    COMMONWEALTH   vs.   JOSEPH COUSIN.
    Suffolk.        September 5, 2017. - January 11, 2018.

    Indictments found and returned in the Superior Court
    Department on September 4, 2002.
    The cases were tried before Nancy Holtz, J., and a motion
    for a new trial, filed on March 1, 2013, was heard by Janet L.
    Sanders, J.
    The Supreme Judicial Court granted an application for
    direct appellate review.

    Assistant District Attorney, also present) for the Commonwealth.
    Robert F. Shaw, Jr., for the defendant.
    LOWY, J.     Following a jury trial in the Superior Court, the
    defendant, Joseph Cousin (Cousin), was convicted of murder in
    the second degree.    Cousin filed a motion for a new trial,
    2
    claiming that his trial counsel was ineffective because he was
    burdened by an actual conflict of interest.     A Superior Court
    judge granted Cousin's motion for a new trial.    The Commonwealth
    appealed, and we allowed its application for direct appellate
    review.1   The issue before this court is whether Cousin presented
    sufficient evidence to establish that his trial counsel was
    burdened by an actual conflict of interest.     Although Cousin has
    set forth the basis for what may well constitute a potential
    conflict of interest, we conclude that he failed to meet his
    burden of demonstrating that his trial counsel was operating
    under an actual conflict of interest.    Therefore, we vacate the
    allowance of Cousin's motion for a new trial and remand the case
    to the Superior Court for further proceedings to determine
    whether there was a potential conflict causing prejudice that
    would warrant a new trial.
    1.    Prior proceedings and background.   We briefly indicate
    the nature of Cousin's criminal case, followed by a summary of
    the facts pertinent to Cousin's conflict claim, as they were
    found by the judge.    We also reserve certain facts for later
    discussion.
    Following an investigation by the Boston police department
    1
    The Commonwealth also moved for reconsideration of the
    motion judge's decision and to reopen the evidence. Following a
    hearing on that motion, the judge issued an amended memorandum
    but otherwise declined to reopen the evidence or reconsider her
    decision.

    (BPD) homicide division, Cousin and another man were charged
    with murder for the shooting death of a young girl.   In 2004,
    Cousin and his codefendant were tried jointly for the murder,
    and the jury acquitted the codefendant.   The jury were
    deadlocked concerning Cousin, and eventually a mistrial was
    declared.   In Commonwealth v. Cousin, 
    449 Mass. 809
    , 815-816,
    823 (2007), cert. denied, 
    553 U.S. 1007
    (2008), we determined
    that double jeopardy did not bar Cousin's retrial because the
    prosecutor's inquiry into the jurors' criminal records during
    deliberation was not government misconduct intended to goad the
    defendant into moving for a mistrial.
    Cousin was retried for the murder in 2009, and was
    represented by Attorney William White (White).   Cousin was
    convicted of murder in the second degree, and he was later
    sentenced to life in prison.   His direct appeal from his
    conviction to the Appeals Court has been stayed pending the
    outcome of this case.
    In the meantime, Cousin, represented by new counsel, moved
    for a new trial, arguing that White was burdened by an actual
    conflict of interest.   The primary grounds for the alleged
    actual conflict were the involvement of White and his former law
    firm in two Federal civil rights lawsuits.   Specifically, White
    and his former law partners defended members of the BPD who were
    accused of misconduct in the course of other, unrelated criminal
    4
    investigations.
    The judge, who was not the trial judge, held three days of
    evidentiary hearings before granting Cousin's motion.       We
    present the pertinent facts she found in her written memorandum
    of decision and order.
    a.     White and the Federal civil rights cases.   White joined
    the law firm of Davis, Robinson & White (DRW) as a partner in
    the early 1990s.    DRW was comprised of three partners:     White,
    Willie Davis, and Frances Robinson.    White concentrated
    primarily on criminal defense, and he and Robinson
    intermittently represented police officers in disciplinary and
    administrative hearings.    An attorney for the Boston police
    patrolmen's union occasionally referred police discipline cases
    to Robinson; however, there was no indication that Robinson or
    DRW had a formal contractual relationship with the patrolmen's
    union, the BPD, or the city of Boston (city).
    DRW was organized as a limited liability partnership.        The
    partners did not share profits or fees, and each partner earned
    only the money he or she generated.    The partners generally
    worked independently on cases, particularly their criminal
    matters.    The partners did, however, share common overhead
    expenses and office resources.    Occasionally, the DRW partners
    would meet to discuss their cases.    However, there is no
    indication that these informal discussions involved the
    5
    disclosure of confidential client information.
    White left DRW in early 2007 and formed his own law firm,
    William White & Associates (White & Associates).     Several years
    thereafter, White operated White & Associates in office space he
    rented in the same building as DRW; however, his firm was
    neither connected to, nor was his practice affiliated with, DRW.
    At the hearing on Cousin's motion, White testified that after he
    left DRW, his former partners only referred him a limited number
    of civil litigation matters.     In January, 2009, the same year as
    Cousin's second trial, White relocated his firm to a different
    office building in Boston.
    Cousin's claim that White was burdened by an actual
    conflict of interest focused primarily on the involvement of
    White and Robinson in two Federal civil rights cases, Drumgold
    vs. Callahan, U.S. Dist. Ct., No. 04-11193-NG (D. Mass. 2004)
    (Drumgold), and Cowans vs. Boston, U.S. Dist. Ct. No. 05-11574-
    GGS (D. Mass. 2005) (Cowans). The plaintiffs in the Drumgold and
    Cowans cases alleged that BPD homicide investigators had
    committed acts of police misconduct that led to their erroneous
    convictions, which were later overturned.     Cousin's motion
    relies heavily on the purported similarities between the police
    investigations underlying the Drumgold and Cowans cases and his
    own.
    i.   Robinson's involvement in the Cowans case.   The judge
    6
    found that Robinson represented Rosemary McLaughlin, a member of
    BPD's latent fingerprint unit, who was a named defendant in the
    Cowans civil rights lawsuit.
    Stephen Cowans was convicted of a shooting, in part based
    on fingerprints that were recovered from the crime scene and
    that McLaughlin, and another member of BPD's latent fingerprint
    unit whose work McLaughlin verified, matched to him.2    Several
    years later, items from the crime scene underwent
    deoxyribonucleic acid (DNA) testing.   The testing revealed that
    Cowans's DNA was not present on any of the items.     A further
    internal investigation also revealed that a latent fingerprint
    recovered from the crime scene had been erroneously
    individualized to Cowans.   Based on this investigation, in 2004,
    the Commonwealth joined in Cowan's motion for a new trial and
    the conviction was vacated.
    Following his exoneration, Cowans filed the Federal civil
    rights lawsuit seeking damages against the BPD and certain
    officers involved in the investigation, including McLaughlin.
    Robinson filed her notice of appearance on behalf of McLaughlin
    on April 5, 2006.3   Cowans's complaint alleged that McLaughlin
    had discovered but concealed the fact that his fingerprints had
    2
    The full factual background of that case is set forth in
    Commonwealth v. Cowans, 
    52 Mass. App. Ct. 811
    , 812-813 (2001).

    The record is unclear concerning how Robinson came to
    represent McLaughlin.
    7
    been erroneously matched to the those recovered at the crime
    scene.     The claims against McLaughlin focused exclusively on her
    involvement in Cowans's investigation and did not implicate her
    conduct in other investigations.     Robinson represented
    McLaughlin until the Cowans case was resolved in September,
    2007.    Although the city paid the settlement in the Cowans case,
    it did not pay for Robinson's defense of McLaughlin.
    ii.    White's involvement in the Drumgold case.   White's
    involvement in the Drumgold litigation began in 2006, while he
    was a partner at DRW.     White represented two of the BPD officers
    named in the Drumgold case in succession -- a detective and then
    Lieutenant Timothy Callahan.
    Shawn Drumgold was convicted of murder in connection with
    the 1988 shooting death of a twelve year old girl.4     After
    Drumgold had been convicted and sentenced, he filed several
    motions for a new trial, seeking to have his conviction
    overturned on numerous grounds, including that members of the
    BPD had coerced witnesses into implicating him in the shooting.
    There also were claims that BPD officers failed to provide
    exculpatory evidence by not disclosing favorable treatment given
    to a prosecution witness.     The Commonwealth's assessment of the
    investigation concluded that Drumgold had not received a fair
    4
    The full factual background of that case is set forth in
    Commonwealth v. Drumgold, 
    423 Mass. 230
    , 233-235 (1996).
    8
    trial, and his conviction was vacated in 2003.
    In 2004, Drumgold filed the Federal civil rights lawsuit,
    claiming that the BPD officers involved in his investigation
    engaged in coercive tactics, pressured witnesses to give
    favorable testimony, and withheld exculpatory evidence, leading
    to Drumgold's erroneous conviction.   Drumgold also claimed that
    the BPD encouraged such conduct.   The city, as one of the named
    parties, retained its own counsel, but hired White to represent
    the detective in his individual capacity.   White was later hired
    to represent Callahan after the detective had been dismissed
    from the lawsuit.   The city had agreed to pay for the legal
    defense of the detective and Callahan pursuant to an
    indemnification agreement.   Although that agreement was not
    produced as part of Cousin's motion for a new trial, White
    testified that he had charged the city for his time representing
    the detective and Callahan on an hourly basis, at an agreed
    rate.   White would submit monthly bills to the city for its
    review and payment.   Over the course of White's representation
    of the detective and Callahan, the city paid White more than
    $310,000 for his work.   White testified that despite being
    compensated by the city for representing the detective and
    Callahan, he fully recognized that his only clients were the two
    officers, and his loyalty toward them was undivided.
    In January, 2008, the detective was dismissed from the
    9
    lawsuit.   Because White had been involved in discovery and the
    litigation in general, White testified that the city asked him
    to represent Callahan.   White filed his notice of appearance on
    behalf of Callahan on January 29, 2008.   Although White was
    listed as a lead attorney on the docket, he testified that he
    was not "asked to become the lead counsel for Callahan."    An
    attorney who had been the lead counsel representing Callahan
    maintained her position, and she assigned tasks to White.      When
    White began representing Callahan, he had already left DRW and
    was practicing at White & Associates.
    The judge noted that the course of the Drumgold litigation
    and the nature of the lawsuit indicated that the interests of
    the city and the individual defendants were aligned.   In the
    same way that the city had indemnified the individual defendants
    for their legal fees, the city also would be responsible for
    paying any judgment or settlement arising from the claims of
    misconduct against the individual officers.   The judge observed
    that even though the city had separate counsel, its liability
    was contingent on the liability of the individual defendants.
    Further, the judge noted that White had worked closely with the
    city while defending both the detective and Callahan, as evinced
    by the defendants' multiple joint filings and the conduct of the
    10
    litigation.5
    Concerning the structure and mechanics of the Drumgold
    trial, a judge in the United States District Court for the
    District of Massachusetts ordered that the trial be divided into
    three phases.   The first phase would address the liability of
    the individual officers, including Callahan.   The second phase
    would address the liability of the city and the BPD.   If the
    jury determined that there was a constitutional violation in
    either of the first two phases, then the third phase would
    address damages.   The first phase of the trial took place in
    March, 2008, where White participated in defending Callahan.
    The jury found that Callahan was liable for one of the civil
    rights claims against him, relating to his failure to disclose
    that he gave "substantial amounts" of money to a witness for the
    Commonwealth.   The parties then agreed to conduct the damages
    phase of the trial concerning the money Callahan had given to
    the witness, but the jury were unable to reach a verdict.    On
    March 31, 2009, the judge ordered a retrial that was
    specifically limited to Callahan's conduct regarding the
    witness, which was scheduled for September, 2009.6
    5
    In October, 2007, counsel for the respective defendants,
    including White, filed summary judgment motions on behalf of
    their clients.
    6
    The scope of BPD Lieutenant Timothy Callahan's retrial was
    limited to whether he intentionally or recklessly withheld
    11
    White did not participate in the Callahan retrial because,
    at that point, he was representing Cousin, whose criminal trial
    also was scheduled for September, 2009.    Although White did not
    participate in the Callahan retrial, he did not move to withdraw
    from the representation or otherwise remove himself from the
    case.    White testified that he was open to returning to
    represent Callahan if there was more work to be done on the
    Drumgold litigation after Cousin's case concluded.
    b.    White's representation of Cousin.   White was appointed
    to represent Cousin in 2008.    Davis, White's former law partner
    at DRW, had represented Cousin during his first trial.      After
    the appeal concerning Cousin's mistrial concluded, Davis
    withdrew as Cousin's counsel and recommended that White be
    appointed as successor counsel.7   White was no longer working at
    DRW at this time and he did not have a referral relationship
    with his former firm.    Cousin initially indicated that he
    intended to retain private counsel for his second trial, but
    after meeting White in the Nashua Street jail, Cousin agreed to
    evidence from prosecutors about "(1) the fact that [the witness]
    was housed at a hotel and provided with meals; (2) that there
    were promises of favorable treatment in [the witness's] pending
    criminal cases; and (3) that money was given to [the witness]."
    Drumgold v. Callahan, 
    806 F. Supp. 2d 405
    , 408 (D. Mass. 2011),
    overruled on another ground, 
    707 F.3d 28
    (1st Cir. 2013).
    7
    White testified that Davis's recommendation that he take
    over the Cousin's defense was spurred by a chance encounter
    between White and Davis, where they talked briefly about the
    case.
    12
    have White represent him.    Based on the testimony of White and
    Cousin at the hearing on the motion for a new trial regarding
    this meeting, the judge concluded that White did not provide
    sufficient information to Cousin about his representation of a
    police officer in the Drumgold case to allow Cousin to make an
    informed choice about choosing White as his attorney.
    Much of Cousin's claim that White was operating under an
    actual conflict of interest depended on the similarities he
    alleged between his case and the Drumgold and Cowans cases.
    The judge found that on June 29, 2002, the victim was shot
    and killed while playing at a park in the Roxbury section of
    Boston.   The perpetrator fired the fatal shot from a vehicle
    that was in the vicinity of the park.   Cousin's fingerprints
    were recovered from the exterior of that vehicle.    Additional
    fingerprints were also recovered from the vehicle.    Several of
    those fingerprints were individualized to two other individuals,
    including Cordell McAfee; other fingerprints were not initially
    matched to any individual.   The same fingerprint analyst who
    examined fingerprints in the Cowans case also examined the
    fingerprints recovered from the vehicle, and McLaughlin verified
    the reports that the analyst generated.    Shortly before Cousin's
    second trial, Rachel Lemery, another forensic examiner with the
    BPD latent fingerprint unit, reviewed those fingerprint reports.
    Based on her analysis of other fingerprints recovered from the
    13
    vehicle in 2002, Lemery was able to match those fingerprints to
    Daryl Richardson, a match that the previous analyst had failed
    to make before Cousin's first trial.8   It was likely that
    Richardson's fingerprint could have been matched in 2002,
    because Richardson was convicted of a crime in 1998, and thus
    his fingerprints were likely on file.
    The Richardson fingerprint match also is applicable to
    Cousin's claim that the lead detective in his case, Daniel
    Keeler, engaged in misconduct leading to Cousin's conviction.
    Specifically, Cousin contended that Keeler had used coercive
    techniques during his interrogation of Cordell McAfee, whose
    fingerprints had been found inside the vehicle and whose
    recorded statement implicated Cousin and his codefendant.      The
    issue with McAfee's recorded statement was that at least the
    first hour was not recorded, and Keeler did not take notes or
    generate a report summarizing the interview.   Further, at
    Cousin's first trial Keeler admitted that, prior to activating
    the recording device, McAfee had been shown certain photographic
    arrays that included photographs of Cousin and his codefendant
    and had not identified either individual.   Moreover, McAfee
    confessed that he had been in the vehicle during the shooting,
    8
    Rachel Lemery conducted a review of the fingerprints that
    the other analyst had analyzed and that McLaughlin had verified
    after the other analyst and McLaughlin had been removed from the
    BPD latent fingerprint unit.
    14
    along with two men named "Daryl" and "Man."   Cousin claimed that
    Keeler had coerced McAfee into changing his story while off tape
    and then recorded only McAfee's inculpatory statements.
    2.    Discussion.   We review the disposition of a motion for
    a new trial "to determine whether there has been a significant
    error of law or other abuse of discretion. . . . When, as here,
    the motion judge did not preside at trial, we defer to that
    judge's assessment of the credibility of witnesses at the
    hearing on the new trial motion, but we regard ourselves in as
    good a position as the motion judge to assess the trial record"
    (citations omitted).    Commonwealth v. Grace, 
    397 Mass. 303
    , 307
    (1986).   "While we will not disturb a judge's subsidiary
    findings which are warranted by the evidence, 'ultimate findings
    and conclusions of law, particularly those of constitutional
    dimensions, are open for our independent review.'"    Commonwealth
    v. Walter, 
    396 Mass. 549
    , 553-554 (1986), quoting Commonwealth
    v. Mahnke, 
    368 Mass. 662
    , 667 (1975), cert. denied, 
    425 U.S. 959
    (1976).
    a.    Actual conflict of interest.   The Commonwealth contends
    that the judge erred in concluding that White was burdened by an
    actual conflict of interest while representing Cousin.
    Specifically, the Commonwealth asserts that White's involvement
    in the Drumgold litigation and his former partner's
    representation of McLaughlin in the Cowans case, whether
    15
    considered in isolation or in the aggregate, did not amount to
    an actual conflict.   We agree.   Although Cousin identifies
    certain aspects of White's representation that are concerning,
    and may implicate a potential conflict of interest, Cousin has
    failed to meet his burden of adducing sufficient, nonspeculative
    evidence to establish that White was burdened by an actual
    conflict of interest.
    "Under the Sixth and Fourteenth Amendments to the
    Constitution of the United States and art. 12 of the Declaration
    of Rights of the Commonwealth, criminal defendants have a right
    to the assistance of counsel unimpaired by loyalties to other
    clients."   Commonwealth v. Mosher, 
    455 Mass. 811
    , 819 (2010),
    quoting Commonwealth v. Fogarty, 
    419 Mass. 456
    , 458 (1995).
    This bedrock constitutional guaranty "is intended to prevent a
    defendant's attorney from being hampered by contemporaneous
    divided loyalties or by having acquired privileged information
    which inhibits him in his representation of the defendant."
    Commonwealth v. Soffen, 
    377 Mass. 433
    , 437-438 (1979).    If a
    defendant establishes an actual conflict of interest under art.
    12, "he is entitled to a new trial without a further showing; he
    need not demonstrate that the conflict adversely affected his
    lawyer's performance or resulted in actual prejudice."    
    Mosher, 16 supra
    . See Commonwealth v. Hodge, 
    386 Mass. 165
    , 169-170 (1982).9
    No further showing is required because "the effect of the
    conflict on the attorney's representation of the defendant is
    likely to be pervasive and unpredictable, while the difficulty
    of proving it may be substantial, 'particularly as to things
    that may have been left not said or not done by counsel.'"
    
    Mosher, supra
    , quoting Hodge, supra at 170.
    An "actual" or "genuine" conflict of interest exists where
    the "independent professional judgment of trial counsel is
    impaired, either by his own interests, or by the interests of
    another client" (quotations omitted). Commonwealth v. Shraiar,
    
    397 Mass. 16
    , 20 (1986).   An actual conflict infects the
    defendant's representation to the point where "prejudice is
    'inherent in the situation,' such that no impartial observer
    could reasonably conclude that the attorney is able to serve the
    defendant with undivided loyalty."   
    Mosher, 455 Mass. at 819
    -
    820, quoting Commonwealth v. Epsom, 
    399 Mass. 254
    , 262 (1987).
    In determining whether such a conflict exists we look to the
    standards set forth in the applicable codes of professional
    ethics.   
    Mosher, supra
    at 820 n.19. See Mass. R. Prof. C. 1.7,
    9
    It is well established that art. 12 of the Massachusetts
    Declaration of Rights provides broader protection than the Sixth
    Amendment to the United States Constitution, which only entitles
    a defendant to a new trial if an actual conflict and prejudice
    is established. Compare Commonwealth v. Hodge, 
    386 Mass. 165
    ,
    169-170 (1982), with Cuyler v. Sullivan, 
    446 U.S. 335
    , 350
    (1980).
    17
    as appearing in 
    471 Mass. 1335
    (2015).10
    Given that representations marred by actual conflicts of
    interest exude the egregious and readily apparent divided
    loyalty of counsel, the circumstances where we have found an
    actual conflict have typically been limited to "[1] where an
    attorney represents codefendants with inconsistent or
    contradictory lines of defense; [2] where an attorney or an
    associate maintains an attorney-client or direct and close
    personal relationship with a material prosecution witness; or
    [3] where an attorney has business [or personal] reasons for
    preferring a verdict unfavorable to the defendant he or she
    represents."   
    Mosher, 455 Mass. at 820
    , quoting 
    Walter, 396 Mass. at 554-555
    .   Actual conflicts are present in these
    situations because they epitomize the facial repugnance of an
    attorney's divided loyalty, which places an unmistakable stain
    on the attorney-client relationship.    See 
    Mosher, supra
    at 819.
    These limited categories also stand in stark contrast to the
    multitude of situations that may give rise to a potential
    conflict of interest.   
    Id. at 823.
      Because a potential conflict
    of interest involves a more tenuous conflict, a defendant's
    conviction "will not be reversed except upon a showing of
    10
    In this opinion, we use the 2015 version of Massachusetts
    Rules of Professional Conduct, even though they were not in
    effect at the time the events at issue in this case took place,
    where changes to the rules are not material to our analysis.
    18
    material prejudice."    
    Shraiar, 397 Mass. at 20
    .
    The defendant carries the burden of proving both the
    existence and precise character of the alleged conflict of
    interest.   See 
    Walter, 396 Mass. at 554
    ; 
    Soffen, 377 Mass. at 437
    .    To satisfy this burden, we require "demonstrative proof
    detailing both the existence and the precise character of this
    alleged conflict of interest; we will not infer a conflict based
    on mere conjecture or speculation."    Commonwealth v. Stote, 
    456 Mass. 213
    , 218 (2010), quoting 
    Shraiar, 397 Mass. at 20
    .      We
    look to the attendant facts and circumstances surrounding the
    claimed actual conflict.   See Commonwealth v. Martinez, 
    425 Mass. 382
    , 392 (1997) (consideration of all facts concerning
    defendant's claim of conflict including attorney's relationship
    with prosecution witness, ethical problems, and undenied
    allegations of broken client confidence).    There is no
    substitute for meeting this burden other than sufficient,
    concrete evidence demonstrating an attorney's divided loyalty
    such that prejudice is inherent in the representation.     For this
    reason, we have never held that a defendant can establish an
    actual conflict of interest by cobbling together a collection of
    potential conflicts.    In determining whether an actual conflict
    exists, we do not consider potential conflicts in the aggregate,
    even in a representation plagued by potential conflicts; nor do
    we accept that potential conflicts have a synergistic effect
    19
    that can result in the creation of an actual conflict.
    The circumstances surrounding Cousin's claim that White had
    an actual conflict involve what appear to be, at first glance, a
    morass of factually similar cases, obscured connections between
    attorney-client relationships, and a thread of disturbing
    allegations of police misconduct.   Our review of the record
    reveals that these connections are in fact discretely
    compartmentalized aspects of unrelated cases.   Although the
    circumstances in this case, as they were developed at the
    hearing on the motion for a new trial, do not amount to an
    actual conflict, White's representation of Cousin nonetheless
    presents troubling issues that may constitute a potential
    conflict of interest.   However, we do not address the issue of a
    potential conflict because the only issue that was considered at
    the hearing on the motion for a new trial was whether there was
    an actual conflict.11
    b.   White's involvement in the Drumgold case.   The focal
    point of the judge's decision that White had an actual conflict
    was his involvement in the Drumgold civil rights lawsuit.      The
    judge construed White's involvement as embodying two problematic
    11
    On remand, there is an opportunity for additional
    evidentiary hearings to determine whether there was a potential
    conflict of interest, and whether Cousin was prejudiced thereby.
    20
    components: (1) White's overlapping representation of Callahan;12
    and (2) White's economic and personal interest in maintaining a
    professional relationship with the city, the entity that paid
    White's legal fees in the Drumgold case.     We review each issue
    in turn.
    i.    The Callahan representation.   The judge's conclusion
    that there was a substantial risk that White's loyalty may have
    been divided between Callahan and Cousin was based on her view
    that, "[t]o vigorously defend Cousin, White would necessarily
    have to take a position that was not in the interest of his
    client Callahan in the Drumgold [F]ederal suit . . . ."     This
    conclusion assumed that the Drumgold and Cousin cases were
    inextricably intertwined to the point where there were competing
    interests, such that White would be inhibited from zealously
    representing Cousin.
    As a threshold matter, in considering an alleged actual
    conflict stemming from an attorney's simultaneous representation
    of multiple clients who are not codefendants, the presence of an
    actual conflict has generally been limited to situations where
    the defendant's trial counsel simultaneously represents a
    prosecution witness who testifies against the defendant.     See
    12
    The claims against the detective in the Drumgold Federal
    civil rights lawsuit had been dismissed well before Cousin's
    second criminal trial. Therefore, the judge did not find, and
    Cousin does not argue, that White's prior representation of that
    detective created an actual conflict.
    21
    
    Mosher, 455 Mass. at 820
    , and cases cited.   In these
    circumstances, the conflict is clear; the prospect of defense
    counsel's cross-examination of a prosecution witness who is also
    counsel's client almost inevitably "inhibit[s] defense counsel
    from conducting vigorous cross-examination of the witness, or
    inhibit[s] defense counsel from pursuing certain avenues of
    inquiry through that witness, or tempt[s] counsel to disclose
    client confidences."   Commonwealth v. Patterson, 
    432 Mass. 767
    ,
    776 (2000), S.C., 
    445 Mass. 626
    (2005), overruled on another
    ground by Commonwealth v. Britt, 
    465 Mass. 87
    (2013).     In the
    present case, Callahan was neither involved in the investigation
    of Cousin nor called to testify as a prosecution witness at
    Cousin's trial.   In this respect, the alleged conflict
    concerning White's representation of Callahan in the Drumgold
    case falls well outside our established actual conflict
    paradigm.   See 
    Mosher, supra
    at 820.13
    Cousin endeavors to recast the circumstances of his case
    13
    In the context of a simultaneous representation:
    [W]e have found an actual conflict only where (1) at
    the time of trial, the defense attorney continued to
    represent a prosecution witness who furnished material
    testimony concerning a critical issue in the case against
    the defendant; or (2) the defense attorney had previously
    represented a prosecution witness in a matter related to
    the defendant's criminal case who furnished material
    testimony concerning a critical issue in the case against
    the defendant.
    Commonwealth v. Mosher, 
    455 Mass. 811
    , 820 (2010).
    22
    and the underlying criminal case in the Drumgold litigation to
    create the appearance that these cases are so interrelated that
    White's loyalty was inherently divided.   Cousin's argument is
    that White had an actual conflict in representing a BPD officer
    in the homicide division accused of police misconduct in the
    course of an investigation and, at the same time, representing a
    criminal defendant who sought to impugn the investigatory
    conduct of the BPD officers who investigated his case.     This
    proposition does not establish an actual conflict, although it
    may constitute a potential conflict.
    In analyzing Cousin's claim that White was saddled by a
    conflict of interest due to an overlapping representation, our
    analysis is aided by Mass. R. Prof. C. 1.7.   See 
    Mosher, 455 Mass. at 820
    n.19.   With limited exceptions, rule 1.7 prohibits
    an attorney from representing a client if the representation
    involves a concurrent conflict of interest.   A concurrent
    conflict of interest occurs where "(1) the representation of one
    client will be directly adverse to another client; or (2) there
    is a significant risk that the representation of one or more
    clients will be materially limited by the lawyer's
    responsibilities to another client, a former client or a third
    person or by a personal interest of the lawyer."     Mass. R. Prof.
    C. 1.7 (a) (1), (2).   Cousin does not contend, and the record
    does not indicate, that White's representation of Callahan was
    23
    directly adverse to Cousin.      Accordingly, we need only determine
    whether White's overlapping representations of Callahan and
    Cousin posed a significant risk that White would be materially
    limited in representing Cousin.     See Mass. R. Prof. C. 1.7 (a)
    (2).
    The concern reflected in Mass. R. Prof. C. 1.7 (a) (2) is
    that an attorney's duty to another client may materially limit
    the defendant's representation by inhibiting attorney's ability
    to "consider, recommend or carry out an appropriate course of
    action for the client."     Mass. R. Prof. C. 1.7 comment 8.     To
    determine whether there is a significant risk that the attorney
    is materially limited, "[t]he critical questions are the
    likelihood that a difference in interests will eventuate and, if
    it does, whether it will materially interfere with the lawyer's
    independent professional judgment in considering alternatives or
    foreclose courses of action that reasonably should be pursued on
    behalf of the client."     
    Id. An attorney
    may be materially
    limited "by having acquired privileged information which
    inhibits him in his representation of the defendant."         
    Soffen, 377 Mass. at 438
    .    See Mass. R. Prof. C. 1.7.
    The Drumgold and Cousin criminal cases involve the tragic
    shooting deaths of children.      The BPD homicide division
    investigated both cases.     Each case also involved claims of
    misconduct against the BPD officers who investigated the
    24
    killings, and both cases received significant media coverage.
    Described in these broad brush strokes, Cousin advances the
    judge's theory that a zealous representation of Cousin required
    an attack on the BPD homicide division, which was inconsistent
    with Callahan's interests, a BPD officer accused of misconduct
    in an unrelated civil case.   Under the lens with which we
    analyze the claimed actual conflict, however, the differences
    between the cases are significantly more telling than their
    apparent similarities.
    The record before this court establishes that Callahan was
    not involved in the investigation or prosecution of Cousin.
    Moreover, there is no connection between the allegations of
    police misconduct in those cases.   Cousin claims that Detective
    Keeler conducted a coercive interrogation of McAfee, the
    individual who eventually implicated Cousin in the shooting and,
    as detailed above, failed to reveal exculpatory evidence that
    McAfee provided.   Beyond Detective Keeler's conduct, Cousin also
    points to the analyst's failure to match fingerprints recovered
    from the vehicle to Richardson, and McLaughlin's verification of
    that faulty report.   The failure to originally individualize the
    fingerprints recovered from the vehicle to Richardson precluded
    Cousin from exploring a viable avenue in his defense.
    When White was representing Cousin at his retrial in
    September, 2009, the claims against Callahan in the Drumgold
    25
    case had been significantly narrowed.   A jury already had
    determined that Callahan was not liable for all civil rights
    claims other than failing to disclose exculpatory material
    concerning a key witness.   The Federal District Court judge
    limited the scope of the Callahan retrial to whether Callahan
    failed to disclose the fact that the witness was housed in a
    hotel and provided with meals, that there was promises of
    favorable treatment in the witness's pending criminal cases and
    that money was given to him.   Setting aside the fact that the
    Drumgold case and Cousin's criminal case were unrelated legal
    actions, Callahan was clearly not facing misconduct claims that
    remotely resembled Cousin's claims regarding Keeler.
    Because Cousin's case and the Drumgold case are
    unmistakably separate legal actions, involving different BPD
    officers investigating the killings, and distinguishable claims
    of police misconduct, a vigorous attack on the police conduct in
    Cousin's defense would not constitute an attack on all members
    of BPD's homicide unit.14   Moreover, Cousin has failed to produce
    14
    Were we to accept Cousin's premise, the natural
    implication would be a prohibition on attorneys representing a
    police officer in a civil case accused of misconduct and, at the
    same time, representing a criminal defendant who had been
    investigated by a different member of the same police
    department, even if the cases were unrelated and there was no
    connection between the officer-defendant in the civil case and
    the other members of that police department who investigated the
    defendant's case. This would be an overbroad and imprecise
    application of our conflict of interest law that would
    26
    any evidence from the record suggesting that vigorously
    defending Cousin would be inconsistent with representing
    Callahan.    We are further persuaded that, based on this record,
    White's representation of Callahan did not create an actual
    conflict of interest because there is no indication that White
    acquired confidential information from Callahan that materially
    limited his representation of Cousin.     See 
    Soffen, 377 Mass. at 437
    -438. See also Mass. R. Prof. C. 1.7.
    ii.     White's economic and personal interests.   The judge
    also concluded that White had an actual conflict of interest
    stemming from his economic and personal interest in the Drumgold
    litigation.    In the judge's view, "White had an economic or
    personal interest, at the time he represented Cousin, in
    remaining on good terms with the BPD, thus creating a
    substantial risk that the manner in which he represented Cousin
    could materially and adversely be affected."     Beyond White's
    financial compensation for his representation of the individual
    officers in the Drumgold case, the judge emphasized that, "[a]s
    the entity that paid the bills, the city was essentially White's
    largest paying client in the year leading up to Cousin's second
    trial."     On appeal, Cousin endorses this reasoning and further
    asserts that because the city was White's client, White was
    undoubtedly impact the law practice of many attorneys and limit
    the ability of police officers to hire the attorney of their
    choice.
    27
    restrained from vigorously challenging the investigation in his
    case because of his professional obligations to the city.
    Much like an actual conflict arising from the competing
    interests of clients, an attorney's own interests can impair his
    or her independent professional judgment to the point of causing
    an actual conflict.   See Commonwealth v. Perkins, 
    450 Mass. 834
    ,
    852 (2008); Mass. R. Prof. C. 1.7 (a) (2) & comment 1.    An
    attorney's personal interest can amount to an actual conflict of
    interest in a variety of situations.    See, e.g., 
    Hodge, 386 Mass. at 168
    (defense counsel's financial incentive "in not
    antagonizing his firm's client"); Commonwealth v. Crocken, 
    432 Mass. 266
    , 273 (2000) ("A lawyer's personal interests surely
    include his interest in maintaining amicable relations with his
    relatives, his spouse, and anyone with whom he is comparably
    intimate").   But see Commonwealth v. Milley, 
    67 Mass. App. Ct. 685
    , 689 (2006) (claim that attorney was complicit in hiring
    scheme to ensure he continued to receive appointments from
    clerk-magistrate was too speculative and did not show actual
    conflict with duty to represent defendant).
    In the context of an attorney's economic interest in a
    representation, we have held that an actual conflict exists
    "where an attorney has business reasons for preferring a verdict
    unfavorable to the defendant he or she represents" (citation
    omitted).   
    Mosher, 455 Mass. at 820
    .   However, an attorney's
    28
    financial interest in being compensated for providing legal
    representation, by itself, is generally too attenuated to
    constitute an actual conflict.   We have held that an actual
    conflict can materialize out of an attorney's financial interest
    in a representation combined with that attorney's duty of
    loyalty to another client or a third person.   For example, in
    
    Hodge, 386 Mass. at 168
    , trial counsel was burdened by an actual
    conflict where he was faced with cross-examining a prosecution
    witness who was, at that time, represented by that attorney's
    law firm.   We held that trial counsel was burdened by an actual
    conflict caused by his "financial interest in not antagonizing
    his firm's client by a vigorous cross-examination designed to
    discredit him, and his duty to consider only [the defendant's]
    best interest in deciding whether and how to cross-examine" the
    firm's client.   
    Id. The actual
    conflict in Hodge did not depend
    exclusively on trial counsel's financial interest in the
    representation, but the significant risk that his loyalty would
    be inherently divided in cross-examining his firm's client.      See
    
    id. Cousin has
    failed to adduce any facts to support his claim
    that White had an actual conflict because the city paid him to
    represent Callahan and the detective in the Drumgold case.     The
    fact that White was paid more than $310,000 for his
    representation, without more, does not provide a basis to
    29
    conclude that there was an actual conflict of interest.
    Furthermore, our conclusion is not altered by White's testimony
    indicating that he was open to returning to defend Callahan
    after Cousin's trial concluded, where this prospect, by itself,
    is also too speculative to conclude that White's personal
    interest caused him to have a divided loyalty, amounting to an
    actual conflict.   Although White's prospect of future work for
    the city would certainly be relevant in analyzing a potential
    conflict claim, without more it is too tangential to constitute
    an actual conflict.
    Cousin's claim that White had an actual conflict because
    the city was essentially his client is equally unsupported by
    the record.   Significantly, Cousin relies on speculation and
    conjecture to support his allegation that White was constrained
    from vigorously defending him through an attack on the alleged
    police misconduct in Cousin's defense because it could have
    exposed the BPD, and ultimately the city, to greater liability.15
    15
    Cousin contends that White admitted during the hearing on
    the motion for a new trial that he had a conflict of interest.
    This alleged acknowledgement occurred during an exchange between
    the judge and White, following White's testimony that he
    developed a practice of telling all of his criminal clients that
    he represented a police officer in the Drumgold case. The judge
    inquired, "Because it could be perceived as a conflict of
    interest?" White replied that "[i]t would certainly be
    perceived as a conflict of interest." The context of this
    exchange, in light of White's multiple repudiations about having
    an actual conflict, belie Cousin's contention that White
    conceded the existence of an actual conflict.
    30
    In search of support for this proposition, Cousin relies on
    United States v. Schwarz, 
    283 F.3d 76
    , 90-92 (2d Cir. 2002).
    Schwarz involved a police officer who had been charged with
    assault.   
    Id. at 80.
      In that case, the defendant's law firm had
    entered into a two-year, $10 million retainer agreement with the
    Policeman's Benevolent Association (PBA) to represent "all
    police officers in administrative, disciplinary, and criminal
    matters as well as to provide them with civil legal
    representation."   
    Id. at 81.
      The United States Court of Appeals
    for the Second Circuit determined that at the point the
    individual who had been assaulted filed a civil lawsuit against
    the PBA, an actual conflict arose because the PBA's interests
    diverged from those of the defendant.    
    Id. at 91.
      There was an
    actual conflict at that point because the PBA's interest in
    limiting its liability diverged from the defendant's interest in
    advancing a defense in which he would implicate another police
    officer in the assault.   
    Id. Defense counsel's
    zealous
    representation of the defendant in the criminal case could have
    hampered the PBA's defense in the civil suit and, as a result,
    the defendant's counsel faced an actual conflict between his
    representation of the defendant, on the one hand, and his
    professional obligation to the PBA as well as his own personal
    and financial interest on the other.    
    Id. at 91-92.
      Cf.
    Commonwealth v. Wooldridge, 
    19 Mass. App. Ct. 162
    , 167-168
    31
    (1985) (firm's contract with police association imposed
    continuing professional duties on firm's lawyers to former
    clients who were members of police association).
    The circumstances in Schwarz, particularly the existence of
    an agreement that the attorneys in Schwarz represented the PBA
    directly, highlight the infirmities in Cousin's claim that White
    had an actual conflict due to his relationship with the city.
    There is no indication that White represented the city, a police
    union, or anyone other than Murphy and Callahan in the Drumgold
    case.     Indeed, White testified at the hearing on the motion for
    a new trial that he only represented Murphy and Callahan in the
    Drumgold litigation.     Moreover, White testified that he
    understood his loyalty was exclusively to the detective and
    Callahan.16    Although White's agreement with the city to
    represent the individual officers was not produced at the
    hearing on the motion for a new trial, Cousin has failed to put
    forth evidence to controvert White's testimony that he only
    represented the detective and Callahan.     Contrast 
    Schwarz, 283 F.3d at 96
    (attorney's firm had $10 million retainer agreement
    with PBA to represent all police officers in variety of legal
    proceedings).
    16
    Although White's alleged personal interest in remaining
    on good terms with the city is certainly a relevant
    consideration in a potential conflict analysis, it is too
    ephemeral to amount to an actual conflict.
    32
    Similarly, there is no suggestion in the record that White
    or the city's conduct in the Drumgold case expanded the scope of
    White's representation beyond the detective and Callahan.17     The
    record is silent concerning what, if any, direction or control
    the city exerted over White in the course of his involvement in
    the Drumgold case.    Significantly, no information was developed
    concerning whether White had acquired confidential information
    about the city that may have been material to Cousin's defense,
    particularly his allegations of police misconduct.    Had White
    acquired confidential information about the city or the BPD that
    would have materially limited his representation of Cousin and
    created a concurrent conflict, that likely would have
    constituted an actual conflict.    See 
    Soffen, 377 Mass. at 437
    -
    438.    See also Mass. R. Prof. C. 1.7.   Although this may be a
    compelling avenue of exploration concerning a claim that there
    was a potential conflict, based on the record before this court,
    it does not amount to an actual conflict.     This conclusion
    applies equally to the premise that White may have been less
    17
    Cousin has failed to establish that there was an implied
    attorney-client relationship between White and the city. See
    Bays v. Theran, 
    418 Mass. 685
    , 690 (1994) ("attorney-client
    relationship may be implied when [1] a person seeks advice or
    assistance from an attorney, [2] the advice or assistance sought
    pertains to matters within the attorney's professional
    competence, and [3] the attorney expressly or impliedly agrees
    to give or actually gives the desired advice or assistance"
    [quotations and citation omitted]). Although the record before
    this court is undeveloped in this respect, it could be an area
    of relevant consideration in a potential conflict analysis.
    33
    than vigorous in defending Cousin because White wanted to
    maintain an amicable relationship with the city and not expose
    the city to greater liability in the Drumgold case.        It is clear
    from the dearth of information in the record that Cousin has
    failed to carry his burden of proving that White had an actual
    conflict as a result of his involvement in the Drumgold
    litigation or his relationship to the city.
    c.   Robinson's representation of McLaughlin.     In
    determining that White was burdened by an actual conflict, the
    judge considered, at least in part, Robinson's representation of
    McLaughlin, one of the fingerprint analysts in Cousin's case.
    Robinson defended McLaughlin, in the Cowans case, while White
    and Robinson were law partners at DRW, against a claim that
    McLaughlin had concealed an erroneous fingerprint match that had
    implicated Cowans in a shooting.   Cousin contends that White
    continued to owe a duty of loyalty to his former partner's past
    client that prohibited White from representing Cousin, thus
    amounting to an actual conflict.   We discern no such conflict.
    At the outset, it is uncontroverted that neither White nor
    Robinson was representing McLaughlin at the time of Cousin's
    trial.   Robinson's representation of McLaughlin ended in
    September, 2007, when the Cowans case settled.   White left DRW
    in 2007 and began his own firm, White & Associates.        He filed
    his notice of appearance on behalf of Cousin approximately one
    34
    year later, on October 22, 2008.   Significantly, McLaughlin was
    never identified as a witness for the Commonwealth and she did
    not testify at Cousin's first or second trials, which began in
    September, 2009.   White never confronted the prospect of cross-
    examining his former partner's past client in defending Cousin.
    Even were we to assume that McLaughlin may have testified
    as a prosecution witness against Cousin, despite her no longer
    being a member of the latent fingerprint unit, we have generally
    held that terminating that conflicting representation prior to
    the defendant's trial "obviat[es] the risk of simultaneous
    representation."   
    Martinez, 425 Mass. at 389
    .   Because
    Robinson's representation of McLaughlin ended approximately two
    years before Cousin's trial, White was not burdened by an actual
    conflict.   See 
    Mosher, 455 Mass. at 821-823
    (no actual conflict
    resulted from representation terminated one month prior to
    trial); 
    Patterson, 432 Mass. at 775-776
    (no actual conflict
    resulted from previously terminated representation); 
    Fogarty, 419 Mass. at 459-460
    (no conflict where defense counsel's
    associate ended representation of prosecution witness prior to
    defendant's retaining defense counsel); Commonwealth v. Smith,
    
    362 Mass. 782
    , 783-784 (1973) (no conflict where defense
    counsel's representation of prosecution witness ended before
    defendant's trial commenced).
    The fact that neither White nor Robinson was representing
    35
    McLaughlin at the time of Cousin's trial does not end our
    inquiry concerning whether White had a surviving duty of loyalty
    to McLaughlin that would have impeded him from vigorously
    representing Cousin.   To resolve this issue, we are guided by
    Mass. R. Prof. C. 1.9, as appearing in 
    471 Mass. 1359
    (2015),
    which traces the contours of an attorney's duty of loyalty to
    former clients.   Rule 1.9 prohibits an attorney from
    representing clients whose interests are adverse to a former
    client, particularly where that former client's confidential
    information may be at issue in the subsequent representation.
    See Mass. R. Prof. C. 1.9 (a).
    An attorney who leaves a law firm to take a position at
    another law firm may have a continuing duty of loyalty to his or
    her former firm's past clients.    Mass. R. Prof. C. 1.9 (b).
    That attorney is prohibited from representing a person in the
    same or a substantially related matter in which their former
    firm had represented a client where (1) that person's interests
    are materially adverse to the former client, and (2) the
    attorney acquired protected confidential information from the
    former client that is material to that person's case.    Mass. R.
    Prof. C. 1.9 (b) (1), (2).   This prohibition "operates to
    disqualify the lawyer only when the lawyer involved has actual
    knowledge of information protected by Rules 1.6 and 1.9(c)."
    Mass. R. Prof. C. 1.9 comment 5.    If the attorney did not
    36
    acquire knowledge about the former firm's client, and that
    attorney joins another firm, "neither the lawyer individually
    nor the second firm is disqualified from representing another
    client in the same or a related matter even though the interests
    of the two clients conflict."   
    Id. Although McLaughlin
    was a past client of White's prior law
    firm, White testified at the hearing on the motion for a new
    trial that he was uninvolved in Robinson's representation of
    McLaughlin, and he did not acquire any confidential information
    about McLaughlin.   There is nothing in the record that
    contradicts White's testimony that the partners at DRW generally
    handled their cases independently.    To the extent that White and
    his law partners at DRW discussed cases generally, the record is
    insufficiently developed to support an inference that general
    discussion about cases indicates that White acquired
    confidential information about McLaughlin from Robinson.18   There
    was no indication that White was restrained from challenging
    McLaughlin's work as a fingerprint analyst in Cousin's case.19
    18
    This type of informal discussion of cases, depending on
    their content and whether confidential information was
    discussed, would be a relevant inquiry in a potential conflict
    analysis.
    19
    The difference between the allegations of misconduct
    against McLaughlin in this case compared to the Cowans case is
    also significant. In the Cowans case, McLaughlin was accused of
    concealing the discovery that a fingerprint recovered from the
    crime scene was erroneously matched to Cowans, thus implicating
    37
    Furthermore, a telephone conversation that Robinson
    coordinated between White and McLaughlin does not change our
    view that there is insufficient evidence to establish an actual
    conflict on these grounds.   White testified that in the course
    of preparing for Cousin's trial, and in response to the report
    that the originally analyzed and unmatched fingerprints actually
    had a match, White attempted to contact McLaughlin.   Robinson
    facilitated the telephone call between White and McLaughlin
    after White mentioned, in the course of having lunch with
    Robinson, that he was preparing for Cousin's criminal trial and
    he had been unable to contact McLaughlin.   White spoke with
    McLaughlin in private, and Robinson was not present for the
    conversation.   Significantly, White testified that he did not
    acquire any confidential information about McLaughlin during
    that telephone call, and there is nothing in the record to
    indicate that White gleaned any confidential information during
    that conversation, which he described as brief and "not . . .
    terribly productive."   Accordingly, Cousin fails to set forth
    any information suggesting that White acquired confidential
    an apparently innocent individual in a crime. Here, the
    evidence indicates that McLaughlin verified another analyst's
    fingerprint analysis, in which that analyst evidently failed to
    individualize a latent print to an individual who was presumably
    in the fingerprint database. With no view on whether this
    constituted negligence, misconduct, or neither, it is
    nonetheless clear here that the allegations against McLaughlin
    in the two cases have no connection that would inhibit White
    from attacking McLaughlin's work in defending Cousin.
    38
    information, either before or during this telephone call, that
    triggers the prohibitions prescribed in rule 1.9 (b).    The mere
    fact that Robinson put White in contact with her former client
    in no way subverts that proposition.20
    3.   Conclusion.   Based on the foregoing, we discern that
    there was insufficient evidence to establish that White was
    burdened by an actual conflict.   We vacate the judge's decision
    granting Cousin's motion for a new trial and remand the case to
    the Superior Court for further evidentiary hearings on whether
    Cousin was prejudiced by potential conflicts of interest.
    So ordered.
    20
    The record is equally devoid of evidence that Robinson's
    representation of McLaughlin arose from an underlying,
    contractual referral relationship between the city or the Boston
    police patrolmen's union and Robinson and White. This is not
    altered by White's brief testimony indicating that Robinson knew
    the attorney for the patrolmen's union.
