In R v Bouvette [“Bouvette”], the Supreme Court of Canada (“SCC”) confronted a remedial question at the intersection of prosecutorial discretion and appellate authority. When a conviction is quashed for miscarriage of justice, in what circumstances should a court of appeal enter an acquittal rather than order a new trial or impose a judicial stay, particularly where the Crown supports an acquittal and undertakes to call no evidence on retrial?
Facts
In 2011, Tammy Bouvette was charged with second degree murder following the death of her 19-month-old child. The charge was largely predicated on the expert opinion of Dr. Evan Matshes, who concluded that the child’s injuries were consistent with homicide (paras 16–18). At a preliminary inquiry, Dr. Matshes testified that internal reviews revealed no concerns (para 263). On that basis, Ms. Bouvette was committed to stand trial for murder (paras 212, 216).
In 2014, facing the prospect of a lengthy custodial sentence, Ms. Bouvette pled guilty to the lesser offence of criminal negligence causing death and received a penitentiary sentence (paras 218, 271). Years later, it emerged that the Crown had failed to disclose material information directly affecting Dr. Matshes’ credibility and reliability (paras 210–213). An external peer review found his conclusions to be unreasonable in 13 of the 14 cases examined, including Ms. Bouvette’s (paras 216, 263). The undisclosed material also undermined preliminary inquiry testimony (para 263).
Following an independent review by a specially appointed prosecutor, Ms. Bouvette obtained an extension of time to appeal and applied to adduce fresh evidence (paras 204, 226–227). The Crown ultimately conceded that the non-disclosure constituted a miscarriage of justice and that her guilty plea was uninformed (paras 212, 261).
Judicial History
The British Columbia Court of Appeal allowed the appeal and quashed the conviction pursuant to s. 686(1)(a)(iii) of the Criminal Code[Code] on the basis of a miscarriage of justice arising from the Crown’s material non-disclosure (paras 209–213, 295). The Court accepted that the undisclosed peer review evidence directly undermined the reliability and credibility of Dr. Matshes’ opinion and bore on Ms. Bouvette’s decision to plead guilty (paras 212–213). It concluded that, had disclosure been made, the plea would not have been entered.
Having set aside the conviction, the Court of Appeal turned to the appropriate remedy under s. 686(2). It first considered whether an acquittal was warranted. Applying the unreasonable verdict framework and drawing on R v Truscott, the Court held that it could not conclude that no reasonable jury, properly instructed, could convict on the available record (paras 231–232, 288). It emphasized that a new trial was not legally impossible and that the appellate record was insufficiently complete to permit a full merits-based determination of guilt or innocence (paras 237–240). In its view, the absence of a trial record and the theoretical possibility that the Crown could seek to proceed again weighed against entering an acquittal.
The Court of Appeal therefore declined to substitute an acquittal and instead entered a judicial stay of proceedings pursuant to s. 686(8) (paras 288–289). It reasoned that a stay was appropriate to prevent further unfairness while acknowledging that the threshold for an acquittal had not been met on the record before it.
Ms. Bouvette appealed to SCC, arguing that the Court of Appeal erred in foreclosing a broader inquiry into whether an acquittal was warranted in the interests of justice (para 299). Before the SCC, the Crown supported the entry of an acquittal and undertook that it would call no evidence at any retrial (paras 252, 261–262).
Issue
Once a conviction has been quashed for miscarriage of justice under s. 686(1)(a)(iii) of the Code, in what circumstances may an appellate court enter an acquittal under s. 686(2) rather than order a new trial or impose a judicial stay of proceedings?
Background
Section 686 of the Code governs appellate remedies in criminal cases. Where an appeal court concludes that a conviction constitutes a miscarriage of justice, it must quash the conviction and then determine the appropriate remedy (para 295). Section 686(2) sets out two primary options: an acquittal or order for a new trial (paras 229, 283). Separately, s. 686(8) authorizes ancillary orders, including a judicial stay of proceedings, which has been characterized as a remedy of last resort (paras 284–286).
Historically, appellate courts have entered acquittals where no reasonable jury could convict (paras 231, 242). However, in cases outside the norm, most notably R v Truscott, courts have exercised broader remedial discretion, considering the strength of the remaining case, the likelihood of a retrial, and the overall equities facing a wrongfully convicted appellant (paras 233–236, 296–298). R v Bouvette required the Court to clarify the scope of that discretion and to delineate the relationship between acquittals, new trials, and judicial stays in cases bearing the procedural and substantive hallmarks of wrongful conviction (paras 296–299).
Decision
Majority Reasons
Writing for the majority, Kasirer J. allowed the appeal and entered an acquittal under s. 686(2) of the Code (paras 299–300). He held that, once a conviction is quashed for miscarriage of justice under s. 686(1)(a)(iii), appellate courts must decide between an acquittal and a new trial. While an acquittal is mandatory where no reasonable jury could convict, that strict unreasonable verdict standard is not the exclusive pathway to acquittal (paras 242–244, 295–296).
Kasirer J. clarified and systematized the approach to discretionary acquittals in miscarriage of justice cases. In cases exhibiting the procedural and substantive hallmarks of wrongful convictions, courts must consider three interrelated factors: the nature and effects of the miscarriage of justice; the likelihood and viability of a retrial, including the strength of the Crown’s remaining case; and the overall equities of the case (paras 206, 296–298). The central merits-based inquiry is whether it is more probable than not that the accused would be acquitted at a hypothetical retrial applying the reasonable doubt standard (paras 246, 265, 297).
Applying that framework, Kasirer J. emphasized the seriousness of the Crown’s non-disclosure, the reliability concerns surrounding the expert evidence, and Ms. Bouvette’s vulnerability and uninformed guilty plea (paras 210–216, 221–222). The Crown conceded that its case on retrial would be weak and undertook to call no evidence if a new trial were ordered (paras 252, 261–263). On the augmented record, it was more likely than not that Ms. Bouvette would be acquitted (para 265).
Kasirer J. further held that a judicial stay under s. 686(8) is a last-resort remedy, and since an acquittal was justified, a stay was unnecessary (para 287).
Concurring Reasons
Martin J. agreed that the appeal should be allowed and that an acquittal was appropriate, but wrote separately to clarify the scope of appellate discretion under s. 686(2). In her view, the British Columbia Court of Appeal erred in treating the possibility of retrial as effectively foreclosing consideration of an acquittal (paras 237–240, 299).
Martin J. emphasized that Parliament conferred a broad remedial discretion under s. 686(2), which does not require courts to treat a new trial as presumptive whenever a reasonable possibility of conviction remains (paras 165–173, 175–177). She rejected the characterization that acquittals in miscarriage of justice cases as “exceptional” (para 198). Instead, the statutory text authorizes appellate courts to enter acquittals whenever doing so is justified in the interests of justice.
Her reasons stress that miscarriages of justice often arise in contexts marked by recognized hallmarks of wrongful convictions, including non-disclosure, unreliable expert evidence, false guilty pleas, and systemic disadvantage (paras 203–221). In such cases, courts must be attentive to the broader purpose of s. 686, namely preventing and remedying wrongful convictions (paras 207–208, 296).
For Martin J., the power to enter an acquittal is not extraordinary but an integral component of the appellate court’s remedial mandate. Where, as here, the miscarriage of justice undermined the safety of the conviction and a retrial would serve no meaningful public interest, the interests of justice require a final and complete remedy.
Analysis
One of the most consequential aspects of R v Bouvette lies not in the acquittal itself, but in the Court’s clarification of the constitutional relationship between prosecutorial discretion and judicial authority. The case squarely confronts a subtle but significant question: when the Crown concedes that an acquittal is appropriate and undertakes to call no evidence at a retrial, is the appellate court merely formalizing that decision, or must it independently justify the remedy under s. 686(2) of the Code?
Kasirer J. clarified that the power to enter an acquittal belongs to the court, not the Crown. While the Crown’s position is entitled to “significant weight” (para 253), the ultimate decision remains a judicial one (para 254). Parliament vested appellate courts, not prosecutors, with the authority to enter acquittals after quashing convictions. Even in the face of a concession, courts are not bound by positions advanced by either party (para 256). This insistence reflects a foundational principle: prosecutorial discretion governs charging and litigation strategy, but once a matter is before the court, remedial authority rests firmly with the judiciary.
At the same time, the Court makes clear that meaningful judicial supervision does not require reflexive distrust of prosecutorial concessions. Kasirer J. recognizes that when both the Crown and defence jointly submit that an acquittal is appropriate, such a position attracts the “respect and deference normally given to joint submissions” (para 258). The Crown, as a quasi-minister of justice, is presumed to act in good faith and in the public interest. A concession that an acquittal is warranted signals that the Crown has assessed the remaining case as weak and determined that further proceedings would not advance the public interest. In this way, the Court acknowledges the institutional competence of prosecutors to evaluate the viability of a retrial without collapsing the judicial role into mere rubber stamping.
Yet the deference is not abdication. Even where the Crown confirms it would call no evidence at a new trial (paras 252, 262), the court must still conduct an independent review of the record and be satisfied that an acquittal is appropriate (para 259). This dual posture preserves the separation of institutional roles. The prosecutor may decide whether to proceed, but only the court may formally declare legal innocence. As the Court reiterates, “no one in this country is entitled to their own law” (para 256). Judicial supervision ensures that acquittals are grounded in legal principle rather than prosecutorial grace.
This clarification is particularly significant in miscarriage of justice cases. As the Court notes, individuals who are wrongfully convicted may remain burdened by “significant stigma” and left “without the chance of a not guilty verdict” where proceedings are merely stayed (para 278). A prosecutorial stay lacks finality, and leaves open the theoretical possibility of re-prosecution, perpetuating uncertainty and reputational harm. For individuals who have already endured the trauma of wrongful conviction, incarceration, and public condemnation, the absence of a formal acquittal can prolong social, psychological, and economic consequences. These harms often fall disproportionately on those already facing systemic disadvantage, who are overrepresented among wrongful conviction cases. By insisting that appellate courts retain responsibility for the remedial decision, Bouvette strengthens access to justice by ensuring that those whose convictions are unsafe are not left in legal limbo. An acquittal provides both finality and a public declaration that the state has failed to prove guilt beyond a reasonable doubt.
In the end, Bouvette articulates a careful equilibrium. Crown concessions matter deeply; they inform the court’s assessment of the merits and the public interest. But they do not displace judicial authority. The acquittal power under s. 686(2) is neither an extension of prosecutorial discretion nor a mechanical response to it. It is an exercise of independent judicial judgment, one that must be reasoned, justified, and anchored in the interests of justice.
