*1082 OPINION
In a case of first impression, we examine whether a district court may, over defense objection and after the administration of an unsuccessful Allen 1 charge, inquire into the reasons for a trial jury’s deadlock and then permit supplemental argument focused on those issues, where the issues in dispute are factual rather than legal. We conclude that allowing such a procedure in a criminal trial is an abuse of the discretion accorded district courts in the management of jury deliberations.
I. Facts & Trial Proceedings
Defendant Calvin Bryan Evanston (“Evanston”) was charged with assault resulting in serious bodily injury under 18 U.S.C. §§ 1153 and 113(a)(6) occurring within the Colorado River Indian Tribes reservation in western Arizona. There is no dispute that an assault occurred and that the victim, Evanston’s live-in girlfriend, suffered serious bodily injury. 2 When interviewed, Evanston first claimed he returned home after being away for most of the day, only to find his girlfriend lying on the bed covered in blood. He later changed his story, telling investigators that he came home to see a man leaving the house and his girlfriend partially undressed. Believing she was cheating on him, he slapped her, the unexpected force of the blow spinning her to the ground. On the way down, according to Evanston, her face struck the night stand. 3
During a two and one-half day trial, the victim identified Evanston as her assailant and disputed his version of events. There was, she testified, no other man in the house before or during the incident, and her injuries were not the result of a single slap, but rather of Evanston’s grabbing her throat, restricting her airways, and hitting her. She remembered Evanston striking her, though she could not remember how many times. She remembered feeling a sharp pain in her face, but could not remember anything that happened between suffering the blow and waking up in the hospital.
After five hours of deliberation over two days, the jury advised that it could not reach a verdict. The district court then gave Ninth Circuit Model Jury Instruction 7.7 — commonly referred to as an Allen charge, deadlock instruction, or “dynamite charge” 4 — and asked the jury to continue to deliberate.
*1083 After almost three hours of additional deliberation, the jury again advised that it was deadlocked. At this point, the district court met with counsel outside the presence of the jury and stated: “I’m informed that other judges in this courthouse, when defendants desire it, are perfectly happy to bring in the members of the jury, ascertain the issue on which they are deadlocked, and allow ten more minutes to each side to argue that point and send the jurors back to redeliberatе.” While the government welcomed the opportunity to “get to the heart of whatever their ... disagreement is,” Evanston’s counsel objected to the proposed process, noting that evidence was closed and that the defense had no desire to reargue or to allow the government to do so.
Noting a reluctance to do so over the defense objection, the district court called the jury back and asked if “the procedure of, without adding additional evidence, identifying particular points and rearguing those points might assist them in resolving the impasse.” The jury agreed and identified two issues: witness credibility and how the victim’s injuries were caused. The district court did not permit further elaboration on either point, allow the jury to identify which witness’s credibility it questioned, or ask any questions as to the number or nature of the split, but excused the jury to allow counsel to proffer additional arguments in favor or against using the reargument procedure. The defense repeated its earlier objections, arguing that the evidence adduced by the government simply had not met its burden of providing the jury with the answers to its questions.
Despite these renewed objections — and reasoning that the procedure would avoid manifest necessity to declare a mistrial— the district court decided it would allow both sides an opportunity to address the jury on the identified issues. The government presented its supplemental closing argument first, and the defense followed. After two more hours of deliberation, the jury returned a unanimous guilty verdict.
Evanston appeals that verdict, arguing that the district court’s actions in questioning the jurors as to the subject of their deadlock and allowing supplemental argument on those factual issues invaded the jury’s role as the sole fact-finder.
II. Standard of Review
As an issue of first impression in this circuit, there is no authority identifying a specific standard for reviewing the decision to allow supplemental argument. Because matters of trial management are typically reviewed for abuse of discretion,
United States v. Goode,
III. Discussion
A. Discretion, Coercion, and the Traditional Roles of the Judge and Jury
District courts are accorded substantial discretion in the control of jury deliberations.
See, e.g., Bollenbach v.
*1084
United, States,
Accordingly, and because “[t]he influence of the trial judge on the jury is necessarily and properly of great weight and his lightest word or intimation is received[by the jury] with deference, and may prove controlling!,]”
Quercia,
Extraordinary caution must be exercised when acting to break jury deadlock. This is particularly true with respect to the court’s actions in giving an
Allen
charge, which we have recognized as already “standing] at the brink of impermissible coercion.”
United States v. Sea-well,
In keeping with these principles, we have held that it is per se error to give a second
Allen
charge where the jury has not requested one, because it conveys a message that “the jurors have acted contrary to the earlier instruction as that instruction was properly to be understood. (‘Apparently you didn’t listen to what I said before, so I’ll repeat it.’),” and that message serves no purpose other than impermissible coercion.
Seawell,
Viewing the district court’s procedure against these core principles, we now turn to the particular factors contributing to our decision.
B. Factual vs. Legal Argument
In
Ayeni,
the only reported circuit decision on the practice of allowing supplеmental argument, the defendant was charged with conspiracy to defraud through the taking of vouchers meant to compensate
*1086
trial witnesses.
After determining that the jury’s concerns could have been addressed with short, neutral answers, the D.C. Circuit held:
[gjiven these other options, it was an abuse of discretion for the district court to adopt an approach that, in effect, allowed the lawyers to hear the jury’s concerns and then, as if they were sitting in the jury room themselves, fashion responses targeted precisely to those concerns.
Id. at 1316.
Ayeni did not go so far as to hold that supplemental argument should never be allowed because such a practice always invades the jury’s fact-finding prerogative. However, noting that this jury trial innovation was “almost unheard of’ in the judiciary, 9 the D.C. Circuit strongly discouraged its use where the reason for the jury’s inability to agree is based on а factual matter, rather than confusion about a legal standard. Id. at 1317 (noting the parties had cited only a single case in which supplemental arguments were used).
In a concurring opinion, Judge Tatel expressed a stronger view of the impropriety of using such a procedure, arguing that supplemental argument should never be used in response to a jury’s factual question because the practice allows lawyers the opportunity to, in effect, participate in the jury’s deliberations. Id. at 1318-19.
Here, the government argues that the district court had broad discretion to allow supplemental arguments, consistent with the Supreme Court’s statement in
Bollenbach
that “[w]hen a jury makes explicit its difficulties a trial judge should clear them away with concrete accuracy.”
Indeed, the sentence immediately preceding the passage cited by the government for its broad proposition makes clear that the court there contemplated a trial court’s response to the jury’s confusion about the relevant
legal
standards: “Discharge of the jury’s responsibility for drawing appropriate conclusions from the testimony depended on discharge of the judge’s responsibility to give the jury the required guidance by a lucid statement of the relevant
legal criteria.” Bollenbach,
We have previously cautioned that [b]ecause the jury may not enlist the court as its partner in the fact-finding process, the trial judge must proceed circumspectly in responding to inquiries from the jury. The court may properly attempt to avoid intrusion on the jury’s deliberations by framing responses in terms of supplemental instructions rather than following precisely the form of question asked by the jury.
Walker,
We think this caution applies with equal force to the placement of attorneys in such a role. Allowing the attorneys to argue further on factual matters after the jury retired to deliberate, over defense objection, was akin to allowing a witness to provide an opinion as to how to weigh evidence presented, which is categorically proscribed.
Cf. United States v. Stephens,
The supplemental arguments here intruded upon the jury’s fact-finding role in two ways and through two conduits: (1) the judge’s questioning as to the reasons for the deadlock required that the jury divulge the state of its unfinished deliberations, thereby violating the jury’s deliberative secrecy,
Ayeni,
Thus, though we do not foreclose the possibility that supplemental argument treating factual matters could ever be used, its employment here resulted in an impermissible intrusion into the jury’s role as the sole fact-finder.
C. Absence of Formal Adoption
Judge Tatel’s
Ayeni
concurrence also noted that it would be particularly inappropriate to allow the practice of supplemental argument as an ad hoe rule of practice, arguing that any such jury trial innovation should first be subject to a formal rulemaking or legislative procedure— such as an amendment to the rules of criminal procedure — which “would permit the kind of rigorous and thorough examination of the benefits and drawbacks of supplemental arguments that so novel and untested a change in longstanding jury procedures requires.”
While we do not rest our holding squarely on this point, we agree that absence of formal adoption throws a further shadow upon the practice. In this circuit, the first step of allowing supplеmental argument on factual matters — asking a jury to identify its concerns — is not only not authorized by current rule, 11 it seems to run contrary to Ninth Circuit Model Jury Instruction 7.6, in which the district judge tells the jury: “Remember that you are not to tell anyone — including me — how the jury stands, numerically or otherwise, on any question submitted to you, including the question of the guilt of the defendant, *1089 until after you have reached a unanimous verdict or have been discharged.”
Further, the Ninth Circuit’s Jury Trial Improvement Committee has considered and adopted several jury trial innovations focused on streamlining jury service and improving the efficiency of jury trials within the circuit. See Ninth Circuit Jury Trial Improvement Committee, First Report on Goals and Recommendations (2004); Ninth Circuit Jury Trial Improvement Committee, Second Report: Recommendations and Suggested Best Practices (2006). Among other recommendations, the committee suggested several best practices for improving juror comprehension during the trial process, including: (1) permitting juror note-taking during trial; (2) permitting written questions from jurors during civil trials; (3) providing all jurors with both preliminary and final jury instructions in written form; (4) randomly selecting alternate jurors after closing arguments and instructions; (5) encouraging attorneys to use technology for the presentation of trial exhibits; and (6) permitting juror discussion of evidence as civil trials progress. Ninth Circuit Jury Trial Improvement Committee, Second Report at 10-13.
The committee even recommended that interim statements be made during the course of civil trials to help jurors better comprehend and remember facts. Id. at 13-14. Notably absent from the committee’s reports and recоmmendations, however, is the procedure of allowing supplemental argument addressing factual issues, either alone or in conjunction with a deadlock instruction. Such procedure simply has not been vetted through any formal process in our circuit — or, to our knowledge, in any sister circuit.
We are aware that at least three states have adopted rules specifically allowing for additional or supplemental closing argument in criminal cases where juries indicate that they have reached an impasse in their deliberations.
See
Ariz. R.Crim. P. 22.4 (Arizona); Cal. R. Ct. 2.1036 (California); N.D.R. Ct. 6.9 (North Dakota). Arizona’s rule — the first to explicitly allow for supplemental closing arguments of this nature — was adopted as an alternative means of addressing jury questions and impasse,
see
Ariz. R.Crim. P. 22.4 cmt. to 1995 Amendments;
State v. Fernandez,
But each of these states has had the benefit of the formal rulemaking process to weigh the benefits and risks of allowing supplemental argument. The federal courts have not. While we recognize that the implementation of jury trial innovations may provide for increased judicial economy — a benefit our circuit in particular appreciates — we do not believe that any such radical innovation should be sanctioned without the formal vetting normally attendant to the adoption of an official rule or legislative enactment.
See Pan Am. World Airways,
D. Alternatives to Supplemental Argument
Further influencing our finding that ordering supplemental argument resulted in an abuse of discretion here is the fact that — -as in Ayeni — the district court had in its arsenal of permissible actions numerous less coercive alternatives, including doing nothing at all.
Here, the district court could merely have reread the original jury instructions relating to each area of concern.
See Johnson,
The original jury instructions relating to causation were less extensive; they included only a statement that, in order to find Evanston guilty, the jury must have found that he “intentionally struck or wounded [the victim,]” and, “as a result, [the victim] suffered serious bodily injury!.]” The plain language of this instruction appears clear enough that repetition could have resolved the jury’s concern, but if the jury required further direction as tо what constituted causation, the court could have responded by providing supplemental instruction further illuminating the relevant legal standard.
12
Walker,
If repetition or supplemental instruction did not suffice to address the jury’s concerns, the court could also have offered to allow the jury to review portions of witness testimony, a procedure typically used where the jury requests review of a particular witness’s statements.
Cf United States v. Sandoval,
These available trial procedures have benefited from thorough vetting and approval in federal courts, greatly reducing the risk of jury coercion. Yet rather than choosing one of these alternatives or declaring a mistrial in the face of the jury’s indication of a second deadlock, the trial court here struck a path through the uncharted territory of supplemental factual argument. We recently clarified that a trial judge is not required to consider or employ
any
alternatives to declaring a mistrial when a jury reports it is at an impasse, because “cоnceivable ‘alternatives’ present a serious risk of coercing jurors[.]”
Harrison v. Gillespie,
Thus, it is clear that the district court was not required to avoid mistrial at all costs, particularly where the novel procedure employed ran a significant risk of undermining the defendant’s due process rights to a fair trial and impartial jury. Yet when the district court brought the jury in to determine whether additional argument might aid them in reaching a verdict, it made the following statement: “Both parties have a right to make sure that the judge and others do their very best to make sure that the jury empanelled [sic] to hear a case absolutely cannot decide it ... before they declare a mistrial or release the jury.”
Because the jury had already been sent back to deliberate after receiving the deadlock instruction, and because the district court told the jury it was required to do all it could before declaring a mistrial, it seems clear that this commentary and the supplemental closing arguments risked the same type of coerсion and prejudice contemplated by
Seawell. See
E. Additional Considerations
In addition to doubting that supplemental arguments on factual matters, post-
Allen
charge, could ever escape an undue risk of coercion, we note that a court’s actions in employing multiple means of overcoming jury deadlock pose a significant risk of impermissibly shifting the government’s burden of proof in violation of the defendant’s due process rights. It is beyond comment that the government bears the burden of proving the defendant’s guilt beyond a reasonable doubt at trial.
Sullivan,
F. Prejudice
It would be inappropriate to find harmless error here, as there is no way to know whether supplemental argument produced thе jury’s verdict.
See Ayeni,
Additionally, before proceeding with the presentation of supplemental arguments, the district court here neither reminded the jurors that they should not surrender their hоnestly held convictions in order to reach a unanimous verdict
14
nor admonished them that they should give full consideration to the entirety of the evidence presented, rather than focusing unduly on the evidence referenced in the supplemental arguments. We have found uncured prejudice requiring reversal where courts failed to use these types of remedial procedures in parallel contexts.

criminal defendant ... being tried by a jury is entitled to the uncoerced verdict of that body.”

Notes
. An
Allen
charge, the original concept of which was approved by the Supreme Court in
Allen v. United States,
. The victim’s injuries — including a nasal fracture, an orbital floor fracture, and a broken jaw — required air evacuation to a level one trauma center in Phoenix and extensive surgery to repair and rebuild the victim's face, including the placement of several screws and plates. The injuries affected the victim's balance and left her with permanent scarring. She still suffers from nerve damage.
. The jury heard Evanston’s side of the story through statements given to law enforcement. The district court held a pre-trial evidentiaiy hearing and concluded that Evanston's various statements to law enforcement were either preceded by, or did not require, proper Miranda warnings. In a separate memorandum disposition accompanying this opinion, we affirm those rulings.
. "In thеir stronger forms, these charges have been referred to as 'dynamite charges,' because of their ability to ‘blast’ a verdict out of a deadlocked jury.”
United States v. Mason,
. It was in view of the fundamental sanctity of the jury’s deliberative process and the attendant necessity of deliberative secrecy that we recently reversed the denial of a habeas corpus petition in
Williams v. Cavazos,
no one, including the judge, is even supposed to be aware of the views of individual jurors during deliberations, because a jury’s independence is best guaranteed by secret deliberations, such that jurors may 'return a verdict freely according to their conscience' and their ‘conduct in the jury room [may be] untrammeled by the fear of embarrassing publicity.'
Id.
at 643-44 (alterations in original) (quoting
Clark v. United States,
. Indeed, the government has previously conceded that “the principle that jurors may not be coerced into surrendering views conscientiously held is so clear as to require no elaboration.”
Jenkins v. United States,
. The use of
Allen
charges has been so strongly "criticized as constituting an unwarranted intrusion upon the province of the jury” that several of our sister circuits have completely barred their use, opting instead for other forms of instruction.
Nickell,
.In a similar exercise of its supervisory powers, the Supreme Court also proscribed inquiry into the numerical division of the jury.
Brasfield v. United States,
. To dale, no reported federal court decision has sanctioned the use of supplemental argument on factual questions in a criminal trial.
. We recognize that this circuit allows for supplemental argument in some cases where supplemental instructions have been given.
United States v. Fontenot,
. None of the Federal Rules of Criminal Procedure relating to jury deliberations, closing arguments, or communications with the court mentions, let alone sanctions, the use of supplemental arguments to address a jury’s factual questions. See, e.g., Fed.R.Crim.P. 26.3 (requiring that court give each party the opportunity to object to the propriety of declaring mistrial), 29.1 (mandating the order of closing arguments), 31(d) (allowing parties to request jury poll before jury is discharged in order to verify unanimity). At the very most, Federal Rule of Criminal Procedure 26.3 allows parties to recommend “alternatives” to the declaration of a mistrial; there is no language approving the use of supplemental closing arguments where no new evidence or theory has been introduced.
. As we noted above, had the court provided a supplemental instruction which introduced a new legal theory, supplemental argument on that theory might have been permissible or even required in order to avoid prejudice.
Fontenot,
. A similar situation arises when a court dismisses a holdout juror for believing the evidence presented is insufficient to support the charged offense; allowing another juror to take his place eviscerates the constitutional balance struck by the parties’ allocated burdens of proof.
Cf. Williams,
. The district court did instruct the jurors not to “change an honest belief as to the weight or effect of the evidence solely becаuse of the opinions of your fellow jurors, or for the mere purpose of returning your verdict” during the-course of administering the deadlock instruction. It did not, however, repeat this cautionary instruction before, during, or after the supplemental arguments.
. Although we have serious doubts as to whether inquiry into the reasons for a deadlocked jury's division, and allowance of additional argument on factual issues tailored to those concerns over the objection of the defendant, could ever be conducted in such a manner as to avoid impermissible coercion, we do not reach today the question of whether the use of supplemental arguments to address factual matters is necessarily or always an error of constitutional dimension, whatever the cirсumstances. Rather, we hold that, under the circumstances presented here, the district court’s actions resulted in impermissible coercion, and consequently an abuse of discretion meriting reversal. We so limit our holding because the Supreme Court’s precedent on similar jury coercion issues has generally emanated from its supervisory powers over the federal courts, rather than any mandate from the federal Constitution.
See Lowenfield,
. Evanston's challenge to his sentence is rendered moot by this opinion.
