    ROGEAU R. COLLINS v. COMMISSIONER
    OF CORRECTION
    (AC 42785)
    Lavine, Suarez and Devlin, Js.*
    Syllabus
    The petitioner, who had been convicted of felony murder and robbery in
    the first degree, sought a writ of habeas corpus, claiming that his right
    to conflict free counsel was violated and that his trial counsel provided
    ineffective assistance. Specifically, the petitioner claimed that his trial
    counsel had a financial incentive not to retain three expert witnesses
    and that he failed to investigate a potential eyewitness and present her
    testimony. The habeas court rendered judgment denying the habeas
    petition, and the petitioner, on the granting of certification, appealed
    to this court. Held:
    1. The petitioner could not prevail on his claim that the habeas court erred
    in concluding that his trial counsel did not have a conflict of interest:
    a. This court concluded, contrary to the determination of the habeas
    court, that the petitioner’s conflict of interest claim was not procedurally
    defaulted, as it was a type of ineffective assistance of counsel claim
    that typically must be raised by way of habeas corpus, rather than by
    direct appeal, due to the need for a full evidentiary record of the claim;
    neither trial counsel nor the court raised the potential for a conflict of
    interest at trial and, consequently, the record on direct appeal was not
    adequate to review the claim; accordingly, the claim was not subject to
    the procedural default doctrine.
    b. The habeas court properly determined that no actual conflict of
    interest existed because trial counsel did not have an obligation to
    finance the petitioner’s litigation costs or to make his private resources
    available to the petitioner: the fee agreement clearly placed responsibil-
    ity for the payment of experts on the petitioner and his family, and
    counsel’s decision not to advance funds to engage experts after the
    family failed to do so did not violate his duty of loyalty or otherwise
    create a conflict of interest.
    2. The habeas court did not err in determining that the petitioner was not
    denied his constitutional right to the effective assistance of trial counsel,
    reasoning that trial counsel’s failure to investigate the potential eyewit-
    ness did not result in any prejudice to the petitioner’s defense: the
    habeas court’s conclusion that the witness would not have been willing
    to assist the defense at trial, even if she had been contacted by counsel,
    was based on a credibility determination that was not clearly erroneous
    even though the witness stated at the habeas trial that she would have
    testified at the trial if she had been approached by counsel because she
    also testified that she witnessed the shooting, knew that the petitioner
    had been arrested, and yet made no efforts to contact the police; accord-
    ingly, the petitioner did not establish that there was a reasonable proba-
    bility that the trial outcome would have been different if trial counsel
    had investigated the eyewitness.

    Procedural History
    Second amended petition for a writ of habeas corpus,
    brought to the Superior Court in the judicial district
    of Tolland and tried to the court, Kwak, J.; judgment
    denying the petition, from which the petitioner, on the
    granting of certification, appealed to this court.
    Affirmed.
    Jennifer B. Smith, for the appellant (petitioner).
    Timothy F. Costello, senior assistant state’s attorney,
    with whom, on the brief, were Gail P. Hardy, former
    state’s attorney, and Tamara Grosso, assistant state’s
    attorney, for the appellee (respondent).
    Opinion
    DEVLIN, J. The petitioner, Rogeau R. Collins, appeals
    from the judgment of the habeas court, Kwak, J., deny-
    ing his petition for a writ of habeas corpus. On appeal,
    the petitioner claims that the court improperly (1) deter-
    mined that his conflict of interest claim was procedur-
    ally defaulted and that, in any event, his trial counsel
    did not have a conflict of interest and (2) denied his
    ineffective assistance of counsel claim. We affirm the
    judgment of the habeas court.
    The following recitation of facts was set forth by this
    court in the petitioner’s direct appeal from his convic-
    tion. ‘‘In March, 2009, Robert Dixon, the victim, resided
    in Hartford with his girlfriend. Dixon always carried
    two cell phones. He used one cell phone to sell drugs
    and the other for personal matters. In addition, he
    always wore an expensive pair of Cartier glasses. He
    did not store the drugs he sold at his home, but kept
    them at a remote location secured in a safe. The key
    to the safe was on the same key ring as Dixon’s car keys.
    ‘‘On March 9, 2009, Dixon exchanged several phone
    calls with an individual named Adrian Dean, a friend
    of the [petitioner]. At approximately 9:25 p.m. that night,
    Dixon left his residence in his vehicle carrying both of
    his cell phones and wearing his Cartier glasses. Some-
    time thereafter, Dean joined Dixon in the vehicle. Dean
    then contacted the [petitioner], who was driving around
    the Hartford area in his girlfriend’s vehicle. Dean
    arranged to meet the [petitioner] at a location in Bloom-
    field and gave the [petitioner] directions to that loca-
    tion. The [petitioner] followed Dean’s directions and
    arrived at the location at approximately the same time
    as Dean and Dixon. Dixon and the [petitioner] then
    drove their vehicles toward a cul-de-sac at the end of
    the road. Dixon turned his vehicle in the cul-de-sac and
    came to a stop. The [petitioner] pulled up and stopped
    his vehicle to the left of Dixon’s vehicle. The [petitioner]
    then exited his vehicle. Both the [petitioner] and Dean,
    who had exited Dixon’s vehicle, approached the driver’s
    side door of Dixon’s vehicle. Dixon was still sitting in
    the driver’s seat of his vehicle. Dean, with a firearm in
    one of his hands, opened the driver’s side door of Dix-
    on’s vehicle and shot Dixon in the head. Dean then
    asked the [petitioner] to search Dixon’s pockets. The
    [petitioner] began patting Dixon’s pockets when Dixon
    flinched and attempted to escape the vehicle through
    the passenger side door. Dixon was shot seven times
    as he attempted to escape and died as a result of the
    multiple gunshot wounds. The [petitioner] and Dean
    then left the scene in the [petitioner’s] vehicle. The
    following morning, on March 10, 2009, Dixon was found
    dead by two fishermen. Dixon’s two cell phones, Cartier
    glasses, and keys were not found at the scene. The
    [petitioner] was arrested on March 24, 2009.
    ‘‘The state, in a long form information filed on January
    11, 2011, charged the [petitioner] with murder in viola-
    tion of General Statutes § 53a-54a (a), felony murder
    in violation of [General Statutes] § 53a-54c, conspiracy
    to commit murder in violation of General Statutes
    §§ 53a-48 (a) and 53a-54a (a), robbery in the first degree
    in violation of [General Statutes] § 53a-134 (a) (2), and
    conspiracy to commit robbery in the first degree in
    violation of §§ 53a-48 (a) and 53a-134 (a) (2). The jury
    found the [petitioner] guilty of felony murder and rob-
    bery in the first degree, but not guilty [of] each of the
    remaining charges. The court sentenced the [petitioner]
    to a total effective term of forty-five years of imprison-
    ment.’’ State v. Collins,

    (2014). This court affirmed the trial court’s judgment
    on appeal. 
    Id., 598
    .
    On March 23, 2015, the self-represented petitioner
    filed a petition for a writ of habeas corpus. The peti-
    tioner filed an amended petition with the assistance of
    counsel on February 14, 2018, which was again
    amended on April 10, 2018. The second amended peti-
    tion contained four counts, only two of which are rele-
    vant to this appeal.1 In the first count, the petitioner
    alleged that his trial counsel, Aaron Romano, had a
    conflict of interest and, thus, rendered ineffective assis-
    tance. In the second count, the petitioner alleged that
    Romano was ineffective for failing to investigate and
    present a potentially exculpatory witness to the rob-
    bery, Teara Rosario, and that such failure materially
    prejudiced the petitioner’s case.2
    A trial on the habeas petition was held on June 8 and
    12, 2018. On December 28, 2018, the habeas court issued
    a memorandum of decision in which it denied each of
    the petitioner’s claims. Specifically, as to the first count,
    the court concluded that the petitioner’s conflict of
    interest claim was procedurally defaulted and that, even
    if it were not, the petitioner had failed to demonstrate
    that Romano had a conflict of interest. As to the second
    count, the court agreed with the petitioner that Romano
    was ineffective in not investigating the potentially
    exculpatory witness but also found that ‘‘it would be
    too speculative to assess whether the absence of [the
    witness’] testimony at the criminal trial inured to the
    petitioner’s prejudice.’’ Thereafter, the petitioner filed
    a petition for certification to appeal from the judgment
    denying his petition for a writ of habeas corpus. The
    habeas court granted the petition for certification to
    appeal. Additional facts will be set forth as necessary.
    Before we turn to the petitioner’s claims, we briefly
    set forth our standard of review for habeas corpus
    appeals. ‘‘The habeas court is afforded broad discretion
    in making its factual findings, and those findings will
    not be disturbed unless they are clearly erroneous. . . .
    Historical facts constitute a recital of external events
    and the credibility of their narrators. . . . Accordingly,
    [t]he habeas judge, as the trier of facts, is the sole arbiter
    of the credibility of witnesses and the weight to be
    given to their testimony. . . . The application of the
    habeas court’s factual findings to the pertinent legal
    standard, however, presents a mixed question of law
    and fact, which is subject to plenary review.’’ (Citations
    omitted; internal quotation marks omitted.) Gaines v.
    Commissioner of Correction,

    , 677, 
    51 A.3d 948
     (2012).
    I
    The petitioner first claims that the habeas court erred
    in concluding that his conflict of interest claim was
    procedurally defaulted and that, even if it were not,
    Romano did not have an actual conflict of interest that
    rendered his representation ineffective. Although we
    agree that the petitioner’s claim was not procedurally
    defaulted, we also agree with the habeas court’s conclu-
    sion that Romano did not have a conflict of interest.
    The following additional facts are relevant to our
    resolution of this claim. After he was arrested, the peti-
    tioner was found to be indigent and initially a special
    public defender was appointed for him. The petitioner’s
    family retained Romano on February 27, 2010, to repre-
    sent the petitioner in lieu of a special public defender.
    The petitioner’s father signed a representation agree-
    ment, agreeing to pay Romano a retainer of $25,000,
    which included the trial fee, should the case proceed
    to trial. The father also agreed that, ‘‘[i]f in the opinion
    of [counsel], the services of experts or private investiga-
    tors or the acquisition of medical, police, or other inves-
    tigatory reports are necessary in defending [the peti-
    tioner] in the abovementioned matter, I agree to pay
    the additional costs and fees that may arise as a result
    of securing these services.’’
    On March 10, 2010, Romano filed a motion for
    expenses pursuant to Ake v. Oklahoma, 
    470 U.S. 68
    , 87,
    
    105 S. Ct. 1087
    , 
    84 L. Ed. 2d 53
     (1985),3 arguing that the
    petitioner was indigent and that state funding of expert
    witnesses was necessary in order to provide effective
    assistance of counsel. Specifically, Romano claimed
    that he needed a ballistics expert to challenge the state’s
    firearms expert, a cell phone expert to challenge the
    state’s cell phone expert, a psychologist or psychiatrist
    to opine on the voluntariness of the petitioner’s state-
    ments, and an independent medical examiner to deter-
    mine the trajectory of the bullets. The court, Mullarkey,
    J., conducted an evidentiary hearing over the course
    of three days. Ultimately, the court denied the request
    for expenses, concluding that Romano had failed to
    make a sufficiently particularized showing of need for
    the experts and that the petitioner’s indigency was vol-
    untary.4 The court explained that, because the petition-
    er’s family had decided to retain and pay Romano, the
    petitioner was voluntarily indigent. The court recom-
    mended that Romano pay for experts to review the case
    using funds he already had received and consult with
    the state’s experts, such as the state medical examiner,
    before deciding if independent experts were necessary.
    Additionally, before adjourning, the court specifically
    instructed the petitioner that ‘‘the state will pay for all
    experts that the Chief Public Defender’s office deter-
    mines are necessary if you’re represented by the pub-
    lic defender.’’
    Prior to trial, on January 19, 2011, Romano filed an
    amended motion for expenses, arguing again that the
    petitioner was indigent and that experts were absolutely
    necessary to his defense. After a hearing on the motion
    held on February 8, 2011, the court, Espinosa, J., denied
    the motion, finding that ‘‘[t]he [petitioner] had access
    to a special public defender, with all of the advantages
    and resources that the Office of the Public Defender
    could provide. The [petitioner] knowingly and wilfully
    rejected those services by having a private counsel file
    an appearance in this case.’’ The court also recom-
    mended that Romano consider spending a portion of
    the fee that he received on experts and then subse-
    quently seek reimbursement from the petitioner’s fam-
    ily, pursuant to the provision in the retainer agreement.
    On February 8, 2011, the petitioner moved to suppress
    his statements made to the police, arguing that the
    statements were tainted, as they were obtained as the
    result of an arrest made without probable cause, and
    were involuntary. Romano presented no expert testi-
    mony to support the argument, nor did he argue specifi-
    cally that the petitioner’s cognitive deficiencies affected
    the voluntariness of the statements. The court denied
    the motion, finding that the statements were made
    knowingly and voluntarily. The introduction of evi-
    dence at trial began on March 15, 2011. Romano did
    not present any expert witnesses at trial.
    A
    The petitioner argues that the habeas court’s determi-
    nation that his conflict of interest claim was procedur-
    ally defaulted because he did not raise the claim at
    trial or on direct appeal was improper. We agree with
    the petitioner.
    A habeas court’s conclusion that a petitioner’s claim
    was in procedural default involves a question of law,
    over which our review is plenary. Johnson v. Commis-
    sioner of Correction, 
    285 Conn. 556
    , 566, 
    941 A.2d 248
     (2008).
    We begin with a review of the procedural default
    rule. ‘‘Under the procedural default doctrine, a [peti-
    tioner] may not raise, in a collateral proceeding, claims
    that he could have made at trial or on direct appeal in
    the original proceeding, unless he can prove that his
    default by failure to do so should be excused.’’ (Internal
    quotation marks omitted.) Cator v. Commissioner of
    Correction, 
    181 Conn. App. 167
    , 199, 
    185 A.3d 601
    , cert.
    denied, 
    329 Conn. 902
    , 
    184 A.3d 1214
     (2018). Ordinarily,
    if the state ‘‘alleges that a [petitioner] should be proce-
    durally defaulted from now making the claim, the [peti-
    tioner] bears the burden of demonstrating good cause
    for having failed to raise the claim directly, and he must
    show that he suffered actual prejudice as a result of
    this excusable failure.’’ Hinds v. Commissioner of Cor-
    rection, 
    151 Conn. App. 837
    , 852, 
    97 A.3d 986
     (2014),
    aff’d, 
    321 Conn. 56
    , 
    136 A.3d 596
     (2016). This cause and
    prejudice test derives from Wainwright v. Sykes, 
    433 U.S. 72
    , 
    97 S. Ct. 2497
    , 
    53 L. Ed. 2d 594
     (1977), and
    was held by our Supreme Court to be ‘‘the appropriate
    standard for reviewability in a habeas corpus proceed-
    ing of constitutional claims not adequately preserved
    at trial because of a procedural default . . . .’’ Johnson
    v. Commissioner of Correction, 
    218 Conn. 403
    , 409, 
    589 A.2d 1214
     (1991); see also Jackson v. Commissioner
    of Correction, 
    227 Conn. 124
    , 132, 
    629 A.2d 413
     (1993)
    (holding that ‘‘the Wainwright cause and prejudice
    standard should be employed to determine the review-
    ability of habeas claims that were not properly pursued
    on direct appeal’’). The procedural default doctrine,
    however, is limited to claims that could have been raised
    at the trial level. See Hinds v. Commissioner of Correc-
    tion, 
    supra, 853
    .
    Conflict of interest claims are a species of ineffective
    assistance of counsel claims. See Santiago v. Commis-
    sioner of Correction, 
    87 Conn. App. 568
    , 582, 
    867 A.2d 70
    , cert. denied, 
    273 Conn. 930
    , 
    873 A.2d 997
     (2005)
    (‘‘[w]here a constitutional right to counsel exists, our
    [s]ixth [a]mendment cases hold that there is a correla-
    tive right to representation that is free from conflicts
    of interest’’). Our Supreme Court has explained that
    ineffective assistance of counsel claims are generally
    more appropriately resolved on collateral review:
    ‘‘Almost without exception, we have required that a
    claim of ineffective assistance of counsel must be raised
    by way of habeas corpus, rather than by direct appeal,
    because of the need for a full evidentiary record for
    such [a] claim. . . . Moreover, we have stated as our
    preference that all of the claims of ineffective assis-
    tance, those arguably supported by the record as well
    as others requiring an evidentiary hearing, be evaluated
    by the same trier in the same proceeding. . . . On the
    rare occasions that we have addressed an ineffective
    assistance of counsel claim on direct appeal, we have
    limited our review to allegations that the defendant’s
    sixth amendment rights had been jeopardized by the
    actions of the trial court,5 rather than by those of his
    counsel. . . . We have addressed such claims, more-
    over, only where the record of the trial court’s allegedly
    improper action was adequate for review or the issue
    presented was a question of law, not one of fact requir-
    ing further evidentiary development.’’ (Citations omit-
    ted; emphasis in original; footnote added; internal quo-
    tation marks omitted.) State v. Crespo,

    ,

    of interest claim on direct appeal), cert. denied,

    , 
    119 S. Ct. 911
    , 
    142 L. Ed. 2d 909
     (1999).
    In State v. Navarro, 
    172 Conn. App. 472
    , 474, 
    160 A.3d 1116
    , cert. denied, 
    326 Conn. 910
    , 
    164 A.3d 681
    (2017), this court examined a conflict of interest claim
    predicated on dual representation. In declining to
    review the claim on direct appeal, this court stated that
    the defendant’s ‘‘ineffective assistance [claim] should
    be resolved . . . after an evidentiary hearing in the trial
    court where the attorney whose conduct is in question
    may have an opportunity to testify.’’ (Internal quotation
    marks omitted.) Id., 491. The same need for testimony
    applies to the present case. Romano never raised the
    potential for a conflict of interest with the court, nor
    did the court raise the issue on its own. As such, it was
    not until the habeas trial itself that Romano explained
    on the record specifically why he declined to pay for
    experts using the retainer. Thus, we see no reason to
    depart from our Supreme Court’s guidance that ineffec-
    tive assistance of counsel claims are more appropriately
    resolved on collateral review. We conclude that the
    petitioner’s conflict of interest claim is not subject to
    the procedural default doctrine and decline to apply
    the Wainwright cause and prejudice test, as the record
    on direct appeal was not adequate to review the claim.6
    B
    Having concluded that the petitioner’s claim is not
    subject to procedural default, we proceed to consider
    the merits of his conflict of interest claim. The petitioner
    argues that Romano had an actual conflict of interest
    ‘‘because he had a personal financial incentive to not
    retain and present the testimony of three experts once
    the trial court denied his motion for state funding for
    the cost of those experts.’’7 We are not persuaded.
    We begin by setting forth the general legal principles
    concerning conflicts of interest in the representation
    of criminal defendants. ‘‘It is well established that the
    sixth amendment to the United States constitution guar-
    antees the right to effective assistance of counsel. . . .
    Where a constitutional right to counsel exists, our
    [s]ixth [a]mendment cases hold that there is a correla-
    tive right to representation that is free from conflicts of
    interest.’’ (Citations omitted; internal quotation marks
    omitted.) State v. Vega, 
    259 Conn. 374
    , 386, 
    788 A.2d 1221
    , cert. denied, 
    537 U.S. 836
    , 
    123 S. Ct. 152
    , 
    154 L. Ed. 2d 56
     (2002).8
    ‘‘In a case of a claimed conflict of interest . . . in
    order to establish a violation of the sixth amendment the
    defendant has a two-pronged task. He must establish
    (1) that counsel actively represented conflicting inter-
    ests and (2) that an actual conflict of interest adversely
    affected his lawyer’s performance. . . . Where there is
    an actual conflict of interest, prejudice is presumed
    because counsel [has] breach[ed] the duty of loyalty,
    perhaps the most basic of counsel’s duties. Moreover,
    it is difficult to measure the precise effect on the defense
    of representation corrupted by conflicting interests.
    . . . Accordingly, an ineffectiveness claim predicated
    on an actual conflict of interest is unlike other ineffec-
    tiveness claims in that the petitioner need not establish
    actual prejudice.’’ (Emphasis in original; internal quota-
    tion marks omitted.) Grover v. Commissioner of Cor-
    rection, 
    183 Conn. App. 804
    , 813,

    denied, 
    330 Conn. 933
    , 
    194 A.3d 1196
     (2018).
    ‘‘An actual conflict of interest is more than a theoret-
    ical conflict. The United States Supreme Court has cau-
    tioned that the possibility of conflict is insufficient to
    impugn a criminal conviction. . . . A conflict is merely
    a potential conflict of interest if the interests of the
    defendant may place the attorney under inconsistent
    duties at some time in the future. . . . To demonstrate
    an actual conflict of interest, the petitioner must be

    The petitioner claims that Romano breached his duty
    of loyalty to him when Romano declined to use his
    retainer to pay expert witness fees. Specifically, in his
    brief, the petitioner states: ‘‘Here, counsel’s representa-
    tion of the petitioner was materially limited because he
    had a financial interest in not presenting the testimony
    of these experts because he would have had to use his
    retainer fee to pay for them. His financial interests were
    inconsistent with the petitioner’s interests, who had an
    interest in challenging the state’s evidence and mount-
    ing a defense to these serious charges by way of presen-
    tation of expert testimony on three important issues.’’
    We can identify no Connecticut or federal authority
    holding that counsel’s failure to apply funds from a
    retainer agreement to the hiring of expert witnesses
    creates a conflict of interest. This court previously has
    found no conflict of interest where a fee agreement
    provided for a fixed fee of $7500 for all work leading
    up to trial and payment of $250 an hour with a $5000
    retainer once the case was placed on the trial list. See
    Grover v. Commissioner of Correction, supra, 
    183 Conn. App. 808
    , 814. The petitioner in Grover was
    unable to pay the full trial retainer and, subsequently,
    accepted a plea agreement. Id., 809. In his habeas peti-
    tion the petitioner claimed ‘‘that [counsel] had a finan-
    cial incentive to convince the petitioner to accept a
    plea rather than proceed to trial due to the fact that the
    petitioner was unable to pay [counsel’s] trial retainer
    in full.’’ Id. This court declined to find a conflict of
    interest, explaining that ‘‘[w]e do not agree that the
    petitioner’s inability to pay the outstanding balance of
    the trial retainer created such a conflict. According
    to the testimony of [counsel], which the habeas court
    credited in its entirety, although he was disappointed
    that the trial retainer had not been paid in full, [counsel]
    valued his professional reputation above any single fee.
    He testified that his advice throughout the pendency
    of the criminal case was based on his overall assessment
    of the facts and not the financial situation of the peti-
    tioner.’’ Id., 814–15. Moreover, this court has also con-
    cluded that a $300,000 retainer for the entire representa-
    tion, without regard to whether the case was resolved
    by plea agreement or trial, does not represent an actual
    conflict of interest. See Shefelbine v. Commissioner of
    Correction, supra, 
    150 Conn. App. 193
    .
    Federal courts have rejected conflict of interest
    claims arising from fee agreements similar to the one
    in the present case. In Williams v. Vasquez, 
    817 F. Supp. 1443
    , 1472 (E.D. Cal. 1993), aff’d sub nom. Williams v.
    Calderon, 
    52 F.3d 1465
     (9th Cir. 1995), cert. denied,

    , 
    116 S. Ct. 1588
    , 
    134 L. Ed. 2d 686
     (1996), the
    petitioner claimed that his trial counsel had a conflict
    of interest because ‘‘he was placed in the position
    whereby he had to personally pay for ancillary defense
    services, or [forgo] the use of such services.’’ (Internal
    quotation marks omitted.) 
    Id.
     In rejecting this claim,
    the District Court for the Eastern District of California
    stated: ‘‘Although the [s]ixth [a]mendment guarantee of
    effective assistance of counsel includes the collateral
    right to counsel’s undivided loyalty . . . counsel’s duty
    of loyalty does not impose an ancillary obligation to
    personally finance his client’s defense investigation
    and/or expert costs. In other words, no conflict of inter-
    est existed. Counsel’s failure to financially support [the]
    [p]etitioner’s defense does not constitute a violation
    of his duty of loyalty or of [the] [p]etitioner’s [s]ixth
    [a]mendment right to effective assistance of counsel.’’
    (Citations omitted.) Id., 1473. In affirming the judgment
    of the District Court, the Court of Appeals for the Ninth
    Circuit observed: ‘‘The quality of such representation
    might well improve if counsel were to volunteer to
    place her private financial resources at [the] defendant’s
    disposal. As the [D]istrict [C]ourt correctly noted, coun-
    sel is under no obligation to do so.’’ Williams v. Calde-
    ron, 
    52 F.3d 1465
    , 1473 (9th Cir. 1995), cert. denied,

    In Bonin v. Calderon, 
    59 F.3d 815
    , 827 (9th Cir. 1995),
    the United States Court of Appeals for the Ninth Circuit
    again considered a habeas petitioner’s claim that his
    trial counsel had a conflict of interest because trial
    counsel’s substitution as retained counsel deprived the
    defendant of state funded investigators and expert wit-
    nesses, thereby requiring counsel to pay for any investi-
    gators or experts out of his own pocket. In rejecting
    this claim, the court noted that ‘‘[t]his allegation of
    conflict is . . . inadequate under Cuyler [v. Sullivan,
    
    supra,
     
    446 U.S. 335
    ]. . . . [A]n assertion of conflict
    based on the fact that payment for any investigation or
    psychiatric services could have come from counsel’s
    pocket [forcing] counsel to choose between [the cli-
    ent’s] interests and his own . . . is the same theoretical
    conflict that exists . . . in any pro bono or
    underfunded appointment case. . . . While such
    arrangements create a theoretical conflict of interest,
    they do not typically create actual conflicts under
    Cuyler.’’ (Citations omitted; internal quotation marks
    omitted.) 
    Id.
    In United States v. Stitt, 
    552 F.3d 345
    , 350 (4th Cir.
    2008), cert. denied, 
    558 U.S. 831
    , 
    130 S. Ct. 65
    , 
    175 L. Ed. 2d 48
     (2009), the petitioner argued that ‘‘under the
    financial agreement between him and [counsel], [coun-
    sel] was required to pay for all case-related expenses
    out of his own pocket and that [counsel], not wishing
    to incur the costs of an out-of-state investigator, thus
    declined to pursue any investigation [out of state].’’
    However, the United States Court of Appeals for the
    Fourth Circuit noted that the District Court had made
    the express factual finding, to the contrary, that counsel
    ‘‘were paid flat fees for their services, with costs and
    expenses to be paid as they arose . . . . Petitioner’s
    family agreed to raise the money for any additional costs
    and expenses.’’ (Internal quotation marks omitted.) Id.,
    351. After determining that this finding was not clearly
    erroneous, the court concluded that a fee agreement
    where counsel is paid a flat fee and must seek additional
    costs and expenses from the petitioner’s family did not
    represent an actual conflict. Id.
    The petitioner in the present case asserts that Wil-
    liams, Bonin, and Stitt are distinguishable because the
    written fee agreement in the present case allowed
    Romano to advance the funds for experts and then
    pursue legal action against the petitioner’s family for
    reimbursement. The petitioner’s effort to distinguish
    Williams, Bonin, and Stitt on the ground that Romano
    could bring an action for reimbursement is unpersua-
    sive. The fact that there might be a theoretical path to
    reimbursement does not create a conflict of interest
    where otherwise one does not exist. Those cases stand
    for the proposition that trial counsel has no obligation
    to finance a defendant’s litigation costs and, further, is
    under no obligation to put counsel’s private resources
    at the defendant’s disposal. Advancing funds for experts
    amounts to exactly that.
    The petitioner relies heavily on State v. Cheatham,
    
    296 Kan. 417
    , 
    292 P.3d 318
     (2013), for the proposition
    that ‘‘[a] fee agreement creates a conflict of interest
    between a client and his attorney where the fee agree-
    ment pits the attorney’s interest in getting paid against
    those of the client.’’ In Cheatham, the Kansas Supreme
    Court addressed the propriety of a flat fee arrangement
    in a death penalty case and concluded that the agree-
    ment in that case did constitute a conflict of interest.
    Id., 453. However, the court stressed several key facts
    that differentiate Cheatham from the present case.
    First, counsel in Cheatham was not paid any fees before
    the trial and thus operated under the presumption that
    there was ‘‘little likelihood of any payment because [the
    defendant] was indigent, which [counsel] knew.’’ Id.
    Indeed, by the time of collateral proceedings, counsel
    testified that he still was owed the $50,000 retainer. Id.,
    451. Second, ‘‘[counsel], a solo practitioner with a ‘high
    volume’ law practice requiring near daily court appear-
    ances, [had] little financial incentive to invest the signifi-
    cant time commitment a capital case requires.’’ Id., 453–
    54. Additionally, we note that when counsel in
    Cheatham took the case he was aware that the defen-
    dant would not be able to pay for expenses or expert
    witnesses. Id., 422. Ultimately, the court in Cheatham
    characterized the representation as ‘‘[bearing] a greater
    resemblance to a personal hobby engaged in for diver-
    sion rather than an occupation that carried with it a
    responsibility for zealous advocacy.’’ Id., 454. An unpaid
    flat fee agreement in a death penalty case that incentiv-
    izes an attorney to do no more than the minimum neces-
    sary to secure a fee rather than seek acquittal is far
    from the situation in the present case, in which a written
    fee agreement placed the responsibility to pay for
    experts and investigators squarely on the petitioner’s
    family. We find Cheatham inapposite to the claimed
    conflict of interest in the present case.
    Given that this court has declined to find a conflict
    of interest between a defendant and counsel in flat
    fee cases, consistent with our holdings in Grover and
    Shefelbine and the holdings in the federal case law cited
    herein, we conclude that Romano did not have an actual
    conflict of interest. The fee structure in the present case
    is essentially the same fee structure that was present
    in Stitt, for which the Court of Appeals for the Fourth
    Circuit concluded there was no actual conflict of inter-
    est. See United States v. Stitt, 
    supra,
     
    552 F.3d 351
    .
    Further, an actual conflict of interest is more than a
    theoretical conflict. The United States Supreme Court
    has cautioned that ‘‘the possibility of conflict is insuffi-
    cient to impugn a criminal conviction.’’ Cuyler v. Sulli-
    van, 
    supra,
     
    446 U.S. 350
    . A conflict is merely ‘‘a potential
    conflict of interest if the interests of the defendant may
    place the attorney under inconsistent duties at some
    time in the future.’’ (Emphasis in original; internal quo-
    tation marks omitted.) Santiago v. Commissioner of
    Correction, supra, 
    87 Conn. App. 589
    . In the present
    case, there was a written fee agreement that clearly
    delineated the financial arrangement involved in
    Romano’s representation of the petitioner. The respon-
    sibility to pay for experts and investigators was placed
    squarely on the petitioner and his family. When they
    defaulted on this obligation, counsel’s decision not to
    advance funds for experts did not violate his duty of
    loyalty or otherwise create a conflict of interest.9 We
    therefore cannot conclude that Romano had an actual
    conflict of interest.
    Because we conclude that there was no actual con-
    flict of interest between the petitioner and Romano, we
    do not reach the second prong of the conflict of interest
    analysis concerning whether the conflict of interest
    adversely affected counsel’s performance.
    II
    The petitioner next claims that the habeas court
    improperly concluded that he received effective assis-
    tance of counsel. Specifically, the petitioner claims that
    the habeas court correctly concluded that Romano’s
    performance was deficient for failing to investigate a
    potential witness, but that the court erred in concluding
    that Romano’s failure to investigate the witness and to
    present her testimony did not prejudice the petitioner’s
    case. We do not agree.
    The following additional facts are relevant to our
    resolution of this claim. The petitioner testified at the
    habeas trial that he did not have a gun with him on the
    night of the shooting and that Dean ordered him at
    gunpoint to participate in the robbery. He claimed that
    he was ordered to pat down the victim, but that he did
    not fire any shots. This testimony was contradicted by
    the ballistics evidence presented at the criminal trial,
    which suggested that there were bullets fired from two
    different guns based on distinctive ballistic markings.
    The petitioner contends that trial testimony from the
    potential witness could have corroborated his version
    of the events, namely, that he was acting under duress
    when he participated in the robbery.
    The petitioner testified at the habeas trial that there
    was a woman, Rosario, in his car with him on the night
    of the murder who witnessed the shooting. At the time,
    he only knew the woman as ‘‘T.’’ He explained that he
    saw the woman on the street that night and that,
    because he had not seen her in four years, she got into
    his car and joined him as they drove around Hartford.
    After his arrest, the petitioner explained to the police
    that he had picked up the woman earlier that night. He
    told the police that she rode in the backseat of the car
    to the location of the murder and was dropped off
    afterward on Mather Street in Hartford. He described
    the witness to the police as ‘‘half black and half Spanish
    with a funny nose and a big forehead’’ with ‘‘shoulder
    length’’ hair and mentioned that she hangs out at a
    smoke shop on Mather Street, but he was not able to
    provide her name. It was not until the petitioner was
    incarcerated that he learned from another inmate that
    the witness’ name is Teara Rosario.
    The petitioner also testified at the habeas trial that
    he had told Romano to find ‘‘T’’ and that she lived on
    Marvin Street. Romano testified that he was aware of
    the description of the woman in the police report and
    that he and the petitioner had discussed the potential
    witness. He considered the woman to be a potential
    witness, but, due to the petitioner’s vague description
    of her and lack of a name, he thought that it was doubtful
    that an investigator would be able to locate the woman.
    Romano testified at the habeas trial that he believed
    that hiring a private investigator to find Rosario was
    necessary and that he requested expenses to do so.
    After his motion for expenses was denied, Romano
    made no effort to locate the woman either personally
    or through a private investigator. After learning of the
    witness’ name while he was incarcerated, the petitioner
    was able to hire a private investigator to locate Rosario
    for the habeas trial. Rosario testified at the habeas trial
    that she ran into the petitioner in Hartford on the eve-
    ning of the shooting and got into his car. While she was
    driving around with the petitioner, he received a ‘‘chirp’’
    from Dean on his push-to-talk mobile phone. Rosario
    heard Dean ask the petitioner to pick him up and give
    him a ride. Rosario testified that there was no mention
    of a robbery or plans to confront Dixon on this call.
    The petitioner first drove to a house where Dean had
    indicated that he was located. Upon determining that
    Dean was not there, they drove for approximately ten
    minutes and parked near a hotel, where Rosario saw
    Dean standing near another car in which Dixon, the
    victim, was seated in the driver’s seat. Dean started
    walking toward the petitioner’s vehicle. Rosario testi-
    fied that Dean had a gun but that the petitioner did not.
    Dean opened the petitioner’s car door and ordered him
    out of the car. Rosario then saw Dean and the petitioner
    approach Dixon’s car, where Dean pointed his gun at
    Dixon and said something to the petitioner. The peti-
    tioner leaned into the car to pat down Dixon, then
    stepped away from the car, at which point Dean started
    shooting at Dixon. Although Rosario testified that only
    Dean had a gun, at one point she also stated ‘‘[a]nd
    then they just start shooting.’’10 Rosario stayed in the
    petitioner’s car during the confrontation and could not
    hear what was said between the three men. After the
    petitioner and Dean ran back to the petitioner’s car,
    Rosario asked to be dropped off.
    Rosario was asked at the habeas trial ‘‘had the
    defense attorney come and found you, would you have
    testified at [the petitioner’s] trial and told this story?’’
    She responded that she would have done so. However,
    she also testified that she was aware that a crime had
    been committed and had made no efforts to speak to
    the police even after hearing that the petitioner had
    been arrested, despite characterizing their relationship
    as that of ‘‘good friends.’’ She then explained on redirect
    that she did not go to the police because she did not
    want to be involved, as she was afraid that she would
    end up in jail or that the victim’s family or Dean’s family
    could hurt her or her family.
    The habeas court agreed that the petitioner provided
    Romano with ‘‘very little useful information’’ that could
    be used to locate the woman but ultimately ruled that
    counsel’s representation was deficient because counsel
    took no steps to locate her: ‘‘Hiring one or more . . .
    expert witnesses can readily be distinguished from uti-
    lizing an investigator to find and interview a potential
    fact or eyewitness who is identified in the police report.
    The police report placed an unknown woman (i.e., ‘T’)
    inside the vehicle during the robbery and shooting. Rea-
    sonably competent defense counsel would hire and uti-
    lize an investigator to conduct an investigation that is
    limited in scope: finding ‘T’ and discerning if she had
    information that would assist the defense. The court
    finds that . . . Romano was deficient for not utilizing
    an investigator to locate . . . Rosario.’’
    However, the court concluded that Romano’s failure
    to investigate Rosario did not result in prejudice to the
    petitioner. The court found that ‘‘she was not willing
    to come forward and assist the defense at the time of
    the trial for fear of the codefendant, Dean. Efforts by
    counsel to locate . . . Rosario would not, therefore,
    have likely resulted in her cooperating with the investi-
    gation in a manner that assisted the defense.’’ Ulti-
    mately, the habeas court determined that, ‘‘[a]lthough
    this court has concluded that . . . Romano was defi-
    cient for not utilizing an investigator to locate . . .
    Rosario, it would be too speculative to assess whether
    the absence of her testimony at the criminal trial inured
    to the petitioner’s prejudice.’’
    As a preliminary matter, we set forth the general
    principles surrounding ineffective assistance of counsel
    claims and our standard of review. ‘‘In Strickland v.
    Washington, [
    466 U.S. 668
    , 
    104 S. Ct. 2052
    , 
    80 L. Ed. 2d 674
     (1984)], the United States Supreme Court estab-
    lished that for a petitioner to prevail on a claim of
    ineffective assistance of counsel, he must show that
    counsel’s assistance was so defective as to require
    reversal of [the] conviction . . . . That requires the
    petitioner to show (1) that counsel’s performance was
    deficient and (2) that the deficient performance preju-
    diced the defense. . . . Unless a [petitioner] makes
    both showings, it cannot be said that the conviction
    . . . resulted from a breakdown in the adversary pro-
    cess that renders the result unreliable. . . . Because
    both prongs . . . must be established for a habeas peti-
    tioner to prevail, a court may dismiss a petitioner’s
    claim if he fails to meet either prong.’’ (Internal quota-
    tion marks omitted.) Vazquez v. Commissioner of Cor-
    rection,

    , 
    22 A.3d 1277
     (2011).
    As to the first prong, the habeas court found that
    Romano’s representation was deficient because
    Romano did not hire an investigator to locate and to
    interview Rosario. The respondent, the Commissioner
    of Correction, has not challenged this finding on appeal.
    ‘‘To satisfy the second prong of Strickland, that his
    counsel’s deficient performance prejudiced his defense,
    the petitioner must establish that, as a result of his
    trial counsel’s deficient performance, there remains a
    probability sufficient to undermine confidence in the
    verdict that resulted in his appeal. . . . The second
    prong is thus satisfied if the petitioner can demonstrate
    that there is a reasonable probability that, but for that
    ineffectiveness, the outcome would have been differ-
    ent.’’ (Internal quotation marks omitted.) Horn v. Com-
    missioner of Correction,

    , 776,

    ‘‘In a habeas appeal, although this court cannot dis-
    turb the underlying facts found by the habeas court
    unless they are clearly erroneous, our review of whether
    the facts as found by the habeas court constituted a
    violation of the petitioner’s constitutional right to effec-
    tive assistance of counsel is plenary.’’ (Internal quota-

     (2010). With the
    foregoing principles in mind, we now address the merits
    of the petitioner’s claim.
    The petitioner claims that the court erred in conclud-
    ing that Romano’s failure to investigate Rosario and to
    present her testimony did not prejudice the petitioner’s
    case. We are not persuaded. Because the court’s conclu-
    sion was premised on a factual finding, we first apply
    the clearly erroneous standard of review to that find-
    ing.11 ‘‘The habeas court is afforded broad discretion in
    making its factual findings, and those findings will not
    be disturbed [on appeal] unless they are clearly errone-
    ous. . . . Thus, [t]his court does not retry the case or
    evaluate the credibility of the witnesses. . . . Rather,
    we must defer to the [trier of fact’s] assessment of
    the credibility of the witnesses based on its firsthand
    observation of their conduct, demeanor and attitude.
    . . . The habeas judge, as the trier of facts, is the sole
    arbiter of the credibility of witnesses and the weight
    to be given to their testimony. . . . Thus, the court’s
    factual findings are entitled to great weight. . . . Fur-
    thermore, [a] finding of fact is clearly erroneous when
    there is no evidence in the record to support it . . .
    or when although there is evidence to support it, the
    reviewing court on the entire evidence is left with the
    definite and firm conviction that a mistake has been
    committed.’’ (Citations omitted; internal quotation

    284 Conn. 724
    , 741–42,

     (2007).
    The habeas court’s conclusion of no prejudice was
    predicated on its finding that Rosario would not have
    been willing to assist the defense at the time of the
    trial. Although the petitioner stresses that Rosario
    responded in the affirmative when asked if she would
    have testified if approached by defense counsel, there
    is sufficient support in the record to discredit her state-
    ment. Even after characterizing her relationship with
    the petitioner as that of ‘‘good friends’’ and unequivo-
    cally stating that she witnessed Dean shoot the victim
    and that she knew the petitioner had been arrested,
    Rosario testified that she made no efforts to contact
    the police to tell them what she had witnessed. The
    following colloquy occurred on redirect examination
    of Rosario:
    ‘‘Q. Miss Rosario, why didn’t you go to the police?
    ‘‘A. Because I didn’t want to be involved.
    ‘‘Q. Why not?
    ‘‘A. I have a life and children and I was pregnant. And
    I didn’t know what possibly—what could happen. . . .
    ‘‘Q. Did you believe that someone could hurt you or
    your family if you came forward in this case?
    ‘‘A. Yes. . . .
    ‘‘Q. Who were you afraid might hurt you or your
    family?
    ‘‘A. The victim’s family or [Dean’s] family.’’
    In arguing that the court’s factual finding is clearly
    erroneous, the petitioner contends that ‘‘[t]he habeas
    court ignored the distinction between Rosario not com-
    ing forward independently, and Rosario coming for-
    ward if she was approached by trial counsel and asked
    to testify.’’ However, we agree with the respondent that
    ‘‘[t]he habeas court’s conclusion that the petitioner
    failed to establish that Rosario would have presented
    helpful testimony amounted to a discrediting of her
    testimony that, if she had been located and called to
    testify at the criminal trial, she would have testified in
    the same manner as she testified at the habeas trial.’’
    The habeas court’s finding that Rosario was not willing
    to assist the defense at the time of the trial is an implicit
    credibility finding. The habeas court was free to reject
    her testimony that she would have testified at the peti-
    tioner’s criminal trial as she did at the habeas trial. We
    must assume that the habeas court carefully weighed
    Rosario’s testimony that she would have cooperated if
    approached by counsel against her testimony that she
    was afraid to be involved, and found the former to be
    not credible. ‘‘[A] pure credibility determination . . .
    is unassailable.’’ Breton v. Commissioner of Correction,
    
    325 Conn. 640
    , 694, 
    159 A.3d 1112
     (2017); see also San-
    chez v. Commissioner of Correction, 
    314 Conn. 585
    ,
    604, 
    103 A.3d 954
     (2014) (‘‘[W]e must defer to the [trier
    of fact’s] assessment of the credibility of the witnesses
    based on its firsthand observation of their conduct,
    demeanor and attitude. . . . The habeas judge, as the
    trier of facts, is the sole arbiter of the credibility of
    witnesses and the weight to be given to their testimony.’’
    (Internal quotation marks omitted.)). Accordingly, we
    cannot conclude that the habeas court’s factual finding
    is clearly erroneous.
    Having accepted the habeas court’s finding that Rosa-
    rio would not have assisted the defense at the time of
    trial, we agree with the habeas court’s ultimate conclu-
    sion that Romano’s failure to investigate the potential
    witness resulted in no prejudice to the petitioner’s
    defense. We agree with the habeas court’s conclusion
    that ‘‘it would be too speculative to assess whether the
    absence of her testimony at the criminal trial inured to
    the petitioner’s prejudice.’’ The petitioner cannot estab-
    lish that there is a reasonable probability that the out-
    come of his trial would have been different even if
    Romano had investigated Rosario.12
    Because we have concluded that the habeas court’s
    ruling was proper pursuant to its credibility determina-
    tion of Rosario, we decline to address the petitioner’s
    claim that the habeas court erroneously found that
    Rosario did not substantially corroborate the petition-
    er’s version of events.
    The judgment is affirmed.
    In this opinion the other judges concurred.

    The second amended habeas petition included claims of conflict of inter-
    est, ineffective assistance of trial counsel, a violation of due process, and
    actual innocence. The habeas court denied all four counts. On appeal, the
    petitioner challenges only the counts pertaining to conflict of interest and
    ineffective assistance of counsel.
    2
    The petitioner alleged seventeen potential failures of trial counsel in the
    second amended petition, but he advances only the failure to investigate
    Rosario on appeal. The habeas court denied all seventeen allegations of
    ineffective assistance.
    3
    In Ake v. Oklahoma, 
    supra,
     
    470 U.S. 86
    –87, the United States Supreme
    Court held that, when an indigent defendant’s mental state at the time of
    the offense is likely to be a significant factor at trial, due process requires
    that a state provide access to a psychiatric expert to assist in preparing
    a defense.
    4
    The petitioner has not challenged the indigency finding or the denial of
    the motion for expenses.
    5
    Because the petitioner argues on appeal that the conflict of interest
    arises from the conduct of Romano in not paying for experts himself, rather
    than from the trial court’s findings of indigency and denial of the various
    motions for funding for expert witnesses, we conclude that this exception
    does not apply to the petitioner’s appeal.
    6
    In support of its assertion that the petitioner’s conflict of interest claim
    is procedurally defaulted, the respondent, the Commissioner of Correction,
    has also framed this claim as a failure to appeal from the denial of the
    motions for ancillary expenses and the findings of indigency. Specifically,
    the respondent argues that ‘‘[b]ecause the petitioner has presented no evi-
    dence and argument to explain why he did not previously challenge the
    trial court’s ruling on Romano’s request for ancillary funds, and has only
    argued why he did not claim a conflict of interest at trial and on direct
    appeal, he necessarily has failed to establish the requisite cause and prejudice
    to excuse his procedural default.’’ The petitioner’s claim, however, is directed
    not at the denial of the motions for ancillary expenses but rather at Romano’s
    conduct in the aftermath of such denials. We conclude that the petitioner’s
    failure to raise the trial courts’ indigency findings and denial of payment
    for ancillary expenses in his direct appeal does not preclude the petitioner
    from making a conflict of interest claim in a habeas corpus proceeding.
    7
    We note that the petitioner does not argue on appeal that his counsel’s
    failure to call the experts constituted ineffective assistance.
    8
    The petitioner’s statement of issues and introductory portion of his
    conflict of interest argument also aver that his rights under article first, §§ 8
    and 9, of the constitution of Connecticut were violated. However, beyond
    these cursory mentions, the petitioner’s brief does not contain any substan-
    tive analysis of potential Connecticut constitutional violations. Accordingly,
    we decline to review these claims. See State v. Buhl, 
    321 Conn. 688
    , 724,
    
    138 A.3d 868
     (2016) (‘‘We repeatedly have stated that [w]e are not required
    to review issues that have been improperly presented to this court through
    an inadequate brief. . . . Analysis, rather than mere abstract assertion, is
    required in order to avoid abandoning an issue by failure to brief the issue
    properly.’’ (Internal quotation marks omitted.)).
    9
    As the respondent, the Commissioner of Correction, correctly points
    out, if Romano unreasonably failed to investigate the petitioner’s case or
    to present any expert witness at trial, the petitioner’s recourse would be to
    claim, under Strickland v. Washington, 
    466 U.S. 668
    , 
    104 S. Ct. 2052
    , 
    80 L. Ed. 2d 674
     (1984), that Romano rendered ineffective assistance of counsel.
    In the present case, the petitioner made that claim only with respect to
    Romano’s failure to locate and to call Rosario, the potential eyewitness.
    10
    Insofar as this statement suggests that there were two shooters, we
    note that the petitioner describes this statement as a mistake, which is
    amply supported by evidence in the record, as Rosario repeatedly testified
    that Dean was the only person with a gun.
    11
    The petitioner, citing State v. Clark, 
    297 Conn. 1
    , 
    997 A.2d 461
     (2010),
    claims that ‘‘when a constitutional issue turns upon a factual finding, a
    reviewing court must conduct a scrupulous examination of the record to
    determine whether a lower court’s finding is supported by substantial evi-
    dence.’’ Although Clark includes language supporting that statement, Clark
    and the line of cases cited therein make it clear that the substantial evidence
    standard applies to ‘‘review of a trial court’s findings and conclusions in
    connection with a motion to suppress.’’ 
    Id., 7
    ; see State v. DeMarco, 
    311 Conn. 510
    , 519, 
    88 A.3d 491
     (2014); State v. Burroughs, 
    288 Conn. 836
    , 843,
    
    955 A.2d 43
     (2008). Accordingly, we apply the well established definition
    of clearly erroneous when evaluating the court’s factual findings.
    12
    We note that the petitioner claims that ‘‘the habeas court failed to
    state and apply the correct prejudice standard—the ‘reasonable probability’
    standard. . . . Nowhere in the habeas court’s decision . . . does it state
    or apply the ‘reasonable probability’ standard.’’ We agree with the respondent
    that the habeas court expressly stated that it was applying the prejudice
    test from Strickland, which is the reasonable probability standard. The
    habeas court appropriately and extensively discussed the relevant principles
    from Strickland, as well as our Supreme Court’s ineffective assistance of
    counsel jurisprudence as set forth in Gaines v. Commissioner of Correction,
    supra, 
    306 Conn. 664
    . The mere fact that the habeas court did not use the
    precise phrase ‘‘reasonable probability’’ in its conclusion regarding Rosario’s
    testimony is insufficient to give us the impression that the court failed to
    apply the appropriate standard, particularly where we have agreed with the
    habeas court’s prejudice determination.
