    GANTS, C.J.   We once again confront the tragic legacy of
    the misconduct of Annie Dookhan when she was employed as a
    chemist at the William A. Hinton State Laboratory Institute
    (Hinton lab).   In Bridgeman v. District Attorney for the Suffolk
    Dist., 
    471 Mass. 465
    , 487 (2015) (Bridgeman I), the petitioners
    and the intervener, the Committee for Public Counsel Services
    (CPCS), asked that we exercise our broad powers of
    3
    superintendence to vacate the thousands of drug convictions
    affected by Dookhan's misconduct because the time and expense of
    case-by-case adjudication had become "untenable."    We declined
    at that time to adopt their proposed "global remedy."     However,
    the district attorneys have now provided the single justice with
    lists identifying more than 20,000 defendants who could be
    eligible for relief based on Dookhan's misconduct but who have
    not yet sought relief from their drug convictions.     As a result
    of the number of potentially aggrieved defendants, the single
    justice issued a reservation and report to the full court that
    essentially invites us to reconsider whether the time has come
    for a global remedy or whether further steps must be taken to
    realistically implement the remedy of case-by-case adjudication
    of potentially thousands of motions for a new trial.
    After such reconsideration, we decline to adopt the
    district attorneys' argument that we should stay the course we
    had previously set and take no further action to protect the
    rights of the "relevant Dookhan defendants."3   We also decline to
    adopt the petitioners' request for a global remedy in which we
    would either vacate the convictions of all relevant Dookhan
    defendants with prejudice, and thereby bar any reprosecution, or
    vacate the convictions without prejudice, and allow the
    3
    See note 8 and accompanying text, infra, for the
    definition of the term "relevant Dookhan defendants."
    4
    Commonwealth one year to reprosecute, dismissing with prejudice
    all cases not reprosecuted within that time period.
    We instead adopt a new protocol for case-by-case
    adjudication, which will occur in three phases, and order its
    implementation by the single justice in the form of a
    declaratory judgment.    In the first phase, the district
    attorneys shall exercise their prosecutorial discretion and
    reduce the number of relevant Dookhan defendants by moving to
    vacate and dismiss with prejudice all drug cases the district
    attorneys would not or could not reprosecute if a new trial were
    ordered.    In the second phase, new, adequate notice shall be
    approved by the single justice and provided to all relevant
    Dookhan defendants whose cases have not been dismissed in phase
    one.    In the third phase, CPCS shall assign counsel to all
    indigent relevant Dookhan defendants who wish to explore the
    possibility of moving to vacate their plea or for a new trial.
    If the number seeking counsel is so large that counsel cannot be
    assigned despite CPCS's best efforts, the single justice will
    fashion an appropriate remedy under our general superintendence
    authority for the constitutional violation, which may include
    dismissing without prejudice the relevant drug convictions in
    cases where an indigent defendant is deprived of the right to
    counsel.
    5
    We recognize that the implementation of this protocol will
    substantially burden the district attorneys, CPCS, and the
    courts.   But we also recognize that Dookhan's misconduct at the
    Hinton lab has substantially burdened the due process rights of
    many thousands of defendants whose convictions rested on her
    tainted drug analysis and who, even if they have served their
    sentences, continue to suffer the collateral consequences
    arising from those convictions.   And we recognize as well that,
    more than four years after Dookhan's misconduct was revealed,
    more than 20,000 defendants who are entitled to a conclusive
    presumption that egregious government misconduct occurred in
    their case have yet to receive adequate notice that they may
    have been victimized by Dookhan's misconduct, that they may file
    a motion to vacate their drug conviction, and that they have a
    right to counsel to assist them in the preparation of such a
    motion.   The remedy we order, challenging as it is to implement,
    preserves the ability of these defendants to vindicate their
    rights through case-by-case adjudication, respects the exercise
    of prosecutorial discretion, and maintains the fairness and
    integrity of our criminal justice system in the wake of a
    laboratory scandal of unprecedented magnitude.4

    6
    Background.     Dookhan began her employment in November,
    2003, as a chemist at the Hinton lab, a forensic drug laboratory
    that was overseen by the Department of Public Health
    (department).    See Commonwealth v. Scott, 
    467 Mass. 336
    , 338
    (2014); Commonwealth v. Charles, 
    466 Mass. 63
    , 64 (2013).
    Allegations of misconduct regarding her work surfaced in June,
    2011, which triggered an internal review and then a formal
    internal investigation by the department in December, 2011.
    Charles, supra.      The department concluded that "Dookhan failed
    to follow [Hinton lab] protocols for the transfer and
    documentation of samples for testing, and subsequently created a
    false record of said transfers."       Id.    Dookhan was placed on
    paid administrative leave and then resigned from her position,
    effective March 9, 2012.       Id.
    In July, 2012, the Legislature transferred oversight of the
    Hinton lab to the State police.      See St. 2012, c. 139, § 56
    (replacing G. L. c. 22C, § 39); St. 2012, c. 139, § 107
    (repealing G. L. c. 111, §§ 12-13).          See also Scott, 
    467 Mass. 338
    .    In August, 2012, the State police initiated a more
    extensive investigation of the Hinton lab, which "revealed
    numerous improprieties surrounding Dookhan's conduct in the
    lab."    Id. at 339.    See Charles, 466 Mass. at 64.      Based in part
    the New England Innocence Project and the North Carolina Center
    on Actual Innocence.
    7
    on Dookhan's confession of misconduct on August 28, 2012, the
    State police investigation revealed, among other misconduct, the
    following:
       Dookhan "admitted to 'dry labbing' for two to three years
    prior to her transfer out of the [Hinton] lab in 2011,
    meaning that she would group multiple samples together from
    various cases that looked alike, then test only a few
    samples, but report the results as if she had tested each
    sample individually." Scott, supra.
       She admitted to "contaminating samples intentionally,
    including turning negative samples into positive samples on
    at least a few occasions." Id.
       She admitted that she removed samples from the evidence
    locker in breach of Hinton lab protocols, postdated entries
    in the evidence log book, and forged an evidence officer's
    initials. Id.
       She falsified reports intended to verify that the gas
    chromatography-mass spectrometer machine used in
    "confirmatory"5 drug testing was functioning properly before
    she ran samples through the machine. Id. at 339-340.
       The potential scope of Dookhan's misconduct encompassed
    testing samples in over 40,000 cases. Id. at 340. This
    number is so large because Dookhan "reported test results
    5
    "Confirmatory" testing is often referred to in our
    opinions as "secondary" testing. We use the terms
    interchangeably.
    8
    on samples at rates consistently much higher than any other
    chemist in the [Hinton] lab." Id.6
    A grand jury indicted Dookhan on seventeen counts of
    tampering with evidence, eight counts of obstruction of justice,
    one count of perjury, and one count of falsely claiming to hold
    a graduate degree.   Dookhan pleaded guilty to all of the
    indictments on November 22, 2013, and she was sentenced to from
    three years to five years in State prison, followed by a
    probationary term of two years.   Scott, 467 Mass. at 337 & n.3.
    The revelations regarding Dookhan's misconduct triggered the
    filing of hundreds of motions for a new trial and for a stay of
    execution of sentence in cases where the defendant was convicted
    6
    In addition to the State police investigation, the
    Governor requested a top-to-bottom review of the William A.
    Hinton State Laboratory Institute (Hinton lab) to determine
    whether any other employees at the Hinton lab committed
    malfeasance. The office of the Inspector General (OIG)
    conducted a fifteen-month investigation of the Hinton lab that
    included interviews with more than forty individuals and an
    examination of more than 200,000 documents. The OIG concluded
    that "Dookhan was the sole bad actor at the [Hinton lab]" and
    that no other chemist at the laboratory knowingly aided her
    misconduct. But the OIG report described massive deficiencies
    by the Department of Public Health (department) in its oversight
    and management of the Hinton lab. These deficiencies included a
    lack of accreditation and inadequate chemist training; distant
    or uninterested supervisors; inconsistent testing practices;
    deviation from chain-of-custody guidelines; and faulty security.
    This environment "gave Dookhan the freedom to start making and
    following her own rules." Even when coworkers began raising red
    flags about Dookhan, directors at the Hinton lab were
    "habitually unresponsive" and "severely downplayed Dookhan's
    major breach in chain-of-custody protocol." The OIG report
    concluded that "all samples in which Dookhan was the primary
    chemist should be treated as suspect and be subject to careful
    review."

    of a drug crime based on a drug analysis conducted by the Hinton
    lab.       Charles, 466 Mass. at 65-66.7   To address this onslaught of
    motions, the Chief Justice of the Superior Court in October,
    2012, assigned specific judges in seven counties to preside over
    special "drug lab" sessions.       Id. at 65.   To assist these judges
    in the adjudication of these cases, the Chief Justice of the
    Superior Court in November, 2012, exercised her authority under
    Mass. R. Crim. P. 47, 
    378 Mass. 923
     (1979), to appoint five
    retired Superior Court judges as "Special Judicial Magistrates
    of the Superior Court" to preside over postconviction motions
    related to the Hinton lab.       Id. at 66.
    In Scott, 467 Mass. at 337-338, we considered the
    appropriate legal standard where a defendant, in response to
    government misconduct in his or her case, moves to withdraw a
    7
    These motions were facilitated by a special task force
    established by the Governor in September, 2012. The task force,
    led by attorney David Meier, used data from the department to
    identify individuals who could have been affected by Dookhan's
    misconduct. The task force then shared the lists with
    prosecutors, defense attorneys, and judges, "so as to enable
    each of the agencies and offices to respond appropriately." The
    task force concentrated on identifying individuals most
    adversely affected, such as those in custody, awaiting trial, or
    on probation or parole. By December, 2012, the task force
    identified approximately 10,000 individuals who fell in these
    priority categories and who had to be notified immediately that
    their cases potentially were affected by Dookhan's misconduct.
    The task force also produced a more comprehensive list of
    approximately 40,000 cases in which Dookhan served as a primary
    or confirmatory chemist. At the time the task force completed
    its final report, the criminal investigation of Dookhan and the
    OIG's review of the Hinton lab were still ongoing.

    guilty plea or an admission to sufficient facts to warrant a
    finding of guilty.   We adopted the two-pronged test in Ferrara
    v. United States, 
    456 F.3d 278
    , 290 (1st Cir. 2006), which
    requires a defendant who seeks to vacate a guilty plea because
    of government misconduct to show "both that 'egregiously
    impermissible conduct . . . by government agents . . . antedated
    the entry of his plea' and that 'the misconduct influenced his
    decision to plead guilty or, put another way, that it was
    material to that choice.'"   Scott, supra at 346.
    In considering whether the defendant had satisfied the
    first prong of this test, we concluded that, because Dookhan
    "made a number of affirmative misrepresentations by signing
    [certificates of drug analysis (drug certificates)] and
    testifying to the identity of substances in cases in which she
    had not in fact properly tested the substances in question,"
    Dookhan's misconduct was "egregious."   Id. at 348.   We also
    concluded that, even though there was no indication that any
    prosecutor knew of her egregious misconduct, id. at 350 n.7, her
    misconduct is "attributable to the government" for purposes of a
    motion for a new trial, id. at 350 & n.7, because as a primary
    and secondary chemist she "participated in the investigation or
    evaluation of the case" and "reported to the prosecutor's office
    concerning the case."   Id. at 349, quoting Commonwealth v.
    Martin, 
    427 Mass. 816
    , 824 (1998).
    11
    We also recognized the dilemma that a defendant would face
    in attempting to prove that the laboratory analysis in his or
    her case was tainted by Dookhan's misconduct.      See Scott, 467
    Mass. at 339, 351-352.    We noted that Dookhan acknowledged "that
    she may not be able to identify those cases in which she tested
    the samples properly and those in which she did not."      Id. at
    339.    "Thus, even if Dookhan herself were to testify in each of
    the thousands of cases in which she served as primary or
    secondary chemist, it is unlikely that her testimony, even if
    truthful, could resolve the question whether she engaged in
    misconduct in a particular case."    Id. at 352.   Because it was
    "reasonably certain . . . that her misconduct touched a great
    number of cases," id., but "may be impossible" for any defendant
    to prove that the drug analysis in his or her case was tainted
    by her misconduct, id. at 351, we recognized that her
    "particularly insidious form of misconduct, which belies
    reconstruction," resulted in "a lapse of systemic magnitude in
    the criminal justice system."    Id. at 352.
    To resolve this dilemma, we exercised our power of "general
    superintendence of all courts . . . to correct and prevent
    errors and abuses" under G. L. c. 211, § 3, and held that, where
    Dookhan signed the drug certificate in a defendant's case as an
    assistant analyst, that is, as the primary or confirmatory
    chemist, see Scott, 467 Mass. at 353 n.9, a defendant who seeks
    12
    to vacate his or her plea after learning of Dookhan's misconduct
    "is entitled to a conclusive presumption that egregious
    government misconduct occurred in [his or her] case."         Id. at
    352.   The consequence of the conclusive presumption of egregious
    government misconduct is that a defendant can satisfy the first
    prong of the Ferrara test simply by showing that Dookhan signed
    the drug certificate in his or her case as an assistant analyst.
    Id. at 353.
    We emphasized in Scott that the "special evidentiary rule"
    of a conclusive presumption is "sui generis" -- "a remedy
    dictated by the particular circumstances surrounding Dookhan's
    misconduct" that was "intended to apply only to this narrow
    class of cases in which a defendant seeks to withdraw his or her
    guilty plea after having learned of Dookhan's misconduct."         Id.
    at 353-354.   We declared that "it is most appropriate that the
    benefit of our remedy inure to defendants" where, as here, there
    is "government misconduct that has cast a shadow over the entire
    criminal justice system."    Id. at 352.    The remedy of a
    conclusive presumption, we concluded, takes into account "the
    due process rights of defendants, the integrity of the criminal
    justice system, the efficient administration of justice in
    responding to such potentially broad-ranging misconduct, and the
    myriad public interests at stake."    Id.
    13
    We did not relieve a defendant of the burden to satisfy the
    second prong of the Ferrara test by demonstrating that he or she
    suffered prejudice by pleading guilty or admitting to sufficient
    facts without having learned of Dookhan's misconduct, i.e., we
    did not conclusively presume such prejudice.     Id. at 354-355,
    356.    The defendant, therefore, bears the burden of proving "a
    reasonable probability that he [or she] would not have pleaded
    guilty had he [or she] known of Dookhan's misconduct," and
    instead would have chosen to go to trial.    Id. at 355.   We noted
    that, "[u]nlike evidence of the particular scope of Dookhan's
    misconduct, evidence of the circumstances surrounding the
    defendant's decision to tender a guilty plea should be well
    within the defendant's reach."    Id. at 354 n.11.
    In Commonwealth v. Francis, 
    474 Mass. 816
     (2016), we
    reviewed the denial of a defendant's motion for a new trial
    where the defendant had been convicted at trial of drug charges
    after drug certificates were admitted in evidence that were
    signed by Dookhan as an assistant analyst.     We concluded that
    the conclusive presumption of "egregious government misconduct"
    is not limited to motions to withdraw guilty pleas, but that,
    where the defendant has been convicted at trial, "[t]he
    consequence of the conclusive presumption is that we deem it
    error to have admitted the drug certificates or comparable
    evidence regarding Dookhan's drug analysis where the defendant
    14
    had no knowledge of Dookhan's misconduct and therefore no
    opportunity to challenge the admissibility or credibility of
    that evidence."   Id. at 817.
    In Commonwealth v. Ruffin, 
    475 Mass. 1003
    , 1003-1004
    (2016), we declined to apply the conclusive presumption of
    "egregious government misconduct" where the defendant had
    pleaded guilty before Dookhan had signed the drug certificate as
    an assistant analyst, because her misconduct cannot be said to
    have affected the defendant's plea where the plea occurred
    before the misconduct.
    Consequently, after our opinions in Scott, Francis, and
    Ruffin, the defendants who are entitled to the conclusive
    presumption of "egregious government misconduct" are those who
    pleaded guilty to a drug charge (or admitted to sufficient facts
    to warrant a finding of guilty) or who were found guilty of a
    drug charge at trial after Dookhan signed a drug certificate in
    15
    their case as a primary or confirmatory chemist.   We refer to
    these as the "relevant Dookhan defendants."8
    In Bridgeman I, 471 Mass. at 473-494, we considered two
    sets of issues raised by relevant Dookhan defendants who
    potentially were eligible for relief from their convictions
    because of Dookhan's misconduct, but who had not yet moved for
    postconviction relief.   The first set of issues identified
    concerns that were discouraging these defendants from seeking
    that relief.   The most significant was the risk that, if their
    motion for a new trial were granted, the Commonwealth could
    reprosecute them not only on the charge to which the defendants
    had pleaded guilty but also on any charge that was dismissed at
    the time of the plea, and seek a more severe sentence,
    especially where the dismissed charge carried a mandatory
    minimum sentence upon conviction.   Id. at 472-473.   Drawing
    8
    The term "Dookhan defendants" was defined in Bridgeman v.
    District Attorney for the Suffolk Dist., 
    471 Mass. 465
    , 467 n.4
    (2015) (Bridgeman I), "to refer generally to those individuals
    who were convicted of drug offenses and in whose cases Dookhan
    signed the certificate of drug analysis (drug certificate) on
    the line labeled 'Assistant Analyst.'" Because Bridgeman I was
    decided before Commonwealth v. Ruffin, 
    475 Mass. 1003
     (2016),
    the term "Dookhan defendants" is broader than the term "relevant
    Dookhan defendants," because it includes those with cases in
    which Dookhan signed the drug certificate after their guilty
    plea or admission to sufficient facts to warrant a guilty
    finding. In light of our decision in Ruffin, the set of
    defendants entitled to the conclusive presumption of egregious
    government misconduct is limited to the "relevant Dookhan
    defendants," and the relief we order infra is limited to this
    set of defendants.
    16
    broadly on the need to "ameliorate [the] damaging effects" of
    Dookhan's misconduct, 
    id. at 474
    , we held that "a defendant who
    has been granted a new trial based on Dookhan's misconduct at
    the Hinton . . . lab cannot be charged with a more serious
    offense than that of which he or she initially was convicted
    under the terms of a plea agreement and, if convicted again,
    cannot be given a more severe sentence than that which
    originally was imposed."   
    Id. at 468
    .
    The second set of issues in Bridgeman I concerned the
    fairness and practicability of attempting individually to
    resolve the multitude of motions for a new trial that
    potentially could be brought by the Dookhan defendants.    We
    allowed the motion to intervene filed by CPCS under Mass. R.
    Civ. P. 24 (a), 
    365 Mass. 769
     (1974), recognizing that "[i]t has
    a substantial and immediate interest in these proceedings given
    its current and future responsibility for providing
    representation to thousands of indigent Dookhan defendants who
    want to pursue postconviction relief from their drug
    convictions."   Bridgeman I, 471 Mass. at 485-486.    We then
    addressed CPCS's contention that, because so many cases were
    affected by Dookhan's misconduct, the "time and expense of
    proceeding on a case-by-case basis has become untenable," and we
    therefore should implement a "global remedy" to resolve these
    cases pursuant to our broad powers of superintendence under
    17
    G. L. c. 211, § 3.      Bridgeman I, supra at 487.     Under the global
    remedy that CPCS proposed, we would vacate the convictions of
    all Dookhan defendants.      Id.    CPCS offered two alternatives:   we
    could vacate the convictions with prejudice, and thereby bar any
    reprosecution; or we could vacate the convictions without
    prejudice, and allow the Commonwealth one year to reprosecute,
    dismissing with prejudice all cases not reprosecuted within that
    time period.    Id.
    We declined in Bridgeman I to implement a global remedy "at
    this time."    Id.    We noted that "while '[i]t certainly is true
    that we cannot expect defendants to bear the burden of a
    systemic lapse, . . . we also cannot allow the misconduct of one
    person to dictate an abrupt retreat from the fundamentals of our
    criminal justice system.'"         Id., quoting Scott, 467 Mass. at 354
    n.11.    We also noted that we had already provided "meaningful
    solutions" to resolve these cases in Scott and Charles, and
    that, in Bridgeman I, we were removing the barriers that made
    defendants reluctant to file motions to withdraw their guilty
    pleas.    Id. at 480, 487.   And we noted that some district
    attorneys had made progress in providing CPCS with the docket
    numbers of the cases in which Dookhan was the primary or
    confirmatory chemist, and encouraged the remaining district
    attorneys with such cases to assist the single justice in
    18
    obtaining docket numbers for their districts.9    Id. at 481.   We
    recognized that "efforts to provide postconviction relief to
    Dookhan defendants [had] been hampered by the inability of CPCS
    to ascertain which cases may have been tainted by Dookhan's
    misconduct," and that "[t]he ability of CPCS to identify clients
    and to assign them attorneys who will represent their interests
    in postconviction proceedings is crucial to the administration
    of justice in the Hinton . . . lab cases."   Id. at 480.   We
    remanded the case to the single justice for further proceedings
    consistent with the opinion.   Id. at 494.
    The single justice joined as respondents the district
    attorneys for the Cape and Islands, Middlesex, Norfolk, and
    Plymouth districts, and allowed the motion of the district
    attorney for the Bristol district to intervene.    The single
    justice ordered the district attorneys to produce lists with the
    names, docket numbers, and personal identifying information for
    every "adverse disposition concerning every G. L. c. 94C charge"
    9
    Only the district attorneys for the Suffolk and Essex
    districts were parties to Bridgeman I, 471 Mass. at 481. They
    provided CPCS with the relevant docket numbers in their
    districts in September, 2014. Id. at 478 n.20. The district
    attorneys for the Bristol and Norfolk districts later provided
    CPCS with the relevant docket numbers before the issuance of the
    opinion in Bridgeman I. Id. The district attorneys for the
    Cape and Islands, Middlesex, and Plymouth districts had yet to
    do so at the time that opinion issued. Id.
    19
    of the "Dookhan defendants."10   In May, 2016, the district
    attorneys produced lists that contained the names of more than
    20,000 defendants with more than 24,000 cases where they had
    pleaded guilty to a drug charge, had admitted to sufficient
    facts to warrant a finding of guilty of a drug charge, or had
    been found guilty at trial of a drug charge where Dookhan had
    tested the alleged drugs as the primary or confirmatory
    chemist.11
    10
    Because the list encompasses the "Dookhan defendants," it
    includes some defendants who are not "relevant Dookhan
    defendants." See note 8 and accompanying text, supra.
    11
    The lists were the product of the commendable and
    laborious efforts of the Trial Court's information technology
    department, which identified the set of all cases with a G. L.
    c. 94C charge from 2003 to June, 2011, and of the district
    attorneys' offices, which then identified the subset of these
    cases where Dookhan was the primary or confirmatory chemist.
    The district attorneys state that they have identified
    approximately 20,544 defendants in 24,577 cases that featured at
    least some evidence tested by Dookhan and that resulted in an
    adverse consequence. The CPCS data analyst identified 24,391
    cases in which defendants still face adverse dispositions on
    drug charges where Dookhan was the primary or confirmatory
    chemist. Both parties contend that the respective tallies are
    not a perfect measure of the remaining pool of cases tainted by
    Dookhan's misconduct. As earlier stated, these lists include
    defendants who are not relevant Dookhan defendants because they
    pleaded guilty or admitted to sufficient facts before Dookhan
    signed the drug certificate as an assistant analyst. The
    district attorneys claim that, apart from including the so-
    called Ruffin defendants, the lists overcount the number of
    relevant Dookhan defendants because they include some defendants
    who already moved to vacate their pleas, and because they
    include defendants who were codefendants in a case where Dookhan
    was an assistant analyst. The Bridgeman petitioners and CPCS
    claim that the lists actually undercount the number of remaining
    defendants because of errors in the district attorneys' data.
    20
    The single justice also asked the parties to attempt to
    agree on the content of a letter of notice to the Dookhan
    defendants informing them that their drug cases had been
    potentially tainted by Dookhan's misconduct.   After the
    submission of the lists, however, the Bridgeman petitioners and
    CPCS12 would not agree to any notice that presumed case-by-case
    litigation, because they contended that, given the large number
    of Dookhan defendants and the limited resources of CPCS, the
    notice could not truthfully inform the Dookhan defendants that
    attorneys were available to represent them in these cases.    They
    asked the single justice to reserve and report to the full court
    the question "whether all cases involving misconduct by Annie
    Dookhan should be dismissed or subjected to a court-ordered
    deadline."   The district attorneys opposed the reservation and
    report, arguing that the notices would provide all Dookhan
    defendants the opportunity to seek relief.   They also contended
    We need not resolve these differences and ascertain the precise
    number of relevant Dookhan defendants because, even if we were
    to adopt the district attorneys' estimates, there would still be
    close to 20,000 relevant Dookhan defendants who might be
    entitled to postconviction relief.
    12
    For the sake of simplicity, we will refer to both the
    Bridgeman I petitioners and CPCS as the "Bridgeman petitioners"
    for the remainder of this opinion, even though we recognize that
    CPCS is an intervener rather than a petitioner in this case. We
    refer to the "Bridgeman petitioners" because this is a civil
    case seeking declaratory relief, even though we recognize that
    the Bridgeman petitioners are each Dookhan defendants in
    criminal cases.
    21
    that the Bridgeman petitioners "significantly overstate[] the
    apparent degree of interest on the part of the Dookhan
    defendants in revisiting settled cases."    The single justice
    issued a reservation and report on August 16, 2016.
    The district attorneys advised the single justice before
    the issuance of the reservation and report that they intended to
    send notices regardless of whether the case was reported to the
    full court.   On August 29, 2016, the district attorneys filed in
    the county court a letter attaching the notice they intended to
    send on or before September 1.    The Bridgeman petitioners
    informed the district attorneys that the notice was misleading
    and poorly translated.     At a hearing on September 6, the single
    justice invited the district attorneys to delay sending the
    notice, but the district attorneys announced that the mailing
    had already begun.   On September 7, CPCS filed an emergency
    motion asking the full court to halt further dissemination of
    the notice; the court denied the motion but ordered the district
    attorneys to keep records of all documents and communications
    arising from the notice.
    The notice was mailed in an envelope with the return
    address of "RG/2 Claims Administration LLC," and a post office
    box in Philadelphia, Pennsylvania, along with the words
    "IMPORTANT LEGAL NOTICE FROM THE COMMONWEALTH OF MASSACHUSETTS"
    22
    near the return address.13    The notice informed each defendant
    that, according to court records, he or she was convicted of one
    or more drug offenses in a specified county between 2003 and
    2011; that it has been determined that Dookhan tested the drugs
    in the case; and that Dookhan "admitted to misconduct in her
    work at the [Hinton] lab."    It advised the defendant that,
    because Dookhan tested the evidence, he or she has certain
    rights, specifically, "the right to challenge the drug
    conviction(s) listed in this notice" and that "if [the defendant
    is] tried and convicted again, [he or she] will not face any
    punishment greater than what [he or she] already received."    The
    notice asked the defendant to contact his or her original lawyer
    on the case if he or she has any questions, and also invited the
    defendant to speak with a new lawyer.    The notice further
    invited the defendant, should he or she not know how to contact
    the original lawyer, to get that information at the criminal
    clerk's office where the case was adjudicated, and provided the
    Web site address where the physical address of the relevant
    court can be found.14
    13
    RG/2 Claims Administration, LLC, is the vendor who
    contracted with the district attorneys to distribute the notice.
    14
    The full English text of the notice is reprinted below:
    "Dear [recipient]:
    23
    A Spanish translation of the notice was included on the
    bottom of the page.     According to the Bridgeman petitioners,
    this translation "contained numerous errors and was not readily
    understandable to a person who speaks Spanish but not English."15
    "According to court records, you were convicted of one or
    more drug offenses in the [county] between 2003 and 2011.
    It has been determined that chemist Annie Dookhan tested
    the drugs in your case(s), [court name], [docket number]
    "Ms. Dookhan admitted to misconduct in her work at the
    [Hinton] lab. Because Ms. Dookhan tested evidence in your
    case, you have certain rights:
    "• You have the right to challenge the drug conviction(s)
    listed in this notice. If your challenge succeeds,
    your conviction(s) will be undone or 'vacated,' and
    your case will be returned to active status.
    "• The District Attorney's office may decide to try you
    again on the vacated drug charge(s), but if you are
    tried and convicted again, you will not face any
    punishment greater than what you already received. In
    other words, you cannot be additionally punished for
    choosing to challenge your conviction(s).
    "If you have any questions, please contact your original
    lawyer on your case(s). You may also choose to speak to a
    new lawyer. If you do not know how to contact your
    original lawyer, you may get that information at the
    criminal clerk's office at the court where your case was
    handled. Addresses for all of the District and Superior
    courts can be found at [State government Web site].
    "For more information, you may contact the [district
    attorney's office]."
    15
    The Bridgeman petitioners included in the record an
    affidavit from Michael W. O'Laughlin, a qualified Spanish
    interpreter, who attested that "the Spanish translation
    contained within [the notice letter] is not accurate or clear."
    He identified various flagrant errors in the translation of the
    notice, including the following:
    24
    The district attorneys have not offered any evidence to rebut
    these claims or to defend the quality of the translation.
    The district attorneys' vendor mailed 20,916 letters to
    Dookhan defendants.16   The vendor was unable to locate the
    addresses for 1,006 defendants, and 5,767 of the letters that
    were sent were returned undelivered.   For those letters returned
    undelivered, the vendor searched for a secondary address and
    sent out an additional 964 notices.    As of October 24, 2016, the
    over-all response rate to these mailings was extremely low:
       In the Bristol district, where approximately 2,200 cases
    were identified, the district attorney received thirty-nine
    telephone calls and three motions were filed.
       In the Cape and Islands district, where approximately 1,300
    cases were identified, the district attorney received
    thirty-nine calls and one walk-in inquiry. No motions were
    filed.
       In the Essex district, where approximately 4,200 cases were
    identified, the district attorney received forty-six
    telephone calls and twelve walk-in inquiries. Seven
    motions were filed.
       The word "vacated" was translated in the notice as
    "desocupar," meaning to physically vacate premises, not to
    vacate a judicial decision.
       The verb tense in the same sentence was changed so that it
    appeared that a successful motion may yield only the
    possibility that the conviction would be vacated.
       The translation of "criminal clerk's office" described a
    clerk who is himself also a violent felon.
    O'Laughlin also described the translation of a crucial sentence
    in the notice explaining the district attorney's ability to
    retry the recipient's case as "unintelligible."
    16
    Because some defendants had cases in multiple counties,
    the number of letters that were mailed exceeded the number of
    defendants identified in the lists.
    25
       In the Middlesex district, where approximately 3,500 cases
    were identified, the district attorney received seventy-
    seven telephone calls and seven walk-in inquiries. Two
    motions were filed.
       In the Norfolk district, where approximately 2,300 cases
    were identified, the district attorney received
    approximately one hundred inquiries. Seven motions were
    filed.
       In the Plymouth district, where approximately 2,000 cases
    were identified, the district attorney received sixty-five
    inquiries, including three walk-ins. One motion was filed.
       In the Suffolk district, where approximately 8,600 cases
    were identified, the district attorney received 322
    telephone calls and walk-in inquiries. In response, the
    office has moved to vacate and enter a nolle prosequi in
    175 of these cases. No motions to withdraw a guilty plea
    or admission to sufficient facts were filed by defendants.
    In sum, in response to approximately 21,000 letters sent by the
    vendor to Dookhan defendants early in September, 2016, as of
    October 24, 2016, only twenty motions for postconviction relief
    were filed by defendants and 175 motions were filed by
    prosecutors.   In other words, the notice triggered applications
    for postconviction relief in less than one per cent of these
    cases.17
    17
    The Bridgeman petitioners have filed a motion to expand
    the record to add an affidavit from Nancy J. Caplan, the CPCS
    attorney in charge of its Hinton lab crisis litigation unit
    (unit), which was created in April, 2013, to address indigent
    defense matters relevant to the representation of Dookhan
    defendants. Caplan attests that, after the district attorneys
    sent the notice, CPCS asked the courts in the eight affected
    counties and all bar advocates to direct all inquiries arising
    from the notice to the unit so that CPCS could "provide counsel
    to indigent Dookhan defendants so long as it had the resources
    necessary to do so." She declares that, as of October 31, 2016,
    the unit had received inquiries arising from the notice from 139
    Dookhan defendants, who were defendants in 162 cases in which
    Dookhan was the primary or confirmatory chemist.
    26
    Discussion.   The Bridgeman petitioners argue once again for
    the global remedy that we declined in Bridgeman I, 
    471 Mass. 487
    , to implement "at this time."   They ask that we vacate the
    drug convictions of all Dookhan defendants and dismiss them with
    prejudice or, in the alternative, vacate them without prejudice
    and allow prosecutors one year to reprosecute the cases,
    dismissing with prejudice all that are not reprosecuted within
    one year for violation of the speedy trial rule, Mass. R. Crim.
    P. 36 (b) (1) (D), as amended, 
    422 Mass. 1503
     (1996).    They
    contend that due process requires such a global remedy because,
    even though four years have now passed since the scope of
    Dookhan's misconduct was revealed, the defendants' entitlement
    to a new trial on their drug convictions has yet to be
    adjudicated in more than 24,000 cases.   They also contend that
    the notice sent by prosecutors to these defendants was "not a
    serious effort to ensure that wrongful convictions will be
    The motion also seeks to expand the record to include a
    "statement" made by "the District Attorneys for all of the
    Commonwealth's Districts" in ten separate criminal cases in
    Hampden County involving misconduct by another chemist, Sonja
    Farak, at the Department of Public Health's State Laboratory
    Institute in Amherst. In that "statement," the district
    attorneys inform the court that the Commonwealth will not
    contest a finding of "egregious governmental misconduct" by
    Farak in performing her duties at that laboratory under the two-
    prong analysis set forth in Commonwealth v. Scott, 
    467 Mass. 336
    (2014). We allow the motion to expand the record, but recognize
    that the full scope of Farak's misconduct has yet to be
    determined.
    27
    addressed through case-by-case litigation," and was "so
    misleading and incomplete" that its harm can be undone only by
    relieving the defendants of the burdens of case-by-case
    litigation.   They claim that a global remedy is a necessary
    exercise of our superintendence authority because a case-by-case
    adjudication of so many cases is "doomed to fail" given the
    limited resources of the Commonwealth's indigent criminal
    defense system.
    The district attorneys respond that "[t]here is no
    convincing reason to retreat from the thoughtful remedies-based,
    workable solution designed by the [c]ourt."   They contend that
    the notice mailed to the Dookhan defendants was fair, and that
    the low response to the notice reflects that many defendants
    "may conclude that they face no adverse impact at all from a
    closed chapter in their lives," and "feel no urgency" to reopen
    their case "before an adverse impact actually occurs."    They
    contend that, in light of the Dookhan defendants' response to
    that notice, it is apparent that the Bridgeman petitioners have
    greatly overstated the burden that will arise from case-by-case
    adjudication of motions for a new trial.   They also argue that
    we should not vacate the convictions of Dookhan defendants who
    have not moved to do so, because "mass vacatur would constitute
    a complete abandonment of the careful weighing of the interests
    of defendants, the public, and the criminal justice system that
    28
    this [c]ourt set out in Scott, and affirmed in [Bridgeman I] and
    the cases that followed."   They contend that the remedy of
    dismissal with prejudice is not justified as a matter of law,
    and that the remedy of dismissal without prejudice, allowing the
    reprosecution of these cases, would be unfair to impose on
    defendants who did not move for such relief, because it would
    subject them without their approval to a new trial and the risk
    of arrest if they failed to appear.   In short, the district
    attorneys argue that we should stay the course, because
    individual case-by-case adjudication of motions for a new trial
    brought by Dookhan defendants is both practical and fair.
    1.    Four relevant principles of our criminal justice
    system.   In Bridgeman I, 471 Mass. at 487, we recognized that
    "we cannot expect defendants to bear the burden of a systemic
    lapse," but we declined to implement a global remedy "at this
    time" because we would not "allow the misconduct of one person
    to dictate an abrupt retreat from the fundamentals of our
    criminal justice system" (citation omitted).   In revisiting here
    whether the time is now ripe to implement a global remedy, it is
    important to explain four relevant principles of our criminal
    justice system that have guided our prior decisions relating to
    this matter.   First, where there is egregious misconduct
    attributable to the government in the investigation or
    prosecution of a criminal case, the government bears the burden
    29
    of taking reasonable steps to remedy that misconduct.    See
    Strickler v. Greene, 
    527 U.S. 263
    , 281 (1999) (discussing
    "special role played by the American prosecutor in the search
    for truth in criminal trials" and broad duty to disclose
    exculpatory information); Bridgeman I, supra at 480-481.       Those
    reasonable steps include the obligation to timely and
    effectively notify the defendant of egregious misconduct
    affecting the defendant's criminal case.   See Ferrara, 
    456 F.3d at 293
     (government's failure to disclose exculpatory evidence to
    defendant "was so outrageous that it constituted impermissible
    prosecutorial misconduct sufficient to ground the petitioner's
    claim that his guilty plea was involuntary"); Mass. R. Prof. C.
    3.8 (d), as appearing in 
    473 Mass. 1301
     (2016) ("The prosecutor
    in a criminal case shall . . . make timely disclosure to the
    defense of all evidence or information known to the prosecutor
    that tends to negate the guilt of the accused or mitigates the
    offense . . .").
    As applied here, prosecutors had a responsibility timely
    and effectively to disclose Dookhan's misconduct to all affected
    defendants because Dookhan might erroneously have found
    substances that were not controlled substances to be a
    controlled substance, or to be a certain weight, creating the
    risk that a defendant may have been found guilty of a drug crime
    he or she did not commit.   In addition, her egregious misconduct
    30
    put in question the accuracy of the drug analysis and the
    ability of the government to prove the nature and weight of the
    alleged drugs beyond a reasonable doubt, which a defendant is
    entitled to consider in making an informed and voluntary
    decision whether to waive the right to trial and plead guilty
    (or admit to sufficient facts to warrant a finding of guilt), or
    to proceed to trial.   The cost of notifying defendants of
    egregious government misconduct must be borne by the prosecuting
    district attorney's office, even if, as here, the fault belongs
    to the Hinton lab and Dookhan, not the prosecutors.
    Second, under our criminal rules, relief from a conviction
    generally requires the defendant to file a motion for a new
    trial.   See Mass. R. Crim. P. 30 (b), as appearing in 
    435 Mass. 1501
     (2001) (judge "upon motion in writing may grant a new trial
    at any time if it appears that justice may not have been done"
    [emphasis added]).   See also Scott, 467 Mass. at 354.    "A new
    trial motion under Rule 30(b) is the appropriate vehicle to
    attack the validity of a guilty plea or an admission to
    sufficient facts."   Reporters' Notes to Rule 30 (b), Mass. Ann.
    Laws Court Rules, Rules of Criminal Procedure, at 1774
    (LexisNexis 2016).
    Third, dismissal with prejudice "is a remedy of last
    resort."   Commonwealth v. Cronk, 
    396 Mass. 194
    , 198 (1985).
    Where a motion for a new trial is allowed, the conviction is
    31
    vacated, and the prosecutor may retry the defendant on the same
    charge, unless the judge, apart from the vacatur, also dismisses
    the complaint or indictment with prejudice.       We have identified
    "[t]wo parallel legal principles" governing when this last
    resort might be necessary, balancing the rights of defendants
    "against the necessity for preserving society's interest in the
    administration of justice."     
    Id. at 198-199
    .   Under one legal
    principle, where a prosecutor fails to disclose evidence the
    defendant is entitled to receive and the defendant is prejudiced
    by the failure to disclose, a motion to dismiss with prejudice
    should be allowed only where there is "a showing of irremediable
    harm to the defendant's opportunity to obtain a fair trial."
    
    Id. at 198
    .   Dismissal with prejudice is "too drastic a remedy"
    if the error can be remedied and the defendant can still obtain
    a fair trial.   
    Id. at 200
    , and cases cited.
    "Under the alternative principle, prosecutorial misconduct
    that is egregious, deliberate, and intentional, or that results
    in a violation of constitutional rights may give rise to
    presumptive prejudice.   In such instances prophylactic
    considerations may assume paramount importance and the 'drastic
    remedy' of dismissal of charges may become an appropriate
    remedy."   
    Id. at 198-199
    .    This alternative principle is
    narrowly applied; "the only reason to dismiss criminal charges
    because of nonprejudicial but egregious police misconduct would
    32
    be to create a climate adverse to repetition of that misconduct
    that would not otherwise exist."   Commonwealth v. Lewin, 
    405 Mass. 566
    , 587 (1989).
    We dismissed drug charges with prejudice based on both
    alternative grounds where two special agents of the United
    States Drug Enforcement Administration spoke after arraignment
    with the defendant without the approval of defense counsel,
    disparaged defense counsel and the manner in which he was
    conducting the defense, and encouraged the defendant to
    cooperate with Federal authorities.   Commonwealth v. Manning,
    
    373 Mass. 438
    , 440 (1977).   We concluded that this was "a
    deliberate and intentional attack by government agents on the
    relationship between Manning and his counsel in a calculated
    attempt to coerce the defendant into abandoning his defense,"
    
    id. at 443
    , and that "the officers' misconduct was so pervasive
    as to preclude any confident assumption that proceedings at a
    new trial would be free of the taint," 
    id. at 444
    .   We also
    concluded that a "stronger deterrent" than a new trial was
    warranted for this type of misconduct.   
    Id.
    In Scott and Francis, the remedy that we found appropriate
    in cases where a defendant shows prejudice arising from
    Dookhan's misconduct was the allowance of a motion for a new
    trial and the vacatur of the conviction.   We did not order the
    dismissal of the defendant's drug charges with prejudice, or
    33
    suggest that was an appropriate remedy for Dookhan's misconduct
    under either of the alternative legal principles.     Although the
    record does not provide us with data as to the number of
    relevant Dookhan defendants who were reprosecuted after their
    motions for a new trial were allowed, we are aware that some
    defendants were retried and that other defendants later pleaded
    guilty or admitted to sufficient facts to support a guilty
    finding.
    Fourth, where large numbers of persons have been wronged,
    the wrong must be remedied in a manner that is not only fair as
    a matter of justice, but also timely and practical.     Cf. Green
    v. County School Bd. of New Kent County, 
    391 U.S. 430
    , 439
    (1968) (in redressing school desegregation, school board must
    "come forward with a plan that promises realistically to work,
    and promises to realistically work now").   A remedy that is
    perfect in theory is not perfect in fact if it would take too
    long to be accomplished, or if the resources required to
    implement it would overwhelm the limited resources available to
    the courts.   See Hilao v. Estate of Marcos, 
    103 F.3d 767
    , 786
    (9th Cir. 1996) (affirming special master's award of
    compensatory damages based on statistical methods to determine
    amount owed to class of nearly 10,000 victims and survivors of
    decedents who were tortured, executed, or "disappeared" by
    Philippine military or paramilitary groups during fourteen-year
    34
    rule of Ferdinand E. Marcos where "the time and judicial
    resources required to try the nearly 10,000 claims in this case
    would alone make resolution of Hilao's claims impossible").
    Even when the number of persons injured is large and the problem
    is complex, courts endeavor to craft a workable remedy; we do
    not throw up our hands and deny relief because it would be too
    difficult to accomplish.   Cf. Brown v. Plata, 
    563 U.S. 493
    , 511
    (2011) (in addressing prison overcrowding, "[c]ourts may not
    allow constitutional violations to continue simply because a
    remedy would involve intrusion into the realm of [executive]
    administration"); Swann v. Charlotte-Mecklenburg Bd. of Educ.,
    
    402 U.S. 1
    , 28 (1971) (when altering school attendance zones to
    prevent racial segregation, "all awkwardness and inconvenience
    cannot be avoided in the interim period when remedial
    adjustments are being made").   Over the course of its history,
    our judiciary has devised ways to provide redress to widespread
    wrongs through such vehicles as class actions, derivative
    actions, the consolidation of multiple related cases, and the
    appointment of special masters and receivers.   See, e.g., Mass.
    R. Civ. P. 23, as amended, 
    471 Mass. 1491
     (2015) (class
    actions); Mass. R. Civ. P. 23.1, 
    365 Mass. 768
     (1974)
    (derivative actions by shareholders); Mass. R. Civ. P. 42, as
    amended, 
    423 Mass. 1406
     (1996) (case consolidation); Mass. R.
    Civ. P. 53, as amended, 
    423 Mass. 1408
     (1996) (appointment of
    35
    special master).   In short, we as a judiciary must and do find
    ways to make justice not only fair but workable.    See Demoulas
    v. Demoulas, 
    428 Mass. 555
    , 580 (1998), citing 1 D. Dobbs,
    Remedies § 2.1(3), at 63 (2d ed. 1993) ("Equitable remedies are
    flexible tools to be applied with the focus on fairness and
    justice").
    2.   Revisiting the need for a global remedy.   We now
    consider, in light of all that has happened and all that we have
    learned since Bridgeman I, whether we should revisit our
    decision to decline to adopt a global remedy "at this time" to
    resolve the cases of the relevant Dookhan defendants.
    Bridgeman I, 471 Mass. at 487.
    a.   The district attorneys' proposal to stay the course.
    The district attorneys contend that our previous decisions have
    provided an adequate remedy to the relevant Dookhan defendants.
    This argument relies on the key premise that the notice mailed
    to the Dookhan defendants adequately informed them that
    Dookhan's misconduct affected their criminal case and that, as a
    result, they may seek to vacate their drug conviction.
    We reject this premise; we agree with the Bridgeman
    petitioners that the notice sent by the district attorneys was
    wholly inadequate to provide the relevant Dookhan defendants
    with the information necessary to knowingly and voluntarily
    decide whether they should explore with counsel the possibility
    36
    of withdrawing their plea or moving for a new trial.   The
    shortcomings begin with the envelope itself, which identified
    the source of the letter as "RG/2 Claims Administration LLC," a
    source that would appear inconsistent with the words on the
    envelope, "IMPORTANT LEGAL NOTICE FROM THE COMMONWEALTH OF
    MASSACHUSETTS."   Such an envelope invites the risk that the
    notice might be unopened and discarded as "junk mail."
    Among the shortcomings of the letter itself are that it
    failed adequately to inform the Dookhan defendants that the
    Supreme Judicial Court has determined that they are entitled to
    a conclusive presumption that the drug analysis in their case
    was tainted by egregious government misconduct.   Nor did it
    adequately inform them that, as a result, this court has
    determined that they are entitled to withdraw their guilty plea18
    on drug charges if they can show a reasonable probability that
    they would not have pleaded guilty, and instead would have
    decided to go to trial, had they known of Dookhan's misconduct.
    18
    We recognize that recipients of the letter include both
    individuals who pleaded guilty to Dookhan-related charges and
    those who admitted to sufficient facts to warrant a guilty
    finding. Because such an admission is the "functional
    equivalent of a guilty plea" under G. L. c. 278, § 29D, and
    because it exposes a defendant to some of the same collateral
    consequences as a guilty plea, see Commonwealth v. Villalobos,
    
    437 Mass. 797
    , 800 (2002), we treat the admission the same as a
    guilty plea for the purposes of a motion for new trial. Luk v.
    Commonwealth, 
    421 Mass. 415
    , 418 n.6 (1995). In the remaining
    discussion we refer to a guilty plea and an admission to
    sufficient facts to warrant a finding of guilty, collectively,
    as a "guilty plea." See Scott, 467 Mass. at 337 n.1.
    37
    Nor did it adequately inform them that, if they had been
    convicted of a drug charge at trial, they are entitled to a new
    trial if the admission in evidence of their drug analysis might
    have significantly influenced the jury in reaching their
    verdict.     The letter explained that, if their challenge to their
    drug conviction were to succeed, their conviction would be
    vacated and their "case will be returned to active status," but
    did not explain what it meant for their case to be on "active
    status."19    The Spanish translation of the letter is so poor that
    the letter might not be understood by persons who speak only
    Spanish.
    The letter also failed to inform the Dookhan defendants
    that they had a right to counsel if they sought to withdraw
    their plea or move for a new trial and that, if they could not
    afford counsel, one would be appointed for them.    Instead, it
    invited them to speak to their original lawyer on the case and,
    if they did not know how to contact that lawyer, invited them to
    obtain that information from the relevant criminal clerk's
    office.20    The letter also invited them to contact the office of
    the district attorney who prosecuted them "[f]or more
    19
    The letter did explain that, if the district attorney
    decided to try them again on the vacated drug charge, they would
    not face punishment greater than what they had earlier received
    if they were convicted.
    20
    The letter also told recipients that they "may also
    choose to speak to a new lawyer."
    38
    information."   It did not provide a telephone number for CPCS or
    for any other entity that conducts criminal defense.
    Apart from the deficiencies in the notice, we know that a
    substantial number of the Dookhan defendants did not receive the
    letter, because 5,767 were returned as undeliverable.   An
    additional 964 notices were sent to secondary addresses for
    these individuals in an attempt to locate them, but we do not
    know how many of these letters were returned as undeliverable.
    No public notice, either through the newspaper, television, or
    social media, was attempted to provide notice to those whose
    current address could not be located.
    We are skeptical of the district attorneys' explanation
    that so few of the Dookhan defendants chose to respond to the
    letter because most were not interested in "reopening a closed
    chapter in their lives before an adverse impact actually occurs"
    and others believed that "they face no adverse impact at all"
    from this conviction.   We recognize that few, if any, of the
    relevant Dookhan defendants continue to be incarcerated on a
    drug conviction tainted by Dookhan's misconduct, but that does
    not mean that they lack a strong reason to seek to have this
    conviction vacated, given the serious and pervasive collateral
    consequences that arise from a drug conviction.   A noncitizen,
    even one lawfully residing in this country, who is convicted of
    any crime "relating to a controlled substance," which includes
    39
    the crime of possession of heroin, cocaine, or more than thirty
    grams of marijuana, is "deportable."    
    8 U.S.C. § 1227
    (2)(B)(i)
    (2012).   See Padilla v. Kentucky, 
    559 U.S. 356
    , 368 (2010);
    Commonwealth v. DeJesus, 
    468 Mass. 174
    , 175 (2014).     All
    persons, including United States citizens, who are convicted of
    drug crimes may be barred from public housing and from Federal-
    and State-subsidized private housing.   See 
    42 U.S.C. § 13661
    (2012); 
    24 C.F.R. §§ 960.204
    (a)(1), 982.553(a)(1), (2)(ii);
    G. L. c. 121B, § 32 (State-funded public housing); 760 Code
    Mass. Regs. § 5.08(1)(d) (1996); 760 Code Mass. Regs.
    § 49.03(2)(f) (2012) (Massachusetts Rental Voucher Program); 803
    Code Mass. Regs. § 5.04 (2012).   A drug conviction may bar a
    defendant from many categories of jobs and professional
    licenses.   See, e.g., G. L. c. 6, §§ 172 (c), 172A-172M.     See
    also Commonwealth v. Pon, 
    469 Mass. 296
    , 317 (2014) (collateral
    consequences include homelessness and unemployment).    It may
    also prevent a defendant from receiving government benefits such
    as cash assistance and unemployment benefits.   See G. L.
    c. 151A, § 25 (e) (unemployment benefits); 106 Code Mass. Regs.
    § 701.110(D) (2016) (cash assistance under transitional aid to
    families with dependent children program).   And it may render a
    student temporarily ineligible for Federal financial aid,
    thereby diminishing a defendant's ability to attend college.        
    20 U.S.C. § 1091
    (r)(1) (2012).   A conviction of drug trafficking
    40
    results in the automatic suspension of the defendant's driver's
    license, which makes it more difficult to find and keep
    employment.     G. L. c. 90, § 22½, inserted by St. 2016, c. 64,
    § 1.    A prior drug conviction may also result in a lengthy
    minimum mandatory sentence for those subsequently convicted of
    additional drug offenses, G. L. c. 94C, §§ 32 (b), 32A (b),
    32B (b), 32C (b), 32D (b), 34, or of the illegal possession of a
    firearm.     G. L. c. 269, § 10G.   In short, the adverse
    consequences of an unjust conviction do not end when one
    completes a jail or prison term, or a probationary period.
    Given the inadequacy of the notice provided by the district
    attorneys, the remarkably low response to that notice, and the
    severe collateral consequences of drug convictions, justice and
    fairness do not permit us simply to stay the course set in
    Bridgeman I.
    b.   The Bridgeman petitioners' proposal for a global
    remedy.     The Bridgeman petitioners contend that, even with
    adequate notice, no remedy premised on case-by-case adjudication
    can work.    They argue that, because of the severely limited
    resources of CPCS -- the amount of State funding, the number of
    qualified bar advocates, and the legislative limits on the
    number of hours that bar advocates annually may bill to CPCS --
    CPCS cannot possibly assign qualified counsel to represent all
    the defendants who would file the postconviction motions that
    41
    would result from truly adequate notice.   They therefore contend
    that it is both illusory and misleading to inform defendants
    that, if they are indigent, counsel will be assigned to
    represent them, where that will simply not be possible.     They
    contend that the only just and practical alternative under these
    circumstances is the global remedy they propose, in which we
    would vacate the drug convictions of all relevant Dookhan
    defendants and dismiss them with prejudice, or dismiss them
    without prejudice and allow prosecutors one year to reprosecute
    these cases before they, too, would be dismissed with prejudice.
    The proposed global remedy, however, is neither as just nor
    as practical as the Bridgeman petitioners claim, and it would be
    inconsistent with some of the principles that we earlier
    articulated.   In Scott and Francis, we granted relevant Dookhan
    defendants a conclusive presumption of egregious government
    misconduct, but we did not grant them a conclusive presumption
    of prejudice; defendants still bore the burden of proving
    prejudice.   Where a relevant Dookhan defendant filed a motion to
    withdraw a plea or for a new trial, and failed to prove
    prejudice, the motion was denied.   The global remedy proposed by
    the Bridgeman petitioners would effectively declare a conclusive
    presumption of prejudice.
    Even where a relevant Dookhan defendant proved prejudice,
    the defendant only obtained a new trial under Scott and Francis,
    42
    not a dismissal with prejudice.   Dookhan's conduct, serious as
    it was, did not result in "irremediable harm to the defendant's
    opportunity to obtain a fair trial."    Cronk, 
    396 Mass. at 198
    .
    Rather, it meant that the Commonwealth had to retest the
    substance claimed to be a controlled substance and offer
    evidence of that new drug analysis at a retrial, or otherwise
    prove that the substance possessed or distributed by the
    defendant was a controlled substance.   Nor, given the absence of
    any evidence of misconduct by a prosecutor or investigator, did
    we place Dookhan's misconduct in the category that requires a
    stronger deterrent than a new trial to avoid the risk of
    repetition.   See Lewin, 
    405 Mass. at 587
    ; Manning, 
    373 Mass. at 444
    .   A dismissal with prejudice for government misconduct is
    very strong medicine, and it should be prescribed only when the
    government misconduct is so intentional and so egregious that a
    new trial is not an adequate remedy.    We did not prescribe this
    medicine in Scott and Francis, and we are not convinced that it
    is appropriate to do so now.   And if we were to prescribe it
    now, we would equitably have to address the claims of those who
    earlier prevailed in proving prejudice and therefore won a new
    trial, but not a dismissal with prejudice, and subsequently
    either again pleaded guilty to the same or lesser charges or
    were convicted at a new trial of the drug charges.    They could
    43
    justly contend that they are as entitled to a dismissal with
    prejudice as are those who did not move for a new trial.
    To vacate the convictions of all relevant Dookhan
    defendants without prejudice would present other problems of
    justice and practicality.   We require a defendant to move for a
    new trial for a reason -- without a motion, we cannot be sure
    that a defendant wishes to accept the risk that the Commonwealth
    will retry the defendant rather than issue a nolle prosequi.
    Even though, as a result of our decision in Bridgeman I, 471
    Mass. at 477, a defendant at a new trial would not be risking
    conviction of a more serious crime or a longer sentence, a
    defendant who is retried would still have to appear in court
    when directed by the judge and endure the uncertainty and
    disruption inherent in being a defendant in a criminal trial.
    We might be skeptical of the district attorneys' contention that
    most of the relevant Dookhan defendants do not wish to reopen "a
    closed chapter in their lives," but it would not be surprising
    if some defendants have no wish to relitigate their earlier
    criminal cases and instead simply want to move on with their
    lives.
    Although we reject the global remedy proposed by the
    Bridgeman petitioners, we accept two premises of their argument.
    First, in light of the unusual circumstances of the relevant
    Dookhan defendants, all who are indigent and wish to explore
    44
    whether to move for a new trial under Mass. R. Crim. P. 30 (b)
    are entitled to appointed counsel.   We recognize that we have
    declared that "an indigent defendant does not have an absolute
    right under any provision of the United States Constitution or
    the Massachusetts Declaration of Rights to appointed counsel in
    preparing or presenting his motion for a new trial."
    Commonwealth v. Conceicao, 
    388 Mass. 255
    , 261 (1983).    But we
    have also declared that the State must "ensure that indigent
    defendants have meaningful access to this postconviction
    proceeding," 
    id.,
     and that, "when a defendant presents a motion
    for a new trial which raises a colorable or meritorious issue,
    'it is much the better practice to assign counsel.'"     
    Id. at 262
    , quoting Dillon v. United States, 
    307 F.2d 445
    , 448 (9th
    Cir. 1962).
    Generally, the decision whether to appoint counsel to
    represent a defendant in preparing and presenting a motion for a
    new trial rests with the sound discretion of the motion judge.
    Mass. R. Crim. P. 30 (c) (5), as appearing in 
    435 Mass. 1501
    (2001).   But in the exercise of that discretion a judge should
    appoint counsel where the failure to do so would deprive an
    indigent defendant "of meaningful access" or result in
    "fundamental unfairness."   Conceicao, 
    supra at 262
    , citing Ross
    v. Moffitt, 
    417 U.S. 600
    , 616 (1974), and Lassiter v. Department
    of Social Servs., 
    452 U.S. 18
    , 24-25 (1981).
    45
    Here, all of the relevant Dookhan defendants who move for a
    new trial are entitled under our decision in Scott to a
    conclusive presumption of egregious government misconduct.     The
    district attorneys concede that, given the number of relevant
    Dookhan defendants, we have the authority under our
    superintendence power to order that each relevant Dookhan
    defendant who is indigent is entitled to the assignment of
    counsel.   We so order; we need not wait for each motion judge to
    rule individually on the question of the assignment of counsel
    where it is plain that the absence of counsel under these
    unusual circumstances would deny an indigent defendant
    "meaningful access" or result in "fundamental unfairness," and
    therefore deprive the defendant of his or her constitutional
    rights to due process and to counsel.   The right to appointed
    counsel applies here regardless of whether the relevant Dookhan
    defendant has completed his or her sentence, because the severe
    collateral consequences arising from a drug conviction do not
    end at the conclusion of a defendant's sentence.
    Moreover, where an indigent criminal defendant has a right
    to counsel, "[t]he duty to provide such counsel falls squarely
    on government, and the burden of a systemic lapse is not to be
    borne by defendants."   Lavallee v. Justices in the Hampden
    Superior Court, 
    442 Mass. 228
    , 246 (2004).   Where a judge finds
    that a criminal defendant has a right to counsel and is indigent
    46
    (or indigent but able to contribute), the judge assigns CPCS to
    provide representation for the party.    S.J.C. Rule 3:10, § 6, as
    appearing in 
    475 Mass. 1301
     (2016).     G. L. c. 211D, § 5 (CPCS
    "shall establish, supervise and maintain a system for the
    appointment or assignment of counsel" at any stage of criminal
    proceeding where there is right to counsel and defendant is
    indigent).   If CPCS, despite its best efforts, were unable to
    assign counsel to a defendant in a reasonably timely manner --
    whether the reason be the absence of necessary funding by the
    Legislature, the inability of CPCS to qualify adequate numbers
    of private attorneys to serve as bar advocates because of the
    low hourly fee mandated by the Legislature,21 the unavailability
    of qualified bar advocates because of the limitation on the
    21
    The present statutory hourly rate for bar advocates is
    fifty-three dollars for cases in the District Court and the
    Boston Municipal Court, and sixty dollars for nonhomicide cases
    in the Superior Court. G. L. c. 211D, § 11 (a). The only
    change to these hourly rates since 2005 has been that the rate
    applicable for cases in the District Court and Boston Municipal
    Court was increased from fifty dollars to fifty-three dollars in
    2015. See St. 2015, c. 46, § 119.
    47
    number of hours they may bill annually,22 or a systemic overload
    created by an overwhelming number of relevant Dookhan defendants
    filing motions for a new trial (or the combination of all four
    reasons) -- we would have to fashion an appropriate remedy under
    our general superintendence authority for the constitutional
    violation suffered by indigent criminal defendants.    See
    Lavallee, supra at 244.   In Lavallee, where the list of CPCS-
    qualified attorneys available to accept assignments in Hampden
    County was inadequate to ensure the provision of counsel to
    those with a right to counsel, the remedy we ordered was that a
    criminal case against an indigent defendant must be dismissed
    without prejudice if an attorney had not filed an appearance
    within forty-five days of arraignment.   Id. at 246.
    We recognize that, if a substantial percentage of relevant
    Dookhan defendants were to seek postconviction relief after
    22
    The annual cap on billable hours for bar advocates is
    1,650 hours, and a bar advocate may not accept any new
    appointment in a nonhomicide case after having billed 1,350
    hours in that fiscal year. G. L. c. 211D, § 11 (b), (c). In
    2016, in response to a shortage of bar advocates in care and
    protection cases and children and family law cases, the
    Legislature enacted legislation allowing the chief counsel of
    CPCS, under certain circumstances, to waive the annual cap on
    billable hours for bar advocates assigned to these cases,
    provided that such a bar advocate not bill in excess of 1,800
    billable hours for the year. G. L. c. 211D, § 11(d), amended
    through St. 2016, c. 133, § 119. A comparable increase in the
    annual cap on billable hours potentially could be enacted for
    bar advocates assigned to criminal cases or, alternatively, the
    time devoted to the representation of relevant Dookhan
    defendants could be exempted from the annual cap.
    48
    receiving truly adequate notice, the capacity of CPCS to assign
    qualified attorneys to represent these defendants in case-by-
    case adjudication would soon be overwhelmed.   Therefore, unless
    the district attorneys were to move to vacate and dismiss with
    prejudice the drug convictions of large numbers of relevant
    Dookhan defendants, case-by-case adjudication poses the
    considerable risk that the demand of indigent Dookhan defendants
    for counsel might outstrip the supply of CPCS-qualified
    attorneys to represent them, and require this court to implement
    an appropriate remedy under our general superintendence
    authority for the constitutional violation suffered by indigent
    criminal defendants who are denied their right to counsel.       If
    past is prologue, that remedy will likely be the dismissal
    without prejudice of their challenged drug convictions.       See
    Lavallee, 442 Mass. at 246.
    c.   New protocol for case-by-case adjudication.    The
    extraordinary magnitude of Dookhan's misconduct has left us with
    only poor alternatives.    We continue to believe that, despite
    its considerable risks and burdens, case-by-case adjudication is
    the fairest and best alternative to resolve the drug cases
    potentially tainted by Dookhan's misconduct and the alternative
    most consistent and in harmony with the relevant principles of
    criminal justice that have and continue to guide us in this
    extraordinary situation.    But we recognize that, in light of the
    49
    potential need to adjudicate more than 20,000 motions for a new
    trial brought by the relevant Dookhan defendants, case-by-case
    adjudication must be adapted to make it both fair and workable.
    The success of case-by-case adjudication will depend on the
    cooperation of the district attorneys, who will have to examine
    each drug conviction of each relevant Dookhan defendant in their
    district and determine which cases they reasonably could and
    would reprosecute if a motion for a new trial were granted, and
    move to vacate and dismiss with prejudice the rest.23   We rely on
    the exercise of the district attorneys' sound discretion to
    reduce substantially the number of relevant Dookhan defendants.
    We note that it appears that the majority of the drug
    convictions of relevant Dookhan defendants were of possession
    23
    In a letter to the Governor on September 6, 2012, after
    learning of the investigation of the Hinton lab, the district
    attorneys declared, "If there has been any miscarriage of
    justice due to the actions of Annie Dookhan or anyone else at
    the [Hinton lab], correcting those miscarriages must be the
    first priority." Press Release, MDAA Letter to Gov. Patrick Re:
    DPH Drug Lab, State House News Serv. (Sept. 11, 2012). At oral
    argument, the district attorneys similarly assured the court
    that they will exercise their sound discretion in handling
    motions for a new trial brought by the relevant Dookhan
    defendants.
    50
    alone,24 that approximately ninety per cent of these convictions
    were obtained in the District Court or in the Boston Municipal
    Court (which means that the drug charges were either
    misdemeanors or felonies for which the district attorney did not
    choose to seek indictments), and that virtually all of these
    defendants have already served the entirety of their sentences
    for these drug convictions.
    Its success also depends on the cooperation of CPCS, which
    will have to make best efforts in using the funding appropriated
    by the Legislature to assign counsel to the relevant Dookhan
    defendants who, after new notice, choose to explore the filing
    of a motion for a new trial.   We look to CPCS also for its
    creativity and ingenuity in finding ways to assign attorneys to
    represent as many relevant Dookhan defendants as is reasonably
    possible.
    To accomplish case-by-case adjudication of the drug cases
    of potentially more than 20,000 relevant Dookhan defendants, we
    establish the following protocol, to be completed in three
    24
    An analysis conducted by Paola Villarreal, a data science
    fellow at the American Civil Liberties Union Foundation of
    Massachusetts, revealed that approximately sixty-two per cent of
    the adverse drug dispositions for Dookhan defendants were for
    possession alone. At oral argument, in answer to a question
    posed by a Justice, a prosecutor stated that he "[did] not know"
    whether a majority of these cases were for "straight
    possession."
    51
    phases, and order its implementation by the single justice in
    the form of a declaratory judgment.
    i.   Phase one.   Upon the issuance of this opinion, each
    district attorney shall commence an individualized review of
    every Dookhan case in his or her district that was included on
    the list that the district attorney earlier submitted to the
    single justice.   No later than ninety days after the issuance of
    this opinion, each district attorney shall file three letters
    with the county clerk.25
    The first letter shall identify all defendants on the list
    who are not relevant Dookhan defendants because they pleaded
    guilty to a drug charge before Dookhan signed the drug
    certification and therefore are not entitled to the conclusive
    presumption of egregious government misconduct.     In short, this
    letter shall identify all of the so-called Ruffin defendants.
    See Ruffin, 475 Mass. at 1003.
    The second letter shall identify all of the drug
    convictions on the list that the district attorney moves to
    vacate and dismiss with prejudice as a result of his or her
    individualized review.     These shall include both the convictions
    that the district attorney wishes to vacate and dismiss with
    prejudice, regardless of whether the case could be successfully
    25
    We recognize the difference between the date of the
    issuance of our opinion and the date of the rescript, and have
    specifically selected the former as the starting date.
    52
    reprosecuted if a new trial were ordered, and the convictions
    that the district attorney could not successfully reprosecute if
    a new trial were ordered.    Once these drug convictions are
    vacated and dismissed with prejudice, the defendants shall be
    notified of the action taken.26
    The third letter shall identify all drug convictions on the
    list that the district attorney does not move to vacate and
    dismiss with prejudice.     For each such conviction, the district
    attorney shall certify that, if a motion for a new trial were
    allowed, the district attorney could produce evidence at a
    retrial, independent of Dookhan's signed drug certificate or
    testimony, sufficient to permit a rational jury to find beyond a
    reasonable doubt that the substance at issue was the controlled
    substance alleged in the complaint or indictment.     Such
    independent evidence may include, for example, retesting of the
    original drug evidence, a positive field test, or a specific
    admission by the defendant regarding his or her knowledge of the
    nature of the substance that was made before Dookhan signed the
    drug certificate in the case.     Only the relevant Dookhan
    defendants identified in the third letter shall be provided with
    new notice in phase two, discussed infra.
    26
    Where a defendant pleaded guilty to multiple charges at a
    plea hearing or was convicted at trial of multiple counts, the
    vacatur of these drug convictions with prejudice will not affect
    any nondrug convictions or any drug convictions where Dookhan
    was not the primary or confirmatory analyst.
    53
    In light of the massive number of relevant Dookhan
    defendants and the scope of misconduct attributable to the
    government (albeit not to the prosecutors), it is only fair that
    district attorneys make an individualized determination whether
    a conviction warrants burdening the court system with the
    adjudication of a motion for a new trial, CPCS with the
    assignment of counsel for those who are indigent, and the
    taxpayers with payment for the notice and for assigned counsel,
    especially where a defendant has already served the entirety of
    the sentence.   A substantial vetting of the relevant cases by
    the district attorneys will allow our criminal justice system to
    focus its limited resources where they are most needed, and
    diminish the risk that the number of these cases will so
    overwhelm CPCS that the single justice will have to act to
    protect the relevant Dookhan defendants' right to counsel.27
    27
    Our focus in the phase one protocol on whether the
    Commonwealth could obtain a drug conviction against the relevant
    Dookhan defendants with evidence untainted by Dookhan's
    misconduct is comparable to the approach taken by New Jersey
    courts following revelations of misconduct by a police officer
    who made numerous drunk driving arrests. In State v. Gookins,
    
    135 N.J. 42
    , 44-45 (1994), three defendants moved to vacate
    their guilty pleas for driving while under the influence of
    alcohol after the police officer involved in their arrests and
    the administration of their breathalyzer tests was convicted of
    falsifying the result of the breathalyzer test he had performed
    on an undercover agent, and of stealing money from drivers whom
    he had stopped. The defendants had pleaded guilty in reliance
    on the results of their breathalyzer tests. 
    Id. at 45
    . The New
    Jersey Supreme Court vacated their convictions and issued an
    order requiring the prosecution to certify to the trial court
    54
    ii.   Phase two.   In the second phase of the protocol, no
    later than thirty days after the expiration of the ninety-day
    period in phase one, new notice shall be provided to all
    relevant Dookhan defendants identified in the district
    attorneys' third letters.    The notice shall consist of a mailing
    that is approved by the single justice as to its content, its
    envelope, and its mode of delivery.28   The single justice shall
    also have the authority to order additional forms of public
    notice, such as through newspapers or social media, to enhance
    the effectiveness of the mailing and to attempt to reach those
    who might not receive it.
    "all the evidence that it considers to be untainted that would
    sustain the prosecution of these cases, . . . excluding the
    testimony of [the convicted officer]." 
    Id. at 51
    . The trial
    court was instructed to hold a hearing "to determine whether
    such evidence is sufficient to permit the State to proceed with
    the case." 
    Id. at 52
    . In a separate class action in the United
    States District Court, the State consented to the appointment of
    a special master to review all drunk driving cases of class
    members involving the convicted officer and determine whether
    those convictions should be reversed. 
    Id. at 51
    . The special
    master conducted an individualized review of these cases and
    determined that "the only evidence inculpating the [defendants]
    came from a police officer known to be corrupt." See Dickerson
    vs. Kane, U.S. Dist. Ct., No. 92-2528 (D.N.J. July 17, 1995).
    The District Court judge adopted the findings of the special
    master and ordered the reversal of 151 drunk driving
    convictions. 
    Id.
    28
    We leave to the single justice the question whether
    certified mail or some other comparable means of delivery is
    appropriate to determine whether the defendant actually receives
    the notice.
    55
    The new notice shall not only address the deficiencies
    described in the content of the first written notice sent by the
    district attorneys, but also simplify the process for defendants
    to move for a new trial.   The notice should identify the
    telephone number of a "hotline" staffed by CPCS, so that persons
    who receive the notice can seek immediate guidance.   The mailing
    should permit a relevant Dookhan defendant to declare, simply by
    checking a box, that the defendant wishes to discuss with
    counsel whether the defendant should attempt to vacate his or
    her drug conviction by filing a motion for a new trial, and
    should also include a form indigency affidavit for the defendant
    to fill out if he or she claims to be indigent and therefore
    qualifies for the assignment of counsel.   CPCS is encouraged to
    draft and include within the mailing a separate letter providing
    the legal guidance and information that CPCS would generally
    provide to a relevant Dookhan defendant who would telephone its
    hotline.   Because this guidance letter, unlike the notice,
    constitutes legal advocacy and not simply legal information, and
    might encourage relevant Dookhan defendants to move for a new
    trial to eliminate the collateral consequences arising from
    their drug conviction, the content of this letter shall not
    require the approval of the single justice.   Along with the
    notice, the guidance letter, the check-off sheet, and the form
    indigency affidavit, the mailing shall include a stamped, self-
    56
    addressed envelope so that, once completed, the documents may be
    returned to an address designated by the single justice.    Where
    a relevant Dookhan defendant returns the documents indicating
    that he or she is indigent and wishes to explore with counsel
    the filing of a motion for a new trial, the single justice shall
    make an indigency determination and, where indigency is found,
    shall order CPCS to assign counsel to the defendant.   No action
    shall be taken regarding any relevant Dookhan defendant's
    conviction where he or she does not return the documents or
    otherwise move for a new trial.
    The single justice shall also address the challenge created
    by the substantial number of relevant Dookhan defendants who
    have yet to be successfully located.   As it stands now, these
    defendants have yet to be informed that the substance at issue
    in their case was tested by Dookhan in the Hinton lab, that
    Dookhan's misconduct over many years has been found to be
    egregious government misconduct, and that they are entitled to
    the conclusive presumption of egregious government misconduct if
    they were to move for a new trial.   Because they have not yet
    been so informed, they effectively have been denied the
    opportunity to seek redress for this misconduct.
    The district attorneys have an obligation to take all
    reasonable steps necessary to provide these individuals with
    notice of Dookhan's misconduct, and that includes reasonable
    57
    efforts to locate them, wherever they might be residing.     Where,
    despite reasonable efforts, the district attorneys are unable to
    obtain an address for a relevant Dookhan defendant, or where the
    notice is returned as undeliverable, the single justice shall
    direct the relevant district attorney to locate the current
    address of the defendant's last attorney of record in the case.
    The notice and accompanying documents shall be sent to that
    attorney, with a cover letter asking the attorney to make best
    efforts to locate his or her former client so that effective
    notice can be accomplished.   In addition, the single justice
    shall have the authority to direct the probation department to
    include a notation in the missing defendant's board of probation
    record indicating that the defendant is a relevant Dookhan
    defendant, so that the defendant can receive the required notice
    and related documents if he or she returns to court.   For the
    relevant Dookhan defendants who cannot otherwise be located, the
    single justice shall also have the authority to order the use of
    social or other media to provide the notice and related
    documents, or information regarding them.
    The financial burden of notifying defendants of egregious
    government misconduct that affected their criminal cases must be
    borne by the prosecuting district attorney's office, even if, as
    here, the fault belongs to the Hinton lab and Dookhan, not the
    prosecutors.   Therefore, the cost of providing new and adequate
    58
    notice, including but not limited to the cost of mailing, of
    locating missing defendants, and of publicity through social and
    other media, shall be borne by the district attorneys, with the
    allocation of those costs to be determined by the single
    justice.   We recognize that this cost could be considerable, but
    that is a consequence of egregious government misconduct that
    affected more than 20,000 defendants.   We also note that a
    district attorney may reduce the amount of this cost by reducing
    the number of defendants identified in the third letter.      The
    failure of a district attorney to bear the district's
    proportionate share of these costs shall be deemed equivalent to
    a failure to provide defendants with exculpatory information,
    with the sanctions appropriate to such a failure.
    iii.   Phase three.   In the third phase, CPCS shall identify
    in writing to the single justice all cases, if any, where CPCS
    received an order for the assignment of counsel, but was unable
    within sixty days of the order to assign counsel despite CPCS's
    best efforts.   The single justice shall then make a factual
    finding, after hearing, whether CPCS has made best efforts to
    assign counsel in these cases.   In those cases where the single
    justice makes such a finding, the single justice shall issue an
    order to show cause why the drug conviction of this
    unrepresented defendant should not be vacated, and set a date
    for a show cause hearing where the Commonwealth will have an
    59
    opportunity to be heard.   At or after that hearing, if the
    single justice determines that relevant Dookhan defendants have
    been denied their right to counsel because of the inability of
    CPCS, despite its best efforts, to assign counsel to represent
    the defendants, the single justice may order that the drug
    convictions at issue be vacated and dismissed without prejudice,
    unless the interests of justice otherwise dictate.29   See
    Lavallee, 442 Mass. at 246.
    Conclusion.   The case is remanded to the single justice for
    the entry of a declaratory judgment as provided in this opinion
    and for further action consistent with this opinion.30
    So ordered.
    29
    We recognize our authority to appoint a special master to
    assist the single justice in his or her exercise of our
    superintendence authority in these cases. See S.J.C. Rule 2:13,
    as appearing in 
    382 Mass. 749
     (1981).
    30
    Because we recognize the challenges involved in
    implementing the three-phase protocol, the single justice is
    authorized to make necessary revisions if any part of it is
    determined to be impracticable. In addition, if this protocol
    for any reason were to prove inadequate in practice to remedy
    the wrong despite the best efforts of the parties, the single
    justice may issue a new reservation and report to the full
    court.
    LENK, J. (concurring, with whom Budd, J., joins).     It has
    been over five years since the stunning misconduct of a rogue
    chemist at the State's William A. Hinton State Laboratory
    Institute (Hinton lab) first came to light.   The nature, scope,
    and adverse consequences of that misconduct on the individuals
    directly affected, on our system of justice, and on the
    taxpayers who must foot the bill for this lamentable turn of
    events are all ably recounted in the court's opinion, as well as
    in the dissenting opinion.   I write separately to underscore
    that, in those five years, and despite the time and efforts of so
    many, we have managed to address fewer than 2,000 of the
    estimated 20,000 or more cases involving Annie Dookhan-tainted
    evidence.   We cannot go on this way.
    Even as we speak, the myriad ripple effects of one woman's
    misdeeds continue to afflict the relevant Dookhan defendants,
    thousands and thousands of whom already have served their time
    for convictions that we now know to be suspect.   As a result of
    having a prior drug conviction, many of those same people, some
    of whom may not even know to this day of Dookhan's fateful role
    in their lives, may now find themselves unable to get work or
    housing, obtain or keep needed professional and drivers'
    licenses, attend college, receive government benefits, or even
    stay in this country.   Mindful of this, I share the dissenting
    Justice's frustration with the unacceptably glacial systemic
    2
    response to date and join in her view that extraordinary measures
    are now in order.   For reasons explained in the court's opinion,
    however, I regard the protocol announced today (Bridgeman II
    protocol) as promising to be such a measure, but only if
    implemented in a manner that countenances no further delays.    For
    the protocol to achieve its goals and end this "blight on the
    integrity of our criminal justice system," post at   , there must
    be strict compliance with its stringent timelines and
    requirements.   Only this will forestall the need for a
    "Bridgeman III" and different measures.
    While blame for the difficult situation in which we find
    ourselves lies solely with Dookhan and the Hinton lab that
    allowed it to happen -- and it cannot be said too many times that
    fault most certainly does not lie with the prosecutors who,
    without knowing its tainted provenance, in good faith used the
    evidence Dookhan created -- we consistently have recognized that
    her misdeeds must be attributed to the government, and that the
    government must bear the responsibility to put things right.
    Just as the success of the Bridgeman II protocol will depend on
    its timely and rigorous implementation, so too will its viability
    turn, at least initially, on the willingness of the district
    attorneys promptly to dismiss with prejudice a truly significant
    number of the roughly 20,000 relevant Dookhan defendants'
    cases -- at a minimum, those for simple possession in which
    3
    sentences already have been served.     See ante at note 24.   Not
    doing so in the first phase of the protocol will of necessity add
    to the already staggering human and financial costs of the
    scandal and risk overloading the already strained public defense
    system.   In this regard, we cannot turn a blind eye to the
    potential costs of the looming crisis of thus far undetermined
    magnitude caused in western Massachusetts by Sonja Farak, yet
    another rogue chemist employed by a State laboratory.    And, as to
    the presumably limited number of remaining cases that the
    district attorneys decline to dismiss, truly informative notice
    to the defendants involved, using whatever modes of communication
    will be effective, is vital to achieving the fair and workable
    outcome contemplated by the protocol.
    Recognizing what Dr. Martin Luther King, Jr., once called
    "the fierce urgency of now," we must act swiftly and surely to
    staunch the damage and to make things as right as we can.      The
    Bridgeman II protocol draws upon the deep roots of our
    jurisprudence to craft a response that, consistent with
    fundamental principles, will bring this deplorable episode
    forthwith to a just resolution once and for all.     May it be so.
    HINES, J. (dissenting).   The petitioners and intervener
    (collectively, petitioners) are before this court once again
    seeking a global remedy for the more than 20,000 defendants
    whose convictions were tainted by Annie Dookhan’s unprecedented1
    and far-reaching misconduct at the William A. Hinton State
    Laboratory Institute.    The court rejects a global remedy,
    adopting the view that "despite its considerable risks and
    burdens, case-by-case adjudication is the fairest and best
    alternative to resolve the cases potentially tainted by
    Dookhan's misconduct."    Ante at    .   I disagree.   Now, more
    than five years after Dookhan's misconduct first came to light,
    the need to adopt a swift and sure remedy for the harm caused by
    her deceit presents itself with palpable urgency.      The time has
    come to close the book on this scandal, once and for all, by
    adopting a global remedy.    While I agree, as the court notes,
    that a global remedy is "strong medicine," ante at        , the
    continuing violation of the rights of the defendants affected by
    Dookhan's misconduct and the damage to the integrity of our
    criminal justice system demand no less.
    Contrary to the court's assessment of the case-by-case
    procedure offered as the solution to the problem the court is
    obliged to solve, it is neither the fairest nor the best
    1
    An exhaustive search of reported cases yielded not a
    single case involving misconduct comparable to that committed by
    Dookhan.
    2
    alternative for remedying the manifest injustice to the
    defendants caught up in the Dookhan scandal and for restoring
    the integrity to our criminal justice system.    It fails as the
    "fairest" alternative because it flouts the guiding principle
    that "in the wake of government misconduct that has cast a
    shadow over the entire criminal justice system, it is most
    appropriate that the benefit of the remedy inure to the
    defendants."    Commonwealth v. Scott, 
    467 Mass. 336
    , 352 (2014),
    citing Lavallee v. Justices in the Hampden Superior Court, 
    442 Mass. 228
    , 246 (2004).    It also fails as the "best" alternative
    because it is simply unworkable as a timely and effective
    mechanism for addressing the due process claims of the thousands
    of defendants now deemed to have been convicted on Dookhan's
    tainted evidence.     In short, the court's solution is too little
    and too late.    The only fitting end to this blight on the
    integrity of our criminal justice system is vacatur and
    dismissal with prejudice of the convictions of all relevant
    Dookhan defendants.    Therefore, I dissent.
    The case for a global remedy.      We have been here before.
    We acknowledged in Scott, 467 Mass. at 352, that Dookhan's
    misconduct caused "a lapse of systemic magnitude in the criminal
    justice system."    Recognizing the "particularly insidious"
    nature of Dookhan's misconduct and that it "belies
    reconstruction," we adopted a conclusive presumption of
    3
    egregious government misconduct as an accommodation to those
    defendants able to establish Dookhan's role in producing the
    evidence upon which their conviction was based.         Id.   Later in
    Bridgeman v. District Attorney for the Suffolk Dist., 
    471 Mass. 465
     (2015) (Bridgeman I), we declined the invitation to
    implement a global remedy for the thousands of cases affected by
    Dookhan's misconduct "at this time."      
    Id. at 487
    .    Signaling a
    preference for a measured approach rather than the more drastic
    global remedy advocated by the petitioners, we noted that "our
    decisions in Scott and [Commonwealth v. Charles, 
    466 Mass. 63
    (2013)], have provided Dookhan defendants . . . with meaningful
    solutions for addressing concerns that have arisen as these
    defendants attempt to challenge their drug convictions."          
    Id.
    Since Bridgeman I, however, Scott's promise as a hedge
    against the wholesale violation of the due process rights of
    this class of defendants has been undermined by the sheer
    magnitude of the problem.      Scott was decided without the benefit
    of the investigative reports establishing the scope of Dookhan's
    misconduct.2    The court reasonably assumed, therefore, that the
    jurisprudential shortcut to proving Dookhan's misconduct would
    make a case-by-case approach workable.     Because we now know the
    extent of Dookhan's misconduct and that it has not yet been
    mitigated in any significant respect by the measures in Scott
    2
    See ante at note 6.
    4
    and Charles, that assumption is no longer valid.   With a clearer
    eye on the scope of the problem, Scott's characterization of
    Dookhan's misconduct as a "lapse of systemic magnitude" still
    stands as an apt factual and legal context for the petitioners'
    claims.   Scott, 467 Mass. at 352.
    In this case, as in Scott, we are called upon to "exercise
    our superintendence power [under G. L. c. 211, § 3,] to fashion
    a workable approach to motions to withdraw a guilty plea brought
    by defendants affected by [Dookhan's] misconduct."   Id.    In this
    undertaking, the appropriate analytical framework is that
    articulated in Scott.3   We noted that in fashioning a remedy for
    the "systemic lapse" caused by Dookhan's misconduct, "[w]e must
    account for the due process rights of defendants, the integrity
    of the criminal justice system, the efficient administration of
    justice in responding to such potentially broad-ranging
    misconduct, and the myriad public interests at stake."     Id.   In
    3
    Without clearly explaining why, the court strays from the
    analytical framework we adopted in Scott, relying instead on a
    self-selected set of "principles" explained in elaborate detail.
    Ante at    . I agree that these principles are firmly rooted in
    our jurisprudence, but they are not necessarily dispositive of
    the issue presented here. Absent a reason to play by a
    different set of rules from that articulated in Scott, 467 Mass.
    at 352, and reiterated in Bridgeman I, 471 Mass. at 487, as an
    appropriate standard to apply in "fashion[ing] a workable
    approach" to handling the cases in which Dookhan was the primary
    or confirmatory chemist, I would not spurn the analytical
    approach adopted in Scott. The problem here is the same as it
    was in Scott: the need to craft a fair and timely approach to
    the resolution of these cases.
    5
    balancing these factors as discussed below, I am persuaded that
    the case for a global remedy as advocated by the petitioners is
    compelling.
    1.    Due process rights.   The due process rights at stake
    here, "the opportunity to be heard 'at a meaningful time and in
    a meaningful manner'" (citation omitted), Bridgeman I, 471 Mass.
    at 479, weigh heavily in Scott's remedial calculus for two
    reasons:       the serious and ongoing collateral consequences to the
    class of defendants convicted on the strength of Dookhan's
    tainted evidence; and the necessity to avoid unnecessary delay
    beyond the four years that already have elapsed in providing
    these defendants a "meaningful" opportunity to establish
    prejudice from Dookhan's misconduct.       The court, ante at, paints
    a grim picture of how lives are upended by the serious
    collateral consequences of drug-related convictions.       The
    picture is even more grim when one considers that many, if not
    most, of these defendants have already served their sentences.4
    They have paid their debt to society whether they owed one or
    not.       The years spent incarcerated cannot be restored to these
    4
    An analysis conducted by a data science fellow at the
    American Civil Liberties Union Foundation of Massachusetts found
    that approximately sixty-two per cent of the convictions in the
    cases tainted by Dookhan's misconduct were for possession only
    and that about ninety-one per cent of these cases were resolved
    in the District Court. These statistics support the assumption
    that most defendants have completed their sentences.
    6
    defendants, but a fair and just resolution can make amends.
    What due process requires then is a remedy that is simple, sure,
    and final.   That means a remedy that is uncomplicated by the
    myriad moving parts built into the court's case-by-case model,
    free of the risk that further delay will prolong the only relief
    that realistically can be offered to defendants who have already
    served their sentences.   This interpretation of what due process
    requires at this point in the effort to solve the Dookhan
    problem is supported by Scott and Bridgeman I.
    In Bridgeman I, 471 Mass. at 479, the court declined to
    adopt a global remedy in part based on the "substantial efforts
    that are being made to deal with the impact of Dookhan's
    misconduct."    With at least the prospect of a speedy resolution
    of the cases in which Dookhan was the primary or confirmatory
    chemist, the court was content to delay a more robust remedy to
    allow those efforts to accomplish their purpose.5   Id. at 487.
    Here, however, we have come to an end point in assessing the
    impact of Scott and Charles in resolving the outstanding cases
    of this type.   The district attorneys have identified 24,000
    cases, more or less, that must be adjudicated on the prejudice
    prong of Scott.   Thus, the scope of the current challenge is
    5
    The court observed that "[o]ur decision . . . will go a
    long way in resolving additional concerns that have surfaced and
    in moving these cases forward towards resolution." Bridgeman I,
    471 Mass. at 487.
    7
    clear.    The remedy, in accounting for defendants' due process
    right to a prompt hearing, must have some reasonable prospect
    for immediate resolution of the 24,000 cases to avoid
    exacerbating the serious consequences of delay.    I am not
    persuaded that the court's case-by-case model meets this test in
    circumstances where the defendants' due process rights are
    paramount.
    2.   Integrity of the criminal justice system.   It is beyond
    dispute that Dookhan's misconduct, the details of which have
    spread beyond the legal community,6 has undermined public trust
    in the integrity of the criminal justice system.    In a case such
    as this, coming before the court as a consequence of Dookhan's
    serious corruption of our criminal justice system, the court's
    task is not merely to decide the rights of the parties.       The
    court must also act, within the boundaries of the law, to
    restore the public's faith in the integrity of the courts.
    Unlike the right to counsel crisis in Lavallee, Dookhan's
    misconduct is not a problem of the Legislature's making.      See
    Lavallee, 442 Mass. at 246.   The duty to protect, and restore
    when necessary, the integrity of the criminal justice system
    falls squarely upon the court.
    With no clear sign from the court that it grasps the scope

    Years, Should All Her Cases Be Thrown Out?, Wash. Post, Sept.
    29, 2016.
    8
    of the damage and the need for an approach that will eliminate
    "root and branch"7 all of the attendant consequences, the public
    is left to wonder if the process by which a court imposes the
    sanction of a loss of liberty is fair and just.8   Restoring the
    integrity of the criminal justice system requires that the court
    acknowledge and make amends for the shortcomings in a system
    that permitted Dookhan to "go rogue" for so long without
    detection.9   Those shortcomings call into question the integrity
    of the entire criminal justice apparatus for gathering and
    reporting the evidence that juries rely on in deciding a
    defendant's guilt or innocence.   The perceived legitimacy of
    court-imposed restraints on a defendant's liberty rises or falls
    on the integrity of the evidence.   If the mistrust engendered by
    the individual and institutional failures that produced this
    scandal is allowed to remain, it will have far-reaching adverse

    segregation fourteen years after command to do so in Brown v.

    Over the years, the racial impact of our sentencing
    practices have come under scrutiny. See e.g., The Sentencing
    Project, The Color of Justice: Racial and Ethnic Disparity in
    State Prisons, at 3, 5, 7-8 & n.13, 16-18 (2016). Although
    racial bias has not been documented, members of the public,
    especially those in the communities of color, rarely parse such
    reports in search of the real reason for disparate impact.

    consequences for the ability of our courts to maintain the
    public's faith in the promise of equal justice for all.   Because
    I am not persuaded that the case-by-case model adopted by the
    court can accomplish this essential purpose, this factor weighs
    in favor of the global remedy advocated by the petitioners.
    3.   Efficient administration of justice.   There is no
    question that, despite the best efforts of the parties,
    thousands of defendants affected by Dookhan's misconduct still
    languish without notice of their rights or even a realistic
    opportunity for redress.   The four-year delay in the resolution
    of the cases tainted by Dookhan's misconduct, as discussed
    above, adequately makes the point that the administration of
    justice has been anything but efficient.   Yet, the court gives
    insufficient weight to this factor in adopting a case-by-case
    adjudication model.
    The efficacy of the court's case-by-case model is at best
    questionable, both because it is unworkable and because it is
    likely to perpetuate further delay in providing a remedy to the
    thousands of defendants affected by Dookhan's misconduct.     Not
    only is it lacking in the ability to insure a speedy resolution
    of the 24,000 cases thus tainted, it is vulnerable to failure
    for several practical reasons:   the reliance on voluntary
    cooperation of the district attorneys, and unrealistic
    timetables.
    10
    First, the success of phase one, which anticipates a
    substantial culling of the 24,000 cases, depends entirely on the
    voluntary cooperation of the district attorneys.     Ante at       .
    Understandably, the court has not asserted any authority to
    compel the dismissal of cases.    See Commonwealth v. Pellegrini,
    
    414 Mass. 402
    , 405 (1993) ("Prosecutors have broad discretion in
    determining whether to prosecute a case").     In this respect, the
    court's model does not change the status quo:    the district
    attorneys already have, and have had for the duration of the
    Dookhan crisis, the sole authority voluntarily to dismiss these
    cases.   It is undisputed that the district attorneys have
    cooperated in identifying the defendants presumed to have been
    affected by Dookhan's misconduct.    However, without some basis
    for a reasonable belief that the district attorneys will follow
    through on the suggestion to dismiss thousands of cases with
    prejudice, the court does not inspire confidence in the success
    of the model.
    Second, the timetable for the accomplishment of the various
    phases of the case-by-case model is unrealistic and
    unachievable.   The court acknowledges that "substantial vetting"
    is required under phase one.     Ante at   .   Yet, the district
    attorneys are given only ninety days to sift through the 24,000
    cases that have been connected to Dookhan's misconduct.    If past
    is prologue, and taking into account the delays in getting to
    11
    where we are now, accomplishing this task within the ninety-day
    window adopted for the court's model is highly unlikely.
    Likewise, the thirty-day deadline in phase two for notice to the
    defendants whose cases will not be dismissed without prejudice
    is problematic for the same reason.    To the extent that the time
    frames reflect a calculation that absolute compliance by the
    district attorneys and the Committee for Public Counsel Services
    will adequately accommodate the defendants' due process rights,
    I have no confidence that the court's faith in the practicality
    of the process will be rewarded.   Unless the court is prepared
    to declare that reasonable requests for delay, even those based
    on the impracticality of the timetable, will be denied, the more
    likely scenario is that further indeterminable delay will occur.
    With the defendants' due process right to a prompt hearing
    hanging in the balance, I cannot accept an untimely, and
    ultimately unworkable, case-by-case model as an appropriate
    resolution of the issue before us.
    4.   Other public interests.     None of the other public
    interests at stake here warrants a disposition that prolongs a
    global remedy for the defendants who are presumed to have been
    victims of Dookhan's misconduct.   First, the likelihood that the
    vast majority of the defendants in the cases in which Dookhan
    was the primary or confirmatory chemist have completed their
    sentences mitigates the most compelling public interest at stake
    12
    here:   public safety.   On the other side of the ledger, the
    serious and enduring collateral consequences of these
    convictions remain extant, resulting in manifest injustice to
    those defendants.   The court weighs the rights of the defendants
    "against the necessity for preserving society's interest in the
    administration of justice" and concludes that this factor favors
    the Commonwealth.   Ante at      , quoting Commonwealth v. Cronk,
    
    396 Mass. 194
    , 198-199 (1985).    In my view, this calculation is
    demonstrably erroneous.    Society's interest in the
    administration of justice is hardly served by a remedy that
    defers to the Commonwealth in deciding which, if any, cases are
    to be dismissed with prejudice and, in all other respects,
    depends on the defendants to opt into the scheme to benefit from
    the possibility that the case will be dismissed with prejudice.
    Ante at.
    In sum, the Scott factors weigh heavily in favor of the
    defendants in the cases tainted by Dookhan's misconduct.     The
    scope and egregiousness of that misconduct, combined with the
    four-year delay in providing relief to the defendants affected
    by it, compels a global remedy.    It is difficult to imagine a
    scenario where, faced with the detritus from a scandal of
    similar magnitude, a court would hesitate to order a global
    13
    remedy.   The question comes to mind, "If not now, when?"10
