MEMORANDUM AND ORDER
YOUNG, District Judge.
I. INTRODUCTION
Habeas Petitioner Dewayne Hampton (“Hampton”) seeks post-conviction relief based on the now infamous scandal involving state lab chemist Annie Dookhan (“Dookhan”). Mot. Vacate, Set Aside, or Correct Sentence Person Federal Custody, Ex. 1, Mot. Vac. Plea Alternative, Vacate Sentence, Pursuant 28 U.S.C. § 2255 (“Def. Br.”), ECF No. 91-1. This case presents an issue of first impression in the growing line of cases resulting from the Dookhan scandal. Hampton does not seek to vacate his guilty plea but instead argues that his Due Process rights were violated because the mandatory minimum sentence imposed on him was based on a quantity of drugs tested and weighed by Dookhan. The Court holds that on this unusual (and thus far, unique) set of facts, Hampton is entitled to relief in the form of resentencing.
A. Factual Background
1. Hampton’s Arrest and Testing of Substances
Hampton — along with co-defendants Willie Brown (“Brown”) and Ashley Clark (“Clark”) — was a member of a drug distribution conspiracy. Opp’n. Dewayne Hampton’s Mot. Vacate (“Govt. Br.”) 3, ECF No. 93. Between October 2008 and August 2009, a cooperating witness, at the direction of law enforcement agents, allegedly purchased 350 grams of crack cocaine from the three defendants during twenty-one controlled sales. Id. The government [433]*433avers that Hampton participated directly in twenty of the twenty-one transactions, each of which involved a sale of either a half ounce or a full ounce of crack cocaine. Id. An additional fifty grams of crack cocaine were seized from Hampton’s residence during his arrest. Id. at 1.
Of the twenty controlled purchases attributable to Hampton, on at least one occasion law enforcement agents field tested the substances collected, which yielded a positive result for cocaine. Id. at 4. The substances recovered from eighteen of the purchases were tested at the Hinton State Laboratory in Jamaica Plain where Dookhan worked (the “state lab”). See id. Of those eighteen samples, Dookhan was the primary or secondary chemist for fourteen samples.1 Id. at 4-5. Two samples were tested by a Drug Enforcement Agency lab. Id. at 4. All tests returned positive results for cocaine. Id.
2. Annie Dookhan
Dookhan worked as a chemist at the state lab from 2003 until 2012. See Def. Br. 7, 11. In June 2011, Dookhan’s supervisors discovered she had taken evidence from a safe without authorization, removed ninety drug samples from the office, and forged a co-worker’s initials on the evidence log. Supplemental Mem., Ex. A, Investigation Drug Lab. William A. Hinton State Lab. Inst. 2002-2012 (“OIG Report”) 63, 65, EOF No. 113-1. The Department of Public Health (“DPH”) Director of Laboratory Services reported the incident by letter to the Norfolk District Attorney in February 2012. Id. at 72. Dookhan went on administrative leave in February 2012 and resigned on March 9, 2012. Id. at 73. After further investigation, the lab closed. Id. at 20.
Dookhan was charged in the Massachusetts Superior Court with twenty-nine crimes, including perjury, obstruction of justice, tampering with evidence, and falsely claiming to hold a degree. Def. Br. 5. In November 2013, Dookhan pled guilty to twenty-seven counts and subsequently was sentenced to three to five years in prison, followed by two years of probation. OIG Report 11. Discovery in the case against Dookhan revealed that she breached lab protocol by, among other things:
• Dry-labbing (certifying, without testing, that a substance was the suspected drug);
• Placing samples from different cases together on her bench;
• “Batching” samples together and testing some but not others;
• Intentionally contaminating a sample by using a known drug from a completed test;
• Falsifying other chemists’ initials on quality control/confirmatory documents;
• Falsely certifying having run quality control/confirmatory test samples;
[434]*434• Failing to properly calibrate her scales to ensure the accuracy of the drug weights measured by the chemist; and
• Communicating directly with prosecutors about specific cases.
See OIG Report.
There is no evidence in this case, however, that Dookhan tampered in any way with the samples submitted to the laboratory from the sales by Hampton.
B. Procedural Background
All the defendants in this case were indicted on one count of knowingly and intentionally conspiring to distribute fifty or more grams of cocaine base, in violation of 21 U.S.C. §§ 846 and 841(a)(1) and (b)(1)(A). Criminal Compl., ECF No. 1. All three defendants were arrested on September 3, 2009. Arrest Warrants, ECF Nos. 10, 11, 12. Clark and Brown pled guilty on February 10, 2011. Elec. Clerk’s Notes, February 10, 2011. Clark was sentenced to time served (four days) plus twenty-four months of supervised release. Elec. Clerk’s Notes, May 19, 2011. Brown was sentenced to a term of imprisonment of sixty months, followed by four years of supervised release. Elec. Clerk’s Notes, March 28, 2011.
After initially pleading not guilty, Hampton subsequently changed his plea on April 27, 2011. Elec. Clerk’s Notes, April 27, 2011. Prior to the plea hearing, the government provided Hampton with certificates of analysis reflecting that the substances recovered from the controlled purchases contained cocaine base.2 Def. Br. 2. At the change-of-plea hearing, the government argued in front of Judge Nancy Gertner that she ought impose a statutory minimum sentence of ten years because more than 280 grams of crack cocaine were attributable to Hampton.3 See Change Plea Hr’g Tr. (“Plea Tr.”) 4, ECF No. 78. Hampton’s counsel made clear at the hearing that although Hampton was pleading to the conspiracy, he was not pleading to “any particular transaction or any particular amount [of cocaine base] at this point.” Id at 8-9. Judge Gertner informed Hampton that the “precise amounts [of crack cocaine] that you’re responsible for ... will be something we will figure out at sentencing.” Id at 9.
Judge Gertner thoroughly informed Hampton of the rights he was giving up by pleading guilty. Id at 5. In exchange for Hampton’s guilty plea, the government agreed not to seek enhancements based on prior convictions and agreed to recommend a sentence no higher than the mandatory minimum. See id at 6. The government also agreed to recommend that a sentence imposed on Hampton for revocation of a previously imposed supervised release run concurrently with the sentence imposed by Judge Gertner. Id at 6-7. Judge Gertner asked Hampton if he was “pleading guilty because you are guilty and for no other reason,” to which Hampton responded ‘Tes, ma’am.” Id at 9. At no point did Hampton contend that any of the substances recovered in connection with his case were not cocaine base, nor does he now. See Supplemental Mem. 2.
At . the sentencing, Judge Gertner accepted the computations of crack cocaine from the Presentence Report, which calculated the substance attributable to Hamp[435]*435ton to exceed 280 grams. See Sentencing Tr. 3, 18, 21, ECF No. 76. Taking care to note her personal opinion that the congressionally imposed sentencing disparities between cocaine powder and cocaine base were “inhumane,” id. at 17, Judge Gertner sentenced Hampton to the mandatory minimum of ten years, followed by sixty months of supervised release,4 id. at 19; J. Criminal Case 2-3, ECF No. 73. Judge Gertner specifically noted that without a statutory minimum, she would have imposed a sentence on Hampton corresponding to a sentence comparable for cocaine powder, which would have been 70-87 months. Sentencing Tr. 18-19.
On August 10, 2011, Hampton appealed his sentence to the First Circuit Court of Appeals. Notice Appeal, ECF No. 74. Hampton subsequently moved to dismiss his appeal, and the First Circuit granted the motion. Judgement USCA, ECF No. 80. The case was transferred to this Session on November 13, 2012. Notice Reassignment, ECF No. 83.
Hampton filed the instant petition on August 21, 2013. Def. Br. The government opposed on September 5, 2013. Govt. Br. Hampton replied on October 25, 2013, Reply Gov’t’s Opp’n Mot. Vacate, ECF No. 95, and supplemented his petition with new legal and factual developments on May 9, 2015, Supplemental Mem.5 This Court heard oral argument on the petition on May 11, 2015. Elec. Clerk’s Notes, ECF No. 116.
II. LEGAL STANDARD
Title 28 U.S.C. § 2255 allows a federal prisoner to collaterally attack his or her sentence if it “(1) was imposed in violation of the Constitution, or (2) was imposed by a court that lacked jurisdiction, or (3) exceeded the statutory maximum, or (4) was otherwise subject to collateral attack.” David v. United States, 134 F.3d 470, 474 (1st Cir.1998). The fourth, catchall category requires a showing of error that reveals “fundamental defects which, if uncorrected, will result in a complete miscarriage of justice.” Id. (internal quotation marks and alterations omitted). A viable Section 2255 attack must reveal “exceptional circumstances” demanding redress, and the burden is on the petitioner to make this showing. Id.
III. ANALYSIS
Hampton argues that the Court ought vacate his sentence because the prosecutor’s failure to disclose Dookhan’s misconduct tainted his sentencing record in violation of Ferrara v. United States, 456 F.3d 278 (1st Cir.2006), and violated his right to Due Process under Brady v. Maryland, [436]*436373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963). Def. Br. 20-32. Of the federal courts to have addressed post-conviction petitions under Brady and Ferrara in the wake of the Dookhan scandal, not one has vacated a guilty plea. United States v. Wilkins, 943 F.Supp.2d 248 (D.Mass.2013) (Stearns, J.) (“Wilkins I”), aff'd, 754 F.3d 24 (1st Cir.2014) (“Wilkins II”) and 755 F.3d 6 (1st Cir.2014); United States v. Snow, No. 11-cr-10299-DJC, 2015 WL 2226233 (D.Mass. May 11, 2015) (Casper, J.); United States v. Tooley, No. 10-cr-0157-DJC, 2015 WL 566953 (D.Mass. Feb. 11, 2015) (Casper, J.); United States v. Gray, 79 F.Supp.3d 317, No. 10-cr-10075-PBS, 2015 WL 178450 (D.Mass. Jan. 14, 2015) (Saris, C.J.); United States v. Smith, 66 F.Supp.3d 247 (D.Mass.2014) (Gorton, J.); United States v. Jackson, 54 F.Supp.3d 102 (D.Mass.2014) (Saris, C.J.); United States v. Chin, 54 F.Supp.3d 87 (D.Mass.2014) (Saris, C.J.); United States v. Smith, No. 09-cr-10006-RGS, 2013 WL 6798931 (D.Mass. Dec. 20, 2013) (Stearns, J.).
What none of these cases address, however, is a request for post-conviction relief when a statutory mandatory minimum sentence was — at least as the law stands after Alleyne — unconstitutionally imposed based on a drug quantity weighed by Dookhan. The Court does so now.
A. Egregious Government Misconduct (Ferrara v. United States)
Hampton argues that Dookhan’s egregious misconduct renders his sentence “inherently unreliable.” Def. Br. 25. To support his argument, he attempts to apply Ferrara v. United States, in which the First Circuit established a two-pronged test for when a court should set aside a guilty plea as involuntary:
First, [the defendant] must show that some egregiously impermissible conduct (say, threats, blatant misrepresentations, or untoward blandishments by government agents) antedated the entry of his plea.
Second, he must show that the misconduct influenced his decision to plead guilty or, put another way, that it was material to that choice.
Ferrara, 456 F.3d at 290 (internal citations omitted) (citing Brady v. United States, 397 U.S. 742, 755, 90 S.Ct. 1463, 25 L.Ed.2d 747 (1970)).6
Ferrara is the focus of the vast majority of habeas cases that have flowed from the Dookhan scandal. As the government correctly points out, however, Ferrara is inapplicable to Hampton’s case because Hampton does not assert that had he known of the Dookhan scandal, he would not have pled guilty to the offense. Govt. Br. 21. Moreover, because Hampton did not concede at the plea hearing that he distributed more than 280 grams, he cannot claim he involuntarily pled to the quantity of drugs. For this reason, Ferrara is inapplicable to this case.
B. Prosecutor’s Duty to Disclose Exculpatory Evidence (Brady v. Maryland )
Hampton also seeks to vacate his sentence because the government failed to [437]*437disclose Dookhan’s misconduct in accordance with its obligations under the Due Process Clause. In Brady v. Maryland, the Supreme Court held that suppression by the government of evidence favorable to the defendant violates due process when the evidence is material either to guilt or to punishment. 373 U.S. 83, 87, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963). This obligation applies irrespective of the good faith or bad faith of the prosecution, id., and extends to evidence tending to exculpate due only to its tendency to impeach the credibility of government witnesses, United States v. Bagley, 473 U.S. 667, 105 S.Ct. 3375, 87 L.Ed.2d 481 (1985).
In another Dookhan case in which the defendants sought to vacate their guilty pleas, Judge Stearns held that Brady was not material to the case because Brady is a trial rule and does not come into play when a defendant makes a knowing and intelligent guilty plea. Wilkins I, 943 F.Supp.2d at 255. The instant case differs from Wilkins I, however, in that Hampton’s habeas petition is not about his own behavior in making a plea but is about the actual evidentiary basis provided by the government for the imposition of a mandatory minimum. Supplemental Mem. 2. Brady therefore remains open to Hampton.
To establish a Brady violation, “the evidence at issue must be favorable to the accused, either because it is exculpatory, or because it is impeaching; that evidence must have been suppressed by the State, either willfully or inadvertently; and prejudice must have ensued.” Strickler v. Greene, 527 U.S. 263, 281-82, 119 S.Ct. 1936, 144 L.Ed.2d 286 (1999). “Favorable evidence is material ... if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different.” Kyles v. Whitley, 514 U.S. 419, 433, 115 S.Ct. 1555, 131 L.Ed.2d 490 (1995) (internal quotation marks omitted). To constitute a Brady violation, the evidence can be material either to guilt or punishment. Brady, 373 U.S. at 87, 83 S.Ct. 1194.
1. Prejudice7
As is true in all of the Dookhan cases that have been heard in federal courts in this district, there is no indication in the record that Dookhan tampered with evidence in this case. Rather, the argument Hampton puts forth is that Dookhan’s general malfeasance, including her failure properly to calibrate scales and the fact that she co-mingled evidence collected from multiple cases, renders unreliable her signature on the drug certificates. See Supplemental Mem. 2.8 Hampton essential[438]*438ly argues that without the drug certificates, he “would not have been subject to the 10-year mandatory minimum.” Def. Br. 22.
The government argues that the record presents more than enough circumstantial evidence for the ten-year sentence to stick. For support, the government points out that there is no indication anywhere in the record that the substances were counterfeit. Govt. Br. 17. The government also reminds the Court that Hampton admitted under oath in the plea hearing that he conspired to distribute crack cocaine. Id. In addition, some of the samples Hampton sold were field tested, two samples were tested by another lab, and four samples were tested at the state lab by other chemists' — and none of these tests concluded that the substances were anything other than cocaine base. Id. at 18. The consistency of these samples, the government says, is a strong indicator that all of the samples (weighing a collective 350 grams) taken from Hampton during the controlled sales were crack cocaine. Id. at 1, 18.
In another case in which a defendant who did not plead guilty had the misfortune of drawing Dookhan as a chemist, Judge O’Toole held that there had been no Brady violation because the defendant had failed to demonstrate prejudice. Brown, 2015 WL 1268159, at *4. Judge O’Toole based this holding in part on the fact that subsequent retesting of the drugs confirmed the accuracy of Dookhan’s testing. Id. In this case, by contrast, there has been no reweighing of the substances, thus depriving this Court of concrete facts upon which it can conclude that there was no prejudice to Hampton.
Finally, it is significant to note that Judge Gertner imposed this sentence reluctantly based on the statutory mandatory minimum corresponding to the 280 grams. See Sentencing Tr. 21 (observing the unfairness of the disparity between mandatory sentences for selling crack cocaine and cocaine powder). There is thus á reasonable probability that, had Judge Gertner known of the Dookhan scandal and that Dookhan had worked on roughly two-thirds of the 400 grams attributed to Hampton, see Def. Br. 2-3, 24, the outcome of Hampton’s sentencing would have been different. This Court would therefore be warranted in holding that Hampton has met the prejudice element of the Brady analysis.
2. Did the State Suppress Evidence?
There is no allegation in the papers that the prosecutors knew of Dookhan’s misconduct at the time Hampton pled guilty. Indeed, the first communication about the misconduct to any prosecutors took place almost a year after Hampton pled guilty. [439]*439See Def. Br., Ex. I, Letter from Linda Han, ECF Ño. 91-10. A pivotal issue then, is whether Dookhan’s conduct can be imputed to the U.S. Attorney’s Office.
To comply with Brady, “the individual prosecutor has a duty to learn of any favorable evidence known to the others acting on the government’s behalf.” Kyles, 514 U.S. at 437, 115 S.Ct. 1555. This is so because the government’s interest “in a criminal prosecution is not that it shall win a case, but that justice shall be done.” Strickler, 527 U.S. at 281, 119 S.Ct. 1936 (internal quotations omitted).
In a non-Brady case, Judge Woodlock was called upon to decide whether a state police officer who was assisting the Drug Enforcement Agency was part of the federal “prosecution team.” United States v. Mannarino, 850 F.Supp. 57, 65 (D.Mass.1994) (Woodlock, J.). Citing to the Fifth Circuit, Judge Woodlock noted that “[i]m-posing a rigid distinction between federal and state agencies which have cooperated intimately from the outset of an.investigation would artificially contort the determination of what is mandated by due process. Rather than endorse a per se rule, we prefer a case-by-case analysis of the extent of interaction and cooperation between the two governments.” Id. (quoting United States v. Antone, 603 F.2d 566, 570 (5th Cir.1979)) (internal quotation marks omitted). Judge Woodlock noted that “the liability of a principal is affected by the knowledge of an agent concerning a matter as to which he acts within his power to bind the principal or upon which it is his duty to give the principal information.” Id. at 66 (quoting Restatement (Second) of Agency (1958), § 272) (internal quotation marks omitted). Judge Woodlock found that the state police officer was “clothed by the DEA with the indicia of agency,” and he therefore imputed the state police officer’s action to the prosecution team. Id.
In the context of the Dookhan cases, the First Circuit has expressly reserved the question of whether Dookhan, a laboratory worker employed by the Commonwealth, should be considered part of the federal “prosecution team.” United States v. Brown, 2015 WL 1268159, at *4 (D.Mass. Mar. 19, 2015) (citing Wilkins II, 754 F.3d at 28). The only Massachusetts District Court judge to address the issue in the context of Dookhan is Judge Stearns, who stated in dicta that “[wjhile no case in the First Circuit specifically addresses the federal government’s exculpatory duty with respect to impeaching evidence involving a state-employed witness like Dookhan, the safer course is to assume that the duty attaches.” Wilkins I, 943 F.Supp.2d at 255 n. 9.9
It was against this background that the Court convened the habeas petition hearing on May 11, 2015. Early on during that hearing, I floated the idea of an evidentiary hearing to sort out Dookhan’s relationship to the prosecution team in this case and how she had handled the alleged crack cocaine seizures in this case — and was met with stonewalling:
AUSA: [TJhis matter comes to you as a 2255 and it seems to me what you’ve got to do is to determine, based on the record, whether there’s prejudice or not, and you may not like a PSR generally, but that’s what the record is.
Court: Well, of course, it’s part of the record. Errors are made. We now know things we did not know. Surely [440]*440I can hold an evidentiary hearing. And I’m suggesting that the best justice may be to hold done. And at such hearing either you stipulate or you prove your direct evidence case, which is six such sales, and your circumstantial evidence case in which you’re asking me to infer that given the other sales the weight would have been, and if I add them all up, they’d be above the 280 grams. I understand how to hold such a hearing, it doesn’t need to be long, but it needs to be evidence, not — and I mean no disrespect to the probation officers, but the probation officers put in a presentence report, which is what the government tells them to get ready for sentencing. I need an evidentiary hearing on which I can make findings. I can’t make findings on a PSR. And so that’s what I’m thinking.
AUSA: [I]f that’s what the Court feels it needs to hold for the government, I am suggesting to you that the government doesn’t want to expend those resources to defend that. I think the record is sufficient for the Court to make a finding that there was no prejudice here. I don’t want to spend another, um — ....
Unofficial Transcript 12-14.
In thirty years of federal judicial service, I have frequently seen the government trim its sails as it plea bargains to avoid the expense of actually proving its contentions, but never before have I seen it decline to defend a conviction with actual evidence. This obdurate refusal even to defend a minimum mandatory sentencing procedure that is today unconstitutional against a background of undoubted criminal misconduct in the handling of evidence — misconduct that raises troubling questions about the accuracy of the sentence before the Court — raises two interrelated questions.
First, is it within the discretion of the Court, notwithstanding the First Circuit’s caution not to hold unnecessary evidentiary hearings in habeas proceedings, see Pike v. Guarino, 492 F.3d 61, 70-71 (1st Cir.2007), to hold one here? The answer is yes. Mannarino, 850 F.Supp. at 60 (holding, after an evidentiary hearing, that state police officer was a member of the federal prosecution team); see also Commonwealth v. Sleeper, 435 Mass. 581, 605, 760 N.E.2d 693 (2002) (discussing a case in which the motion judge decided after an evidentiary hearing that government witness was not a member of the prosecution team, and therefore ruling that there was no Brady violation).
Second, is it reasonable (and just) in light of the government’s refusal to confront the issue by way of evidence or even briefing to infer that, in the unique circumstances of this unusual case, Dookhan was a member of the prosecution team? Again, the answer is yes.
III. CONCLUSION
For the reasons articulated above, therefore, the Court ALLOWS Hampton’s motion to vacate his sentence (but not his conviction) and DENIES the government’s request for summary dismissal. The following parameters will govern Hampton’s resentencing:
A. No minimum mandatory sentence shall be imposed since to do so would be unconstitutional. Alleyne, 133 S.Ct. at 2158.
B. In accordance with United States Sentencing Commission, Guidelines Manual, § 1B1.11 (Nov.2014), the guidelines presently in effect shall govern the resentencing.
[441]*441C. Hampton’s new sentence shall not exceed his present sentence since to do so would be vindictive. See Bridgeman v. Dist. Attorney for Suffolk Dist., 471 Mass. 465, 477, 30 N.E.3d 806 (2015).
D. All the provisions of Hampton’s plea bargain remain in full force and effect.
SO ORDERED.
