Historical Sexual Assault Conviction Overturned

In, R v. H., 2016 ONCA 85, the Ontario Court of Appeal allowed an appeal from conviction for sexual assault. The key aspect of the decision concerns the trial judge’s use of the Appellant’s demeanour while testifying.   Justice Epstein, writing for the Court, had some interesting things to say about the proper use of demeanour evidence in criminal trials and cautioned trial judges about over-reliance on it:

[44]       This court has repeatedly cautioned against giving undue weight to demeanour evidence because of its fallibility as a predictor of the accuracy of a witness’s testimony: Law Society of Upper Canada v. Neinstein, 2010 ONCA 193, 99 O.R. (3d) 1, at para. 66; R. v. Rhayel, 2015 ONCA 377, 324 C.C.C. (3d) 362. As I indicated in Rhayel, at para. 85, “[i]t is now acknowledged that demeanour is of limited value because it can be affected by many factors including the culture of the witness, stereotypical attitudes, and the artificiality of and pressures associated with a courtroom.”

[45]       Although the law is well settled that a trial judge is entitled to consider demeanour in assessing the credibility of witnesses, reliance on demeanour must be approached cautiously: see R. v. S. (N.), 2012 SCC 72, [2012] 3 S.C.R. 726, at paras. 18 and 26. Of significance in this case is the further principle that a witness’s demeanour cannot become the exclusive determinant of his or her credibility or of the reliability of his or her evidence: R. v. A. (A.), 2015 ONCA 558, 327 C.C.C. (3d) 377, at para. 131; R. v. Norman (1993), 16 O.R. (3d) 295 (C.A.), at pp. 313-14.

Zachary Kerbel represented the Appellant in the appeal.   The judgment can be found here.

Motherisk Child Protection Cases to be Reviewed by Retired Judge

Retired Family Court Judge Judith Beaman will lead a commission into thousands of cases where Motherisk’s forensic analyses were used in child protection cases.   Motherisk’s drug and alcohol testing policies were recently found to be “inadequate and unreliable” on an independent review conducted by retired Ontario Court of Appeal judge, Susan Lang.

Justice Lang’s report can be found here.

The flawed forensic testing conducted by Motherisk’s labs was first uncovered in the case of R v. Broomfield, 2014 ONCA 725 (CanLII)

Saman Wickramasinghe was co-counsel to Ms. Broomfield on her appeal to the Ontario Court of Appeal.  The Court of Appeal’s judgment in her appeal can be found here.

The sentencing decision can be found here.

Michael Enright’s essay from CBC’s Morning Edition regarding the proceedings can be found here.

Saman Wickramasinghe was co-counsel to S.K. at his trial and sentencing.

Drunk Driving Convictions Overturned

In R v. B., 2015 ONSC 6901 (CanLII), the Ontario Superior Court of Justice overturned drinking and driving convictions based on the insufficiency of the trial judge’s reasons for judgment.  The trial judge had failed to make any findings of fact or credibility, and failed to resolve conflicting evidence on several material points.

Without making these findings, there was no way for the Appellant, or the reviewing court, to understand why he had been convicted.  A new trial was ordered.

Zachary Kerbel was counsel to the Appellant on the appeal.
