should be nothing more than a reference point.
