Rafael Hui Si-yan

Rafael Hui Si-Yan, born in 1948, is a former Chief Secretary for Administration of Hong Kong and a former career civil servant. Hui was arrested in March 2012 by the Independent Commission Against Corruption on suspicion of corruption. The trial of Hui, along with Sun Hung Kai Properties co-chairmen Thomas Kwok Ping-kwong and Raymond Kwok Ping-luen, which opened in early June 2014, has since been called the most high-profile corruption trial in the history of the Hong Kong SAR.
