§ 4106.Alternate jurors
Article 41. Trial by a Jury · Last amended 2014 · Last verified July 21, 2026
Full Text of CPLR 4106
Plain-English Summary
Trials can run long, and jurors sometimes cannot finish them: illness, family emergencies, or other unavoidable events can pull a juror out partway through. Section 4106 gives the court a way to plan for that. On a party's request and with the court's consent, one or more alternate jurors are drawn at the same time and in the same way as the regular jurors, meet the same qualifications, and go through the same examination and challenges. Alternates sit with the regular jurors, take the same oath, and are treated no differently throughout the trial, except that they do not take part in deliberations unless called on.
The court can hold onto alternate jurors even after the case has gone to the jury for deliberation, so a replacement is on hand if needed rather than lost the moment the case is submitted. If a regular juror dies, falls ill, or otherwise cannot continue, at any point before or after submission, the court can discharge that juror and bring in an alternate, who then serves as though selected as one of the regular six from the start. Once deliberations are already underway, though, an alternate can only join in if a sitting juror becomes unable to continue, not because the court wants extra insurance on hand.
Frequently Asked Questions
What happens if a juror gets sick during a long New York civil trial?
If an alternate was seated, the court can discharge the juror who cannot continue and bring in the alternate to replace them.
Are alternate jurors chosen the same way as regular jurors?
Yes, they are drawn at the same time, from the same source, and are subject to the same qualifications, examination, and challenges.
Do alternate jurors sit through the whole trial with the regular jury?
Yes, they are seated with the regular jurors, take the same oath, and are treated the same way throughout the trial.
Can an alternate juror join deliberations that have already started?
Only if a regular juror becomes unable to continue serving; otherwise, alternates do not take part once deliberations begin.
Does the court have to use alternate jurors in every trial?
No, alternates are drawn only on a party's request and with the court's consent.
Can the court keep alternate jurors around after the case is submitted to the jury?

Advisory Committee Notes
The Committee recommends the revision of CPLR section 4106 to permit the court in its discretion to retain one or more alternate jurors after final submission of the case to ensure availability if needed during deliberation. The proposed amendment of 4106 also addresses the manner in which the retained alternate jurors may be utilized.
Current 4106 provides that after final submission of the case, “the court shall discharge the alternate jurors”. As a consequence, in the event that a juror becomes disabled during deliberations, the court must declare a mistrial unless all parties consent to proceed with a five person jury, which consent is rarely obtained. In cases of several weeks duration, classically commercial, medical malpractice or products liability cases, a mistrial results in a tremendous waste of time and money for the litigants, the attorneys, and the court, and frustration for the remaining jurors who have served throughout a prolonged trial in an effort to render a verdict. There is a continuing disparity among many courts statewide as to the practice regarding alternate jurors.
The Committee also recommends amendment of 4106 to address the manner in which the retained alternate jurors may be utilized by providing that once deliberations have begun, the court may allow an alternate juror to participate in such deliberations only if a regular juror becomes unable to perform the duties of a juror.
The proposed amendment also makes gender-neutral changes. The Committee appreciates the recommendations of Honorable Philip G. Minardo, former Administrative Judge, Richmond County, regarding the amendment of 4106. Judge Minardo made his recommendations on behalf of and with the support of the New York State Association of Supreme Court Justices and the New York City Association of Supreme Court Justices.

This section is former § 449-a with minor changes. The former requirement that prior to calling one or two alternate jurors, the court must have caused an entry to be made in the minutes to the effect that it appeared that the trial was likely to be a protracted one, has been eliminated. The actual calling of the alternate juror or jurors by the court is a sufficient record of the judge’s decision to that effect, and there appears no need for this formal justification.
The former statute required that the alternate juror or jurors be called, examined, challenged and sworn after the regular jury had been empaneled and sworn. This requirement entails a wasteful and unnecessary duplication of effort. This section provides that the alternates shall be called, examined, challenged and sworn at the same time as the regular jurors.
This section rule makes no change in the former provision that the alternate jurors shall be discharged after final submission of the case. In 1952, § 358-a of the Code of Criminal Procedure, which provides for alternate jurors in criminal trials, was amended to provide that the court, if it deems it advisable at the final submission of the case, may direct that one or more court officers, separate and apart from the regular jurors until the jury has agreed upon a verdict. If, during the deliberations of the jury, a juror dies or becomes ill or is otherwise incapacitated, the court may then order him discharged and substitute an alternate, whereupon the jury renews its deliberations with the alternate juror. While such a procedure has merit, it has not been incorporated in this section. It is only in rare situations that the procedure could be used, and it is believed that an alternate juror who enters the jury room after deliberation has begun is not fully qualified to render an intelligent verdict, having missed part of the discussion and consideration which makes up the deliberative process.
An interesting method of utilizing alternate jurors is in effect in some jurisdictions in both criminal and civil cases. If a protracted trial seems likely, the trial is begun with fourteen jurors. If more than twelve remain at the end of the trial, lots are drawn to determine which twelve comprise the jury which deliberates. See Mass Ann Laws c 234, § 26B (1956); Mich Comp Laws §§ 691.421, 768.18 (1948); NJ Stat Ann § 2A:74-2 (1952).
