Regina v Joshua Francis Green

In Regina v Joshua Francis Green, the appellant, Joshua Francis Green, stood trial in the Supreme Court of Queensland for the charge of attempted murder. The trial was initiated after Green was found to have engaged in conduct that would constitute an attempt to murder if he had been sane at the time of the offence. The defence argued that Green was suffering from a mental illness at the time of the events, rendering him not legally responsible for his actions. The central issue before the court was whether Green was suffering from a mental illness that negated his responsibility for the attempted murder.

The court was required to determine whether, at the time of the alleged offence, Green was suffering from a mental illness to such an extent that he was unable to understand the nature and quality of his act or to know that it was wrong. The onus was on the defence to prove this on the balance of probabilities. The court considered expert psychiatric evidence, which indicated that Green met the criteria for a severe mental illness, which impaired his ability to comprehend his actions or their wrongfulness. The court was tasked with weighing this evidence and deciding whether it met the required standard of proof.

After thorough consideration of the evidence, the court found that it was more likely than not that Green was suffering from a mental illness at the time of the offence. Consequently, the court determined that Green was not legally responsible for his actions due to his mental illness. The court returned a special verdict that Green was not guilty by reason of mental illness. The court concluded that the defence had successfully demonstrated that Green’s mental state precluded him from being held criminally liable for his conduct.
