The accused, a police officer, was charged with attempting to purchase the sexual services of a person under 18.
During the investigation, he made a statement to police without being informed of his right to counsel.
The trial judge excluded the statement from the Crown's case in chief under s. 24(2) of the Charter.
When the accused testified at trial, the Crown sought to use the excluded statement to impeach his credibility during cross-examination.
The trial judge refused, and the accused was acquitted.
The Supreme Court of Canada dismissed the Crown's appeal, holding that the proposed use of the statement for impeachment was not a material change of circumstances that warranted reconsidering the initial ruling that its admission would bring the administration of justice into disrepute.
