    STATE OF CONNECTICUT v. ENRIQUE AYALA
    (SC 19466)
    Rogers, C. J., and Palmer, Eveleigh, McDonald, Espinosa and Robinson, Js.*
    Argued September 15, 2016—officially released February 7, 2017
    Mitchell S. Brody, senior assistant state’s attorney,
    with whom, on the brief, were Michael Dearington,
    former state’s attorney, and Seth R. Garbarsky, assis-
    tant state’s attorney, for the appellant (state).
    Katherine C. Essington, for the appellee (defendant).
    Opinion
    McDONALD, J. We consider in this appeal whether
    allowing the state to amend an information after the
    commencement of trial to charge additional offenses
    without good cause constitutes per se reversible error.
    The state appeals, upon our grant of certification, from
    the judgment of the Appellate Court reversing the judg-
    ment of conviction of the defendant, Enrique Ayala, of
    three counts of interfering with an officer in violation
    of General Statutes § 53a-167a. See State v. Ayala, 
    154 Conn. App. 631
    , 656, 
    106 A.3d 941
    (2015). The state
    contends that, in the absence of prejudice, the trial
    court’s decision to allow a midtrial amendment charging
    additional offenses was neither an abuse of discretion
    nor reversible error. We conclude that, although the
    trial court abused its discretion in allowing the state to
    amend the information without good cause to charge
    additional offenses, that impropriety would not require
    reversal of the defendant’s conviction on the amended
    charges in the absence of prejudice. We further con-
    clude, however, that the Appellate Court’s judgment
    must be affirmed because the improper amendment
    was not harmless beyond a reasonable doubt under the
    circumstances of this case.
    At trial, the state proffered testimony from three Meri-
    den police officers and an emergency medical techni-
    cian regarding the defendant’s conduct at a motor
    vehicle stop and later in a holding cell at a police station
    that gave rise to the charges in this case.1 On the basis
    of that evidence, the jury reasonably could have found
    the following facts.
    On February 9, 2012, the defendant’s girlfriend,
    Michelle Sofianos, drove the defendant home in a motor
    vehicle registered and insured in his name. Shortly after
    the defendant exited the vehicle, Sofianos made an ille-
    gal U-turn near the intersection of Orange and Hanover
    Streets in Meriden, which prompted Officer David Buck
    to initiate a traffic stop. Officer Margaret Smusz, who
    had been dispatched to the scene, arrived shortly there-
    after and approached the passenger’s side of the
    vehicle.
    The defendant observed the stop and came back
    toward the vehicle. Smusz warned Buck that a male
    was approaching him from behind. Using profanity, the
    defendant asked why Sofianos was being detained.
    Buck then ordered the defendant to stand on the side-
    walk, away from the vehicle. The defendant complied
    but continued to yell and swear at the officers, and
    appeared to be intoxicated.
    After Sofianos identified the defendant for the offi-
    cers, facts came to light that caused the officers to
    become concerned that he might be carrying a weapon.
    Smusz testified that she recognized the defendant’s
    name as the name of the person she had previously
    arrested for a narcotics violation, and that in the course
    of that arrest, the police found an unlicensed handgun
    in his vehicle. In addition, the officers observed that
    the defendant was wearing a leather vest bearing the
    insignia of a motorcycle club. Buck testified that during
    his police training he learned that members of outlaw
    motorcycle clubs often carried weapons. Consequently,
    Buck radioed for additional assistance and Officer
    Shane Phillips was dispatched to the scene.
    Once Phillips arrived, he and Smusz approached the
    defendant and asked if he had any weapons on him, to
    which the defendant replied that he did not. Notwith-
    standing the defendant’s answer, Phillips and Smusz
    instructed the defendant that they were going to pat
    him down for weapons. When Phillips started patting
    him down, the defendant ‘‘tensed up’’ and tried to ‘‘pull
    away.’’ Phillips and Smusz immediately grabbed the
    defendant’s arms and placed him on the hood of the
    defendant’s vehicle. The defendant attempted to raise
    himself off the vehicle, but the officers pushed his head
    down, causing the defendant to bite his lip, drawing
    blood. Phillips handcuffed the defendant, arrested him
    for interfering, and conducted a pat-down search that
    did not yield a weapon. Phillips thereafter escorted the
    defendant to the police station on West Main Street.
    At the police station, the defendant exited the cruiser
    and walked inside without incident. Upon entering the
    holding cell, Buck, Smusz, Phillips, and the desk ser-
    geant made the defendant face the corner of the cell,
    with his legs spread apart, so they could remove his
    outer layers of clothing in accordance with standard
    procedures. The defendant was compliant until the offi-
    cers tried to remove his motorcycle club vest. At that
    point, the defendant called the officers pigs and uttered
    profanity, stating: ‘‘[Y]ou’re not taking my . . . colors.’’
    Nevertheless, Phillips began to take off the defendant’s
    vest after Smusz removed his handcuffs. With his hands
    still behind his back, the defendant ‘‘tensed up,’’
    clenched down on the vest to prevent its removal, and
    brought his left arm forward. The officers perceived his
    actions as a threat and immediately drove the defendant
    forward into the concrete wall in the corner of the cell.
    In order to resecure the handcuffs, Buck, Smusz,
    Phillips and the desk sergeant forced the defendant to
    the ground, facedown, and instructed him to place his
    arms behind his back. The defendant locked his arms
    under his chest and struggled with the officers until
    Buck used a Taser device to stun him, after which
    the officers were able to remove the vest and put the
    handcuffs back on. The officers summoned medical
    assistance after noticing that the defendant had sus-
    tained an injury to his forehead. The defendant resisted
    efforts by Smusz and Phillips to position him so that
    medical personnel could attend to him. Smusz testified
    that, in the course of thrashing his legs backward
    toward the officers, the defendant kicked her in the
    thigh. Afterward, the defendant refused to cooperate
    with the booking process or answer questions for a
    suicide evaluation. As a result, the officers cut off his
    clothing, gave him a paper suit to wear, and placed him
    in a cell designated for suicide watch.
    The defendant attempted to present a starkly differ-
    ent version of the events in his cross-examination of
    the state’s witnesses and through his own testimony
    and that of Sofianos. The defendant and Sofianos testi-
    fied that the defendant was neither belligerent nor
    intoxicated that evening; rather, the defendant wanted
    to help Sofianos locate the vehicle’s registration and
    insurance information and he immediately complied
    with Buck’s order to stand on the sidewalk. The defen-
    dant testified that once Smusz and Phillips arrived, they
    walked straight toward him and put him in handcuffs.
    Sofianos and the defendant testified that the defendant
    was not resisting during the ensuing patdown, but Phil-
    lips nevertheless slammed his face into the hood of the
    vehicle. According to the defendant, Phillips said that
    he should have known better than to approach a police
    officer from behind while wearing a motorcycle club
    vest.
    The defendant maintained that he was compliant at
    the police station because he wanted to get the booking
    process over with in order to make bond that night. He
    denied calling the officers ‘‘pigs’’ or swearing at them.
    He claimed that he did not try to prevent the removal
    of his vest; rather, the combination of Phillips and Buck
    pulling him in opposite directions and Phillips kicking
    his feet into a wide stance caused him to lose his balance
    and forced him to move his hands forward to catch
    himself. The defendant denied struggling with the offi-
    cers while he was on the ground, claiming that it was
    not possible for him to put his hands behind his back
    with the officers on top of him. Although the defendant
    admitted that he had refused medical treatment and
    asked to be left alone, he denied kicking Smusz.
    In addition to these facts, the following procedural
    history gives rise to the issues before us on appeal. On
    the day that jury selection was due to commence, the
    state filed a long form information charging the defen-
    dant with one count of assault of a peace officer
    (Smusz) in violation of General Statutes § 53a-167c and
    three counts of interfering with an officer (Buck, Smusz,
    and Phillips) in violation of § 53a-167a. All of the
    offenses were alleged to have occurred at the intersec-
    tion of Hanover and Orange Streets, the site of the
    motor vehicle stop.
    On the third day of voir dire, the state requested
    permission to amend the information to change the
    location of the assault charge from the site of the motor
    vehicle stop to West Main Street, the location of the
    Meriden Police Department. The trial court granted per-
    mission for the amendment, noting that it was not a
    ‘‘material change’’ and that the location of the alleged
    assault was ‘‘clear from the police report, so as not
    to be surpris[ing] or . . . prejudic[ial].’’ The defendant
    conceded that he was aware that the police station was
    the site of the alleged assault and did not object to the
    amendment. The trial court asked the state whether
    the location for the interference charges—Hanover and
    Orange Streets—was still correct, to which the prosecu-
    tor responded: ‘‘That’s still accurate.’’ The prosecutor
    reiterated the following morning that the location of the
    three counts of interference ‘‘remain[ed] unchanged.’’
    On the third day of evidence, just before direct exami-
    nation of the last witness for the state recommenced,
    defense counsel filed a request for a jury instruction
    explaining that the jury was not to consider ‘‘what inter-
    ference may or may not have occurred in connection
    with the charge of assault on [Smusz] at the Meriden
    Police Department.’’ Counsel expressed a concern that
    the ‘‘testimony about the defendant’s cooperation or
    lack thereof while detained at the Meriden Police
    Department’’ might confuse the jury because the only
    charged conduct at the police station was the alleged
    assault. The state made no objection to this request on
    the record.
    After the state completed its case-in-chief and
    defense counsel completed direct examination of the
    defendant, the prosecutor noted for the record that a
    charging conference had been held off the record, at
    which time the trial court granted the state permission
    to allege that the defendant’s interference with the three
    officers constituted ‘‘a continuing course of conduct’’
    during his entire encounter with them. The trial court
    noted that, although it initially had been reluctant to
    permit the state to pursue this theory, its review of
    the case law persuaded it that the state could assert a
    continuing course of conduct over the duration of the
    defendant’s contact with law enforcement as a basis of
    an interference charge.
    Before closing arguments, the state filed a second
    amended information and an amended request to
    charge. The second amended information maintained
    the three counts of interference but alleged in each
    count that the interference against each officer had
    occurred at the intersection of Hanover and Orange
    Streets and at the Meriden Police Department. The
    amended unanimity charge given by the trial court to
    the jury was substantially identical to that submitted
    by the state, and provided: ‘‘The state has alleged that
    the defendant has committed the offenses of interfering
    with an officer throughout the course of his contacts
    with police officers on February 9, 2012, both at the
    intersection of Hanover and Orange Streets and at the
    Meriden Police Department. You may find the defen-
    dant guilty of the offenses only if you all unanimously
    agree on when and where the defendant committed the
    offenses. This means you may not find the defendant
    guilty unless you all agree that the state has proved
    beyond a reasonable doubt that the defendant commit-
    ted the . . . offense or offenses at the intersection of
    Hanover and Orange Streets, or you all agree that the
    state has proved beyond a reasonable doubt that the
    defendant committed the offense or offenses at the
    Meriden Police Department.’’
    Defense counsel stated for the record that the second
    amended information was ‘‘an unfair surprise coming
    at the end of evidence or close to the end of evidence,’’
    and ‘‘that it may have been possible to argue differently’’
    based on the new interference charges.2 The trial court
    rejected the defendant’s contention, concluding that,
    on the basis of the police report and the testimony
    elicited at trial, ‘‘there was no unfair surprise and . . .
    counsel clearly cross-examined with an eye toward
    being able to argue when there was interfering and
    when there was not interfering, both at the police
    department and . . . at the motor vehicle stop at Han-
    over and Orange Streets.’’ The court thereafter
    instructed the jury in accordance with the state’s una-
    nimity charge. No interrogatories were submitted to the
    jury to ascertain its verdict with respect to the site of
    the alleged interferences.
    The jury acquitted the defendant of the assault charge
    but found him guilty of the three counts of interfering
    with an officer. The court rendered judgment in accor-
    dance with the verdict and imposed an effective sen-
    tence of two years imprisonment, consecutive to a
    sentence that the defendant was serving in an unre-
    lated case.
    The defendant appealed from the judgment of convic-
    tion to the Appellate Court. The defendant’s principal
    claim on appeal was that the trial court had abused its
    discretion by permitting the state to amend the informa-
    tion in violation of his sixth amendment rights under
    the federal constitution3 and his due process right to
    proper notice of the charges against him. State v. 
    Ayala, supra
    , 
    154 Conn. App. 643
    . Although the defendant con-
    tended that he had been prejudiced by the late amend-
    ment, the Appellate Court did not reach that issue
    because it determined that the state’s failure to meet the
    first two of the three requirements for an amendment of
    the information after the commencement of trial under
    Practice Book § 36-184 rendered the trial court’s deci-
    sion an abuse of discretion that required reversal of the
    judgment of conviction. 
    Id., 644 n.17,
    655–56.
    The Appellate Court first concluded that the record
    reflected neither a finding by the trial court that there
    was good cause for the amendment after the com-
    mencement of trial nor any basis to support such a
    finding. 
    Id., 644, 647–48.
    The Appellate Court observed
    that ‘‘the [trial] court made no finding that there was
    new evidence or evidence that the state had not antici-
    pated to warrant amending the information at that
    time.’’ 
    Id., 647. The
    Appellate Court rejected the state’s
    argument that Practice Book § 36-18 permits a trial
    court to allow an amendment even in the absence of
    good cause. 
    Id., 648–49. The
    Appellate Court further concluded that, even if
    the record established good cause, which it did not, the
    trial court abused its discretion in allowing the second
    amendment because it alleged additional offenses,
    thereby violating another limitation under Practice
    Book § 36-18. 
    Id., 650. The
    Appellate Court observed:
    ‘‘There are two types of amendments that can result in
    the charging of a different or additional offense. One
    type of amendment produces what is commonly
    described as a factually different offense in that it alters
    the facts alleged, but continues to allege a violation of
    the same substantive crime as the original pleading; the
    other type charges a legally separate offense. . . . The
    second amended long form information constitutes the
    addition of a crime on factually distinct grounds. In
    other words, the defendant was alleged to have inter-
    fered with the police officers, the substantive crime,
    at two separate locations, i.e., two factually different
    crimes.’’ (Citations omitted.) 
    Id., 652. The
    Appellate
    Court reasoned that, ‘‘[n]otwithstanding the state’s
    attempt to conflate the traffic stop and police station
    conduct into one event, the evidence demonstrates that
    the charges of interference were based on two separate,
    distinct acts of alleged interference occurring at sepa-
    rate places, and separated by the transporting of the
    defendant from one location to another. See United
    States v. Chappell, 
    704 F.3d 551
    , 552 (8th Cir. 2013)
    (criminal offense is distinct crime when it occurs in
    different location and at different time).’’ State v. 
    Ayala, supra
    , 
    154 Conn. App. 655
    . The Appellate Court ques-
    tioned whether the state’s continuing course of conduct
    theory was even cognizable in this context, but
    observed that such a theory was in any event inconsis-
    tent with the unanimity charge given to the jury. 
    Id., 643 n.13.
    On the basis of the violations of § 36-18 that
    it identified, the Appellate Court reversed the judgment
    of conviction and remanded the case for a new trial.
    
    Id., 656. We
    thereafter granted the state’s petition for certifica-
    tion to appeal, limited to the following issue: ‘‘Did the
    Appellate Court properly reverse the defendant’s con-
    viction based upon its determination that the trial court
    had abused its discretion by permitting the state to
    amend its information after the start of the trial?’’ State
    v. Ayala, 
    316 Conn. 908
    , 
    111 A.3d 883
    (2015). The state’s
    principal contention is that a trial court cannot abuse its
    discretion in allowing an amendment to the information
    unless the amendment causes prejudice to the defen-
    dant’s substantive right to notice of the charges against
    which he must defend, which the trial court concluded
    did not exist in this case. The state further argues that,
    even if a trial court could abuse its discretion in allowing
    an amendment without good cause to charge additional
    offenses, the defendant would not be entitled to reversal
    of his conviction on the new charges without showing
    that the error was harmful. The state contends that the
    amendment did not impair the defendant’s ability to
    present his defense and therefore he is not entitled to
    a new trial.
    We agree with the state that it is important to distin-
    guish between the trial court’s obligations and the right
    to relief from trial court error, a distinction that has
    not always been made clear in appellate case law
    addressing Practice Book § 36-18. We disagree with the
    state, however, that the defendant is not entitled to a
    new trial. We conclude that reversal of the judgment
    was proper, although for slightly different reasons than
    those relied on by the Appellate Court.
    I
    We begin with the question of whether the Appellate
    Court properly determined that the trial court abused
    its discretion in allowing the state to amend the informa-
    tion. We underscore that the state does not challenge
    the Appellate Court’s conclusions that the state lacked
    good cause for the amendment or that the amendment
    resulted in the inclusion of additional offenses. Instead,
    the state contends that, unless the amendment caused
    prejudice to the defendant, such factors do not result
    in an abuse of discretion in granting the amendment.
    We disagree.5
    ‘‘Before the commencement of trial, a prosecutor has
    broad authority to amend an information under Practice
    Book § [36-17]. Once the trial has started, however, the
    prosecutor is constrained by the provisions of Practice
    Book § [36-18].’’ State v. Tanzella, 
    226 Conn. 601
    , 607,
    
    628 A.2d 973
    (1993). For purposes of Practice Book
    § 36-18, a trial begins with the commencement of voir
    dire. 
    Id., 608. Practice
    Book § 36-18 provides in relevant part: ‘‘After
    commencement of the trial for good cause shown, the
    judicial authority may permit the prosecuting authority
    to amend the information at any time before a verdict
    or finding if no additional or different offense is charged
    and no substantive rights of the defendant would be
    prejudiced. . . .’’ It is well settled that the state bears
    the burden of demonstrating that it has complied with
    the requirements of § 36-18 in seeking permission to
    amend the information. See State v. 
    Tanzella, supra
    ,
    
    226 Conn. 614
    (‘‘[l]ike any other party petitioning the
    court, the state must demonstrate the basis for its
    request [to amend the information]’’). A trial court’s
    decision to allow the state to amend the information
    is reviewed for an abuse of discretion. See State v.
    Ramos, 
    176 Conn. 275
    , 276, 
    407 A.2d 952
    (1978).
    On its face, Practice Book § 36-18 states three predi-
    cates that the state must meet to obtain permission to
    amend the information: (1) good cause; (2) no addi-
    tional or different offense is charged; and (3) no preju-
    dice to the defendant’s substantive rights. State v.
    Petitpas, 
    299 Conn. 99
    , 104 n.6, 
    6 A.3d 1159
    (2010);
    State v. 
    Tanzella, supra
    , 
    226 Conn. 614
    .
    These requirements serve two purposes. First, they
    encourage the state to prepare its case carefully. State
    v. 
    Tanzella, supra
    , 
    226 Conn. 614
    –15. Good cause in
    this context assumes some circumstance that the state
    could not have reasonably anticipated or safeguarded
    against before trial commenced. See State v. Victor C.,
    
    145 Conn. App. 54
    , 65, 
    75 A.3d 48
    (‘‘To comply with the
    first prong of the test and meet its burden of showing
    good cause . . . the state must provide more than a
    bare assertion that it is merely conforming the charge
    to the evidence. . . . The state must demonstrate why
    the information necessitated substitution.’’ [Citation
    omitted; emphasis in original; internal quotation marks
    omitted.]), cert. denied, 
    310 Conn. 933
    , 
    78 A.3d 859
    (2013). Second, and more fundamentally, the require-
    ments ensure that the defendant has adequate notice
    of the charges against which he must defend. State v.
    
    Tanzella, supra
    , 608; State v. Jacobowitz, 
    182 Conn. 585
    , 590, 
    438 A.2d 792
    (1981), overruled in part on other
    grounds by State v. Welch, 
    224 Conn. 1
    , 4, 
    615 A.2d 505
    (1992). As such, Practice Book § 36-18 is not only a
    rule of procedure, but a prophylactic rule designed to
    protect a criminal defendant’s ‘‘constitutional right to
    be informed of the nature and cause of the charges
    against him with sufficient precision to enable him to
    meet them at trial.’’ (Internal quotation marks omitted.)
    State v. Bergin, 
    214 Conn. 657
    , 674, 
    574 A.2d 164
    (1990);
    see also State v. Morrill, 
    197 Conn. 507
    , 551, 
    498 A.2d 76
    (1985) (‘‘[w]hen the state’s pleadings have informed
    the defendant of the charge against him with sufficient
    precision to enable him to prepare his defense and to
    avoid prejudicial surprise, and were definite enough to
    enable him to plead his acquittal or conviction in bar
    of any future prosecution for the same offense, they
    have performed their constitutional duty’’ [internal quo-
    tation marks omitted]).
    In light of the dual purposes served by the require-
    ments of Practice Book § 36-18, we decline to interpret
    its provisions in a way that would disregard either the
    good cause requirement or the additional or different
    offense prohibition. We are bound to give effect to each
    requirement of § 36-18. See generally State v. Strick-
    land, 
    243 Conn. 339
    , 347–48, 
    703 A.2d 109
    (1997) (‘‘our
    rules of practice should be construed harmoniously and
    not in a way that would render one provision superflu-
    ous as a result of the existence of another’’). To hold,
    as the state urges, that prejudice is the only inquiry in
    determining whether a violation of § 36-18 has occurred
    would effectively read the good cause requirement, the
    additional or different offense prohibition, and the con-
    junctive ‘‘and’’ preceding the element of prejudice out
    of the rule. If that was the intent of the drafters, there
    would have been no point to including the good cause
    shown and no additional or different offense charged
    language; ‘‘it would have been necessary to provide
    only that amendment would not be allowed if substan-
    tial rights of the defendant are not prejudiced.’’ (Internal
    quotation marks omitted.) United States v. Personal
    Finance Co. of New York, 
    13 F.R.D. 306
    , 311 (S.D.N.Y.
    1952); accord Simon v. Government of the Virgin
    Islands, 
    47 V.I. 3
    , 8 (2002), appeal dismissed in part
    and remanded in part on other grounds, 
    116 F. Supp. 3d
    529 (D.V.I. 2015).
    Despite this court’s unambiguous statement in State
    v. 
    Tanzella, supra
    , 
    226 Conn. 614
    , that there are three
    requirements that the prosecution must satisfy, the
    state has seized upon language in that case that it asserts
    effectively did away with the first two components of
    Practice Book § 36-18. The state first argues that satis-
    faction of the good cause requirement is not a necessary
    predicate to allowing an amendment to the information
    because this court observed in Tanzella that § 36-18
    ‘‘permits amendments to an information after trial has
    commenced provided ‘no additional or different
    offense is charged and no substantive rights of the
    defendant would be prejudiced.’ ’’ (Emphasis added.)
    
    Id., 607–608. Some
    Appellate Court decisions have since
    stated that the trial court’s discretion pursuant to § 36-
    18 is ‘‘limited only by’’ the latter two requirements of
    the provision. See, e.g., State v. Adams, 
    38 Conn. App. 643
    , 649, 
    662 A.2d 1327
    , cert. denied, 
    235 Conn. 908
    ,
    
    665 A.2d 902
    (1995). Our exclusive focus on those two
    requirements in Tanzella, however, is readily explained
    by the fact that the defendant in that case had effectively
    conceded good cause. See State v. 
    Tanzella, supra
    , 608
    n.8. Indeed, numerous Appellate Court decisions have
    properly recognized that the prosecution must establish
    good cause at trial. See, e.g., State v. Victor 
    C., supra
    ,
    
    145 Conn. App. 65
    –66 (assessing whether good cause
    was shown); State v. Jordan, 
    132 Conn. App. 817
    , 824–
    25, 
    33 A.3d 307
    (same), cert. denied, 
    304 Conn. 909
    , 
    39 A.3d 1119
    (2012); State v. Grant, 
    83 Conn. App. 90
    ,
    93–95, 98, 
    848 A.2d 549
    (same), cert. denied, 
    270 Conn. 913
    , 
    853 A.2d 529
    (2004); State v. Wilson F., 77 Conn.
    App. 405, 413, 
    823 A.2d 406
    (same), cert. denied, 
    265 Conn. 905
    , 
    831 A.2d 254
    (2003).
    The state similarly takes out of context another state-
    ment in Tanzella to support its contention that an abuse
    of discretion arises only from an amendment that
    impairs the defendant’s substantive rights. In that case,
    we observed: ‘‘For purposes of [Practice Book § 36-18],
    the decisive question is whether the defendant was
    informed of the charges with sufficient precision to be
    able to prepare an adequate defense.’’ State v. 
    Tanzella, supra
    , 
    226 Conn. 608
    . That statement was made, how-
    ever, in the context of explaining why we declined to
    use a comparison of the elements of each of the offenses
    to determine whether the amended charges constituted
    additional or different offenses. See 
    id. Accordingly, in
    the present case, the trial court
    abused its discretion by allowing the state to amend the
    information in the absence of a showing, and finding, of
    good cause. As the Appellate Court properly observed,
    the trial court failed to make any finding regarding good
    cause. See State v. 
    Ayala, supra
    , 
    154 Conn. App. 644
    ,
    647–48. Indeed, the failure to exercise discretion is an
    abuse in and of itself. See State v. Martin, 
    201 Conn. 74
    ,
    88, 
    513 A.2d 116
    (1986) (‘‘[w]here . . . the trial court is
    properly called upon to exercise its discretion, its fail-
    ure to do so is error’’). Moreover, the record reveals
    no basis upon which the trial court could have made
    a finding of good cause for the amendment,6 especially
    in light of the prosecutor’s repeated assurances, after
    amending the information to change the location of the
    assault, that the location of the interference was ‘‘still
    accurate’’ and ‘‘remain[ed] unchanged.’’7 In addition,
    the state conceded at oral argument before this court
    that the instances of interference at the intersection of
    Hanover and Orange Streets and at the police station
    constituted ‘‘two distinct acts or transactions separated
    by time and location’’; State v. 
    Ayala, supra
    , 655; see
    also State v. Tweedy, 
    219 Conn. 489
    , 494, 
    594 A.2d 906
    (1991); the basis for the Appellate Court’s conclusion
    that the amendment resulted in additional offenses.8 As
    such, the Appellate Court properly concluded that the
    trial court abused its discretion in allowing the
    amendment.
    II
    The Appellate Court concluded that the trial court’s
    abuse of discretion required reversal of the judgment.
    Indeed, the court concluded that it was unnecessary to
    reach the defendant’s claim that he was prejudiced by
    the amendment. As such, the Appellate Court effectively
    determined that a violation of the good cause require-
    ment and the additional or different offense prohibition
    is per se reversible error and, consequently, structural
    error. Although we disagree with that legal conclusion,
    we conclude that the Appellate Court’s judgment should
    be affirmed on the ground that the state has failed to
    meet its burden of proving that the amendment was
    harmless beyond a reasonable doubt.
    A
    It is well settled that ‘‘[n]ot every deviation from the
    specific requirements of a Practice Book rule necessi-
    tates reversal.’’ State v. Suggs, 
    194 Conn. 223
    , 226–27,
    
    478 A.2d 1008
    (1984). ‘‘Ordinarily, our courts apply a
    harmless error analysis in determining whether a viola-
    tion of a rule of practice amounts to reversible error.’’
    State v. 
    Pare, supra
    , 
    253 Conn. 636
    . To the extent that
    a failure to comply with a rule of practice rises to the
    level of a constitutional violation, ‘‘[t]he United States
    Supreme Court has recognized that ‘most constitutional
    errors can be harmless.’ ’’ State v. Anderson, 
    255 Conn. 425
    , 444, 
    773 A.2d 287
    (2001), quoting Neder v. United
    States, 
    527 U.S. 1
    , 8, 
    119 S. Ct. 1827
    , 
    144 L. Ed. 2d 35
    (1999).
    ‘‘The harmless error doctrine recognizes the principle
    that the central purpose of a criminal trial is to decide
    the factual question of the defendant’s guilt or inno-
    cence . . . and promotes public respect for the crimi-
    nal process by focusing on the underlying fairness of
    the trial rather than on the virtually inevitable presence
    of immaterial error. . . . Accordingly, we forgo harm-
    less error analysis only in rare instances involving a
    structural defect of constitutional magnitude.’’ (Empha-
    sis in original; internal quotation marks omitted.) State
    v. Artis, 
    314 Conn. 131
    , 149–50, 
    101 A.3d 915
    (2014);
    see also Rose v. Clark, 
    478 U.S. 570
    , 579, 
    106 S. Ct. 3101
    ,
    
    92 L. Ed. 2d 460
    (1986) (‘‘if the defendant had counsel
    and was tried by an impartial adjudicator, there is a
    strong presumption that any other errors that may have
    occurred are subject to harmless-error analysis’’).
    ‘‘Structural defect cases defy analysis by harmless
    error standards because the ‘entire conduct of the trial,
    from beginning to end, is obviously affected . . . .’ Ari-
    zona v. Fulminante, [
    499 U.S. 279
    , 309–10, 
    111 S. Ct. 1246
    , 
    113 L. Ed. 2d 302
    (1991)]. These cases ‘contain a
    defect affecting the framework within which the trial
    proceeds, rather than simply an error in the trial process
    itself. [Id., 310]. Such errors infect the entire trial pro-
    cess . . . and necessarily render a trial fundamentally
    unfair . . . . Put another way, these errors deprive
    defendants of basic protections without which a crimi-
    nal trial cannot reliably serve its function as a vehicle
    for determination of guilt or innocence . . . and no
    criminal punishment may be regarded as fundamentally
    fair.’ . . . Neder v. United 
    States, supra
    , 
    527 U.S. 8
    –9.’’
    (Citations omitted.) State v. 
    Anderson, supra
    , 
    255 Conn. 445
    .
    With these principles in mind, we turn to the rule of
    practice at issue. As reflected in our discussion in part
    I of this opinion, the good cause requirement in Practice
    Book § 36-18, standing alone, is not intended to vindi-
    cate any constitutional right; rather, its purpose is to
    encourage the state to diligently prepare its case. See
    State v. 
    Tanzella, supra
    , 
    226 Conn. 614
    –15. As such,
    consistent with our harmless error jurisprudence for
    nonconstitutional claims, our appellate case law has
    never treated a lack of good cause, in and of itself, as
    reversible error. See, e.g., State v. Carlos E., 158 Conn.
    App. 646, 653 n.4, 
    120 A.3d 1239
    (considering whether
    defendant suffered prejudice as result of amendment
    despite state’s failure to make any attempt to articulate
    good cause and trial court’s failure to make explicit
    finding on good cause), cert. denied, 
    319 Conn. 909
    ,
    
    125 A.3d 199
    (2015); see also State v. 
    Petitpas, supra
    , 
    299 Conn. 101
    , 103–104 (affirming judgment of conviction
    despite defendant’s argument that state failed to show
    good cause for amending information because court
    was ‘‘unable to perceive how the defendant could have
    been prejudiced by an amendment that deprived the
    state of a means of proving the offense’’). Thus, a trial
    court’s abuse of discretion in allowing the state to
    amend the information midtrial without a showing of
    good cause, standing alone, would fall squarely within
    our jurisprudence requiring the defendant to show that
    the nonconstitutional error was harmful to reverse the
    judgment of conviction.9 See State v. Payne, 
    303 Conn. 538
    , 553, 
    34 A.3d 370
    (2012) (‘‘[w]hen an error is not
    of constitutional magnitude, the defendant bears the
    burden of demonstrating that the error was harmful’’).
    Whether there has been an abuse of discretion arising
    from a violation of the additional or different offense
    prohibition set forth in Practice Book § 36-18 presents
    a more difficult question. In our seminal case on this
    issue, State v. 
    Jacobowitz, supra
    , 
    182 Conn. 590
    –93, this
    court reversed the defendant’s judgment of conviction
    on the ground that the trial court improperly allowed
    the state to amend the information to add a different
    offense after it concluded its case-in-chief, without tak-
    ing into consideration whether the amendment caused
    prejudice to the defendant. Some Appellate Court deci-
    sions rendered shortly after Jacobowitz followed this
    holding and concluded that an amendment of an infor-
    mation in violation of the additional or different offense
    prohibition made during presentation of the state’s
    case-in-chief is, in and of itself, reversible error with
    respect to the new charge. See, e.g., State v. Cole, 
    8 Conn. App. 545
    , 552, 
    513 A.2d 752
    (1986); State v. Kitt,
    
    8 Conn. App. 478
    , 488–89, 
    513 A.2d 731
    , cert. denied,
    
    202 Conn. 801
    , 
    518 A.2d 648
    (1986).
    Conversely, the most recent Appellate Court decision
    on this issue employed harmless error review after con-
    cluding that when the state amended the information at
    the close of its case-in-chief by substituting the original
    charge of burglary in the first degree with burglary
    in the second degree, that substitution constituted a
    different offense. State v. Ramirez, 
    94 Conn. App. 812
    ,
    816–17, 
    894 A.2d 1032
    , cert. denied, 
    278 Conn. 915
    , 
    899 A.2d 621
    (2006). The court observed that ‘‘the improper
    amendment of the information implicates the defen-
    dant’s constitutional right to fair notice of the charges
    against him . . . [and, consequently] the state must
    prove such error was harmless beyond a reasonable
    doubt.’’ (Internal quotation marks omitted.) 
    Id., 819. The
    court determined that the error in that case was
    harmless beyond a reasonable doubt because ‘‘[t]he
    defense theory [of mistaken identity] . . . was not
    related to the elements of the crime as originally
    charged or as amended. As a result, the amendment
    did not prejudice the defense because the effect of
    the amendment was logically distinct from the defense
    asserted.’’ 
    Id., 820. We
    conclude that Jacobowitz should be overruled
    insofar as it suggests that any amendment to an informa-
    tion violating the additional or different offense prohibi-
    tion results in per se reversible error. When Jacobowitz
    was decided, our harmless error jurisprudence, particu-
    larly with respect to constitutional error, was not yet
    well developed. Compare State v. Cohane, 
    193 Conn. 474
    , 485, 
    479 A.2d 763
    (‘‘[i]f error touches a less basic
    constitutional right, we sometimes apply the harmless
    error exception, but only sparingly, in a few, discrete
    circumstances’’ [internal quotation marks omitted]),
    cert. denied, 
    469 U.S. 990
    , 
    105 S. Ct. 397
    , 
    83 L. Ed. 2d 331
    (1984), with State v. 
    Anderson, supra
    , 
    255 Conn. 444
    (acknowledging United States Supreme Court’s rec-
    ognition in its recent opinion, Neder v. United 
    States, supra
    , 
    527 U.S. 8
    , that ‘‘most constitutional errors can
    be harmless’’ [internal quotation marks omitted]).
    Indeed, it was not until 1997, sixteen years after Jaco-
    bowitz, that the United States Supreme Court empha-
    sized that structural error would be found in a ‘‘very
    limited class of cases . . . .’’ Johnson v. United States,
    
    520 U.S. 461
    , 468, 
    117 S. Ct. 1544
    , 
    137 L. Ed. 2d 718
    (1997).
    We recently overruled a case decided in the same
    year as Jacobowitz because that case rejected harmless
    error analysis in favor of a rule of per se reversibility
    when the state uses unreliable eyewitness identification
    evidence arising from an unnecessarily suggestive
    police procedure. See State v. 
    Artis, supra
    , 
    314 Conn. 145
    –46. In so holding, we recognized that, since that
    case was decided, there had been substantial changes
    in the legal landscape regarding the application of harm-
    less error analysis to constitutional violations. 
    Id., 149. On
    that basis, among others, we agreed with the state
    ‘‘that the introduction of such [unreliable eyewitness]
    testimony in violation of a defendant’s right to due
    process is not one of the rare instances of structural
    error in which the automatic reversal of a conviction is
    warranted.’’ 
    Id., 146. The
    Appellate Court’s more recent
    decision in Ramirez applying harmless error analysis,
    therefore, is more consistent with these developments
    in our jurisprudence.
    It may reasonably be presumed that an amendment
    to an information that charges an additional or different
    offense that is made after trial has commenced gives
    rise to prejudice in the preparation and the presentation
    of the defense. See State v. 
    Cole, supra
    , 
    8 Conn. App. 551
    (discussing effect on voir dire); State v. Caswell,
    
    551 N.W.2d 252
    , 255 (Minn. App. 1996) (discussing effect
    on waiver of jury trial). Indeed, in many cases, prejudice
    may be self-evident. We are not persuaded, however,
    that every amendment made after the commencement
    of trial charging an additional or different offense is
    necessarily prejudicial or is never amenable to such an
    inquiry. See State v. 
    Ramirez, supra
    , 
    94 Conn. App. 816
    –20 (trial court’s abuse of discretion in allowing
    amendment was harmless beyond reasonable doubt
    because defense of mistaken identity was not related
    to elements of either original or substituted charge).
    This court previously has declined to view the violation
    of other substantial constitutional rights as structural
    error, even where the error occurred at the beginning
    of trial and could have had an ongoing effect throughout
    the course of the proceedings. See, e.g., State v. D’An-
    tonio, 
    274 Conn. 658
    , 690–91, 
    877 A.2d 696
    (2005) (trial
    judge’s failure to recuse himself from presiding over
    trial after having participated in unsuccessful plea bar-
    gaining efforts was not plain error requiring reversal);
    State v. Washington, 
    182 Conn. 419
    , 429, 
    438 A.2d 1144
    (1980) (instruction given early in trial permitting jurors
    to discuss case before its submission to them was sub-
    ject to harmless error review). We further observe that,
    although the different/additional offense prohibition is
    also found in the rules or statutes of many other jurisdic-
    tions,10 some of these jurisdictions have declined to
    reverse a conviction on an improper amendment charg-
    ing a different or additional offense unless there is preju-
    dice to the defendant. See Sutton v. United States, 
    140 A.3d 1198
    , 1203 (D.C. App. 2016); Commonwealth v.
    Brown, 
    556 Pa. 131
    , 136, 
    727 A.2d 541
    (1999); see also
    McGahan v. State, 
    606 P.2d 396
    , 397 (Alaska 1980)
    (applying harmless error review to improper amend-
    ment that went beyond form in violation of permis-
    sive statute).11
    We are mindful that other jurisdictions view such
    amendments as inherently prejudicial and, thus, per se
    reversible error.12 See, e.g., Commonwealth v. Souza,
    42 Mass. App. 186, 192–93, 
    675 N.E.2d 432
    , review
    denied, 
    424 Mass. 1107
    , 
    678 N.E.2d 1334
    (1997); State
    v. Jackson, 
    78 Ohio App. 3d 479
    , 483, 
    605 N.E.2d 426
    (1992). Although we can understand why a presumption
    of prejudice logically is warranted, we cannot justify
    an irrebuttable presumption, irrespective of the timing
    of the amendment or the nature of the defense asserted.
    For example, an amendment made just after voir dire
    has commenced to charge an additional or different
    offense would violate Practice Book § 36-18. Yet, in the
    absence of any indication that the amendment rendered
    the defendant ill-equipped to defend against the new
    charge at trial or that he was hampered in his effective
    questioning of the venire panel; see State v. 
    Cole, supra
    ,
    
    8 Conn. App. 551
    ; such an impropriety does not ‘‘neces-
    sarily render [the] criminal trial fundamentally unfair
    or an unreliable vehicle for determining guilt or inno-
    cence.’’ (Emphasis in original.) Neder v. United 
    States, supra
    , 
    527 U.S. 9
    . To the extent that the defendant
    suggests that a bright line rule of reversibility would
    further the public policy of forcing prosecutors to more
    carefully prepare their cases before the commencement
    of trial, we believe that the countervailing policy in
    favor of harmless error review outweighs those noncon-
    stitutional public policy considerations. The underlying
    purpose of harmless error review is to preserve the
    fundamental aim of a criminal trial—the factual deter-
    mination of guilt or innocence—from being subverted
    by the virtually inevitable presence of immaterial error.
    See State v. Perkins, 
    271 Conn. 218
    , 244–45, 
    856 A.2d 917
    (2004).
    In sum, although an amendment that includes an addi-
    tional or different offense will necessarily impact a
    defendant’s constitutional right to notice of the charges
    against him, a defendant is not entitled to a new trial
    if that defect did not impair his ability to prepare for
    trial or present his defense. Accordingly, we decline to
    extend the limited class of cases involving structural
    defects to the error at issue in the present case.
    B
    Finally, we turn to the question of whether the defen-
    dant suffered prejudice to warrant reversal of his judg-
    ment of conviction and a new trial on the interference
    charges. The state contends that it does not bear the
    burden of proving that the trial court’s abuse of discre-
    tion was harmless beyond a reasonable doubt. We dis-
    agree and conclude that, given the nature and timing
    of the amendment, the state cannot meet this burden.
    This court has observed that when the trial court has
    improperly allowed the state to amend an information
    to charge an additional or different offense, the defen-
    dant’s ‘‘constitutional right to fair notice, prior to the
    commencement of trial, of the charges against which he
    must defend himself’’ is infringed. State v.

    (‘‘[w]hen the state amends an information
    after the commencement of trial to add a new count
    that is not a lesser included offense of any count with
    which the defendant has properly been charged, the
    state violates both Practice Book § [36-18] and the
    defendant’s due process right to notice’’); In re Steven
    G., 
    210 Conn. 435
    , 441, 
    556 A.2d 131
    (1989) (‘‘a midtrial
    amendment to an information adding different charges
    in an adult criminal proceeding is violative of due pro-
    cess’’). We are not persuaded by the state’s contention
    that the defendant’s right to fair notice was not impaired
    in the present case because he had actual notice of the
    officers’ version of events reflecting the defendant’s
    resistance during processing at the police station. Sim-
    ply put, there is a significant difference between the
    defendant’s general awareness of the substance of the
    officers’ testimony and his awareness that that testi-
    mony is going to form the basis of charges against him.
    Defense counsel’s request, prior to the amendment at
    issue, to preclude the jury’s use of evidence regarding
    the incident in the holding cell in considering the inter-
    ference at the traffic stop belies the argument that the
    defendant had actual notice that he would be charged
    with interference at the police station.13
    It is well settled that, when certain improprieties are
    of constitutional dimension, the burden falls on the
    state to establish that the impropriety was harmless
    beyond a reasonable doubt. See State v. 
    Cohane, supra
    ,
    
    193 Conn. 484
    –85; accord State v. 
    Ramirez, supra

    , cert. denied, 
    204 Conn. 812
    , 
    528 A.2d 1157
    (1987). The state contends that there was no preju-
    dice to the defendant because, prior to the amendment,
    he presented a complete defense against the additional
    charges when cross-examining the officers and provid-
    ing his own testimony. Specifically, the state contends
    that the defendant attempted to establish that he had
    not interfered, but rather had cooperated with the offi-
    cers at the police station and that any actions of his to
    the contrary were not volitional (i.e., losing his balance).
    The state further contends that the defendant could
    have recalled the officers during the presentation of
    his own case to address any deficiencies in his cross-
    examination and points to his failure to do so or ask
    for a continuance as evidence that the defendant was
    not prejudiced by the amendment. We conclude that,
    even if the defendant had a full and fair opportunity to
    examine the officers in a manner that would support
    a defense against the additional interference charges,
    the state cannot overcome a more fundamental problem
    arising from the timing of the amendment.
    As the defendant properly emphasizes, the state
    amended the information after defense counsel com-
    pleted the defendant’s direct examination and immedi-
    ately before the state commenced its cross-examination
    of him. Accordingly, the amendment occurred after the
    defendant exercised his right to testify or to remain
    silent. It is axiomatic that criminal defendants have a
    fundamental constitutional right to testify on their own
    behalf or to decline to do so. See Rock v. Arkansas,

    ‘‘While the due process clause of the [f]ifth [a]mend-
    ment may be understood to grant the accused the right
    to testify, the if and when of whether the accused will
    testify is primarily a matter of trial strategy to be

    the advice of competent counsel. It is important to
    remember that while defense counsel serves as an advo-
    cate for the client, it is the client who is the master of
    his or her own defense. . . . The wisdom or unwisdom
    of the defendant’s choice does not diminish his right
    to make it.’’ (Emphasis added; internal quotation marks

    In the present case, the defendant’s decision to tes-
    tify, and the scope of that testimony, was necessarily
    informed by the nature of the charges against him. Once
    he exercised his constitutional right to testify, he could
    not reconsider that decision. In the absence of any
    admission to the contrary, the state cannot prove that
    the defendant would have elected to testify even if he
    had timely notice of the additional interference charges.
    Indeed, before the defendant knew that he was being
    charged with interference at the police station, he
    admitted in his direct examination that he had refused
    medical treatment there, an admission that the jury
    might have viewed as bolstering the officers’ testimony
    that the defendant had resisted every effort they had
    undertaken. Moreover, even in the absence of poten-
    tially damaging testimony, the state cannot meet its
    burden because the decision to testify need not be
    objectively reasonable. See State v. 
    Francis, supra
    , 
    317 Conn. 461
    . Accordingly, the state has not satisfied its
    burden of proving beyond a reasonable doubt that the
    improper amendment did not prejudice the defendant’s
    substantive rights.
    The judgment of the Appellate Court is affirmed.
    In this opinion ROGERS, C. J., and PALMER, EVE-
    LEIGH and ROBINSON, Js., concurred.
    * This case was originally argued before a panel of this court consisting
    of Chief Justice Rogers and Justices Palmer, Zarella, Eveleigh, McDonald,
    Espinosa and Robinson. Thereafter, Justice Zarella retired from this court
    and did not participate in the consideration of this decision.
    1
    The state also proffered a videotape of the events at the police station.
    There was no videotape of the motor vehicle stop due to malfunctioning
    equipment in the police cruiser operated by the officer who initiated the stop.
    The defendant challenged on appeal the trial court’s decision precluding him
    from proffering his version of the videotape in slow motion. The Appellate
    Court did not reach this issue, and we need not address the effect of this
    ruling in this certified appeal.
    2
    The defendant has not raised, at trial or on appeal, any objection to the
    form of the second amended information as stating improper duplicitous
    grounds in each interference count. See State v. Cofone, 
    164 Conn. 162
    ,

    The sixth amendment to the United States constitution provides in rele-
    vant part: ‘‘In all criminal prosecutions, the accused shall enjoy the right
    . . . to be informed of the nature and cause of the accusation . . . .’’
    4
    Practice Book § 36-18 provides: ‘‘After commencement of the trial for
    good cause shown, the judicial authority may permit the prosecuting author-
    ity to amend the information at any time before a verdict or finding if no
    additional or different offense is charged and no substantive rights of the
    defendant would be prejudiced. An amendment may charge an additional
    or different offense with the express consent of the defendant.’’
    5
    In light of our conclusion that Practice Book § 36-18 is violated even
    without a showing of prejudice, we need not reach the defendant’s alternative
    ground for affirmance that the trial court abused its discretion in allowing the
    amendment because it improperly concluded that the defendant’s substantial
    rights were not prejudiced by the amendment.
    6
    The dissent asserts, without citing any authority, that good cause exists
    when an amendment conforms the charge to the evidence. As an initial
    matter, the state never argued or represented to the trial court that the
    amendment was necessary to conform the information to the proof. More
    significantly, there is a long line of Appellate Court cases plainly to the
    contrary. See, e.g., State v. Enrique F., 
    146 Conn. App. 820
    , 824, 
    79 A.3d 140
    (2013), cert. denied, 
    311 Conn. 903
    , 
    83 A.3d 350
    (2014); State v. Victor
    
    C., supra
    , 
    145 Conn. App. 65
    ; State v. 
    Jordan, supra
    ,

    ;

    ,

    –95, 98; State v. Wilson 
    F., supra
    ,
    
    77 Conn. App. 413
    .
    7
    To the extent the state summarily asserts in the course of its prejudice
    argument that good cause may have been implicit in the trial court’s conclu-
    sion that defense counsel examined the defendant and the state’s witnesses
    ‘‘with an eye toward’’ defending against interference at the police station,
    that argument is patently without merit. The existence of good cause is not
    examined in relation to the adequacy of the defense asserted, but the neces-
    sity for the amendment.
    8
    Undeterred by the state’s decision not to challenge the Appellate Court’s
    conclusion that the amendment charged additional offenses, and its conces-
    sion of that point at oral argument, the dissent cherry picks facts out of the
    record in order to mount its own challenge to that conclusion, namely, that
    the relatively short time and distance between the two instances of alleged
    interference establish a ‘‘unity’’ in the defendant’s conduct such that it could
    be characterized as ‘‘ongoing.’’ It is unsurprising that the state has not cited
    to these facts because they are entirely irrelevant in light of undisputed and
    uncontestable evidence that the defendant was fully cooperative from the
    time he was placed in the police cruiser until he was brought into the police
    station and efforts were made to remove his vest. It was on the basis of
    that attenuation evidence that the Appellate Court based its unchallenged
    conclusion that the charges of interference were based on separate, distinct
    acts of alleged interference.
    9
    Although we conclude that a violation of the good cause requirement
    is not sufficient, in and of itself, to mandate reversal of a judgment of
    conviction, we fully expect our trial courts to preclude an amendment in
    the absence of a showing of good cause now that we have stated unequivo-
    cally that to do otherwise would be an abuse of discretion. Indeed, in a
    case like the present one, we would fully expect the trial court not only to
    require such a showing, but also to inquire why the state had failed to make
    its request at the earliest juncture possible. We are particularly troubled by
    the state’s belated request in light of its first amendment to the information
    on the assault charge, its assurances that this amended information reflected
    the proper location for the interference charges, and its silence in the face
    of a request by defense counsel seeking a clarifying instruction to limit the
    jury’s use of evidence regarding the incident in the holding cell in determining
    whether the defendant interfered with the officers.
    10
    Although it appears that almost every jurisdiction imposes by rule or
    statute similar requirements to those in the second and third requirements
    of Practice Book § 36-18, Connecticut appears to be alone in including a
    good cause requirement explicitly in our law.
    11
    These cases do not clearly state which party bears the burden or by
    what standard of proof.
    12
    A few other jurisdictions require reversal on different grounds, namely,
    that such amendments violate certain procedural or jurisdictional prerequi-
    sites. See, e.g., State v. Colwell, 
    124 Idaho 560
    , 566, 
    861 P.2d 1225
    (1993)
    (‘‘any amendment which charges the accused with a crime of greater degree
    or a different nature than that for which the accused was bound over for
    trial by the committing magistrate is barred by the Idaho [c]onstitution’’
    [emphasis omitted]); State v. McKeehan, 
    894 S.W.2d 216
    , 223 (Mo. App.
    1995) (amendment that charges new or different offense violates permissive
    statute and deprives defendant of constitutional and statutory right to prelim-
    inary hearing on new charge). This prohibition on broadening an information
    beyond that which was authorized by the authority prescribed by law is the
    traditional justification for the common-law rule against the amendment of
    an indictment. See Russell v. United States, 
    369 U.S. 749
    , 770, 
    82 S. Ct. 1038
    ,
    
    8 L. Ed. 2d 240
    (1962) (‘‘an indictment may not be amended except by
    resubmission to the grand jury, unless the change is merely a matter of
    form’’); accord Stirone v. United States, 
    361 U.S. 212
    , 215–16, 
    80 S. Ct. 270
    ,
    
    4 L. Ed. 2d 252
    (1960). No issue has been raised in the present case that
    any procedural barrier existed to amending the information other than
    compliance with Practice Book § 36-18.
    13
    The dissent points to the charge of assault at the police station and the
    defendant’s request for an instruction that the jury could not consider his
    conduct at the police station to support the interference charge as evidence
    that the defendant was on notice that the state was advancing the theory
    that the defendant had committed interference at the police station. The
    dissent apparently deems irrelevant the difference between having notice
    of facts to be put in evidence and having notice of the legal significance of
    those facts, as well as how that difference could bear on a defendant’s
    decision whether to testify. Insofar as intent to interfere is an element of
    the charge of assault, the state was required to prove that the defendant
    had such intent when he kicked (assaulted) Smusz. Although the assault
    charge provided notice that conduct preceding the alleged assault could be
    relevant to the defendant’s intent when he purportedly kicked Smusz, it did
    not give the defendant notice that such evidence would be used as a basis
    for independent criminal liability. With respect to the defendant’s requested
    limiting instruction, the dissent ignores the context in which that request
    was made, namely, the defendant’s justifiable reliance on the state’s previous
    two unequivocal affirmations that the information properly limited the inter-
    ference charge to the site of the vehicle stop.
