Howieson v Chief of Army

In Howieson v Chief of Army, the appellant, Captain Howieson, was found guilty of prejudicial conduct by a General Court Martial under s 60(1) of the Defence Force Discipline Act 1982 (Cth). The court was tasked with determining whether there was a material irregularity in the proceedings that led to a substantial miscarriage of justice under s 23(1)(c) of the Defence Force Discipline Appeals Act 1955 (Cth). The primary issue was whether the admission of tendency evidence, which was later deemed inadmissible, and the timing of the directed acquittal on one charge, prejudiced Captain Howieson's right to a fair trial.

The court found that the panel was exposed to highly prejudicial evidence that had a tendency to induce subconscious bias against Captain Howieson. This was accentuated by the timing of the directed acquittal, which occurred after the prejudicial evidence was presented but before Captain Howieson could refute the allegations and call corroborative evidence. The court concluded that there was a real possibility that Captain Howieson might have been acquitted if the prejudicial evidence had not been adduced or if he had the opportunity to refute it and enhance his credibility. Consequently, the court determined that there was a substantial miscarriage of justice.

The court allowed the appeal and ordered a new trial for the charge in question, quashing the conviction and setting aside the dependent sentence. The decision underscored the importance of a fair trial and the right of an accused not to be deprived of a real possibility of acquittal due to procedural irregularities. The court also highlighted the significance of reviewing officer reports in provoking thoughtful consideration of legal issues and evidence summaries.
