DPP v Parker

In the matter of the Director of Public Prosecutions versus Parker, the High Court was asked to determine the appropriate legal test to apply when assessing whether a belief in the necessity to commit a crime under duress was reasonable. The accused, Parker, was charged with murder but raised a defence of duress, claiming he acted under threat of imminent death or serious injury. The legal question before the Court was whether the test for the reasonableness of the belief in necessity is objective, subjective, or a combination of both, particularly in light of amendments to the Crimes Act 1958.

The Court was required to interpret the meaning of 'reasonable belief' in section 9AG of the Crimes Act, specifically subsections (2)(a) to (c), and whether the amendment by the Crimes Amendment (Abolition of Defensive Homicide) Act 2014 had altered the established legal test. The Court also considered the relevance of section 322O of the amending Act to the construction of section 9AG(2). Additionally, the Court examined whether the assessment of a 'reasonable' belief should be made by reference to a reasonable person who possesses the personal characteristics of the accused that might have affected the accused’s appreciation of the circumstances.

The Court concluded that the test for the reasonableness of a belief in the necessity to commit a crime under duress should be partially objective and partially subjective. It held that the test involves assessing whether the conduct was a reasonable response to the threat as perceived by a reasonable person, considering the personal characteristics of the accused that might have affected their perception of the threat. The Court further found that the amendment by the 2014 Act did not alter the established test and that section 322O of that Act did not affect the interpretation of section 9AG(2). The Court's reasoning was based on the need to balance the objective standard of a reasonable person with the subjective influences of the accused's personal characteristics.

The final orders of the Court included a direction for the Court of Appeal to apply the partially objective and partially subjective test as outlined in its judgment. The Court clarified that in assessing the reasonableness of the accused's belief, the circumstances must be evaluated from the perspective of a reasonable person with the personal characteristics of the accused. The Court also directed that any further proceedings should take into account the specific factors and personal circumstances of the accused, ensuring a fair and just application of the duress defence in the context of homicide charges.
