Opening and closing arguments are the two moments in a trial when lawyers speak directly to the jury. An opening statement previews what the evidence will show; a closing argument interprets that evidence after both sides have rested and asks the jury for a verdict. The difference matters because the rules about what an attorney may say are very different in each phase.
What an Opening Statement Is For
After the jury is sworn in, each side delivers an opening statement. The purpose is to give jurors a roadmap of the case: who the key players are, what happened, which witnesses will testify, and what documents or physical evidence will come in.1United States Courts. Differences Between Opening Statements and Closing Arguments
Think of it as a table of contents for the trial. An attorney can tell the jury that a particular witness will testify to a particular fact, but cannot yet argue what that testimony means or why the jury should believe one witness over another. The goal is to prepare jurors to follow the evidence as it comes in, not to persuade them of a conclusion before anything has been heard.
The party with the burden of proof goes first. In a criminal case, that is the prosecution. In a civil case, it is the plaintiff. The defense follows.
What Attorneys Cannot Do During Opening
The core restriction is simple: no arguing. An opening statement must stick to what the evidence will show, not what the jury should make of it.1United States Courts. Differences Between Opening Statements and Closing Arguments An attorney cannot express a personal belief about a witness’s credibility, urge the jury to “send a message,” or make emotional appeals meant to inflame rather than inform. Opposing counsel can object, and the judge will sustain the objection when the lawyer has slipped from previewing into persuading.
Professional ethics add a second limit. Under the professional conduct rules adopted in every state, a lawyer cannot allude to any matter that will not be supported by admissible evidence.2American Bar Association. Rule 3.4 – Fairness to Opposing Party and Counsel Referencing something the court has already excluded by pretrial ruling is a serious violation. In rare cases it leads to a mistrial. That is what happened in the federal perjury prosecution of Roger Clemens, where the judge declared a mistrial during the government’s opening after the prosecutor played a video containing statements the court had already ruled inadmissible.
What a Closing Argument Is For
Once both sides have rested and all the evidence is on the record, the trial shifts to closing arguments. Here the rules invert. Attorneys can finally argue. They can tell the jury what the evidence means, attack the credibility of opposing witnesses, use analogies and hypotheticals, and advocate directly for a verdict.1United States Courts.

Closings also connect the evidence to the jury instructions, which are the legal standards the judge gives the jury for reaching a decision. A plaintiff’s attorney in a negligence case might walk the jury through each element of negligence and point to specific testimony that satisfies it. The defense then explains why the same evidence falls short. This is the phase where individual witness statements and exhibits get woven into a story with a clear ending.
What Attorneys Cannot Do During Closing
Attorneys have far more latitude in closing than in opening, but limits remain. The most important: everything said must be rooted in evidence actually admitted during the trial. A lawyer cannot reference facts that were never presented, no matter how useful they would be.3Legal Information Institute. Closing Argument
Two other prohibitions trip attorneys up regularly. The first is vouching. A lawyer cannot state a personal opinion about a witness’s truthfulness or claim personal knowledge of facts in the case. Saying “I believe this witness told the truth” is improper because it puts the lawyer’s own credibility on the scale alongside the evidence.2American Bar Association. Rule 3.4 – Fairness to Opposing Party and Counsel
The second is the Golden Rule argument. A lawyer cannot ask jurors to imagine themselves in the plaintiff’s or victim’s position and deliver the verdict they would want if they were that person. Courts universally condemn this tactic because it asks jurors to abandon objectivity and decide the case on personal interest rather than the evidence.4Legal Information Institute.

Violations can result in a sustained objection, a curative instruction telling the jury to disregard the remark, or in extreme cases a new trial. The bar for a mistrial is high. The improper comment generally must have been serious enough to prejudice the outcome of the entire trial.
Who Speaks When, and the Rebuttal Problem
The party carrying the burden of proof speaks first and last in both phases. In federal criminal trials, the order is codified: the government argues, the defense argues, and the government rebuts.5Legal Information Institute. Federal Rules of Criminal Procedure Rule 29.1 – Closing Argument
The rebuttal is the final word before the jury deliberates, and its scope is limited. The attorney delivering it can respond to specific points raised in the defense’s closing but cannot introduce brand-new theories. The defense would have no chance to answer, which would be unfair. If the defense waives its closing entirely, the plaintiff or prosecution loses the right to rebut.
A related concern is sandbagging. That is when the prosecution waives its initial closing and saves its entire case for rebuttal, forcing the defense to argue first without knowing what the prosecution plans to say, then denying the defense any chance to respond. Courts in several jurisdictions have recognized this as prejudicial.
Objections and Judicial Remedies
Objections during opening and closing follow the same basic mechanics as objections during testimony, with tighter timing. An attorney who hears opposing counsel cross the line must object immediately. Waiting until after the jury begins deliberating waives the objection.
Common grounds during opening include arguing rather than previewing facts, expressing personal belief about the case, and referencing excluded evidence. During closing, the frequent objections target references to facts outside the evidence, vouching, and Golden Rule appeals.
When a judge sustains an objection, the remedy depends on the severity. For minor slips, the judge may simply stop the attorney and move on. For more damaging remarks, the judge can issue a curative instruction directing the jury to disregard what they just heard, or require the attorney to retract the statement. A mistrial is the most drastic remedy and is reserved for comments so prejudicial that no instruction could undo the damage. Trial judges can also step in on their own when attorney conduct threatens to inflame the jury, even if opposing counsel fails to object.
Visual Aids
Attorneys often use timelines, photographs, diagrams, charts, and digital presentations in both phases. Whether a particular visual is permitted is up to the trial judge. The general standard is that the aid must fairly and accurately represent the evidence without being misleading or inflammatory.
Rules are stricter during opening because no evidence has yet been admitted. An attorney who wants to display a photograph or play a video during opening typically needs the judge’s advance permission and must have a good-faith belief that the item will be admitted later. During closing, attorneys have broader latitude to use demonstrative aids that summarize or illustrate evidence already in the record, such as charts comparing witness testimony, timelines of events, or highlighted excerpts from admitted documents.
Opposing counsel can object to any visual on grounds that it is inaccurate, misleading, or unfairly prejudicial. Judges will sometimes allow a visual for one purpose but prohibit another, permitting a timeline while rejecting a dramatized recreation. The underlying principle is that a visual aid supports the presentation. It does not substitute for actual evidence.
