Boyson v Chief of Army

In the case of Boyson v Chief of Army, the applicant sought an extension of time to appeal his conviction by a General Court Martial, where he was found guilty of sexual intercourse without consent. The court had to determine whether the General Court Martial’s verdict was unreasonable and not supported by the evidence, and whether it was unsafe or unsatisfactory. The complainant had alleged that the applicant inserted a bottle into his rectum while he was sitting up. However, the prosecution's case relied on alleged admissions by the applicant, with no direct witnesses to the insertion incident. The applicant had admitted placing a bottle between the complainant's thighs but denied inserting it into his anus. The court found that the physical improbability of the alleged act, absence of corroborative evidence from other witnesses, and the availability of an innocent explanation for the alleged admissions undermined the prosecution's case. Consequently, the court granted the extension of time, allowed the appeal, and quashed the conviction.

The key legal issue was whether the General Court Martial’s verdict was open on the whole of the evidence, considering the alleged act's physical impossibility and the lack of corroborative evidence. The court examined the complainant's evidence, the video footage, and the testimonies of the witnesses. The absence of corroborative evidence from the other officers present in the bathroom at the time of the alleged incident was significant, as it was improbable that no one would have observed or noticed the act or its immediate aftermath. Additionally, the appellant's account of placing the bottle between the complainant's thighs was corroborated by one of the witnesses, Captain Machatsch. The court held that the prosecution's case failed to prove the appellant's guilt beyond reasonable doubt due to the high degree of improbability of the alleged act and the lack of corroborative evidence.
