Kivi Bar Wari pleaded guilty to the manslaughter of his cellmate.
Crown and Defence jointly recommended an eight-year sentence, which the court accepted.
The primary outstanding issue was the calculation of pre-sentence custody credit.
The Crown argued for standard 1.5:1 Summers credit, while the Defence sought additional enhanced Duncan credit due to unduly harsh detention conditions during the COVID-19 pandemic.
The court, following R. v. Marshall, held that Duncan credit is a mitigating factor to be considered when determining the appropriate sentence, not an additional deduction after the sentence is set.
Since the joint sentencing submission had already factored in the harsh conditions, granting further enhanced credit would constitute "double accounting." The court applied the 1.5:1 Summers credit to the remaining pre-sentence custody.
