Crown Applications to Re-Open a Criminal Case: What Defence Lawyers Should Know

Introduction

In criminal trials, the Crown’s ability to re-open its case is strictly limited. While courts may take a more flexible approach when the defence seeks to re-open proceedings, Crown applications are treated with caution and skepticism. The law prioritizes fairness to the accused and guards against prejudice, case-splitting, and erosion of the right to a fair trial.

When Can the Crown Seek to Re-Open a Case?

The Crown may only seek to re-open its case after it has closed its evidence and before a verdict is rendered. Once an accused is acquitted, the trial judge is functus officio and has no jurisdiction to revisit the decision. With one narrow technical exception, the Crown cannot re-open a case following an acquittal.

A Highly Restrictive Legal Framework

Courts apply a far more restrictive approach to Crown applications to re-open than to defence applications. The central question is whether allowing the Crown to re-open 

would cause legal prejudice to the accused. As a trial progresses, the risk of prejudice increases and the judge’s discretion correspondingly narrows.

Three Stages of Crown Applications

Before the Crown closes its case, judges have broad discretion to permit re-opening, such as recalling a witness to correct testimony. Any potential prejudice can usually be addressed through adjournments or further cross-examination.

After the Crown has closed its case but before the defence has elected how to respond, discretion is narrower. The Crown must demonstrate that the omission was inadvertent and that re-opening will not prejudice the defence.

Once the defence has elected to call evidence or testify, re-opening becomes exceptionally rare. At this stage, fairness to the accused dominates the analysis. Courts presume prejudice, and re-opening risks violating the accused’s right against self-incrimination and the rule against splitting the Crown’s case.

What the Crown Cannot Do

The Crown cannot re-open its case to fill gaps in its evidence or to respond tactically to the defence case. Courts will not consider whether the defence would have proceeded differently if the evidence had been called earlier, nor can prejudice be cured by allowing the defence to re-open its own case.

If the Crown’s Application Is Denied

If re-opening is refused, the Crown must either proceed without the evidence or enter a stay and recommence the prosecution. Restarting the case may trigger abuse of process or Charter arguments and will be scrutinized by the new trial judge.

Reply Evidence vs. Re-Opening

Reply evidence and re-opening are related but distinct concepts. Reply evidence is permitted only where an issue arises unexpectedly from the defence case and could not reasonably have been anticipated. Re-opening, by contrast, requires the Crown to justify a departure from ordinary trial fairness principles and faces a much higher threshold.

Conclusion

Crown applications to re-open a criminal case are the exception, not the rule. Defence counsel should be alert to issues of prejudice, timing, and fairness, and be prepared to oppose late-stage applications vigorously. The law is clear: once the defence has begun to answer the case, due process will almost always outweigh the Crown’s interest in adding evidence.
