A recent Ontario court decision has once again raised serious concerns about prosecutorial conduct in the province. A judge dismissed a criminal case after finding what was described as “unacceptable negligence” by Toronto Crown attorney Marnie Goldenberg, marking the latest in a series of controversies that have drawn scrutiny from defence lawyers, judges, and members of the public.
For advocates focused on wrongful convictions and systemic reform, the decision highlights a troubling reality: the integrity of the justice system depends not only on police investigations and judicial oversight, but also on the conduct of prosecutors entrusted with seeking justice rather than securing convictions.
A Growing Pattern of Concern
The case follows earlier allegations involving Goldenberg that received widespread media attention. In a separate matter, a Toronto police officer alleged that the Crown attorney reacted negatively after testimony that did not support the prosecution’s theory of the case. The officer later claimed Goldenberg suggested police should “protect our own,” an allegation she has strongly denied.
While the specific facts of each case differ, the recurring judicial criticism has amplified concerns about disclosure obligations, witness management, and prosecutorial accountability. The latest ruling suggests that the court found the conduct in question serious enough to undermine confidence in the fairness of the proceedings.
Why Prosecutorial Conduct Matters
In Canada, Crown attorneys have a unique role. Unlike defence lawyers, their primary duty is not to win cases but to ensure justice is done. This obligation includes:
- Disclosing relevant evidence to the defence.
- Presenting evidence fairly and objectively.
- Avoiding conduct that could prejudice the accused.
- Protecting the integrity of the judicial process.
When prosecutors fail to meet these obligations, the consequences can be severe. Cases may be delayed, convictions may be overturned, and in extreme circumstances, charges may be stayed or dismissed altogether.
More importantly, such failures can contribute to wrongful convictions—the very outcome the justice system is designed to prevent.
The Wrongful Conviction Connection
Many of Canada’s most notorious wrongful conviction cases have involved some combination of:
- Inadequate disclosure.
- Tunnel vision by investigators.
- Unreliable expert evidence.
- Prosecutorial errors or misconduct.
These factors often work together, creating a system where innocent people can be convicted while the actual truth remains hidden.
Organizations such as Miscarriage of Justice Canada have identified these systemic failures as a key area of concern. The organization was created to assist individuals who may have been wrongfully convicted, particularly in non-homicide cases that often fall outside the scope of existing innocence organizations. Its mission includes investigating claims of wrongful conviction and helping applicants seek review through Canada’s new Miscarriage of Justice Review Commission.
Accountability Must Extend Beyond Individual Cases
When judges repeatedly criticize the conduct of prosecutors, the issue extends beyond any single case. It raises broader questions:
- Are adequate safeguards in place to prevent prosecutorial errors?
- How are complaints against Crown attorneys investigated?
- What transparency exists when judges make findings of serious misconduct or negligence?
- How can public confidence be restored when cases collapse because of actions by those responsible for upholding justice?
These questions are particularly important as Canada enters a new era of wrongful conviction review with the establishment of the Miscarriage of Justice Review Commission, created under Bill C-40. The commission was designed to provide independent review of potential miscarriages of justice and increase public confidence in the system.
Looking Forward
The dismissal of another criminal case due to prosecutorial conduct should concern everyone—not because charges were stayed, but because justice depends on public confidence that legal proceedings are fair, transparent, and conducted according to the highest professional standards.
Every time a case is dismissed because of prosecutorial negligence, victims are denied resolution, accused persons face prolonged uncertainty, and public trust in the justice system is weakened.
The lesson from this latest ruling is clear: accountability is not optional. If Canada is serious about preventing wrongful convictions and strengthening confidence in its justice system, meaningful oversight of prosecutorial conduct must remain a priority.
For organizations working to uncover miscarriages of justice, these cases serve as a reminder that vigilance, transparency, and independent review remain essential safeguards against wrongful conviction.
