Judge STRAUB, in a separate opinion, concurs in the judgment and in the majority opinion in part. KEARSE, Circuit Judge: Defendant David Parse appeals from a judgment entered in the United States District Court for the Southern District of New York following a jury trial before William H. Pauley III, Judge, convicting him on one count of mail fraud, in violation of 18 U.S.C. §§ 1341 and 2, and on one count of corruptly endeavoring to obstruct and impede the administration of the internal revenue laws, in violation of 26 U.S.C. § 7212(a). Parse was sentenced principally to 42 months’ imprisonment, to be followed by three years of supervised release, and was ordered to forfeit $1,000,000 and to pay $115,830,267 in restitution. On appeal, he contends principally that he should have been granted a new trial on the ground of newly discovered evidence of juror bias; he challenges the district court’s denial of his posttrial motion pursuant to Rule 33 of the Federal Rules of Criminal Procedure for that relief, made jointly with his codefendants against whom the jury had returned verdicts of guilty, in light of postverdict evidence establishing that one of the jurors had lied on voir dire, concealed relevant information, and was actually biased against the defendants. The district court granted the new-trial motion of Parse’s codefendants; but it denied the motion of Parse, finding that his attorneys either knew of the juror’s misconduct prior to the verdict or failed to act with reasonable diligence based on the information they had, and that Parse had thus waived his right to an impartial jury. Parse also contends that the evidence was insufficient to support the jury’s verdicts against him, and he challenges certain of the instructions given to the jury. Finding merit in Parse’s challenge to the denial of his Rule 33 motion, but not in his sufficiency challenges, we vacate the judgment and remand for a new trial of the counts on which Parse was convicted. I. BACKGROUND Parse and several others were indicted in 2009 and were ultimately charged with one count of conspiracy to defraud the United States and to commit mail fraud, wire fraud, and tax evasion, in violation of 18 U.S.C. § 371, and with multiple substantive counts of tax evasion and other tax-related offenses in connection with the creation of a series of tax shelters “designed and marketed by [a law firm and an accounting firm] to take advantage of Internal Revenue Code ... loopholes so taxpayers could claim non-economic tax losses to avoid taxes they otherwise would have owed” (Parse brief on appeal at 7). Parse was a broker employed by an investment banking firm that executed transactions for implementation of the shelters. In the spring of 2011, Parse was tried along with four of his codefendants: Paul Daugerdas and Donna Guerin, who were attorneys at the law firm; Denis Field, a member of the accounting firm; and Craig Brubaker, a broker at the investment bank that employed Parse. Following a three-month trial at which 41 witnesses testified and some 1,300 exhibits were admitted, the jury on May 24 returned a split verdict. It found Parse guilty on two counts — the substantive mail fraud and obstruction charges described above — and found him not guilty on the other four counts against him. (See Trial Transcript (“Tr.”) 9153-54, 9159-63.) It found Daugerdas guilty on all 24 counts against him; found Guerin guilty on all 12 counts against her; found Field guilty on all 7 counts against him; and found Brubaker not guilty on any of the counts against him. (See id. at 9153-63.) A. The District Court’s Findings of Juror Misconduct In July 2011, Parse, Daugerdas, Guerin, and Field moved pursuant to Fed. R.Crim.P. 33(a) for a new trial on the ground that one of the jurors, Catherine M. Conrad — “Juror No. 1” (or “Conrad”) — had lied and withheld material information during voir dire and was biased against defendants. The motion was made some two weeks after the government disclosed to defendants and the district judge a letter it had received from Conrad shortly after the return of the verdict. (See Part I.A.2. below.) Following completion of the parties’ submissions on the motion, including information from Parse’s attorneys as to their earlier suspicions about Conrad (see Part I.B. below) and an evi-dentiary hearing, the district court, in a thorough opinion, see United States v. Daugerdas, 867 F.Supp.2d 445 (S.D.N.Y.2012) (“Daugerdas ”), found it “undisputed that Conrad lied extensively during voir dire and concealed important information about her background,” id. at .451. The district court’s description of the voir dire proceedings concerning Conrad and the information about her that was unearthed in Parse’s attorneys’ investigations, as to which there is no material dispute, included the following. 1.Conrad’s Voir Dire For jury selection, an initial venire of 450 prospective jurors had been assembled; “the Jury Department provided counsel with a jury roll identifying the prospective jurors in the venire, and listing a ‘Catherine M. Conrad’ with a Bronxville residence.” Daugerdas, 867 F.Supp.2d at 449. Preliminary procedures winnowed the number of prospective jurors from 450 to approximately 175; the panel of 175 was sworn in for voir dire. In discussing defendants’ new-trial motion, the district court stated, quoting the transcript of the voir dire proceedings, that the court had posed a number of questions to the panel as a whole, including five that are relevant to this motion: 1. “Do any of you know or have you had any association, professional, business, social, direct or indirect, with any member of the staff of the United States Attorney’s Office for the Southern District of New York, the United States Department of Justice, or the Internal Revenue Service? Has anybody had any dealings with the U.S. Attorney’s Office, the Department of Justice, or the IRS?” (Trial Tr. 84-85.) 2. “Are you or [has] any member of your family ever been a party to [a] lawsuit, that is, a plaintiff or a defendant in a civil case or a criminal case? ” (Trial Tr. 105.) 3. “Have any of you or a close relative ever been involved or appeared as a witness in any investigation by a federal or state grand jury or any congressional committees or state legislative bodies or licensing authorities or planning boards?” (Trial Tr. 107.) 4. “Have any of you ever been a witness or a complainant in any hearing or trial, whether it be in the state or federal courts?” (Trial Tr. 108.) 5. “[H]ave you or any member of your family or any very close personal friend ever been arrested or charged with a crime? ” (Trial Tr. 118.) Conrad responded affirmatively to only two of these questions. In response to the first question, Conrad offered that her father “works for DOJ across the street” as “an immigration officer.” (Trial Tr. 85.) She then assured this Court that his position would not affect her ability to be fair and impartial. (Trial Tr. 85.) In response to the second question, Conrad stated that she “was a plaintiff in a personal injury negligence case ... pending” in Bronx Supreme Court. (Trial Tr. 105.) Again, she represented that her personal injury action would not interfere with her ability to serve as a juror. (Trial Tr. 106.) Conrad did not provide any additional information or any other affirmative answers to questions posed to the group. Daugerdas, 867 F.Supp.2d at 449-50 (emphases ours). The district court had proceeded to ask further, more detailed, questions of the prospective jurors individually. THE COURT: .... Ms. Conrad .... would you tell us what neighborhood you reside in? CONRAD: Bronx Village [sic] [Bronxville] in Westchester. THE COURT: How long have you lived at your current address? CONRAD: My whole life. THE COURT: Do you work outside the home? CONRAD: No. I’m a stay-at-home wife. THE COURT: .... What is the highest level of education you’ve attained? CONRAD: I have a BA in English literature [and] classics, and I studied archeology abroad. Id. at 450-51 (quoting voir dire transcript at 203-04 (emphases ours)). The court noted that it had offered prospective jurors the opportunity to come to the bench for a sidebar with respect to any information that they preferred not to give publicly. Several prospective jurors took advantage of that offer, but Conrad sought no such sidebar and provided no other information in response to these questions. See id. at 450. The court found that Conrad in voir dire had lied about, among other matters, her own background and that of her husband. Conrad lied about her educational, professional, and personal background. While she informed the Court that her highest level of education was a bachelor’s degree, she in fact obtained her juris doctorate from Brooklyn Law School in 1997 and was admitted to practice law in New York in January 2000. ... Further, although she informed the Court that she was a “stay-at-home wife,” she had practiced law for some time until the New York Supreme Court Appellate Division, First Department (the “Appellate Division”) suspended her law license. ... And the day before she was sworn as a prospective juror, she sought to have her law license reinstated. Conrad answered under oath that she owned a home and lived in Bronxville ' in Westchester County “all my life. ” (Trial Tr. at 203.) That, too, was a lie. In fact, Conrad rented an apartment and lived on Barker Avenue in the Bronx for years. Daugerdas, 867 F.Supp.2d at 452 (emphases ours); see also id. at 458 (finding that on the juror qualification questionnaire completed under oath prior to voir dire, Conrad “lied” in stating that “her permanent address was in Bronxville, New York,” thereby enabling her to collect “collect[ ] an additional $765 in travel expenses based on her use of a Westchester zip code”). As to the concealment by Conrad of the fact that she had been educated as and practiced as an attorney, the court noted that Conrad also hid the fact that she was the subject of an investigation and disciplinary proceedings conducted by the Departmental Disciplinary Committee (the “Disciplinary Committee”) of the Appellate Division. In December 2007, the Appellate Division suspended Conrad from the practice of law for failing “to cooperate with the [Disciplinary] Committee’s investigation into two complaints alleging professional misconduct which threatens the public interest.” In the Matter of Catherine M. Conrad (“2007 Suspension Order”), 48 A.D.3d 187, 188, 846 N.Y.S.2d 912 (1st Dep’t 2007). According to one complaint, Conrad “violated court orders and failed to appear as directed, ultimately resulting in the dismissal of the action.” 2007 Suspension Order, 48 A.D.3d at 188, 846 N.Y.S.2d 912. According to the second complaint, she failed to oppose an order to show cause, resulting in an adverse ruling against her client. 2007 Suspension Order, 48 A.D.3d at 188, 846 N.Y.S.2d 912. In response to her state bar suspension, on January 4, 2008, Conrad was suspended from the bar of the United States District Court for the Southern District of New York. See In re Catherine M. Conrad, No. M-2-238 (JSR) (S.D.N.Y. Jan. 4, 2008); see also Local Civ. Rule 1.5(b)(5) (violations of the New York State Rules of Professional Conduct are grounds for discipline, including suspension). On January 29, 2008, Conrad was suspended from the bar of the United States District Court for the Eastern District of New York. See In re Catherine M. Conrad, No. MC-08-010 (BMC) (E.D.N.Y. Jan. 29, 2008). Daugerdas, 867 F.Supp.2d at 453. With respect to the fact that Conrad was seeking to practice law again, the court found that her “application for reinstatement,” filed on the day before voir dire began, was riddled with falsehoods. She failed to report that she had not paid a fine imposed on her by the Eastern District of New York, even though the application required that disclosure. (See ... Letter from Chief Counsel Jorge Dopico of the Disciplinary Committee, dated Aug. 9, 2011 (“Dopico Letter”), at 3.) She also stated, in response to a direct question on the application, that she had not used any other names, even though she had used the name “Catherine Rosa” when arrested in May 2009. (Dopico Letter, at 5). Finally, she stated that she had no arrests or convictions since her suspension in 2007, when in fact she had pleaded guilty to shoplifting charges in October 2009. (Dopico Letter, at 5.) Daugerdas, 867 F.Supp.2d at 454. The court went on to recount other instances of Conrad’s misrepresentations as to her criminal history: According to New York and Arizona criminal records, Conrad was arrested and charged with crimes on at least five occasions.... On April 17, 1998, Conrad was arrested in New York and charged with driving while intoxicated, reckless endangerment, leaving the scene of an accident, assault, resisting arrest, and harassment. ... On October 21, 1998, she pleaded guilty to the misdemeanor driving while intoxicated charge.... Shortly before that plea, on September 23, 1998, she was arrested again and charged with criminal contempt and aggravated harassment. She pleaded guilty to these misdemeanors on May 17, 1999, and was sentenced to three years probation .... On August 4, 2007, Conrad was arrested in Arizona for disorderly conduct. ... At approximately 5:00 a.m., local police responded to a call from Conrad, complaining of a domestic dispute at a motel with Rosa, who she had married six weeks earlier.... As the police investigated, she was highly disruptive, disturbed other hotel guests, and ignored the responding officers’ requests to quiet down. Ultimately, the officers placed Conrad under arrest and booked her at the Navajo County Jail on charges of disorderly conduct. On August 7, 2007, Conrad was released on her own recognizance and ordered to appear for arraignment on August H.... She failed to appear and an arrest warrant was issued.... It appears that warrant remains outstanding. In May 2009, Conrad was arrested in New York on two separate occasions for shoplifting.... On May 6, she was arrested for shoplifting $47 worth of groceries from a Yonkers supermarket.... Days later, on May II, she was arrested again for shoplifting approximately $27 worth of goods from a New Rochelle supermarket_Both charges were resolved by a plea to a single count of petit larceny.... Under her plea agreement, Conrad was placed on probation for three years.... A July 14 probation report noted that Conrad was in an outpatient treatment program for alcoholism. ... An October probation report indicated that the outpatient program expelled her because of her continued use of alcohol and recommended a four-week inpatient program.... While it is unclear whether she participated in that program, Conrad was on probation during voir dire and throughout the entire trial of this case. Daugerdas, 867 F.Supp.2d at 454-55 (emphases added). In Conrad’s voir dire, she had been asked whether there were other members of her household and had responded that she lived with her husband, whom she described as being retired. When the court asked “What is he retired from?” Conrad responded, “He owns some bus companies.” Id. at 450 (internal quotation marks omitted). The district court found that in fact “Conrad’s husband, Frank J. Rosa (‘Rosa’), is a career criminal,” id. at 454, and that her response was a “fabrication ... designed to conceal his criminal past,” id. at 455: According to public records, from 1980 through the late 1990s, Rosa was convicted of at least nine criminal offenses .... Among other crimes, he was convicted of receiving stolen property, criminal contempt, possession of a controlled substance, forgery, and illegal possession of a firearm.... He has been incarcerated on numerous occasions and served a seven year sentence in Northern State Prison in New Jersey. Id. 2. Conrad’s Posttrial Letter to the Government The jury’s verdict in the present case was returned on May 24, 2011. On May 25, 2011, Conrad wrote a letter to the Assistant United States Attorney who led the government’s trial team (the “May Letter”), praising its performance at trial but .lamenting the acquittals of Parse. The district court described the letter as follows: Conrad authored a two-page typewritten letter dated May 25, 2011 to Assistant United States Attorney Stanley J. Okula, Jr. (“Okula”) praising the Government’s prosecution of the case (the “May Letter”). The May Letter was postmarked May 28. On June 22, the Government forwarded the May Letter to the Court and defense counsel.... In her letter, Conrad wrote, “I thought that you [i.e., Okula], Ms. Davis and Mr. Hernandez [other members of the Government’s trial team] did an outstanding job on behalf of Our Government.” In describing the jury’s role, she stated that “I did feel that we reached a fair and just verdict based on the case, facts and evidence presented to us.” She further explained that “we did have qualms with Mr. David Parse. I solely held out for two days on the conspiracy charge for him I wanted to convict 100%, (not only on that charge)— but on Tuesday, May 21, 2011, we had asked for the Judge’s clarification of ‘willfully’ and ‘knowingly’, I believe, and I had to throw in the towel. ” Conrad went on for an additional two paragraphs discussing the strengths and weaknesses of the Government’s case against Parse, the effectiveness of expert witness testimony, the persuasiveness of certain evidence, and the credibility of fact witnesses. She concluded her letter by writing, “I have learned, the saying a ‘federal case’ is REALLY a ‘federal case’, and I feel privileged to have had the opportunity to observe la creme de la creme — KUDOS to you and your team! ! !” Daugerdas, 867 F.Supp.2d at 452 (capitalization in May Letter) (italics ours). {See also May Letter at 2 (“Mr. Parse presented a conundrum — not for me, but for the other eleven.”).) Defendants’ motion for a new trial stated that Conrad’s May Letter had prompted them to investigate Conrad and that they thereby learned of her disciplinary proceedings and her status as a suspended lawyer by searching public records. The court eventually scheduled an evidentiary hearing with respect to Conrad’s conduct (see Part I.A.3. below) and with respect to the timing of the parties’ knowledge of her misconduct (see Part I.B. below). 3. The Evidentiary Hearings on Conrad’s Conduct The evidentiary hearing was scheduled for February 15-16, 2012. In the meantime, the court ordered Conrad to appear in person on December 20, 2011 — with the parties agreeing to participate by telephone — in order for the court to instruct Conrad as to her constitutional rights and to appoint an attorney for her if she could not afford one: The Court directed the U.S. Marshals to serve Conrad with a copy of the order to appear. The marshals served Conrad at her apartment in the Bronx, and on receiving the order, she stated, “I think I know what this is about, I failed to disclose that I’m a lawyer, but they never asked, so I didn’t lie.” Conrad recognized a photograph of herself that the marshals carried and said, “that picture must be from my rap sheet.” (GX 3500-2, U.S. Marshals Report dated Dec. 16, 2011.) Daugerdas, 867 F.Supp.2d at 455. At the December hearing, Conrad advised the Court that there was no reason for an evidentiary hearing because, in her view “[Defendants are] fricken crooks and they should be in jail and you know that.” (12/20 Tr. 17.) She went on to opine: “come on, this is anything in favor of the defendants.... And they brought the motion against the prosecution.... It’s ridiculous.” (12/20 Tr. 17.) Daugerdas, 867 F.Supp.2d at 455-56. .On February 15, 2012, Conrad refused to present herself at the evidentiary hearing. She attended only after the court issued a warrant for her immediate arrest, and the U.S. Marshals took her into custody and brought her to court. See id. at 475. At the February hearing (“Hearing” or “Hr’g”), Conrad invoked her Fifth Amendment privilege against self-incrimi-n’ation but, on motion of the government, was granted use immunity. See id. at 456 n. 2 (immunity from use of her “testimony or other information compelled under this Order, or any information directly or indirectly derived from such testimony or other information, ... except a prosecution for perjury, giving a false statement, or otherwise failing to comply with this Order.” (internal quotation marks omitted)). At the Hearing, Conrad admitted that she lied to the Court to make herself more “marketable” as a juror.... She also testified that she believed that if the truth were known, “the defense counsel would be wild to have me” on the jury.... Conrad reasoned that Defendants would want “crooks” on the jury because they themselves were “crooks.” .... Indeed, Conrad admitted that she had used this to rationalize her conduct to herself at the time of voir dire. (Hr’g Tr. 229 (“Q. You told yourself at the time that it was OK from the defendants’ perspective because, if anything, somebody who was married to a criminal would tend to favor other criminals, right? A. I guess it can be characterized as that.”).) Conrad acknowledged that she made the conscious decision to perjure herself between the first and second day of voir dire. After hearing the questions posed to the first two prospective jurors, she conjured up a personal profile that she thought would be attractive .... At the Hearing, Conrad opined that “most attorneys” are “career criminals.” .... Daugerdas and Guerin are attorneys, and while Parse is [sic] licensed to practice law, he is an investment banker. She twice underlined the difference in financial success between herself and Daugerdas. When asked if she had about $14,000 in assets, Conrad retorted: “Correct. Much less than your client.”.... When asked whether she was financially successful as a lawyer, Conrad testified: “I don’t live an extravagant lifestyle like Mr. Daugerdas.” Daugerdas, 867 F.Supp.2d at 456 (footnote omitted) (emphases and brackets ours). When given a chance to explain her declaration that all the Defendants were “crooks” and that their motion for a new trial was “ridiculous,” she claimed repeatedly that she did not recall what she meant to convey. She also claimed she did not know why she made those statements because “I’m not a psychologist.” Id. Her responses to other inquiries into her past statements were similarly evasive. See id. at 456-57; id. at 457 (“She claimed repeatedly that she could neither understand the questions nor remember the facts.”) The court concluded that Conrad was “a pathological liar and utterly untrustworthy.” Id. at 470. Conrad’s lies are breathtaking. In response to direct and unambiguous questions, she intentionally provided numerous false and misleading answers and omitted material information. Conrad’s lies were calculated to prevent the Court and the parties from learning her true identity, which would have prevented her from serving on the jury. This is not a case where the relevant voir dire questions were somehow vague or ambiguous, particularly given Conrad’s status as an attorney.... The Court’s questions to Conrad were clear, simple, and direct. The events she lied about were recent, personally significant, and directly affected her qualifications to serve as a juror. Her arrests and suspensions from the practice of law were not the result of youthful indiscretions or errors on the part of police or courts.... There is no dispute that Conrad was aware of her prior convictions, her attorney disciplinary problems, and her personal injury suit at the time she answered the Court’s questions under oath. There is also no question that she made a conscious decision to hide them from the Court. Id. at 468-69 (emphases added). Conrad testified that she knew she could have made nonpublic disclosures to the court and the attorneys at a sidebar; but she said “ T know my disclosures definitely would not have allowed me to sit as a juror.’ ” Id. at 469 (quoting Hr’g Tr. 237). The court concluded that Conrad’s answers concealing material facts were attributable neither to a desire to avoid embarrassment nor to honest mistakes: They were deliberate and intentional lies. Conrad confessed that she purposefully lied and omitted material information in her voir dire testimony to make herself more “marketable” as a juror. She yearned for professional redemption or some psychic satisfaction: “And having been suspended for so long, I guess mentally I would think maybe I’m back in the swing of things now.” (Hr’g Tr. 236.) It is evident that Conrad’s untruthful responses to the Court’s voir dire questions were premeditated and deliberate. There is no innocent explanation. Daugerdas, 867 F.Supp.2d at 469. The court found “that Conrad was actually biased against Defendants.” Id. at 471. It also observed that Conrad’s May Letter to Okula buttresses the conclusion that she was actually biased. Written the day after the trial concluded, the May Letter indicates that Conrad identified with the Government. She expressed that bias in her emphasis on “Our Government”— a phrase she could not explain. (Hr’g Tr. at 202.) Her bias also bled through when she wrote that she “did fight the good fight” against acquitting Parse on any counts but eventually had to “throw in the towel.” Her choice of words shows that Conrad saw herself not as a fact-finder, but as a partisan for “Our Government.” -In addition, Conrad included her cell phone number in the return address of the May Letter, and she testified that'she was “very anxious” to talk to the prosecutors after the verdict. (Hr’g Tr. at 194.) By contrast, she testified that there was “no reason” for her to talk to the defense lawyers. (Hr’g Tr. at 196.) Daugerdas, 867 F.Supp.2d at 471 (emphases ours). The court discredited Conrad’s self-serving claims that she was unbiased, crediting instead her overtly biased statements: Conrad’s own statements and demeanor belie her claim of impartiality. Her animus toward lawyers — like Defendants here — was evident not only in her comment that most attorneys are criminals but also in her attitude at the evidentia-ry hearing. Her comment that all attorneys are “crooks” was a direct statement of bias against the Defendants. Conrad’s statement can only be understood as reflecting a pre-existing bias against lawyers. Id. (emphases ours). B. Defendants’ Knowledge or Suspicions as to Conrad’s Misconduct The memorandum of law in support of defendants’ new-trial motion, which had been drafted largely by Parse’s attorneys, see Daugerdas, 867 F.Supp.2d at 458 n. 3, suggested that defendants had had no inkling of any misconduct by Conrad prior to her posttrial letter to the government. The district court noted that the memorandum stated that “[t]he' tone and content of [Conrad’s May Letter], which were in sharp contrast to the image Conrad had projected through the trial (‘always head down, taking notes!’), caused defendants concern and prompted them to investigate.” (Memorandum of Law in Support of Defendants’ Motion for a New Trial, dated July 8, 2011 (“Def. Br.”) at 9 (emphasis added) (quoting the May Letter).) Defendants also stated they learned of, inter alia, Conrad’s status as a suspended lawyer and the pending disciplinary proceedings against her by “conducting public records searches in the wake of Conrad’s May 25, 2011 post-verdict letter to the government^] ” (Def. Br. at 3 (emphasis added).) They further stated that “Conrad’s voir dire responses did not provide even a hint of bias and she exhibited no outward signs of any mental or emotional instability!.]” (Def. Br. at 8.) And they represented that they “had no basis to inquire whether Conrad was lying in response to each of the Court’s questions [during voir dire].” (Def. Br. at 32 n. 13.) Daugerdas, 867 F.Supp.2d at 458. The court found that, absent any other information, “the clear implication of these statements was that they had no idea of Conrad’s true identity and background until their post-verdict investigation following the receipt of Conrad’s May Letter.” Id. The court sought additional information in a July 15, 2011 conference call with the parties. In that call, the 'government said it had been unaware of any of the facts set out in defendants’ motion, and it questioned whether defendants’ rights to challenge Conrad had been waived. The court asked whether any of the defendants had previously been aware of the facts set out in the new-trial motion. The attorneys for Daugerdas, Guerin, and Field promptly responded that they had had no prior knowledge of any of the facts that had' come to light about Conrad’s nondisclosures and misrepresentations. See id. at 459. The responses of Parse’s counsel were far less unequivocal and prompted the court to request further information from that firm: Parse’s counsel, Theresa Trzaskoma (“Trzaskoma”), responded, “Your Honor, we were not aware of the facts that have come to light and I think that if your Honor deems it appropriate, we can submit a letter.”.... This Court invited a submission from Parse’s counsel to make certain that no jury consultant had any information about Conrad before the verdict.... The colloquy concluded with a seemingly innocuous feint by Parse’s counsel: “The only thing additional that I would offer, your Honor, is — well, we can address this in the letter. I think it’s more appropriate.” Id. Thereafter, Theresa Trzaskoma, Susan Bruñe, and Laurie Edelstein, partners in Bruñe & Richard LLP (or “B & R”), Parse’s trial attorneys, “began to disclose in stages the full extent of their investigation into Conrad’s background.” Id. On July 21, Bruñe submitted a letter revealing for the first time that prior to voir dire, Bruñe & Richard had conducted a Google search of the terms “Catherine Conrad” and “New York” and discovered the 2010 Suspension Order, suspending a Catherine M. Conrad from the practice of law. (Bruñe & Richard Letter dated July 21, 2011 (“July 21 Letter”)....) But because Conrad stated during voir dire that her highest level of education was a B.A. in English Literature, the Bruñe & Richard trial team concluded that Conrad could not be the suspended lawyer. (July 21 Letter, at 2.) Despite the exact match of Conrad’s name with the middle initial “M.” on both the jury roll and the 2010 Suspension Order, Bruñe & Richard ruled out the possibility that Conrad lied during voir dire, and they did not raise their discovery of the 2010 Suspension Order with the Court. (July 21 Letter, at 2.) Daugerdas, 867 F.Supp.2d at 460 (emphases ours). In the July 21 Letter, Bruñe & Richard also disclosed for the first time that they had conducted additional research about Conrad following her submission of a note to the Court on May 11, 2011 (the “Juror Note”), in the midst of closing arguments. (July 21 Letter, at 2.) The Court shared the contents of the Juror Note with counsel at the end of the day after closing arguments concluded. (Trial Tr. 8832.) In the Juror Note, Conrad asked whether the Court would instruct the jury on the legal doctrine of respondeat superior and posed a question about vicarious liability. (Trial Tr. 8832.) No party had raised either term during trial, and neither term was germane to the questions at issue. The Juror Note prompted Trzaskoma to direct a paralegal to conduct further research on Conrad early the next morning. The paralegal conducted a Google search and located the 2007 and 2010 Suspension Orders, which suspended “Catherine M. Conrad” from the practice of law in New York. (July 21 Letter, at 2.) The paralegal also searched Westlaw for information on “Catherine M. Conrad,” generated a report (the “Westlaw Report”), and provided it to Trzaskoma. (July 21 Letter, at 2; Ex. 1.) The Westlaw Report — in Bruñe & Richard’s hands just after the start of jury deliberations — was freighted with information revealing Juror No. l’s hidden identity. The Westlaw Report lists a previous address for Catherine M. Conrad in Bronxville — the same exact name and town listed for Conrad on the jury roll — and also shows that Conrad was a suspended attorney with a Bronx address. It lists Robert J. Conrad as a member of Conrad’s household and indicates that Conrad was involved in a civil lawsuit in Bronx Supreme Court. The Westlaw Report links the Bronx civil suit to Conrad— the suspended attorney — with a “Confidence Level” of 99%. Daugerdas, 867 F.Supp.2d at 460-61 (footnote omitted) (emphases ours). According to the July 21 Letter, after receiving the Westlaw Report, “Trzasko-ma had the initial thought that the lawyer and the juror were potentially one and the same, but she reviewed the report and found it confusing, internally inconsistent and not reliable.” (July 21 Letter, at 2.) Trzaskoma then conferred with Bruñe and Edelstein. They believed Conrad’s use of legal terms in the Juror Note was consistent with her involvement in a personal injury action and thought that it was “inconceivable” that Conrad lied during voir dire. Thus, they concluded collectively that she could not be the suspended attorney. (July 21 Letter, at 2-3.) After reaching that conclusion, they did not bring any of the underlying information to the attention of the Court or the Government. Nor did they revisit the question between May 12 and May 21*, when the jury returned its verdict. After receiving Conrad’s post-verdict May Letter, Parse’s attorneys conducted another Google search of Conrad and once again located the 2010 Suspension Order. (July 21 Letter, at 3.) This time, they matched a telephone number Conrad provided in the May Letter with a telephone number associated with Conrad on the New York State Unified Court System’s attorney registration website. (July 21 Letter, at 3.) At this point, Parse’s trial team purportedly realized, for the first time, that it was no longer “inconceivable” that Conrad was not who she claimed to be during voir dire. (July 21 Letter, at 3.) Bruñe & Richard then conducted a two-week investigation, which unearthed Conrad’s personal injury lawsuit filings, her property records, her criminal records, her husband’s criminal records, and their marriage records. (July 21 Letter, at 3-4.) Only then did they apparently conclude that they had the metaphysical certainty necessary to alert this Court to Conrad’s juror misconduct and to seek a new trial for Parse. (July 21 Letter, at 3-4.). Daugerdas, 867 F.Supp.2d at 461 (emphases ours). Upon receiving the July 21 Letter, this Court scheduled another conference call with the parties and counsel. During that call, this Court questioned Bruñe about the discrepancies between the version of events provided in the motion papers and the July 21 Letter. 0See July 22, 2011 Transcript (“7/22 Tr.”) 5.) Bruñe endeavored to explain: Your Honor, when we submitted the brief that we did we were submitting with the other three lawyers and as demonstrated by the statements that three of the firms made on the phone on the Friday [July 15th] conference, their level of knowledge is apparently non-existent and our situation is different and it is for that reason that Ms. Trzaskoma proposed to file the letter which we did as opposed to just responding on the call. We did not know that this juror was essentially posing as a different person at no point during the trial. We certainly anticipated that the government was going to raise the issue of waiver, it features prominently in the Supreme Court case that controls here, and we anticipated that when he inquired, which he inevitably was going to do, we were going to lay out the facts accurately as we have. And my sense of what we are trying to accomplish — but of course your Honor will guide me on this — is that Mr. Okula needed the facts so that he can make whatever waiver argument he proposes to make in his brief. And it is with that in mind, and I of course also responded to the Court, that I laid this out. But, I certainly didn’t mean to suggest by our opening brief that we had no information about Ms. Conrad. We had the information that I’ve laid out but at no point did we know that she was perpetrating a fraud on this Court and unfortunately harming Mr. Parse in the way that she did. (7/22 Tr. 5-6.) Daugerdas, 867 F.Supp.2d at 461-62. The district court stated that at the February 2012 Hearing, Parse’s attorneys acknowledged candidly that had the Court or the Government not inquired, Bruñe & Richard would never have disclosed any of their investigation into Conrad. (Hr’g Tr. 79 (“[HERNANDEZ:] Ms. Trzaskoma, if the government had not inquired about your firm’s knowledge about certain facts that you had about Catherine Conrad, were you ever going to disclose that information to the Court? [TRZASKOMA:] I don’t know I can answer that.... It didn’t occur to me to disclose it. As I said, I regret that. But I can’t say that it wouldn’t have come up subsequently.”); Hr’g Tr. 817 (“COURT: Ms. Bruñe, ... would your firm have disclosed the information in your firm’s July 21 letter and the investigation into Juror No. 1 if the Court had not inquired or the government failed to raise the waiver issue? [BRUÑE]: I don’t think we would have your Honor[.]”); Hr’g Tr. at 357 (“OKU-LA: [A]re you saying that you would have felt comfortable that you had fulfilled all your obligations if the Court had decided this motion without learning of the facts concerning what your firm knew prior to receiving the [May Letter]? Yes or no. [EDELSTEIN]: Yes.”).) Daugerdas, 867 F.Supp.2d at 459-60. In addition to the testimony from Parse’s attorneys at the February 2012 hearing, the district court had before it a series of internal firm emails produced by Bruñe & Richard pursuant to an August 2011 order granting a motion by the government for discovery of documents relating to the firm’s prior investigations of Conrad. Emails discussing information gathered by a jury consultant firm (“Nar-dello”) reflected the B & R grading system for prospective jurors, in which a “D” signified somewhat unlikely to be pro-defense and a “Z” meant that no meaningful information was available. The district court noted that the following emails were exchanged among B & R personnel on May 12, 2011, i.e., the day on which jury deliberations began, which was the day after the parties were informed of Conrad’s inquiry to the court about respondeat superior and vicarious liability: 7:25 a.m.: Trzaskoma requests that her team “send [her] all of our intelligence on juror # 1, including pre-voir dire info we thought we had.” 7:54 a.m.: Paralegal David Benhamou e-mails Trzaskoma a summary of Conrad’s answers during voir dire. 8:02 a.m.: Vivian Stapp, an associate at Bruñe & Richard, responds to Ben-hamou’s email regarding the lack of information in their files. She observes: “We don’t have Nardello info gathered for her. She was initially given a ‘Z’ grade and then it looks like we gave a ‘D’ at some point, probably because we thought she was that lawyer. Unfortunately we don’t have anything else for her. I’ll keep looking but that’s what the spreadsheet is showing. A little more: ‘is a plaintiff in a pending personal injury case in South Bronx Division.’ ” 10:55 a.m.: Trzaskoma advises Ben-hamou, “What we found before voir dire was that maybe she was a suspended lawyer.” 11:06 a.m.: Randall Kim, an associate at Bruñe & Richard, replies to Stapp: ‘We (I thought TT [Trzaskoma]) found something more, which more clearly suggested she has been/is and [sic] alcoholic.” 11:07 a.m.: Benhamou sends Kim, Stapp, and Trzaskoma the link to the 2010 Suspension Order. 11:13 a.m.: Stapp then observes to Kim, We have Conrad down as a ‘Do Not Search.’ I don’t think she’s that lawyer, unless she blatantly omitted information during voir dire when describing her educational background (or was able to become a lawyer without going to law school.)” 11:15 a.m.: Benhamou, - at Trzasko-ma’s request, sends Trzaskoma, Kim, and Stapp an excerpt of Conrad’s voir dire testimony. 11:17 a.m.: After reviewing Conrad’s voir dire testimony, Trzaskoma instructs Benhamou, Kim, and Stapp to keep a dossier on Conrad, by noting: “Ok, unless Conrad totally lied about her highest level of education, it can’t be the samé person as the suspended lawyer. But let’s keep a little dossier on her.” 11:22 a.m.: Benhamou asks Trzasko-ma if she wants him to “do a people search on Westlaw,” .and she responds less than one minute later, “Sure.” 2:24 p.m.: Benhamou sends Trzasko-ma the Westlaw Report with the following message: “Attachéd is a Westlaw report. I picked the Catherine M. Conrad who has an address in Bronxville, which seemed to match her testimony. Westlaw thinks this is the same suspended lawyer from the Bronx, but perhaps it’s confusing two people or I picked the wrong one. If you really care about this, I suggest you have Nar-dello run this down as I’m not too sure what I’m doing here.” Benhamou then went on to describe some of the information in the Westlaw Report, including the reference to a “Robert J. Conrad.” 2:32 p.m.: Trzaskoma responds to Benhamou: “I think Robert Conrad is ■ her father — he is an immigration judge.” 2:36 p.m.: Trzaskoma shares with Benhamou: “Jesus, I do think that it’s her. Can you please track down that lawsuit?” (Emphasis added). Daugerdas, 867 F.Supp.2d at 463-64 (footnotes omitted). The district court concluded: Any fair reading of these e-mail exchanges shows that Parse’s attorneys had actionable intelligence that Conrad was an imposter. That knowledge demanded swift action to bring the matter to the Court’s attention. Further investigation would have been easy and prudent. But Parse’s attorneys chose to do neither. In her September 15 affidavit, Bruñe asserts that sometime after 2:36 p.m., Trzaskoma shared with her and Edel-stein the possibility that the suspended lawyer and Juror No. 1 were the same person. (Bruñe Aff. ¶ 12.) While now armed with the Westlaw Report, Bruñe, Trzaskoma, and Edelstein nevertheless adhered to their earlier conclusion during voir dire, namely that “Ms. Conrad could be a suspended lawyer only if she had lied repeatedly during voir dire, and it .seemed inconceivable that any juror, much less a lawyer, would perjure herself so brazenly.” (Bruñe ' Aff. ¶ 12.) Through that rationalization, Parse’s attorneys convinced themselves that “no additional research was warranted, and none was conducted.” (Bruñe Aff. ¶ 12.) Missing from the Bruñe Affidavit are any particulars about Parse’s attorneys’ thought processes in the wake of the newly acquired Westlaw Report, Ben-hamou’s professed uncertainty with his research and, most importantly, Trzas-koma’s epiphany just hours earlier that Juror No. 1 was the suspended attorney with alcohol issues (“Jesus, I do think that it’s her”). Moreover, Brune’s Affidavit provides no details about whether Parse’s attorneys discussed alerting the Court to their investigation, nor does it explain why they did not ask the Nardel-lo firm to investigate Juror No. 1 immediately. Daugerdas, 867 F.Supp.2d at 464-65. The district court noted that thereafter, at the February 2012 Hearing, Bruñe & Richard offered another layer of detail about the events of May 12. Trzaskoma acknowledged reviewing the Westlaw Report after Benhamou sent it to her that morning. (See Hr’g Tr. 49-50 (“It struck me that holy cow, it’s possible that it’s the same person, and I was looking at the Westlaw report to try to figure out is there some way that this tells me one way or the other, that gives me more information.”).) But she testified that she did not look at the Westlaw Report until after sending the “Jesus” email and she minimized its significance on her thought process. (Hr’g Tr. 55-56.) Citing her inexperience in reading such reports, Trzaskoma claimed that she questioned the Westlaw Report’s accuracy and whether it had aggregated information about multiple Catherine Conrads. (Hr’g Tr. 49-55.) Trzaskoma offered no explanation for her failure to seek assistance from her colleagues. She also quibbled over whether Juror No. 1 physically appeared to be a woman in her early forties (maintaining that she believed Juror No. 1 to be “close to 50”). And even though she was looking for correlations to Juror No. 1, she “did not focus on the [middle initial] ‘M’ ” and she “didn’t think of it” as a way to help her narrow down the information in the Westlaw Report. (Hr’g Tr. 24, 50). Daugerdas, 867 F.Supp.2d at 465. The court noted that Trzaskoma said she and her partners met briefly on May 12 in Foley Square Plaza, just outside the courthouse but did not discuss the new information: Notwithstanding her Eureka e-mail a few hours earlier — “Jesus, I do think that it’s her” — Trzaskoma claimed that when she met with her partners, she did not think that Conrad and the suspended attorney were the same person, but raised only the “possibility” that there might be a connection. (Hr’g Tr. 58, 92, 280.) Trzaskoma never shared the existence of the Westlaw Report or its contents with Bruñe or Edelstein. Indeed, all three Bruñe & Richard partners testified in unison that they never mentioned, let alone discussed, the Westlaw Report in their Foley Square conversation. (Hr’g Tr. at 58-59, 281, 328.) Bruñe made the point emphatically: “I’m confident that [Trzaskoma made no mention whatsoever of the Westlaw Report], and here is why. Laurie Edel-stein .is the kind of person who will always kind of say, well, show me the case, show me the document. She is extremely thorough and if [Trzaskoma] had referenced the document in the conversation, that’s what Ms. Edelstein would have said. So I know that there was no reference to [the Westlaw Report] in the conversation.” (Hr’g Tr. 281.) In exploring the basis for Trzas-koma’s rekindled belief that Conrad could be the suspended attorney, Parse’s attorneys only considered the Juror Note and the transcript of Conrad’s voir dire testimony. (Hr’g Tr. 58-59, 281, 328.) Further, according to Brune’s and Edelstein’s testimony, Trzaskoma never mentioned the Westlaw Report or the May 12 internal e-mails about Bruñe & Richard’s research of Conrad at any point during the eleven days of jury deliberations. (Hr’g Tr. 59, 281.) Daugerdas, 867 F.Supp.2d at 465-66. C. The Granting of a New Trial to Dau-gerdas, Guerin, and Field The district court, discussing the relevant Supreme Court eases, including McDonough Power Equipment, Inc. v. Greenwood, 464 U.S. 548, 104 S.Ct. 845, 78 L.Ed.2d 663 (1984) (“McDonough”), and courts of appeals cases, noted that the Sixth Amendment guarantees an accused the right to a trial by an impartial jury. “An impartial jury is one in which every juror is ‘capable and willing to decide the case solely on the evidence before [her].’ ” Daugerdas, 867 F.Supp.2d at 470 (quoting McDonough, 464 U.S. at 554, 104 S.Ct. 845). “Voir dire plays an essential role in protecting the right to a trial by an impartial jury,” and as questioning on voir dire seeks to ferret out actual or potential biases on the part of potential jurors, a “juror’s dishonesty during voir dire undermines a defendant’s right to a fair trial.” Daugerdas, 867 F.Supp.2d at 468. “If the answers to the questions [during voir dire] are willfully evasive or knowingly untrue, the talesman, when accepted, is a juror in name only.... His relation to the court and to the parties is tainted in its origin; it is a mere pretense and sham.” Clark v. United States, 289 U.S. 1, 11, 53 S.Ct. 465, 77 L.Ed. 993 (1933); see also McDonough, 464 U.S. at 554, 104 S.Ct. 845 (“The necessity of truthful answers by prospective jurors if [voir dire] is to serve its purpose is obvious.”). Thus, a juror who lies her way onto a jury is not really a juror at all; she is an interloper akin “to a stranger who sneaks into the jury room.” Dyer v. Calderon, 151 F.3d 970, 983 (9th Cir.1998) (en banc). “Justice must satisfy the appearance of justice.” Offutt v. United States, 348 U.S. 11, 14, 75 S.Ct. 11, 99 L.Ed. 11 (1954). Daugerdas, 867 F.Supp.2d at 468; see also id. (“where a juror deliberately conceals information that, if revealed, ‘might thwart her desire to sit’ on the jury, any resulting conviction ‘cannot stand’ because such conduct ‘obstructs] the voir dire and indicate[s] an impermissible partiality on the juror’s part’” (quoting United States v. Colombo, 869 F.2d 149, 151 (2d Cir.1989) (“Colombo”))). The district court noted that a potential juror should be discharged when there is actual bias, implied bias, or inferable bias. In this case, it found all three bias categories applicable to bar Conrad from serving on the jury. “Whether a juror is actually biased is a question of fact,” Daugerdas, 867 F.Supp.2d at 470; and, as described in Part I.A.3. above, the court found that Conrad was in fact biased against' these defendants, see id. at 471. “Implied bias,” in contrast, is determined as a matter of law and attributed to a prospective juror regardless of actual partiality.... Courts imply bias in extreme situations where the relationship between a prospective juror and some aspect of the litigation is such- that it is highly unlikely that the average person could remain impartial in his deliberations under the circumstances.... Significantly, courts imply bias where repeated lies in voir dire imply that the juror concealed material facts in order to secure a spot on the particular jury.... A juror ... who lies materially and repeatedly in response to legitimate inquiries about her background introduces destructive uncertainties into the process. Daugerdas, 867 F.Supp.2d at 472 (internal quotation marks omitted) (emphases ours). “The nature, scope and extent of the lies a juror tells may, in and of themselves, demonstrate- an undue partiality or bias.... Therefore, dishonest answers are a factor that can contribute to a finding of implied bias.” Id. at 473. “Where a juror is impliedly biased, disqualification of that juror is mandatory.” . Id. at 472. The court concluded: The principle of implied bias applies with particular force here. Not only did Conrad lie, she created a totally fictitious persona in her drive to get on the jury. Few, if any, prospective jurors would willfully violate their oath, and knowingly subject themselves to prosecution for perjury, without a strong personal interest in the outcome of the case. See Colombo, 869 F.2d at 151. Conrad did not tell a discrete lie or two. Rather, she presented herself as an entirely different person and lied about virtually every detail of her life.... And as a lawyer, she had to appreciate the consequences of lying under oath.... Anyone so anxious to serve on a jury that she would misrepresent who she is, and risk criminal prosecution by doing so, see 18 U.S.C. § 1621, cannot be considered impartial. Someone who commits fraud to get on a jury cannot evaluate the credibility of witnesses, much less sit in judgment of others who are accused of fraud. Daugerdas, 867 F.Supp.2d at 473 (emphases added). The court concluded: The brazenness of Conrad’s deliberate lies and her demonstrated inability to distinguish truth from falsehood added destructive uncertainty to the fact-finding process.... Accordingly, this Court concludes that Conrad was impliedly biased. Id. at 474 (internal quotation marks omitted). Finally, the court noted that a juror may be discharged when bias is “ ‘inferred’ ”: “ ‘Inferable’ or ‘inferred’ bias exists “ ‘when a juror discloses a fact that bespeaks a risk of partiality sufficiently significant to warrant granting the trial judge discretion to excuse the juror for cause, but not so great as to make mandatory a presumption of bias.’ ” Id. (quoting United States v. Greer, 285 F.3d 158, 171 (2d Cir.2002) (“Greer ”) (quoting United States v. Torres, 128 F.3d 38, 47 (2d Cir.1997) (“Torres ”), cert. denied, 523 U.S. 1065, 118 S.Ct. 1399, 140 L.Ed.2d 657 (1998))). And “ ‘once facts are elicited that permit a finding of inferable bias, then, just as in the situation of implied bias, the juror’s statements as to his or her ability to be impartial become irrelevant.’ ” Daugerdas, 867 F.Supp.2d at 474 (quoting Torres, 128 F.3d at 47); see also Greer, 285 F.3d at 171. Here, the court concluded: Had this Court known the facts, Conrad would have been subject to a valid challenge for cause. She was manifestly incapable of performing the central functions of a juror — evaluating witness credibility and making a fair assessment of the evidence. Solely on the basis of her false voir dire testimony, the Court could easily infer that she is inherently unable to perform the crucial function of ascertaining the truth. The fact is, however, that there is a mountain of other evidence showing that not only did she lie to this Court on voir dire, but that she is a pathological liar who does not know the difference between truth and lie. The presence of such a tainted juror, who cannot appreciate the meaning of an oath is simply intolerable. Daugerdas, 867 F.Supp.2d at 475 (emphasis added). Conrad’s actions in this case, as well as in other lawsuits in which she has participated, “evinces a shocking disregard for the judicial system[.]” 2007 Suspension Order, 48 A.D.3d at 188, 846 N.Y.S.2d 912. In addition to her serial perjury, Conrad’s direct defiance of the Court and its orders, as well as her statements at the December 20 and February 15 hearings, betray a fundamental contempt for the judicial process. She advised the Court at the December 20 hearing that there was no point in holding a hearing because the Defendants are “fricken crooks and they should be in jail.” (12/20 Tr. at 17.) Daugerdas, 867 F.Supp.2d at 475; see also id. at 475-76 (recounting Conrad’s contumacious and bizarre behavior throughout the posttrial proceedings). The court concluded: Such a person has no business sitting on a jury in judgment of others. Accordingly, had this Court known the full extent of Conrad’s character at voir dire, it would have exercised its discretion and inferred that she was biased. Id. at 476. It noted that, although the Second Circuit had never found reason to overturn a verdict on the basis of juror nondisclosure under McDonough, here “the exceptional circumstances — deliberate lies engineered to create a fictitious, ‘marketable’ juror — presented by this case warrant such extraordinary relief.” Dau-gerdas, 867 F.Supp.2d at 468. Having seen no reason to believe that Daugerdas, Guerin, Field, or their respective attorneys had knowledge or suspicions as to Conrad’s misconduct prior to the end of the trial, see id. at 459, 462 n. 6, the court concluded that Daugerdas, Guerin, and Field were entitled to a new trial. D. The Denial of a New Trial for Parse In contrast, the district court concluded that Parse had waived his right to a new trial. Despite the argument that Parse himself had had no knowledge of Conrad’s falsehoods, the court stated that it “bears noting at the outset that a defendant can waive certain rights through the actions of his attorneys, even if the defendant himself was unaware of the circumstances and actions giving rise to the waiver.” Dau-gerdas, 867 F.Supp.2d at 476. The court concluded that “Parse ... is bound by Bruñe & Richard’s actions and decisions at trial,” id. at 477, stating that a defendant waives his right to an impartial jury if defense counsel were aware of the evidence giving rise to the motion for a new trial or failed to exercise reasonable diligence in discovering that evidence. To be sure, actual knowledge of facts disqualifying a juror is an absolute bar to any challenge to that juror after a verdict. McDonough, 464 U.S. at 551 n. 2, 104 S.Ct. 845 (party who had knowledge “would be barred from later challenging the composition of the jury when they had chosen not to interrogate [the suspected juror] further upon receiving an answer which they thought to be factually incorrect”), Daugerdas, 867 F.Supp.2d at 479 (emphases ours). The district court noted that the McDonough Court, in making the above-quoted statement, had cited Johnson v. Hill, 274 F.2d 110, 115-16 (8th Cir.1960) (“Johnson”), in which the Eighth Circuit had stated as follows: The right to challenge the panel or to challenge a particular juror may be waived, and in fact is waived by failure to seasonably object.... It is established that failure to object at the time the jury is empaneled operates as a conclusive waiver if the basis of the objection is known or might have been known or discovered through the exercise of reasonable diligence, or if the party is otherwise chargeable with knowledge of the ground of the objection. 274 F.2d at 116 (internal quotation marks omitted) (emphasis ours). The district court stated: As Johnson and subsequent cases make clear, litigants and their counsel must act with reasonable diligence based on information about juror misconduct in their possession, or they will be deemed to have waived their right to an impartial jury based on the challenged juror misconduct. Daugerdas, 867 F.Supp.2d at 480; see also id. at 476-80 (discussing additional cases from other circuits). In the present case, the district court found that Parse’s attorneys knew that Conrad was a suspended attorney — or at least they would have known had they exercised due diligence: Bruñe, Edelstein, and Trzaskoma all testified that, after Trzaskoma raised her concern about Conrad during their Foley Square conversation, they discussed Conrad’s voir dire answers, and observed that Conrad’s odd note about vicarious liability and respondeat superior could be explained as relating to her personal injury lawsuit, which Conrad had mentioned during voir dire. (Hr’g Tr. 38, 60, 280.) On that slender reed, they unilaterally decided that no further investigation was necessary— even though Trzaskoma recalled mentioning that they should have an investigator look at the issue: “what I thought at the time was that we would need to investigate.” (Hr’g Tr. 60, 92.) Trzas-koma asked Bruñe whether they should keep looking at the issue, and Bruñe told her “no, just leave it.” (Hr’g Tr. 60, 283.) According to Bruñe, she shut down further inquiry because she credited Conrad’s voir dire responses. But she also acknowledged that Parse’s trial team had not taken any additional steps to rule out that Conrad was the suspended lawyer. (Hr’g Tr. 282.) This Court cannot fathom how lawyers as thorough as Bruñe, Edelstein, and Trzaskoma would neglect to tie off such a glaring loose end. Acting on Brune’s instruction to “leave it,” Trzaskoma directed Benham-ou to “stand down” on his efforts to obtain records of the civil lawsuit referenced in the Westlaw Report. (Hr’g Tr. 93.) Edelstein added that she, Bruñe, and Trzaskoma specifically discussed whether they should bring the issue to the Court’s attention, and decided against it because she thought it was “inconceivable” that Conrad had lied. (Hr’g Tr. 354-55.) This was another tragic misjudgment. Paul Schoeman, Brubaker’s counsel, testified that some time after the receipt of the Juror Note on May 11, and likely the Monday thereafter, Trzaskoma told him that there was a suspended attorney named Catherine Conrad, but that Parse’s attorneys had concluded that Juror No. 1 was not that person. (Hr’g Tr. 362-65.) Trzaskoma did not mention the Westlaw Report or other information Bruñe & Richard unearthed. Barry Berke, another attorney for Bru-baker, testified to a similar conversation with Bruñe. (Hr’g Tr. 368-69.) In sum, prior to the start of voir dire, Parse’s attorneys knew that (1) Juror No. 1 lived in Bronxville, was a plaintiff in a pending personal injury lawsuit, and had a father who was an immigration officer; and (2) a woman with the identical name of “Catherine M. Conrad” was a suspended New York attorney with an alcohol dependency. Before jury deliberations began, Parse’s attorneys knew that (1) Juror No
