The Crown appealed the dismissal of charges under the Occupational Health and Safety Act against an employer and supervisor following a workplace accident.
The lower courts had excluded evidence from the Ministry of Labour's inspection of a roller, finding a breach of the respondents' Charter rights (s. 11(d)) due to the inspectors' failure to halt inspection after a lawyer's letter, poor note-taking, and not following internal policies.
The Court of Appeal found that there is no constitutional right for an accused to direct an investigation or be present during evidence inspection.
It held that inconsistencies in inspector testimony or failure to follow internal guidelines do not amount to a Charter violation.
Crucially, the respondents failed to demonstrate any prejudice to their right to make full answer and defence, especially after disposing of the evidence themselves.
The appeal was allowed, and a new trial ordered.
