Alternate jurors are dismissed at one of two points: right before the jury begins deliberating, or after the jury returns its verdict. Which one depends on the judge, the length of the trial, and how worried the court is about losing a regular juror partway through. In a short, straightforward case, alternates are usually thanked and sent home as soon as closing arguments end and the jury is instructed. In a long or complicated case, the judge often keeps them on standby, available but separated from the deliberation room, until the verdict is read.
The Traditional Point of Dismissal
The default moment is the handoff to deliberations. Closing arguments finish, the judge delivers the final charge, and the alternates are excused before the regular panel retires to the jury room. By that point the alternates have done the job they were seated to do: they stayed ready in case anyone on the regular panel dropped out during trial, and no one did.
The reason for cutting them loose at this stage is structural. Deliberations are meant to involve only the legally required number of jurors, and adding extra people to that room would change the dynamic in ways neither side bargained for. Courts treat the deliberation phase as a closed process, and dismissing the alternates before it starts keeps the line clean.
For the alternate, it can feel abrupt. You sit through every witness, every exhibit, every argument, and then you’re excused before the part that decides the case. That is the trade the role carries. The alternative, keeping unneeded jurors involved in deliberations, raises fairness problems the courts aren’t willing to take on.
When the Judge Keeps Alternates Through Deliberations
In longer or more complex trials, judges often take the other path and retain alternates after the jury retires. The Federal Rules of Criminal Procedure expressly allow it.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors The practical reason is obvious. A trial that took three months to present shouldn’t collapse into a mistrial because one juror catches the flu on day two of deliberations.
Retained alternates don’t sit in on deliberations. They wait separately, usually elsewhere in the courthouse, and the court instructs them not to discuss the case with anyone.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors They stay in that holding pattern until a regular juror has to be replaced or the jury reaches a verdict. Once the verdict is announced and accepted, the alternates are formally discharged.
This approach has become common in cases involving extensive financial records, multiple defendants, or long and emotionally taxing testimony. In federal criminal trials, judges can seat up to six alternates for exactly this kind of insurance.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors
What Happens If an Alternate Gets Called In
An alternate’s dismissal only matters if the alternate wasn’t needed. When a regular juror can’t continue, whether because of a medical emergency, a family crisis, or misconduct like independent research, the judge excuses that juror for good cause and seats an alternate in their place.
If the swap happens during trial, before deliberations begin, the transition is smooth. The alternate has heard the same evidence and simply moves to the regular panel. Trial continues.
If the swap happens after deliberations have already started, federal courts require the jury to begin deliberating from scratch.2Justia. Federal Rules of Criminal Procedure Rule 24 – Trial Jurors Every discussion, every preliminary vote, every argument from before the substitution is set aside. The incoming juror can’t be caught up on where the room left off; they have to participate in the full deliberative process. That restart rule is why alternates kept on standby remain under the same restrictions as regular jurors: no outside discussion, no media, no research. At any moment they may be seated.
Civil Cases Work Differently
If the trial is a federal civil case, there is often no “alternate” to dismiss at all. The formal alternate system in federal civil trials was eliminated in 1991. Instead of designating specific jurors as alternates, courts seat more jurors than the six-member minimum. If anyone has to be excused during trial, the panel simply shrinks. As long as at least six jurors remain, the trial continues and all of them deliberate.3Legal Information Institute.

State courts vary. Many still use designated alternates in both criminal and civil cases; others follow the federal civil approach of seating extra jurors without labeling anyone a backup. If you’ve been seated in a state court case, the local rules control when and whether an “alternate” is formally dismissed.
What Dismissal Means for You
Once the court excuses you as an alternate, your obligation ends. You’re free to leave, to discuss the case, and to talk to attorneys from either side if they approach you. The gag rule you lived under during trial lifts the moment you’re discharged.
Pay stops at dismissal too. Alternates are compensated the same as regular jurors for every day of service, including any days spent waiting on standby during deliberations, but the paid days end when the court lets you go.
Job protection is the one thing that doesn’t end. Federal law makes it illegal for your employer to fire you, threaten you, or retaliate against you for serving on a federal jury, and that protection applies the same way whether you sat through the whole trial as a regular juror or were released as an unused alternate. An employer who violates the law can be hit with civil penalties of up to $5,000 per violation and ordered to reinstate you with no loss of seniority, and the court will appoint an attorney for a retaliation claim that shows probable merit.5Office of the Law Revision Counsel. 28 U.S. Code 1875 – Protection of Jurors Employment Most states have parallel protections for state court service. Being dismissed early as an alternate doesn’t shrink those rights; the days you spent in the courthouse count the same.
