    PRESENT: Reiber, C.J., Robinson, Eaton and Carroll, JJ., and Wesley, Supr. J. (Ret.),
    Specially Assigned
    ¶ 1.   CARROLL, J.         Defendant, Loren Kandzior, challenges his conviction on one
    count of sexual assault in violation of 13 V.S.A. § 3252(a) on two grounds. First, defendant argues
    that the trial court erred by excluding evidence of a prior false rape allegation. Second, defendant
    argues that his right to a fair trial was violated because the jury was exposed to “extraneous, highly
    prejudicial information”—namely, the substance of an undetermined number of bench conferences
    that occurred during the three-day trial. We conclude that the trial court committed plain error by
    failing to investigate when it became aware that the jury may have overhead numerous bench
    conferences during defendant’s trial. We accordingly vacate defendant’s conviction and remand
    for a new trial.1
    I. Facts
    ¶ 2.    In July 2017, defendant was charged with one count of sexual assault. A three-day
    trial was held in August 2018. On the third day of trial, during defense counsel’s cross-
    examination of the alleged victim, the prosecutor asked to approach the bench. The court
    conducted a bench conference (hereinafter the “specific bench conference”) during which counsel
    discussed the relevance of a particular line of questioning. Immediately after the specific bench
    conference, the prosecutor asked to approach again and informed the court that someone had told
    her that “she could hear everything we were saying” at the bench conferences.2 Defense counsel
    quickly asked the court to instruct the jury to strike anything they may have heard. After an
    indiscernible exchange, defense counsel repeated that she did not “have a problem with [the court]
    just telling [the jury] if they heard us up here, to strike whatever they heard.”
    ¶ 3.    After the bench conference concluded, the court had the following exchange with
    the jury:
    The Court: Jurors, have you all been able to hear us? Yes? Don’t
    pay attention to it.
    Unidentified Juror: Can hear the white noise, but—
    The Court: I don’t understand. I’ve got my hand on the mute
    button. We have the white noise machine. Have you heard us
    throughout the trial? No?
    Unidentified Juror: Yeah.
    The Court: Yes. Some could, yes.
    1
    Because we conclude that the trial court committed plain error by failing to investigate
    the jury taint, we do not address defendant’s argument regarding the prior false rape allegation.
    State v. Dubaniewicz, 
    2019 VT 13
    , ¶ 13 n.2, ___ Vt. ___, 
    208 A.3d 619
    .
    2
    It is not clear from the record who the prosecutor was referring to. Defendant alleges the
    prosecutor was referring to the victim advocate. The State, on the other hand, says only that
    “someone” told the prosecutor. Who exactly the prosecutor was referring to is irrelevant to our
    analysis.
    2
    Unidentified Juror: You can hear noise. I haven’t been able to hear
    what you’re saying.
    The Court: Just shows you how good this equipment is.
    (Indiscernible) wrong. I should turn it off. I don’t know. Okay,
    well, the reason we huddle up here is so you can’t overhear us. So
    you can’t unring the bell, but do the best you can.
    ¶ 4.    Following this exchange, defense counsel did not move for a mistrial. Instead, she
    said “[a]ll right, Judge” and proceeded with her cross-examination of the alleged victim. That
    same day, the jury returned a guilty verdict. Following conviction, defense counsel filed several
    post-trial motions, including a motion for a new trial pursuant to Vermont Rule of Criminal
    Procedure 33. In the motion, defense counsel alleged that the “jury overheard every bench
    conference” and argued that this fact alone entitled defendant to a new trial.
    ¶ 5.    In a written decision and order, the trial court denied the motion for a new trial for
    several reasons. First, the court pointed out that upon learning the jury may have overheard bench
    conferences throughout the trial, the only remedial action defense counsel requested was an
    instruction asking the jury to strike whatever they heard. The court complied and defense counsel
    made no other objection.
    ¶ 6.    Second, the court emphasized that it was not clear what bench conferences the jury
    overheard. The court explained that when it asked the jury members what they heard, they gave
    equivocal answers. Although one juror responded that he heard the specific bench conference, he
    stated that he could not hear what was said. From this response, the court assumed that it was
    unlikely the jury overheard the words spoken at bench conferences because other persons besides
    the jury were in the courtroom—namely, court personnel and trial assistants for the State and
    defendant. Given the presence of these other people, the court concluded that “if the actual
    conversations were overheard, these persons would have called that fact to the [c]ourt’s attention.”
    ¶ 7.    Finally, assuming the jury overheard bench conferences throughout the trial, the
    court concluded that defendant failed to demonstrate he was prejudiced. The court explained that
    3
    many of the bench conferences were not prejudicial. It cited as an example the specific bench
    conference, which “involved only a discussion about what counsel hoped to develop during a line
    of cross-examination.”
    ¶ 8.    Defense counsel moved for reconsideration, arguing that the court should either
    order a new trial or hold an evidentiary hearing to determine what the jurors heard. The court
    denied the motion to reconsider. It concluded that it cured any possible prejudice by instructing
    the jury to strike whatever they may have heard. It also concluded that defendant “waived” his
    right to have the jurors questioned because he did not ask the court to voir dire the jury when he
    learned of the problem. Finally, the court reiterated that defendant was not prejudiced because it
    was “confident that the only bench conference that the jury might have overheard was the ‘specific’
    conference.” Defendant timely appealed.
    ¶ 9.    On appeal, defendant argues that he did not waive his right to a fair trial by an
    untainted jury. Citing State v. Woodard, 
    134 Vt. 154
    , 158, 
    353 A.2d 321
    , 323 (1976), defendant
    argues that “the right to a fair trial by jury is so fundamental that it can be raised at any time.”
    Second, regardless of any action—or lack thereof—taken by defense counsel, defendant maintains
    that “the trial court had an independent duty to investigate the taint.” Moving to the merits,
    defendant argues he is entitled to a new trial because the record establishes that an irregularity
    occurred—i.e., the jurors overheard bench conferences throughout the trial—that had the capacity
    to affect the verdict. Alternatively, defendant argues that under the plain-error standard, “[t]he
    mere capacity for extraneous influence upon the jury warrants reversal.”
    ¶ 10.   In response, the State argues that defendant waived the jury-taint claim because he
    did not immediately move for a mistrial. “Nothing in Vermont law,” the State asserts, “suggests
    that defense counsel’s conduct cannot operate as a waiver of further investigation into juror taint.”
    Regardless, on the merits, the State contends that the trial court correctly determined that a new
    trial was not required. The State emphasizes that the record is unclear as to which bench
    conferences the jury heard and, assuming the jurors heard the bench conferences, it disputes their
    4
    prejudicial nature. Alternatively, the State argues that the case should be remanded for a hearing
    to determine what the jurors heard.
    ¶ 11.   Because defense counsel did not immediately move for a mistrial upon learning
    that the jury may have overheard various bench conferences, the jury-taint claim was not
    preserved. Nevertheless, we hold that the trial court committed plain error by failing to voir dire
    the jury when it learned of the possible jury taint. Without a voir dire, the trial court lacked an
    evidentiary basis to determine whether defendant was prejudiced.              We accordingly vacate
    defendant’s conviction and remand for a new trial.
    II. Analysis
    ¶ 12.   Defendant argues that the trial court erred in denying his post-trial motion for a new
    trial because the jury heard highly prejudicial, extraneous information. Rule 33 permits the trial
    court, on motion from a defendant, to “grant a new trial . . . if required in the interests of justice.”
    The decision on a motion for a new trial “is normally entrusted to the discretion of the trial court.”
    State v. McKeen, 
    165 Vt. 469
    , 472, 
    685 A.2d 1090
    , 1092 (1996). Under the abuse-of-discretion
    standard, “a claim of error can be supported only where the trial’s court discretion was either totally
    withheld, or exercised on clearly untenable or unreasonable grounds.” State v. Messier, 
    2005 VT 98
    , ¶ 15, 
    178 Vt. 412
    , 
    885 A.2d 1193
    .
    ¶ 13.   Where a defendant fails to timely move for a new trial, however, we review for
    plain error. See 
    Woodard, 134 Vt. at 156
    , 353 A.2d at 322 (assuming that defense counsel failed
    to raise issue before trial court and reviewing for plain error). Plain error consists of “glaring error
    so grave and serious that it strikes at the very heart of the defendant’s constitutional rights.” State
    v. Oscarson, 
    2004 VT 4
    , ¶ 27, 
    176 Vt. 176
    , 
    845 A.2d 337
    (quotation omitted). “To reverse on
    plain error, we must find not only that the error seriously affected substantial rights, but also that
    it had an unfair prejudicial impact on the jury’s deliberations.”
    Id. 5 ¶
    14.    We conclude that defendant failed to timely move for a mistral and review for plain
    error. Nevertheless, we conclude that this is one of the “rare and extraordinary cases” where plain
    error occurred. State v. Turner, 
    145 Vt. 399
    , 403, 
    491 A.2d 338
    , 340 (1985).
    A. Preservation
    ¶ 15.    The trial court denied the post-trial motion for a mistrial in part because the only
    remedial action defense counsel requested was an instruction asking the jury to strike whatever
    they heard. The court elaborated on this reasoning in denying the motion to reconsider, explaining
    that defendant “waived” his right to have the jurors questioned because defendant did not ask the
    court to voir dire the jury when he learned of the problem.
    ¶ 16.    Although the trial court used the word “waived,” defendant’s failure to timely move
    for a mistrial is a preservation—not a waiver—issue. While often used interchangeably, waiver
    and preservation are different concepts. Preservation refers to whether a litigant specifically raised
    an issue with the trial court, thereby giving the court “a fair opportunity to rule on it.” State v.
    Ben-Mont Corp., 
    163 Vt. 53
    , 61, 
    652 A.2d 1004
    , 1009 (1994). The “purpose of the preservation
    rule is to ensure that the original forum is given an opportunity to rule on an issue prior to our
    review.” In re White, 
    172 Vt. 335
    , 343, 
    779 A.2d 1264
    , 1270-71 (2001); see also State v. Griffin,
    
    152 Vt. 41
    , 44, 
    563 A.2d 642
    , 644 (1989) (explaining that raising issues before trial court gives it
    an opportunity to take “remedial action” that could “minimize or eliminate any prejudice”).
    ¶ 17.    Waiver, on the other hand, “is the intentional relinquishment or abandonment of a
    known right.” United States v. Olano, 
    507 U.S. 725
    , 733 (1993) (quotation omitted). “[O]ur
    decisions authorize a defendant to waive virtually any right, constitutional or statutory, as long as
    the waiver is knowing, intelligent, and voluntary.” State v. Hance, 
    157 Vt. 222
    , 224, 
    596 A.2d 365
    , 366 (1991); see also 
    Olano, 507 U.S. at 733
    (“Because the right to trial is waivable, and
    because the defendant who enters a valid guilty plea waives that right, his conviction without a
    trial is not ‘error.’ ”).
    6
    ¶ 18.    Here, although the trial court referred to waiver, it was discussing preservation.
    The court denied the motion for a new trial in part because defendant did not timely move for a
    mistrial or ask the court to voir dire the jury and therefore did not preserve his jury-taint claim.
    The parties’ briefing is less than precise and similarly employs the word waiver. The parties appear
    to agree, however, that the issue on appeal is one of preservation. Defendant argues that “the right
    to a fair trial by jury is so fundamental that it can be raised at any time.” The State, citing a series
    of cases from other jurisdictions, appears to argue that unpreserved jury-taint claims should be
    treated no differently than other unpreserved claims—that is, failure to preserve leads to plain-
    error review.
    ¶ 19.    We agree with the State that defendant failed to preserve his jury-taint claim. “A
    defendant cannot gamble on a favorable verdict, but must make prompt objection and motion for
    mistrial.” State v. Bartlett, 
    137 Vt. 400
    , 405, 
    407 A.2d 163
    , 166 (1979). Accordingly, a defendant
    must timely move for a mistrial upon learning of possible jury taint. See 
    Bartlett, 137 Vt. at 405
    ,
    407 A.2d at 166 (holding that juror-misconduct claim was unpreserved because “defendant did not
    move for a mistrial when the facts about [the juror] became known”)3; Silva v. Stevens, 
    156 Vt. 94
    , 111, 
    589 A.2d 852
    , 862 (1991) (holding that jury-taint claim was unpreserved because
    defendants “failed to object to the court’s curative instruction at trial”).
    ¶ 20.    State v. Woodard does not, as defendant suggests, hold that jury-taint claims can
    be raised at any time. Rather, in Woodard, the Court assumed that defendant did not preserve a
    jury-taint claim and engaged in plain-error review. 134 Vt. at 
    156, 353 A.2d at 322
    . In sum, to
    preserve a jury-taint claim, a defendant must timely move for a mistrial.
    ¶ 21.    In this case, defendant did not move for a mistrial when he learned that the jury
    may have overheard various bench conferences throughout trial. In fact, defendant did not move
    for a mistrial until after he was convicted. But, as we have previously cautioned, “[a] defendant
    3
    In Bartlett, despite using the word waiver, we were addressing a preservation issue.
    7
    may not gamble on a favorable verdict before urging prejudicial conduct as grounds for a mistrial.”
    State v. Curtis, 
    145 Vt. 552
    , 553, 
    494 A.2d 143
    , 144 (1985). Because defendant did not timely
    move for a mistrial, the jury-taint claim was not preserved. We accordingly review for plain error.
    B. Plain Error
    ¶ 22.   Vermont Rule of Criminal Procedure 52(b) provides that “[p]lain errors or defects
    affecting substantial rights may be noticed although they were not brought to the attention of the
    court.” However, “raising a plain error argument on appeal is not a substitute for raising a timely
    objection below and it should not be used as such.” State v. Erwin, 
    2011 VT 41
    , ¶ 14, 
    189 Vt. 502
    , 
    26 A.3d 1
    . “If this Court were indiscriminately to entertain claims of error which defense
    counsel expressly—perhaps, strategically—declined to pursue before the trial court, it would
    encourage counsel, at times when correction is simple, to convey the impression that all is well
    while preparing to seek reversal in the event of an adverse verdict.” 
    Turner, 145 Vt. at 403-04
    ,
    491 A.2d at 340-41.
    ¶ 23.   Plain error consists of “glaring error so grave and serious that it strikes at the very
    heart of the defendant’s constitutional rights.” Oscarson, 
    2004 VT 4
    , ¶ 27. “To reverse on plain
    error, we must find not only that the error so seriously affected substantial rights, but also that it
    had an unfair prejudicial impact on the jury’s deliberations.”
    Id. In determining
    whether plain
    error occurred, we are guided by “cases where we have applied the abuse-of-discretion standard.”
    See State v. Ray, 
    2019 VT 51
    , ¶ 9, ___ Vt. ___, 
    216 A.3d 1274
    . The “more concrete federal plain-
    error test” is also a helpful “guide for applying our own plain-error standard.” State v. Yoh, 
    2006 VT 49A
    , ¶¶ 39-40, 
    180 Vt. 317
    , 
    910 A.2d 853
    .
    ¶ 24.   Both the United States and Vermont Constitutions guarantee the right to trial by an
    impartial jury. U.S. Const. amend. VI; Vt. Const. ch. I, art. 10. “This right is coterminous under
    the United States and Vermont Constitutions.” State v. Johnson, 
    2013 VT 116
    , ¶ 14, 
    195 Vt. 498
    ,
    
    90 A.3d 874
    . Under the abuse-of-discretion standard, a defendant seeking “a mistrial based on
    alleged jury taint must show that an irregularity—i.e., anything creating any suspicion of
    8
    extraneous influences—had the capacity to influence jury deliberations.” State v. Amidon, 
    2018 VT 99
    , ¶¶ 14-15, 
    208 Vt. 360
    , 
    198 A.3d 27
    (quotation omitted). “If an irregularity is shown . . .
    the opposing party must show that the irregularity in fact had no effect on the jury.” State v.
    Herrick, 
    2011 VT 94
    , ¶ 13, 
    190 Vt. 292
    , 
    30 A.3d 1285
    . Under this abuse-of-discretion standard,
    we “will not readily overturn the trial court’s denial of a motion for new trial.” State v. Richards,
    
    144 Vt. 16
    , 20-21, 
    470 A.2d 1187
    , 1190 (1983). “[A] claim of error can be supported only where
    the trial’s court discretion was either totally withheld, or exercised on clearly untenable or
    unreasonable grounds.” Messier, 
    2005 VT 98
    , ¶ 15.
    ¶ 25.   Our abuse-of-discretion case law underscores the high burden a defendant has in
    demonstrating that a trial court committed plain error in denying a motion for a new trial. We are
    reluctant to overturn a trial court’s denial of a motion for a new trial under the abuse-of-discretion
    standard. See 
    Richards, 144 Vt. at 20-21
    , 470 A.2d at 1190. And although “[a]buse-of-discretion
    is a highly deferential standard of review, . . . plain error is even more highly deferential.” United
    States v. Montez, 
    858 F.3d 1085
    , 1089 (7th Cir. 2017) (quotation omitted).
    ¶ 26.   Having said that, our jury-irregularity case law, including those cases reviewing for
    abuse of discretion, helps illustrate why plain error occurred in this case. When we review a trial
    court’s decision using the jury-irregularity framework, the trial court has investigated the possible
    taint and established the necessary evidentiary basis for determining “if in fact any prejudice has
    been created.” State v. Onorato, 
    142 Vt. 99
    , 106, 
    453 A.2d 393
    , 396 (1982); see also, e.g., State
    v. Mead, 
    2012 VT 36
    , ¶¶ 13-15, 
    192 Vt. 1
    , 
    54 A.2d 485
    (applying jury-irregularity framework
    where trial court conducted post-trial hearing, which included testimony from juror who had
    extrajudicial contact with one of state’s witnesses); Herrick, 
    2011 VT 94
    , ¶ 14 (applying jury-
    irregularity framework because trial court created basis for determining whether prejudice had
    occurred by conducting “general and individual[ized] voir dire of the jury”); State v. FitzGerald,
    
    165 Vt. 343
    , 349-50, 
    683 A.2d 10
    , 15 (1996) (explaining that trial court established “a basis for
    reviewing whether prejudice had been created” in part because it “examined the juror suspected of
    9
    misconduct under oath”); 
    Onorato, 142 Vt. at 106
    , 453 A.2d at 396-97 (applying jury-irregularity
    framework because trial court “exposed the necessary basis . . . through voir dire of the jury”).
    ¶ 27.   When a trial court fails to investigate possible jury taint, however, we cannot apply
    the jury-irregularity framework because the trial court, and this Court on appeal, has no “basis for
    determining if any prejudice exists.” 
    Onorato, 142 Vt. at 106
    , 453 A.2d at 396. We cannot assess
    whether or how a jury was affected if the trial court does not investigate and establish an
    evidentiary basis regarding what the jury may have heard. See 
    Woodard, 134 Vt. at 156
    -58, 353
    A.2d at 323-24. Accordingly, the failure to investigate possible jury taint and establish an
    evidentiary basis for determining if the jury was fair and unbiased amounts to plain error. See,
    e.g.,
    id. (holding that
    trial court committed plain error by failing to investigate possible jury taint);
    
    Onorato, 142 Vt. at 106
    , 453 A.2d at 396 (recognizing principle that when trial court fails to voir
    dire jury, it “lacks a basis for determining if any prejudice exists”); State v. Lafleur, No. 2002-257,
    
    2003 WL 25746029
    , *3 (Mar. 1, 2003) (unpub. mem.), https://www.vermontjudiciary.org/sites/
    default/files/documents/eo02257.pdf [https://perma.cc/5WSF-D2Z6] (concluding that trial court’s
    failure to investigate potential jury taint was plain error because “absent some examination of the
    jury by the trial court upon discovering the possibility of any prejudice, the trial judge lacks a basis
    for determining if any prejudice exists, and consequently this Court has no record from which it
    can determine if the jury was fair and unbiased” (quotation omitted)).
    ¶ 28.   Normally, to reverse on plain error we must determine that the error affected
    defendant’s substantial rights and had a prejudicial impact on the jury. Oscarson, 
    2004 VT 4
    , ¶ 27.
    In Woodard, however, we held that when a trial court fails to investigate possible jury taint, plain
    error occurs regardless of any prejudice. 134 Vt. at 
    156-58, 353 A.2d at 323-24
    . The clear import
    of this case is that the failure to investigate possible jury taint is a structural error that affects
    substantial rights and can be corrected without a specific showing of prejudice.
    ¶ 29.   The United States Supreme Court has speculated that “[t]here may be a special
    category of forfeited errors that can be corrected regardless of their effect on the outcome.” Olano,
    
    10 507 U.S. at 735
    . A majority of federal appeals courts have recognized that one of those categories
    of forfeited error is structural error. See, e.g., United States v. Lockhart, 
    947 F.3d 187
    , 200 (4th
    Cir. 2020) (Wynn, J., concurring) (“Under Rule 52(b) plain-error review, this Court has held that
    . . . structural errors necessarily affect substantial rights . . . .” (quotations omitted)); Arthur v.
    United States, 
    986 A.2d 398
    , 413 (D.C. Cir. 2009) (“[I]f [the error] is structural in nature, the
    defendant’s substantial rights will be deemed to have been affected, without need for further
    analysis in the context of the particular trial.”).
    ¶ 30.   Structural error involves defects that “ ‘affect[] the framework in which the trial
    proceeded, and thus, prevent[] the trial from serving its function as a vehicle for determining the
    guilt or innocence of the defendant.’ ” State v. Muscari, 
    174 Vt. 101
    , 116-17, 
    807 A.2d 407
    , 419
    (2002) (quoting In re Hunt, 
    163 Vt. 383
    , 387, 
    658 A.2d 919
    , 922 (1995)). Structural error is
    distinguished from mere “trial error,” which is error that “occurred during the presentation of the
    case to the jury, and which may therefore be quantitatively assessed in the context of other
    evidence presented in order to determine whether its admission was harmless.” Arizona v.
    Fulminante, 
    499 U.S. 279
    , 307-08 (1991).
    ¶ 31.   This case law makes clear that a trial court’s failure to voir dire the jury after
    learning of the possibility of jury taint amounts to a structural error that affects substantial rights
    without regard to prejudice. When the trial court conducts an investigation into a claim of jury
    taint and establishes an evidentiary basis, we have a record from which we can determine if the
    jury was fair and unbiased. Without this evidentiary basis, however, there is no record from which
    we can determine how the jury was affected. 
    Onorato, 142 Vt. at 106
    , 453 A.2d at 396. In other
    words, structural error occurs because we cannot “quantitatively assess[]” how the jury was
    affected. 
    Fulminante, 499 U.S. at 307-08
    . In this circumstance, “a rule requiring the defendant to
    show prejudice, or one requiring the state to show lack of prejudice, makes no sense.” United
    States v. Noushfar, 
    78 F.3d 1442
    , 1445 (9th Cir. 1996) (quotation omitted).
    11
    ¶ 32.   In sum, we apply two distinct analyses to jury-taint claims depending on whether
    the trial court investigated the possible taint and established an evidentiary basis regarding what
    the jury may have heard. When a trial court investigates possible jury taint, we apply the jury-
    irregularity framework because the trial court has established an evidentiary basis for reviewing
    whether prejudice occurred. 
    FitzGerald, 165 Vt. at 349-50
    , 683 A.2d at 15. When a trial court
    fails to investigate upon discovering the possibility of jury taint, however, plain error occurs
    because there is no basis for determining whether or how the jury was affected. Such failure
    amounts to a structural error that affects substantial rights and can be corrected without a specific
    showing of prejudice.
    ¶ 33.   There are two important caveats to the failure-to-investigate analysis. First, the
    duty to investigate occurs only when the trial court discovers the possibility of jury taint. See, e.g.,
    
    Onorato, 142 Vt. at 105-06
    , 453 A.2d at 396 (explaining that trial court learned of possible jury
    taint when juror told the court that he learned “this was a second trial”); 
    FitzGerald, 165 Vt. at 347
    ,
    
    349-50, 683 A.2d at 14-15
    (explaining that trial court discovered possible jury taint when public
    defender “told the court that one of his clients claimed than an alternative juror had discussed the
    case with neighbors”); 
    Woodard, 134 Vt. at 155-57
    , 353 A.2d at 322-24 (explaining that
    “suspicion” of jury taint arose where jury member told court he heard defendant making
    incriminating statements outside of court).
    ¶ 34.   Second, given the “diverse array of juror-irregularity cases,” Mead, 
    2012 VT 36
    ,
    ¶¶ 14-15, trial courts retain broad discretion in how they choose to investigate possible jury taint.
    Although trial courts must investigate upon discovering possible jury taint, the method and scope
    of investigation depends on the circumstances. Compare 
    Onorato, 142 Vt. at 106
    , 453 A.2d at
    396-97 (holding that trial court established evidentiary basis by conducting voir dire of jury), with
    
    FitzGerald, 165 Vt. at 349-50
    , 683 A.2d at 15 (holding that court did not have “to conduct
    individual voir dire” because it “examined the juror suspected of misconduct under oath”).
    12
    ¶ 35.   In this case, the issue is whether the trial court committed plain error in denying
    defendant’s post-trial motion for a new trial based on alleged jury taint. There is no dispute that
    the trial court was aware of possible jury taint: the prosecutor informed the court that someone had
    told her that “she could hear everything we were saying” at the bench conferences. Based on the
    principles outlined above, the remaining inquiry in our plain-error analysis is whether the trial
    court investigated and established an evidentiary basis to support its conclusion that the jury was
    fair and unbiased. If the court failed to investigate, plain error occurred.
    ¶ 36.   The State argues that the trial court established an evidentiary basis because it made
    an inquiry of the jury and three jurors gave ambiguous responses about what they heard. We
    cannot agree. Although the trial court asked the jurors two questions about what they may have
    heard, this was an insufficient investigation because the trial court, by its own admission, failed to
    establish an evidentiary basis regarding what the jury may have heard.
    ¶ 37.   The court asked the jurors two rather confusing questions about whether they had
    been able to hear the bench conferences throughout the trial. First, the court asked, “have you all
    been able to hear us? Yes? Don’t pay attention to it.” Then the court asked if the jury could hear
    the bench conferences “throughout the trial” and ended the question with, “No?” The record
    indicates that there were three responses from an “Unidentified Juror”: one response was could
    “hear white noise,” another response was “[y]eah,” and a third was you could “hear noise” but
    could not hear what “you’re saying.” Because all three responses are identified as coming from
    an “Unidentified Juror,” we are unable to determine whether these responses came from the same
    juror or multiple jurors. The court did not follow up with any of the jurors to determine what
    exactly they heard.
    ¶ 38.   The court’s denial of defendant’s post-trial motion for a mistrial illustrates the
    inadequacy of the court’s investigation. The court acknowledged that it was “not clear what the
    jury heard” and that it “did not specifically inquire.” Furthermore, the court repeatedly relies on
    speculation about what the jurors could or could not hear. For example, the court says that it
    13
    “doubts that the bench conversation were actually overheard” and was “confident that the jurors
    did not overhear any other bench conferences either before or after the specific bench conference.”
    (Emphasis added.)
    ¶ 39.   “No right is more fundamental to a defendant than a fair trial by jury . . . .”
    
    Woodard, 134 Vt. at 158
    , 353 A.2d at 323. Given the significance of this right, the trial court’s
    limited questioning of the jury, speculation about what the jury may have heard, and “confidence”
    that the jury did not overhear bench conferences do not provide a sufficient record for determining
    “if the jury was fair and unbiased,” 
    Onorato, 142 Vt. at 106
    , 453 A.2d at 396. Indeed, as the trial
    court itself admitted in denying the post-trial motion for a mistrial, “[i]t is not clear what the jury
    heard, either with respect to the specific bench conference or with respect to other bench
    conferences.” Accordingly, we hold that the trial court committed plain error by failing to
    investigate and establish an evidentiary basis regarding what the jury heard.
    Defendant’s conviction is vacated, and the case is remanded for a new trial.
