The Alcohol and Gaming Commission of Ontario proposed to revoke the respondent's liquor licence.
The respondent moved to stay the hearing, alleging witness tampering by an employee of the appellant.
The appellant retained a private investigator to interview witnesses.
The respondent sought a summons for the investigator to testify and produce interview records.
The Board refused, citing irrelevance.
The Divisional Court overturned the Board's decision, finding a breach of natural justice.
The Court of Appeal dismissed the appellant's appeal, holding that the investigator's evidence was material to the stay motion, the judicial review application was not premature due to the denial of natural justice, and the evidence was not protected by solicitor-client or litigation privilege.
