What the Prosecution Needs to Prove (Elements of the Offence)

To secure a conviction for a PCA offence, the prosecution must prove beyond reasonable doubt the following elements:

  1. Identity of the Driver: That the person charged was the driver of the vehicle.
  2. Driving on a Public Road: That the driving occurred on a public road or a place to which the public has access.  The definition of a road can vary depending on the circumstances, so it is important to speak to a lawyer to determine whether you have a defence. 
  3. Presence of Alcohol: The driver had a blood alcohol concentration (BAC) at or above the prescribed limit. This is typically proven through a breathalyzer test or blood test.
The Relevant Court

PCA offences are generally heard in the Magistrates Court of South Australia. 

What Defences are Available

Several defences can be raised in response to a PCA charge, including:

  1. Challenging the Accuracy of the breath analysis: The device must be in proper working order and properly operated, if it is not, questions may be raised about the accuracy of the result. 
  2. Challenging the legality of the test: The police must follow procedures to ensure they have authority to conduct the test and advise you of your rights in relation to the test. If they do not this could be a defence to the charge depending on the extent of the breach. 
What are the Specific Maximum Penalties for the Offence
