Procedural Posture

Criminal / Appeal From Acquittals Following Charter Rulings (court of Appeal)

  1. 1 Whether the DNA warrant was supported by reasonable and probable grounds that the respondent was a party to the offences
  2. 2 Whether the trial judge applied the correct standard of review in assessing the issuing judge's decision to grant the DNA warrant
  3. 3 Whether the exclusion of DNA evidence under s.24(2) was properly decided (note: appellate decision disposed without addressing s.24(2))

Ratio Decidendi

The Court of Appeal found the trial judge erred in law by misapplying the standard of review for warrants and evaluating the ITO piecemeal; when the ITO is considered as excised and amplified the combined DNA matches across scenes, the fingerprint in the stolen vehicle, and corroborative surveillance and seized items constituted sufficient credible and reliable evidence upon which an issuing judge could reasonably have been satisfied there were reasonable and probable grounds to issue the DNA warrant. The quashing of the DNA warrant was therefore overturned and a new trial ordered on counts 1, 4, 5 and 10.
