The appellant argued that the observations of slurred speech were made before the appellant was provided his rights under 10(b), and like the statements made by the accused the observations of the manner of his speech should also be excluded. While statements made by the accused are inadmissible, a physical manifestation such as slurred speech can be introduced to prove impairment. R. v. Rodgers, 2011 SKQB 244, [2011] S.J. No. 403
