The appellant appealed a conviction for driving with excess alcohol, arguing that the police lacked reasonable and probable grounds for arrest, leading to a breach of Charter rights (ss. 7, 8, 9).
The trial judge found the arrest lawful despite contradictory police testimony regarding subjective grounds.
On appeal, the court found the arrest unlawful due to the absence of subjective reasonable and probable grounds by the directing officer, which invalidated the arresting officer's actions.
Consequently, the breath samples obtained were deemed to be in breach of Charter rights.
Applying the s. 24(2) Grant factors, the court determined that the police conduct was serious and had a significant impact on the accused's rights, outweighing society's interest in adjudication on the merits.
The evidence was excluded, leading to an acquittal.
A secondary issue regarding s. 11(b) Charter rights was declined due to lack of timely objection at trial.
