Presumption of Innocence, Burden of Proof and Reasonable Doubt
9.2 Presumption of Innocence, Burden of Proof and Reasonable Doubt
- (Last revised June 2012)
-  The first and most important principle of law applicable to every criminal case is the presumption of innocence. (NOA) enters the proceedings presumed to be innocent, and the presumption of innocence remains throughout the case unless the Crown, on the evidence put before you, satisfies you beyond a reasonable doubt that s/he is guilty.
-  Two rules flow from the presumption of innocence. One is that the Crown bears the burden of proving guilt. The other is that guilt must be proved beyond a reasonable doubt. These rules are linked with the presumption of innocence to ensure that no innocent person is convicted.
-  The burden of proof rests with the Crown and never shifts. There is no burden on (NOA) to prove that s/he is innocent. S/he does not have to prove anything.
-  Now what does the expression “beyond a reasonable doubt” mean? A reasonable doubt is not an imaginary or frivolous doubt. It is not based on sympathy for or prejudice against anyone involved in the proceedings. Rather, it is based on reason and common sense. It is a doubt that arises logically from the evidence or from an absence of evidence.
-  It is virtually impossible to prove anything to an absolute certainty, and the Crown is not required to do so. Such a standard would be impossibly high. However, the standard of proof beyond a reasonable doubt falls much closer to absolute certainty than to probable guilt. You must not find (NOA) guilty unless you are sure s/he is guilty. Even if you believe that (NOA) is probably guilty or likely guilty, that is not sufficient. In those circumstances, you must give the benefit of the doubt to (NOA) and find him/her not guilty because the Crown has failed to satisfy you of his/her guilt beyond a reasonable doubt.
-  In a few moments I will explain the essential elements that the Crown must prove beyond a reasonable doubt to establish (NOA)’s guilt. For the moment, the important point for you to understand is that the requirement of proof beyond a reasonable doubt applies to each of those essential elements. It does not apply to individual items of evidence. You must decide, looking at the evidence as a whole, whether the Crown has proved (NOA)’s guilt beyond a reasonable doubt.
-  If you have a reasonable doubt about (NOA)’s guilt arising from the evidence, the absence of evidence, or the credibility or the reliability of one or more of the witnesses, then you must find him/her not guilty.
-  In short:
- 1. The presumption of innocence applies at the beginning and continues throughout the trial, unless you are satisfied, after considering the whole of the evidence, that the Crown has displaced the presumption of innocence by proof of guilt beyond a reasonable doubt.
- 2. If, based upon the evidence, you are sure that (NOA) is guilty of the offence(s) with which s/he is charged, that demonstrates that you are satisfied of his/her guilt beyond reasonable doubt, and you must find him/her guilty of that offence.
- 3. If you have a reasonable doubt whether (NOA) is guilty of the offence(s) with which s/he is charged, you must give him/her the benefit of that doubt and find him/her not guilty.

Proof Beyond a Reasonable Doubt
It must be explained that:
- "the standard of proof beyond a reasonable doubt is inextricably intertwined with that principle fundamental to all criminal trials, the presumption of innocence;"
- "the burden of proof rests on the prosecution throughout the trial and never shifts to the accused;"
- "a reasonable doubt is not a doubt based upon sympathy or prejudice;"
- "rather, it is based upon reason and common sense;"
- "it is logically connected to the evidence or absence of evidence;"
- "it does not involve proof to an absolute certainty; it is not proof beyond any doubt nor is it an imaginary or frivolous doubt;" and
- "more is required than proof that the accused is probably guilty ‑‑ a jury which concludes only that the accused is probably guilty must acquit."
Assessment of Evidence
9.4 Assessment of Evidence
- (Last revised June 2018)
-  To make your decision, you should consider carefully, and with an open mind, all the evidence presented during the trial. It will be up to you to decide how much or little of the testimony of any witness you will believe or rely on. You may believe some, none or all of the evidence given by a witness.
-  When you go to the jury room to consider the case, use your collective common sense to decide whether the witnesses know what they are talking about and whether they are telling the truth. There is no magic formula for deciding how much or how little to believe of a witness’s testimony or how much to rely on it in deciding this case. But here are a few questions you might keep in mind during your discussions.
-  Did the witness seem honest? Is there any reason why the witness would not be telling the truth?
-  Does the witness have any reason to give evidence that is more favourable to one side than to the other?
-  Was the witness in a position to make accurate and complete observations about the event? Did s/he have a good opportunity to do so? What were the circumstances in which the observation was made? What was the condition of the witness? Was the event itself unusual or routine?
-  Did the witness seem to have a good memory? Does the witness have any reason to remember the things about which s/he testified? Did any inability or difficulty that the witness had in remembering events seem genuine, or did it seem made up as an excuse to avoid answering questions?
-  Did the witness seem to be reporting to you what he or she saw or heard, or simply putting together an account based on information obtained from other sources, rather than personal observation?
-  Did the witness’s testimony seem reasonable and consistent? Is it similar to or different from what other witnesses said about the same events? Did the witness say or do something different on an earlier occasion?
-  Do any inconsistencies in the witness’s evidence make the main points of the testimony more or less believable and reliable? Is the inconsistency about something important, or a minor detail? Does it seem like an honest mistake? Is it a deliberate lie? Is the inconsistency because the witness said something different, or because s/he failed to mention something? Is there any explanation for it? Does the explanation make sense?
-  What was the witness’s manner when he or she testified? Do not jump to conclusions, however, based entirely on how a witness has testified. Looks can be deceiving. Giving evidence in a trial is not a common experience for many witnesses. People react and appear differently. Witnesses come from different backgrounds. They have different abilities, values and life experiences. There are simply too many variables to make the manner in which a witness testifies the only or most important factor in your decision.
-  These are only some of the factors that you might keep in mind when you go to your jury room to make your decision. These factors might help you decide how much or little of a witness’s evidence you will believe or rely on. You may consider other factors as well.
-  In making your decision, do not consider only the testimony of the witnesses. Take into account, as well, any exhibits that have been filed and decide how much or little you will rely on them to help you decide this case. I will be telling (or, have already told) you about how you use admissions in making your decision.
-  It must not be suggested to the jury that they can assume that the accused, by virtue of his or her status as the accused, would lie to escape conviction, as this undermines the presumption of innocence: R v Laboucan,  1 SCR 397, at paras 14-18.
-  Paragraph  is directed at witnesses who may have put their testimony together, or embellished their account from outside sources, such as media accounts or other sources. It may require modification where the source is records whose accuracy, and the propriety of consulting them, is not in issue.
-  Where a witness is testifying through an interpreter, this instruction may be expanded to point out the particular difficulties in assessing such a witness’s testimony.

Reasonable Doubt and Credibility
9.5 Reasonable Doubt and Credibility
- (Last revised June 2012)
-  I am going to speak to you for just a moment about reasonable doubt and credibility. Reasonable doubt applies to the issue of credibility. On any given point, you may believe a witness, disbelieve a witness, or not be able to decide. You need not fully believe or disbelieve one witness or a group of witnesses. If you have a reasonable doubt about (NOA)’s guilt arising from the credibility of the witnesses, then you must find him/her not guilty.
Testimony of Accused
9.6 Testimony of Person Charged (The W. (D.) Instruction)
- (Last revised June 2012)
-  You have heard (NOA) testify. When a person charged with an offence testifies, you must assess that evidence as you would assess the testimony of any other witness, keeping in mind my instructions to you earlier about the credibility of witnesses. You may accept all, part, or none of (NOA)’s evidence.
-  Of course, if you believe the testimony of (NOA) that s/he did not commit the offence charged, you must find him/her not guilty.
-  However, even if you do not believe the testimony of (NOA), if it leaves you with a reasonable doubt about his/her guilt (or, about an essential element of the offence charged (or, an offence)), you must find him/her not guilty (of that offence).
In “he said/she said” cases it has been suggested in R v C.W.H. (1991), 68 CCC (3d) 146 (BCCA) that the following instruction be added:
If you don't know whom to believe, it means you have a reasonable doubt and you must find (NOA) not guilty.
 Even if the testimony of (NOA) does not raise a reasonable doubt about his/her guilt, (or, about an essential element of the offence charged (or, an offence)), if after considering all the evidence you are not satisfied beyond a reasonable doubt of his /her guilt, you must acquit.
 R v W. (D.),  1 SCR 742. This instruction is appropriate where the evidence of the accused constitutes a complete defence to the offence charged. Where the testimony of the accused would only lead to a guilty verdict on an included offence based on, for example, intoxication or provocation, this instruction will need to be modified.
 It must not be suggested to the jury that they can assume that the accused, by virtue of his/her sta

9.7 Co-Accused's Comment on the Failure of Person Charged to Testify (The R v Prokofiew Instruction)
- (November 2012)
-  In his closing address (NOA2)’s counsel invited you to infer (NOA1)’s guilt from his/her failure to testify. This submission is wrong in law and you must ignore it. You cannot use (NOA1)’s silence at trial as evidence of his/her guilt.
-  Every accused person has the right to remain silent at trial. A person charged with an offence does not have to testify and has no obligation to prove anything. The burden of proof rests on the Crown from beginning to end.
-  You cannot find (NOA1) guilty of an offence unless you are satisfied on the basis of all the evidence that his/her guilt has been proven beyond a reasonable doubt. In reaching your verdict, you must not use (NOA1)’s silent at trial as evidence of his/her guilt.
-  This is a remedial instruction, based on R v Prokofiew, 2012 SCC 49, that should be used only where there are multiple accused and counsel for one of the accused has improperly invited the jury to infer the guilt of another accused from his or her failure to testify.
-  The instruction above corrects an improper comment that has been made before the jury. Even if there has been no improper comment on a co-accused's failure to testify, the judge has a discretion to give a limiting instruction where there is a realistic concern that the jury may place evidential value on an accused's decision not to testify (see: Prokofiew, at paras. 3-11). In crafting the instruction, care must be taken not to undermine the defence of the testifying accused. A possible instruction would use paragraphs - above, but substitute the following for paragraph , although this may need to be modified in light of the particular circumstances of the case:
In closing submissions you have heard mention of the fact that one of the accused did not testify. Bear in mind, however, that (NOA1)'s silence at trial is not evidence of his/her guilt.
