Supreme Court of Canada Cases

R. v. Barton, 2019 SCC The defence of honest but mistaken belief in communicated consent requires that the accused honestly believed that the complainant had affirmatively communicated agreement to engage in the activity in question, effectively saying yes through words or actions.

R. v. Calnen, 2019 SCC As a general rule, the absence of supporting physical evidence does not make an inference from evidence of after-the-fact conduct speculative.

R. v. J.M., 2019 SCC Failure to attend a trial is not presumptively after-the-fact conduct rather, its admissibility must be determined on a case-by-case basis.

R. v. Le, 2019 SCC Although the implied licence doctrine allows the police to proceed from the street to the door of a house to facilitate convenient communication with an occupant, it does not permit entry into the backyard of the occupants home.

R. v. R.V., 2019 SCC Section 669.2 of the Criminal Code does not displace the general rule that a trial judge has the discretion to reconsider rulings made earlier in the proceedings if there were a material change in circumstances this discretion to reconsider applies to rulings made under s. 276.

R. v. Goldfinch 2019 SCC 38, 2019 CSC 38

This case provides guidance on the admissibility of evidence under section 276 of Code. In this case the evidence that the accused sough to admit under 276(1) was barred because it served no purpose other than to support inference that because complainant had consented in past, she was more likely to have consented on night in question. Although accused successfully demonstrated that evidence was of specific instances of sexual activity, he failed to establish that evidence was relevant to issue at trial.

R. v. Ball, 2019 BCCA The trial judge must instruct the jury not to use evidence adduced of the accuseds bad character to find the accused to be the type of person having the propensity to commit the offence, unless such evidence were central and inextricably linked to the motive or mechanism of the offence.

R v. Chafe, 019 ONCA Recognition evidence, which is subject to the same frailties and risks as other forms of identification evidence, requires the same level of assessment from the trier of fact.

R. v. Nurse, 2019 ONCA Evidence of non-verbal conduct intended or inferred to be an assertion is subject to the application of the hearsay rule.

R. v. Okemow, 2019 MBCA Whereas an adverse witness is a witness who is opposed in interest or position to the party calling that witness, a hostile witness is one who demonstrates an antagonistic attitude or hostile mind towards the party calling him or her.

R. v. Ryon, 2019 ABCA The jury must be instructed sufficiently to understand that its mere rejection of the accuseds testimony or other exculpatory evidence is not proof of the accu
