The Supreme Court of Canada has released what may become one of the most important criminal disclosure decisions in recent years. In Edmonton (Police Service) v. McKee, the Court unanimously reaffirmed a fundamental principle of Canadian justice: an accused person’s right to full answer and defence cannot be defeated by administrative record-keeping policies.
For those concerned with wrongful convictions, the implications of this decision are profound.
The Background
John McKee was facing drug and firearms charges arising from an investigation conducted by the Edmonton Police Service. During the proceedings, the defence learned that the lead detective had previously been found guilty of police misconduct. However, under Alberta’s police regulations, the disciplinary finding had been removed from the officer’s personnel record and was considered administratively “destroyed.”
The police service argued that because the record had been expunged, it no longer had to be disclosed to the Crown or to the defence.
The Supreme Court rejected that argument.
The Court’s Decision
Writing for a unanimous Court, Justice Martin held that relevant police misconduct information remains subject to disclosure obligations even if it has been removed from an officer’s disciplinary file pursuant to administrative policies or regulations. The Court made it clear that police services cannot avoid disclosure obligations simply by destroying or expunging records.
The Court emphasized several important principles:
- The constitutional right to make full answer and defence requires access to relevant police misconduct information.
- Administrative record-destruction policies cannot override constitutional disclosure obligations.
- Police agencies must provide potentially relevant misconduct information to the Crown.
- The Crown remains the gatekeeper responsible for determining whether the information must be disclosed to the accused.
The Court also clarified that disclosure obligations extend beyond misconduct that directly relates to honesty or credibility. Information may be relevant if it bears upon an officer’s reliability, professionalism, or conduct in the investigation.
Why This Decision Matters
Wrongful convictions often arise not from a single catastrophic error but from the cumulative effect of undisclosed information, tunnel vision, and the inability of the defence to effectively challenge the state’s case.
Police misconduct information can be critically important. It may reveal:
- prior dishonesty;
- improper investigative practices;
- failures to follow procedures;
- misconduct affecting credibility; or
- information supporting broader allegations of systemic problems within an investigation.
Without disclosure, an accused person may never know that important information existed, let alone be able to use it in their defence.
The history of wrongful convictions in Canada demonstrates the devastating consequences that can flow from disclosure failures. Cases such as those involving David Milgaard, Guy Paul Morin, and William Mullins-Johnson all illustrate the critical importance of ensuring that the defence receives all relevant information. Disclosure is not a technicality—it is one of the fundamental safeguards against convicting the innocent.
A Strong Message from the Supreme Court
Perhaps the most significant aspect of the decision is the message it sends to police services across Canada.
Constitutional rights cannot be circumvented through administrative processes. If relevant information once existed, the state cannot simply erase its disclosure obligations by deleting, destroying, or expunging records.
Transparency and accountability remain essential components of a fair criminal justice system.
The Broader Implications
The decision in McKee will likely require police services across Canada to re-examine their policies concerning disciplinary records and the preservation of information that may become relevant in future criminal proceedings.
For defence counsel, the case strengthens the ability to seek disclosure of police misconduct information.
For prosecutors, it reinforces their obligation to make meaningful inquiries of police agencies regarding potentially relevant records.
And for those concerned with miscarriages of justice, the decision represents an important reaffirmation that fairness and transparency must prevail over administrative convenience.
Conclusion
The Supreme Court’s decision in Edmonton (Police Service) v. McKee is more than a ruling about police disciplinary records. It is a reaffirmation of a core constitutional principle: an accused person is entitled to all relevant information necessary to make full answer and defence.
When disclosure fails, justice itself is put at risk.
By ensuring that potentially relevant police misconduct information cannot simply disappear through administrative processes, the Supreme Court has strengthened one of the most important safeguards against wrongful conviction in Canada.
