Pappajohn v The Queen
[1980] 2 SCR 120
Pappajohn v. The Queen
[1980] 2 S.C.R. 120
Supreme Court of Canada — Martland, Pigeon, Dickson, Beetz, Estey, McIntyre and Chouinard JJ. | October 22, 1979; May 20, 1980
Background
George Pappajohn, a Vancouver businessman, met with a real estate saleswoman to discuss selling his house. After a lengthy lunch with considerable alcohol consumption, they went to his home to continue discussions. What happened next became the subject of fierce dispute. The complainant testified that Pappajohn forcibly raped her — pushing her down a hallway, removing her clothes against her will, tying her up with neckties and bathrobe cords, and sexually assaulting her multiple times while she screamed and resisted. She eventually escaped naked from the house and sought help from neighbors.
Pappajohn told a completely different story. He claimed the encounter was entirely consensual — that she willingly participated in sexual activity including bondage, that there was no force or resistance, and that she only became hysterical after he went to get cigarettes. The trial judge refused to instruct the jury on the defence of "mistake of fact" regarding consent, ruling there was insufficient evidence to support such a defence. Pappajohn was convicted of rape.
Issues
- When must a trial judge put the defence of mistake of fact to a jury in sexual assault cases?
- What standard applies — must the mistaken belief be both honest and reasonable, or just honest?
The Mistake of Fact Defence
The Supreme Court established crucial principles about when this defence becomes available. The majority ruled that for any defence to go to a jury, there must be sufficient evidence in the record to give it "an air of reality." You can't just assert a mistaken belief — there must be some evidence, beyond the accused's own testimony, that could reasonably support the defence.
In this case, the Court found the complainant's evidence completely excluded any possibility of consent or mistaken belief about consent. Her testimony described a terrified, hysterical woman who actively resisted throughout. The accused's version spoke of actual consent, not mistaken belief about consent. As the Court noted: "The two stories are diametrically opposed on this vital issue." There was no middle ground evidence that could support a genuine but mistaken belief.
The Court also clarified that in Canada, following Beaver v. The Queen, a mistaken belief about consent must be both honest and reasonable. The English approach allowing purely subjective (honest but unreasonable) beliefs was rejected as inconsistent with Canadian criminal law principles.
Key Takeaway
A defence of mistake of fact requires actual evidence beyond self-serving testimony — you can't manufacture a defence through creative storytelling.
While this is a criminal case, the evidentiary principles apply broadly: courts require objective evidence to support any defence, not just the accused's version of events. The "air of reality" test ensures that defences have some foundation in the evidence before being considered.
