BTH v Tasmania

The applicant, BTH, appealed his conviction for rape to the Supreme Court of Tasmania. The appeal was brought on the grounds of alleged incompetence of his defence counsel, arguing that this incompetence resulted in a substantial miscarriage of justice and deprived him of a fair trial. The prosecution's case at trial was described as strong, while the defence's primary argument was that the sexual intercourse was consensual.

The central legal issue before the Full Court was whether the conduct of the applicant's trial counsel amounted to such incompetence as to occasion a substantial miscarriage of justice, thereby entitling the applicant to a new trial. This required the Court to assess whether the alleged failures of counsel were so significant that the trial could not be considered fair, notwithstanding the strength of the evidence against the applicant.

The Court considered the specific allegations of counsel's failures, including the failure to adduce certain evidence. It applied the principles governing appeals based on the incompetence of legal representation, which generally require a high threshold to be met. The Court would have had to determine if the alleged deficiencies in the defence strategy or conduct were so profound that they undermined the integrity of the trial process and prejudiced the applicant's ability to receive a fair hearing, considering the overall evidence presented.
