    STATE OF CONNECTICUT v. TERRELL
    WILLIAMS POND
    (SC 19074)
    Rogers, C. J., and Palmer, Zarella, Eveleigh, McDonald,
    Espinosa and Robinson, Js.
    Argued February 10, 2014—officially released February 10, 2015
    Leonard C. Boyle, deputy chief state’s attorney, with
    whom, on the brief, were Michael Dearington, state’s
    attorney, and John C. Lion, senior assistant state’s
    attorney, for the appellant (state).

    Opinion
    PALMER, J. General Statutes § 53a-48 (a), Connecti-
    cut’s criminal conspiracy statute, provides that ‘‘[a] per-
    son is guilty of conspiracy when, with intent that
    conduct constituting a crime be performed, he agrees
    with one or more persons to engage in or cause the
    performance of such conduct, and any one of them
    commits an overt act in pursuance of such conspiracy.’’1
    The dispositive issue presented by this certified appeal
    is whether, to be convicted of conspiracy, a defendant
    must specifically intend that every element of the
    planned offense be accomplished, even an element that
    itself carries no specific intent requirement. Because
    we are not persuaded that the legislature intended to
    punish offenders for conspiring to commit crimes that
    they never agreed or intended to commit, we conclude
    that § 53a-48 (a) does impose such a requirement.
    The charges in this case arose from an incident in
    which the defendant, Terrell Williams Pond, and his
    friend, Montel Harris, allegedly approached the victim,
    Stanislaw Grzadko, on a public street, and Harris dis-
    played a carbon dioxide (CO2) pistol (air pistol) while
    demanding that Grzadko surrender the contents of his
    pockets. A jury found the defendant not guilty of
    attempt to commit robbery in the second degree but
    found him guilty of conspiracy to commit robbery in
    the second degree in violation of General Statutes (Rev.
    to 2007) § 53a-135 (a) (2)2 and § 53a-48 (a). The trial
    court rendered judgment in accordance with the jury’s
    verdict,3 and the defendant appealed to the Appellate
    Court, claiming, among other things, that the trial court
    improperly had failed to instruct the jury that, to find
    the defendant guilty of the conspiracy charge, it must
    find that he had specifically intended that the planned
    robbery would involve the display or threatened use
    of what Harris represented to be a deadly weapon or
    dangerous instrument.4 The Appellate Court agreed
    with the defendant, reversed the judgment of the trial
    court, and remanded the case for a new trial. State v.
    Pond, 
    138 Conn. App. 228
    , 238–39, 
    50 A.3d 950
     (2012).
    We granted the state’s petition for certification to
    appeal, limited to the following question: ‘‘Did the
    Appellate Court properly determine that in order to
    [establish that] a defendant [is guilty] of conspiracy to
    commit robbery in the second degree in violation of
    . . . §§ 53a-48 (a) and 53a-135 (a) (2), the state must
    prove that the defendant conspirator had the specific
    intent that there would be a display or threat of the use
    of what was represented to be a deadly weapon or
    dangerous instrument, even if that specific intent is not
    required for proof of [that element of] the underlying
    crime of robbery in the second degree?’’ State v. Pond,
    
    307 Conn. 933
    , 
    56 A.3d 714
     (2012).5 We answer the
    certified question in the affirmative and, accordingly,
    affirm the judgment of the Appellate Court.
    The opinion of the Appellate Court, as supplemented
    by the record, sets forth the following facts that the
    jury reasonably could have found. ‘‘On October 27, 2008,
    [Grzadko] . . . ate dinner and then went for his eve-
    ning walk. . . . [W]hile he was walking on the Dixwell
    Avenue sidewalk [in the town of Hamden], he was
    approached from behind by the defendant and . . .
    Harris, both of whom were riding bicycles on the side-
    walk. Harris approached [Grzadko] on his left, the
    defendant approached on his right . . . . Harris asked
    [Grzadko] where he was going and then demanded that
    he stop, repeating the order ‘two [or] three times . . . .’
    When [Grzadko] continued to walk, the defendant
    pushed his bicycle in front of [him], forcing him to stop.
    With [Grzadko] now unable to move forward, Harris
    raised his jacket and lifted the handle of what appeared
    to be a gun, [which] later [was] determined to be [an
    air] pistol, from his waistband, asking [Grzadko], ‘do
    you know what it is?’ When [Grzadko] responded, ‘yes,
    yes, I know,’ and as the defendant continued to block
    [Grzadko] from moving, Harris ordered [Grzadko] to
    remove everything from his pockets. Rather than turn
    his belongings over to the two young men, [Grzadko]
    turned to the side and ran into traffic on Dixwell Avenue
    in order to escape. The defendant and Harris rode off
    on their bicycles. Shortly thereafter, [Grzadko] called
    the Hamden police and reported the incident. Later that
    evening, the Hamden police detained the defendant and
    Harris, and [Grzadko] later identified them as the two
    young men who had accosted him.’’ State v. Pond, supra,
    
    138 Conn. App. 231
    –32.
    The defendant was charged with attempt to commit
    robbery in the second degree and conspiracy to commit
    robbery in the second degree. The case was tried to a
    jury, and the defendant testified in his own defense. In
    addition to denying that he was one of the perpetrators
    of the alleged holdup, the defendant specifically denied
    that he was aware that Harris was carrying an air pistol
    on the evening in question. The only evidence that the
    state proffered with regard to the alleged conspiracy
    was Grzadko’s testimony describing the few minutes
    during which the attempted robbery occurred. Never-
    theless, the jury returned a verdict of guilty on the
    conspiracy count and not guilty on the attempt count.
    The opinion of the Appellate Court sets forth the
    following additional facts concerning the trial court’s
    jury instructions. ‘‘After reading the conspiracy statute
    to the jury, giving general instructions on what was and
    was not required to prove an agreement and instructing
    on the necessity of an overt act, the court stated: ‘The
    third element is that the defendant had the intent to
    commit robbery in the second degree. The intent for
    that crime is that at the time of the agreement he
    intended to commit larceny. The defendant may not
    be found guilty unless the state has proved beyond a
    reasonable doubt that he specifically intended to com-
    mit a larceny when he entered into the agreement. In
    summary, the state must prove beyond a reasonable
    doubt that the defendant had an agreement with one
    or more other persons to commit robbery in the second
    degree, at least one of the coconspirators did an overt
    act in furtherance of the conspiracy, and the defendant
    specifically intended to deprive the owner of his prop-
    erty.’ ’’6 
    Id.,
     237–38.
    On appeal to the Appellate Court, the defendant
    claimed, among other things, that the trial court improp-
    erly had failed to instruct the jury that, to be guilty of
    conspiracy to commit robbery in the second degree
    under §§ 53a-135 (a) (2) and 53a-48 (a), the defendant
    must have specifically intended that his coconspirator
    would display or threaten the use of what the coconspir-
    ator would represent to be a deadly weapon or danger-
    ous instrument.7 Id., 231, 236. In addressing the
    defendant’s claim, the Appellate Court relied on this
    court’s decision in State v. Padua, 
    273 Conn. 138
    , 
    869 A.2d 192
     (2005), for its conclusion that § 53a-48 (a)
    ‘‘requires specific intent to bring about all of the ele-
    ments of the conspired offense, even those that do not
    by themselves carry a specific intent [requirement].’’
    (Emphasis in original.) State v. Pond, supra, 
    138 Conn. App. 234
    . The Appellate Court interpreted Padua to
    mean that, ‘‘in order to prove [that] the defendant [is]
    guilty of conspiracy to commit robbery in the second
    degree in violation of [§§] 53a-135 (a) (2) [and 53a-48
    (a)], the state needed to prove that he and his coconspir-
    ator specifically had an agreement to display a deadly
    weapon or dangerous instrument and that the defendant
    had the specific intent that such a weapon or instrument
    would be displayed.’’ Id. Concluding that the trial court’s
    failure to instruct the jury in accordance with this princi-
    ple as to an essential element of the charged crime was
    not harmless; id., 239; the Appellate Court reversed the
    judgment of the trial court and remanded the case for
    a new trial. Id.
    Judge Borden issued a separate concurrence in which
    he agreed with the Appellate Court majority that that
    court was bound by Padua to conclude that the trial
    court’s instructions to the jury were deficient. Id. (Bor-
    den, J., concurring). Judge Borden also opined, how-
    ever, that imposing a higher mens rea requirement for
    conspiracy than that required to commit the underlying
    or object offense created an unwarranted anomaly in
    the Penal Code, and he therefore invited this court to
    reconsider the interpretation of § 53a-48 (a) that we
    adopted in Padua. See id., 239, 251 (Borden, J., con-
    curring).
    On appeal to this court following our granting of
    certification, the state contends that the language in
    Padua on which both the Appellate Court majority and
    Judge Borden relied was dictum and does not control
    the present case. In the alternative, the state urges us
    to accept Judge Borden’s invitation to reexamine the
    interpretation of § 53a-48 (a) that we adopted in Padua
    and to hold that one need not specifically intend every
    element of robbery in the second degree in order to be
    guilty of conspiracy to commit that offense. For the
    reasons set forth hereinafter, we agree with the Appel-
    late Court that Padua controls the outcome of this case
    and that an essential element of conspiracy to commit
    robbery in the second degree in violation of §§ 53a-135
    (a) (2) and 53a-48 (a) is that the defendant have the
    specific intent, as part of the unlawful agreement, that,
    during the plotted robbery or the immediate flight there-
    from, a coconspirator will display or threaten the use
    of an object that the coconspirator represents to be a
    deadly weapon or dangerous instrument.
    I
    We first consider whether the Appellate Court prop-
    erly concluded that our decision in Padua controls the
    outcome of the present case. We agree that it does.
    In Padua, the defendants were all members of an
    extended family that, for months, had been conducting
    a lucrative drug trafficking operation out of their apart-
    ment in a public housing project; see State v. Padua,
    supra, 
    273 Conn. 143
    –44, 158; an operation that this
    court characterized as ‘‘part of the daily life of the
    household.’’ Id., 158. The defendants were convicted
    of, among other things, conspiracy to sell marijuana
    within 1500 feet of a public housing project. Id., 142.
    At the time, it was settled law that the accused need
    not know that the place of sale is within a protected
    zone to be guilty of the underlying drug crime. See State
    v. Denby, 
    235 Conn. 477
    , 482, 
    668 A.2d 682
     (1995) (state
    need not prove that defendant knew that location of
    narcotics sale was within 1000 feet of school to secure
    conviction under General Statutes [Rev. to 1991] § 21a-
    278a [b]).
    On appeal, the Appellate Court reversed the conspir-
    acy convictions, concluding that the trial court improp-
    erly had instructed the jury that an essential element
    of the charged crime was that the conspiracy must
    have been formed within 1500 feet of a public housing
    project, rather than that the object of the conspiracy
    must have been to sell drugs from such a location. State
    v. Padua, supra, 
    273 Conn. 145
    , 165. On appeal to this
    court, the state conceded that the instruction was incor-
    rect but argued that the impropriety was harmless
    beyond a reasonable doubt because abundant evidence
    in the record, together with the conviction of the defen-
    dants on related drug charges, left no doubt that the
    defendants had in fact knowingly conspired to sell mari-
    juana from their public housing project apartment. 
    Id.,
    165–66. We agreed and reversed the judgment of the
    Appellate Court. Id., 166, 171, 187.
    In construing § 53a-48, we explained that ‘‘[c]onspir-
    acy is a specific intent crime, with the intent divided
    into two elements: [1] the intent to agree or conspire
    and [2] the intent to commit the offense which is the
    object of the conspiracy. . . . Thus, [p]roof of a con-
    spiracy to commit a specific offense requires proof
    that the conspirators intended to bring about the ele-
    ments of the conspired offense. . . . In [Padua], the
    charged object of the conspiracy was to sell marijuana
    within 1500 feet of a public housing project. The essen-
    tial elements of the crime of conspiracy to sell mari-
    juana within 1500 feet of a public housing project are (1)
    intent to agree or conspire, (2) intent to sell marijuana
    within 1500 feet of a public housing project, and (3)
    an overt act committed in pursuance of this conspiracy.
    . . . Thus, it was the state’s burden to establish that
    the defendants conspired or agreed to sell marijuana
    at a specific location within 1500 feet of a public
    housing project . . . .’’ (Citations omitted; emphasis
    added; internal quotation marks omitted.) Id., 167–68.
    In Padua, we repeatedly observed that, to be guilty
    of the charged conspiracy, the defendants must have
    agreed not just to sell marijuana, but to sell it within
    1500 feet of a public housing project, as well. See id.,
    179–80, 182, 183.
    The defendant in the present case, taking the cited
    language at face value, maintains that Padua stands for
    the proposition that, to be guilty of conspiracy, one
    must specifically intend to commit every element of the
    underlying substantive, or object, offense, even when an
    element of that offense itself carries no specific intent
    requirement. The defendant asserts that this interpreta-
    tion of Padua is consistent both with State v. Williams,
    
    182 Conn. 262
    , 266, 
    438 A.2d 80
     (1980), in which we
    held that a jury need not find a defendant guilty of
    the crimes of robbery and conspiracy to commit that
    robbery in the same degree, and with our statement in
    State v. Beccia, 
    199 Conn. 1
    , 
    505 A.2d 683
     (1986), that,
    ‘‘[t]o sustain a conviction for conspiracy to commit a
    particular offense, the [state] must show not only that
    the conspirators intended to agree but also that they
    intended to commit the elements of the offense.’’
    (Emphasis in original; internal quotation marks omit-
    ted.) Id., 4.
    The state reads Padua differently. In Padua, the state
    posits, we merely required that the defendants have
    agreed to sell drugs from a geographic location that
    happened to be situated within 1500 feet of a public
    housing project. To be convicted of conspiracy, the
    defendants did not have to know that the chosen loca-
    tion was close to a public housing project, nor did they
    have to specifically intend to ‘‘violate the protected
    zone . . . .’’ In the present case, by extension, the state
    contends that it was not required to prove that the
    defendant specifically intended or agreed to the ‘‘aggra-
    vating circumstance,’’ namely, that a purported weapon
    would be displayed; rather, the state was required to
    prove only that the defendant agreed to the robbery
    itself.
    The state’s argument relies on the well established,
    if somewhat arcane, distinction between three types
    or categories of essential elements that define each
    criminal offense: conduct, results, and attendant cir-
    cumstances. See, e.g., State v. Beverly, 
    224 Conn. 372
    ,
    378 n.7, 
    618 A.2d 1335
     (1993); P. Robinson & J. Grall,
    ‘‘Element Analysis in Defining Criminal Liability: The
    Model Penal Code and Beyond,’’ 
    35 Stan. L. Rev. 681
    ,
    693 (1983). Under this rubric, conduct elements encom-
    pass all of the various criminal behaviors, such as the
    forming of an agreement to commit a crime or the
    brandishing of a weapon. Results elements, by contrast,
    focus on the outcomes of criminal conduct, such as
    the death of a victim, or the subjecting of a victim to
    substantial risk of bodily injury. With respect to both
    conduct and results elements, attaching a mens rea
    requirement to the criminal element is typically a rela-
    tively straightforward matter.
    Assignment of a mens rea requirement to an attendant
    circumstances element of a criminal offense, by con-
    trast, can be more troublesome. Attendant circum-
    stances encompass elements such as the time or loca-
    tion of a crime, characteristics of the perpetrator or
    victim (e.g., the victim’s age or the perpetrator’s status
    as a convicted felon), or circumstantial features of the
    weapon used (e.g., whether a firearm is registered or
    operational). The problem is that a person may intend
    or agree to commit an offense that satisfies the circum-
    stantial element of a crime without recognizing that it
    does so. For instance, one may agree to commit a bur-
    glary at 7 p.m. on a particular day without knowing
    what time the sun will set that day and, thus, that the
    burglary will take place at night.8 Similarly, one may
    scheme to have sexual relations with a particular
    woman without knowing that she has not yet reached
    the age of consent, or to sell drugs at a particular loca-
    tion without knowing its proximity to the nearest school
    or public housing project. When the legislature assigns
    a mens rea requirement to a circumstantial element of a
    criminal offense, then, there is a potential for ambiguity
    that, for the most part, does not apply to conduct and
    results elements. Specifically, the intent requirement
    may apply merely to the referential aspect of the ele-
    ment (e.g., the intended time, location, or victim of the
    crime), or it also may encompass the descriptive aspect
    of the attendant circumstance (e.g., the fact that the
    intended time, place or victim will, in fact, satisfy the
    circumstantial element of the crime).9
    Returning to the certified question, we note that the
    state reads Padua to mean that, to conspire to commit
    an offense that includes an attendant circumstances
    element, an individual need only have the requisite
    mens rea with respect to the referential aspects of the
    attendant circumstance. In the state’s view, for exam-
    ple, criminal liability for conspiracy would lie in the
    previously described scenarios even if the accused did
    not specifically intend to carry out a night-time bur-
    glary, to seduce a minor, or to sell drugs in a prohib-
    ited location.
    For purposes of this opinion, we assume without
    deciding that our decision in Padua does in fact carve
    out an exception, with respect to the descriptive aspect
    of attendant circumstance offense elements, to the gen-
    eral rule that a defendant may be found guilty of conspir-
    acy under § 53a-48 (a) only when he specifically intends
    that every element of the object crime be committed.10
    We nevertheless conclude that the jury was improperly
    instructed in the present case, because, under the con-
    duct-results-attendant circumstances rubric, the dis-
    play element of § 53a-135 (a) (2) would describe a type
    of criminal conduct rather than an attendant circum-
    stance.
    The display or threatened use of a weapon is quintes-
    sential criminal conduct. See, e.g., People v. Torres, 
    848 P.2d 911
    , 915 (Colo. 1993) (display of weapon deemed
    actus reus of crime of disorderly conduct with deadly
    weapon). Nor is the display or threatened use of a
    weapon subject to the type of reference/description
    ambiguity on which the state’s interpretation of Padua
    hinges. Either a conspirator intends that his associates
    will display a purported weapon during the planned
    robbery, or he does not. There is no middle ground.
    To support its contention that the display of a pur-
    ported weapon represents an attendant circumstance
    rather than a conduct element of the crime of robbery
    in the second degree, the state relies on various deci-
    sions of this court in which we have stated that being
    armed with a deadly weapon is an aggravating circum-
    stance of the crime of robbery. See, e.g., State v. Gonza-
    lez, 
    300 Conn. 490
    , 505, 
    15 A.3d 1049
     (2011). The state’s
    argument is unavailing, however, because it conflates
    two distinct and unrelated meanings of the term ‘‘cir-
    cumstance.’’ In the cases to which the state directs our
    attention, we used the term ‘‘aggravating circumstance’’
    in a general sense to refer to any feature or characteris-
    tic of a crime the presence of which elevates the degree
    of the crime and thus the penalty to which the offender
    is subject. We also have characterized as aggravating
    circumstances many activities and behaviors that
    unequivocally fall under the rubric of conduct and that
    would not qualify as attendant circumstances. See, e.g.,
    State v. Rizzo, 
    303 Conn. 71
    , 152, 
    31 A.3d 1094
     (2011)
    (killing in especially cruel, heinous or depraved man-
    ner), cert. denied,      U.S.     , 
    133 S. Ct. 133
    , 
    184 L. Ed. 2d 64
     (2012); see also Statewide Grievance Com-
    mittee v. Spirer, 
    247 Conn. 762
    , 783 n.14, 
    725 A.2d 948
     (1999) (pattern of misconduct, submission of false
    evidence, and obstruction of disciplinary proceedings).
    More directly on point are our cases construing Gen-
    eral Statutes § 53a-49 (a), which provides in relevant
    part: ‘‘A person is guilty of an attempt to commit a
    crime if, acting with the kind of mental state required
    for commission of the crime, he: (1) Intentionally
    engages in conduct which would constitute the crime
    if attendant circumstances were as he believes them
    to be . . . .’’ (Emphasis added.) In State v. Cox, 
    293 Conn. 234
    , 
    977 A.2d 614
     (2009), we explained that the
    attendant circumstance provision of that statute refers
    to a ‘‘situation [in which] one engages in conduct which
    would constitute the offense if matters were as he per-
    ceived them . . . [but] some mistake in fact prevents
    [the conduct] from being a crime even though the actor
    intends to commit one.’’ 
    Id., 241
    . We provided as exam-
    ples a criminal defendant who seeks to bribe a juror
    but mistakenly approaches a nonjuror; 
    id., 242
    ; or an
    individual who tries to shoot a police officer, unaware
    that his gun is broken. 
    Id., 246
    . By contrast, the conduct
    at issue in the present case—the display of a purported
    weapon—cannot be the subject of that sort of mistake
    and thus would not qualify as an attendant circum-
    stance. See 
    id.
     (concluding that defendant’s display of
    what he later claimed to be BB gun was not attendant
    circumstance for purposes of attempt statute).
    Accordingly, even if we assume without deciding that
    the state is correct that Padua carved out a limited
    exception to the general rule that, to violate § 53a-48
    (a), a coconspirator must intend that every element of
    the object offense be committed, the present case falls
    outside the ambit of that attendant circumstances
    exception. We therefore conclude that the Appellate
    Court properly determined that, under Padua, the trial
    court should have instructed the jury that, to find the
    defendant guilty of conspiracy to commit robbery in
    the second degree in violation of §§ 53a-135 (a) (2) and
    53a-48 (a), it had to find that the defendant specifically
    intended that the robbery would involve the display or
    threatened use of what Harris represented to be a
    deadly weapon or dangerous instrument.
    II
    Although we conclude that the Appellate Court prop-
    erly determined that Padua governs the present case,
    we recognize that, in Padua, we did not explain the
    basis for our conclusion that the legislature, in enacting
    § 53a-48, imposed a specific intent requirement with
    respect to conspiracy that may be stricter than that
    governing the object offense. Accordingly, we accept
    the invitations of the state and Judge Borden in his
    concurrence in the Appellate Court; see State v. Pond,
    supra, 
    138 Conn. App. 239
    , 251 (Borden, J., concurring);
    to revisit the issue, and we take this opportunity to
    explain in greater detail the basis for our conclusion.
    Well settled principles of statutory interpretation gov-
    ern our analysis of § 53a-48. ‘‘Because statutory inter-
    pretation is a question of law, our review is de novo.
    . . . When construing a statute, [o]ur fundamental
    objective is to ascertain and give effect to the apparent
    intent of the legislature. . . . In other words, we seek
    to determine, in a reasoned manner, the meaning of the
    statutory language . . . . In seeking to determine that
    meaning, General Statutes § 1-2z directs us first to con-
    sider the text of the statute itself and its relationship
    to [the broader statutory scheme]. If, after examining
    such text and considering such relationship, the mean-
    ing of such text is plain and unambiguous and does
    not yield absurd or unworkable results, extratextual
    evidence of the meaning of the statute shall not be
    considered. . . . The test to determine ambiguity is
    whether the statute, when read in context, is susceptible
    to more than one reasonable interpretation. . . . When
    a statute is not plain and unambiguous, we also look
    for interpretive guidance to the legislative history and
    circumstances surrounding its enactment, to the legisla-
    tive policy it was designed to implement, and to its
    relationship to existing legislation and common law
    principles governing the same general subject matter
    . . . .’’ (Internal quotation marks omitted.) McCoy v.
    Commissioner of Public Safety, 
    300 Conn. 144
    , 150–51,
    
    12 A.3d 948
     (2011).
    A
    A person is guilty of conspiracy under § 53a-48 (a)
    ‘‘when, with intent that conduct constituting a crime
    be performed, he agrees with one or more persons to
    engage in or cause the performance of such conduct,
    and any one of them commits an overt act in pursuance
    of such conspiracy.’’ To establish a violation of § 53a-
    48 (a), the state must prove that three essential elements
    are satisfied: (1) the accused intended that conduct
    constituting a crime would be performed; (2) the
    accused formed an agreement with one or more persons
    to engage in such conduct; and (3) any one of the cocon-
    spirators performed some overt act in furtherance of
    the conspiracy. E.g., State v. Millan, 
    290 Conn. 816
    , 825,
    
    966 A.2d 699
     (2009). Conspiracy, then, is a ‘‘specific
    intent crime, with the intent divided into two elements:
    [1] the intent to agree or conspire and [2] the intent to
    commit the offense which is the object of the conspir-
    acy.’’ (Internal quotation marks omitted.) State v. Bec-
    cia, supra, 
    199 Conn. 3
    –4. In accordance with General
    Statutes § 53a-51, the penalty for conspiracy is the same
    as the penalty for the object offense, except that con-
    spiracy to commit a class A felony is a class B felony.
    Standing alone, the intent provision of § 53a-48 (a),
    that is, ‘‘with intent that conduct constituting a crime
    be performed,’’ is subject to multiple interpretations.
    As the defendant contends, the statute reasonably can
    be read to require that the accused specifically intend
    that each part of each element of a particular crime,
    the crime that forms the object of the conspiracy, be
    performed. However, the statutory language also could
    simply mean that (1) the accused must enter into the
    conspiracy with a criminal intent, or (2) whatever con-
    duct the accused agrees and intends to perform must,
    in fact, be illegal. In other words, as the state suggests,
    the accused must intend to commit the general class
    or type of crime that constitutes the object of the con-
    spiracy but need not intend to commit conduct consti-
    tuting particular aggravating factors that determine the
    degree of the crime or otherwise impact the sentence
    imposed. Because the statutory language is subject to
    multiple, plausible interpretations, and it does not
    expressly address or resolve the certified question,
    § 53a-48 (a) is facially ambiguous. Cf. L. Alexander &
    K. Kessler, ‘‘Mens Rea and Inchoate Crimes,’’ 
    87 J. Crim. L. & Criminology 1138
    , 1157 (1997) (recognizing ambi-
    guity of similar conspiracy statutes).
    The defendant maintains, however, that any ambigu-
    ity in the intent provision of the conspiracy statute is
    resolved by (1) the agreement provision of that statute,
    and (2) other sections of the Penal Code governing
    inchoate offenses. The defendant first observes that
    § 53a-48 (a) provides that, to conspire to commit a par-
    ticular crime, a person must ‘‘[agree] with one or more
    persons to engage in or cause the performance of . . .
    conduct [constituting the crime] . . . .’’ (Emphasis
    added.) The defendant contends that the italicized lan-
    guage clearly indicates that the intent proscribed by
    the conspiracy statute must be the specific intent to
    commit the precise crime that constitutes the object of
    the conspiracy.
    The state counters that nothing in the express lan-
    guage of § 53a-48 (a) dictates that, if two individuals
    agree and intend to commit conduct constituting simple
    robbery, for example, they may not be subject to a
    heightened penalty if the planned crime ultimately
    involves conduct constituting an aggravating factor
    such as the display of a weapon. Put differently, the
    state’s contention is that the reference in § 53a-48 (a)
    to criminal conduct that constitutes the object of a
    conspiracy is itself subject to multiple interpretations;
    it may be construed broadly, in reference to a type of
    crime, such as robbery, or narrowly, in reference to a
    specific grade or degree of that crime.
    The defendant also argues, however, that any ambigu-
    ities in the text of § 53a-48 (a) may be resolved by
    comparing the statutory language with that of General
    Statutes § 53a-8 (a), which governs accomplice liability,
    and § 53a-49 (a), which governs criminal attempt. The
    defendant contends, and we agree, that, if the legisla-
    ture had intended to impose the same kind of strict
    liability for conspiracy as it did for accomplice liability
    and criminal attempt, it would have used the same statu-
    tory language to characterize the respective mens rea
    requirements. It did not. Compare General Statutes
    § 53a-48 (a) with General Statutes §§ 53a-8 (a) and 53a-
    49 (a).
    The legislature adopted the relevant language of the
    three sections of the Penal Code at the same time, in
    the same public act. See Public Acts 1969, No. 828, §§ 8,
    48 and 50. Section 53a-8 (a) defines the state of mind
    required to be an accessory to a crime as ‘‘the mental
    state required for commission of an offense . . . .’’ Sec-
    tion 53a-49 (a) likewise provides that, to attempt to
    commit a crime, one must act ‘‘with the kind of mental
    state required for commission of the crime . . . .’’ In
    both cases, the legislature expressly provided and
    clearly intended that the mens rea requirement for aid-
    ing in the commission of or attempting to commit a
    crime shall be no different from the mens rea require-
    ment for the commission of a crime by a principal.
    By contrast, § 53a-48 (a) provides that the mens rea
    requirement for conspiracy is the ‘‘intent that conduct
    constituting a crime be performed . . . .’’ It is well
    established that, when construing statutes, we presume
    that the legislature has created a harmonious and con-
    sistent body of law. E.g., Renaissance Management
    Co. v. Connecticut Housing Financial Authority, 
    281 Conn. 227
    , 238, 
    915 A.2d 290
     (2007). Furthermore, when
    ‘‘a statute, with reference to one subject contains a
    given provision, the omission of such provision from
    a similar statute concerning a related subject . . . is
    significant to show that a different intention existed.’’
    (Internal quotation marks omitted.) Hatt v. Burlington
    Coat Factory, 
    263 Conn. 279
    , 310, 
    819 A.2d 260
     (2003). In
    the present case, the legislature, in defining the requisite
    intent for conspiracy in § 53a-48 (a), declined to use
    the language from §§ 53a-8 (a) and 53a-49 (a) providing
    that the intent necessary to violate those statutes is
    identical to the ‘‘mental state required for commission
    of’’ the underlying offense. We presume that this choice
    of statutory language was purposeful and, therefore,
    that the legislature did not intend that the mens rea
    requirement for conspiracy would mirror that of the
    object offense. Accordingly, we agree with the defen-
    dant that the decidedly most reasonable interpretation
    of § 53a-48 (a) is that, to conspire to commit robbery
    in the second degree in violation of §§ 53a-135 (a) (2)
    and 53a-48, a defendant must specifically intend that
    the planned robbery will involve the display or threat-
    ened use of a purported weapon.
    B
    The state nevertheless maintains that, if the legisla-
    ture had intended to require that the state prove a
    greater mens rea for conspiracy to commit robberies
    than for the robberies themselves, it would have done
    so expressly, and that its failure to do so is the clearest
    indication of the intent of § 53a-48 (a). The state also
    contends that construing the statute as we did in Padua
    leads to absurd results. In light of these claims, we look
    to extratextual sources to confirm that our interpreta-
    tion of the statutory language does not depart from
    the intent of the legislature. These sources include the
    legislative policy the statute was designed to imple-
    ment, the legislative history and circumstances sur-
    rounding the enactment of the statute, the relationship
    of the statute to other legislation and common-law prin-
    ciples governing the same general subject matter. E.g.,
    Thomas v. Dept. of Developmental Services, 
    297 Conn. 391
    , 399, 
    999 A.2d 682
     (2010).
    In this case, neither party has brought to our atten-
    tion, and our own review has not identified, anything
    in the legislative history of § 53a-48 (a) that would
    resolve the textual ambiguity or clarify the legislature’s
    intent.11 Rather, the parties have focused their attention
    on two issues: (1) whether the legislature, in enacting
    § 53a-48 (a), could reasonably have intended to impose
    a stricter mens rea requirement for conspiracy than
    that required to commit the crime that constitutes the
    object of that conspiracy; and (2) whether construing
    § 53a-48 (a) in such a manner would be consistent with
    the provisions of the Penal Code governing accessorial
    liability. We answer both questions in the affirmative.
    1
    The state first maintains that the legislature could
    have had no plausible rationale for requiring that a
    person intend that a purported weapon be displayed in
    order to subject him to criminal liability for conspiracy
    to commit robbery in the second degree, when the law
    imposes no such specific intent requirement for the
    robbery itself. Interpreting the statute in such a manner,
    the state contends, would lead to the absurd result of
    requiring that the state prove a more specific mens rea
    to obtain a conviction for conspiracy than that required
    for obtaining a conviction for the commission of the
    plotted offense or serving as an accessory thereto. The
    defendant responds that, because the crime of conspir-
    acy is defined and its punishment is determined with
    respect to the specific object offense at which the illegal
    agreement is directed, it would make no sense to sub-
    ject a person to conviction for conspiring to commit
    crimes that he neither planned nor agreed to commit.
    We agree with the defendant.
    To understand why the intent provision of § 53a-48
    (a) must be interpreted as the defendant contends, it
    is important to recognize the extent to which conspiracy
    differs fundamentally from the substantive crimes that
    may constitute its object. Broadly speaking, the law
    proscribes two stages of the criminal process: (1) the
    actual—or attempted—commission of a crime; and (2)
    prior conduct aimed at planning, preparing for, or solic-
    iting participation in such a crime. There are a number
    of well established differences in how the law treats
    these two stages of the criminal endeavor, reflecting
    the different evils at which the respective prohibitions
    are directed.
    Substantive crimes such as robbery are prohibited,
    first and foremost, because of the direct harms that
    they inflict on the victims, whose rights to be free in
    their persons and property are thereby impaired. For
    example, the commentary to the Penal Code indicates
    that ‘‘[t]he basic rationale [for the criminalization of
    robbery] is protection against the terror of the forcible
    taking.’’ Commission to Revise the Criminal Statutes,
    Penal Code Comments, Conn. Gen. Stat. Ann. § 53a-133
    (West 2012) comment, p. 209. Because of these tangible
    and apparent harms, as well as the ever present risk that
    an attempted or completed crime will lead to further,
    unanticipated injuries to the intended victims, bystand-
    ers, or public safety officers, most substantive crimes
    such as robbery have been recognized in one form or
    another since the earliest days of human civilization.
    See, e.g., Code of Hammurabi § 22 (‘‘[i]f a man has
    committed highway robbery and has been caught, that
    man shall be put to death’’), reprinted in C. Kent, Israel’s
    Laws and Legal Precedents (1907) p. 297.
    Anticipatory crimes such as conspiracy are different.
    As we explained in State v. Johnson, 
    162 Conn. 215
    ,
    
    292 A.2d 903
     (1972), ‘‘[t]he commission of a substantive
    offense and a conspiracy to commit it are separate and
    distinct crimes. . . . [This reflects the fact that] [t]he
    crime of conspiracy . . . has characteristics and ingre-
    dients which separate it from all other crimes.’’ (Cita-
    tions omitted.) Id., 219. Unlike substantive crimes such
    as robbery, for example, conspiracy has no direct vic-
    tims. Rather, ‘‘[t]he gravamen of the crime of conspiracy
    is the unlawful combination . . . . The prohibition of
    conspiracy is directed not at the unlawful object . . .
    but at the process of agreeing to pursue that object.’’
    (Citations omitted; internal quotation marks omitted.)
    State v. Beccia, supra, 
    199 Conn. 3
    . Because conspiracy
    consists primarily of a meeting of minds and a criminal
    intent, ‘‘[i]t is always predominantly mental in composi-
    tion . . . .’’ (Internal quotation marks omitted.) Kru-
    lewitch v. United States,

    , 447–48, 
    69 S. Ct. 716
    , 
    93 L. Ed. 790
     (1949) (Jackson, J., concurring). A
    defendant can be convicted of conspiracy, therefore,
    even if the criminal plot never comes to fruition. See,
    e.g., State v. Flores, 
    301 Conn. 77
    , 96–97, 
    17 A.3d 1025
     (2011).
    Unlike the substantive offenses that constitute its
    objects, the crime of conspiracy itself is of relatively
    modern origins. The notion that one may be punished
    merely for agreeing to engage in criminal conduct was
    unknown to the early common law. 2 W. LaFave, Sub-
    stantive Criminal Law (2d Ed. 2003) § 12.1 (a), p. 254.
    Until the late seventeenth century, the only recognized
    form of criminal conspiracy was an agreement to make
    false accusations or otherwise to misuse the judicial
    process. See id. And it was not until the nineteenth
    century that courts in the United States began to view
    conspiracies as distinct evils. S. Morrison, ‘‘The System
    of Modern Criminal Conspiracy,’’ 
    63 Cath. U. L. Rev. 371
    , 380 (2014). In part, this reflects the law’s traditional
    hesitance to criminalize ideation and communication
    in the absence of actual criminal conduct. See S. Kadish
    et al., Criminal Law and Its Processes: Cases and Materi-
    als (8th Ed. 2007) p. 191.
    That criminal conspiracies ultimately came to be seen
    as crimes in their own right reflects the fact that joint
    criminal plots pose risks to society that, if not unique,
    are undoubtedly greater than those posed by lone-wolf,
    would-be felons. Conspiracies may bolster the resolve
    of their members; they may benefit from the division
    of labor in the execution of criminal schemes; and they
    may lead to the commission of additional crimes beyond
    those initially envisioned. Cf. Krulewitch v. United
    States, 
    supra,
     
    336 U.S. 448
    –49 (Jackson, J., concurring);
    State v. Rodriguez, 
    107 Conn. App. 685
    , 707, 
    946 A.2d 294
    , cert. denied, 
    288 Conn. 904
    , 
    953 A.2d 650
     (2008).
    The predominantly ideational nature of a criminal con-
    spiracy, however, together with the distinct harms that
    the conspiracy laws seek to avert, provides several
    answers to the question why the legislature would have
    imposed a higher mens rea requirement for conspiracies
    than for the underlying substantive offenses.
    First, it stands to reason that the legislature would
    have imposed a higher intent requirement for conspir-
    acy than for some substantive crimes because conspir-
    acy, by its very nature, is ‘‘predominantly mental in
    composition . . . .’’ (Internal quotation marks omit-
    ted.) Krulewitch v. United States, 
    supra,
     
    336 U.S. 447
    –48 (Jackson, J., concurring); see also State v. Johns,
    
    184 Conn. 369
    , 379, 
    439 A.2d 1049
     (1981) (‘‘[t]he essence
    of the conspiracy charge is the illegal agreement’’). In
    contrast to most substantive crimes, which are defined
    principally by their actus rei, or guilty acts, the actual
    conduct required to establish a conspiracy is relatively
    minimal. See, e.g., S. Morrison, supra, 
    63 Cath. U. L. Rev. 408
    . Although it is true that § 53a-48 (a) requires
    that one of the coconspirators have performed an overt
    act in furtherance of the conspiracy, such overt act may
    be de minimus, it may itself be a legal and innocuous
    activity, and it need not be personally performed by
    the accused. See, e.g., State v. Fuller, 
    58 Conn. App. 567
    , 580, 
    754 A.2d 207
    , cert. denied, 
    254 Conn. 918
    , 
    759 A.2d 1026
     (2000); State v. Trumbull, 
    1 Conn. Cir. Ct. 454
    , 467, 
    187 A.2d 445
     (App. Div.), cert. denied, 
    150 Conn. 711
    , 
    204 A.2d 935
     (1962); S. Morrison, supra, 408.
    Moreover, the agreement itself need not be overt or
    formal, and may be established purely by inference. See
    State v. Millan, 
    supra,
     
    290 Conn. 825
    –26. Accordingly,
    just as the legislature has imposed more stringent actus
    reus requirements for substantive offenses that are
    defined principally with respect to their conduct ele-
    ments, so may it reasonably demand a greater showing
    of wrongful intent for an anticipatory, inchoate crime
    such as conspiracy, which predominantly criminalizes
    the wrongful scheme. ‘‘[T]he law makes up, as it were,
    for the deficiency in the actus reus of the crime by
    insisting on a greater degree of mens rea.’’ (Footnote
    omitted.) J. Stannard, ‘‘Making Up for the Missing Ele-
    ment—A Sideways Look at Attempts,’’ 7 Legal Stud.
    194, 194 (1987).
    Second, on the most basic level, it makes sense to
    impose a specific intent requirement for conspiracy to
    commit robbery in the second degree, but not for rob-
    bery in the second degree, because one crime actually
    involves the display or threatened use of a purported
    weapon and the other does not. The substantive crime
    of robbery in the second degree, as defined in § 53a-
    135 (a) (2), requires that, in the course of a robbery or
    immediate flight therefrom, the defendant or another
    perpetrator display or threaten the use of what is repre-
    sented to be a deadly weapon or a dangerous instru-
    ment. An accomplice to an actual or attempted robbery
    may be held criminally liable for his associate’s display
    or threatened use of a purported weapon and thus con-
    victed of the more serious crime of robbery in the sec-
    ond degree, even if he did not intend or even know that
    such a display would occur. See State v. Gonzalez,
    
    supra,
     
    300 Conn. 506
    . In defining the various degrees
    of the crime of robbery, the legislature has made a
    reasonable determination that, if an individual willingly
    participates in a robbery or attempted robbery, during
    which one of the perpetrators actually threatens the use
    of deadly force, that individual should be held criminally
    liable for the increased risk that injury or death will
    result, even if he did not specifically intend for the
    threat to be made.
    It makes little sense, however, to say that, if an indi-
    vidual plans and agrees to participate in a simple,
    unarmed robbery, he then may be held criminally liable
    for planning or agreeing to an armed robbery, or one
    in which a purported weapon is displayed or its use
    threatened, when he had no such intention and agreed
    to no such plan. Such an interpretation of § 53a-48 (a)
    would lead to results that are both absurd and unwel-
    come. For one thing, the state’s interpretation would
    obliterate the distinction between conspiracy to commit
    robbery in the first, second, and third degrees. As we
    previously noted, conspiracy neither requires nor
    entails the commission or attempted commission of the
    object offense. See State v. Flores, 
    supra,
     
    301 Conn. 96
    –97. The crime has only three essential elements: an
    agreement to engage in unlawful conduct, the intent to
    commit a crime, and some minimal overt act evidencing
    that the illicit plan amounts to more than mere phan-
    tasy. See, e.g., State v. Millan, 
    supra,
     
    290 Conn. 825
    .
    All that distinguishes conspiracy to commit robbery in
    the first, second, and third degrees, then, is the object
    offense, that is, whether the conspirators’ intent was
    to commit a crime involving the use of an actual or
    purported weapon. The actual use or display of a
    weapon or purported weapon is not an element of those
    crimes. See State v. Johns, supra, 
    184 Conn. 379
    ; see
    also State v. Beccia, supra, 
    199 Conn. 3
     (‘‘[t]he gravamen
    of the crime of conspiracy is the unlawful combination
    and an act done in pursuance thereof, not the accom-
    plishment of the objective of the conspiracy’’ [internal
    quotation marks omitted]). If, as the state proposes,
    one could be found guilty of conspiracy to commit
    robbery in the second degree merely by virtue of agree-
    ing and planning to commit simple, third degree rob-
    bery, then the elements of those two crimes would
    be identical, and there would be no legal distinction
    between them.
    Pragmatically, the state’s interpretation of § 53a-48
    (a) could lead to unintended and undesirable conse-
    quences. Under the state’s reading of the statute, an
    individual who plans a simple, unarmed robbery never-
    theless can be convicted of the more serious crime of
    conspiracy to commit robbery in the first or second
    degree if weapons are ultimately used without his
    knowledge or consent. In other words, even if, during
    the planning stages of a robbery, the accused vigorously
    and at that time successfully beseeches his coconspira-
    tors not to display or use actual or purported weapons
    during the contemplated crime, he nevertheless may
    be convicted and sentenced just as if he had champi-
    oned their display or use if his coconspirators ultimately
    engaged in such conduct. The reason the law punishes
    conspiracies to commit armed robberies more severely
    is to discourage would-be felons from planning this
    more dangerous class of crime. The state’s proposed
    interpretation of the statute would eliminate any
    such disincentive.
    Third, we presume that the most straightforward
    reading of the statutory language is the correct one and
    that the accused must have specifically intended every
    element of the planned crime, because a contrary inter-
    pretation of § 53a-48 (a) would create the potential for
    abuse. When the state prosecutes a conspiracy, particu-
    larly one that never has ripened into an actual crime,
    it seeks to punish behavior—thought, speech, and col-
    laboration—that would be legal if not for its illicit
    design. It is only the fact that the agreement is directed
    at a criminal object that renders it criminal. Moreover,
    the legislature has determined that conspirators shall
    be subject to punishment only in proportion to the
    seriousness of the offense planned. See General Stat-
    utes § 53a-51 (conspiracy is crime of same grade and
    degree as most serious offense that is object of conspir-
    acy). We see no reason, then, why the state should not
    be made to demonstrate that an individual accused of
    conspiring to commit a class C felony, and facing a
    possible sentence reflective of that more serious crime,
    actually agreed and intended to carry out such a crime.
    To require less would permit the state to prosecute
    a person who conspires with a would-be pickpocket,
    shoplifter or library book bandit for conspiracy to com-
    mit an armed felony without proving that that person
    either intended to or did in fact engage in such a crime.
    Of course, the state is not arguing that an individual
    who has conspired to commit a simple, unarmed rob-
    bery can, on that basis alone, be convicted of robbery
    in the first or second degree. Rather, we understand
    the state’s position to be that, when an individual agrees
    to the commission of a simple robbery, and when the
    coconspirators then follow through and attempt to put
    the conceived plan into effect, that individual becomes
    strictly liable for any unanticipated escalation of the
    robbery, just as he would be criminally liable therefor as
    an accessory or accomplice. There are several problems
    with this reading of the statute.
    One problem is that, as we previously discussed, the
    crime of conspiracy is targeted not at the underlying
    substantive crime but at the illicit agreement itself.
    Before adopting the state’s interpretation of the statute,
    then, we would require a clear indication that the legis-
    lature intended to calibrate the punishment of conspira-
    cies according to the vagaries of the resulting crime, if
    any, rather than according to the scope of the criminal
    agreement itself. The state has made no such showing.
    Another problem is that there simply is no need for
    the state’s proposed rule. The state has § 53a-48 (a)
    at its disposal to prosecute criminal agreements, and
    various substantive criminal statutes are available to
    punish any crimes borne of such agreements. If a con-
    spiracy culminates in an actual robbery, or an attempted
    robbery, each participant in or accessory to that rob-
    bery may be convicted under General Statutes §§ 53a-
    134, 53a-135, or 53a-136, as appropriate, depending on
    the actual criminal conduct involved. Thus, if one partic-
    ipant decides to brandish a gun in what had been
    planned as an unarmed robbery, his accomplices may
    be convicted of robbery in the first degree for their role
    in the crime, regardless of their knowledge or intention
    with regard to the weapon. See State v. Gonzalez, 
    supra,
    300 Conn. 506
    ; see also General Statutes § 53a-8. More-
    over, to the extent that it was reasonably foreseeable
    that a member of the conspiracy might unilaterally
    depart from the plan and use a firearm during the crime,
    every member of the conspiracy—even those who do
    not directly participate in the robbery—could be con-
    victed of the more serious robbery charge, based on a
    Pinkerton12 theory of liability.13 When the object offense
    is actually attempted or committed, then, the state has
    more than adequate remedies at its disposal to hold
    each coconspirator criminally liable in proportion to
    the seriousness of the crime.
    The problem in the present case is that the state
    failed to secure a conviction on the substantive charge.
    The jury unanimously found the defendant not guilty
    of attempt to commit robbery in the second degree.
    There has been no finding, then, that any substantive
    crime ever was attempted or committed. What the state
    seeks is, in essence, a second bite at the apple. It seeks
    to bootstrap a conviction by taking the position that,
    even if the defendant agreed only to commit a third
    degree, unarmed robbery, and even though the jury
    rejected the state’s theory that he attempted to commit
    a robbery involving the display or threatened use of a
    purported weapon, he nonetheless was properly con-
    victed of conspiracy to commit robbery in the second
    degree solely on the basis of those allegations. Imposing
    liability under those circumstances and to that extent
    would turn Pinkerton on its head and dramatically
    expand the already broad reach of conspiracy law. We
    decline to reach such a result, at least in the absence
    of a clear indication of legislative authorization.
    We next address the state’s contention that its inter-
    pretation of § 53a-48 (a) is consonant with the Model
    Penal Code, on which Connecticut’s Penal Code is mod-
    eled; see State v. Courchesne, 
    296 Conn. 622
    , 671–72,
    
    998 A.2d 1
     (2010); and also with the conspiracy law of
    other jurisdictions. We disagree with this contention.
    Considering first the Model Penal Code, the provision
    corresponding to § 53a-48 (a) is Model Penal Code
    § 5.03 (1), which provides in relevant part: ‘‘A person
    is guilty of conspiracy . . . to commit a crime if with
    the purpose of promoting or facilitating its commission
    he: (a) agrees . . . that . . . one or more of [the con-
    spirators] will engage in conduct that constitutes such
    crime . . . .’’ 2 A.L.I., Model Penal Code and Commen-
    taries (1985) § 5.03 (1), pp. 382–83.
    The Model Penal Code’s treatment of the question
    presented in this appeal turns on the distinction we
    previously have discussed between the three types of
    ‘‘elements of an offense,’’ namely conduct, results, and
    attendant circumstances. See 1 id., § 1.13 (9), p. 209.
    The American Law Institute’s explanatory note to § 5.03
    (1) provides that ‘‘[g]uilt as a conspirator is measured
    by the situation as the actor views it; he must have the
    purpose of promoting or facilitating a criminal offense
    . . . . The purpose requirement is meant to extend to
    result and conduct elements of the offense that is the
    object of the conspiracy, but whether or how far it also
    extends to circumstance elements of that offense is
    meant to be left open to interpretation by the courts.’’
    (Emphasis added.) 2 id., § 5.03 (1), explanatory note,
    p. 384. The American Law Institute elaborates in the
    comments to § 5.03: ‘‘It is worth noting, further, that in
    relation to those elements of substantive crimes that
    consist of proscribed conduct or undesirable results of
    conduct, the [Model Penal] Code requires purposeful
    behavior for guilt of conspiracy, regardless of the state
    of mind required by the definition of the substantive
    crime. . . . [T]he actor’s purpose must be to promote
    or facilitate the engaging in of such conduct by himself
    or another.’’ (Emphasis added.) Id., comment 2, p. 407.
    More generally, the drafters of the Model Penal Code
    made clear that one of their primary purposes in framing
    the conspiracy provisions as they did was ‘‘to focus
    inquiry on the culpability of the actor whose liability
    is in issue, rather than on that of the group of which
    he is alleged to be a part.’’ Id., comment 1, p. 393. Thus,
    the Model Penal Code categorically rejects the state’s
    theory that conspiracy carries no greater mens rea
    requirement than that of the object crime. Rather, the
    Model Penal Code requires that the accused have the
    specific purpose—that is, intent—to accomplish each
    conduct and results element of the planned offense.
    The fact that the Model Penal Code takes no position
    with respect to the mens rea requirement governing
    attendant circumstances elements is of little moment,
    because, as we already have explained, the display or
    threatened use of a purported weapon is clearly a con-
    duct element of § 53a-135 (a) (2).
    Nor are we aware of any instance in which a court
    interpreting a conspiracy statute founded on the Model
    Penal Code has applied the rule for which the state
    advocates in the present case. To the contrary, other
    courts repeatedly have held that criminal liability for
    conspiracy lies only when the accused specifically
    intended to commit every element of the plotted
    offense.
    New York law is particularly instructive in this regard.
    See Commission to Revise the Criminal Statutes, supra,
    Conn. Gen. Stat. Ann. § 53a-48a, comment, p. 10 (lan-
    guage of Connecticut conspiracy statute is based on
    revised New York Penal Law); see also State v. Havican,
    
    213 Conn. 593
    , 601, 
    569 A.2d 1089
     (1990) (because draft-
    ers of Connecticut Penal Code ‘‘ ‘relied heavily’ ’’ on
    New York Penal Law, Connecticut courts look to New
    York law for guidance in interpreting ambiguous crimi-
    nal statutes). People v. Joyce, 100 App. Div. 2d 343, 
    474 N.Y.S.2d 337
    , appeal denied, 
    62 N.Y.2d 807
     (1984), a
    decision of the Appellate Division of the New York
    Supreme Court, is squarely on point with respect to the
    present case. In Joyce, the defendant, Robert Patrick
    Joyce, was convicted of conspiracy in the fourth degree,
    in violation of New York Penal Law § 105.10 (McKinney
    Supp. 1979), on the basis of charges that he had con-
    spired to commit burglary in the second degree. Id.,
    344; see id., 346. One element of the latter crime was
    that, during a burglary, the accused or another partici-
    pant display what appears to be a firearm. See 
    N.Y. Penal Law § 140.25
     (1) (d) (McKinney 1981). Under New
    York law, one need not intend or even know that a
    coparticipant in a burglary plans to display a purported
    firearm to be held criminally liable as an accomplice
    in the substantive offense. See People v. Joyce, supra,
    347 n.*. With regard to conspiracy to commit that crime,
    however, the court interpreted ‘‘the plain language’’ of
    
    N.Y. Penal Law § 105.10
     (McKinney Supp. 1979),14 which
    is substantially similar to § 53a-48, to mean that ‘‘the
    [government was required] to prove beyond a reason-
    able doubt that [Joyce] agreed to the display of what
    would appear to be a firearm.’’ Id., 347.15
    Other courts have reached the same conclusion as
    Joyce. See, e.g., People v. Mass, 
    464 Mich. 615
    , 643–44,
    
    628 N.W.2d 540
     (2001); State v. Rodriguez, 
    164 N.H. 800
    , 812, 
    64 A.3d 962
     (2013); State v. Suggs, 
    117 N.C. App. 654
    , 661–62, 
    453 S.E.2d 211
     (1995). English law also
    is relevant to our resolution of the certified question.
    Section 1 (2) of chapter 45 of the Criminal Law Act,
    1977,16 provides: ‘‘Where liability for any offence may
    be incurred without knowledge on the part of the person
    committing it of any particular fact or circumstance
    necessary for the commission of the offence, a person
    shall nevertheless not be guilty of conspiracy to commit
    that offence . . . unless he and at least one other party
    to the agreement intend or know that that fact or cir-
    cumstance shall or will exist at the time when the con-
    duct constituting the offence is to take place.’’ Although
    not controlling, the fact that each of these jurisdictions
    has expressly adopted the principle that, to be crimi-
    nally liable for conspiracy, one must specifically intend
    every element of the object offense seriously under-
    mines the state’s contention that such a rule amounts
    to an ‘‘absurdity . . . .’’
    The state next contends that its interpretation of
    § 53a-48 (a) finds support in federal conspiracy law.
    Specifically, the state argues that United States v. Feola,
    
    420 U.S. 671
    , 
    95 S. Ct. 1255
    , 
    43 L. Ed. 2d 541
     (1975),
    stands for the proposition that federal conspiracy law
    imposes no greater mens rea requirement than that of
    the substantive offense that constitutes the object of
    an alleged conspiracy. Feola, however, is readily distin-
    guishable from the present case. In Feola, the respon-
    dent was convicted of violating the federal conspiracy
    statute, 
    18 U.S.C. § 371
     (1970),17 on the basis of his role
    in a scheme to assault and rob several purported heroin
    buyers who, unbeknownst to him, were undercover
    federal agents. See United States v. Feola, 
    supra, 674
    .
    The offense charged as the object of the conspiracy
    was assault of a federal officer engaged in the perfor-
    mance of his official duties. 
    18 U.S.C. § 111
     (1970); see
    United States v. Feola, 
    supra,
     672–73. On appeal, the
    United States Supreme Court concluded that, to be con-
    victed of the underlying substantive offense, the
    offender need not understand that the victim of his
    assault is a federal officer. United States v. Feola, 
    supra, 676, 684
    . The court reasoned that that element of the
    substantive offense merely serves as the hook needed
    to confer federal jurisdiction and that Congress
    intended that federal officers, who might be engaged
    in locally unpopular law enforcement operations, would
    have the full protection of federal as well as state assault
    laws. See 
    id.,
     683–84. For similar reasons, the court also
    concluded that one may conspire to violate 
    18 U.S.C. § 111
     (1970) without having the specific intent to assault
    a federal agent. See 
    id.,
     695–96.
    We do not read Feola to apply to statutory provisions
    such as the one at issue in the present case. Any compar-
    ison between the federal and Connecticut conspiracy
    statutes is extremely problematic in light of their radi-
    cally different penalty provisions. Under § 53a-51, con-
    spiracy is punishable by a prison term not to exceed
    the maximum term for the object offense, except in the
    case of conspiracy to commit a class A felony. Under
    
    18 U.S.C. § 371
    , by contrast, a conspiracy to commit a
    felony is punishable by a prison term not to exceed five
    years, regardless of the degree or seriousness of that
    felony. See 
    18 U.S.C. § 371
     (1970); see also 
    18 U.S.C. § 371
     (2012) (same). Accordingly, because punishment
    for violation of the federal statute does not depend
    on the degree of the object offense, the United States
    Supreme Court, in construing that statute, simply was
    not confronted with the issue presented by this appeal:
    whether a coconspirator must intend the conduct con-
    stituting the aggravating factors that increase the degree
    of a crime before he may be subjected to increased
    punishment on the basis of the presence of those
    factors.
    We also agree with the defendant that Feola stands
    only for the limited proposition that one need not intend
    an attendant circumstance element of a crime the pri-
    mary purpose of which is to confer federal jurisdiction.
    See United States v. Feola, 
    supra,
     
    420 U.S. 685
    , 687,
    692–94 (distinguishing crime elements based on status
    or identity of intended victim from those relating to
    nature and seriousness of illicit acts or conduct); see
    also id., 696 (‘‘[when] knowledge of the facts giving rise
    to federal jurisdiction is not necessary for conviction of
    a substantive offense embodying a mens rea require-
    ment, such knowledge is equally irrelevant to questions
    of responsibility for conspiracy to commit that offense’’
    [emphasis altered]). Finally, the court in Feola repeat-
    edly emphasized that a criminal agreement is no more
    blameworthy, and the object offense no more danger-
    ous or opprobrious, simply because the participants are
    aware that the offense will violate federal as well as
    state law. See id., 693. The clear implication is that a
    different outcome would be appropriate when, as in the
    present case, the seriousness of the offense is precisely
    what is at issue. Nothing in Feola, then, suggests that
    a person may be held liable for a higher degree of
    conspiracy, and thus exposed to a more severe penalty,
    for having conspired to commit a crime involving con-
    duct constituting an aggravating factor that he neither
    approved of nor intended.
    Accordingly, our review of the statutory text, the
    public policies that animate the law of conspiracy, and
    persuasive authority from other jurisdictions all compel
    the conclusion that, under § 53a-48 (a), the state must
    prove that a person accused of conspiracy to commit
    robbery in the second degree specifically intended that
    every element of that offense be committed.
    2
    We next address the state’s argument that it would
    have been irrational for the legislature to adopt a legisla-
    tive scheme in which offenders face broad vicarious
    liability for their roles in first and second degree robber-
    ies—whether as participants, accessories or, under a
    Pinkerton theory, coconspirators—and yet to stop
    short of extending that same vicarious liability to the
    crime of conspiracy itself under § 53a-48 (a). In this
    opinion, we already have indicated a number of ratio-
    nales for this distinction.
    First, there is a fundamental difference between hold-
    ing a person liable for his role in an actual crime, what-
    ever that role might be, as opposed to punishing him
    solely for agreeing to commit a crime. ‘‘[T]he conspiracy
    doctrine will incriminate persons on the fringe of
    offending who would not be guilty of aiding and abetting
    or of becoming an accessory, for those charges . . .
    lie [only] when an act which is a crime has actually
    been committed.’’ Krulewitch v. United States, supra,
    
    336 U.S. 450
     (Jackson, J., concurring). There are sound
    historical, practical and theoretical reasons for impos-
    ing stricter liability in the latter case than in the former.
    See, e.g., People v. Luciano, New York Supreme Court,
    Docket No. 5715/11 (N.Y. Sup. April 27, 2012) (‘‘It is
    one thing to hold a defendant who intends to commit
    a robbery liable for a limited number of the common
    unintended consequences of that crime. It is another
    to punish a person for entering into an agreement to
    do something he never agreed to do.’’).
    Second, under Pinkerton, coconspirators are already
    held vicariously liable for crimes in which their cocon-
    spirators’ use of weapons or purported weapons is rea-
    sonably foreseeable. The state’s proposed rule would
    represent a substantial expansion of, rather than a mere
    corollary to, that principle. Pinkerton liability is for-
    ward looking, holding conspirators liable as principals
    for crimes that predictably result from an already
    formed and clearly defined conspiracy. The state’s pro-
    posed rule, by contrast, would create a legal anachro-
    nism: it turns back the clock and rewrites the terms of
    the conspirators’ original criminal agreement to reflect
    conduct that coconspirators are alleged to have subse-
    quently performed. Such a rule would substantially ease
    the burden on the state in prosecuting an alleged con-
    spiracy, creating what would, in effect, be a presump-
    tion that conspirators agreed in advance to conduct
    constituting any aggravating factors that are alleged to
    have subsequently transpired. There is no indication
    that the legislature intended to adopt that sort of ‘‘in
    for a penny, in for a pound’’ theory of conspiracy.18
    C
    For all of the foregoing reasons, we conclude that,
    in order to convict a defendant of conspiracy to commit
    robbery in the second degree in violation of §§ 53a-135
    (a) (2) and 53a-48 (a), the state must prove that the
    defendant specifically agreed that there would be the
    display or threatened use of what was represented as
    a deadly weapon or dangerous object during the rob-
    bery or immediate flight therefrom. We therefore agree
    with the Appellate Court that the defendant is entitled
    to a new trial before a properly instructed jury.19
    The judgment of the Appellate Court is affirmed.
    In this opinion ROGERS, C. J., and ZARELLA, EVE-
    LEIGH, McDONALD and ROBINSON, Js., concurred.
    1
    Under General Statutes § 53a-51, the penalty for conspiracy, like the
    penalty for attempt, is the same penalty ‘‘as the most serious offense which
    is . . . an object of the conspiracy, except that . . . conspiracy to commit
    a class A felony is a class B felony.’’
    2
    General Statutes (Rev. to 2007) § 53a-135 (a) provides in relevant part:
    ‘‘A person is guilty of robbery in the second degree when he commits robbery
    . . . and . . . (2) in the course of the commission of the crime or of immedi-
    ate flight therefrom he or another participant in the crime displays or threat-
    ens the use of what he represents by his words or conduct to be a deadly
    weapon or a dangerous instrument.’’
    Hereinafter, all references to § 53a-135 are to the 2007 revision.
    3
    The trial court imposed a sentence of five years imprisonment, execution
    suspended after fifteen months, and three years of probation.
    4
    For the sake of brevity, we sometimes refer to this element of the crime
    of robbery in the second degree as the display of a purported weapon.
    5
    Thereafter, the defendant claimed, as an alternative ground for affirming
    the judgment of the Appellate Court; see Practice Book § 84-11; that there
    is a reasonable probability that certain of the trial court’s jury instructions
    misled the jury. Because we affirm the judgment of the Appellate Court on the
    ground raised in the certified question, we need not address the defendant’s
    alternative ground for affirmance.
    6
    Under Connecticut law, larceny involves the wrongful taking, obtaining,
    or withholding of another person’s property with the intent to deprive that
    other person of that property or to appropriate the same to himself or a
    third person. See General Statutes § 53a-119. Larceny is graded primarily
    on the basis of the value and type of property appropriated. See generally
    General Statutes §§ 53a-119, and 53a-121 through 53a-125b. Robbery entails
    the use or threatened use of force in the course of committing a larceny;
    see General Statutes § 53a-133; and is graded primarily on the basis of the
    type of force or threat applied. See generally General Statutes §§ 53a-134
    through 53a-136a.
    The parties do not dispute that, in order to conspire to commit robbery
    in the second degree in violation of §§ 53a-135 (a) (2) and 53a-48 (a), one
    must specifically intend not only that a larceny occur, but also that force
    be used or threatened with the intent either to overcome resistance or to
    compel delivery of the victim’s property. See General Statutes § 53a-133;
    General Statutes (Rev. to 2007) § 53a-135 (a) (2); cf. State v. Avila, 
    223 Conn. 595
    , 603, 
    613 A.2d 731
     (1992).
    7
    Because the defendant failed to raise this instructional claim at trial, he
    sought to prevail on appeal under State v. Golding, 
    213 Conn. 233

    . He contended that the
    omitted part of the instruction involved an essential element of the charged
    crime and, therefore, that its omission from the court’s instructions to the
    jury represented a constitutional violation.

    Prior to 2008, one element of burglary in the second degree was that
    the crime be committed at night. General Statutes (Rev. to 2007) § 53a-102

    For a discussion of the potential for this sort of ambiguity that character-
    izes so-called ‘‘opaque’’ verbs such as ‘‘intend,’’ see generally J. Anderson,
    ‘‘Misreading Like a Lawyer: Cognitive Bias in Statutory Interpretation,’’

     (2014).

    We note that the state’s interpretation of Padua as carving out an
    exception for attendant circumstances elements hinges on the questionable
    hypothesis that, if we had meant to require that the defendants in that case
    actually intended to sell drugs within 1500 feet of a public housing project,
    we could not have found the instructional error in question to be harmless.
    This is true, the state contends, because there was no evidence in the record
    in Padua that the defendants specifically intended to sell drugs in a protected
    zone. The state, however, overlooks the fact that those defendants apparently
    resided in the public housing project from which they sold drugs over a
    matter of months. See State v. Padua, 
    73 Conn. App. 386
    , 411–12 n.6, 
    808 A.2d 361
     (2002), rev’d, 
    273 Conn. 138
    , 
    869 A.2d 192
     (2005). The state’s theory,
    then, rests on the rather tenuous assumption that the defendants in Padua
    might not have understood that they lived in a public housing project.

    The commentary to the Penal Code does indicate that § 53a-48 differs
    from its predecessor. The commentary provides that the following change
    appeared in § 53a-48: ‘‘the requirement that the defendant must have a
    specific intent to agree in the performance or causation of criminal conduct.
    A general intent to promote or facilitate the criminal object or means is not
    sufficient to establish guilt.’’ Commission to Revise the Criminal Statutes,
    Penal Code Comments, Conn. Gen. Stat. Ann. § 53a-48 (West 2012) comment,
    p. 10. The commentary offers no further guidance, however, as to the scope
    of that specific intent requirement.

    , 43, 45–46, 
    630 A.2d 990
     (1993), we
    recognized the principle of vicarious liability that the United States Supreme
    Court articulated in Pinkerton v. United States, 
    328 U.S. 640
    , 647–48,

     (1946), under which conspirators may be held liable
    for criminal offenses committed by their coconspirators that are (1) within
    the scope of the conspiracy, (2) in furtherance of it, and (3) reasonably
    foreseeable as a necessary or natural consequence of the conspiracy.

    New York Penal Law § 105.10 (McKinney Supp. 1979) provides in rele-
    vant part: ‘‘A person is guilty of conspiracy in the fourth degree when, with
    intent that conduct constituting:
    ‘‘1. a class B or class C felony be performed, he agrees with one or more
    persons to engage in or cause the performance of such conduct . . . .’’

    The state’s efforts to distinguish Joyce are unavailing. The state refers
    to dictum in Joyce indicating that, in the case of a general conspiracy
    statute that does not identify a particular class of object felonies, it ‘‘may
    be appropriate’’ to adopt the rule that ‘‘one who joins a conspiracy after its
    inception, knowing of its central criminal design, may be held accountable
    for the actions and declarations of his coconspirators which occurred before
    his entry into the conspiracy . . . .’’ (Citations omitted; emphasis added.)
    People v. Joyce, supra, 100 App. Div. 2d 347. That possible exception to the
    general rule for which Joyce stands is inapplicable to the present case.

    Title 18 of the 1970 edition of the United States Code, § 371, provides:
    ‘‘If two or more persons conspire either to commit any offense against the
    United States, or to defraud the United States, or any agency thereof in any
    manner or for any purpose, and one or more of such persons do any act
    to effect the object of the conspiracy, each shall be fined not more than
    $10,000 or imprisoned not more than five years, or both.
    ‘‘If, however, the offense, the commission of which is the object of the
    conspiracy, is a misdemeanor only, the punishment for such conspiracy
    shall not exceed the maximum punishment provided for such misdemeanor.’’

    For all of the reasons discussed herein, we are unpersuaded by the
    dissenting opinion. In light of the criticisms leveled by the dissenting justice,
    however, we take this opportunity to underscore that our holding in this case
    does not require that the state prove the existence of a formal conspiracy. Nor
    must the state prove that the defendant knew all of the details of the planned
    crime. There must, however, be at least circumstantial evidence that the
    defendant intended those aspects of the object offense that constitute its
    essential elements and determine the penalty to which an offender is poten-
    tially subject.
    19
    On appeal, the state does not challenge the Appellate Court’s conclusion
    that the trial court’s failure to so instruct the jury constituted harmful error.
