Facts
- The accused participated in a maritime scheme to transport a large quantity of marijuana from Colombia toward Alaska, intending to remain outside Canadian territorial waters.
- While off the coast of British Columbia, the vessel developed serious mechanical problems in worsening weather conditions.
- For safety, the captain altered course into Canadian waters to seek shelter and make repairs.
- The vessel grounded in a sheltered cove; to prevent capsizing, the crew offloaded much of the marijuana onto shore.
- Police arrived after most of the cargo had been moved ashore.
- The accused were charged with importing cannabis into Canada and possessing cannabis for the purpose of trafficking under federal narcotics legislation.
- At trial, the accused relied primarily on the common-law defence of necessity, asserting that the peril at sea compelled entry into Canada and offloading.
- The jury acquitted; the provincial appellate court set aside the acquittals and ordered a new trial based on errors in the trial proceedings and instructions.
Issues
- Whether the common-law defence of necessity operates as a justification or as an excuse.
- What elements and thresholds govern necessity, including imminence of peril, the absence of reasonable legal alternatives, and proportionality.
- Whether the jury instructions on necessity accurately conveyed the required legal test.
Decision
- The Supreme Court dismissed the accused’s appeal and affirmed the order for a new trial.
- Necessity was recognized as an excuse, not a justification.
- The Court held that necessity is available only in narrow circumstances: clear and imminent peril, demonstrable impossibility of lawful compliance (no reasonable legal alternative), and proportionality between the harm inflicted and the harm avoided.
- The trial judge’s charge, taken as a whole, was too broad and could have led the jury to acquit based on a general reasonableness standard rather than the strict necessity requirements.
Legal Principles
- Necessity is an excusing doctrine: it does not render the prohibited act socially right; it excuses conduct that was realistically unavoidable in an emergency.
- The defence is confined to urgent situations of clear and imminent peril.
- The accused must show that compliance with the law was demonstrably impossible, meaning there was no reasonable legal alternative to avoid the peril.
- Proportionality is required: the harm caused by the illegal act must not outweigh the harm avoided.
- The doctrine rests on a practical concept of involuntariness assessed against societal expectations of normal resistance to pressure; it must be strictly limited to prevent it from becoming a general permission to break the law.
Conclusion
The Court confirmed necessity as a tightly confined common-law excuse and ordered a new trial because the jury instructions did not adequately require findings of imminent peril, no reasonable legal alternative, and proportionality before the defence could succeed.
