The appellant, an inmate, was disciplined with solitary confinement for assaulting another inmate.
He was subsequently charged under the Criminal Code for the same assault.
The appellant argued that the criminal trial violated his right against double jeopardy under s. 11(h) of the Charter.
The Supreme Court of Canada held that the prison disciplinary proceedings were not criminal in nature and did not impose true penal consequences.
Therefore, the criminal prosecution did not violate s. 11(h) of the Charter.
