What "Writing a Case" Actually Means
A debate case is the prepared document — usually 4 to 8 pages — that contains your side's complete first speech plus the evidence, definitions, and pre-empts that support it. Writing one well is a different skill from speaking well, and most beginners never get explicit instruction in it. The case is what you build before the round; it determines how much heavy lifting you have to do during the round.
The short answer: a working debate case has five components — a clean resolution analysis, two or three contentions built on the claim-warrant-impact structure, integrated evidence with citations, definitions and observations that frame the debate on your terms, and pre-empts for the strongest arguments your opponent will run. Everything else is decoration.
This guide walks through each component in the order an experienced debater actually writes them, with examples drawn from real resolutions across Lincoln-Douglas, Public Forum, Policy, and Parliamentary formats.
Step 1: Analyze the Resolution Before Writing Anything
Most beginners skip this step and start drafting contentions immediately. That is the single biggest case-writing mistake. The resolution is a question — usually phrased as a statement — and your case has to answer that specific question, not a related one you find easier to argue.
Three questions to ask before drafting:
Example: "Resolved: The United States ought to abolish the electoral college."
That last distinction shapes everything that follows. A case that argues "abolishing the electoral college would produce better outcomes" is technically off-topic if the resolution is about moral obligation. Resolution analysis catches that before you waste 4 hours building a misaligned case.
For the deeper version of this step — including the standards and frameworks that LD debaters use to formalize the analysis — see how to prepare for a debate.
Step 2: Select 2-3 Contentions, Not 5
The temptation is to write every argument you can think of. Resist it. Two well-developed contentions beat five shallow ones in every format, and judges consistently say so on ballots.
A contention is one main argument that, on its own, is sufficient to support your side of the resolution. The test is: if a judge bought only this one contention and rejected everything else in your case, would they still vote for you? If yes, it is a contention. If no, it is a sub-point and belongs underneath a contention.
The three-part claim-warrant-impact structure is the spine of every contention:
For a deeper treatment of this framework with examples of structural errors, see how to structure an argument. For the underlying logical structure that distinguishes a real warrant from a restated claim, see the Toulmin model of argument.
Example contention on the electoral college resolution (affirmative):
Contention 1: The electoral college violates political equality.>
Claim: The system creates structurally unequal voting power between citizens, in a way that violates the principle of political equality central to democratic legitimacy.>
Warrant: Wyoming has roughly 3.7 times the per-capita electoral weight of California, because every state receives at least three electoral votes regardless of population. This is not an incidental feature — it is the system functioning as designed. Political philosophers from Rawls to Beitz argue that a procedure giving systematically unequal weight to citizens cannot be justified to the citizens it disadvantages.>
Impact: If political equality is a precondition for democratic legitimacy, and the electoral college violates it by design, then the U.S. has a moral obligation to reform the system. This is the "ought" the resolution asks about.
That single contention, fully developed, is enough to win the round if the negative cannot rebut it. That is the test.
Step 3: Build Definitions and Observations Strategically
Definitions are not neutral. They frame the debate on your terms. The debater who lets the opponent define key terms without contest is fighting on hostile ground from the first speech.
Two rules:
Observations are framing claims that aren't full contentions but that the judge needs to accept for your case to make sense. Examples: "The burden of the affirmative is to defend a topical case, not every conceivable instance of the resolution." "Moral obligations supersede policy preferences when both are present." Observations are short — two or three sentences — and go before contentions.
Step 4: Integrate Evidence Without Drowning In It
Evidence is the difference between an argument that lands and an argument that gets dismissed as opinion. But more evidence is not always better. Three pieces of high-quality evidence, used precisely, beats twelve pieces dumped without analysis.
The evidence sandwich is the integration pattern most experienced debaters use:
Without the analysis step, evidence becomes background noise. The judge does not do the work of connecting your evidence to your claim — you do.
For the methodology of finding good evidence in the first place — including which databases to use and how to evaluate source credibility — see how to research for a debate. The most common evidence error is citing studies that don't actually support the claim being made; for the systematic ways arguments fail logically, see logical fallacies in debate.
Step 5: Write Pre-Empts for the Strongest Opposition Arguments
A pre-empt is a response built into your case to an argument the other side has not yet made. Done well, pre-empts make your case look comprehensive and force your opponent to either run a different argument or run their planned argument knowing you have already addressed it.
Three pre-empts per case is usually right. To find them, ask: "What are the three strongest arguments against my position that any reasonable opponent would make?" Then write 30-60 second responses to each.
Example pre-empt for the electoral college affirmative:
Pre-empt: Federalism objection.>
Negative will likely argue the electoral college protects small-state interests and federalism. Two responses. First, the federalism argument confuses the protection of state interests with the violation of citizen equality — these are distinct values, and the resolution asks about the latter. Second, federalism is already protected through the Senate, where states have equal representation regardless of population. Adding a second federalism mechanism to presidential elections is structural redundancy, not principled federalism.
Pre-empts go at the end of your case, after your contentions, in a section sometimes called "Underview" or "Frontline."
Step 6: Time Out the First Speech Word-for-Word
Cases that look good on paper often run long when read aloud. Before any round, time yourself reading the case at a normal pace. Most formats target a first speech between 3:30 and 8:00 depending on format:
If you are over time, cut, do not speed up. Reading faster than 220 words per minute starts to lose lay judges and reduces the cognitive bandwidth your opponent has to flow your arguments. For why this matters strategically — and how the spreading culture in some Policy and LD circuits has reshaped what cases look like — see how to flow a debate.
A Working Template
Below is the structure most case-writing should follow. The exact section names vary by format and circuit, but the components are universal.
\\\
[Resolution stated verbatim]
[Definitions — only contested terms]
[Observations — 2-3 framing claims]
[Standard / Framework — only LD or value-format cases]
Contention 1: [One-sentence claim] A. Warrant — [Reasoning] B. Evidence — [Citation + quote] C. Analysis — [Connection to claim] D. Impact — [Why this matters]
Contention 2: [One-sentence claim] [Same structure]
[Optional Contention 3]
Underview / Pre-empts: A. [Likely opposition argument 1] — [Response] B. [Likely opposition argument 2] — [Response] C. [Likely opposition argument 3] — [Response]
[Closing line that signposts the standard]

Common Case-Writing Mistakes
Writing the case before researching. You cannot write a strong contention if you don't know what evidence exists for and against it. Research first, draft second.
Repeating the resolution as a contention. "Contention 1: The electoral college should be abolished because it should be abolished" is a real mistake that beginners make in slightly less obvious forms. Each contention has to provide a reason that is independent of the resolution itself.
Burying the impact. If the impact is the last sentence of a long paragraph, the judge will miss it. Lead with it or signpost it explicitly: "The impact is..."
Treating the case as static. Strong debaters revise their case after every round, based on what worked and what got rebutted. The first version of a case is a starting point, not a finished product.
Writing for the format you have, not the round you'll get. A case optimized for tech judges with rapid-fire delivery will lose in front of a community judge who values clarity. If the tournament has mixed judging, write for the most demanding case the judge pool requires.
How to Test a Case Before Using It
The fastest way to find weaknesses in a case is to argue against it yourself. Spend 30 minutes writing the strongest negative case you can imagine. The arguments you generate are the arguments you will face in real rounds — and the holes you find are the ones you can patch before they get exploited.
A second test: read the case aloud to someone outside competitive debate. If they can summarize it back to you in two sentences, the structure is clear. If they can't, the case is doing too much.
The third test is live opposition. AI debate practice on Debate Ladder is built for this — you can run your case in front of an opponent that adapts to your specific arguments, and the immediate feedback tells you which contentions are landing and which are getting cut to ribbons.

Frequently Asked Questions
How long should it take to write a case from scratch? For a topic you've researched, 4-6 hours of focused work for a competitive case. For a brand-new topic, allow 10-15 hours total — most of which is research, not drafting. Cases written in under 2 hours almost always have structural weaknesses that surface in cross-examination.
Should the case be written out word-for-word or as bullet points? Word-for-word for the first speech, bullet points for everything after. The first speech is the only speech you control entirely, so optimizing every sentence is worth the time. Subsequent speeches respond to your opponent and have to be flexible.
How do I write a case for a topic I disagree with? Steel-man it. Find the strongest version of the position, not the weakest. The exercise of arguing positions you disagree with is the single best training for honest argument analysis — for why this matters and how to do it well, see how to win an argument.
Do I need a different case for affirmative and negative? Yes. The affirmative case argues for the resolution; the negative case argues against it (or, in some formats, for a competing alternative). The structure is the same; the contentions are different. Most competitive debaters maintain both, with shared evidence files.
What does a strong case actually look like? Annotated examples are easier to learn from than abstract description. Debate speech examples provides full sample cases across formats with analysis of what makes each one work.
How do I make my case harder to rebut? Cross-apply your contentions. If contention 1 establishes a moral standard and contention 2 establishes a factual claim, write the case so that defeating one does not automatically defeat the other. Independent contentions force the opponent to win two arguments instead of one.
What if my opponent runs an argument I didn't pre-empt? That is what rebuttal speeches are for. Pre-empts handle the predictable arguments; live rebuttal handles the unpredictable ones. For the four-step rebuttal structure used by competitive debaters, see rebuttal examples from competitive debate.
How do I integrate evidence into the case so it actually persuades the judge? The case structure determines where evidence goes; the integration pattern determines whether it lands. Every piece of evidence in your case should follow the Warrant + Evidence + Impact structure — state the warrant in your own words first, cite the source briefly, then state the impact concretely. The full integration patterns, citation conventions across formats, and the comparative-evidence move that wins close rounds are in how to use evidence in a debate.
A well-written case is a force multiplier — it does work for you in every round before you say a word. The investment pays back across an entire season, and the structural skills transfer directly to legal briefs, business cases, policy memos, and any high-stakes written argument.
