Queensland’s Criminal Code
To substantiate a murder charge, the greatest thing the Prosecution must prove, is intent to kill or do grievous bodily harm of such an extent that the person would die from their injuries if not treated. There are a number of defences available to the accused such as accident, self-defence, provocation, sudden or extraordinary emergency, insanity and diminished responsibility.
The Prosecutor is the best person to explain these terms to you, and to give you an idea of whether the Defence may attempt to call upon a particular strategy.
