A sidebar in court is a brief, private conversation between the judge and the attorneys at the judge’s bench, held quietly enough that the jury and the gallery cannot hear it.1United States District Court Central District of California. Sidebar Its purpose is to let the judge and the lawyers work through legal disputes, evidentiary objections, and sensitive topics without exposing jurors to information that could unfairly influence their verdict.
What a Sidebar Looks Like
An attorney usually starts a sidebar by asking the judge, “May I approach the bench?” The judge can say yes or no. Sometimes the judge waves counsel forward instead, when something needs attention right away. Lawyers from both sides take part, and everyone speaks softly enough that the jury cannot follow along. Many modern courtrooms pipe white noise through the speakers during a sidebar to make sure nobody overhears.2United States District Court Eastern District of California. Courtroom Technology
The exchange typically lasts a few minutes. The jury stays in the box, and the trial picks back up as soon as the judge resolves the issue. From the gallery, it looks like a short huddle at the bench with no audible dialogue.
Why Trials Pause for Sidebars
Most sidebars fall into a few recognizable categories.
Evidentiary Objections
This is the single most common reason. When one attorney objects to a question or a piece of evidence, the judge sometimes needs to hear argument from both sides before ruling. Doing that in open court would defeat the point of the objection, because the jury would hear the very information the objecting attorney wants kept out. A sidebar lets both lawyers argue the issue and lets the judge decide without tainting the panel.
Sensitive or Prejudicial Information
Some facts matter to the judge’s decisions but could unfairly prejudice the jury if said aloud. A witness’s criminal history, a plaintiff’s prior lawsuits, or inflammatory photographs that may not be admissible all fit here. A sidebar gives attorneys a way to raise these topics so the judge can rule on admissibility before anything reaches the jury.
Procedural and Scheduling Issues
Not every sidebar is high-stakes. A witness may be running late, an attorney may need to reorder testimony, or the judge may want to sort out the sequence of upcoming evidence. Handling that at the bench is faster than excusing the jury just to talk logistics.
Sidebars in Jury Selection
Sidebars play a particularly important role during voir dire. When a prospective juror discloses something sensitive, like a personal connection to a crime similar to the one on trial, or admits they may struggle to be impartial, the judge often moves the conversation to the bench. That protects the juror’s privacy and keeps their answers from shaping the rest of the pool.
These voir dire sidebars can run longer than trial sidebars. The judge may question the juror directly, and both attorneys weigh in on whether to excuse the juror for cause. Candid answers are far more likely when the other prospective jurors are not listening.
Can the Defendant Attend?
In criminal cases, federal rules require the defendant to be present at “every trial stage, including jury impanelment and the return of the verdict.” The same rules carve out an exception: the defendant need not be present when the proceeding “involves only a conference or hearing on a question of law.”3Legal Information Institute. Federal Rules of Criminal Procedure Rule 43 – Defendant’s Presence Because most sidebars deal with legal arguments about admissibility or procedure, defendants are routinely excluded.
Jury selection is the main exception. When a judge questions a prospective juror at the bench about possible bias, the defendant has a stronger interest in being there to observe demeanor and body language. Some states treat that as a statutory right, and courts have ordered new trials where defendants were excluded from those particular sidebars without waiving the right. A defendant can waive attendance at sidebar conferences, usually by confirming the waiver on the record after talking with counsel.
Are Sidebars On the Record?
They can be either, depending on the judge’s direction and what’s being discussed. Federal transcript formatting guidelines distinguish between the two, using notations like “(At side bar on the record)” and “(Bench conference off the record).”4United States District Court District of Montana. Transcript Format Guidelines
When a sidebar is on the record, the court reporter transcribes the conversation like any other dialogue in the courtroom. Federal law requires court reporters to record all criminal proceedings conducted in open court, and the same applies in civil cases unless the parties and the judge agree otherwise.5Office of the Law Revision Counsel. United States Code Title 28 – 753 An on-the-record sidebar becomes part of the official trial transcript and is available for appellate review.
Off-the-record sidebars are more informal. They usually cover routine logistics or brief clarifications that don’t involve contested legal issues. The court reporter notes that a bench conference happened but does not transcribe the substance. Experienced trial attorneys generally insist on going on the record for any substantive sidebar, because an unrecorded ruling is nearly impossible to challenge on appeal.
When the Judge Moves It to Chambers
If a dispute is too complex or too long for a quick sidebar, the judge may move the discussion to chambers, the judge’s private office next to the courtroom. That requires excusing the jury entirely, which is why judges prefer sidebars for anything that can be resolved in a few minutes.
A chambers conference typically happens when the court needs a full hearing on a contested evidentiary issue, when attorneys need to present detailed legal argument with case citations, or when the subject matter is sensitive enough that even a whispered bench conversation risks the jury catching fragments. The trade-off is time. A chambers conference can run fifteen or thirty minutes, while a sidebar usually wraps up in two or three. Judges tend to use sidebars first and escalate to chambers only when the issue requires it.
