Hong Kong Special Administrative Region Court of Appeal, HKSAR v Wun Shu Fai (2017)
“ Clearly, the affirmation permitted a line of cross-examination, by Mr McNamara of Jacky Ma, that he was motivated to secure a reduction in the sentence of imprisonment imposed on him on the basis that not only had he given a detailed statement to the police describing the conduct of other defendants but also he was prepared to testify against them, including the applicant. Also, it was relevant to the issue of whether or not he knew what range of discount to anticipate for having given evidence for the prosecution against an accomplice. ”
