    FILIPPELLI V. SAINT MARY’S HOSPITAL—DISSENT
    EVELEIGH, J., with whom McDONALD and VERTE-
    FEUILLE, Js., join, dissenting. I respectfully dissent
    from the majority opinion. First, unlike the majority’s
    conclusion that the testimony at issue was ‘‘collateral,’’
    I would adhere to our long-standing jurisprudence that
    ‘‘evidence tending to show a witness’ bias, prejudice or
    interest is never collateral . . . .’’ (Citation omitted.)
    Conn. Code Evid. § 6-5, commentary; see also State v.
    Chance, 
    236 Conn. 31
    , 58, 
    671 A.2d 323
     (1996). In my
    view, the evidence did relate to a substantial issue in
    the present case—namely, the credibility of Andrew
    Bazos, the only expert witness presented by the defen-
    dants Dennis M. Rodin and Waterbury Orthopaedic
    Associates, P.C.1 Second, unlike the majority, I would
    conclude that instead of weighing the ‘‘competing inter-
    ests,’’ the trial court not only unnecessarily restricted
    the ability of the plaintiff Philip Filippelli III2 to cross-
    examine Bazos, but also provided a solution that was
    without meaning and which was potentially confusing
    to the jury. Thus, in my view, the plaintiff’s right to
    cross-examine Bazos regarding motive, interest, bias
    and prejudice was unduly restricted. See Vazquez v.
    Rocco, 
    267 Conn. 59
    , 66, 
    836 A.2d 1158
     (2003).
    The present appeal arises from a medical malpractice
    action. In my view, the dispositive issue in this appeal is
    whether the trial court properly precluded the plaintiff
    from cross-examining Bazos with allegedly misleading
    and inconsistent deposition testimony.3 The trial court
    precluded the plaintiff’s cross-examination on the
    ground that the deposition testimony at issue was more
    prejudicial than probative. The trial court reached this
    conclusion because the proffered evidence revealed
    that Rodin was a defendant in two other medical mal-
    practice cases. After a jury trial, the trial court rendered
    judgment in favor of the defendants. The plaintiff then
    appealed to the Appellate Court, which affirmed the
    trial court’s judgment. Filippelli v. Saint Mary’s Hospi-
    tal, 
    141 Conn. App. 594
    , 597–600, 
    61 A.3d 1198
     (2013).
    This certified appeal followed. Filippelli v. Saint
    Mary’s Hospital, 
    308 Conn. 947
    , 
    67 A.3d 289
     (2013).
    I recognize that a trial court has broad discretion in
    ruling on the admissibility of evidence and that we will
    not disturb such a decision in the absence of an abuse
    of discretion. See, e.g., Statewide Grievance Committee
    v. Burton, 
    299 Conn. 405
    , 415, 
    10 A.3d 507
     (2011). ‘‘Nev-
    ertheless, [t]he exercise of discretion to omit evidence
    in a civil case should be viewed more critically than the
    exercise of discretion to include evidence. It is usually
    possible through instructions or admonitions to the jury
    to cure any damage due to inclusion of evidence,
    whereas it is impossible to cure any damage due to
    the exclusion of evidence.’’ (Internal quotation marks
    omitted.) Hayes v. Manchester Memorial Hospital, 
    38 Conn. App. 471
    , 474, 
    661 A.2d 123
    , cert. denied, 
    235 Conn. 922
    , 
    666 A.2d 1185
     (1995). It is through the lens
    of a more critical analysis that I would conclude that
    the trial court’s decision improperly limited the cross-
    examination of the defendants’ single expert witness
    harmed the plaintiff. Accordingly, I would reverse the
    judgment of the Appellate Court and remand the case
    for a new trial.4
    The Appellate Court opinion sets forth the following
    procedural history regarding the plaintiff’s claim.5
    ‘‘Bazos was deposed by the plaintiff’s counsel on April
    4, 2011, approximately one month prior to the start of
    trial. He testified, in part, that he had been disclosed
    as an expert witness in three or four unrelated medical
    malpractice actions, but that he could recall the name
    of only one of those cases, an action that did not involve
    Rodin. Bazos also testified that he did not know Rodin.
    When the plaintiff’s counsel asked Bazos if he had heard
    of Rodin previously, Bazos testified that he may have
    seen Rodin’s name on medical records that came across
    his desk in the course of his medical practice, as Rodin
    practices in a community near to the one in which
    Bazos practices.
    ‘‘On May 6, 2011, the court held a hearing on numer-
    ous motions in limine filed by the parties. One of the
    defendants’ motions in limine sought to preclude the
    plaintiff from presenting evidence of other medical mal-
    practice actions in which Rodin was a defendant,
    arguing that such evidence is irrelevant to the question
    of whether Rodin had breached the standard of care
    in his care and treatment of the plaintiff and was more
    prejudicial than probative. The defendants’ motion in
    limine cited the relevancy section of our [C]ode of [E]vi-
    dence. See Conn. Code Evid. § 4-1 et seq.
    ‘‘In opposing the defendants’ motion in limine, the
    plaintiff’s counsel stated that she did not intend to ques-
    tion Rodin about prior or pending medical malpractice
    actions against him, but that she planned to question
    Bazos about the number of times he had given expert
    testimony on Rodin’s behalf. She also stated that Bazos
    had been deposed in another action involving Rodin
    approximately one month prior to his being deposed
    in [the present] case, but Bazos was unable to recall
    that fact when the plaintiff deposed him. According to
    the plaintiff’s counsel, Bazos’ deposition testimony in
    this case was untruthful. . . . The plaintiff intended to
    use the deposition transcript to impeach Bazos’ credibil-
    ity and to demonstrate his bias.
    ‘‘Counsel for the defendants argued that, when testi-
    fying at the subject deposition, Bazos had misunder-
    stood the question from the plaintiff’s counsel, believing
    that she was asking him about testimony given at trial,
    not at a deposition. Counsel for the defendants stated
    that Bazos was truthful in that he had never met Rodin
    and that his relationship is with her and her firm, not
    Rodin. Moreover, Bazos intended to use an errata sheet
    to amend his deposition testimony in this case to indi-
    cate the number of times he had given testimony on
    behalf of Rodin. Counsel for the defendants argued that
    evidence of the number of times Bazos served as an
    expert witness for Rodin was a backdoor way of getting
    the number of malpractice actions against Rodin before
    the jury, regardless of the merits of those actions.
    ‘‘The court agreed that evidence regarding other med-
    ical malpractice claims against Rodin was more prejudi-
    cial than probative, but stated that the plaintiff was
    entitled to inquire whether Bazos was ‘looking at . . .
    Rodin for the first time.’ The court therefore granted
    the defendants’ motion in limine in part, but denied it
    in part to permit the plaintiff’s counsel to inquire of
    Bazos as to any prior working relationship he had
    with Rodin.
    ‘‘At trial, prior to cross-examining Bazos, the plain-
    tiff’s counsel requested a sidebar conference. There-
    after, the court excused the jury and asked Bazos to
    step outside the courtroom. [The] [p]laintiff’s counsel
    stated her desire to question Bazos about other deposi-
    tion testimony he had given on behalf of Rodin. She
    stated that, during his deposition in this case, Bazos
    testified that he did not know Rodin but that he may
    have seen his name in medical records. Moreover, Bazos
    could recall the name of only one case in which he had
    testified as an expert. [The] [p]laintiff’s counsel stated
    that Bazos gave a deposition on Rodin’s behalf in the
    case of George v. Rodin, Superior Court, judicial district
    of Waterbury, Docket No. CV-09-5014966-S, approxi-
    mately two months prior to the day he was deposed in
    this action. Five days prior to the deposition in this
    case, Bazos signed the deposition errata sheet in George
    . . . but testified that he could not recall the names of
    any other cases in which he had testified. [The] [p]lain-
    tiff’s counsel argued that Bazos’ deposition testimony,
    therefore, was not truthful.
    ‘‘The court pointed out that, if it were to permit the
    plaintiff to question Bazos about George . . . in front
    of the jury and Bazos admitted that he is an expert in
    that case, evidence of another medical malpractice
    claim against Rodin would be before the jury. [The]
    [p]laintiff’s counsel argued that Bazos denied, under
    oath, knowing the names of the cases in which he had
    been disclosed as an expert witness and that such evi-
    dence was necessary for the jury to determine Bazos’
    credibility, which went to the heart of his veracity and
    whether he was truthful.
    ‘‘The court denied the plaintiff’s request to make an
    offer of proof, ruling that the plaintiff could ask Bazos
    whether he had a working relationship with Rodin and
    that he could challenge Bazos’ credibility, but not with
    evidence of other medical malpractice claims against
    Rodin, as its prejudicial value far outweighs its proba-
    tive value.
    ‘‘At the end of the court day, after Bazos had com-
    pleted his testimony and the jury had been excused,
    the plaintiff sought to mark a document for identifica-
    tion. The court declined the plaintiff’s request, but per-
    mitted counsel to make an oral record.6 Plaintiff’s
    counsel identified the document as ‘the witness certifi-
    cation for [a] deposition that was taken on January 21,
    2011. The certification was witnessed on March 29,
    2011, by . . . Bazos in . . . George . . . .’ ’’ (Citation

    Although I agree generally with the standard of
    review set forth in the majority opinion, I set forth
    our well established standard of review to frame my
    analysis of the plaintiff’s claim. ‘‘The standard under
    which we review evidentiary claims depends on the
    specific nature of the claim presented. . . . To the
    extent a trial court’s admission of evidence is based on
    an interpretation of [law], our standard of review is
    plenary. . . . We review the trial court’s decision to
    admit evidence, if premised on a correct view of the
    law, however, for an abuse of discretion.’’ (Citations

    ‘‘Nevertheless, ‘[t]he exercise of discretion to omit
    evidence in a civil case should be viewed more critically
    than the exercise of discretion to include evidence. It

    Hospital, supra,

    .
    In the present case, Bazos testified at his deposition
    that he had testified as an expert in three or four other
    medical malpractice cases over a period of six years
    prior to his deposition. When asked whether he knew
    the names of any of the physicians for whom he had
    been disclosed as a witness and given testimony, Bazos
    testified ‘‘[t]he only one I remember, because it was
    relatively recent, was [a physician named] Geiger
    . . . .’’
    When asked if he knew any of the physicians that
    subsequently treated the plaintiff, Bazos testified that
    he did not know them personally and had not worked
    with any of them. When asked if he had ever heard of
    Rodin before being involved in this case, Bazos testified
    that ‘‘I’ve seen his name; I’ve not worked with him, but
    Waterbury is not that far away, and we’ll occasionally
    see patients that live there and may have been treated
    out there in the past.’’7 During his entire deposition,
    Bazos never mentioned that he had been retained by
    the defendants’ counsel as an expert witness in other
    medical malpractice cases in which Rodin was named
    as a defendant.
    Contrary to his testimony at his deposition, a review
    of the record indicates that of the four medical malprac-
    tice cases for which Bazos had been retained and given
    testimony, he testified on behalf of Rodin in three of
    them. In each of those matters, Bazos had also been
    retained by the defendants’ counsel. Bazos had given
    a deposition approximately two months before his
    deposition in this case in another case involving Rodin.
    Indeed, while meeting with the defendants’ counsel to
    prepare for his deposition in the present case, Bazos
    signed an errata sheet for his deposition in that other
    case involving Rodin.
    On the basis of the foregoing, the plaintiff asserts
    that Bazos lied under oath at his deposition and that the
    trial court improperly precluded him from impeaching
    Bazos at trial with the allegedly untruthful testimony
    from his deposition. The defendants respond that
    Bazos’ testimony was not misleading and that, even if
    it was, it was proper for the trial court to exclude it
    because it was more prejudicial than probative. I agree
    with the plaintiff and would conclude that evidence
    regarding Bazos’ misleading testimony at his deposition
    was admissible as both evidence of bias and a specific
    incident of misconduct relating to veracity.
    The majority concludes that ‘‘whether Bazos pre-
    viously served as an expert on behalf of Rodin was a
    collateral matter because it was relevant only to Bazos’
    credibility and not to any substantive issue in the case.’’
    I disagree. It is well established that ‘‘evidence tending
    to show a witness’ bias, prejudice or interest is never
    collateral . . . .’’ (Citation omitted.) Conn. Code Evid.

    pal means by which the credibility of witnesses and the
    truth of their testimony is tested.’ State v. Lee,

    , 69, 
    640 A.2d 553
     (1994). Although only relevant evi-

    dence tending to show motive, bias or interest of an

    State v. Chance, supra, 
    236 Conn. 58
    . As this court
    explained in Vasquez v. Rocco, supra, 
    267 Conn. 66
    –67,
    ‘‘the risk of undue prejudice to the defendant resulting
    from the introduction of such evidence must be weighed
    against the plaintiff’s right of cross-examination regard-
    ing motive, interest, bias or prejudice, a right that may
    not be unduly restricted. E.g., Pet v. Dept. of Health
    Services,

    , 663,

     (1994); see also
    General Statutes § 52-145 (b) (‘[a] person’s interest in
    the outcome of the action . . . may be shown for the
    purpose of affecting his credibility’); Conn. Code Evid.
    § 6-5 (‘[t]he credibility of a witness may be impeached
    by evidence showing bias for, prejudice against, or inter-
    est in any person or matter that might cause the witness
    to testify falsely’). Furthermore, ‘[a] basic and proper
    purpose of cross-examination of an expert is to test
    that expert’s credibility.’ . . . State v. Copas, [
    252 Conn. 318
    , 327, 
    746 A.2d 761

    ‘‘ ‘The bias of a witness, like prejudice and relation-
    ship, is not a collateral matter. The bias of a witness
    is always a relevant subject of inquiry when confined
    to ascertaining [a] previous relationship, feeling and
    conduct of the witness . . . . [O]n cross-examination
    great latitude is allowed and . . . the general rule is
    that anything tending to show the bias on the part of a
    witness may be drawn out.’ [Henson v. Commonwealth,

    , 825–26,

     (1936); see also] Nor-
    folk & Western Railway Co. v. Birchfield, 
    105 Va. 809
    ,
    812, [
    54 S.E. 879
    ] (1906) (repeating the general rule but
    concluding under the circumstances of that case that
    it was harmless error not to permit a particular question
    because the information sought by the questioner was
    developed by other evidence).’’ (Emphasis omitted.)

    235 Va. 181
    , 188, 
    366 S.E.2d 109
    (1988).
    In the present case, the fact that Bazos had been
    retained by the defendants’ counsel in two other matters
    on behalf of Rodin was relevant to the issue of his
    potential bias or interest in the outcome of the case.
    In Vasquez v. Rocco, supra, 
    267 Conn. 65
    , this court
    addressed a similar issue. In Vasquez, the plaintiff
    sought to cross-examine the defendant’s expert regard-
    ing his connection to the defendant’s liability insurance
    carrier. 
    Id., 64
    . The trial court precluded the plaintiff
    from cross-examining the defendant’s expert on the
    ground that the probative value of the evidence would
    be outweighed by its prejudicial effect. 
    Id.,
     64–65. This
    court concluded that the trial court improperly pre-
    cluded the plaintiff from cross-examining the expert
    because the expert’s connection to the insurance carrier
    ‘‘was substantial enough to warrant the admission of
    evidence of that connection for the purpose of demon-
    strating [the expert’s] potential interest in the outcome
    of the case.’’ 
    Id., 69
    . Indeed, this court has recognized
    that ‘‘ ‘[i]t is usually held that it is permissible for plain-
    tiff’s counsel, when acting in good faith, to show the
    relationship between a witness and [the] defendant’s
    insurance company where such evidence tends to show
    the interest or bias of the witness and affects the weight
    to be accorded his testimony.’ Annot., 
    4 A.L.R.2d 761
    ,
    [§ 7 (1949)].’’ Magnon v. Glickman, 
    185 Conn. 234
    , 242,
    
    440 A.2d 909
     (1981).
    This view is consistent with the approach of other
    jurisdictions that allow cross-examination of medical
    experts as to specific prior referrals from attorneys
    involved in the present case and testimony on behalf
    of clients of the attorney. Indeed, the Supreme Court
    of Illinois has explained the rationale for allowing such
    cross-examination as follows: ‘‘The modern personal
    injury trial often becomes a battle between expert wit-
    nesses. This is particularly true in a case [in which the
    cause of the] injury is beyond the knowledge of the
    average person, and a jury must ordinarily rely on the
    testimony of experts in reaching a verdict. . . . An
    expert medical witness is an important part of the tech-
    nique of personal injury litigation. He generally is a
    persuasive, fluent, impressive witness, able to make
    the jury understand that what he is telling them is the
    product of years of educational preparation and medical
    experience, with particular reference to and emphasis
    on the specialty involved. He will name his colleges
    and universities, his degrees, the medical societies to
    which he belongs, the national specialty groups to
    which he has been admitted, the hospitals in which he
    has interned or externed, and the hospital staffs on
    which he has held positions. . . . That he is being paid
    by one side is always skillfully lost in casual answers
    to cross-examining cynical questions, by a modest shrug
    indicating that a charge is made per hour or day, which
    seems wholly inconsequent to the large proportions
    from which his great capacities emerge.’’ (Internal quo-
    tation marks omitted.) Sears v. Rutishauser, 
    102 Ill. 2d 402
    , 406, 
    466 N.E.2d 210
     (1984). Accordingly, the
    Supreme Court of Illinois explained that ‘‘[i]t is compe-
    tent to show that a witness . . . is in the employ of
    one of the litigants regularly or frequently as an expert
    witness, or to prove facts and circumstances which
    would naturally create a bias in the mind of the witness
    for or against the cause of either of the litigants.’’ (Inter-
    nal quotation marks omitted.)

    expert can be questioned about fee arrangements, prior
    testimony for the same party, and financial interest in
    the outcome of the case.’’

    .
    In Sawyer v. Comerci, 
    264 Va. 68
    , 77–80, 
    563 S.E.2d 748
     (2002), the Supreme Court of Virginia addressed a
    very similar issue to the present case—whether a trial
    court properly precluded the plaintiff in a medical mal-
    practice action from cross-examining the defendant’s
    expert to show that he had previously testified on behalf
    of the defendant and had been compensated for his
    testimony. The Supreme Court of Virginia concluded
    that the trial court abused its discretion in refusing to
    permit the plaintiff to elicit testimony from the defen-
    dant’s expert related to his testimony in an unrelated
    action. 
    Id.,
     79–80. The Supreme Court of Virginia
    explained as follows: ‘‘[I]n this case the plaintiff was
    entitled to cross-examine the defendant’s expert wit-
    ness . . . to show that he had previously testified as
    an expert witness on behalf of [the defendant] and that
    he had been compensated. The amount of money that
    [the defendant] paid [the defendant’s expert] in a prior
    case was a relevant area of inquiry because that testi-
    mony may have indicated to the jury that he was biased
    in her favor. The probative value concerning this poten-
    tial bias outweighed any prejudice to [the defendant]
    resulting from the jury’s knowledge that she had been
    a defendant in an unrelated [action]. Therefore, the
    circuit court abused its discretion in failing to permit
    the plaintiff to elicit this testimony.’’ 
    Id.
     Accordingly,
    the Supreme Court of Virginia reversed the judgment
    of the trial court and remanded the case for a new trial.
    
    Id., 80
    .
    Furthermore, the plaintiff in the present case should
    have been allowed to cross-examine Bazos regarding
    his inconsistent testimony at the deposition because
    prior inconsistent testimony was relevant to his credi-
    bility. It is axiomatic that ‘‘[a] witness may be impeached
    by specific acts of misconduct that evidence a lack of
    veracity.’’ C. Tait & E. Prescott, Connecticut Evidence
    (5th Ed. 2014) § 6.32.2, p. 397. This court has repeatedly
    concluded that ‘‘[t]o attack the credibility of a witness,
    inquiry may be made, in the discretion of the trial court,
    as to particular acts of misconduct tending to show a
    lack of veracity even though such evidence may be
    irrelevant to the issues in the case.’’ State v. Sharpe,
    
    195 Conn. 651
    , 658, 
    491 A.2d 345
     (1985). ‘‘In an attack
    on his credit, inquiry may be made, in the discretion of
    the court, as to particular acts of misconduct tending

    ‘‘[a] claim that the witness gave false testimony in a
    prior case is directly relevant to a witness’ credibility.
    See, e.g., State v. Bova,

    may be asked about his or her prior acts of misconduct,
    the questioner must have a good-faith basis for believing
    that the witness has committed the act inquired about.’’

    ‘‘Cross-examination is an indispensable means of elic-
    iting facts that may raise questions about the credibility
    of witnesses and, as a substantial legal right, it may not

    examination. Richmond v. Longo, [supra, 
    27 Conn. App. 38

    witness is a matter to be determined by the trier of
    fact. In re Juvenile Appeal,

    .
    In the present case, the parties do not dispute that,
    at the time of his deposition in the present case, Bazos
    had been retained by counsel for the defendants to be an
    expert witness on behalf of Rodin in two other medical
    malpractice cases. The parties also do not dispute that
    Bazos had testified at a deposition in one of the other
    medical malpractice cases involving Rodin approxi-
    mately two months prior to his deposition in the present
    case. Further, it is undisputed that on the day Bazos
    met with counsel for the defendants to prepare for the
    deposition in the present case, five days before the
    deposition in the present case, he signed an errata sheet
    for a deposition in another case in which Rodin was
    named as the defendant.
    At his deposition, Bazos testified that he had given
    testimony in three or four other medical malpractice
    cases. Bazos was asked the following question: ‘‘Do you
    remember the names of any of the physicians for which
    you have given deposition testimony as a disclosed
    expert on their behalf?’’ Bazos replied, ‘‘[t]he only one
    I remember, because it was relatively recent, was . . .
    Geiger . . . .’’ Indeed, when explicitly asked if he had
    ever heard of Rodin before, Bazos replied as follows:
    ‘‘I’ve seen his name; I’ve not worked with him, but
    Waterbury is not that far away, and we’ll occasionally
    see patients that live there and may have been treated
    out there in the past.’’ This testimony by Bazos implies
    that his only knowledge of Rodin was through records
    of patients that Bazos treated. Such testimony com-
    pletely omits the fact that he had reviewed records in
    other medical malpractice cases in which Rodin was
    named as a defendant and that Bazos was hired as an
    expert in those cases. Given the fact that it is undisputed
    that Bazos gave deposition testimony in a case where
    Rodin was the named defendant approximately two
    months prior to his deposition in the present case, and
    the fact that the deposition in the case involving Geiger
    was approximately one year before, I conclude that the
    plaintiff had a good faith belief that Bazos had lied
    under oath.8
    The majority states that the trial court ‘‘also recog-
    nized . . . that the plaintiff had a legitimate interest in
    impeaching Bazos’ credibility by questioning him about
    his allegedly false or misleading deposition testimony.
    The court sought to balance these concerns by allowing
    the plaintiff to confront Bazos with the portion of his
    deposition testimony in which he stated that he was
    only familiar with Rodin’s name because he had seen
    it in his patients’ medical records and ask whether
    Bazos had a ‘working relationship’ with Rodin, but pre-
    cluded the plaintiff from inquiring more specifically
    about other malpractice cases against Rodin.’’ I dis-
    agree. By limiting the plaintiff to being able to ask only
    about a ‘‘prior working relationship’’ with Rodin, it did
    not enable the plaintiff to elicit the fact that Bazos had
    not been forthcoming about his relationship with Rodin.
    The vague notion of ‘‘prior working relationship’’ did
    not convey the extent to which the testimony Bazos
    gave at his deposition may have been misleading and
    not forthright. Specifically, the trial court precluded the
    plaintiff from questioning Bazos regarding whether he
    had falsely testified during his deposition. Specifically,
    the trial court allowed the plaintiff to inquire into
    whether Bazos had a ‘‘working relationship’’ with
    Rodin, but precluded the plaintiff from introducing evi-
    dence that Bazos had omitted from his deposition testi-
    mony that he had been disclosed as an expert and
    testified on behalf of Rodin in other cases. The trial
    court precluded the plaintiff from introducing evidence
    that Bazos may have lied at his deposition about being
    disclosed as an expert in two other actions involving
    Rodin on the ground that information regarding the
    other medical malpractice actions involving Rodin
    would have been more prejudicial than probative. The
    exact nature of this ‘‘prior working relationship’’ was
    never explained to the jury and was potentially a source
    of confusion. What exactly does it mean? Were they
    partners? Did one work for the other and refer patients?
    Did they share one mutual patient at a given time?
    Were they residents in the same hospital? The fact was
    potentially very confusing to the jury and of limited
    evidentiary value. It certainly cannot compare to the
    potential of suggesting to the jury that Bazos may have
    lied under oath and may have had a bias and interest
    to testify in favor of Rodin.
    At trial, the plaintiff was allowed to question Bazos
    about whether he had an ongoing working relationship
    with Rodin. Bazos testified that he had an indirect ongo-
    ing relationship with Rodin, but that he met him for
    the first time the previous day.9 By being limited to
    questioning Bazos only about their ‘‘working relation-
    ship,’’ the plaintiff was never able to introduce evidence
    that, at his deposition, Bazos had omitted any reference
    to testifying on behalf of Rodin at other depositions or
    being named as an expert on Rodin’s behalf in other
    matters.
    Indeed, once Bazos testified at trial that he had ‘‘an
    indirect working relationship with Rodin,’’ Bazos’ depo-
    sition testimony became a potential inconsistent state-
    ment under oath. It is well established that ‘‘[a] witness
    can be impeached by proof that he or she has made
    prior statements, either out-of-court or in a former pro-
    ceeding, that are inconsistent with the [witness’] in-
    court testimony.’’ C. Tait & E. Prescott, supra, § 6.35.2,
    p. 417. ‘‘Inconsistencies may be shown not only by con-
    tradictory statements but also by omissions, in other
    words, failures to mention certain facts. Thus, if the
    prior statement fails to mention a material fact presently
    testified to that it should have been natural to mention
    in the prior statement, the prior statement is sufficiently
    inconsistent. State v. Reed, [
    174 Conn. 287
    , 302–303, 
    386 A.2d 243
     (1978)].’’ (Internal quotation marks omitted.)

     (1997); 
    id.
     (concluding it was improper
    for trial court to exclude witness’ prior inconsistent
    statement for impeachment purposes).
    In the present case, Bazos’ omission in his deposition
    testimony that he had testified on behalf of Rodin when
    that testimony occurred approximately two months
    prior to his deposition and he signed an errata sheet
    approximately five days before the deposition in a case
    in which Rodin was the named defendant was relevant
    to his veracity and possible inconsistency. I recognize
    that, ‘‘even if the conduct does relate to veracity, the
    court still has discretion to exclude it if the evidence
    has slight relevance due to remoteness in time or other
    considerations . . . or if it has a tendency to confuse
    or impede the litigation by interjecting collateral issues
    . . . .’’ (Citations omitted.) C. Tait & E. Prescott, supra,
    § 6.32.4, pp. 399–400. Nevertheless, in the present case,
    Bazos’ conduct at his deposition was not remote in
    time—it occurred one month before trial. Moreover,
    although the trial court was worried about the prejudi-
    cial effect of evidence regarding the other medical mal-
    practice actions, I would conclude that any prejudicial
    effect could have been resolved by a limiting instruction
    to the jury as to its use of the evidence and a further
    appropriate limitation that allowed the plaintiff to intro-
    duce only evidence that Bazos had not revealed that
    he testified on behalf of Rodin approximately one
    month prior to his deposition and had been retained in
    other actions without getting into the merits of those
    other actions. ‘‘Evidence may be admitted for impeach-
    ment purposes even though it is inadmissible as sub-
    stantive evidence on the merits of the case. See [Conn.
    Code Evid.] § 1-4 . . . . In admitting such evidence,
    the jury should be instructed as to the proper and lim-
    ited purpose for which it was received. . . . That the
    evidence might be misused by the jury in violation of
    the court’s instructions is not grounds for excluding
    it.’’ (Citations omitted.) C. Tait & E. Prescott, supra,
    § 6.27.6, pp. 385–86.
    As the Supreme Court of Illinois explained: ‘‘The prin-
    cipal safeguard against errant expert testimony is cross-
    examination. Generally, opposing counsel may probe
    bias, partisanship or financial interest of an expert wit-
    ness on cross-examination. . . . It is competent to
    show that a witness . . . is in the employ of one of
    the litigants regularly or frequently as an expert witness,
    or to prove facts and circumstances which would natu-
    rally create a bias in the mind of the witness for or
    against the cause of either of the litigants.’’ (Citation
    omitted; internal quotation marks omitted.) Sears v.
    Rutishauser, 
    supra,
     
    102 Ill. 2d 407
    . In the present case,
    the plaintiff was not given the opportunity to employ
    this important safeguard.
    Accordingly, I would conclude that the trial court
    abused its discretion by precluding the plaintiff from
    inquiring into, and introducing evidence relevant to,
    whether Bazos had given misleading and inconsistent
    testimony at his deposition about his relationship with
    Rodin, and by limiting the plaintiff to only inquiring into
    the ‘‘working relationship’’ between Bazos and Rodin.
    Having concluded that the trial court abused its dis-
    cretion, I must now determine whether the evidentiary
    impropriety was harmless. ‘‘[A]n evidentiary ruling will
    result in a new trial only if the ruling was both wrong and
    harmful. . . . Moreover, an evidentiary impropriety in
    a civil case is harmless only if we have a fair assurance
    that it did not affect the jury’s verdict.’’ (Citations omit-

    includes a review of: (1) the relationship of the improper

    as highlighted by the parties’ summations; (2) whether
    the trial court took any measures, such as corrective

     (2014).
    In the present case, an evaluation of these factors
    demonstrates that the trial court’s improper exclusion
    of evidence bearing on Bazos’ credibility was harmful.
    First, Bazos’ credibility was essential to the case. Bazos
    was the only expert who testified for the defendants.
    His testimony was essential to the key issue in the
    case—namely, whether the defendants had breached
    the standard of care. Bazos’ testimony contradicted the
    testimony of the plaintiff’s only expert, Ronald Kras-
    nick. Therefore, the jury was left to determine which
    of the two experts it believed—a battle of the experts.
    It is well established that ‘‘[t]he success of much
    litigation—both criminal and civil—is dependent upon
    the effectiveness of a litigant’s expert witness. Gener-
    ally, the cross-examination of an expert allows for wide-
    ranging questioning which touches on all matters testi-
    fied to in chief, or which tends to test the qualifications,
    skill, or knowledge of the witness and the accuracy or
    value of his or her opinion.’’ Annot., 
    11 A.L.R.5th 1
    (1993). Indeed, this court has repeatedly stated that
    ‘‘[w]hen experts’ opinions conflict, as often happens in
    medical malpractice cases, ‘[i]t is the province of the
    jury to weigh the evidence and determine the credibility
    and the effect of testimony . . . . [T]he jury is free to
    accept or reject each expert’s opinion in whole or in
    part.’ ’’ Grondin v. Curi, 
    262 Conn. 637
    , 657 n.20, 
    817 A.2d 61
     (2003). In the present case, the experts’ opinions
    did conflict and the jury was left to determine which
    expert it believed. In such a case, the credibility of the
    defendants’ expert was essential to the jury’s ultimate
    resolution of the case—it had to decide whether to
    accept or reject his opinion. Therefore, Bazos’ credibil-
    ity was central to this case.
    Second, the trial court did not attempt to cure any
    possible prejudice caused by the improper exclusion
    of the testimony. To the contrary, as explained pre-
    viously in this opinion, although the trial court allowed
    the plaintiff to inquire into Bazos’ working relationship
    with Rodin, such inquiry was not sufficient and did not
    allow the plaintiff to impeach the credibility of Bazos.
    Furthermore, the trial court could have cured any possi-
    ble prejudice to the defendants created by the introduc-
    tion of evidence that Bazos was involved in other
    litigation on behalf of Rodin by instructing the jury
    regarding the limited purpose of impeachment evidence
    and not allowing any inquiry into the details of those
    other cases.
    Third, the particular evidence of the allegedly mis-
    leading and inconsistent testimony by Bazos was not
    cumulative of any other evidence at trial. Indeed, the
    defendants were allowed to introduce Bazos as an
    expert, discuss his qualifications and offer his testimony
    as an expert. The plaintiff was not allowed to impeach
    his credibility and show that Bazos may have offered
    misleading and inconsistent testimony during the
    course of the litigation.
    My review of the entire record in the present case,
    in light of these considerations, compels the conclusion
    that there is no fair assurance that the evidentiary
    impropriety did not affect the jury’s verdict because
    the improperly excluded testimony was essential to
    weighing the testimony of the defendants’ only expert
    witness who was testifying regarding the central issue
    in this case—whether the defendants breached the stan-
    dard of care. Moreover, the exclusion of this evidence
    was not wholly cumulative of other testimony or evi-
    dence. Accordingly, I would conclude that the trial
    court’s decision to preclude the plaintiff from cross-
    examining Bazos with regard to his potentially mis-
    leading and inconsistent testimony harmed the plaintiff
    and that, therefore, the plaintiff is entitled to a new trial.
    1
    As noted by the majority, all claims against Saint Mary’s Hospital were
    withdrawn before trial. See footnote 2 of the majority opinion. For the sake
    of simplicity, I refer to Rodin and Waterbury Orthopaedic Associates, P.C.,
    collectively as the defendants. Where necessary, I refer to these parties
    individually by name.
    2
    I also note that, although Linda Filippelli was originally a plaintiff in the
    underlying action, she withdrew her claims prior to trial. See footnote 1 of
    the majority opinion. For the sake of simplicity, all references to the plaintiff
    in this opinion are to Philip Filippelli III.
    3
    The plaintiff also claims that the trial court improperly refused to allow
    him to make an offer of proof regarding Bazos’ misleading and inconsistent
    testimony. I note that a trial court always should allow a party to make an
    offer of proof in order to preserve a claim for appellate review. I do not
    reach the plaintiff’s claim regarding the offer of proof, however, because I
    would conclude that the trial court improperly precluded the plaintiff from
    offering evidence regarding Bazos’ allegedly misleading and inconsistent
    testimony and remand the matter for a new trial.
    4
    Because I would remand the case for a new trial, I do not address the
    other evidentiary claims relating to the use of the academic journal article,
    which the plaintiff raised on appeal.
    5
    I agree with the facts and procedural history as set forth in the majority
    opinion and, therefore, include only those additional facts that are relevant
    to my analysis.
    6
    I note that a trial judge should always allow counsel to mark a document
    for identification purposes in order to preserve any appellate claims with
    an appropriate record.
    7
    Specifically, the following colloquy between the plaintiff’s counsel and
    Bazos occurred during Bazos’ deposition:
    ‘‘Q. . . . How many medical malpractice cases would you say you’ve
    given testimony in?
    ‘‘A. Maybe three or four.
    ‘‘Q. Over what period of time?
    ‘‘A. Probably the past six years.
    ‘‘Q. Do you know the names of any of the parties that you have given
    deposition testimony on behalf of? In other words, I take it you were dis-
    closed as an expert on behalf of a physician, correct?
    ‘‘A. Yes.
    ‘‘Q. Do you remember the names of any of the physicians for which you
    have given deposition testimony as a disclosed expert on their behalf?
    ‘‘A. The only one I remember, because it was relatively recent, was . . .
    Geiger . . . .
    ***
    ‘‘Q. The other two, maybe three cases in which you have given deposition
    testimony as an expert; who have you worked with on those cases? What
    firm; do you know?
    ‘‘A. I believe with [counsel for the defendants] . . . .
    ***
    ‘‘Q. Do you know . . . Rodin?
    ‘‘A. No.
    ***
    ‘‘Q. Had you ever heard of . . . Rodin before being involved in this case?
    You said you hadn’t worked with him before.
    ‘‘A. I’ve seen his name; I’ve not worked with him, but Waterbury is not
    that far away, and we’ll occasionally see patients that live there and may
    have been treated out there in the past.’’
    8
    The defendants assert that the alleged false testimony was ‘‘clarified in
    his errata sheet.’’ The errata sheet referred to by the defendants was com-
    pleted on May 9, 2011, approximately three days after the trial court heard
    argument on the motions in limine in this matter and determined that the
    plaintiff would not be allowed to introduce any evidence of other medical
    malpractice actions in which Rodin was named as a defendant. In his errata
    sheet, Bazos testified: ‘‘I have never met . . . Rodin but [the defendants’
    counsel] retained me as an expert witness in two other cases for . . .
    Rodin.’’ The existence of the errata sheet, however, did not preclude the
    plaintiff’s right to cross-examine Bazos. The defendants would have been
    free to offer the errata sheet during his direct examination of Bazos and
    explore it during his redirect testimony.

    At trial, the following colloquy occurred:
    ‘‘[The Plaintiff’s Counsel]: And it’s true . . . isn’t it, that you’ve had an
    ongoing working relationship with . . . Rodin since about 2008 . . . ?
    ‘‘[Bazos]: Yes.
    ‘‘[The Plaintiff’s Counsel]: And, in fact, you’ve been working with him on
    several independent matters since that time, correct?
    ‘‘[Bazos]: No, I’ve not worked with him, I’ve worked . . . indirectly with
    him through another person.
    ‘‘[The Plaintiff’s Counsel]: So you have not had a working relationship
    with him—
    ‘‘[Bazos]: On—
    ‘‘[The Plaintiff’s Counsel]: —since 2008?
    ‘‘[Bazos]: I have. It depends how you define working relationship?
    ‘‘[The Plaintiff’s Counsel]: And that—one—actually, one of those relation-
    ships continues, presently; isn’t that right?
    ‘‘[Bazos]: Yes.
    ‘‘[The Plaintiff’s Counsel]: So at least since 2008 you’ve had had a working
    relationship with him, correct?
    ‘‘[Bazos]: Yes.
    ‘‘[The Plaintiff’s Counsel]: Now, do you remember being asked at your
    deposition, which was taken just about a month ago on April 4, 2011, as to
    whether you’ve ever heard of . . . Rodin?
    ‘‘[Bazos]: I’d have to see the—how you asked it. I think you asked me if
    I knew him.
    ‘‘[The Plaintiff’s Counsel]: Okay. Did you recall testifying that you had
    not worked with him?
    ‘‘[Bazos]: I’d have to see it. I don’t have an independent recall, no.
    ‘‘[The Plaintiff’s Counsel]: You don’t have an independent recall?
    ‘‘[The Plaintiff’s Counsel]: No. . . .
    ‘‘[The Plaintiff’s Counsel]: Can I have the . . . deposition transcript.
    Exhibit 23 for [identification], Your Honor.
    ‘‘The Court: Thank you.
    ‘‘[Bazos]: Thank you.
    ‘‘[The Plaintiff’s Counsel]: I’m going to direct your attention to page 142,
    line 20.
    ‘‘[Bazos]: I have it.
    ‘‘[The Plaintiff’s Counsel]: The question was, had you ever heard of . . .
    Rodin before being involved in this case? You said, you hadn’t worked with
    him before. And what was your answer?
    ‘‘[Bazos]: I’m reading from my deposition. I’ve seen his name, I’ve not
    worked with him, but Waterbury is not that far away and will occasionally
    see patients that live there and may have been treated out there in the past.
    4, 2011, just a little over a month ago, correct . . .?
    ‘‘[Bazos]: That’s correct, yes.
    ‘‘[The Plaintiff’s Counsel]: And you had seen his name before that deposi-
    tion, correct?
    ‘‘[Bazos]: That’s what I said. I said—I just read—I’ll read it again. I said,
    I’ve seen his name.
    ‘‘[The Plaintiff’s Counsel]: Right. You had a working relationship that
    dated back to 2008 and this deposition was given on April 4, 2011; isn’t
    that right?
    ‘‘[Bazos]: I met . . . Rodin yesterday for the first time in my life.
    ‘‘[The Plaintiff’s Counsel]: So your testimony [is that] you did not have a
    working relationship with him or that you did?
    ‘‘[Bazos]: I just said earlier that I did have a working relationship. I met
    him yesterday for the first time.
    ‘‘[The Plaintiff’s Counsel]: And according to the answer that you gave at
    your deposition you made it appear as though you may have come across
    his name by—in one of your patient’s records; isn’t that the gist of your tes-
    timony?
    ‘‘[Bazos]: No. Apparently, that’s your interpretation. Maybe I should just
    read it again. I said, I’ve seen—
    ‘‘[The Plaintiff’s Counsel]: Yes, why don’t you read it again.
    ‘‘[Bazos]: I’ve seen his name, I’ve not worked with him, but Waterbury is
    not that far away and will occasionally see patients that live there and may
    have been treated out there in the past.
    ‘‘[The Plaintiff’s Counsel]: So you have a working relationship with him
    that began in 2008, but you have not worked with him; is that your testimony?
    ‘‘[Bazos]: Yeah. I met him yesterday for the first time.
    ‘‘[The Plaintiff’s Counsel]: Okay. But you’ve had a working relationship
    with him that dates back to 2008—
    ‘‘[The Defendants’ Counsel]: Objection, Your Honor. Asked and answered.
    ‘‘[The Plaintiff’s Counsel]: —isn’t that right . . . ?
    ‘‘[The Defendants’ Counsel]: —like, four or five times now. Can we have
    a sidebar, please?
    ‘‘The Court: Yes.’’
