The police obtained a defective warrant to search the appellant's house for drugs.
They executed the search using excessive force, breaking down the door with a battering ram without prior warning.
No drugs were found, but weapons were seized.
The trial judge excluded the evidence under s. 24(2) of the Charter and acquitted the appellant.
The Court of Appeal ordered a new trial.
The Supreme Court of Canada allowed the appeal and restored the acquittal, holding that the search violated s. 8 of the Charter and that admitting the evidence would bring the administration of justice into disrepute due to the serious defects in the warrant and the excessive force used.
