R v Erven

R. v. Erven

[1979] 1 S.C.R. 926
Supreme Court of Canada — Dickson J. (majority), Ritchie J. (dissenting) | December 21, 1978

Background

Keith Bruce Erven was caught up in a sophisticated hashish trafficking operation on the Nova Scotia coast. The plan involved caching 1,765 pounds of cannabis resin on Cape LaHave Islands and ferrying it by helicopter to a mainland cottage for packaging. Erven was a passenger on one of these helicopter flights, but there was no direct evidence he knew what cargo they were carrying.

When the helicopter dropped Erven and his companion Mayer back at Crescent Beach, two uniformed RCMP officers immediately confronted them. The officers were investigating suspicious activity but didn't yet know about the drug operation. When Mayer spun a story about collecting soil samples for "search and rescue," Constable Botham asked Erven if he was doing the same thing. Erven simply answered "Yes." Later, while in custody, Erven accepted clothing that officers had retrieved from the cottage where the hashish was found. The trial judge admitted both statements without holding a voir dire, despite defence counsel's objections, and convicted Erven of possession for trafficking.

Issues

1. Must a voir dire always be held to determine the admissibility of statements made by an accused to persons in authority?
2. Can statements be admitted without a voir dire if they appear "obviously voluntary" or "volunteered"?

The Voir Dire Requirement

The Supreme Court majority ruled that a voir dire must always be held when the Crown seeks to introduce statements made by an accused to persons in authority — no exceptions. The court rejected the "obviously voluntary" exception that some appeal courts had been applying, calling it "unsound." Justice Dickson emphasized that allowing statements in without a voir dire violates fundamental procedural safeguards: it denies the accused the right to call witnesses and testify on admissibility issues without prejudicing their right to remain silent at trial, and it blurs the crucial distinction between determining admissibility (the voir dire's job) and determining guilt (the trial's job).

The court was particularly concerned about protecting an accused person's right to challenge voluntariness. Even if Crown evidence makes a statement look voluntary, defence witnesses might tell a different story — but they can only be called after the Crown's case, by which time the statement has already poisoned the jury. As one judge noted: "Once the confession was read to the jury it was hopeless for the accused to call witnesses to show it was not a voluntary statement. The damage was done and could not be undone."

Key Takeaway

If police want to use your words against you, they must prove on a voir dire that you said them voluntarily — even if your statement seems obviously harmless or spontaneous.

This case established an ironclad rule protecting accused persons' rights. Any time you make a statement to police or other authorities, and the Crown wants to use it as evidence, your lawyer can demand a voir dire to challenge whether that statement was truly voluntary, regardless of the circumstances.
