Overview

Appellate brief writing is the most craft-intensive form of legal writing. The brief is the primary vehicle for persuading an appellate court. In constitutional cases, the quality of the brief can shape the development of the law. This document distills best practices from leading appellate practitioners and legal writing authorities.

The Ten Commandments of Appellate Brief Writing

1. Know the Standard of Review

The standard of review determines the lens through which the court evaluates the lower court’s decision. State it explicitly at the beginning of each argument section. Frame your arguments to take advantage of the applicable standard.

• De novo review (most constitutional questions) = most favorable to appellants
• Abuse of discretion = strong presumption favoring the lower court
• Clearly erroneous = very hard to overcome on factual findings

2. Tell a Compelling Story in the Statement of Facts

The statement of facts is where most appeals are won or lost. Write it as a narrative, not a catalog. Make the reader care about the outcome before they reach the legal argument. Cite the record for every factual assertion.

3. Frame the Issues to Suggest Their Own Answers

The questions presented should be specific enough to identify the issue, but framed from your client’s perspective. A well-drafted question presented makes the correct answer feel obvious.

4. Lead with Your Strongest Argument

Courts and clerks do not always read every word with equal attention. Put your strongest argument first. If you have a dispositive procedural argument and a merits argument, lead with whichever is stronger and more likely to succeed.

5. Use Argumentative Headings

Every heading and subheading should be a complete sentence stating a legal proposition. The table of contents should read as a standalone outline of your entire argument.

Weak: “The District Court Erred” Strong: “The Executive Order Violates the First Amendment Because It Punishes Law Firms for the Viewpoint of Their Speech”

6. State the Rule Before Applying It

For each argument: (1) state the legal standard, (2) cite the controlling authority, (3) apply the standard to the facts, (4) state the conclusion. Do not bury the rule in the middle of a factual discussion.

7. Address Adverse Authority Head-On

Never ignore inconvenient cases or facts. Distinguish them, explain why they do not control, or concede the point and explain why it does not change the outcome. Courts trust advocates who are candid about weaknesses.

8. Edit Ruthlessly

Every word must earn its place. Cut throat-clearing (“It is well established that…”), unnecessary qualifications, redundant citations, and filler. Short sentences are more powerful than long ones. Active voice is stronger than passive.

9. Make the Brief Visually Clean

• Use white space generously
• Keep paragraphs to a manageable length (no more than half a page)
• Use parallel structure in lists and series
• Avoid long block quotations — paraphrase and cite, or extract the key sentence
• Use footnotes sparingly — if it is important, say it in text

10. Proofread Everything

Typos, citation errors, and formatting mistakes undermine credibility. A brief with errors signals carelessness. A brief without errors signals competence.

Common Mistakes in Appellate Briefs

Writing Style for Appellate Advocacy

Clarity

• Use short sentences (average 20-25 words)
• One idea per sentence
• Avoid jargon and legalese when plain English will do
• Define technical terms when first used

Precision

• Say exactly what you mean — no more, no less
• “The statute requires” is better than “the statute seems to suggest”
• Avoid weasel words: “arguably,” “perhaps,” “it could be said that”
• Use strong verbs: “held,” “found,” “established,” “requires,” “prohibits”

Persuasion

• Place your strongest words at the beginning and end of sentences
• Use the rule of three for emphasis (three examples, three reasons, three cases)
• Vary sentence length for rhythm — a short sentence after a long one creates emphasis
• Use transitions to guide the reader: “Moreover,” “Nevertheless,” “For three reasons”

Honesty

• Never misstate a holding, misquote a source, or omit material facts
• Distinguish between holdings and dicta
• Acknowledge adverse authority and explain why it does not control
• The court’s trust in your candor is your most valuable asset

Constitutional Brief Writing — Special Techniques

Original Meaning Arguments

For originalist courts, demonstrate that your interpretation is consistent with the original public meaning of the constitutional text:

• Cite founding-era dictionaries and legal commentaries
• Reference ratification debates and Federalist Papers
• Cite early practice and legislation (the first Congresses’ actions are evidence of original understanding)
• Address any historical counter-evidence

Living Constitutionalism Arguments

For courts receptive to evolving interpretation:

• Trace the development of doctrine from the founding to the present
• Show how the principle at issue has been consistently extended as society progresses
• Cite the “evolving standards of decency” framework (Trop v. Dulles)
• Demonstrate how the principle serves the Constitution’s underlying purposes

Structural Arguments

Arguments about the Constitution’s architecture — how the branches relate to each other:

• Cite the Federalist Papers (particularly Nos. 47, 48, 51 on separation of powers)
• Argue from constitutional design, not just specific text
• Show how the government’s action disrupts the structural balance
• Cite historical practice as evidence of structural understanding
