Geoffrey Robert Tighe v The Queen

Geoffrey Robert Tighe, the appellant, sought to overturn his conviction on the grounds that the evidence used against him was unreliable and inconsistent. The case was heard in the High Court of Australia. The respondent, the Crown, defended the conviction, arguing the evidence was reliable and consistent. The core issue was whether the evidence presented was reliable and whether any inconsistencies were significant enough to warrant setting aside the conviction. The court had to determine if the inconsistencies between the evidence provided in the Local Court and the appellant's admissions in later proceedings were so substantial that they undermined the reliability of the evidence.

The High Court examined the nature and extent of the inconsistencies in the evidence. It noted that the appellant's evidence in the Local Court proceedings differed markedly from his admissions in later proceedings. The court considered whether these inconsistencies were due to the appellant's changing stance or whether they pointed to a fundamental unreliability in the evidence. The court also assessed whether these inconsistencies, if proven to be significant, would have led to a different outcome in the proceedings. The High Court concluded that the inconsistencies were not merely minor discrepancies but substantial enough to cast doubt on the reliability of the evidence.

Given the substantial inconsistencies, the High Court found that the evidence was unreliable to the extent that it could not support the conviction. The court held that the appellant's admissions in later proceedings, which contradicted the evidence given in the Local Court, were significant and affected the reliability of the evidence. Consequently, the High Court set aside the conviction. The court's decision emphasised the importance of reliable and consistent evidence in criminal proceedings, especially when it forms the basis of a conviction.
