General Principles

There is no fixed formula for dealing with child witnesses.[1]

"Reasonable child" standard

The credibility of children is approached generally in the same way as adults. However, the standard of a "reasonable adult" may not be appropriate as a “reasonable child” may differ from that of an adult.[2] "Flaws, such as contradictions, in the testimony of a child may not toll so heavily against credibility and reliability as equivalent flaws in the testimony of an adult."[3] A child should not be held to the same "exacting standards" as an adult.[4] The evidence of a child must be approached on a "common sense" basis, "taking into account the strengths and weaknesses which characterize the evidence."[5]

Difference of Perception

Children "experience the world differently from adults", as such absence of details such as time and place are understandable and not necessarily fatal.[6] Stereotypes of children should be avoided.[7]

Same Standard of Scrutiny

Regardless, the standard of proof for the Crown is always the same and should be examined with the same level of scrutiny.[8]

Applying a higher degree of scrutiny on defence witnesses than Crown witnesses is an error of law.[9]

No Corroboration Needed

In certain cases, guilt can be found upon the testimony of a single child witness without corroboration.[10]

Inconsistencies

Guilt may also be found despite the presence of inconsistencies on material issues, lack of recent complaint, motive to lie and concoct, passage of time, and recovered memory.[11]

Passage of Time

The passage of a significant amount of time between the events and the laying of charges does not by itself warrant any caution.[12]

Recollection by Child

It is recognized that a child "will have a better recollection of events shortly after they occurred" than weeks or months after.[13]

Guidelines

Suggested guidelines include:[14]

  1. the credibility of child witnesses must be assessed carefully (in this context, “carefully” implies no bias either towards accepting or rejecting that evidence);
  2. the standard to be applied in assessing the credibility of a child witness is not necessarily the same as that applied to a reasonable adult;
  3. allowance must be made for the fact that young children may not be able to recount precise details and may not be able to communicate precisely the “when” and the “where” of an event, but their inability to do so should not lead to the conclusion that they have misperceived what has happened to them or who has done something to them;
  4. there is no assumption or presumption at law that a child’s evidence is less reliable than an adult’s;
  5. a common sense approach must be used in assessing the credibility of a child’s evidence, having regard to the age of the child, the child’s mental development and the child’s ability to communicate;
  6. inconsistencies, particularly concerning peripheral matters such as time or place, should not have the same adverse effect on the credibility of a child as it might in the case of an adult, having regard to the age and mental development of the child and other relevant factors;
  7. the burden of proof (guilt beyond a reasonable doubt) remains unchanged when the Crown case is founded upon the evidence of a child or children. Specifically, the rules pertaining to credibility as set out by the Supreme Court of Canada in R v D.W. do not change just because the Crown’s case is founded upon such evidence.
No Assumption of Unreliability

There can be no assumption that a witness is unreliable simply because of their age.[15] However, where the age is particularly young, such as where a 6 year old is testifying to a time when he was under 2 years old, then special considerations should be made.[16]

Child evidence that is graphic, clear, and unambiguous and is consistent with other witnesses are particularly compelling.[17]

Stereotypes of Children

It is an error of law for judges to rely on stereotypes on how children are expected to react in the circumstances of sexual offences.[18]

Methods Used When Interviewing Children

The conduct of a child interview may assist or detract from the reliability of the statement. Features assisting in reliability include:[19]

  • use of a small private room with comfortable seating;
  • limited number of people in the room;
  • questioning that is polite, simple, friendly, and non-leading;
  • absence of any intimidating demeanour, voice or language.

Recovered Memories

The accuracy of memories of children may be affected adversely by the use of therapy. Prudence must be taken in accepting recovered memories.[1]
