POLICE v TULLY
[2011] SASC 242

Magistrates Appeal

GRAY J:

  1. This is an appeal against the dismissal of a complaint. 

  2. The defendant and respondent, Peter George Tully, was charged with driving a motor vehicle on a road while there was present in his blood the prescribed concentration of alcohol as defined in section 47A of the Road Traffic Act 1961 (SA) in contravention of section 47B(1)(a) of the Road Traffic Act.  It was alleged that this occurred on 5 June 2010 and that the concentration of alcohol was .086 grams in 100 millilitres of blood. 

  3. The defendant pleaded not guilty.  The trial proceeded in the Adelaide Magistrates Court.  The prosecution led evidence from a police officer who stopped the defendant, administered an alcotest and who later administered the breath analysis test.  There was no challenge to this testimony.  There was no suggestion that the alcotest or breath analysis test were conducted other than in accordance with correct processes and procedures.  It was accepted that the prosecution had made out a case to answer. 

  4. The defence case was that on the balance of probabilities it had been established that the blood alcohol reading disclosed by the breath analysis testing was exaggerated. In that circumstance, it was said that the reading was unreliable and that as a consequence the prosecution were unable to establish that at the time of driving the defendant did so with a prescribed concentration of alcohol in his blood.  The defendant gave evidence, tendered analysis certificates and called a forensic scientist, the manager of the toxicology section of Forensic Science SA, Peter Felgate, to give expert evidence as to the analysis of a sample of the defendant’s blood taken at a hospital later that day. 

  5. Before coming to discuss the evidence, it is convenient…

CaseChat Overview and Summary

The Police sought to appeal against the decision of a Magistrate who dismissed a complaint against the defendant, Tully, who was charged with driving a motor vehicle on a road while there was present in his blood the prescribed concentration of alcohol, contrary to section 47B(1)(a) of the Road Traffic Act 1961 (SA). The specific charge related to a blood alcohol concentration of 0.086 grams of alcohol in 100 millilitres of blood. The central legal issue was whether the evidence demonstrated that the breath analysis testing, which gave the blood alcohol reading, provided an exaggerated result. The court was required to determine if the Magistrate's decision to dismiss the complaint was appropriate, given the evidence presented regarding the accuracy of the breath analysis test.

The court considered the evidence and arguments presented by both parties. The police argued that the blood alcohol reading was accurate and that the Magistrate should have convicted the defendant. In contrast, the defendant contended that the breath analysis instrument provided an exaggerated reading. The court examined the evidence and concluded that it did not substantiate the claim that the breath analysis instrument provided an exaggerated reading. The court held that the Magistrate's decision to dismiss the complaint was erroneous, as the evidence did not support the defendant's argument that the breath analysis result was exaggerated.

The appeal was allowed, and the orders of the Magistrate were set aside. The court found that the evidence did not demonstrate that the breath analysis testing was exaggerated. Consequently, the defendant was convicted of the offence of driving a motor vehicle on a road while there was the prescribed concentration of alcohol in his blood. The court ordered that the defendant be convicted of the offence, with a specific concentration of 0.086 grams of alcohol in 100 millilitres of blood. Additionally, the orders of the Magistrate, including the order as to costs, were set aside.
