Jury Instructions in Criminal Trials
Canadian Criminal Case Law Summary
As Driving while disqualified lawyers, we rely on R. v. Lewis when defending cases where the Crown alleges someone knowingly drove while under a court-ordered prohibition. This Supreme Court of Canada decision highlights how carefully a jury must be instructed when determining whether an accused person intentionally committed the offence.
In R. v. Lewis, the Court emphasized that juries must clearly understand the legal test before they convict. The distinction between simply being connected to an event and intentionally committing a criminal act is crucial. In driving while disqualified cases, that often means proving the accused knew about the prohibition and still chose to drive.
This case matters in real life because many people are charged not as the main actor, but as someone who allegedly helped. The way the jury is guided can determine the outcome of the entire trial.

The Legal Issue Before the Court
The central issue was whether the jury had been properly instructed on how to assess the accused’s role in the alleged offence. The accused was not necessarily the principal offender. The question was whether the judge clearly explained what it means to aid or abet under the Criminal Code.
If a jury misunderstands the legal test, it may convict someone without properly applying the law. That is why jury instructions are so important.
What the Court Confirmed
The Supreme Court confirmed that trial judges must carefully and clearly explain party liability. The jury must understand:
• The difference between committing the offence and helping commit it
• That mere presence at the scene is not enough
• That there must be intentional assistance or encouragement
If those elements are not clearly explained, the verdict may be unsafe.
Why This Case Matters in Real Cases
Many people charged with serious offences are not accused of physically committing the act. Instead, the Crown argues they assisted or encouraged someone else. That can include driving someone to a location, being present during an incident, or allegedly supporting the act in some way.
R. v. Lewis reminds courts that helping is not assumed. The Crown must prove intentional participation. A person cannot be convicted simply because they were nearby or associated with someone else involved.
How This Case Shapes Defence Strategy
This case shapes defence strategy in several important ways.
First, it allows defence counsel to carefully examine the judge’s instructions to the jury. If the explanation of aiding or abetting is unclear, that can become a strong appeal issue.
Second, it reinforces that presence alone is not guilt. Defence strategy often focuses on separating association from participation.
Third, it ensures that juries must focus on intent. Without proof that the accused meant to assist, there should be no conviction as a party.
What This Case Means for You
If you are charged because police believe you helped someone commit a crime, the legal test is very specific. Being present is not enough. Association is not enough. The Crown must prove intentional assistance or encouragement.

Frequently Asked Questions
Q. What does it mean to aid or abet a crime?
A. Aiding or abetting means intentionally helping or encouraging someone else commit an offence. It is not enough to simply be present. The Crown must prove that you meant to assist in the crime. If there is no clear proof of intent, a conviction should not follow.
Q. Can I be convicted just for being at the scene?
A. No. Mere presence at the scene of a crime is not automatically guilt. The law requires proof that you actively participated or encouraged the offence. Courts are clear that being nearby, without more, is not enough for conviction.
Q. Why are jury instructions so important?
A. Jury instructions guide how jurors apply the law to the facts. If the legal test is explained incorrectly, the jury may misunderstand what must be proven. That can result in an unfair verdict. R. v. Lewis reinforces that clarity is essential.
Q. Can improper jury instructions lead to an appeal?
A. Yes. If a judge fails to properly explain the law on aiding or abetting, it can form the basis of an appeal. Appellate courts closely review jury instructions in serious criminal cases. Errors in explaining the law can result in a new trial.
Q. What should I do if I am charged as a party to an offence?
A. You should speak with a criminal defence lawyer immediately. Party liability cases often turn on small factual details and the issue of intent. Early legal advice can help protect your rights and shape your defence strategy from the start.
