The appellant broke into the complainant's apartment and assaulted her while heavily intoxicated.
He was acquitted at trial on the basis that his self-induced intoxication raised a reasonable doubt as to his intent.
The Court of Appeal overturned the acquittal, holding that breaking and entering and committing an assault is an offence of general intent to which the defence of drunkenness does not apply.
The Supreme Court of Canada dismissed the appeal, affirming that the offence is one of general intent and the rule in Leary applies.
