Three inmates were charged with assault causing bodily harm to a fellow inmate at Maplehurst Correctional Centre on November 19, 2014.
The Crown sought to introduce video evidence of the assault with identification testimony from a correctional officer.
The court held a voir dire to determine the admissibility of the identification evidence under the Leaney test.
The court found that while the officer had prior acquaintance with the accused and was in a better position than the trier of fact to make identifications, the threshold reliability of the identification evidence was not established because the Crown relied on a Historical Unit Assignment document that was demonstrably inaccurate.
The document showed 35 inmates in a unit with a maximum capacity of 32, and showed inmates in cells where they were not actually housed.
Without reliable evidence of which inmates were assigned to which cells, the officer's identification methodology—tracking blurry figures back to assigned cells—could not meet the reliability threshold.
The charges were dismissed.
