    Sarah George, Chittenden County State’s Attorney, Pamela Hall Johnson, Deputy State’s
    Attorney, and Jacob Oblak, Legal Intern, Burlington, for Plaintiff-Appellee.
    Matthew Valerio, Defender General, and Dawn Matthews, Appellate Defender, Montpelier, for
    Defendant-Appellant.
    PRESENT: Reiber, C.J., Skoglund, Robinson, Eaton and Carroll, JJ.
    ¶ 1.   CARROLL, J.        Defendant appeals his conviction for first-degree aggravated
    domestic assault. He argues that the trial court denied him the right to a fair trial by refusing to
    grant immunity to his witness or to compel the State to do so. In addition, he submits that the trial
    court’s supplemental instruction improperly pressured the jury to reach a verdict. We affirm.
    ¶ 2.   Defendant was tried by jury over two days in August 2017 on four counts: first-
    degree aggravated domestic assault; second-degree unlawful restraint; interference with access to
    emergency services; and kidnapping.1 The State relied on complainant’s report that defendant
    1
    Defendant was originally charged with a count of grossly negligent operation with
    serious injury resulting, but the State dismissed this charge prior to trial.
    burned her with a cigarette to satisfy the bodily injury element of the aggravated-domestic-assault
    count.
    ¶ 3.   At trial, defendant and complainant both testified. Complainant testified as follows.
    She and defendant dated in May and June 2016 and during that time defendant promised that he
    would divorce his wife. On July 2, 2016, the couple attended a party where both were drinking.
    They left in defendant’s car to take a friend to the University of Vermont Medical Center
    (UVMMC). At UVMMC, complainant got upset when she noticed that defendant was texting his
    wife. She told defendant she was “done,” and that she wanted to take her belongings out of his car.
    Complainant then described in detail a series of events that resulted in severe injuries to her. The
    two went outside to the parking lot, where their argument escalated. Defendant took complainant’s
    purse and threw it over a construction fence. After she retrieved it, complainant and defendant
    continued to argue. At one point, defendant became physical and pushed her against a wall.
    Complainant walked away from the hospital, continuing to argue with defendant by text message
    and over the phone. She subsequently told defendant that she needed help when she began to have
    an anxiety attack. She texted him that she was near a baseball field, and then passed out.
    ¶ 4.   Complainant woke up some time later to the sound of defendant’s car. When she
    continued to lie still, he came over and pulled her partially up by her hair before kicking her.
    Defendant said he would help her, but that this was the end of their relationship. Still arguing with
    him, she got into the front passenger seat of his car. They continued to fight, and defendant burned
    complainant’s chest with a lit cigarette. Defendant took complainant’s cell phone so that she could
    not call her sister. Defendant got out of the car, and complainant chased after him. Defendant
    threw complainant’s cell phone onto the ground and jumped on it, crushing it into several pieces.
    Defendant returned to the driver’s seat. Complainant grabbed onto the driver’s side door to try to
    keep him from pulling away with her purse and other belongings, and defendant kicked and shoved
    her with his left foot and arm. Defendant stepped on the gas and complainant let go when she
    2
    realized she was being dragged. Defendant hit the brakes just as his back tire rolled over
    complainant’s right arm, causing her to scream. Defendant then came over to her, picked her up,
    and led her back to the passenger’s seat.
    ¶ 5.    Complainant believed that defendant was going to take her back to UVMMC on
    account of her injury, but instead he kept driving. He threatened to kill her and her dog and held a
    box cutter inches from her neck. When he stopped at a storage unit, he tried to force her out of the
    car. She refused to leave, thinking that she would be safer inside the car. When defendant got a
    phone call, complainant screamed for help; defendant hung up the phone right away, punched her
    twice in the head, and continued to drive.
    ¶ 6.    Complainant asked defendant to take her to a restroom. He took her to a gas station
    in Richmond, but she refused to leave the car because he got out to accompany her to the restroom.
    After he saw her reach to grab his cell phone and her credit cards (which defendant had taken),
    defendant hit complainant in the head and threw a bottle at her. Believing this would be her last
    chance to escape before he took her home, where she feared he would kill her, complainant picked
    up the bottle and hit him with it as hard as she could before running out of the car and into the
    station. Once inside, she screamed that her boyfriend was trying to kill her. The attendant pulled
    her behind the counter, locked the door, and called the police. Complainant then remembers passing
    in and out of consciousness before waking up to emergency personnel asking her questions.
    ¶ 7.    Defendant testified that he went to a party with complainant and had to leave to bring
    a friend to the hospital. He stated that complainant became angry when she saw him text “I love
    you” to his wife. Defendant admitted that he threw complainant’s purse over a fence in the hospital
    parking lot. At this point, defendant’s version of the events that evening differed significantly from
    complainant’s. He generally alleged that complainant was drunk and caused her own injuries.
    ¶ 8.    Defendant stated that he agreed to find complainant at the baseball field, and on his
    way, he ran into his friend, Christopher Edwards.         Edwards climbed into the back seat of
    3
    defendant’s car and they found complainant passed out at the baseball field. Defendant roused her
    and got her into the front seat of the car where she continued to complain about defendant’s
    communications with his wife. Defendant began to drive, and complainant opened the car door and
    stepped out of the moving car. She fell, grabbing the side of the car with her left hand as she went
    down. Defendant, realizing that she was being dragged, stopped the car and got out to check on
    her. He found her crying on the ground and estimated that she had been dragged but did not see
    any injuries on her other than some road rash. She asked to go home. She did not say anything
    about defendant running over her arm.
    ¶ 9.    As they continued to drive, however, complainant said her phone had fallen out of
    the car, and she began yelling that she could not feel her arm and needed to go to the hospital. Then
    she told defendant that she needed to use the restroom and he took her to a gas station in Richmond.
    Once there, she said that she no longer needed to go, so defendant prepared to drive away. However,
    complainant then got out of the car, and when defendant asked her what she was doing, she
    responded that she was calling the cops. He asked her why and she said, “You’ll see.” At this
    point, not wanting to have an interaction with the police, and believing that he had done nothing
    “that warranted police,” defendant left to drive Edwards home before going to visit his wife.
    ¶ 10.   Defendant’s witness, Kristi Proper, testified on cross-examination that during a call
    on the night of the incident defendant told her that only he and complainant were in his car.
    ¶ 11.   On the second day of trial, prior to defendant’s testimony, defendant notified the
    court of his intention to call Edwards as a witness. Counsel reported that Edwards had joined
    defendant during his travels between the hospital and the baseball field and would testify that “all
    of the things that [complainant] says are not true, or he’ll testify to events that are different to the
    events that [complainant] testified, to an extent that both versions cannot be true.” Counsel
    indicated that the State had noticed its intention to introduce global positioning system (GPS)
    evidence showing that Edwards, who was on furlough, was not with defendant on the night of the
    4
    incident because his GPS monitor placed him on St. Paul Street at the time in question. The defense
    sought a ruling from the court regarding the admissibility of the GPS evidence and whether the
    State would be permitted to cross-examine Edwards about his furlough supervision.2
    ¶ 12.   In response, the State confirmed that the GPS evidence would show that Edwards
    was not in the vicinity of UVMMC and the baseball field during the time he would testify that he
    was. The State raised a concern that “either Mr. Edwards is going to admit to an escape, or Mr.
    Edwards is going to be perjuring himself” and suggested that the court provide him with legal
    counsel prior to testifying. The court inquired of the defense whether Edwards would testify he
    took off the monitor and left it on St. Paul Street. Counsel replied, “I think I would want to have a
    conversation with Mr. Edwards before I made a proffer to the court.” The court appointed an
    attorney to consult with Edwards.
    ¶ 13.   After meeting with Edwards, his attorney reported to the court that Edwards
    intended to invoke his Fifth Amendment right and refuse to testify if called as a witness. In
    response, defense counsel requested that the court immunize Edwards because “[h]is testimony is
    incredibly exculpatory information for my client” and “[goes] directly to the credibility of the
    complaining witness.”
    ¶ 14.   The State repeated its concern that Edwards would either incriminate himself on a
    felony escape charge, which the State would prosecute, or take the stand and perjure himself by
    lying about being with defendant. It refused to provide immunity to the witness, viewing the
    potential testimony, “in either scenario, to be an extremely serious and potentially, in the State’s
    opinion, a very egregious violation against the integrity of the court.” Defense counsel contested
    whether Edwards could be charged with felony escape, having allegedly been away from his
    2
    The court had previously granted defendant’s motion to exclude evidence of Edwards’s
    criminal record and defense counsel argued that allowing mention of Edwards’s furlough status
    would violate that order.
    5
    apartment for only two to three hours, and argued he would, at most, be subject to a furlough
    violation.
    ¶ 15.   The court denied defendant’s request for court-ordered immunity. It relied on 12
    V.S.A. § 1664 and State v. Haner, 
    2007 VT 49
    , 
    182 Vt. 7
    , 
    928 A.2d 518
    , in concluding that only
    the State is authorized to request the court to order immunity for a witness. The court explained:
    So here, where the court cannot immunize Mr. Edwards from the
    possible threat of prosecution for perjury, and where the State has
    indicated that it has GPS records which would potentially place him
    at a location far away, on St. Paul Street, from the Mobil station in
    Richmond, where it is alleged that he would testify he was present,
    the court believes that there are no policy rationale or reasons that
    would persuade the court that this court should go out on a limb and
    recognize an[] exception where even the Vermont Supreme Court
    has so far declined to do so.
    ¶ 16.   Defense counsel responded to the court’s order, in part, by again describing the
    nature of the testimony Edwards would give, stating that “this testimony would be critically
    exculpatory, perhaps the most powerful and important information that the defense can present to
    the jury to contradict the testimony of the complaining witness.” Out of the presence of the jury,
    Edwards invoked his Fifth Amendment right and refused to testify about his involvement in any of
    the events of the case.
    ¶ 17.   After closing arguments, the court instructed the jury.           Several hours into
    deliberations, the jury sent a note indicating it was deadlocked on count one, the domestic-assault
    charge. The court notified the parties that it would issue a “so-called Allen charge.” Defendant did
    not object. The court then provided additional instructions to the jurors, urging them to make a
    good-faith attempt to reach a unanimous decision. Again, there was no objection. Forty-five
    minutes later, the jury returned with a guilty verdict on the first-degree aggravated-domestic-assault
    charge and not guilty verdicts on the remaining charges.
    ¶ 18.   Defendant filed a motion for judgment of acquittal or new trial, arguing that the
    court erred when it issued the supplemental charge to the jury. The court denied the motion,
    6
    concluding that the supplemental charge did not violate any of defendant’s fundamental rights.
    Defendant filed this appeal.
    I. Witness Immunity
    ¶ 19.   On appeal, defendant first argues that his due process right to present a defense was
    violated when the court refused to grant his witness immunity or to require the State to do so.
    Defendant submits that, despite the language in 12 V.S.A. § 1664, we should look to case law from
    other jurisdictions holding that the trial court may grant immunity to a defense witness in the rare
    instance that it is necessary. Alternatively, he contends that the state’s attorney engaged in
    prosecutorial misconduct either by withholding immunity from Edwards or by making threatening
    statements at trial, leading him to invoke his Fifth Amendment privilege. Defendant argues that,
    because of this prosecutorial misconduct, the court should have required the State to grant Edwards
    immunity as a condition of continuing the prosecution of defendant.
    ¶ 20.   We review the legal questions of whether the trial court had the authority to confer
    immunity or compel the State to do so without deference to the trial court. See State v. Gagne,
    
    2016 VT 68
    , ¶ 13, 
    202 Vt. 255
    , 
    148 A.3d 986
    (explaining that legal questions are reviewed without
    deference). We review the trial court’s application of the applicable test for abuse of discretion.
    See State v. Patten, 
    2018 VT 98
    , ¶ 4, 
    208 Vt. 312
    , 
    197 A.3d 873
    (stating that trial court’s
    discretionary decisions are reviewed for abuse of discretion); State v. Martinez, 
    189 P.3d 348
    , 355
    (Ariz. 2008) (en banc) (“We review the denial of a motion to compel [witness to testify] for an
    abuse of discretion.”).
    A. Judicial Immunity
    ¶ 21.   We first address defendant’s argument that the trial court erred by refusing to grant
    defendant’s witness judicial immunity. The statute governing witness immunity, 12 V.S.A. § 1664,
    provides for witness immunity only when requested by the prosecutor.            Although we have
    previously left unanswered the question of whether a court may, without the State’s consent, extend
    7
    immunity to a third-party witness who invokes the right against self-incrimination, we now hold
    that it cannot.
    ¶ 22.     The Legislature has provided that, “upon the request of the Attorney General or a
    State’s Attorney,” a court may compel a witness to testify notwithstanding the witness’s assertion
    of the Fifth Amendment right against self-incrimination. 12 V.S.A. § 1664(b) (emphasis added).
    This Court has recognized that, with “few and limited” exceptions, “the power to grant witness
    immunity lies exclusively within the discretion of the prosecutor.” Haner, 
    2007 VT 49
    , ¶ 7
    (explaining that exceptions to State’s exclusive authority to grant, or withhold, witness immunity
    “are few and limited in scope so as not to disrupt the separation of powers inherent in the
    Legislature’s exclusive grant of authority to the Attorney General and state’s attorneys”).
    ¶ 23.     We have recognized limited exceptions, crafting an exclusionary rule of sorts to
    enable defendants to testify in certain settings without waiving their right against self-incrimination.
    For example, we held that when a probation-revocation hearing is held before the criminal trial on
    the underlying offense, thereby putting “a probationer in the untenable position of choosing
    between [the] right to due process at the revocation hearing and [the] right to remain silent at
    criminal trial, the probationer’s testimony may not be used against [the probationer] at trial.” 
    Id. ¶ 8
    (citing State v. Begins, 
    147 Vt. 295
    , 297-98, 
    514 A.2d 719
    , 721-22 (1986)). We extended this
    rule to “a situation in which a sex offender who had testified at trial was required by [the] probation
    conditions to admit criminal responsibility at a treatment program, exposing [the offender] to
    potential perjury charges.” 
    Id. (citing State
    v. Cate, 
    165 Vt. 404
    , 415, 
    683 A.2d 1010
    , 1018 (1996)).
    ¶ 24.     Both recognized exceptions involved a defendant “faced with the difficult choice of
    testifying and risking self-incrimination or remaining silent and forfeiting other important rights.”
    
    Id. As we
    noted in Haner, this Court has been cautious in limiting the application of such judicially
    crafted immunity, even for defendants, and has never extended judicially crafted immunity to
    defense witnesses who invoke the privilege against self-incrimination. 
    Id. 8 ¶
    25.   Haner recognized that the Third Circuit had crafted a judicial-immunity exception
    for third-party witnesses in Government of Virgin Islands v. Smith, 
    615 F.2d 964
    (3d Cir. 1980),
    abrogated by United States v. Quinn, 
    728 F.3d 243
    (3d Cir. 2013) (en banc). Haner acknowledged
    that the Smith approach had been “uniformly rejected by other federal circuit courts, as well as
    numerous state courts, that have addressed judicial use immunity.” 
    2007 VT 49
    , ¶ 9 (citing 
    Smith, 615 F.2d at 974
    ). Because the facts of that case did not support application of such immunity, even
    assuming the Court adopted Smith, we declined to reach the question of “whether the Smith
    approach to judicial immunity is a sound one.” Id.; see also State v. Hamlin, 
    146 Vt. 97
    , 107-08,
    
    499 A.2d 45
    , 52-53 (1985) (declining to decide whether to adopt holding of Smith because Smith
    factors were not satisfied in any event).
    ¶ 26.   Defendant now asks us to consider the question we did not reach in Haner: whether
    the court may extend immunity, without a request by the State, to a third-party witness who invokes
    the right against self-incrimination. We reject defendant’s invitation to adopt Smith’s holding that
    a court may do so in extraordinary circumstances. In so doing, we rely on the overwhelming weight
    of authority, including the Third Circuit’s own abrogation of Smith’s judicial -immunity
    framework.
    ¶ 27.   In Smith, the Third Circuit held that a court has authority to compel the prosecution
    to extend use immunity to a defense witness in certain circumstances, and also described what it
    viewed as a court’s inherent power to grant immunity to a witness where that witness will provide
    crucial exculpatory 
    evidence. 615 F.2d at 969
    . The court identified two differences between such
    “judicial” immunity and an order compelling the prosecution to choose between granting immunity
    or facing dismissal of the charge as a response to prosecutorial misconduct. 
    Id. at 968-69.
    “First,
    the need for ‘judicial’ immunity is triggered, not by prosecutorial misconduct or intentional
    distortion of the trial process, but by the fact that the defendant is prevented from presenting
    9
    exculpatory evidence which is crucial to [the defendant’s] case.” 
    Id. at 969.
    Second, “judicial”
    immunity is not achieved by any order requiring the prosecutor to provide statutory immunity. 
    Id. ¶ 28.
      Smith laid out a five-part test for determining when the trial courts’ ability to confer
    immunity was triggered, bearing in mind that the fundamental requirements of separation of powers
    necessitated that this extension of authority to the judiciary be subject to special conditions. 
    Id. at 971.
    It required that, before a court could grant immunity to a defense witness, (1) the immunity
    must be properly sought in the trial court; (2) the witness must be available to testify; (3) the
    proffered testimony must be clearly exculpatory; (4) the testimony must be essential to the defense;
    and (5) there must be no strong countervailing governmental interest against the grant of immunity.
    
    Id. at 972.
    When these conditions were satisfied, Smith held that a trial court had the authority to
    confer immunity on that witness. 
    Id. at 973-74.
    ¶ 29.   Every other circuit has rejected this approach. See United States v. Serrano, 
    406 F.3d 1208
    , 1217 (10th Cir. 2005) (“Every other Circuit, save the Third, has . . . held a district court
    does not have the inherent authority to grant a defense witness use immunity.”); accord United
    States v. Hunter, 
    672 F.2d 815
    , 818 (10th Cir. 1982) (concluding “that courts have no power to
    independently fashion witness use immunity under the guise of due process”), overruled on other
    grounds by United States v. Call, 
    129 F.3d 1402
    , 1404 & n.2 (10th Cir. 1997); United States v.
    Thevis, 
    665 F.2d 616
    , 639-40 (5th Cir. 1982) (stating that immunity issue involves balancing of
    public interests that should be left to executive branch), superseded by rule as stated in United States
    v. Nelson, 242 F. App’x 164, 171 (5th Cir. 2007).
    ¶ 30.   Eventually, the Third Circuit joined the other circuits in holding that “only the
    Government has statutory authority to seek immunity.” 
    Quinn, 728 F.3d at 255
    . Quinn reasoned
    that Congress assigned exclusive authority to grant immunity to the executive branch “because
    immunity is a prosecutorial tool.” 
    Id. at 253.
    The reasons to leave immunity decisions to the
    executive branch include that “the decision to grant or deny immunity impinges on the
    10
    Government’s broad discretion as to whom to prosecute.” 
    Id. (quotation omitted).
    Because the
    government bears a heavy burden in a subsequent prosecution of proving that its evidence against
    an immunized witness was not obtained or derived from the immunized testimony, a court’s grant
    of immunity to a witness may prevent the Government from ever prosecuting the witness for the
    criminal behavior at issue. 
    Id. at 253-54.
    Prosecutors are in a better position than courts to evaluate
    such tradeoffs, as they can assess the strength of the case, its general deterrence value, and how it
    fits into the government’s enforcement priorities and overall enforcement plan.            
    Id. at 254.
    Significantly, the court also concluded that judicially crafted immunity as set forth in Smith was
    not necessary to protect the constitutional rights of the accused. 
    Id. at 257.
    The court reasoned that
    doctrines proscribing prosecutorial misconduct and allowing courts to put prosecutors to a choice
    between immunizing a witness or having charges against a defendant dismissed can provide the
    necessary protection. 
    Id. ¶ 31.
       We are persuaded by the reasoning of Quinn and other courts that have rejected the
    judicial-immunity construct, and decline to adopt Smith’s holding that a court has inherent authority
    to confer immunity on a witness in this context.
    B. Compelled Statutory Immunity
    ¶ 32.    Defendant next argues that, even if the court’s refusal to grant judicial immunity to
    Edwards was correct, it nonetheless erred by not compelling the State to grant him immunity.
    Defendant submits that the State engaged in misconduct when it threatened to bring escape charges
    against Edwards if he testified he was with defendant on the night in question and the State’s interest
    in refusing to grant immunity to Edwards must give way to defendant’s right to present eyewitness
    testimony. We conclude that defendant has failed to demonstrate that either basis provides grounds
    to compel the State to grant immunity to his witness.
    ¶ 33.   Defendants seeking to compel the State to grant immunity rely on the due process
    right to a fundamentally fair trial, which stems from both the Sixth Amendment and the Due
    11
    Process Clause of the U.S. Constitution. In general, “a defendant has no Sixth Amendment right
    to the testimony of a potential witness who has invoked the Fifth Amendment right against self-
    incrimination; therefore, the defendant has no Sixth Amendment right that could outweigh the
    Government’s interest in using its immunity power sparingly.” United States v. Moussaoui, 
    382 F.3d 453
    , 468 (4th Cir. 2004); United States v. Turkish, 
    623 F.2d 769
    , 773-74 (2d Cir. 1980) (“The
    established content of the Sixth Amendment does not support a claim for defense witness
    immunity. Traditionally, the Sixth Amendment’s Compulsory Process Clause gives the defendant
    the right to bring his witness to court and have the witness’s non-privileged testimony heard, but
    does not carry with it the additional right to displace a proper claim of privilege, including the
    privilege against self-incrimination.”). When, however, the prosecution prevents a defendant from
    putting on exculpatory testimony, impairing a defendant’s ability to present a defense, this can
    violate a defendant’s right to due process. 
    Quinn, 728 F.3d at 261-62
    . Therefore, when necessary
    to prevent a violation of due process, the court may properly put the prosecution to a choice of
    either granting immunity to a defense witness or facing dismissal of the charge. See United States
    v. Burke, 
    425 F.3d 400
    , 411 (7th Cir. 2005) (holding that while “court cannot order the government
    to immunize a defense witness, courts can dismiss an indictment where the prosecutor’s refusal to
    grant immunity has violated the defendant’s right to due process”); 
    Moussaoui, 382 F.3d at 467
    (noting that “[t]he Fourth Circuit, consistent with the majority rule, has held that a district court
    may compel the government to grant immunity upon a showing of prosecutorial misconduct and
    materiality”).
    ¶ 34.     Although courts have generally rejected judicial immunity, many have embraced
    “the carrot-and-stick approach,” under which the decision of whether to grant a witness immunity
    is left with the executive branch but the judiciary reserves the power to force the prosecution to
    choose between certain actions. Carter v. United States, 
    684 A.2d 331
    , 341 (D.C. 1996) (en banc)
    (quotation marks omitted). Essentially, courts threaten dismissal unless the prosecutor requests
    12
    immunity. Courts use different tests to determine when this remedy is warranted. Regardless of
    the test adopted, courts emphasize that this is an area of the law “requiring sensitivity,” and that
    “absent a strong showing by the defense,” courts should be hesitant to find that the State committed
    misconduct in denying immunity to a witness. 
    Quinn, 728 F.3d at 260
    ; see Blissett v. Lefevre, 
    924 F.2d 434
    , 441 (2d Cir. 1991) (emphasizing that courts should order immunity only in “extraordinary
    circumstances”). Not only are courts hesitant to interfere in a prosecutor’s decision of whom to
    prosecute, but courts are cognizant of the need to “reduce the possibility of cooperative perjury
    between the defendant and his witness.” 
    Blissett, 924 F.2d at 442
    .
    ¶ 35.   There are generally two kinds of tests used: the deliberate-distortion test and the
    effective-defense theory. Under the former, courts focus on whether the government deliberately
    distorted the factfinding process by interfering with an important defense witness’s free choice to
    testify. The Second, Fourth, and Ninth Circuits have developed tests that are, to some degree,
    hybrids of the deliberate-distortion test because they require a showing of prosecutorial
    overreaching or discriminatory immunization, and of the testimony’s importance. See, e.g., United
    States v. Straub, 
    538 F.3d 1147
    , 1162 (9th Cir. 2008) (requiring that “for a defendant to compel use
    immunity the defendant must show that: (1) the defense witness’s testimony was relevant; and (2)
    either (a) the prosecution intentionally caused the defense witness to invoke the Fifth Amendment
    right against self-incrimination with the purpose of distorting the fact-finding process; or (b) the
    prosecution granted immunity to a government witness in order to obtain that witness’s testimony,
    but denied immunity to a defense witness whose testimony would have directly contradicted that
    of the government witness, with the effect of so distorting the fact-finding process that the defendant
    was denied his due process right to a fundamentally fair trial”).
    ¶ 36.   The Third Circuit in Quinn also articulated a test that aims to determine when the
    prosecution has abridged the defendant’s right to due process by improperly interfering with the
    defendant’s ability to put on important testimony, even in the absence of obvious witness
    13
    intimidation or discriminatory immunization of witnesses. Some courts refer to this test as the
    effective-defense theory. See State v. Collymore, 
    148 A.3d 1059
    , 1075-76 (Conn. App. Ct. 2016),
    aff’d, __ A.3d __, 
    334 Conn. 431
    (2020) (explaining that under “effective defense theory” immunity
    can be granted when court finds that “potential defense witness can offer testimony which is clearly
    exculpatory and essential to the defense case and when the government has no strong interest in
    withholding immunity” (quotation and alteration omitted)).
    ¶ 37.   It is not necessary to decide in this case whether to adopt one of these tests because
    defendant has failed to meet the requirements of either test. There is no indication that the
    prosecutor’s actions caused defendant’s witness not to testify. Moreover, defendant has not
    demonstrated that the proffered testimony was clearly exculpatory.
    i. Deliberate-Distortion Test
    ¶ 38.   Even if prosecutorial misconduct that deliberately distorts the factfinding process
    could warrant forcing the State to elect between immunization of an important defense witness or
    dismissal, defendant has not demonstrated the necessary causal link in this case.
    ¶ 39.   Defendant claims that the State improperly threatened to charge Edwards with a
    crime and dissuaded Edwards from testifying. Defendant asserts that the State’s threat of charging
    Edwards with escape was based on a false understanding of the law because Edwards could not
    have been charged with felony escape where he was out of place for only a few hours. See 13
    V.S.A. § 1501 (delineating terms of escape from custody).
    ¶ 40.   Prosecutorial misconduct can include intimidation or threats designed to dissuade a
    witness from testifying or selectively immunizing prosecution witnesses to gain a tactical
    advantage. See United States v. Morrison, 
    535 F.2d 223
    , 229 (3d Cir. 1976) (holding that due
    process may require government to grant immunity “when prosecutorial misconduct caused the
    defendant’s principal witness to withhold out of fear of self-incrimination testimony which would
    otherwise allegedly have been available to the defendant”). The defendant must, however, show a
    14
    “causal nexus” between the government’s actions and the witness’s decision not to testify to
    establish a due process violation. United States v. Angiulo, 
    897 F.2d 1169
    , 1193 (1st Cir. 1990);
    see People v. Stewart, 
    93 P.3d 271
    , 304 (Cal. 2004) (explaining that to demonstrate interference
    with right to compulsory process, defendant must show “causal link” between prosecution
    intimidation and witness’s refusal to testify (quotation omitted)).
    ¶ 41.   The evidence fails to demonstrate that the State’s action threatened or intimidated
    Edwards into not testifying.3 Although the State indicated, in the presence of Edwards’s lawyer,
    that it would charge Edwards on the basis of his proffered testimony, the record does not support
    that this interchange led Edwards to invoke his right against self-incrimination. At the time of the
    prosecutor’s remarks, Edwards’s counsel had already informed the court that Edwards would
    invoke his right against self-incrimination if he testified. Before Edwards’s lawyer said he would
    invoke the privilege, the prosecutor had said only, “It is our belief that either Mr. Edwards is going
    to admit to an escape, or Mr. Edwards is going to be perjuring himself. And if that’s what we expect
    him to say, I think the Court should provide him with legal counsel prior to testifying.” Neither
    Edwards nor the lawyer who was subsequently appointed to represent him were present for that
    remark, and moreover, the prosecutor’s remark was appropriate; it seemed calculated to ensure only
    that Edwards had counsel to help him weigh his choice to testify, not to prevent him from testifying.
    3
    Moreover, we reject defendant’s inference that Edwards did not have a basis to claim a
    privilege against self-incrimination because his actions did not amount to a crime. The privilege
    is “confined to instances where the witness has reasonable cause to apprehend danger from a direct
    answer.” Hoffman v. United States, 
    341 U.S. 479
    , 486 (1951). It is not necessary for the
    prospective witness to demonstrate that a prosecution will follow or that answers to questions will
    result in conviction. In re Hill, 
    149 Vt. 431
    , 435, 
    545 A.2d 1019
    , 1022 (1988) (per curiam).
    Moreover, “the trial judge should not speculate about or predict the likelihood of prosecution in
    relation to an assertion of the constitutional privilege against self-incrimination.” Carter v. United
    States, 
    684 A.2d 331
    , 336 (D.C. 1996) (en banc) (indicating majority rule and citing cases). A
    trial court “may only assess the possibility of future prosecution not the probability.” 
    Id. at 337.
    Here, the trial court explained that Edwards was justified in enforcing his privilege because there
    were sufficient facts to indicate that he could be exposed to possible criminal charges. There is no
    indication that the court erred in so finding.
    15
    See L. Wenger, Annotation, Admonitions Against Perjury or Threats To Prosecute Potential
    Defense Witness, Inducing Refusal To Testify, as Prejudicial Error, 
    88 A.L.R. 4th 388
    , § 2(a) (1991)
    (explaining that “[m]any courts have held that it is proper for a prosecutor or trial judge . . . to advise
    the witness of [the] constitutional right to counsel and privilege against self-incrimination” so long
    as it is not “calculated to dissuade the witness from testifying or to intimidate the witness” and is
    not “unnecessary since the witness had already been warned or was going to be warned by other
    means” (footnote omitted)). We conclude that the prosecutor’s statements were not the cause of
    Edwards’s invocation of his right against self-incrimination, and therefore reject defendant’s
    argument that the State violated his right to due process on this ground.
    ii. Effective-Defense or Quinn Test
    ¶ 42.    Moreover, we conclude that even under the Quinn test, defendant has failed to
    demonstrate that his witness was entitled to immunity.             Quinn holds that a defendant can
    demonstrate a need to compel immunity for a witness by showing: (1) immunity was properly
    sought in the trial court; (2) the defense witness was available to testify; (3) the proffered testimony
    was clearly exculpatory; (4) the testimony was essential; and (5) there was no strong governmental
    interest countervailing against a grant of 
    immunity. 728 F.3d at 261-62
    . Here, defendant has not
    met the burden of showing that the proffered testimony was clearly exculpatory.
    ¶ 43.   To demonstrate that a witness’s testimony is clearly exculpatory, defendant must
    show “that it would exonerate or free him of guilt or blame.” 
    Id. at 262.
    This is a high standard
    that demands more than simply showing that the evidence contradicts that offered by the State.
    Clearly exculpatory evidence does not include testimony that is “at best speculative, severely
    impeached by the witness’s prior inconsistent statement(s), ambiguous on its face, or even if
    believed, would not in itself exonerate the defendant.” 
    Id. (alternation omitted)
    (citations and
    quotation omitted). Further, “defense evidence that is overwhelmingly undercut or undermined
    by substantial prosecution evidence in the record becomes so lacking in credibility that it cannot
    16
    be clearly exculpatory.” 
    Id. at 263.
    It is defendant’s burden to “convince[] the court that the
    testimony is both clearly exculpatory and essential.” State v. Simpson, 
    587 N.W.2d 770
    , 772
    (Iowa 1998); see 
    Quinn, 728 F.3d at 262
    (explaining that “defendant must show” five elements,
    including that testimony is “clearly exculpatory”); 
    Carter, 684 A.2d at 344
    (reciting that “defendant
    must first establish to the trial court’s satisfaction that the proposed testimony is (a) material, (b)
    clearly exculpatory, (c) non-cumulative, and (d) unobtainable from any other source”).
    ¶ 44.   Defendant has not satisfied his burden of showing that Edwards’s testimony was
    clearly exculpatory because the proffered testimony was vague, overly speculative, and lacking in
    credibility. Defendant asserts that his attorney “explained in detail why Mr. Edwards’ eyewitness
    testimony would be exculpatory for [defendant],” but no such specificity is provided in the record.
    Defendant made a very general proffer of what Edwards would say if he testified. Defendant
    offered that Edwards would testify that he was walking along the road, that defendant met him by
    chance on the way between the hospital and the baseball field, and that Edwards and defendant
    then went jointly to the baseball field where they discovered the complainant. Defense counsel
    proffered that Edwards would “testify that all of the things that [complainant] says are not true, or
    he’ll testify to events that are different to the events that [complainant] testified, to an extent that
    both versions cannot be true.”
    ¶ 45.   This proffer was too vague and nonspecific to conclude that Edwards’s testimony
    would have been clearly exculpatory, especially as to the single count for which defendant was
    convicted.4 See United States v. Triumph Capital Grp., Inc., 237 F. App’x 625, 630 (2d Cir. 2007)
    (concluding that defendant’s speculation regarding how witnesses would have testified was “not
    sufficient to prove that their testimony would have been exculpatory”). The assault charge was
    based on the specific allegation that defendant had burned complainant with a cigarette.
    4
    We need not consider whether the proffer established clearly exculpatory evidence
    regarding the other counts because defendant was acquitted of those charges.
    17
    Complainant testified that after defendant found her at the baseball field, there was a physical
    altercation between them, both were screaming, and defendant promised to help her, so she got
    into the front seat of the car. She stated that they were yelling at each other in the car and defendant
    became so angry with complainant that he took a lit cigarette and put it out on her chest. She
    screamed loudly due to the pain this caused. There was other evidence at trial corroborating
    complainant’s injury, including from a police officer, who testified that complainant had a cigarette
    burn on her chest later that evening.
    ¶ 46.   Defendant’s version of events differed dramatically. He testified that he picked up
    Edwards prior to going to the baseball field and that Edwards climbed into the backseat of the
    vehicle. After complainant got into the car, defendant stated that Edwards was sitting behind
    complainant. When asked about complainant’s burn, defendant testified that he observed a burn
    on the complainant’s chest but did not ask her about it.
    ¶ 47.   As to this series of events, defendant’s proffer does not lend any helpful indication
    of how Edwards’s testimony would be exculpatory. Defendant’s proffer did not specify what
    Edwards would say regarding defendant’s actions inside the car and specifically as to the cigarette
    burn. Defendant claimed that Edwards would contradict everything that complainant said but it is
    not clear how Edwards could have seen whether defendant put the cigarette out on complainant’s
    chest when defendant himself testified that Edwards was sitting directly behind complainant in the
    car. Defendant claimed in his testimony that he did not know how complainant got the cigarette
    burn. If Edwards testified similarly, this would not directly contradict complainant’s testimony.
    Without more specificity as to what Edwards saw or heard in the car, there was no ability to
    evaluate the extent to which Edwards could exonerate defendant or to evaluate the consistencies
    or inconsistencies between Edwards’s version and defendant’s or complainant’s.
    ¶ 48.   In deciding whether testimony is clearly exculpatory, “the court may evaluate the
    credibility of the proffered evidence, and is not required to simply take it at face value.” Haner,
    18
    
    2007 VT 49
    , ¶ 10. In Haner, we examined the prospective testimony of the defendant’s witness
    and concluded it lacked credibility because it was made by someone with a close familial
    relationship to the defendant, was made several years after the defendant’s conviction, and
    contained several inconsistencies with the testimony from other witnesses. 
    Id. ¶¶ 11-13.
    ¶ 49.   Here, the vague proffer of Edwards’s testimony impairs evaluating its credibility.
    Because there were no specifics offered regarding what Edwards allegedly saw or heard from the
    backseat, there is no practical way to evaluate whether Edwards’s testimony would have
    contradicted or corroborated the testimony of other witnesses. To the extent that the credibility of
    Edwards’s testimony can be evaluated, his testimony is undermined by the context in which it
    arose and by the other evidence. See People v. Hull, 
    243 Cal. Rptr. 3d 375
    , 395 (Ct. App. 2019)
    (stating that evidence is not clearly exculpatory if it is “ ‘overwhelmingly undercut or undermined
    by substantial prosecution evidence’ ” (quoting 
    Quinn, 728 F.3d at 263
    )), review denied (May 1,
    2019). The context of Edwards’s corroboration of defendant’s version of events is suspect because
    Edwards did not come forward until a couple of weeks before trial and defendant testified that
    Edwards was his close friend. Moreover, other evidence undercuts Edwards’s claim. Another
    defense witness testified that when she spoke with defendant on the telephone that evening (during
    the time when defendant claimed Edwards was with him), defendant said that it was just him and
    complainant in the car. In addition, the State produced evidence that Edwards’s ankle monitor
    showed that he was at a different location that evening. Given the vague proffer and the other
    indicia of lack of credibility, defendant did not meet his burden of showing that his witness’s
    testimony would be clearly exculpatory.
    19
    ¶ 50.   Because we conclude that defendant failed to meet this criterion, we need not reach
    the question of whether the evidence was essential and noncumulative.5 We note, however, that
    the record tends to indicate that the testimony was not essential because it was otherwise available.
    During the parties’ discussions in the trial court, the State indicated that it had deposed Edwards
    on August 3. The parties made some general statements about the content of the deposition
    testimony but there is no indication in the record of what exactly Edwards said during his
    deposition and if this deposition could have provided an alternative to granting Edwards immunity.
    A witness who has asserted a Fifth Amendment privilege is unavailable to testify for purposes of
    Vermont Rule of Evidence 804(a)(2). State v. Roberts, 
    154 Vt. 59
    , 66-67, 
    574 A.2d 1248
    , 1251
    (1990). When a witness is not available, deposition testimony may be admitted if it bears certain
    indicia of reliability. 
    Id. It was
    defendant’s burden to demonstrate that Edwards’s testimony was
    clearly exculpatory, essential, and not cumulative. Therefore, the lack of information as to this
    factor operates against defendant.
    ¶ 51.   Even if the testimony is exculpatory, essential, and noncumulative, the court may
    deny a request to compel immunizing a defense witness if there is a strong governmental
    countervailing interest. These reasons include when there is a clear indication of potential perjury
    or where the grant of immunity may impact future prosecution. Hayes v. United States, 
    109 A.3d 1110
    , 1117 (D.C. 2015). In this case, the State based its denial of immunity for Edwards in part
    on its assessment that there was a clear indication of potential perjury given the evidence that GPS
    data showed Edwards was not in the location he alleged on that night. We need not reach the
    question of whether the State had a strong countervailing interest for refusing to grant immunity
    5
    Some courts have held that where a witness simply corroborates the testimony of the
    defendant, it is cumulative and does not require a grant of immunity. See, e.g., State v. Dixon, 
    716 S.W.2d 815
    , 818 (Mo. Ct. App. 1986). We need not reach this question.
    20
    to Edwards because we conclude that defendant did not meet his burden of showing that the
    testimony was clearly exculpatory.
    II. Supplemental Instruction
    ¶ 52.    Defendant next contends that the jury was improperly coerced into reaching a
    verdict. He argues that the court’s supplemental instruction implied that jurors had such a strong
    duty to reach a verdict that some should compromise their convictions to do so and suggested the
    minority should yield to the majority. See State v. Perry, 
    131 Vt. 337
    , 340, 
    306 A.2d 110
    , 112
    (1973) (explaining attributes of impermissible supplemental charge).              He argues that the
    circumstances of this case were such that we should conclude that the jurors were impermissibly
    pressured into coming to a verdict. We do not agree that the court improperly coerced the jury.
    ¶ 53.    After closing arguments, the trial court instructed jurors to “not surrender your
    honest belief as to the weight or fact of the evidence, solely because of the opinions of your fellow
    jurors or for the mere purpose of returning a verdict.” The jury then retired. It deliberated for
    several hours and reached a verdict on three out of the four charges but was unable to reach
    agreement on count one, the domestic-assault charge. Immediately prior to calling in the jurors,
    the court stated that it would issue a “so-called Allen charge” to encourage them to reach a verdict
    on the final issue.6
    ¶ 54.    The court stated:
    [W]ith respect to Count I—I know it’s late, it’s 8:20 in the evening,
    it’s been a very long day, but I’m duty bound to ask you to try one
    more time to see if you can talk through and work through whatever
    differences you may have with regard to Count I. As you’ve seen
    over the last two days, a lot of time and effort has gone into this
    process to get to this point. There’s no guarantee that even if we
    were to do it all over again, that the evidence would come in any
    more clearly than it has—or not so clearly as it has during this trial.
    Every trial is an entity unto itself with unforeseen circumstances that
    arise, so there’s no guarantee that the next time would make it any
    easier for a second jury. And another jury of twelve, fair-minded,
    6
    This description comes from the case Allen v. United States, 
    164 U.S. 492
    , 501 (1896).
    21
    reasonable people like yourselves could easily struggle just as much
    with a decision as to Count I as you have, apparently, so far this
    evening. So I’m going to ask you to return to the jury room, and
    give it one more try to see if you can work through your differences
    and come to a unanimous verdict, whatever that may be, with regard
    to Count I. And if you’ve given a good-faith attempt at that, and
    you’re still unable to reach a unanimous decision, then let the court
    officer know, and we’ll proceed accordingly.
    Forty-five minutes later, the jury reached a guilty verdict on the charge of domestic assault.
    ¶ 55.   Defendant did not object either when the trial court said it would issue the “so-
    called Allen charge” or after delivery of the supplemental instruction.         He challenged the
    instruction for the first time in a post-trial motion. Under Vermont Rule of Criminal Procedure
    30, “[n]o party may assign as error any portion of the charge or omission therefrom unless the
    party objects thereto on the record either at a charge conference or before the jury retires to
    consider its verdict.” V.R.Cr.P. 30(b). Because defendant made no such objection, we review the
    jury instruction for plain error. State v. Carter, 
    2017 VT 32
    , ¶ 6, 
    204 Vt. 383
    , 
    169 A.3d 225
    (“Where there has been no objection to the instruction in the trial court as required by Vermont
    Rule of Criminal Procedure Rule 30, we review only for plain error.”).
    ¶ 56.   The instruction in this case was not error, let alone plain error. “Defendant bears
    the burden of presenting facts sufficient to support his claim that the verdict was coerced.” State
    v. Pratt, 
    2015 VT 89
    , ¶ 36, 
    200 Vt. 64
    , 
    128 A.3d 883
    . This Court evaluates jury instructions in
    their full context. State v. Bolaski, 
    2014 VT 36
    , ¶ 19, 
    196 Vt. 277
    , 
    95 A.3d 460
    (“We review jury
    instructions as a whole to ensure that they convey the spirit of the law and there is no fair ground
    to say that the jury was misled.”); 
    Perry, 131 Vt. at 340
    , 306 A.2d at 112 (holding that whether
    reversible error “can be predicated on the use of [an Allen] charge must be tested by the
    circumstances”). The full context here—including the supplemental charge, which did not possess
    the troublesome attributes of an Allen charge, the original jury instruction, which admonished the
    22
    jurors not to surrender their honest beliefs, and the timing of the verdict—does not support
    defendant’s claim that the jury was impermissibly pressured or coerced.
    ¶ 57.   The instruction here did not have the shortcomings of a true Allen charge. In Allen
    v. United States, the U.S. Supreme Court approved a charge that, as we noted in Perry, other courts
    and commentators have since widely 
    condemned. 131 Vt. at 339-40
    , 306 A.2d at 112 (citing Allen
    v. United States, 
    164 U.S. 492
    (1896)). In Allen, the judge gave the jury a supplemental charge
    that admonished them, among other things, “that it was their duty to decide the case if they could
    conscientiously do so” and “that, if much the larger number were for conviction, a dissenting juror
    should consider whether his doubt was a reasonable one which made no impression upon the minds
    of so many men, equally honest, equally intelligent with himself,” and “[i]f, upon the other hand,
    the majority were for acquittal, the minority ought to ask themselves whether they might not
    reasonably doubt the correctness of a judgment which was not concurred in by the majority.”
    
    Allen, 164 U.S. at 501
    . As Perry notes, an Allen charge suffers from two interrelated ills. First, it
    seems to make jurors’ duty to reach a verdict so strong an obligation that they must compromise
    their convictions to do so. 131 Vt. at 
    340, 306 A.2d at 112
    . Second,
    it similarly lays a burden on the minority of a divided jury not only
    to reexamine their position, which is proper, but seemingly to yield
    those convictions produced in them by the facts, when the same facts
    bring the majority to an opposite result. Missing is a balanced
    appeal to the majority to reexamine the validity of their position, and
    an injunction not to abandon honest convictions merely to reach a
    verdict.
    
    Id. ¶ 58.
      The supplemental charge here did not emphasize the jurors’ duty to reach a verdict,
    let alone urge the jurors to sacrifice their convictions to do so. In fact, the instruction reassured
    the jurors that, if they were unable to work through their differences, they could let the court officer
    know and they would “proceed accordingly.” Moreover, the charge did not single out the minority
    23
    jurors and pressure them to reconsider their position. Instead, the instructions asked all jurors to
    “give it one more try to see if you can work through your differences.”
    ¶ 59.   Although defendant cites Perry in support of his challenge, the Perry charge was
    similar to the one provided here, and we upheld the charge in that case. 
    Id. at 341,
    306 A.2d at
    112-13. In Perry, after deliberating for several hours, the jury informed the court it was having
    problems. The court “interrupted, and reminded the jurors that a failure to reach a verdict brings
    about a mistrial, which puts the respondent and the state to the burden of a retrial, with no assurance
    that any other jury could do any better.” 
    Id. at 339,
    306 A.2d at 111-12. The court then asked the
    jury “to deliberate another half hour to see if they could arrive at a verdict on either or both of the
    charges.” 
    Id. at 339,
    306 A.2d at 112. We held that the instruction
    was not the Allen charge. It did not urge, in any way, the convictions
    be abandoned, or honestly held positions be accommodated, for
    verdict purposes. It merely called to the jury’s view the undeniable
    fact that the responsibility of decision in this case is theirs, and of
    great importance to the parties, and justified their best efforts to
    avoid a failure to resolve the issues, if that was morally possible.
    This concern has been previously recognized as proper in our law.
    Id. at 
    340, 306 A.2d at 112
    .
    ¶ 60.   The court’s reminders in this case that “a lot of time and effort had gone into this
    process to get to this point” and another jury might similarly struggle with the case were proper,
    like the reminder in Perry to use “their best efforts to avoid a failure.” 
    Id. Although the
    charge
    here did not contain the “injunction not to abandon honest convictions merely to reach a verdict,”
    
    id., which is
    desirable, neither did the charge we upheld in Perry. In both cases, such a reminder—
    while it would have been best practice—was not critical because nothing the court said implied
    that any jurors should abandon honest convictions.
    ¶ 61.   The surrounding context also does not indicate that the jury instruction had a
    coercive effect. 
    Id. The trial
    court’s initial instructions directed that jurors should not abandon
    their honestly held beliefs to reach a verdict, and further instructions did not contradict this. The
    24
    short duration of time between the supplemental instruction and the jury’s final verdict does not
    demonstrate the jury was coerced. If a jury returns a verdict shortly following a potentially
    coercive charge, that could demonstrate the charge’s coercive effect. See Lowenfield v. Phelps,
    
    484 U.S. 231
    , 240 (1988) (“We are mindful that the jury returned with its verdict soon after
    receiving the supplemental instruction, and that this suggests the possibility of coercion.”). Here,
    the trial court had instructed the jury in its initial charge to “take the time you feel is necessary to
    pass upon all the issues in the case and give it the consideration its gravity and importance
    deserve.” After several hours of initial deliberations, forty-five minutes of additional deliberation
    is not so brief as to suggest that the supplemental charge had a coercive effect.
    Affirmed.
    FOR THE COURT:
    Associate Justice
    ¶ 62.   ROBINSON, J., dissenting.          Because I conclude the trial court should have
    compelled the State to either grant immunity or face a judgment of acquittal, I respectfully dissent.7
    I believe the Third Circuit’s Quinn test best serves the purpose of compelled statutory immunity,
    and applying that test to the facts of this case, I conclude that defendant made a sufficient showing.
    I. The Quinn Test
    ¶ 63.   Whatever test this Court ultimately adopts for compelled statutory immunity must
    serve the competing values that shape its use. Courts have taken divergent approaches to
    determining when to impose compelled statutory immunity. For reasons set forth more fully
    below, I would adopt the test laid out by the Third Circuit in United States v. Quinn as the most
    7
    I agree with the majority that the trial court properly declined to extend “judicial
    immunity” to defendant’s witness in this case, and join in the majority’s analysis of the trial court’s
    charge urging the jury to keep deliberating.
    25
    developed example of a framework that balances the State’s legitimate prosecutorial needs and a
    defendant’s interest in an effective defense. See 
    728 F.3d 243
    (3d Cir. 2013).
    ¶ 64.   Courts generally agree that, in extraordinary situations where necessary to prevent
    a violation of due process, the court may properly put the prosecution to a choice of either granting
    immunity to a defense witness or facing dismissal of the charge. See United States v. Moussaoui,
    
    382 F.3d 453
    , 467 (4th Cir. 2004) (noting that majority rule is that court may compel government
    to grant immunity upon showing of material prosecutorial misconduct).
    ¶ 65.   This compelled statutory immunity is an attempt to balance a number of competing
    constitutional concerns. “ ‘It has long been recognized that the Executive Branch of government
    has exclusive authority and absolute discretion to decide whether to prosecute a case,’ ” and
    therefore, “ ‘[t]o interpret the Fifth and Sixth Amendments as conferring on the defendant the
    power to demand immunity for co-defendants, potential co-defendants, or others whom the
    government might in its discretion wish to prosecute would unacceptably alter the historic role of
    the Executive Branch in criminal prosecutions.’ ” United States v. Straub, 
    538 F.3d 1147
    , 1156
    (9th Cir. 2008) (quoting United States v. Alessio, 
    528 F.2d 1079
    , 1081-82 (9th Cir. 1976)).
    ¶ 66.   But this “ ‘power the government possesses’ ” to decide whom to prosecute, and
    how to prosecute them, “ ‘may not be exercised in a manner which denies the defendant . . . due
    process,’ ” and it is the court’s role to ensure due process. 
    Id. at 1147,
    1164, 1166 (quoting 
    Alessio, 528 F.2d at 1082
    ) (holding that prosecution’s refusal to immunize sole defense witness who could
    have discredited testimony of immunized prosecution witness distorted factfinding process such
    that defendant was denied fair trial, and reversing conviction). The Fifth Amendment Due Process
    Clause and the Sixth Amendment together “guarantee[] criminal defendants a meaningful
    opportunity to present a complete defense.” Crane v. Kentucky, 
    476 U.S. 683
    , 690 (1986)
    (quotation omitted). Part of this right to a meaningful opportunity to present a complete defense
    is a “right to present witnesses who will testify on [the defendant’s] behalf.” United States v.
    26
    Burke, 
    425 F.3d 400
    , 411 (7th Cir. 2005). The Sixth Amendment right to compulsory process to
    compel witnesses generally gives way when a witness subpoenaed by the defendant invokes the
    privilege against self-incrimination. Diggs v. Owens, 
    833 F.2d 439
    , 444 (3d Cir. 1987). But when
    the prosecution prevents a defendant from putting on exculpatory testimony, impairing the
    defendant’s ability to present a defense, this can violate the defendant’s right to due process.
    
    Quinn, 728 F.3d at 261-62
    .
    ¶ 67.   In such situations, the court may need to intervene to protect the defendant’s right
    to due process. See 
    id. at 252-53.
    In doing so, the court cannot directly order the government to
    immunize a defense witness, but can dismiss an indictment where a prosecutor’s refusal to grant
    immunity violates defendant’s due process rights. See 
    Burke, 425 F.3d at 411
    . This respects the
    separation of powers: while it is the State’s role to decide whom to prosecute and how to prosecute
    them, it is the court’s role to safeguard defendants’ constitutional rights. Dismissing the charges
    unless the witness is immunized is within the court’s powers to ensure due process. And it
    ultimately “leaves prosecutorial decisions in the hands of the Government.” 
    Quinn, 728 F.3d at 260
    .
    [The State] may grant immunity to the witness and attempt to
    convict the defendant in a fair trial, or it may decide that denying the
    witness immunity is more important to its goals than seeking that
    conviction. But the remedy does not compel the Government to do
    anything. It simply prevents prosecutors from obtaining a
    conviction through a process that lacks the fairness afforded by due
    process.
    Id.; see also 
    Burke, 425 F.3d at 411
    (“The prosecutor’s broad discretion to refuse immunity is
    limited by the defendant’s due process rights.”).
    ¶ 68.   As the majority notes, courts have adopted two types of tests—the “deliberate-
    distortion” test that focuses on whether the government deliberately distorted the factfinding
    process by interfering with an important defense witness’s free choice to testify, and the “effective-
    27
    defense” test that balances the prosecution’s legitimate needs against the effect of the denial of
    immunity on a defendant’s ability to mount a defense. Ante, ¶¶ 35-36.
    ¶ 69.   Courts that apply a “deliberate-distortion” test focus on the subjective intentions of
    prosecutors. See, e.g., State v. Feaster, 
    877 A.2d 229
    , 239, 247 (N.J. 2005) (reversing and
    remanding where state had threatened key prosecution witness to prevent him from recanting in
    post-conviction relief proceeding); United States v. Angiulo, 
    897 F.2d 1169
    , 1192 (1st Cir. 1990)
    (noting that when prosecution “intimidate[s] or harass[es] potential defense witnesses to
    discourage them from testifying—for example, by threatening them with prosecution for perjury
    or other offenses”—and witness consequently refuses to testify, “court may order the prosecutor
    to grant immunity to the witness or face a judgment of acquittal”); United States v. Patterson, 
    819 F.2d 1495
    , 1506 (9th Cir. 1987) (noting that if defendant shows that prosecutors intentionally
    prevented defense witness from giving relevant testimony, “acquittal is required unless
    prosecution requests immunity for the witness at a new trial”); United States v. Morrison, 
    535 F.2d 223
    , 229 (3d Cir. 1976) (granting motion for new trial and ordering that at new trial, if defendant
    calls witness prosecutor previously threatened and witness invokes Fifth Amendment right not to
    testify, court shall enter judgment of acquittal unless government requests use immunity for her
    testimony).8
    ¶ 70.   In Quinn, the Third Circuit adopted an alternative test that considers the impact on
    a defendant’s right to a fair trial and the government’s 
    interests. 728 F.3d at 261-62
    . In particular,
    that court has established a multifactorial test under which: “(1) Immunity must be properly sought
    in the district court; (2) the defense witness must be available to testify; (3) the proffered testimony
    must be clearly exculpatory; (4) the testimony must be essential; and (5) there must be no strong
    8
    Several courts have adopted hybrid versions of the “deliberate-distortion” test pursuant
    to which some nondeliberate acts such as selective grants of immunity may also support an order
    for compelled statutory immunity. See, e.g., United States v. Wilkes, 
    744 F.3d 1101
    , 1104-05 (9th
    Cir. 2014).
    28
    governmental interests which countervail against a grant of immunity.” 
    Id. (quotation and
    alteration omitted). The Third Circuit “does not require a defendant to show specific intent on the
    part of the Government to interfere with [the defendant’s] due process rights” because the central
    “concern is with the effect of the prosecutor’s actions on the process afforded to the defendant.”
    
    Id. at 260.
    ¶ 71.   Other courts have likewise adopted similar tests that do not require proof of
    deliberate distortion by a prosecutor. Arizona requires either proof of prosecutorial misconduct or
    “a showing that the witness would present clearly exculpatory evidence and that the state has no
    strong interest in withholding immunity.” State v. Doody, 
    930 P.2d 440
    , 453 (Ariz. Ct. App.
    1996); see also State v. Martinez, 
    189 P.3d 348
    , 356 (Ariz. 2008) (en banc) (quoting same). The
    District of Columbia requires a showing that “the defendant will not receive a fair trial in the
    absence of the proposed material, exculpatory, non-cumulative, and otherwise unobtainable
    testimony,” and asks whether “the government has not provided a reasonable basis for refusing
    immunity.” Hayes v. United States, 
    109 A.3d 1110
    , 1116 (D.C. 2015).
    ¶ 72.   For several reasons, the Quinn test best promotes the purposes underlying
    compelled statutory immunity. The test is designed to “capture those situations where the
    Government, for tactical reasons, has used its power to threaten prosecution and withhold
    immunity to keep exculpatory and essential testimony from trial for no strong countervailing
    reason.” 
    Quinn, 728 F.3d at 259
    . Because it is difficult to show that a prosecutor’s choice to
    withhold immunity is motivated by a “deliberate” intent to “distort” the facts, the “deliberate-
    distortion” test does not capture this class of cases, even though the impact on a defendant’s ability
    to mount a defense is the same.
    ¶ 73.   The point of compelled statutory immunity is to protect a defendant’s right to a fair
    trial, not to punish prosecutorial overreach. As the Third Circuit reasoned in Quinn, “[t]he Due
    Process Clause addresses the defendant’s right to a fair trial, not just whether the government
    29
    intended to deny the defendant his rights,” and “[c]ourts should protect against deliberate
    wrongdoing by prosecutors and, in those rare cases where it arises, overzealous advocacy that
    distorts the factfinding function of a criminal trial.” 
    Id. at 260
    (quotation omitted). The Ninth
    Circuit has likewise observed, in applying a somewhat different test, “compel[led] use immunity
    is not a sanction for prosecutorial misconduct; it is a vindication of the defendant’s Fifth
    Amendment due process right to a trial in which the fact-finding process has not been distorted.”
    
    Straub, 538 F.3d at 1161
    . “Because compelling use immunity is not a sanction for prosecutorial
    misconduct, it follows that the defendant need not prove that the prosecution acted intentionally to
    distort the fact-finding process where the [test’s] other elements”—in Quinn, the relevance of the
    evidence and the prosecutor’s selective immunization of witnesses that distorted the factfinding
    process—“are met.” 
    Id. This logic
    makes sense.
    ¶ 74.   Moreover, the Quinn test, with its final requirement that there be no strong
    countervailing reason against the grant of immunity, protects the State’s legitimate interests in
    investigating and prosecuting potential defense witnesses for crimes they have committed, and in
    ensuring that subsequent prosecutions are not hamstrung by requirements that the State
    demonstrate it has not made use or derivative use of immunized testimony. For these reasons, the
    test best serves both the needs of the defendant and the State.
    II. Application to this Case
    ¶ 75.   Applying this test to the facts of this case, I conclude that defendant has satisfied
    the requirements of the Quinn test. I agree with the majority that defendant has not shown that the
    State substantially interfered with Edwards’s choice to testify by threatening or intimidating him,
    ante, ¶ 41, but conclude that its refusal to grant Edwards immunity deprived defendant of due
    process.
    ¶ 76.    Defendant has satisfied each element of the Quinn test.          Defendant sought
    immunity for Edwards in the trial court. Edwards was available to testify. The proffered testimony
    30
    was clearly exculpatory,9 and the testimony was essential. And finally, there was no apparent
    strong governmental interest countervailing against a grant of immunity.
    ¶ 77.    With respect to the first element, defendant sought immunity in the trial court. The
    State notes that “[a]lthough [defendant] did not direct his immunity request to the prosecutor, her
    comments made clear that she would have refused to immunize Edwards if counsel had asked her.”
    In general, defendants should ask the prosecution—not the court—for immunity for a defense
    witness. But given the unsettled nature of the law at the time of trial, and the fact that the State
    made it abundantly clear that it was “not . . . agreeable to providing any sort of immunity to Mr.
    Edwards for his testimony,” defendant adequately laid the foundation to request immunity for
    Edwards.
    ¶ 78.    Edwards was available to testify; the trial transcript reflects that he was in the
    courthouse waiting to testify. The State does not contest this point.
    ¶ 79.    The proffered testimony was clearly exculpatory. Testimony is clearly exculpatory
    if “it would exonerate or free [the defendant] of guilt or blame. Testimony that is at best
    speculative, severely impeached by the witness’s prior inconsistent statements, ambiguous on its
    face, or even if believed, would not in itself exonerate the defendant, is not clearly exculpatory.”
    
    Quinn, 728 F.3d at 262
    (quotations and alterations omitted). The defense attorney said:
    Edwards [would] testify that, on July 2nd, 2016, he was walking in
    the vicinity of the intersection of Colchester Avenue and Mansfield
    Avenue, and that Mr. Gates, en route between the hospital and
    Centennial Field, ran into Mr. Edwards, that Mr. Edwards got into
    the vehicle with Mr. Gates, that they together went to Centennial
    Field, where they discovered an unconscious [complainant].
    He said Edwards would testify to being in the car not only at the baseball field, but also at the
    Richmond gas station. He said Edwards would “testify that all of the things that [complainant]
    9
    This point is the crux of my disagreement with the majority.
    31
    says are not true, or he’ll testify to events that are different to the events that [complainant]
    testified, to an extent that both versions cannot be true.”
    ¶ 80.   If Edwards testified as the defense attorney said he would, this testimony would
    have been clearly exculpatory. If Edwards said, as proffered, that he was present in the car from
    the time defendant picked up complainant at the baseball field to the time they parted ways at the
    Richmond gas station, and explained how the events of the night were very different from what
    complainant said happened, that testimony would “exonerate or free [the defendant] of guilt or
    blame.” 
    Quinn, 728 F.3d at 262
    . Although defendant’s proffer did not break the witness’s
    anticipated testimony down statement by statement, the information it did include indicated it
    would be exonerative.10 The proffer does not require substantial inferential leaps. Cf. State v.
    Schreiner, 
    2007 VT 138
    , ¶ 28, 
    183 Vt. 42
    , 
    944 A.2d 250
    (holding, in context of motion for new
    trial on basis of newly discovered evidence, that impact of proffered testimony was too speculative
    where inmate alleged that his cousin made an unspecific threat against an unnamed person in
    victim’s town, but there was no evidence that cousin and victim ever met or that cousin ever went
    to victim’s town). This is not a case in which a defendant is merely speculating about what a
    witness would say if called. It is clear from the record, including the State’s representations, that
    Edwards had been deposed shortly before the trial. Cf. In re Towne, 
    2018 VT 5
    , ¶ 40, 
    206 Vt. 10
               The context of defendant’s “proffer” is significant. Defendant first described Edwards’s
    anticipated testimony not because he was seeking immunity for the witness, but because he was
    seeking an order from the court prohibiting the State from impeaching the witness by referencing
    the witness’s GPS ankle bracelet, which would, in turn, reveal that he was under Department of
    Corrections supervision. That conversation segued into a request from the State to provide
    Edwards counsel before his testimony. Later that morning, after Edwards conferred with counsel
    and, through that lawyer, invoked his Fifth Amendment privilege, defendant first raised the issue
    of immunity. After a break to review the law, the trial court denied the request, ruling, correctly,
    that the court did not have authority to extend to judicial immunity. The court did not address
    whether it could order the State to extend immunity or dismiss the charges, and the substance of
    the proffer (beyond the fact that it would subject the witness to potential jeopardy in connection
    with his furlough status) was not a subject of discussion among the court and parties.
    32
    615, 
    182 A.3d 1149
    (holding, in context of post-conviction-relief petition, that petitioner’s
    assertion that if defense counsel had interviewed specified witnesses they would have confirmed
    his alibi relied on speculation). Even Edwards’s testimony that he had been in the car would have
    been, if not conclusively exonerative, highly valuable testimony for defendant: it would
    corroborate defendant’s version of events and severely undercut complainant’s, because defendant
    testified that Edwards was in the car and complainant did not.
    ¶ 81.   The fact that Edwards’s testimony would have been impeached by a defense
    witness’s testimony and GPS records of Edwards’s ankle monitor does not change my analysis.
    The State essentially argues that the trial court did not err in declining to order the State to grant
    immunity or dismiss the charges because Edwards’s testimony would not have been credible. The
    jury is the “sole judge” of witnesses’ credibility. State v. Robitille, 
    2019 VT 36
    , ¶ 34, __ Vt. __,
    
    213 A.3d 437
    (quotation omitted). As the “purpose of exculpatory evidence is to contradict the
    Government’s evidence against” the defendant, it is “hard to imagine” a case in which a
    defendant’s evidence of innocence is not undermined by the Government’s evidence of guilt.
    
    Quinn, 728 F.3d at 262
    -63. “The existence of conflicting evidence does not affect, however,
    whether the defense evidence is exculpatory, though it may affect its weight.” 
    Id. at 263.
    “We
    have confidence that our courts and juries are capable of detecting falsehoods with the aid of the
    adversarial process,” and thus even where a defense witness’s testimony is called into some doubt,
    “it is not the function of the State to save a defense witness from himself or to spare the court a
    supposed falsehood, at the expense of denying the court critical testimony.” 
    Feaster, 877 A.2d at 244
    .
    ¶ 82.   Of course, the “threat of a blatant perjury may sometimes be so apparent as to be
    demonstrable to the trial judge that the government could not reasonably be expected to cloak in
    advance such testimony with immunity.” Young v. United States, 
    143 A.3d 751
    , 757 (D.C. 2016)
    (alterations and quotation omitted). “Thus, though exculpatory on its own, defense evidence that
    33
    is overwhelmingly undercut or undermined by substantial prosecution evidence in the record
    becomes so lacking in credibility that it cannot be clearly exculpatory.” 
    Quinn, 728 F.3d at 263
    .
    It was for that reason that in State v. Hamlin, 
    146 Vt. 97
    , 107-08, 
    499 A.2d 45
    , 52-53 (1985), this
    Court found “no need to pass on the applicability of” the Smith test in Vermont. See Government
    of Virgin Islands v. Smith, 
    615 F.2d 964
    (3d Cir. 1980). In Hamlin:
    the proposed defense witness had “acknowledged freely and
    repeatedly that he had lied under oath and, even more significantly,
    that he felt lying was acceptable conduct. He admitted to lying
    during his sworn statements and during his depositions. In a
    chambers conference, the trial court summarized the situation: “[he]
    has made statements that are both exculpatory and inculpatory of
    [defendant]. I don’t think there is one person in this room that
    knows what [he] would say if he got on that 
    stand.” 146 Vt. at 107-08
    , 499 A.2d at 52-53 (alteration omitted). Given the witness’s propensity for lying
    and the possibility that his testimony would not be exculpatory at all, we concluded the defendant
    had not shown the testimony would be clearly exculpatory. 
    Id. at 108,
    499 A.2d at 53.
    ¶ 83.   Likewise, we held in State v. Haner that the proffered testimony—the defendant’s
    brother’s confession to the sexual assault for which the defendant was convicted—was not clearly
    exculpatory. 
    2007 VT 49
    , ¶ 13, 
    182 Vt. 7
    , 
    928 A.2d 518
    . There were multiple inconsistencies
    between the brother’s testimony and others’: “throughout the pretrial investigations and trial, not
    a single mention was made of the brother’s potential presence in the trailer at the time of the
    offense”; the “[d]efendant’s son testified that he could not recall defendant’s brother ever sleeping
    in his room[, but] defendant’s brother claimed that he slept there on the night of the assault”; and
    although the victim “testified that she heard her assailant leave her room through a doorway to the
    hall and shortly thereafter saw defendant walk into the room, defendant’s brother claimed that he
    hid at the foot of her bed as defendant entered the room.” 
    Id. ¶ 11.
    Additionally, we noted that
    the circumstances surrounding the confession diminished its credibility:
    Defendant’s brother waited until approximately three years after
    defendant was first accused to come forward with his confession.
    34
    By that time, defendant’s appeal had been taken and denied,
    presenting the opportunity for his brother to tailor his confession to
    the facts and theories already on the record. Furthermore,
    defendant’s brother acknowledged to the police that he was aware
    that, as a juvenile, he would be subject to a lesser punishment than
    defendant. When asked by the police why he waited so long to
    confess, defendant’s brother answered that his sister-in-law “was
    trying to, um, she was the one that was trying to find out what to
    say, not what to say but um, where to go to report it.”

    (citation omitted). And “[f]inally, the familial relationship between defendant and his
    brother call[ed] into question the veracity of any exculpatory statements by defendant’s brother,”
    particularly because a sheriff’s deputy “testified that during a July 2003 hearing she sat behind
    defendant’s brother and two women who appeared to be his aunts. She overheard defendant’s
    brother tell the women: ‘We’ll be all right as long as he doesn’t do it again when he gets out.’ ”
    
    Id. ¶ 13.
    We held, “In light of the increased motive of close relatives to fabricate exculpatory
    evidence, the inconsistencies between the confession and witnesses’ testimony, and the general
    circumstances surrounding the confession, we agree with the trial court that defendant failed to
    make a ‘convincing showing’ that the proffered testimony was ‘clearly exculpatory.’ ”

    4.   In contrast to Hamlin and Haner, where there were clear threats of perjury, here,
    the State represented it had evidence that could impeach Edwards’s statements, but it did not
    clearly establish that Edwards’s testimony would be perjury. A defense witness testified that she
    spoke to defendant on the phone sometime around 9:00 and 11:00 on the night of July 2, 2016,
    and that during the call he said it was just complainant in the car. Furthermore, counsel represented
    at trial that GPS records showed Edwards’s Department of Corrections ankle monitor was at St.
    Paul Street at 10:00 on the night in question, and that the entries before and after that showed that
    the GPS was “unable to locate” the ankle monitor. The State argues this “show[ed] that Edwards
    was at a completely different location” than defendant and complainant. But neither piece of
    impeachment evidence is necessarily inconsistent with Edwards’s proffered testimony—it was
    reasonably possible that the witness misunderstood defendant or misreported what he said, or that
    35
    defendant lied about being alone in the car; and it was entirely possible that Edwards had removed
    his ankle monitor. Absent any clear indication of perjury, the question of whether, and how much,
    to believe Edwards’s exculpatory testimony should have gone to the jury.
    ¶ 85.   Edwards’s testimony was also essential.        Apart from defendant’s testimony,
    Edwards’s testimony was the only evidence defendant had to contradict complainant’s account of
    what happened in the car.11 Moreover, there was a strong chance it might have been, as defendant
    puts it, “game changing.” Out of the four counts—domestic assault by burning with a cigarette,
    unlawful restraint, kidnapping, and interference with access to emergency services—the jury
    acquitted on three, suggesting that it did not find complainant completely credible. Moreover, as
    reflected in the majority’s opinion above, the jury deadlocked for some time on Count 1, the
    domestic-assault charge. The jury’s struggle to reach a verdict on Count 1 suggests that if
    defendant had been able to introduce testimony corroborating his version of events and
    undercutting complainant’s, there is a reasonable probability that the jury might have acquitted
    him on Count 1 along with the other charges.
    ¶ 86.   Finally, the State did not present any strong countervailing interest against granting
    immunity. On appeal, the State argued “it had a strong interest in prosecuting Edwards for perjury
    if he lied at trial about being physically present during the charged offenses.” This asserted reason
    does not actually countervail against allowing Edwards to testify, as the State is free to prosecute
    a witness for perjury committed in the course of giving immunized testimony. See 12 V.S.A.
    § 1664(a) (providing that immunity does not bar prosecution for perjury in immunized testimony).
    Moreover, as discussed more fully above, the proffered testimony is not so “overwhelmingly
    11
    The record contains references to Edwards’s uncounseled deposition testimony.
    However, the testimony is not itself in the record, and nobody made any proffers as to its content,
    so there is no basis to conclude that the deposition testimony would have served as an adequate
    alternative.

    undercut or undermined by substantial prosecution evidence” that it is “so lacking in credibility
    that it cannot be clearly exculpatory.”

    -63 (emphasis omitted).
    ¶ 87.   We can imagine a wide range of scenarios that would countervail against a grant of
    immunity, such as where the State wishes to protect an ongoing investigation into or prosecution
    against the witness, or where the State has reason to believe co-conspirators are planning to falsely
    exonerate each other. The State has not, however, articulated one here.
    ¶ 88.   The remedy for this due process violation “is a retrial where the Government can
    cure the distortion caused by its wrongdoing or face dismissal of the relevant charges.” 
    Quinn, 728 F.3d at 248
    . For that reason, I would reverse and remand for a new trial.
