The appellant appealed his convictions arising from an alleged domestic assault.
At trial, the judge sought corroboration for the complainant's testimony and relied on the opinion evidence of an investigating police officer regarding the complainant's demeanour and injuries, as well as the complainant's prior consistent statements to her daughter and police.
The Court of Appeal held that the officer's evidence improperly ventured into expert opinion and was used to shore up the complainant's credibility.
Furthermore, the prior consistent statements were improperly used for their truth.
The appeal was allowed, the convictions were set aside, and a new trial was ordered.
