Beyond a Reasonable Doubt (Standard)

R. v. Bisson, 1998 CanLII 810 (SCC), [1998] 1 SCR 306

3 At the outset it is important to remember that the directions in this case and the consideration of them by the Court of Appeal took place before the release of the decision of this Court in R. v. Lifchus, 1997 CanLII 319 (SCC), [1997] 3 S.C.R. 320. The trial judge instructed the jury that although the phrase “beyond a reasonable doubt” can cause considerable debate and confusion, it was really a very simple concept. He stated that, while total, absolute, perfect certainty does not exist, certainty beyond a reasonable doubt is that which is closest to this ideal. He described it as a real doubt, an honest doubt held by a reasonable person. He then explained, however, that a reasonable doubt is a or that degree of certainty which one uses every day in important activities. He put it in this way:

[TRANSLATION] What is reasonable doubt? I will not hide from you the fact that it is a legal concept which has provoked much debate, which has engendered much discussion, both on the part of counsel and on the part of judges, and which is the source of confusion that is sometimes quite unnecessary. You will see that it is something very simple.

The expression reasonable doubt is in a sense a way of describing a degree of certainty. First, you should note, and obviously accept, the fact that total, absolute, perfect certainty that someone is guilty of something, does not exist. Just as in most situations in our everyday life, total, perfect, complete certainty does not exist, the closest that one can get to this ideal state of certainty is precisely certainty beyond a reasonable doubt.

What then is a reasonable doubt? A reasonable doubt is first and foremost a real doubt, that is not imagined, not capricious, not frivolous. It is a real doubt, an honest doubt entertained in the mind of a reasonable person. A reasonable doubt is therefore a doubt that is reasonable. It is nothing other than that. And it is a degree of certainty which you use every day, in your important activities, whether at work, at home or in your leisure activities. It is a degree of certainty which you employ, which you have used since you reached the age of reason, without perhaps having dissected it as we are doing at present.

Therefore, this concept of reasonable doubt is in fact an expression, or a manner, perhaps not always a good one, of expressing a degree of certainty, certainty beyond a reasonable doubt. I want to give you an example to show you that it is a degree of certainty which you use, which you employ, which you know, and which you are asked to use in determining the guilt of the accused. I am saying to you because others may read what I’m telling you, I’m giving you the example I have used for years. I will not change my example because I like it, it does the job, I will not change it.

You know that in North America, the automobile is something as essential as a refrigerator, as a telephone, because we live in a country which is very large. [Emphasis added.]
