OPINION OF THE COURT
The dispositive issue in this appeal is whether the trial court erred in refusing to conduct a limited inquiry to determine whether six jurors participated in the deliberations on *57 all the issues submitted to the jury. Because one juror’s responses during the poll of the jury suggested she may not have participated in all of the jury’s deliberations, we conclude that the order of the Appellate Division must be reversed, the judgment vacated, and a new trial ordered.
Plaintiff Lyndon Sharrow, an iron worker employed by third-party defendant G & H Steel, was injured while using a Genie hoist to move a metal lockbox during construction of the Southport Correctional Facility. He brought this action against defendant Dick Corporation, the general contractor, and defendant Southern Steel Corporation, the subcontractor for the project, alleging common-law negligence and violations of sections 200, 240 (1) and 241 (6) of the Labor Law. Defendants in turn brought a third-party action for contribution and indemnification against G & H Steel, plaintiff’s employer. Prior to trial, Dick and Southern successfully moved for summary judgment against G & H Steel for common-law and contractual indemnification. At trial, plaintiff withdrew all his claims except that for violation of Labor Law § 241 (6) and the action proceeded on that claim alone.
At the conclusion of the jury’s deliberations, the foreperson announced that five members of the jury had agreed to a verdict finding defendants’ violation of the statute the proximate cause of plaintiff’s injuries and awarding him damages in the amount of $430,000. Counsel for G & H Steel requested that the jury be polled. Departing from the usual procedure, the court clerk conducted the poll by reading each question on the verdict sheet and then asking each juror in turn his or her verdict on the question. 1 When the first question was asked— whether there was a violation of the Labor Law for which defendants were liable — juror No. 5 stated that her answer was "No.” The clerk then read the second question — whether the Labor Law violation was a proximate cause of plaintiff’s injuries — and again asked each juror "[w]hat is your verdict?” The transcript reflects juror No. 5’s reply: *58 When the poll on the third question — concerning the total amount of damages necessary to compensate plaintiff— reached juror No. 5, she apparently did not immediately answer. The transcript contains this exchange:
*57 "juror number five: I had no—
"the clerk: Your verdict is no?
"the court: Well, she didn’t make a determination because she didn’t move on [sic]. ”
*58 "the clerk: Number 5? No response?
"juror number five: No.”
To the remaining three questions, involving specific items of damages and of plaintiffs possible negligence, juror No. 5 replied "No response.”
At the conclusion of the polling and before the jury was discharged, counsel for G & H Steel asked to approach the Bench and the court temporarily excused the jury. Counsel identified what he believed to be an inconsistency in the damage amounts stated by the foreperson. He also raised the separate question whether juror No. 5’s answers indicated that she had not voted on any of the questions after the first and may not have participated in the deliberations on any issue other than that of liability. Contending that G & H may have been deprived of a trial by a full jury of six members, counsel requested that the trial court conduct a "very limited questioning of this juror” to determine the extent of her participation in the deliberations. After discussion with all counsel, the trial court denied the request, and judgment was subsequently entered for plaintiff.
The Appellate Division, with two Justices dissenting, modified, by ordering a new trial on the question of damages for pain and suffering, unless defendants stipulated to an additur increasing the amount of that component of the award from $13,000 to $150,000 (
We agree with the Appellate Division dissenters that the trial court erred in refusing to conduct a limited inquiry to determine whether juror No. 5 participated in the verdict process, an error that implicates the constitutional right to a trial by a six-member jury and mandates a new trial.
The common law required a jury of 12 members, and a unanimous verdict

Plaintiff urges that there is "no evidence” here that juror No. 5 did not participate in all the deliberations in this case. That, however, is precisely the reason that the trial court should have conducted the limited inquiry requested, to resolve the doubts engendered by her answers during the poll. The court had the power to inquire into an "imperfect or incomplete” verdict before discharge of the jury
(see, Porret v City of New York,
An inquiry to clarify a verdict before discharging a jury must be distinguished from an attempt to impeach a jury’s verdict after discharge. In considering the propriety of any posttrial inquiry into the validity of a verdict or indictment, the majority of jurisdictions have adopted, either by statute or in case law, the rule embodied in rule 606 (b) of the Federal Rules of Evidence. It directs that a juror may not testify "as to any matter or statement occurring during the course of the jury’s deliberations” except in cases when an inquiry into external influences on the jury is necessary. The policy considerations underlying this rule were first expressed by the United States Supreme Court in
McDonald v Pless
(
The polling process here revealed such an ambiguity. Even if "no response” is considered the equivalent of "no award” in reply to the questions on damages, juror No. 5 also offered "no response” to the question whether plaintiff had been negligent. Her answers raised a legitimate question whether juror No. 5 had participated in the jury’s discussion of issues other than liability, and defense counsel appropriately requested a limited inquiry to clarify that juror No. 5 had participated in the deliberative process.

People v Pickett

Because a Trial Judge has wide discretion in determining whether to send the jury back for further deliberations, had juror No. 5 revealed that she had indeed failed to take part in the entirety of the jury’s deliberations, the trial court could have directed her to do so in a new round of jury deliberations. However, in the absence of any inquiry, the possibility remains that defendants’ constitutional right to trial by a full six-member jury was compromised. Accordingly, we see no remedy but to order a new trial. Moreover, because third-party defendant G & H Steel’s liability is entirely derivative, a new trial must be ordered with respect to the nonappealing defendants as well in order to afford complete relief to the appealing third-party defendant
(see, Cover v Cohen,
Accordingly, the order of the Appellate Division should be reversed, with costs, the judgment vacated and a new trial ordered.
Chief Judge Kaye and Judges Titone, Bellacosa, Smith, Levine and Ciparick concur.
Order reversed, with costs, and a new trial ordered.
Notes
. Customarily, the reported verdict is read to the jury and then each juror is asked: “Is that your verdict?”, to which the juror responds yes or no (see, Supreme and County Court Operations Manual, State of New York, published by Office of Court Administration [Jan. 1991]).
. Although Arizmendi, like this case, involved a unitary trial, the Committee on Pattern Jury Instructions subsequently applied Arizmendi to the more complex bifurcated trial as well, commenting that "[i]f there is a 5-1 vote on liability after the first stage of a bifurcated trial, all jurors, including the liability dissenter, are required to participate in the assessment of damages” (see, 1 NY PJI2d 32-33 [1995 Supp]).
. The Appellate Division majority also relied on the proscription against posttrial juror questioning embodied in Civil Rights Law § 14. However, this statute is generally interpreted as a protection against subjecting a juror to civil or criminal liability for his or her conduct during deliberations or in rendering a verdict
