A Comprehensive Resource for Strategizing, Writing, & Filing Amicus Briefs

Writing amicus curiae (“friend of the court”) briefs is my favorite activity as an appellate attorney. When I was a Dartmouth freshman, I knew nothing about writing legal briefs. But my “Young Man In American Literature” course taught me how to transform a large volume of thought-provoking material (a different novel each week) into an insightful essay strictly limited to a single, typed page.

Writing an effective amicus brief can be similarly challenging. It’s an art mastered through years of practice. The best amicus briefs are succinct and highly readable. They make a discrete number of points. And they do not duplicate the legal arguments already made by the supported party.

This All Things Amicus page is intended to be a resource for anyone interested in writing or reading amicus briefs.  It provides links to many of my own amicus briefs (most recently for the Atlantic Legal Foundation), as well as to my published articles, commentaries, and presentations about the nuts and bolts of drafting persuasive amicus briefs and using them strategically. There also are links to the Supreme Court’s and federal courts of appeals’ amicus brief rules and guidance. And this page evolves, there will be special features, including my selection of the Amicus Brief of the Month.

How to Draft Effective Amicus Briefs & Use Them Strategically

Amicus curiae briefs are a common as well as important part of appellate practice in the U.S. Supreme Court, federal courts of appeals, and state appellate courts. I had the pleasure of speaking to the Beverly Hills Bar Association on this subject. This one-hour webinar provided practical information for lawyers who either are seeking influential amicus support for clients involved in appeals, or who are called upon to draft persuasive amicus briefs on behalf of trade associations, professional organizations, advocacy groups, or ad hoc coalitions of legal, scientific, or technical experts.

Amicus Brief of the Month logo on attorney Larry Ebner's Capital Appellate Advocacy PLLC law firm website

January 2024

Each month this All Things Amicus page features an amicus brief that was written by another attorney, and in my judgment, is particularly interesting and/or well-written and persuasive.

This month I am featuring the amicus brief submitted to the Supreme Court on January 18, 2024 on behalf of former Attorneys General Edwin Meese, Michael Mukasey, and William Barr in Trump v. Anderson, No. 23-719, the case challenging the Colorado Supreme Court’s disqualification of former President Trump from the Republican presidential primary ballot in that State.

The amicus brief, one of many filed in opposition to the Colorado Supreme Court’s ruling, begins as follows:

“The decision under review is based on a misinterpretation of Section 3 of the Fourteenth Amendment, and would create a precedent with ruinous consequences for our democratic republic. Contrary to the Colorado Supreme Court’s determination, Section 3 does not cover the office of President of the United States. It is also not self-executing. And even a cursory consideration of how such an interpretation could be applied in the future confirms how disastrous it would be to the United States’ form of government. Thus, whatever one thinks of the behavior of former President Trump on January 6, 2021, the Colorado Supreme Court’s decision should be reversed.”
