Abstract

This paper reports the first case in which a linguist served as an expert witness in Hong Kong, a former British colony that has operated as a special administrative region of the People’s Republic of China (PRC) since 1997. The dispute was on the meaning of the political slogan “Liberate Hong Kong, Revolution of Our Times”, which was widely adopted during the 2019–2020 protests. The keywords “liberate” and “revolution” are smoking gun evidence for the prosecution in a large cluster of cases that involve sedition law and national security offences. Section I of the paper provides background information about a case the author was involved in, which was concerned with whether the slogan was seditious. Section II describes the analysis conducted, which concludes that the slogan as a whole refers to a need to rectify a problem and to return to the original, a more desirable state of affairs for Hong Kong, without specifying what problem there is and what the desirable state of affairs looks like. Section III highlights some critical issues in the analysis, discussing challenges faced and ethical questions for the expert witness. Section IV is a postscript that briefly describes the outcome of the case.
