Notable cases
Justice Miles dealt with many interesting cases during his career. An often cited and legally significant case is that of R v Hollingshed. This case involved the interpretation of Australia’s obligations under an international treaty when it had not been applied by law into Australia as affecting the treatment of a prisoner. He embarked on a full and frank discussion of the New South Wales prison system. Whilst he held that the treaty could be used to interpret the criminal law, he declined to hold that being held in “isolated protective custody” was unlawful under international obligations. Miles dealt with a claim for compensation for injuries suffered by a female complainant slipping on the floor at a supermarket. The complainant, aged 58, alleged that she had been deprived from potentially earning an income as a prostitute at a brothel. The complainant produced a number of young men who were prepared to testify that they were disappointed that the complainant had not been available as a prostitute. Miles declined to award any damages. Miles led an inquiry into the fitness to be tried of David Harold Eastman. Eastman had been sentenced to life imprisonment for the shooting of Colin Winchester, an Assistant Commissioner of Police, outside his Canberra home in 1989. Eastman had earlier lost appeals to the Federal Court and the High Court of Australia from his conviction. After hearing evidence at the inquiry for over two years, Miles presented his report to the Australian Capital Territory Government. He concluded that Eastman was fit to plead to the indictment.
