A closing argument is the final speech each side’s lawyer delivers to the judge or jury after all the evidence has been presented at trial. It is the attorney’s last chance to pull testimony, exhibits, and legal standards into a single persuasive story and tell the fact-finder what verdict the evidence supports. In federal criminal cases, the prosecution speaks first, the defense responds, and the prosecution gets a final rebuttal.
What a Closing Argument Does
Closing is the one phase of trial where lawyers get to openly advocate. During witness examination, attorneys extract information through questions and follow strict evidence rules. During closing, they tell a story. They connect the dots between scattered pieces of testimony, explain what the evidence means, and argue why it points to a verdict in their client’s favor.
The practical work breaks into a few core tasks. Attorneys remind the jury of the most important facts and exhibits. They walk through witness testimony that supports their version of events. They frame that evidence against the legal standard the jury will be asked to apply. In a criminal case, the defense will press that the prosecution has not met the high bar of proving guilt beyond a reasonable doubt. In a civil case, the plaintiff’s lawyer will argue the evidence tips at least slightly in their client’s direction, meeting the lower “more likely than not” standard. Both sides also try to expose weaknesses in the other side’s case, pointing to contradictions or gaps.
Closing is also when a good lawyer confronts bad facts rather than hoping the jury forgot them. Ignored during summation, unfavorable evidence tends to loom larger once deliberations begin.
Who Argues First
The side carrying the burden of proof goes first. In a criminal trial, that means the prosecution opens, the defense responds, and the prosecution closes with a rebuttal. Federal Rule of Criminal Procedure 29.1 lays out this three-part sequence explicitly: the government argues, the defense argues, and the government rebuts.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 29.1 – Closing Argument
Civil trials follow the same logic. The plaintiff typically argues first, the defendant responds, and the plaintiff may get a short rebuttal. The prosecution or plaintiff earns that last word because they carry the burden of proof. The rebuttal is narrower than it sounds. It is meant to answer points the defense raised, not to introduce new lines of argument, and judges will cut counsel off for straying.
This sequence creates a strategic problem for the defense. Because the other side speaks both first and last, defense counsel has to anticipate what the rebuttal will say without knowing exactly how it will be framed. Strong defense closings preempt the most obvious rebuttal points so they land with less force when they come.
How It Differs From an Opening Statement
Opening statements and closing arguments are often confused but serve opposite functions. An opening statement happens at the start of trial and previews what each side expects the evidence to show. Attorneys describe the witnesses who will testify and the facts they plan to establish, giving the jury a roadmap. The key limitation is that opening statements are not supposed to contain argument. A lawyer can say “Witness A will testify that the light was red,” but cannot add “and that proves the defendant was reckless.”2United States Courts. Differences Between Opening Statements and Closing Arguments
Closing arguments flip that restriction. Attorneys are free to argue the merits, draw inferences, and tell the jury what conclusions to reach from the evidence.3United States Courts. Guide to Writing Closing Arguments Where an opening previews, a closing persuades.
The Right to Deliver a Closing Argument
Closing argument is not just a trial custom. In criminal cases, the Supreme Court has treated it as a constitutional right. In Herring v. New York (1975), the Court struck down a New York law that let judges in bench trials deny either side the chance to deliver a closing. The Court held that the right to summation is part of the Sixth Amendment right to effective assistance of counsel and that denying it entirely is never harmless error.4Justia. Herring v. New York, 422 U.S. 853 (1975)
The right is to make a closing, not to make one of unlimited length. Judges have broad discretion to impose reasonable time limits and routinely do. In complex cases, each side might get an hour or more. In simpler matters, fifteen or twenty minutes per side is common. Judges can also interrupt a closing to sustain objections or correct misstatements of the evidence.
A party can voluntarily waive closing argument, though doing so is a significant strategic gamble. If the prosecution waives its initial closing in a criminal case, the defense faces a choice: argue anyway, which gives the prosecution the right to deliver a rebuttal, or also waive and let the case go to the jury in silence. Jurisdictions handle this scenario differently.
Rules Attorneys Must Follow
The freedom to argue has real boundaries. Crossing them can trigger an objection, a sharp correction from the judge, or in severe cases a mistrial. The main prohibitions:
- No new evidence. Everything in a closing must come from evidence already admitted or reasonable inferences from it. An attorney cannot introduce a fact, document, or witness the jury never heard about at trial.
- No personal opinions. A lawyer cannot tell the jury “I believe the defendant is lying” or “In my professional opinion, my client is innocent.” The argument has to be about what the evidence shows, not what the attorney personally thinks.
- No appeals to emotion or prejudice. Arguments designed to inflame rather than persuade on the facts are off limits. That includes comments about race, religion, gender, ethnicity, or political views, and general appeals to fear or sympathy unconnected to the evidence.
- No Golden Rule arguments. Attorneys cannot ask jurors to imagine themselves in the shoes of a party or victim. “How would you feel if this happened to your family?” is the classic example. The rule exists because that framing asks jurors to decide based on personal identification rather than evidence.
The Golden Rule prohibition trips up attorneys more than almost any other. The line between a legitimate emotional appeal grounded in evidence and an improper request to identify with a party is genuinely blurry, and judges make close calls on it regularly.
What Happens When an Attorney Crosses the Line
When opposing counsel hears something improper, the standard response is an immediate objection. The judge then decides whether the remark was out of bounds. If it was, the judge usually instructs the jury to disregard the comment. These curative instructions range from a brief direction to ignore the remark to a more detailed admonishment repeated in the final jury charge.
Failing to object at the time matters enormously on appeal. Courts almost always require a contemporaneous objection in the trial record before they will consider a claim of improper argument. Without one, the appellate court will review only for a fundamental miscarriage of justice, a much harder standard to meet.
In extreme situations, improper argument can lead to a mistrial, meaning the entire trial is thrown out and must start over. This is rare because judges prefer less drastic remedies. But when comments are so prejudicial that no instruction to the jury can undo the damage, a mistrial becomes the only option. On appeal, a conviction can also be reversed if the reviewing court finds the improper argument serious enough to have denied the defendant a fair trial.
Timing With Jury Instructions and Deliberation
Closings are closely tied to the jury instructions, which are the judge’s explanation of the legal rules the jury must apply. The timing varies. In federal criminal cases, the judge has discretion to instruct the jury before closing arguments, after them, or both.5Legal Information Institute. Federal Rules of Criminal Procedure Rule 30 – Jury Instructions Federal civil cases follow a similar flexible approach under Rule 51.6Legal Information Institute. Federal Rules of Civil Procedure Rule 51 – Instructions to the Jury
When instructions come before closing, attorneys can tailor their argument to the exact legal language the judge used and point jurors back to specific instructions that favor their side. When instructions come after, the closing works more as a preview of how the jury should think about the law once they hear it. Either way, experienced lawyers craft their closings with the anticipated instructions in mind, because those instructions define what the jury is actually being asked to decide.
Once instructions and closings are complete, the jury retires to a private room to deliberate. Jurors typically receive written copies of the instructions to reference during their discussions. They select a foreperson to organize the conversation, review the evidence, and work toward a unanimous verdict in criminal cases or the required majority in civil cases. The closing argument is the last voice the jurors hear before that door closes behind them, which is why trial lawyers treat it as the most important few minutes of the entire case.
