    STATE v. SIMMONS—CONCURRENCE
    BEAR, J., concurring in part and concurring in the
    judgment. The defendant, Kevan Simmons, appeals
    from the judgment of conviction, rendered following a
    jury trial, of two counts of assault in the first degree
    in violation of General Statutes § 53a-59 (a) (5), and
    one count each of criminal possession of a pistol or
    revolver in violation of General Statutes § 53a-217c (a)
    (1) and carrying a pistol without a permit in violation
    of General Statutes § 29-35 (a). On appeal, the defendant
    claims that (1) the prosecutor violated his constitutional
    rights to due process and a fair trial by committing
    improprieties during closing argument; (2) his due pro-
    cess rights were violated when the state failed to dis-
    close a police internal affairs report detailing the
    misconduct of a police detective who was a primary
    witness for the state; and (3) the state improperly
    entered into an agreement to immunize testimony from
    George Harris, a victim of the shooting and a key wit-
    ness, including any lies and falsehoods that would con-
    stitute the crime of perjury, and that agreement
    constituted plain error that was either structural error
    or otherwise not subject to a harmless error analysis;
    and (4) the improper agreement to immunize Harris’
    testimony, which the state anticipated would include
    Harris’ perjury in denying knowledge, inter alia, about
    who shot him, warrants the exercise of this court’s
    supervisory authority to reverse the defendant’s convic-
    tion and award him a new trial.1
    I agree with the majority that the state’s illegal and
    improper agreement with Harris to immunize all of his
    anticipated testimony, including any testimony that the
    state anticipated would constitute the crime of perjury,
    and the trial court’s knowing acceptance and implemen-
    tation of that illegal and improper agreement, warrants
    a reversal of the defendant’s conviction and a remand
    of this case for a new trial. I write separately, however,
    because I do not agree that the majority’s invocation
    of this court’s supervisory authority in its thorough,
    thoughtful, and well written opinion is necessary in this
    case. I would, instead, reverse the defendant’s convic-
    tion on the ground that the trial court’s acceptance and
    implementation of the agreement for the illegal and
    improper immunization of Harris’ anticipated testi-
    mony, including any testimony that would constitute
    the crime of perjury, constituted plain error that was
    structural error in the context of the defendant’s crimi-
    nal trial.2
    Before addressing the defendant’s claim of plain
    error, I discuss the other claims raised by the defendant
    in support of his argument that the conviction should
    be reversed to determine whether reversal is warranted
    on a basis separate from plain error review.
    I accept the facts as set forth in the majority opinion.
    Additional facts are set forth as relevant to the claims
    that are addressed in this concurring opinion.
    I
    PROSECUTORIAL IMPROPRIETY
    The defendant first claims that the prosecutor vio-
    lated his rights to due process and a fair trial when he
    committed several improprieties during closing argu-
    ment. Specifically, the defendant claims that the prose-
    cutor improperly (1) denigrated defense counsel; (2)
    asked the jury to use impeachment evidence substan-
    tively; (3) expressed his opinion about the credibility
    of two witnesses; (4) appealed to the jurors’ emotions;
    and (5) injected extraneous matters into the trial. The
    state argues that the prosecutor did not commit any
    improprieties during closing argument and that, even
    if he did, they did not deprive the defendant of his rights
    to due process and a fair trial.
    Although the defendant did not object to the pur-
    ported improprieties he now challenges on appeal,
    ‘‘under settled law, a defendant who fails to preserve
    claims of prosecutorial [impropriety] need not seek to
    prevail under the specific requirements of State v. Gold-
    ing, 
    213 Conn. 233
    , 239–40, 
    567 A.2d 823
    (1989), and,
    similarly, it is unnecessary for a reviewing court to
    apply the four-pronged Golding test.’’ (Internal quota-
    tion marks omitted.) State v. Payne, 
    303 Conn. 538
    , 560,
    
    34 A.3d 370
    (2012).
    ‘‘In analyzing claims of prosecutorial impropriety, we
    engage in a two step analytical process. . . . The two
    steps are separate and distinct. . . . We first examine
    whether prosecutorial impropriety occurred. . . . Sec-
    ond, if an impropriety exists, we then examine whether
    it deprived the defendant of his due process right to
    a fair trial. . . . In other words, an impropriety is an
    impropriety, regardless of its ultimate effect on the fair-
    ness of the trial. Whether that impropriety was harmful
    and thus caused or contributed to a due process viola-
    tion involves a separate and distinct inquiry.’’ (Internal
    quotation marks omitted.) State v. Campbell, 
    328 Conn. 444
    , 541–42, 
    180 A.3d 882
    (2018).
    ‘‘As we previously have recognized, prosecutorial
    [impropriety] of a constitutional magnitude can occur
    in the course of closing arguments. . . . When making
    closing arguments to the jury, [however] [c]ounsel must
    be allowed a generous latitude in argument, as the limits
    of legitimate argument and fair comment cannot be
    determined precisely by rule and line, and something
    must be allowed for the zeal of counsel in the heat of
    argument. . . . Thus, as the state’s advocate, a prose-
    cutor may argue the state’s case forcefully, [provided
    the argument is] fair and based upon the facts in evi-
    dence and the reasonable inferences to be drawn there-
    heightened duty to avoid argument that strays from the
    evidence or diverts the jury’s attention from the facts
    of the case. [The prosecutor] is not only an officer of
    the court, like every attorney, but is also a high public
    officer, representing the people of the [s]tate, who seek
    impartial justice for the guilty as much as for the inno-
    cent. . . . While the privilege of counsel in addressing
    the jury should not be too closely narrowed or unduly
    hampered, it must never be used as a license to state,
    or to comment upon, or to suggest an inference from,
    facts not in evidence, or to present matters which the
    jury [has] no right to consider.’’ (Internal quotation
    marks omitted.) State v. Reddick, 
    174 Conn. App. 536
    ,

    200 L. Ed. 2d 285
    (2018).
    With the foregoing in mind, I address each of the
    defendant’s claims of prosecutorial impropriety in turn
    to determine whether any improprieties occurred.
    A
    The defendant first claims that the prosecutor
    improperly denigrated defense counsel during his clos-
    ing argument. Specifically, he claims that the prosecu-
    tor’s remarks improperly implied that defense counsel
    was employing standard tactics used in all trials. The
    state counters that the prosecutor’s comments were
    proper because they challenged the theory of the
    defense.
    ‘‘It has been held improper for the prosecutor to
    impugn the role of defense counsel. . . . In particular,
    [i]t is improper for a prosecutor to tell a jury, explicitly
    or implicitly, that defense counsel is employing stan-
    dard tactics used in all trials, because such an argument
    relies on facts not in evidence and has no bearing on
    the issue before the jury, namely, the guilt or innocence
    of the defendant. . . . There is a distinction [however]
    between argument that disparages the integrity or role
    of defense counsel and argument that disparages a the-
    ory of defense. . . .
    ‘‘Closing arguments of counsel . . . are seldom care-
    fully constructed in toto before the event; improvisation
    frequently results in syntax left imperfect and meaning
    less than crystal clear. . . . [S]ome leeway must be
    afforded to the advocates in offering arguments to the
    jury in final argument. . . . [C]ounsel must be allowed
    a generous latitude in argument . . . .’’ (Citations omit-
    ted; internal quotation marks omitted.) State v. Fasa-
    nelli, 
    163 Conn. App. 170
    , 180, 
    133 A.3d 921
    (2016).
    In Fasanelli, the defendant argued ‘‘that the prosecu-
    tor improperly denigrated defense counsel by implying
    that defense counsel was being deceitful and using stan-
    dard defense tactics’’ during his closing argument 
    Id., 181. This
    court concluded, however, that the challenged
    comments, when read in context, ‘‘did not attack
    defense counsel; rather, each of the challenged com-
    ments attacked the theory of the defendant . . . .’’ 
    Id., 182. Because
    the prosecutor’s comments were based
    on evidence in the record and attacked only the theory
    of the defense, the court concluded that they were
    proper. 
    Id. In the
    present case, the prosecutor stated the follow-
    ing during his initial closing argument: ‘‘Now, [defense
    counsel’s] going to get up here, I assume, [and say] that
    the Hartford police are lying, [Detective] Reggie Early
    lied, you know, that was a deceitful tactic that he used,
    you know, that’s—if he lies that way, why should you
    believe any of his testimony? Whatever. Completely
    predictable. When your back [is] up against the wall,
    that’s what the defense is going to be. Always blame
    the police, all right.’’
    Similarly to Fasanelli, when read in context these
    comments are clearly based on evidence in the record
    and attack the apparent theory of the defense, as shown
    during defense counsel’s cross-examination. The prose-
    cutor’s comments were directed to defense counsel’s
    attempts during trial to attack the credibility of the
    Hartford police, particularly, Detective Early’s testi-
    mony regarding the manner in which he secured the
    defendant’s confession. The defendant’s apparent the-
    ory was that, because Early had secured the defendant’s
    confession by using a fabricated confession from Har-
    ris, he must not have been truthful in the remainder
    of his testimony. In light of this defense theory, the
    prosecutor’s comments in attacking it were not
    improper.
    B
    The defendant next claims that the prosecutor
    improperly made substantive use of Harris’ tape-
    recorded phone conversation with his mother that was
    recorded by the Department of Correction in accor-
    dance with its usual policy. Some of Harris’ statements
    were admitted by the court as prior inconsistent state-
    ments to impeach his trial testimony. Subsequently,
    during the prosecutor’s initial closing argument, the
    prosecutor referenced the tape-recorded conversation,
    which had not been admitted as a full exhibit for all
    purposes, and then repeated to the jury what Harris
    had said to his mother during the phone call for the truth
    of the statements. In particular, the prosecutor stated:
    ‘‘One point in [Harris’] testimony that he’s talking to
    his mom: First, I think I am being charged with every-
    thing [the defendant] is. Cop told me the warrant is for
    not cooperating, and I’m like, yeah, I’ll take that. Makes
    sense. If you woulda seen the video they showed me,
    I coulda got charged with the same thing [the defen-
    dant] got charged with. They showed me the video.
    . . . They showed everything. When I sat down, when
    I couldn’t move, they showed [the defendant] walked
    up to me. Then they showed him run off. Then they
    show this girl run out, tie my leg up. They showed the
    whole thing. . . .
    ‘‘He testified that [he and the defendant were]
    arrested at the same time, that they were at [the] Hart-
    ford lockup at the police department, and they were
    placed in cells next to each other. They smacked [the
    defendant] with the charges right there. They had us
    together. They really put us together and this ‘n’ shot
    me. . . . And then [Harris] laughs. I’m in a holding cell.
    I don’t know how [the defendant] seen me. I’m asleep.
    [The defendant] seen me. They put [the defendant] in
    a cell like two cells down. It’s like, one, two in the
    morning. All I hear is: George. George. Come on, man.
    I know you hear me. I know you hear me. I just seen
    you. I just seen you. I’m like, this ‘n’ really trying to
    talk to me? I’m in jail ‘cause of him right now ‘cause
    he shot me in the leg.
    ‘‘That’s testimony, ladies and gentlemen. That’s not
    given to police or the state’s attorney’s office.’’ (Empha-
    sis added.)
    Our Supreme Court has adopted a rule ‘‘allowing the
    substantive use of prior written inconsistent state-
    ments, signed by the declarant, who has personal
    knowledge of the facts stated, when the declarant testi-
    fies at trial and is subject to cross examination.’’ State
    v. Whelan, 
    200 Conn. 743
    , 753, 
    513 A.2d 86
    , cert. denied,
    
    479 U.S. 994
    , 
    107 S. Ct. 597
    , 
    93 L. Ed. 2d 598
    (1986). In
    Whelan, the court also held that ‘‘[p]rior oral statements
    of a witness, easily manufactured and often difficult
    to rebut, should not be used to prove an element of a
    crime essential to guilt.’’ (Emphasis added.) 
    Id., 754. In
    the years following Whelan, our Supreme Court has
    recognized that ‘‘the general rationale of Whelan con-
    cerning written statements also applies to tape-
    recorded statements . . . [and that] the requirement
    that such statements be signed is unnecessary because
    the recording of the witness’ voice imparts the same
    measure of reliability as a signature.’’ (Citation omit-
    ted.) State v. Woodson, 
    227 Conn. 1
    , 21, 
    629 A.2d 386
    (1993). Additionally, this court has stated that a witness’
    identification of his or her own voice on tape is afforded
    ‘‘the same measure of reliability as a signature.’’ (Inter-
    nal quotation marks omitted.) State v. Perry, 48 Conn.
    App. 193, 199–200, 
    709 A.2d 564
    , cert. denied, 
    244 Conn. 931
    , 
    711 A.2d 729
    (1998); see also E. Prescott, Tait’s
    Handbook of Connecticut Evidence (6th Ed. 2019)
    § 8.27.3 (b), p. 606. The Whelan rule and its subsequent
    developments and clarifications have been incorpo-
    rated into § 8-5 (1) of the Connecticut Code of Evidence,
    which states that prior inconsistent statements are not
    excluded by the hearsay rule, ‘‘provided (A) the state-
    ment is in writing or otherwise recorded by audiotape,
    videotape or some other equally reliable medium, (B)
    the writing or recording is duly authenticated as that
    of the witness, and (C) the witness has personal knowl-
    edge of the contents of the statement.’’ See also Conn.
    Code Evid. § 8-5 (1), commentary.
    In Woodson, the state had played a tape recording of
    a witness’ statement to police to show its inconsistency
    with the witness’ in-court testimony, in which he had
    disavowed any knowledge of the tape-recorded state-
    ments. See State v. 
    Woodson, supra
    , 
    227 Conn. 1
    9. Sub-
    sequently, the trial court admitted the taped statement
    into evidence and had portions of it played for the jury.
    
    Id. Our Supreme
    Court ultimately concluded that the
    trial court properly admitted the prior inconsistent
    statement for substantive purposes. 
    Id., 23. In
    the pre-
    sent case, although the state similarly played the tape-
    recorded statement made by Harris to his mother to
    show its inconsistency with his in-court testimony that
    he did not remember who shot him, the state did not
    attempt to admit the tape recording into evidence as a
    full exhibit. Rather, the state made clear that the tape-
    recording was not being offered for its truth, but only
    to show its inconsistency with Harris’ testimony. More-
    over, the court made clear in its instructions to the jury,
    after the tape recording was played, that the jurors
    should consider it only as it related to his credibility
    and that it was not substantive evidence.
    As such, the prosecutor’s two references in closing
    argument to Harris’ statements in the tape recording
    for their truth were improper because the statements
    had not been previously admitted as substantive evi-
    dence. The prosecutor, therefore, improperly utilized
    Harris’ recorded statements in his closing argument.
    C
    The defendant next claims that the prosecutor
    improperly expressed his opinion about the credibility
    of two of the state’s witnesses, Harris and Joaquin Ced-
    eno, both of whom were victims of the shooting.
    ‘‘[A] prosecutor may not express his [or her] own
    opinion, directly or indirectly, as to the credibility of
    the witnesses. . . . Such expressions of personal opin-
    ion are a form of unsworn and unchecked testimony,
    and are particularly difficult for the jury to ignore
    because of the prosecutor’s special position. . . .
    However, [i]t is not improper for the prosecutor to
    comment upon the evidence presented at trial and to
    argue the inferences that the jurors might draw there-
    from . . . . We must give the jury the credit of being
    able to differentiate between argument on the evidence
    and attempts to persuade them to draw inferences in
    the state’s favor, on one hand, and improper unsworn
    testimony, with the suggestion of secret knowledge, on
    the other hand. . . . [W]e must look at the statement,
    including the use of the pronoun I, as a whole, in
    determining whether it was an expression of the state’s
    attorney’s personal opinion regarding the credibility of
    witnesses.’’ (Citation omitted; internal quotation marks
    omitted.) State v. 
    Fasanelli, supra
    , 
    163 Conn. App. 185
    –86.
    During his initial closing argument, the prosecutor
    made the following comments: ‘‘You can listen back to
    George Harris’ testimony. It was painful. He would lis-
    ten to part of the tape. Is that you? Yes it is. And did
    you say that? And right after listening to the tape, he
    would say no, okay. He was an obstructionist.’’ In addi-
    tion, during his initial closing argument, the prosecutor
    stated: ‘‘But again, the problem is, [the police] are deal-
    ing with obstructionists like Joaquin Cedeno and
    George Harris. Complete obstructionists.’’ During his
    rebuttal closing argument, the prosecutor stated: ‘‘I
    have to comment on Mr. Cedeno and Mr. Harris. The
    only thing that they’re up here for, what I put them on
    for—because they are obstructionists—just to let you
    know that they got shot.’’ Finally, during rebuttal the
    prosecutor stated: ‘‘If Harris and Cedeno want to be
    obstructionists to our criminal justice system, let it be.
    So be it.’’
    The prosecutor’s comments were not improper. The
    comments were based on Harris’ and Cedeno’s testi-
    mony adduced at trial and reflect an effort on the part of
    the prosecutor to invite the jury to draw the reasonable
    inference that their testimony regarding the incident
    lacked credibility. See State v. Richard W., 115 Conn.
    App. 124, 135–36, 
    971 A.2d 810
    (‘‘[i]t is without question
    that a prosecutor may fairly comment on evidence and
    the reasonable inferences to be drawn therefrom that
    lead the jury to a conclusion as to the credibility of
    witnesses’’ [internal quotation marks omitted]), cert.
    denied, 
    293 Conn. 917
    , 
    979 A.2d 493
    (2009). Specifically,
    because the prosecutor had established during the trial
    that Harris and Cedeno were friends and that the defen-
    dant and Harris were friends, the jury could have drawn
    a reasonable inference from Harris’ impeachment by
    his prior inconsistent statements to his mother that he
    was lying to obstruct the prosecution of the defendant
    and to protect himself, Cedeno, and the defendant. The
    prosecutor’s comments that Harris and Cedeno were
    obstructionists, therefore, were not based solely on the
    prosecutor’s personal opinion, but on the plausible
    motives that they may have had to protect themselves
    and the defendant. See State v. Stevenson, 
    269 Conn. 563
    , 584–85, 
    849 A.2d 626
    (2004); 
    id., 585 (‘‘[i]t
    is not
    improper for a prosecutor to remark on the motives
    that a witness may have to lie’’ [internal quotation marks
    omitted]); see also State v. Thompson, 
    266 Conn. 440
    ,
    466, 
    832 A.2d 626
    (2003) (same). The prosecutor, there-
    fore, did not improperly express his personal opinion
    regarding the credibility of Harris and Cedeno.
    D
    The defendant next claims that the prosecutor
    improperly (1) appealed to the jurors’ emotions and (2)
    injected extraneous matters into the trial.
    ‘‘It is well established that [a] prosecutor may not
    appeal to the emotions, passions and prejudices of the
    jurors. . . . [S]uch appeals should be avoided because
    they have the effect of diverting the [jurors’] attention
    from their duty to decide the case on the evidence. . . .
    When the prosecutor appeals to emotions, he invites
    the jury to decide the case, not according to a rational
    appraisal of the evidence, but on the basis of powerful
    and irrelevant factors which are likely to skew that
    appraisal. . . . [I]n deciding cases [however] . . .
    [j]urors are not expected to lay aside matters of com-
    mon knowledge or their own observations and experi-
    ences, but rather, to apply them to the facts as presented
    to arrive at an intelligent and correct conclusion. . . .
    Therefore, it is entirely proper for counsel to appeal to
    [the jurors’] common sense in closing remarks.’’ (Cita-
    tion omitted; internal quotation marks omitted.) State

    cert. denied, 
    310 Conn. 936
    , 
    79 A.3d 889
    (2013). ‘‘An
    improper appeal to the jurors’ emotions can take the
    form of a personal attack on the defendant’s character
    . . . or a plea for sympathy for the victim or [his or]
    her family.’’ (Internal quotation marks omitted.) State
    v. Santiago, 
    143 Conn. App. 26
    , 34, 
    66 A.3d 520
    (2013).
    In addition, ‘‘[a] prosecutor, in fulfilling his duties,
    must confine himself to the evidence in the record. . . .
    [T]he privilege of counsel in addressing the jury . . .
    must never be used as a license to state, or to comment
    upon, or even to suggest an inference from, facts not
    in evidence, or to present matters which the jury [has]
    no right to consider.’’ (Citation omitted; internal quota-
    tion marks omitted.) State v. Barry 
    A., supra
    , 145 Conn.
    App. 605.
    In the present case, the defendant takes issue with
    the following statements made by the prosecutor during
    his rebuttal closing argument:
    ‘‘If Harris and Cedeno want to be obstructionists to
    our criminal justice system, let it be. So be it. But the
    state is not going to sit back and let people like Cedeno
    and Harris dictate that if they don’t want to come into
    the court, we’re not going to prosecute. They don’t
    decide the criminal justice system, okay. We’re not
    going to sit back just because I don’t care and I’m not
    saying who did it. The state’s not going to sit back and
    say, okay, that’s fine, move on. The state’s going to
    press on by other means.
    ‘‘Does the state have an interest in the case? You bet
    we do. Two people were critically injured, shot by this
    defendant who illegally possessed a firearm, who inten-
    tionally and with extreme indifference to human life
    fired it in a residential neighborhood. A community,
    regardless of a person’s ethnic or economic back-
    ground, has a right, a privilege, to not be subjected to
    this violent, criminal conduct.’’
    The defendant argues that the statements improperly
    urged the jurors to find him guilty to ensure that Harris
    and Cedeno would not get away with manipulating the
    criminal justice system through their ‘‘deliberate
    obstructionism,’’ and to protect the ethnically diverse
    and economically disadvantaged community in which
    they lived. As previously set forth in part I C of this
    concurring opinion, the prosecutor’s comments refer-
    ring to Harris and Cedeno as obstructionists were not
    improper because they were appropriately based on
    evidence adduced during trial. Moreover, the prosecu-
    tor’s comments referencing the community were not
    directed at urging the jury to find the defendant guilty
    because of the location of the incident, but rather, urged
    the jury to remember that all communities have a gen-
    eral right to be free from the violence that occurred in
    this case. The prosecutor did not state that there was
    a greater reason to convict the defendant because of
    the particular location of the incident, nor did he urge
    the jury to have sympathy for the victims because of
    who they were or where they were from. Compare State
    v. Payne, 
    260 Conn. 446
    , 463, 
    797 A.2d 1088
    (2002)
    (finding prosecutor’s statement improper where he indi-
    cated that only guilty verdict would protect legal sys-
    tem), and State v. 
    Santiago, supra
    , 
    143 Conn. App. 41
    –42
    (prosecutor improperly appealed to emotions of jurors
    where he urged them to decide case on basis of sympa-
    thy for victim and victim’s family), with State v. Long,
    
    293 Conn. 31
    , 60, 
    975 A.2d 660
    (2009) (prosecutor’s
    remark not improper where it neither disparaged defen-
    dant nor painted victim as particularly vulnerable or
    deserving of sympathy, but instead was based on evi-
    dence presented at trial). The prosecutor’s statements,
    therefore, neither appealed to the jurors’ emotions nor
    injected extraneous matters into the trial.
    E
    Because the prosecutor committed an impropriety by
    making substantive use of Harris’ prior oral inconsistent
    statements during his closing argument, the question
    of whether that established impropriety ‘‘so infected
    the trial with unfairness as to make the resulting convic-
    tion a denial of due process’’ must be examined. (Inter-
    nal quotation marks omitted.) State v. Williams, 
    204 Conn. 523
    , 539, 
    529 A.2d 653
    (1987).
    ‘‘In determining whether prosecutorial [impropriety]
    was so serious as to amount to a denial of due process,
    this court, in conformity with courts in other jurisdic-
    tions, has focused on several factors. Among them are
    the extent to which the [impropriety] was invited by
    defense conduct or argument . . . the severity of the
    [impropriety] . . . the frequency of the [impropriety]
    . . . the centrality of the [impropriety] to the critical
    issues in the case . . . the strength of the curative mea-
    sures adopted . . . and the strength of the state’s
    case.’’ (Citations omitted.) 
    Id., 540. ‘‘[T]he
    burden is on
    the defendant to show, not only that the remarks were
    improper, but also that, considered in light of the whole
    trial, the improprieties were so egregious that they
    amounted to a denial of due process.’’ State v. 
    Payne, supra
    , 
    303 Conn. 563
    .
    As to whether the prosecutor’s improper references
    to Harris’ prior inconsistent statements were invited by
    defense counsel, the record reflects that the references
    were made during the prosecution’s initial closing argu-
    ment and not in response to statements that defense
    counsel made in his closing argument. Thus, these com-
    ments could not have been invited by the defendant.
    See State v. Ceballos, 
    266 Conn. 364
    , 409–10, 
    832 A.2d 14
    (2003) (‘‘[T]he state’s attorney’s improper comments
    during summation, were not invited by the arguments
    of defense counsel. . . . As the defendant correctly
    points out, the state’s attorney made the challenged
    . . . comments during his initial summation, and not
    during the state’s rebuttal to the defendant’s closing
    argument.’’ [Citation omitted; emphasis in original.]).
    As such, this factor favors the defendant.
    Additionally, the factor regarding the centrality of the
    impropriety to the critical issues in the case also favors
    the defendant. The prosecutor’s assertion during his
    closing argument that Harris’ prior inconsistent state-
    ment placed the defendant at the scene of the shooting
    went to the defendant’s identification as the shooter,
    which was a crucial issue in this case.
    With respect to the frequency of the impropriety,
    the prosecutor’s substantive references to Harris’ prior
    inconsistent statements were not frequent. The prose-
    cutor’s references regarding the identification of the
    defendant in Harris’ prior inconsistent statements
    occurred only during the prosecutor’s initial summa-
    tion. See State v. Ross, 
    151 Conn. App. 687
    , 701, 
    95 A.3d 1208
    (‘‘the claimed improprieties were not pervasive
    throughout the trial, but were confined to, and consti-
    tuted only a small portion of, closing and rebuttal argu-
    ment, a part of the trial where we typically allow some
    latitude’’ [internal quotation marks omitted]), cert.
    denied, 
    314 Conn. 926
    , 
    101 A.3d 271
    , 272 (2014). Accord-
    ingly, the frequency factor favors the state.
    As to the sufficiency of curative measures taken by
    the court, the court provided jury instructions indicat-
    ing that the prosecutor was not permitted to give an
    opinion as to the defendant’s guilt, that it was the role
    of the jury to find the facts, and that witness credibility
    was an issue solely for the jury. Additionally, the court
    instructed the jury during Harris’ direct examination
    that it ‘‘should consider that out-of-court evidence only
    as it relates to [the witness’] credibility’’ and that ‘‘[i]t’s
    not substantive evidence.’’ The court later repeated
    these instructions, directing the jury that it ‘‘should
    consider this evidence only as it relates to the credibility
    of the witness’ testimony, not as substantive evidence.’’
    Furthermore, there is no suggestion in the present case
    that the jury failed to follow the court’s instructions.
    ‘‘In the absence of a showing that the jury failed or
    declined to follow the court’s instructions, we presume
    that it heeded them.’’ (Internal quotation marks omit-
    ted.) State v. 
    Thompson, supra
    , 
    266 Conn. 485
    .
    The defendant argues that the court’s ‘‘general
    instructions were not sufficient to cure the prejudicial
    impact of the improper arguments.’’ Even if the court’s
    instructions were found to be insufficient, however,
    ‘‘the defendant, by failing to bring [specific curative
    instructions] to the attention of the trial court, bears
    much of the responsibility for the fact that these claimed
    improprieties went uncured.’’ (Internal quotation marks
    omitted.) State v. 
    Thompson, supra
    , 
    266 Conn. 483
    . As
    such, the defendant’s failure to object to the prosecu-
    tor’s reference to Harris’ prior inconsistent statement
    creates a presumption that the defendant did not view
    the impropriety as prejudicial enough to affect his right
    to a fair trial. See 
    id., 479–80 (‘‘[W]e
    consider it highly
    significant that defense counsel failed to object to any
    of the improper remarks, request curative instructions,
    or move for a mistrial. Defense counsel, therefore, pre-
    sumably [did] not view the alleged impropriety as preju-
    dicial enough to jeopardize seriously the defendant’s
    right to a fair trial. . . . Given the defendant’s failure to
    object, only instances of grossly egregious misconduct
    will be severe enough to mandate reversal.’’ [Citation
    omitted; emphasis added; internal quotation marks
    omitted.]).
    Although the defendant concedes that he failed to
    object to the prosecutor’s allegedly improper state-
    ments when or after they were made, he argues that
    the resulting impropriety was so severe as to deprive
    him of a fair trial. Because the prosecutor’s substantive
    references to Harris’ prior inconsistent statements were
    not frequent, and the defendant failed to object to them,
    the prosecutor’s substantive references to Harris’ prior
    inconsistent statements were not grossly egregious
    enough to warrant reversal. See 
    id., 480 (‘‘[g]iven
    the
    defendant’s failure to object, only instances of grossly
    egregious misconduct will be severe enough to mandate
    reversal’’); see also State v. 
    Ross, supra
    , 
    151 Conn. App. 700
    (defendant not entitled to prevail if ‘‘the claimed
    [impropriety] was not blatantly egregious and merely
    consisted of isolated and brief episodes that did not
    reveal a pattern of conduct repeated throughout the
    trial’’ [emphasis added; internal quotation marks
    omitted]).
    As to the strength of the state’s case, the prosecutor
    conceded in his argument to the jury that the video of
    the shooting, which was shown to the jury and had
    been obtained from nearby security cameras, was not
    enough for the jury to return a verdict of guilty, but
    pointed to other ways the state could corroborate the
    defendant’s identification, such as ‘‘clothes, Officer
    [Robert] Fogg [of the Hartford Police Department], the
    timing coincidence, George Harris, the video and the
    reasonable inferences you can draw from it, and Detec-
    tive Reggie Early.’’ Specifically, the record reveals that
    Officer Fogg’s testimony placed the defendant at the
    scene ten minutes after the shooting, and the video
    footage showed the figure who committed the shooting
    in clothes similar to what the defendant was wearing
    when he arrived on the scene. Furthermore, the prose-
    cutor had properly impeached Harris’ credibility by pre-
    senting his prior inconsistent statements through the
    tape-recorded phone conversation he had engaged in
    with his mother. Thus, the jury reasonably could have
    inferred that Harris was untruthful when he responded
    to the question about whether the defendant was at the
    scene of the shooting when it occurred, but, of course,
    the jury could not have concluded solely from those
    prior inconsistent statements that the facts supporting
    them were true. Additionally, the defendant admitted,
    albeit as a result of the confession allegedly made by
    Harris that had been fabricated by and read to the
    defendant by Early, that he was the shooter. See State
    v. Camacho, 
    282 Conn. 328
    , 383, 
    924 A.2d 99
    (state’s
    case strong where, among other evidence, defendant
    admitted he had shot woman), cert. denied,

    , 
    128 S. Ct. 388
    , 
    169 L. Ed. 2d 273
    (2007). As such,
    this factor favors the state.
    Because the Williams factors primarily favor the
    state, the defendant has failed to prove that the prosecu-
    tor’s improper substantive use of Harris’ prior inconsis-
    tent statement violated his rights to due process and a
    fair trial.
    II
    BRADY VIOLATION
    The defendant next claims that the state withheld
    material evidence regarding Early’s credibility in viola-
    tion of Brady v. Maryland, 
    373 U.S. 83
    , 87, 
    83 S. Ct. 1194
    , 
    10 L. Ed. 2d 215
    (1963). Specifically, the defendant
    claims that the state deprived him of the right to cross-
    examine Early in regard to a Hartford Police Depart-
    ment internal affairs report detailing his misconduct,
    which was totally unrelated to the criminal incident
    involving the defendant and Harris, stemming from an
    encounter with a towing company. The state argues that
    the report was neither favorable nor material because
    it was not probative of Early’s untruthfulness, and it
    was not reasonably probable that use of the report
    would have changed the result of this case.
    The following additional facts are relevant to the
    disposition of this claim. The defendant alleges that,
    subsequent to the parties’ filing of their initial briefs,
    he became aware of an internal affairs report involving
    Early through a January 24, 2017 article published by
    the Journal Inquirer newspaper. The report detailed a
    2007 investigation conducted by the Hartford Police
    Department to determine whether Early had abused his
    position as a police officer in attempting to convince
    a towing company to release his car without charging
    him a fee, and whether he intentionally misled the inves-
    tigation by giving a false statement as to who drove
    him to the towing company. The report stated that an
    internal affairs sergeant sustained the charge of abuse
    of police powers as well as the allegation that Early
    intentionally made a false statement to investigators.
    The report further stated that Early was issued a written
    reprimand for abusing his position as a police officer
    but was not disciplined for making the false statements,
    as they did not appear aimed at misleading the investi-
    gation.
    On February 10, 2017, after discovering the report,
    the defendant filed a motion for permission to file a
    late motion for augmentation and rectification of the
    record with this court in order to establish a Brady
    claim. Specifically, the defendant sought an evidentiary
    hearing to determine whether the state had failed to
    disclose an internal affairs investigation relating to
    Early at the time of trial and requested that the trial
    court mark the report as an exhibit. On February 27,
    2017, the state filed a response to the defendant’s
    motion, conceding the facts on which the defendant
    relied to establish his Brady claim and not opposing
    rectification of the record. The state further conceded
    that the report had been in the possession of the Hart-
    ford Police Department but had not been disclosed by
    the state prior to or during trial. Accordingly, the state
    argued that because suppression of the report was not
    a contested factual issue, an evidentiary hearing was
    not necessary. On March 15, 2017, this court granted
    the defendant’s motion for permission and ordered the
    defendant to formally file his motion. On March 21,
    2017, the defendant filed a revised motion for augmen-
    tation and rectification of the record with the trial court,
    in which he agreed with the state that an evidentiary
    hearing was not necessary due to the state’s conces-
    sions. On November 6, 2017, the court granted the
    defendant’s motion and marked the report as an exhibit.
    ‘‘It is the duty of the state voluntarily to disclose
    material in its exclusive possession which would be
    exonerative or helpful to the defense . . . . The prose-
    cution’s duty to disclose applies to all material and
    exculpatory evidence that is within its possession or
    available to it . . . and that the prosecution knew or
    should have known was exculpatory. . . . To prove a
    Brady violation, therefore, the [defendant] must estab-
    lish: (1) that the state suppressed evidence (2) that was
    favorable to the defense and (3) material either to guilt
    or to punishment. . . . If the [defendant] fails to meet
    his burden as to one of the three prongs of the Brady
    test, then we must conclude that a Brady violation has
    not occurred.’’ (Citations omitted; internal quotation
    marks omitted.) Peeler v. Commissioner of Correction,

    , cert. denied,
    
    325 Conn. 901
    , 
    157 A.3d 1146
    (2017). Moreover,
    ‘‘[w]hether the [defendant] was deprived of his due
    process rights due to a Brady violation is a question
    of law, to which we grant plenary review.’’ (Internal
    quotation marks omitted.) 
    Id., 689. In
    the present case, the state has conceded that the
    internal affairs report was ‘‘suppressed within the mean-
    ing of Brady and its progeny.’’ (Internal quotation marks
    omitted.) As such, the inquiry becomes whether the
    report was favorable to the defendant and material to
    his guilt or his punishment. ‘‘The United States Supreme
    Court . . . has recognized that [t]he jury’s estimate of
    the truthfulness and reliability of a . . . witness may
    well be determinative of guilt or innocence, and it is
    upon such subtle factors as the possible interest of the
    witness in testifying falsely that a defendant’s life or
    liberty may depend. . . . Accordingly, the Brady rule
    applies not just to exculpatory evidence, but also to
    impeachment evidence . . . which, broadly defined, is
    evidence having the potential to alter the jury’s assess-
    ment of the credibility of a significant prosecution wit-
    ness.’’ (Citations omitted; internal quotation marks
    omitted.) Adams v. Commissioner of Correction, 
    309 Conn. 359
    , 369–70, 
    71 A.3d 512
    (2013).
    The defendant argues that the false statements that
    Early made to investigators detailed in the report are
    specific acts of misconduct that were essential to the
    defense in order to impeach his credibility. The state
    argues that because the Hartford Police Department
    ultimately did not uphold the finding made by the
    investigating internal affairs sergeant that Early had
    intentionally made false statements, an inference of
    untruthfulness stemming from the statements ‘‘was at
    best very low.’’
    Section 6-6 (b) (1) of the Connecticut Code of Evi-
    dence provides that ‘‘[a] witness may be asked, in good
    faith, about specific instances of conduct of the witness,
    if probative of the witness’ character for untruthful-
    ness.’’ Moreover, ‘‘[t]his court does not retry the case
    or evaluate the credibility of the witnesses. . . .
    Rather, we must defer to the [trier of fact’s] assessment
    of the credibility of the witnesses based on its firsthand
    observation of their conduct, demeanor and attitude.’’
    (Internal quotation marks omitted.) Elsey v. Commis-
    sioner of Correction,

    , 153,

    , cert. denied, 
    300 Conn. 922
    , 
    14 A.3d 1007
    (2011).
    In the present case, the fact that Early was accused of
    intentionally lying and was initially found to have done
    so by the investigating internal affairs sergeant was
    impeachment evidence that was favorable to the
    defense. It would have been within the jury’s province to
    assess Early’s credibility on the basis of the accusations
    contained within the report. This court’s acceptance of
    the state’s argument would be tantamount to preventing
    a jury from conducting this assessment. Because the
    internal affairs report would likely bear on the credibil-
    ity of Early, it was potential impeachment evidence and,
    therefore, favorable to the defendant’s position.
    Although the internal affairs report was suppressed
    within the meaning of Brady and was favorable to the
    defense, it was not material under Brady. ‘‘Not every
    failure by the state to disclose favorable evidence rises
    to the level of a Brady violation. Indeed, a prosecutor’s
    failure to disclose favorable evidence will constitute a
    violation of Brady only if the evidence is found to be
    material. The Brady rule is based on the requirement of
    due process. Its purpose is not to displace the adversary
    system as the primary means by which truth is uncov-
    ered, but to ensure that a miscarriage of justice does
    not occur. Thus, the prosecutor is not required to deliver
    his entire file to defense counsel, but only to disclose
    evidence favorable to the accused that, if suppressed,
    would deprive the defendant of a fair trial . . . .
    United States v. Bagley, [
    473 U.S. 667
    , 675, 
    105 S. Ct. 3375
    , 
    87 L. Ed. 2d 481
    (1985)]. In a classic Brady case,
    involving the state’s inadvertent failure to disclose
    favorable evidence, the evidence will be deemed mate-
    rial only if there would be a reasonable probability of
    a different result if the evidence had been disclosed.
    Bagley’s touchstone of materiality is a reasonable prob-
    ability of a different result, and the adjective is
    important. The question is not whether the defendant
    would more likely than not have received a different
    verdict with the evidence, but whether in its absence
    he received a fair trial, understood as a trial resulting
    in a verdict worthy of confidence. A reasonable proba-
    bility of a different result is accordingly shown when
    the government’s evidentiary suppression undermines
    confidence in the outcome of the trial.’’ (Internal quota-
    tion marks omitted.) Adams v. Commissioner of Cor-
    
    rection, supra
    , 
    309 Conn. 370
    –71.
    In the present case, the defendant argues that the
    internal affairs report was material because Early’s tes-
    timony was the state’s most compelling evidence and,
    therefore, the defendant’s ability to cross-examine
    Early with his own statements impacted the fairness
    of the trial. The state argues that the report was not
    material because it had little probative value for pur-
    poses of casting doubt on Early’s investigation and the
    defendant’s confession, the defendant had impeached
    Early by other means, including his fabrication of the
    purported Harris confession, and the state’s evidence
    was strong.
    The state’s failure to disclose the report to allow the
    defendant yet another opportunity to impeach Early’s
    credibility, viewed in the context of the entire trial,
    does not undermine confidence in the jury’s verdict.
    As previously discussed in part I E of this concurring
    opinion, there was sufficient evidence in the record
    to support the defendant’s conviction, namely, Officer
    Fogg’s testimony that placed the defendant at the scene
    ten minutes after the shooting; video footage that
    showed the shooter in clothes similar to what the defen-
    dant was wearing when he arrived on the scene; Harris’
    prior inconsistent statements allowing the jury to infer
    his lack of credibility; and the defendant’s confession
    that he was the shooter. See Elsey v. Commissioner
    of Cor
    rection, supra
    , 
    126 Conn. App. 160
    (‘‘[T]here was
    ample evidence to support the petitioner’s conviction.
    . . . Therefore, we cannot say that the fact that the
    state did not disclose the evidence . . . undermines
    our confidence in the jury’s verdict.’’ [Citation omit-
    ted.]). As previously set forth, Early’s credibility had
    been impeached during his cross-examination when the
    defense questioned him regarding his admitted fabrica-
    tion of Harris’ purported confession, which, in turn, led
    to the defendant’s confession. See Morant v. Commis-
    sioner of Correction, 
    117 Conn. App. 279
    , 299, 
    979 A.2d 507
    (‘‘[t]his evidence . . . taken in context is merely
    cumulative impeachment evidence and, therefore, not
    material under Brady’’), cert. denied, 
    294 Conn. 906
    ,
    
    982 A.2d 1080
    (2009).
    Because the state’s evidence was sufficient for the
    jury to find the defendant guilty, and because the evi-
    dence contained in the report was at best cumulative
    concerning Early’s credibility, the internal affairs report
    was not material within the meaning of Brady. Accord-
    ingly, the defendant’s Brady claim fails.
    III
    PLAIN ERROR
    The defendant next claims that the state’s agreement
    with Harris not to prosecute Harris for any future acts
    of perjury committed while testifying for the state at
    the defendant’s trial constituted plain error because (1)
    it clearly violated the public policy of this state against
    immunizing perjured testimony and (2) it violated § 54-
    47a.3 The defendant further argues that this improper
    grant of immunity constitutes structural error that obvi-
    ates the need to engage in harmless error analysis. In
    the alternative, the defendant argues that, if harmless
    error analysis applies, the state has failed to meet its
    burden to show that the error was harmless beyond a
    reasonable doubt. The state concedes that its
    agreement not to prosecute Harris for perjury was a
    defective and improper grant of immunity, but argues
    that such error was not structural in nature, nor did it
    cause the defendant manifest injustice.
    The state concedes that its promise not to prosecute
    Harris for perjury in connection with his upcoming testi-
    mony was a defective and improper grant of immunity
    that was inconsistent with Harris’ duty to testify truth-
    fully. The state articulates that plain error analysis
    requires a court not only to examine the nature of the
    error, but also to assess the grievousness of its conse-
    quences and whether it worked a serious and manifest
    injustice on the defendant. The state argues that the
    defendant was not harmed by the grant of immunity to
    Harris because Harris did not state during his testimony
    that the defendant had shot him or Cedeno. The state
    refers to the court’s instructions to the jury that Harris’
    out-of-court statements, including those in which he
    said that the defendant shot him, could not be used
    substantively, but only on the issue of the credibility
    of his in-court testimony. The state also argues that
    there was other evidence to prove the defendant’s guilt,
    and that the jury reasonably could have found, on the
    basis of evidence developed through a witness other
    than Harris, and through the state’s impeachment of
    Harris, that Harris was lying when he testified that he
    did not know who shot him, and that everyone, includ-
    ing the jury, should have seen that. From those facts
    the state concludes that ‘‘the prosecutor’s error did not
    inflict grievous harm causing manifest injustice upon
    the defendant . . . .’’ Although the state refers to Har-
    ris’ immunized testimony before the jury that was per-
    mitted by the court, the state does not discuss the
    court’s role and duty with respect to the truth seeking
    process that is inherent in any trial, and the constitu-
    tional, statutory, public policy and other institutional
    implications and ramifications of a representative of
    the state offering the testimony of a witness, and the
    court’s permitting that testimony to be presented to
    the jury, which both was anticipated and expected to
    contain lies about a crucial issue in the trial, i.e.,
    whether the defendant shot Harris and Cedeno. The
    state also does not discuss the contradiction between
    the grant of immunity that was not disclosed to the jury
    and the usual oath to tell the truth, which Harris took
    before the jury: ‘‘You solemnly swear or solemnly and
    sincerely affirm, as the case may be, that the evidence
    you shall give concerning this case shall be the truth,
    the whole truth and nothing but the truth; so help you
    God or upon penalty of perjury.’’ General Statutes
    § 1-25.
    The following additional facts are relevant to this
    claim. On October 9, 2014, the prosecutor and Harris
    entered into an immunity agreement by which Harris
    was granted transactional immunity for his testimony
    regarding the events on March 28, 2013, the date of the
    shooting, and use immunity, both direct and derivative,
    for all other proceedings. That same day, October 9,
    2014, prior to Harris’ testimony in the defendant’s trial,
    the following exchange occurred between the court,
    Harris’ counsel, and the prosecutor:
    ‘‘[The Court]: All right. And this additional immunity
    agreement signed by the state’s attorney . . . do you
    have any issues on that?
    ‘‘[Harris’ Counsel]: No. That was drafted—I was
    involved in the drafting of that document, Your Honor.
    ‘‘[The Court]: All right.
    ‘‘[Harris’ Counsel]: And so it includes transactional
    immunity to the events related to the—on the day of
    the shooting, directly and indirectly. It involves use
    immunity, so none of his words could be used directly
    against him in this or any other proceeding in state or
    federal court or anywhere else. It also includes deriva-
    tive use so that his words can’t be used to investigate
    and then come up with other evidence that can be used
    against him in any proceeding. . . .
    ‘‘[Harris’ Counsel]: And my understanding is that
    there is a tape recording or the prosecuting authority
    believes that it has a tape recording of my client saying
    something related to his testimony. So, I have concerns
    about exposure to perjury, and my understanding is
    that there has been an agreement that there wouldn’t
    be any perjury prosecution related to my client’s testi-
    mony today.
    ‘‘[The Prosecutor]: That’s correct, Your Honor.
    ‘‘[The Court]: Okay. Well, [counsel], I must compli-
    ment you. I have been in the criminal justice system
    for forty-two and one-half years. I’ve never heard of
    anybody getting that agreement. But it’s an agreement
    the state made. That’s their decision.’’
    During Harris’ direct testimony, when the state
    offered Harris’ tape-recorded phone conversation with
    his mother as a prior inconsistent statement, the follow-
    ing exchange occurred:
    ‘‘[The Prosecutor]: Well, this is the way you could
    refresh his memory, Your Honor.
    ‘‘[The Court]: Well, you’re the one who agreed not to
    prosecute him for perjury.
    ‘‘[The Prosecutor]: I agree.
    ‘‘[The Court]: Which is probably against the public
    interest, but I didn’t step in.
    ‘‘[The Prosecutor]: There’s a lot of issues with public
    interest in this case.
    ‘‘[The Court]: I must say this amount of perjury actu-
    ally offends me.’’
    ‘‘[The plain error] doctrine, codified at Practice Book
    § 60-5,4 is an extraordinary remedy used by appellate
    courts to rectify errors committed at trial that, although
    unpreserved, are of such monumental proportion that-
    they threaten to erode our system of justice and work
    a serious and manifest injustice on the aggrieved party.’’

    , 76–77,

    (2013).
    ‘‘An appellate court addressing a claim of plain error
    first must determine if the error is indeed plain in the
    sense that it is patent [or] readily [discernible] on the
    face of a factually adequate record, [and] also . . .
    obvious in the sense of not debatable. . . . This deter-
    mination clearly requires a review of the plain error
    claim presented in light of the record. Although a com-
    plete record and an obvious error are prerequisites for
    plain error review, they are not, of themselves, suffi-
    cient for its application. . . . [T]he plain error doctrine
    is reserved for truly extraordinary situations [in which]
    the existence of the error is so obvious that it affects
    the fairness and integrity of and public confidence in
    the judicial proceedings. . . . [I]n addition to examin-
    ing the patent nature of the error, the reviewing court
    must examine that error for the grievousness of its
    consequences in order to determine whether reversal
    under the plain error doctrine is appropriate. A party
    cannot prevail under plain error unless it has demon-
    strated that the failure to grant relief will result in mani-
    fest injustice. . . . [Previously], we described the two-
    pronged nature of the plain error doctrine: [An appel-
    lant] cannot prevail under [the plain error doctrine]
    . . . unless he demonstrates that the claimed error is
    both so clear and so harmful that a failure to reverse
    the judgment would result in manifest injustice. . . .
    ‘‘It is axiomatic that, [t]he plain error doctrine . . .
    is not . . . a rule of reviewability. It is a rule of revers-
    ibility. That is, it is a doctrine that this court invokes
    in order to rectify a trial court ruling that, although
    either not properly preserved or never raised at all in
    the trial court, nonetheless requires reversal of the trial
    court’s judgment . . . for reasons of policy. . . . Put
    another way, plain error review is reserved for only
    the most egregious errors. When an error of such a
    magnitude exists, it necessitates reversal.’’5 (Citations

    , 812–14,

    (2017).
    In the present case, the defendant argues that the
    violation of § 54-47a (b) and the public policy against
    immunizing perjured testimony constitutes plain error
    that is structural in nature. The United States Supreme
    Court has recently articulated that ‘‘[t]he purpose of
    the structural error doctrine is to ensure insistence
    on certain basic, constitutional guarantees that should
    define the framework of any criminal trial. Thus, the
    defining feature of structural error is that it affect[s]
    the framework within which the trial proceeds, rather
    than being simply an error in the trial process itself.
    . . . For the same reason, a structural error def[ies]
    analysis by harmless error standards.’’ (Citation omit-

    mental unfairness.’’ (Internal quotation marks omitted.)

    328 Conn. 558
    , 570, 
    181 A.3d 74
    (2018).
    Although structural error most commonly occurs in
    the violation of a constitutional right; see Weaver v.
    
    Massachusetts, supra
    , 
    137 S. Ct. 1908
    (‘‘violation of the
    right to a public trial is a structural error’’); see also
    State v. Lopez, 
    271 Conn. 724
    , 733–34, 
    859 A.2d 898
    (2004) (violation of constitutional right to be present
    during in-chambers inquiry regarding defense counsel’s
    potential conflict of interest was structural error); our
    Supreme Court has also found structural error in the
    form of a statutory violation. See State v. Murray, 
    254 Conn. 472
    , 496–98, 
    757 A.2d 578
    (2000) (substitution
    during jury deliberations of alternate juror who pre-
    viously had been dismissed violated General Statutes
    § 54-82h [c]). In Murray, our Supreme Court overruled
    in part its previous decision in State v. Williams, 
    231 Conn. 235
    , 
    645 A.2d 999
    (1994), which had determined
    that violation of § 54-82 (c) was subject to harmless
    error analysis and concluded ‘‘that the inclusion of a
    nonjuror among the ultimate arbiters of innocence or
    guilt [in violation of § 54-82h (c)] necessarily
    amount[ed] to a [defect] in the structure of the trial
    mechanism that defie[d] harmless error review.’’
    (Emphasis added; internal quotation marks omitted.)
    State v. 
    Murray, supra
    , 498. Accordingly, the court
    endorsed the position that certain statutory violations
    that pervade the entirety of the trial may be subject
    to structural error analysis. ‘‘These so-called structural
    errors tend to by their very nature cast so much doubt
    on the fairness of the trial process that, as a matter of
    law, they can never be considered harmless.’’ (Internal
    quotation marks omitted.) State v. 
    Cushard, supra
    , 
    328 Conn. 570
    .
    Because structural error may occur in the form of a
    statutory violation, structural error analysis is war-
    ranted in the present case. ‘‘[T]o determine if the error
    in the present case was structural, we must perform
    an initial review of the record to determine whether
    the [violation] had any impact on the subsequent trial
    that irretrievably eroded its fundamental fairness.’’
    (Emphasis added.) 
    Id., 578. Under
    both § 54-47a (b)7
    and our Supreme Court case law, immunity for perjured
    or false testimony in a criminal trial is improper. See
    State v. Giraud, 
    258 Conn. 631
    , 634–35, 
    783 A.2d 1019
    (2001) (‘‘[i]mmunity . . . may not be a license to lie
    while giving immunized testimony’’ [internal quotation
    marks omitted]). As previously set forth, the state con-
    cedes that its agreement not to prosecute Harris for
    his perjured testimony at the defendant’s trial was an
    improper and defective grant of immunity. Indeed, the
    record reflects that both the very experienced trial court
    judge and the prosecutor recognized that the breadth
    of the immunity agreement was improper, and probably
    unique, in Connecticut criminal proceedings. As such,
    the issue is whether this improper grant of immunity
    was so fundamentally unfair that it affected the entire
    framework of the defendant’s trial.
    It is axiomatic that ‘‘a primary function of a criminal
    trial is to search for the truth. . . . The trial court has
    a duty to preside at a trial and to take appropriate
    actions, when necessary, that promote truth at the
    trial.’’ (Citation omitted.) State v. Kirker,

    , 617,

    , cert. denied, 
    244 Conn. 914
    , 
    713 A.2d 831

    of a trial is a search for facts and truth . . . a trial must
    also be fair. State v. Corchado, 
    200 Conn. 453
    , 459, 
    512 A.2d 183
    (1986) (discretion to be exercised must be
    informed and guided by considerations of fundamental
    fairness that are ingrained in the concept of due process
    of law).’’ (Internal quotation marks omitted.) State v.
    Allen, 
    205 Conn. 370
    , 379, 
    533 A.2d 559
    (1987). More-
    over, a jury is ‘‘entitled to assume . . . that [a witness’]
    statements carried the sanction of the oath which [the
    witness] had taken . . . .’’ Ruocco v. Logiocco, 
    104 Conn. 585
    , 591, 
    134 A. 73
    (1926). Additionally, the trial
    court’s unwaivable duty to prohibit knowingly perjured
    testimony by a witness in a trial, and the jury’s entitle-
    ment to assume that each witness is providing testi-
    mony under the penalty of perjury, are embodied in the
    language of § 54-47a (b), which explicitly forbids the
    immunization of perjured testimony.
    In the present case, the court knowingly abdicated
    its duty to reject any agreement that facilitated Harris’
    perjured testimony, and it undermined the truth seeking
    purpose of the defendant’s trial by permitting Harris to
    testify without fear of prosecution for perjury.8 The
    defendant’s attorney did not make any objection on the
    record to the immunity agreement between the state
    and Harris. The court, however, appears immediately
    to have accepted the agreement without asking the
    defendant to comment on its validity. The court, as it
    expressed on the record, was fully aware of the impro-
    priety of, and other problematic issues raised by the
    agreement, and it was also aware of and commented
    on Harris’ obviously perjurious testimony after at least
    some of it had occurred. In light of the clear statutory
    invalidity of the agreement, and the other obvious issues
    that were raised by the agreement, the court had a
    clear and unwaivable duty to act to prohibit Harris’
    testimony, even in the absence of any objection by the
    defendant to it, and its failure to do so was plain error.
    Additionally, it is reasonable to conclude, on the basis
    of the record of the trial, that the state provided Harris
    with immunity from perjury in order to use his testi-
    mony as a basis to put Harris’ prior inconsistent state-
    ments in front of the jury, initially to impeach his
    credibility. The state, however, subsequently and in vio-
    lation of its representation to the court that it offered
    the evidence solely for the purpose of impeachment and
    not for the truth of the statements therein, improperly
    utilized those statements for their truth in its closing
    argument. The court’s abdication of its duty to take
    appropriate actions, when necessary, that promoted
    truth finding at the trial by allowing the immunization
    of Harris’ testimony so that he could not be charged with
    and convicted of perjury undermined the fundamental
    fairness of the defendant’s trial.
    If the court, as it should have done pursuant to § 54-
    47a (b) and Connecticut public policy, had rejected
    the agreement for Harris’ testimony, there presumably
    would have been no testimony by Harris before the jury
    about the incident because Harris would have exercised
    his fifth amendment privilege against self-incrimination,
    and there would have been no structural error despite
    the existence of the agreement. Although plain error in
    this case exists solely because of the court’s acceptance
    and implementation of the agreement, which allowed
    the improper, overbroad, and seemingly unprecedented
    immunization of Harris’ testimony that the state antici-
    pated would include perjury; see footnote 2 of this con-
    curring opinion; the collateral consequences of that
    testimony enhance the egregiousness of the improper
    grant of immunity. Had the state not provided Harris
    with immunity for his intentional lies that it anticipated
    were to occur during his testimony, Harris would not
    have testified and, thus, the state would not have
    improperly been able to utilize in its closing argument
    Harris’ prior inconsistent statements against the defen-
    dant in a way that substantively corroborated the state-
    ments made by the defendant in his confession.
    The court’s acceptance and implementation of the
    agreement, which allowed the improper, overbroad
    immunization of Harris’ testimony that was anticipated
    to include lies that amounted to perjury thus constituted
    plain error that was structural in nature. As previously
    set forth, the plain error doctrine is reserved for truly
    extraordinary situations in which the existence of the
    error is so obvious that it affects the fairness and integ-
    rity of and public confidence in the judicial proceedings.
    See State v. 
    McClain, supra
    , 
    324 Conn. 812
    –14. Giving
    a witness a free pass to lie in his sworn testimony
    satisfies that plain error requirement. The defendant
    has demonstrated that the actions of the court and
    the prosecutor resulted in manifest injustice to him;
    perjured testimony is an obvious and flagrant affront
    to the basic concepts of judicial proceedings, as it goes
    to the very heart of the fair administration of justice.

    96 S. Ct. 1768
    , 
    48 L. Ed. 2d 212
    (1976). Accordingly, I
    concur with the majority’s reversal of the defendant’s
    conviction and remand of the case for a new trial, but,
    because of the existence of such structural error, con-
    clude that we do not need to exercise our supervisory
    authority to do so.9
    1
    On December 14, 2017, prior to oral argument before this court, the
    defendant filed a motion requesting supplemental briefing as to his claim
    pursuant to Brady v. Maryland, 
    373 U.S. 83
    , 87, 
    83 S. Ct. 1194
    , 
    10 L. Ed. 2d
    215 (1963), which this court granted on January 11, 2018. On May 31,
    2018, after oral argument, this court ordered, sua sponte, that the parties
    file supplemental briefs addressing whether the state’s agreement not to
    prosecute Harris for any perjury committed while testifying for the state
    constituted plain error. On October 5, 2018, this court again ordered, sua
    sponte, supplemental briefing to address whether this court should exercise
    its supervisory authority to reverse the defendant’s conviction if the grant of
    immunity to Harris for any perjury while testifying for the state was improper.
    2
    The defendant focuses on the actions of the prosecutor in entering into
    the agreement with Harris that violated the public policy of Connecticut
    and General Statutes § 54-47a. Without the acceptance and implementation
    of that agreement by the court in allowing Harris to testify, the agreement
    would have had no effect. I thus interpret the claims of the defendant to
    include the actions of the court in allowing Harris to testify pursuant to the
    illegal and improper agreement.
    3
    In its August 15, 2018 supplemental brief, the defendant argued that
    ‘‘[t]he agreement to immunize Harris from prosecution for any perjury he
    might commit in testifying was plain error, both because it violated public
    policy, and because it violated [§] 54-47a. It is well established that a convic-
    tion obtained by the knowing use of perjured testimony is fundamentally
    unfair. Adams v. Commissioner of Cor
    rection, supra
    , 
    309 Conn. 371
    –73;
    United States v. Agurs, 
    427 U.S. 97
    , 103, 
    96 S. Ct. 2392
    , 
    49 L. Ed. 2d 342
    (1976). . . . By expressly prohibiting grants of immunity for the crime of
    perjury; [General Statutes] § 54-47a; the legislature safeguarded the funda-
    mental rights to a fair trial and to confrontation. U.S. Const., amends. V, VI
    and XIV; Conn. Const., art. I, § 8. . . . Perjured testimony is an obvious
    and flagrant affront to the basic concepts of judicial proceedings; United

    96 S. Ct. 1768
    , 
    48 L. Ed. 2d 212
    (1976); it goes to the very heart of the fair administration of justice. No
    legal system can long remain viable if lying under oath is treated as no more
    than a breach of etiquette. United States v. Cornielle, 
    171 F.3d 748
    , 753 (2d
    Cir. 1999). . . . In the constitutional process of granting immunity to secure
    witness testimony, perjury simply has no place whatever. United States v.
    
    Mandujano, supra
    , 576–77.’’ (Citations omitted; internal quotation marks
    omitted.)
    Although the primary focus of the defendant’s argument is the agreement,
    it is evident from the defendant’s August 15, 2018 supplemental brief that
    the structural harm alleged to be caused to the defendant occurred after
    the court allowed Harris to testify at trial with such an illegal and improper
    grant of immunity that was not disclosed to the jury, which had witnessed
    Harris take the usual oath to tell the truth: ‘‘You solemnly swear or solemnly
    and sincerely affirm, as the case may be, that the evidence you shall give
    concerning this case shall be the truth, the whole truth and nothing but the
    truth; so help you God or upon penalty of perjury.’’ See General Statutes
    § 1-25.
    4
    Practice Book § 60-5 provides in relevant part that ‘‘[t]he court shall not
    be bound to consider a claim unless it was distinctly raised at the trial or
    arose subsequent to the trial. The court may in the interests of justice notice
    plain error not brought to the attention of the trial court. . . .’’

    In Weaver, the court set forth what it referred to as ‘‘at least three broad
    rationales’’ for applying structural error analysis:
    ‘‘First, an error has been deemed structural in some instances if the right
    at issue is not designed to protect the defendant from erroneous conviction
    but instead protects some other interest. This is true of the defendant’s
    right to conduct his own defense, which, when exercised, usually increases
    the likelihood of a trial outcome unfavorable to the defendant. . . . That
    right is based on the fundamental legal principle that a defendant must be
    allowed to make his own choices about the proper way to protect his own
    liberty. . . . Because harm is irrelevant to the basis underlying the right,
    the Court has deemed a violation of that right structural error. . . .
    ‘‘Second, an error has been deemed structural if the effects of the error
    are simply too hard to measure. For example, when a defendant is denied
    the right to select his or her own attorney, the precise effect of the violation
    cannot be ascertained. . . . Because the government will, as a result, find
    it almost impossible to show that the error was harmless beyond a reasonable
    doubt . . . the efficiency costs of letting the government try to make the
    showing are unjustified.
    ‘‘Third, an error has been deemed structural if the error always results
    in fundamental unfairness. For example, if an indigent defendant is denied
    an attorney or if the judge fails to give a reasonable-doubt instruction, the
    resulting trial is always a fundamentally unfair one. See Gideon v. Wain-
    wright, 
    372 U.S. 335
    , [343–45], 
    83 S. Ct. 792
    , 
    9 L. Ed. 2d 799
    (1963) (right
    to an attorney); Sullivan v. Louisiana, 
    508 U.S. 275
    , 279, 
    113 S. Ct. 2078
    ,
    
    124 L. Ed. 2d 182
    (1993) (right to a reasonable-doubt instruction). It therefore
    would be futile for the government to try to show harmlessness.’’ (Citations

    General Statutes § 54-47a (b) provides in relevant part: ‘‘No such witness
    may be prosecuted or subjected to any penalty or forfeiture for or on account
    of any transaction, matter or thing concerning which he is compelled to
    testify or produce evidence, and no testimony or evidence so compelled, and
    no evidence discovered as a result of or otherwise derived from testimony
    or evidence so compelled, may be used as evidence against him in any
    proceeding, except that no witness shall be immune from prosecution for
    perjury or contempt committed while giving such testimony or producing
    such evidence . . . .’’ (Emphasis added.)
    8
    The fact that Harris did not testify under the penalty of perjury, despite
    the oath that he took in front of the jury, may also implicate the defendant’s
    constitutional right to confront witnesses against him, as provided under
    the sixth amendment. See Maryland v. Craig, 
    497 U.S. 836
    , 845–46, 110 S.
    Ct. 3157, 
    111 L. Ed. 2d 666
    (1990) (‘‘The central concern of the Confrontation
    Clause is to ensure the reliability of the evidence against a criminal defendant
    by subjecting it to rigorous testing in the context of an adversary proceeding
    before the trier of fact. . . . [T]he right guaranteed by the Confrontation
    Clause includes not only a personal examination . . . but also . . . insures
    that the witness will give his statements under oath—thus impressing him
    with the seriousness of the matter and guarding against the lie by the
    possibility of a penalty for perjury . . . .’’ [Citations omitted; internal quota-
    tion marks omitted.]).

    Because I conclude that the trial court committed structural error by
    permitting the state to grant Harris immunity from any perjury prosecution
    related to his testimony, I need not reach the issue of whether this court
    should also exercise its supervisory authority to reverse the defendant’s
    conviction and to remand the case for a new trial, or instead to set rules
    only for the future.
