Pringle v Police

This matter concerned an appeal by Mr Pringle against his conviction for driving under the influence of a drug. The prosecution relied on several certificates tendered as evidence, including certificates relating to a drug screening test, the proper functioning of the testing apparatus, the collection of an oral fluid sample, and the analysis of that sample by an analyst at the Forensic Science South Australia (FSSA). Mr Pringle challenged the admissibility and evidentiary weight of these certificates, particularly Exhibit P5, which was the analyst's certificate.

The central legal issues before the Court were whether the Governor had the power to approve apparatus for collecting oral fluid samples, the extent to which Exhibit P5 purported to certify matters prior to the sample reaching the FSSA, whether the prosecution was entitled to rely on Exhibit P5 for the analysis conducted at the FSSA, and whether there were grounds to exercise a discretion to exclude Exhibit P5 due to unfairness. Additionally, the Court considered whether Exhibit P3, relating to the collection of the oral fluid sample, adequately encompassed the collection process and whether the police officer's evidence before the Magistrate sufficiently addressed the propriety of that process.

The Court held that the Governor had no power to approve apparatus for collecting oral fluid samples, and such approval was not required by the Road Traffic Act. It was determined that Exhibit P5 did not purport to certify any part of the process before the oral fluid sample arrived at the FSSA, and the prosecution only relied on it to certify the analysis performed at the FSSA. The Court found no circumstances warranting the exercise of the *Christie* discretion or a general unfairness discretion to exclude Exhibit P5. Furthermore, the Court concluded that Exhibit P3 was intended to cover the collection process, and in any event, the police officer's unchallenged evidence before the Magistrate addressed the propriety of the collection.

Consequently, the appeal was dismissed.
