    APPEALS FROM THE UNITED STATES DISTRICT COURT

    [Hon. Mark L. Wolf, U.S. District Judge]
    ___________________

    appellant.

    July 25, 2013
    SELYA, Circuit Judge.    Few accouterments of our criminal
    justice system are either more fundamental or more precious than
    the accused's right to an impartial jury. That right is threatened
    when — as in this case — juror dishonesty occurs during the voir
    dire process yet is not discovered until well after final judgment
    has entered on the jury's verdict.      But finality is also valuable,
    and not every instance of juror dishonesty requires setting aside
    a previously rendered verdict.
    In   its   present   posture,   this   case   poses   important
    questions about when and under what circumstances the belated
    discovery of juror dishonesty during the voir dire process demands
    vacatur of a jury verdict.      The stakes are high — the jury here
    recommended a death sentence — and the cases that populate this
    arcane corner of the law are muddled.
    The architecture of these appeals is easily described.
    Gary Lee Sampson, the defendant in the underlying criminal case, is
    on death row following his conviction on two counts of carjacking
    (death resulting), a penalty-phase hearing in which the jury voted
    to recommend capital punishment, and an unsuccessful direct appeal.
    See United States v. Sampson (Sampson I), 
    486 F.3d 13
    (1st Cir.
    2007), cert. denied, 
    553 U.S. 1035
    (2008).        In an effort to undo
    his sentence, the defendant brought a habeas petition, see 28
    U.S.C. § 2255, and confronted the district court with a claim that
    juror dishonesty during the voir dire process antecedent to the
    -3-
    penalty-phase hearing deprived him of an impartial jury. Following
    an evidentiary hearing, the district court agreed; it vacated the
    death sentence and ordered a new penalty-phase hearing.      United
    States v. Sampson (Sampson IV), No. 01-10384, 
    2012 WL 1633296
    , at
    *15 (D. Mass. May 10, 2012); United States v. Sampson (Sampson II),
    
    820 F. Supp. 2d 151
    , 202 (D. Mass. 2011).     The government seeks
    immediate review of this decision.
    We first address nuanced questions that cast doubt upon
    our appellate jurisdiction.    Concluding, as we do, that we can
    proceed to the merits of the juror dishonesty claim, we adopt the
    district court's findings of fact, articulate the proper legal
    framework, array the district court's findings of fact against that
    framework, and hold that the defendant's sentence must be set aside
    and a new penalty-phase hearing conducted.
    I.   BACKGROUND
    We rehearse here only those facts that are needed to tee
    up this proceeding. The reader who hungers for more details should
    consult the litany of earlier opinions in this case.     See, e.g.,
    Sampson I, 
    486 F.3d 13
    ; Sampson II, 
    820 F. Supp. 2d 151
    ; United
    States v. Sampson (Sampson III), 
    820 F. Supp. 2d 202
    (D. Mass.
    2011); see also McCloskey v. Mueller, 
    446 F.3d 262
    (1st Cir. 2006).
    In 2001, the defendant engaged in a crime spree that took
    him up the eastern seaboard.   The spree included a series of bank
    robberies in North Carolina and a botched attempt to surrender to
    -4-
    the Federal Bureau of Investigation.            See 
    McCloskey, 446 F.3d at 264
    .       The defendant then perpetrated two Massachusetts carjackings
    that led to the slaying of the carjacked drivers (Phillip McCloskey
    and Jonathan Rizzo).         In each instance, the defendant hitched a
    ride with the victim, forced the victim at knifepoint to drive to
    a secluded area, and committed murder.
    Following these gruesome incidents, the defendant fled to
    New Hampshire in Rizzo's vehicle, forcibly entered a house, and
    strangled the caretaker (Robert Whitney).            He then drove Whitney's
    vehicle to Vermont, abandoned it, and resumed hitchhiking. Another
    Good Samaritan, William Gregory, gave him a lift.                 To repay his
    kindness, the defendant attempted to force Gregory at knifepoint to
    drive to a secluded spot.        This time, however, the intended victim
    escaped.        The defendant later called 911, surrendered to the
    authorities, and confessed.
    On October 24, 2001, a federal grand jury sitting in the
    District of Massachusetts charged the defendant with two counts of
    carjacking,       death   resulting.1     See   18   U.S.C.   §   2119(3).   A
    superseding indictment, deemed necessary to comply with Ring v.
    Arizona, 
    536 U.S. 584
    , 609 (2002), reiterated these charges; and
    1
    Since neither Whitney's murder nor Gregory's carjacking was
    charged by the government, these separate crimes were relevant only
    as aggravating factors for sentencing purposes. Sampson II, 820 F.
    Supp. 2d at 160.
    -5-
    the government served a notice of intent to seek the death penalty
    under the Federal Death Penalty Act (FDPA), 18 U.S.C. § 3593(a).
    In due course, the defendant admitted guilt with respect
    to both counts.         The district court empaneled a death-qualified
    jury   to    consider       the   punishment    to     be   imposed.       See    
    id. § 3593(b)(2)(A); see
    also United States v. Green, 
    407 F.3d 434
    ,
    436-37      (1st     Cir.    2005)   (discussing       "death-qualified      jury"
    requirements).
    The voir dire lasted seventeen days and involved an
    extensive effort to ensure that each juror could — and would —
    decide   the       defendant's    fate   solely   on     the   evidence.         As   a
    preliminary matter, hundreds of potential jurors were required to
    answer   under       oath   seventy-seven      written      questions,   carefully
    designed to elicit information concerning possible bias and life
    experiences that might have subconsciously affected an individual's
    ability to consider the defendant's sentence objectively.                        Many
    venirepersons were excused based on their written responses. Those
    who passed muster were interrogated by the court and the parties.
    Prospective jurors were repeatedly directed to answer all
    questions accurately and honestly.              All were advised that, upon
    request, responses concerning sensitive subjects (whether written
    or oral) would be kept out of the public record.
    After individual questioning, the district court excused
    potential jurors for cause for a wide variety of reasons, including
    -6-
    pretrial exposure to information about the case, attitudes that
    raised questions about impartiality, emotional life experiences
    comparable to matters that would be aired at trial, and responses
    that lacked candor. Eventually, the court seated a jury of twelve,
    along with six alternates.         During the six-week penalty-phase
    hearing, the court learned that two jurors had answered voir dire
    questions inaccurately and replaced them with alternates.
    The penalty-phase hearing turned in large measure on the
    existence   vel   non   of   statutory    and   non-statutory   aggravating
    factors and mitigating factors.          See 18 U.S.C. §§ 3592(a), (c),
    3593(c).    In the end, the jury unanimously recommended that the
    defendant be sentenced to death on both counts. The district court
    followed this recommendation and imposed a sentence of death.          See
    
    id. §§ 3553, 3594;
    United States v. Sampson, 
    300 F. Supp. 2d 275
    ,
    278 (D. Mass. 2004).     The court also denied a flurry of post-trial
    motions.    United States v. Sampson, 
    332 F. Supp. 2d 325
    , 341 (D.
    Mass. 2004).
    On direct review, we affirmed the sentence.         Sampson 
    I, 486 F.3d at 52
    .    The Supreme Court denied the defendant's ensuing
    petition for a writ of certiorari.         See Sampson v. United States,
    
    553 U.S. 1035
    (2008).
    On June 25, 2008, the district court appointed new
    counsel to handle post-conviction proceedings.             See 18 U.S.C.
    § 3599(a)(2).     After some procedural skirmishing, the defendant
    -7-
    filed a petition to vacate, set aside, or correct the judgment.
    See 28 U.S.C. § 2255.           Pertinently, the defendant claimed that he
    was deprived of the right to have his sentence decided by an
    impartial jury because three jurors, designated for the sake of
    anonymity as Jurors C, D, and G, had falsely answered material voir
    dire questions.2
    The district court prudently convened an evidentiary
    hearing to determine the scope and severity of the allegedly
    inaccurate voir dire responses.          This hearing was held over three
    non-consecutive days. The first session concerned all three of the
    contested jurors; the second and third sessions focused exclusively
    on Juror C.
    After careful consideration, the district court concluded
    that       the   inaccuracies    contained    in   Juror   D's   and   Juror   G's
    responses were unintentional errors that did not justify setting
    aside the results of the penalty-phase hearing. Sampson II, 820 F.
    Supp. 2d at 197-201.         The court reached a different conclusion as
    to Juror C, finding that she had repeatedly and intentionally
    provided dishonest responses to important voir dire questions. 
    Id. 2 The defendant's
    section 2255 petition also includes claims
    that he was denied effective assistance of counsel; that the
    government violated its obligations under Brady v. Maryland, 
    373 U.S. 83
    (1963); that the government committed misconduct during the
    grand jury process; that execution would violate his Eighth
    Amendment rights due to his severe mental impairment; and that the
    FDPA and/or the death penalty are unconstitutional. Only the jury
    dishonesty claim is before us.
    -8-
    at 192-97.           The court stated that truthful answers would have
    resulted in Juror C's excusal for cause during voir dire because
    the court would have "inferred bias."                     
    Id. at 165-66, 194-97.
    Consequently, the court set aside the defendant's sentence,3 
    id. at 181-97, and
    on May 10, 2012, ordered a new penalty-phase hearing,
    Sampson IV, 
    2012 WL 1633296
    , at *15.
    At    the   government's     behest,    the    court    subsequently
    certified the following questions for immediate appeal under 28
    U.S.C. § 1292(b): "(1) whether [McDonough Power Equipment, Inc. v.
    Greenwood, 
    464 U.S. 548
    (1984)] requires proof of actual bias or
    implied bias to obtain relief; and, if not, (2) whether [the
    district] court correctly stated the McDonough test."                   Sampson IV,
    
    2012 WL 1633296
    , at *15.
    Recognizing that its right to prosecute an immediate
    appeal       of     the    district     court's    order     was   freighted    with
    uncertainty,         the    government     went    down    three    different   but
    complementary roads.           First, it sought to pursue an appeal of the
    decision as a final order under 28 U.S.C. § 1291 and/or 18 U.S.C.
    § 3731.      Second, it sought to pursue an interlocutory appeal under
    the aegis of 28 U.S.C. § 1292(b).                 Third, the government argued
    that,       should    we   find   the   decision    not    otherwise   immediately
    3
    In a separate opinion, the court summarily dismissed some of
    the defendant's other claims. See Sampson 
    III, 820 F. Supp. 2d at 212-13
    ; see also supra note 2. These rulings need not concern us
    because the court has withheld the entry of orders on them.
    Sampson IV, 
    2012 WL 1633296
    , at *15.
    -9-
    appealable, it nonetheless ought to be reviewed through an exercise
    of advisory mandamus.    See 
    id. § 1651. We
    have consolidated all of
    these initiatives.
    Because resolution of the jurisdictional conundrum is
    logically antecedent to any discussion of the juror dishonesty
    claim, we start there.
    II.    APPELLATE JURISDICTION
    The most conventional assurance of appellate jurisdiction
    is the existence of a final decision.          See 
    id. § 1291 (vesting
    courts of appeals with jurisdiction over "appeals from all final
    decisions of the district courts").          The government asseverates
    that   the   district   court's   decision   vacating    the   defendant's
    sentence and granting him a new penalty-phase hearing is a final
    decision and, thus, is immediately appealable.          The government is
    wrong.
    The beacon by which we must steer is the Supreme Court's
    decision in Andrews v. United States, 
    373 U.S. 334
    (1963).          There,
    the Court held that an order in a section 2255 proceeding that
    vacated a previously imposed sentence and required a new sentencing
    hearing was not a final decision and, thus, not immediately
    appealable.     
    Id. at 339-40. Finality
    does not attach until the
    defendant is sentenced anew.      
    Id. The government contends
    that Andrews is not controlling
    because the decision appealed from here is not an order for
    -10-
    resentencing but, rather, a grant of a new trial which, in a
    section 2255 case, is immediately appealable. See United States v.
    Gordon, 
    156 F.3d 376
    , 378-79 (2d Cir. 1998) (per curiam); United
    States v. Allen, 
    613 F.2d 1248
    , 1251 (3d Cir. 1980).                 In support,
    the government suggests that a penalty-phase hearing in a capital
    case is more akin to a traditional trial than to a resentencing.
    It emphasizes that a jury must be empaneled and certain aggravating
    factors must be proven beyond a reasonable doubt.                See 18 U.S.C.
    § 3593(b)-(c); 
    Ring, 536 U.S. at 602
    , 609.
    To be sure, such similarities do exist, but they are
    superficial.       In any event, the question of whether an order for a
    new penalty-phase hearing in a capital case should be characterized
    as a grant of a new trial as opposed to an order for resentencing
    is not open to us.4         In Andrews, the Supreme Court stated squarely
    that       "[w]here,   as    here,   what     was    appropriately   asked   and
    appropriately granted was the resentencing of the petitioners, it
    is obvious that there could be no final disposition of the § 2255
    proceedings until the petitioners were 
    resentenced." 373 U.S. at 340
    .       We are bound by this precedent.          See Figueroa v. Rivera, 
    147 F.3d 77
    , 81 n.3 (1st Cir. 1998).
    4
    As the government points out, courts sometimes refer to a
    penalty-phase "trial." But the relevant portion of the FDPA, 18
    U.S.C. § 3593(b), describes the penalty-phase proceeding as a
    "sentencing hearing."    We think that Congress's description
    controls.
    -11-
    Given this holding, it is indisputable that the grant of
    a new penalty-phase hearing in a capital case is not a final
    disposition of the proceedings.         "In general, a judgment or
    decision is final for the purpose of appeal only when it terminates
    the litigation between the parties on the merits of the case, and
    leaves nothing to be done but to enforce by execution what has been
    determined."     Parr v. United States, 
    351 U.S. 513
    , 518 (1956)
    (internal quotation marks omitted).       A decision ordering a new
    penalty-phase hearing in a capital case does not satisfy this
    benchmark.    The litigation regarding the defendant's sentence will
    not terminate until after the conclusion of the penalty-phase
    hearing and the court sentences him anew.
    In a variation on this theme, the government suggests
    that the order for a new penalty-phase hearing must be final
    because the last thing that the judge does in an FDPA case is to
    order a penalty-phase hearing (after all, under most circumstances,
    the FDPA requires the jury to determine the sentence).      Thus, the
    government's suggestion goes, an order granting a new penalty-phase
    hearing is necessarily final.
    This suggestion is hopeless.      It may be a jury that
    determines the sentence, but it is the judge who must empanel the
    jury, preside over the new penalty-phase hearing, and impose the
    sentence.    See 18 U.S.C. §§ 3593(d), 3594.    Such a series of steps
    -12-
    to be taken falls comfortably within the ambit of section 2255.
    See 28 U.S.C. § 2255(b).
    In determining that no final decision has yet been
    rendered, we do not write on a pristine page.    Two other courts of
    appeals have confirmed the applicability of Andrews to capital
    penalty-phase hearings and concluded that no final disposition
    exists until the new hearing is complete and the court imposes a
    new sentence.   See United States v. Hammer, 
    564 F.3d 628
    , 632-36
    (3d Cir. 2009); United States v. Stitt, 
    459 F.3d 483
    , 485-86 (4th
    Cir. 2006).   We agree with these courts.
    We likewise reject the government's entreaty that the
    Criminal Appeals Act (CAA), 18 U.S.C. § 3731, which permits an
    appeal from an "order . . . granting a new trial" in a criminal
    case, furnishes a basis for jurisdiction.        The Andrews Court
    specifically held that the CAA "has no applicability" to section
    2255 
    proceedings. 373 U.S. at 338
    .   Andrews is binding on us.
    This brings us to the government's assertion that we have
    jurisdiction under 28 U.S.C. § 1292(b).      By its terms, section
    1292(b) confers discretionary appellate jurisdiction over certain
    interlocutory orders not otherwise appealable.    But this avenue is
    available only when an "order involves a controlling question of
    law as to which there is substantial ground for difference of
    opinion and [] an immediate appeal from the order may materially
    advance the ultimate termination of the litigation."       
    Id. The -13- district
    court found that these conditions had been satisfied and
    certified questions to us under section 1292(b).             Sampson IV, 
    2012 WL 1633296
    , at *11-15.       The government, in turn, filed a petition
    asking that we agree to exercise our section 1292(b) jurisdiction.
    There is, however, a threshold question.           Congress has
    expressly restricted the operation of section 1292(b) to "civil
    action[s]."       28    U.S.C.   §   1292(b).      Whether   a   section   2255
    proceeding may appropriately be characterized as a civil action for
    purposes of section 1292(b) is an unsettled question.                      This
    uncertainty results from pervasive "confusion over whether § 2255
    proceedings are civil or criminal in nature."              Wall v. Kholi, 
    131 S. Ct. 1278
    , 1289 n.7 (2011); see 3 Charles A. Wright et al.,
    Federal Practice and Procedure § 622 (4th ed. updated Apr. 2013).
    Several   cases     indicate     that    section    2255     proceedings   are
    predominantly civil.       See, e.g., Heflin v. United States, 
    358 U.S. 415
    , 418 n.7 (1959); Rogers v. United States, 
    180 F.3d 349
    , 352 n.3
    (1st   Cir.    1999).      Other     cases   indicate   that     section   2255
    proceedings are predominantly criminal.            See, e.g., United States
    v. Martin, 
    226 F.3d 1042
    , 1047 n.7 (9th Cir. 2000); United States
    v. Quin, 
    836 F.2d 654
    , 655-56 n.2 (1st Cir. 1988).
    An advisory committee note suggests that a section 2255
    proceeding should be considered "a continuation of the criminal
    case," rather than a separate civil action.             E.g., Rule 3, Rules
    Governing Section 2255 Proceedings, advisory committee's note.
    -14-
    Some courts have found this controlling, see, e.g., United States
    v. Cook, 
    997 F.2d 1312
    , 1319 (10th Cir. 1993), and others have not,
    see, e.g., United States v. Nahodil, 
    36 F.3d 323
    , 328-29 (3d Cir.
    1994).
    To complicate the matter, some courts have abjured an
    ironclad characterization and have treated section 2255 proceedings
    as hybrid; that is, as civil for some purposes and criminal for
    other purposes.    See, e.g., United States v. Hadden, 
    475 F.3d 652
    ,
    664-65   (4th   Cir.    2007)   (collecting     cases);   United   States    v.
    Fiorelli, 
    337 F.3d 282
    , 286 (3d Cir. 2003) ("[W]hile a § 2255
    motion is deemed a further step in the movant's criminal case, it
    is also considered a civil remedy for purposes of appellate
    jurisdiction."); see also Trenkler v. United States, 
    536 F.3d 85
    ,
    94 (1st Cir. 2008) (making similar observation regarding analogous
    petition for writ of coram nobis).
    There   is    a   smattering    of   direct    precedent;   courts
    occasionally have authorized or refused to authorize the use of
    section 1292(b) in section 2255 cases.              Compare, e.g., United
    States v. Pelullo, 
    399 F.3d 197
    , 202 (3d Cir. 2005) (granting
    interlocutory appeal), with, e.g., Murphy v. Reid, 
    332 F.3d 82
    , 83
    (2d Cir. 2003) (per curiam) (denying interlocutory appeal).                 But
    these courts have done so without elaboration and the decisions
    are, therefore, generally unhelpful.
    -15-
    Given this lack of uniformity, we think that it is an
    open and enigmatic question as to whether section 1292(b) can be
    deployed in a section 2255 case.         In the last analysis, we find it
    unnecessary to answer this vexing question today.                Instead, we
    prefer to take a different route and exercise jurisdiction over the
    underlying juror dishonesty issue through our advisory mandamus
    power.     See United States v. Horn, 
    29 F.3d 754
    , 769-70 (1st Cir.
    1994); see also 16 Charles A. Wright et al., Federal Practice and
    Procedure § 3934.1 (2d ed. updated Apr. 2013) ("Writ review that
    responds to occasional special needs provides a valuable ad hoc
    relief valve for the pressures that are imperfectly contained by
    the    statutes      permitting   appeals     from    final    judgments   and
    interlocutory orders.").
    In pursuance of the All Writs Act, 28 U.S.C. § 1651,
    federal courts "may issue all writs necessary or appropriate in aid
    of their respective jurisdictions and agreeable to the usages and
    principles of law."       This provision allows a court of appeals, in
    certain circumstances, to afford immediate review to otherwise
    unappealable orders.       See, e.g., 
    Horn, 29 F.3d at 769
    .
    The type of writ most appropriate here is advisory
    mandamus.     This writ is reserved for a small class of cases in
    which the usual general mandamus requirements are not met. See 
    id. It is "strong
       medicine    and,   as   such,   should    be   dispensed
    sparingly."    In re Sony BMG Music Entm't, 
    564 F.3d 1
    , 4 (1st Cir.
    -16-
    2009).     We typically exercise this power to settle substantial
    questions of law when doing so would give needed guidance to
    lawyers, litigants, and lower courts.             See 
    Horn, 29 F.3d at 770
    .
    Advisory mandamus is particularly well-suited to the resolution of
    important questions "which, if not immediately addressed, are
    likely to recur and to evade effective review." 
    Green, 407 F.3d at 439
    .
    The   case   at    hand   fits   snugly      within   these    narrow
    confines.    To begin, the case presents an unsettled question of
    systemic significance.        See 
    Horn, 29 F.3d at 769
    -70.             Vacating a
    determination made by a jury that has heard evidence for days on
    end is a serious step.        That is especially true in a capital case:
    "death is [] different," Gardner v. Florida, 
    430 U.S. 349
    , 357
    (1977) (plurality opinion), and repastinating previously plowed
    ground in a capital case exposes the families of his victims and
    the defendant to renewed emotional strain.                   It also entails
    additional costs.
    Additionally, the right at stake in this case deserves
    great respect.      "All would agree that an impartial jury is an
    integral    component    of   a   fair   trial"    and    must    be   "jealously
    safeguard[ed]." Neron v. Tierney, 
    841 F.2d 1197
    , 1200-01 (1st Cir.
    1988).
    Here, moreover, the framework for determining when a new
    trial is warranted because of juror dishonesty is not well-defined.
    -17-
    The leading case on the effect of post-trial discovery of juror
    dishonesty is the Supreme Court's seminal decision in McDonough.
    McDonough involved quite different facts and its teachings are open
    to interpretation.    Further, the district court's reading of
    McDonough is problematic.
    Two other data points are also worthy of note.      First,
    the issue before us will almost certainly recur.    The specter of
    juror dishonesty presents a recurring danger in all cases, civil
    and criminal, capital and non-capital.      A clarification of the
    applicable legal standard would be a great utility in allowing
    courts in future cases to cope with this recurrent problem.
    Second, forbearance on our part might well result in the
    juror dishonesty question evading review.   Let us explain.
    Were we to squander this opportunity to review the
    district court's decision, the new penalty-phase hearing ordered by
    the district court would proceed and a newly empaneled jury would
    recommend the sentence (life imprisonment or death).    If the new
    jury votes for a death sentence, the government would have no
    incentive to appeal — and, indeed, would be foreclosed from doing
    so.   See United States v. Moran, 
    393 F.3d 1
    , 12 (1st Cir. 2004).
    Nor would the defendant appeal the earlier grant of a new penalty-
    phase hearing since it occurred at his behest.   See United States
    v. Angiulo, 
    897 F.2d 1169
    , 1216 (1st Cir. 1990) ("[D]efendants
    -18-
    can[not] properly challenge on appeal a proposal they themselves
    offered . . . .").
    If, however, the newly empaneled jury votes for life
    imprisonment, the district court's order may still evade review.
    The defendant, of course, would not appeal.               For its part, the
    government might be prevented from appealing the earlier decision
    to vacate the death sentence and order a new penalty-phase hearing.
    After all, the Double Jeopardy Clause, U.S. Const. amend. V, cl. 2,
    applies to sentencing hearings in capital cases.            See Sattazahn v.
    Pennsylvania, 
    537 U.S. 101
    , 107-09 (2003).
    A jury's disavowal of the death penalty the second time
    around,    based     on    "findings    sufficient   to     establish    legal
    entitlement to the life sentence," would normally be tantamount to
    an    acquittal    for    double   jeopardy   purposes.     
    Id. at 107-09. Permitting
    the government to appeal after a second death-eligible
    jury has disavowed the death sentence would raise serious double
    jeopardy concerns, and at the least would lead to an incongruous
    result. Indeed, the Court has said that "[t]he policies underlying
    the    Double     Jeopardy   Clause    militate   against    permitting    the
    Government to appeal after a verdict of acquittal."            United States
    v. Wilson, 
    420 U.S. 332
    , 352 (1975).
    Withal, we note that the Double Jeopardy Clause may not
    bar a government appeal following a second penalty-phase jury's
    recommendation of life imprisonment.          As a general rule, no double
    -19-
    jeopardy problem is presented where an "error could be corrected
    without subjecting [the defendant] to a second trial before a
    second trier of fact."        
    Id. at 345. The
    Court has held that
    "[w]hen a jury returns a verdict of guilty and a trial judge (or an
    appellate court) sets aside that verdict and enters a judgment of
    acquittal,     the   Double   Jeopardy    Clause   does   not   preclude   a
    prosecution appeal to reinstate the jury verdict of guilty." Smith
    v. Massachusetts, 
    543 U.S. 463
    , 467 (2005).         The Supreme Court has
    yet to speak directly to this difficult issue.
    We need not enter this quagmire: for present purposes,
    it suffices to say that there is a credible possibility that the
    district court's decision would evade appellate scrutiny were we to
    defer review until after a new penalty-phase hearing is completed.
    If a deferral of review carries with it an appreciable degree of
    danger that the underlying issue will escape review entirely, that
    danger argues in favor of exercising advisory mandamus. See United
    States v. Pleau, 
    680 F.3d 1
    , 4 (1st Cir. 2012) (en banc).
    To say more about the question of appellate jurisdiction
    would serve no useful purpose.      For the reasons elucidated above,
    we deem this case an appropriate one for the exercise of our
    advisory mandamus authority.        Consequently, we proceed to the
    merits.
    -20-
    III.   JUROR DISHONESTY
    The government asserts that the district court erred as
    a matter of law in vacating the defendant's sentence and ordering
    a new penalty-phase hearing.     In the government's view, the court
    misinterpreted the Supreme Court's opinion in McDonough, 
    464 U.S. 548
    (1984), and erected an erroneous legal framework for handling
    post-trial claims of newly discovered juror dishonesty.
    Our standard of review is bifurcated. We review findings
    of raw fact for clear error.    See United States v. George, 
    676 F.3d 249
    , 256 (1st Cir. 2012).         We review the correctness of the
    district court's legal analysis de novo.         See Prou v. United
    States, 
    199 F.3d 37
    , 42 (1st Cir. 1999).
    The government's challenge primarily targets the district
    court's legal regime.       We agree with the government that the
    district court misinterpreted McDonough and erected an erroneous
    framework.     In this instance, however, applying the appropriate
    framework leads to the same result.
    To explain these conclusions, we begin by canvassing the
    district court's findings of fact. We turn next to the appropriate
    legal framework.       Then, we array the facts supportably found
    against the appropriate framework.        Finally, we deal with two
    peripheral arguments advanced by the government.
    -21-
    A. Facts Supportably Found.
    The district court's meticulous factfinding brought to
    light a litany of lies told by Juror C during voir dire.                    We
    rehearse the particulars.
    The post-trial hearing stretched out over three separate
    court days.     During those occasions, the district judge had ample
    opportunity    to    gauge   Juror    C's    credibility   and   evaluate   her
    impartiality.       The court supportably found that Juror C gave false
    answers not only during voir dire but also during the post-trial
    hearing itself.        These false answers related primarily to two
    aspects of Juror C's life.
    The first area about which Juror C persistently lied
    involved her ex-husband, P.          The second involved her daughter, J.5
    The district court supportably found, based on evidence
    adduced during the post-trial proceeding, that P, an employee of
    the United States Postal Service, regularly abused alcohol and
    marijuana.    P rebuffed Juror C's adjurations to seek treatment and
    his continued substance abuse contributed to Juror C's decision to
    obtain a divorce.
    During their marriage, Juror C feared physical abuse as
    P often threatened to harm her.          On one occasion, P menaced Juror
    C with a shotgun.        After her sons took the weapon away, Juror C
    5
    The following summary of the district court's pertinent
    findings is drawn from the court's exegetic opinion in Sampson 
    II, 820 F. Supp. 2d at 181-88
    .
    -22-
    reported the incident to the police. She requested and received an
    abuse prevention order that required P to stay away from her.               P
    violated   this   order,   committing      a   criminal   offense,   when   he
    approached Juror C at their home, chased her into the bedroom, and
    would not let her leave.           P was arrested and prosecuted for
    violating the abuse prevention order.              When Juror C belatedly
    admitted these events, she characterized them as "horrible" and "a
    nightmare."
    Juror C described her experiences with J, whose very
    existence she had failed to acknowledge either in her responses to
    the juror questionnaire or during the voir dire, in much the same
    way.   As Juror C well knew, J at one time held an administrative
    job with the Sanibel Police Department in Florida.               J lost this
    position in 1997, however, when she was placed on probation after
    admitting to the theft of property.            J violated the terms of her
    probation and was given a six-month incarcerative sentence.             Juror
    C vouchsafed her beliefs that J had been treated fairly by the
    authorities during this ordeal.
    J also became a cocaine addict.         Ashamed of J's criminal
    conduct and drug use, Juror C had tried to forget about these
    experiences because thinking of them was "killing" her.              She was
    unwilling to admit that such events could happen in her family.
    Although   Juror    C    signed       the   written   voir    dire
    questionnaire under the pains and penalties of perjury, the proof
    -23-
    adduced during the post-trial proceeding, summarized above, made it
    pellucid that no fewer than ten of her responses were apocryphal.
    We give the flavor of this mendacity by recounting some of the
    responses given by Juror C on the questionnaire.
    C      Question 32 inquired whether Juror C or anyone
    close to her ever had a drug problem.                 She
    answered "no."
    C      Question 34 inquired whether Juror C or anyone
    close to her worked for the federal government.
    She answered "no."
    C      Question 47 inquired as to how many children
    Juror C had.   She indicated that she had only two
    sons.
    C      Question 59 inquired whether Juror C, or anyone
    close to her had ever been a victim of a crime or
    a witness to a crime.     She answered "no."
    C      Question 61 inquired whether Juror C or anyone
    close to her had ever been questioned as part of
    a criminal investigation.        She answered "no."
    C      Question 63 inquired whether Juror C or anyone
    close   to   her   had    ever    been   charged   with
    committing a crime.      She answered "no."
    C      Question 64 inquired whether Juror C knew anyone
    who had ever been in prison.       She answered "no."
    -24-
    C      Question 65 inquired whether Juror C or anyone
    close to her ever had an experience with the
    police in which she (or that other person) was
    treated fairly.   She answered "no."
    C      Question 68 inquired whether Juror C or anyone
    else close to her had ever been employed in law
    enforcement.   She answered "no."
    Each of these answers was false.       Juror C perpetuated these
    falsehoods during the individual voir dire questioning.
    To make a bad situation worse, Juror C continued her
    charade during the initial session of the post-trial hearing. When
    defense counsel attempted to probe her lies about P, she resisted
    that line of inquiry, professing that she did not "want to go into
    all of these [things]."
    On the second day of the post-trial hearing, the truth
    about J began to emerge; Juror C admitted, for the first time, that
    she had a daughter who had been arrested.6
    During the same post-trial session, Juror C testified
    that she did not speak to any of her fellow jurors after the trial
    had concluded.   She also denied any contact with the victims'
    6
    Juror C testified that she wanted to call the court about
    this set of lies after the first post-trial session but did not
    have the telephone number. The court, noting that its telephone
    number was on both her subpoena letter and on the court's general
    website, found this excuse incredible. Sampson 
    II, 820 F. Supp. 2d at 187
    .
    -25-
    families.    These statements were untrue — and Juror C admitted as
    much during the final session of the post-trial hearing.                       Although
    these lies did not occur during voir dire, they are plainly
    relevant to Juror C's credibility and strongly support the district
    court's finding of juror dishonesty.
    Based on this and other evidence, the district court
    found that Juror C had intentionally and repeatedly dissembled
    about P and J because of both the emotional pain involved in
    discussing      these    experiences        and     her    desire   to    avoid     the
    humiliation of sharing them.           Sampson 
    II, 820 F. Supp. 2d at 181
    ,
    197.   This finding has overwhelming support in the record.                       Juror
    C herself acknowledged that she had withheld the information about
    P and J because, when completing the questionnaire, she "didn't
    think [her] personal life had anything to do with [] being a
    juror."   
    Id. at 187. In
    all events, her demeanor while testifying
    evinced   her    emotional      pain   and        humiliation;   she     was    visibly
    distraught    when      discussing     P    and    J,   crying   and     incoherently
    attempting to excuse her mendacity.                 See 
    id. at 184, 185,
    190.
    B.   The Legal Framework.
    We come next to the underlying legal principles that
    govern post-trial claims of newly discovered juror dishonesty.                       It
    is constitutional bedrock that "[i]n all criminal prosecutions, the
    accused shall enjoy the right to a speedy and public trial, by an
    impartial jury."        U.S. Const. amend VI.             An impartial jury is one
    -26-
    "capable and willing to decide the case solely on the evidence
    before it."    
    McDonough, 464 U.S. at 554
    (internal quotation marks
    omitted). The right to an impartial jury is nowhere as precious as
    when a defendant is on trial for his life.           See Ross v. Oklahoma,
    
    487 U.S. 81
    , 85 (1988).
    The FDPA enshrines this right. It requires that the jury
    be unanimous in concluding that the death penalty is justified.
    See   18   U.S.C.   §   3593(d).   If     even   a   single   biased   juror
    participates in the imposition of the death sentence, the sentence
    is infirm and cannot be executed. See Morgan v. Illinois, 
    504 U.S. 719
    , 729 (1992).
    Voir dire is a singularly important means of safeguarding
    the right to an impartial jury. A probing voir dire examination is
    "[t]he best way to ensure that jurors do not harbor biases for or
    against the parties."     Correia v. Fitzgerald, 
    354 F.3d 47
    , 52 (1st
    Cir. 2003).    This goal, however, is not easy to achieve: a person
    who harbors a bias may not appreciate it and, in any event, may be
    reluctant to admit her lack of objectivity.            See 
    McDonough, 464 U.S. at 554
    ; Crawford v. United States, 
    212 U.S. 183
    , 196 (1909).
    As the Supreme Court explained over a century ago, "[b]ias or
    prejudice is such an elusive condition of the mind that it is most
    difficult, if not impossible, to always recognize its existence."
    
    Crawford, 212 U.S. at 196
    .
    -27-
    The   voir   dire    process,     which    is   fluid   rather   than
    mechanical, is frustrated when a prospective juror is dishonest.
    Both the juror's dishonesty and her motivation for that dishonesty
    may cast doubt upon her impartiality.            See 
    McDonough, 464 U.S. at 556
    .       "If the answers to [voir dire] questions are willfully
    evasive or knowingly untrue, the talesman, when accepted, is a
    juror in name only."         Clark v. United States, 
    289 U.S. 1
    , 11
    (1933).
    In McDonough, the Supreme Court spoke to the question of
    when a party is entitled to a new trial after learning that a juror
    failed to disclose material information during the voir dire.                  In
    McDonough, a seated juror in a product liability case, when queried
    during voir dire whether he or his immediate family members had
    ever sustained severe injury in an accident, did not disclose that
    his son had been hurt in a truck tire 
    explosion. 464 U.S. at 549-
    51.    Following a verdict for the defendant and the disclosure of
    this information, the district court denied a motion for a new
    trial.7     The court of appeals reversed.             The Supreme Court ruled
    that the juror's "mistaken, though honest," response did not
    necessitate a new trial.         
    Id. at 555. Emphasizing
    that a party "is
    entitled to a fair trial but not a perfect one," 
    id. at 553 7
           The government argues that standards for review of post-
    conviction claims of juror dishonesty must be more stringent than
    standards for review of a district court's decision during voir
    dire to exclude a juror for bias. Because we base our decision on
    McDonough, we do not discuss this argument.
    -28-
    (internal   quotation   marks   omitted),    the   Court   explained   that
    parties cannot be granted a new trial if the only purpose is "to
    recreate the peremptory challenge process because counsel lacked
    . . . information," 
    id. at 555. The
    McDonough Court distinguished the case before it from
    a situation in which a juror was intentionally dishonest during
    voir dire, and the combination of the undisclosed information and
    such dishonesty demonstrates bias.        To secure a new trial, in the
    latter situation, a party must show "that a juror failed to answer
    honestly a material question" at voir dire, and "then further show
    that a correct response would have provided a valid basis for a
    challenge for cause."   
    Id. at 556. In
    this regard, the Court noted
    that "[t]he motives for concealing information may vary, but only
    those reasons that affect a juror's impartiality can truly be said
    to affect the fairness of a trial."        
    Id. We think it
    follows that, under McDonough, a party
    seeking a new trial based on juror dishonesty during voir dire must
    satisfy a binary test.     See id.; see also Crowley v. L.L. Bean,
    Inc., 
    303 F.3d 387
    , 407 (1st Cir. 2002).           The party must show,
    first, that the juror failed to answer honestly a material voir
    dire question.8   See 
    McDonough, 464 U.S. at 556
    .      For this purpose,
    8
    Of course, a juror, during voir dire, may make honest, but
    mistaken responses. This category includes situations in which,
    for example, the juror misunderstands the wording of the question,
    fails to recall the correct response, or is not asked a question
    that would necessitate disclosure of the relevant information. We
    -29-
    a voir dire question is material if a response to it "has a natural
    tendency to influence, or is capable of influencing," the judge's
    impartiality determination. Neder v. United States, 
    527 U.S. 1
    , 16
    (1999) (internal quotation marks and alteration omitted).
    The second part of the binary test requires a finding
    that a truthful response to the voir dire question "would have
    provided a valid basis for a challenge for cause."        
    McDonough, 464 U.S. at 556
    .    Jurors normally are subject to excusal for cause if
    they   are    biased    or   if   they    fail   to   satisfy   statutory
    qualifications. 2 Charles Alan Wright et al., Federal Practice and
    Procedure § 382 (4th ed. updated Apr. 2013).           In this instance,
    only bias is relevant.
    What constitutes a valid basis for excusal within the
    purview of the binary test is the question that lies at the heart
    of these appeals.      The district court took a categorical approach
    to this question, identifying three such bases: actual bias,
    implied bias, and inferable bias.         Sampson 
    II, 820 F. Supp. 2d at 162-67
    .   We find this categorical delineation unhelpful.
    The McDonough Court saw no need to use pigeonholes of
    this sort.      The Court started by defining impartiality as a
    do not explore here the effect of honest but mistaken voir dire
    responses. For present purposes, it suffices to say that in the
    absence of dishonesty, post-trial relief, if available at all, will
    require a more flagrant showing of juror bias. See Amirault v.
    Fair, 
    968 F.2d 1404
    , 1405 (1st Cir. 1992) (per curiam).
    -30-
    condition that allows a juror to be "capable and willing to decide
    the case solely on the evidence."            
    McDonough, 464 U.S. at 554
    (quoting Smith v. Phillips, 
    455 U.S. 209
    , 217 (1982)).               The flip
    side of impartiality is bias, but the Court warned that "hints of
    bias [are] not sufficient."        
    Id. Instead, only "[d]emonstrated
    bias in the responses to questions on voir dire may result in a
    juror's being excused for cause."          
    Id. This means, of
    course, that cognizable juror bias is a
    valid basis for excusal. But McDonough imposes no requirement that
    cognizable bias be confined to any particular sub-categories.
    Everything depends on the particular circumstances.            Seen in this
    light,   we    think   that   attempting   to    classify   biases   in   sub-
    categories is likely to do more harm than good.             Consequently, we
    eschew the district court's formulation and hew to the line plotted
    by the McDonough court.       
    Id. at 555-56. Refraining
    from a categorical approach makes eminently
    good sense: after all, bias is not a pedagogical conception but
    rather a state of mind.       To reveal the existence of this state of
    mind, "the Constitution lays down no particular tests and procedure
    is not chained to any ancient and artificial formula."                 United
    States v. Wood, 
    299 U.S. 123
    , 145-46 (1936).
    When all is said and done, the existence vel non of a
    valid basis for a challenge for cause is not a matter of labels.
    Any inquiry into potential bias in the event of juror dishonesty
    -31-
    must be both context specific and fact specific.            The outcome of
    this inquiry depends on whether a reasonable judge, armed with the
    information that the dishonest juror failed to disclose and the
    reason behind the juror's dishonesty, would conclude under the
    totality of the circumstances that the juror lacked the capacity
    and the will to decide the case based on the evidence (and that,
    therefore, a valid basis for excusal for cause existed).                   See
    
    McDonough, 464 U.S. at 554
    .      The party seeking to upset the jury's
    verdict has the burden of showing the requisite level of bias by a
    preponderance of the evidence.         See DeBurgo v. St. Amand, 
    587 F.3d 61
    , 71 (1st Cir. 2009).
    A number of factors may be relevant in determining
    whether a juror has both the capacity and the will to decide the
    case solely on the evidence.      This compendium may include (but is
    not limited to) the juror's interpersonal relationships, see, e.g.,
    United States v. Colombo, 
    869 F.2d 149
    , 151-52 (2d Cir. 1989);
    United States v. Scott, 
    854 F.2d 697
    , 698-700 (5th Cir. 1988); the
    juror's ability to separate her emotions from her duties, see,
    e.g., Dennis v. Mitchell, 
    354 F.3d 511
    , 518-19, 521 (6th Cir.
    2003); Burton v. Johnson, 
    948 F.2d 1150
    , 1158-59 (10th Cir. 1991);
    the similarity between the juror's experiences and important facts
    presented at trial, see, e.g., United States v. Torres, 
    128 F.3d 38
    , 47-48 (2d Cir. 1997); 
    Burton, 948 F.2d at 1158-59
    ; the scope
    and   severity   of   the   juror's    dishonesty,   see,   e.g.,   Dyer    v.
    -32-
    Calderon, 
    151 F.3d 970
    , 983-84 (9th Cir. 1998) (en banc); 
    Scott, 854 F.2d at 699-700
    ;   and   the   juror's   motive   for   lying,   see
    
    McDonough, 464 U.S. at 556
    ; Skaggs v. Otis Elevator Co., 
    164 F.3d 511
    , 516 (10th Cir. 1998).           Although any one of these factors,
    taken in isolation, may be insufficient to ground a finding of a
    valid basis for a challenge for cause, their cumulative effect must
    nonetheless be considered.         See United States v. Perkins, 
    748 F.2d 1519
    , 1532-33 (11th Cir. 1984).
    C.   Integrating Fact and Law.
    It remains for us to evaluate the impact of the facts
    supportably found in terms of the appropriate legal framework. But
    there is a rub: the district court misunderstood the applicable
    legal framework, instead creating a new sub-category that it called
    "inferable bias" to serve as the cornerstone of its conclusion that
    Juror C's dishonesty necessitated a new penalty-phase hearing. See
    Sampson 
    II, 820 F. Supp. 2d at 165-67
    , 192-96.
    The district court's mistaken view of the law, however,
    does not require us to throw out the baby with the bath water.
    Where, as here, a trial court, notwithstanding its misapprehension
    of the law, makes a detailed set of subsidiary findings as to the
    raw facts, those findings sometimes may be subject to reuse.               See
    Societe Des Produits Nestle, S.A. v. Casa Helvetia, Inc., 
    982 F.2d 633
    , 642 (1st Cir. 1992) (concluding that, in a case in which the
    trial court supportably found the facts but applied the wrong rule
    -33-
    of law, court of appeals had the authority, in lieu of remand, to
    array the findings against the correct legal standard); United
    States v. Mora, 
    821 F.2d 860
    , 869 (1st Cir. 1987) (similar).               This
    is such a case.
    We turn now to the task of arraying the lower court's
    factual findings against the correct legal framework.                The first
    part of the binary test focuses on whether Juror C failed to answer
    honestly one or more material voir dire questions.                 The district
    court's factual findings make manifest that this benchmark was
    satisfied. Juror C understood her duty to be truthful in answering
    the voir dire questionnaire, yet her certification under the pains
    and penalties of perjury was knowingly false.               As Juror C later
    admitted, she had been deliberately dishonest when answering the
    questions that called for information about the exploits of P and
    J.
    The materiality of the questions that Juror C answered
    dishonestly      is       nose-on-the-face   plain.         Each      question,
    individually, was designed to solicit information that potentially
    could   impugn        a   juror's   impartiality;     and    the     questions,
    collectively, bore heavily on that subject.           Questions that go to
    the heart of juror impartiality are unarguably material to the voir
    dire process.
    This brings us to the second element of the binary test:
    whether a reasonable judge, armed with the information that the
    -34-
    dishonest juror failed to disclose and the reason behind the
    juror's dishonesty, would conclude under the totality of the
    circumstances that the juror lacked the capacity and the will to
    decide the case based on the evidence (and that, therefore, a valid
    basis for excusal for cause existed).           We conclude that this
    showing was made.       Our conclusion rests on three cross-braced
    pillars: (i) Juror C's habitual dissembling; (ii) the intense
    emotions   Juror   C   exhibited   when   belatedly   relating   her   life
    experiences involving P and J; and (iii) the similarities between
    Juror C's unreported life experiences and the evidence presented
    during the penalty-phase hearing. We comment briefly about the way
    in which these pillars interact to demonstrate a valid basis for
    excusal for cause.
    Although juror dishonesty, by itself, is not sufficient
    to demonstrate bias, it can be a powerful indicator of bias.            See
    
    Colombo, 869 F.2d at 151
    ; 
    Perkins, 748 F.2d at 1532-33
    .                Here,
    Juror C lied repeatedly in the voir dire questionnaire and directly
    to the court.      This parlous pattern of persistent prevarication
    supports an inference that Juror C's ability to perform her sworn
    duty as an impartial juror was compromised from the start.
    What is more, Juror C's repetitive acts of dishonesty
    illustrate the powerful emotions she harbored about P and J.            See
    
    Burton, 948 F.2d at 1159
    .     To put this proposition in bold relief,
    Juror C left no doubt but that she would rather lie to the court
    -35-
    than discuss these painful life experiences.                   The record fully
    supports the district court's observation that, even years after
    the penalty-phase hearing, her "shame and embarrassment were so
    intense   that    she   could    not   discuss    those       matters   candidly,
    unemotionally or, often, coherently."            Sampson 
    II, 820 F. Supp. 2d at 193
    .
    This display of emotional distress illuminates Juror C's
    motives for lying. The McDonough Court made clear that "only those
    reasons [for lying] that affect a juror's impartiality can truly be
    said to affect the fairness of a 
    trial." 464 U.S. at 556
    .          Here,
    it is far more likely than not that — as the district court found
    — Juror C's reasons for lying about P and J impaired her ability to
    decide the case solely on the evidence. The magnitude of Juror C's
    emotional distress strongly suggests that it would have been a
    Sisyphean task for her to separate the evidence presented at the
    penalty-phase hearing from her intense feelings about her own life
    experiences.
    Juror C's inability to remain detached is especially
    troubling in this case because of the similarity between her
    distress-inducing life experiences and the evidence presented
    during    the    penalty-phase    hearing.        When    a    juror    has    life
    experiences that correspond with evidence presented during the
    trial, that congruence raises obvious concerns about the juror's
    possible bias.     See 
    Torres, 128 F.3d at 47-48
    ; Burton, 948 F.2d at
    -36-
    1158-59.     In   such    a   situation,       the   juror   may    have   enormous
    difficulty separating her own life experiences from evidence in the
    case.    For example, it would be natural for a juror who had been
    the victim of a home invasion to harbor bias against a defendant
    accused of such a crime.
    In the case at hand, the overlap is striking. We offer a
    few illustrations.
    For   one    thing,   the    jurors      heard   evidence      that   the
    defendant threatened bank tellers at gunpoint during the string of
    North Carolina bank robberies and his murder victims at knife
    point.     For her part, Juror C was frequently threatened by her
    then-husband once with a shotgun and other times with his fists.
    The shotgun threat occurred in fairly close temporal proximity to
    the empanelment of the jury (three years or so).                   See Sampson 
    II, 820 F. Supp. 2d at 185
    .       These parallels raise a serious concern as
    to whether an ordinary person in Juror C's shoes would be able to
    disregard her own experiences in evaluating the evidence.
    For another thing, the government presented evidence
    during the penalty-phase hearing that the defendant had substance
    abuse problems — problems that contributed, inter alia, to the
    dissolution of his marriage.        For her part, Juror C was forced to
    deal with the substance abuse of both her husband and her daughter.
    Indeed, P's substance abuse was a catalyst for the dissolution of
    Juror C's marriage.       These parallels raise a serious concern as to
    -37-
    whether an ordinary person in Juror C's shoes would be able to
    disregard her own family's involvement with substance abuse and
    avoid a bias against the defendant on account of his substance
    abuse.
    Then, too, the jury heard evidence during the penalty-
    phase hearing anent the defendant's criminal history, including his
    incarceration    for   robbery.     Analogously,    Juror    C's   daughter
    committed larceny and was incarcerated as a result.                Juror C
    testified that she was deeply ashamed of her daughter's immurement.
    These parallels raise a serious concern as to whether an ordinary
    person in Juror C's shoes would be able to disregard J's troubles
    with the law and avoid a bias against the defendant on this
    account.9   This concern is magnified by the powerful emotions that
    Juror C displayed about her parallel life experiences.
    We   conclude   that   if   fully   informed    of   Juror   C's
    willingness to lie repeatedly, her fragile emotional state, her
    past experiences with P and J, and the similarities between those
    experiences and the evidence to be presented during the penalty-
    phase hearing, any reasonable judge would have found that the
    cumulative effect of those factors demonstrated bias (and, thus, a
    valid basis for excusal for cause).             Indeed, the court below
    9
    In this regard, Juror C might also have identified with the
    defendant's parents, whom the penalty-phase evidence depicted as
    being ashamed of their child (abandoning him and refusing to
    cooperate with his attorneys). See Sampson 
    II, 820 F. Supp. 2d at 158
    , 181.
    -38-
    excused a number of prospective jurors for cause on less compelling
    grounds.     Thus, the defendant was deprived of the right to an
    impartial jury and is entitled to a new penalty-phase hearing.
    D.   Attempts at Avoidance.
    As a last resort, the government tries to catch lightning
    in   a   bottle.   It    argues   that   even   if   Juror   C's   dishonesty
    constitutes a valid basis for dismissal for cause, the district
    court had no right to vacate the defendant's sentence and order a
    new penalty-phase hearing.        It advances two theories.          We find
    neither theory persuasive.
    To begin, the government asserts that the district court
    developed a new constitutional rule when it based the grant of a
    new penalty-phase hearing on "inferable bias."          The application of
    this new rule, the government's thesis runs, transgressed the non-
    retroactivity principle for criminal cases under collateral review.
    See Teague v. Lane, 
    489 U.S. 288
    , 310 (1989) (plurality opinion)
    (holding that a criminal defendant is generally not entitled to
    collateral relief if granting that relief would require the court
    to apply a new constitutional rule implicating criminal procedure);
    Ferrara v. United States, 
    456 F.3d 278
    , 288 (1st Cir. 2006) (same).
    This proposition is rendered moot by our rejection of the
    district court's "inferable bias" formulation. The legal framework
    that we have used does not embody any new constitutional rule of
    criminal procedure but, rather, merely applies the rule laid down
    -39-
    by the Supreme Court in McDonough to the circumstances of the case
    at hand.      Such a course of action does not offend the non-
    retroactivity principle.      After all, a case is deemed to announce
    a new constitutional rule of criminal procedure only if the result
    is not driven by precedent that existed at the time of the
    decision. See 
    Teague, 489 U.S. at 301
    (plurality opinion). A case
    does not announce a new constitutional rule of criminal procedure
    when it is "merely an application of the principle that governed"
    a prior decision to a different set of facts.                   
    Id. at 307 (plurality
    opinion; internal quotation marks omitted); accord
    Chaidez v. United States, 
    133 S. Ct. 1103
    , 1107 (2013); O'Dell v.
    Netherland, 
    521 U.S. 151
    , 156 (1997).
    If more were needed — and we do not think that it is —
    the government's assertion of the non-retroactivity principle is
    untimely. The government makes this argument for the first time on
    appeal.       A   Teague   defense   is     not   jurisdictional,     and   the
    government's failure to raise such a defense in a timeous manner
    constitutes a waiver.      See 
    Ferrara, 456 F.3d at 289
    .         Because the
    government failed to interpose this defense below, it is waived.
    The government's second attempt at avoidance is no more
    convincing.        It   asserts   that      because   the   defendant    seeks
    remediation on collateral review, constitutional error does not
    entitle him to relief in the absence of actual prejudice.                   See
    Brecht v. Abrahamson, 
    507 U.S. 619
    , 637-38 (1993).              Building on
    -40-
    this foundation, the government insists that there has been no
    showing of actual prejudice here.
    The government is wrong.    There is more than sufficient
    evidence of prejudice in the record to entitle the defendant to
    relief,10 given the extent of Juror C's bias and the capital
    penalty-phase proceedings in which she participated.         As the
    Supreme Court said in United States v. Martinez-Salazar, 
    528 U.S. 304
    (2000), where a biased juror sits on a jury that sentenced a
    defendant to death and the issue was properly preserved, the
    sentence would have to be overturned, 
    id. at 316 (citing
    Ross, 487
    U.S. at 85
    ); see also 
    Morgan, 504 U.S. at 729
    (stating that "[i]f
    even one [biased] juror is empaneled and the death sentence is
    imposed, the State is disentitled to execute the sentence").
    IV.   CONCLUSION
    This case is a stark reminder of the consequences of
    juror dishonesty.    Jurors who do not take their oaths seriously
    threaten the very integrity of the judicial process.     The costs,
    whether measured in terms of human suffering or monetary outlays,
    are staggering.    But the ultimate lesson that this case teaches is
    that the protections afforded by the Constitution and laws of the
    10
    In view of the existence of actual prejudice, we need not
    reach the defendant's contention that the doctrine of structural
    error applies and obviates any need for a showing of actual
    prejudice. See 
    Brecht, 507 U.S. at 629-30
    .
    -41-
    United States are, in the end, sufficient to protect against even
    the most insidious threat.
    We need go no further. For the reasons elucidated above,
    we dismiss the government's two appeals.   Exercising our advisory
    mandamus power, we conclude — as did the district court — that the
    death sentence must be vacated and a new penalty-phase hearing
    undertaken.   Accordingly, we deny the government's request for the
    issuance of an extraordinary writ.
    So Ordered.
