The Court of Appeal on Monday began hearing a challenge by Hong Kong’s former No.2 government official Rafael Hui Si-yan against his corruption conviction.

The 67-year-old former chief secretary was convicted of misconduct in public office last year in what was Hong Kong’s most high-profile corruption case before former chief executive Donald Tsang Yam-kuen was charged last month.

Hui was sentenced to seven and a half years in prison asked to return HK$11.182 million in bribes.

His briber, Thomas Kwok Ping-kwong, former co-chairman of the Sun Hung Kai Properties, is also appealing his conviction and five-year sentence.

Thomas Kwok and his brother Raymond were accused of paying Hui to be their eyes and ears in the government. Raymond Kwok was acquitted while his brother was jailed.

The Kwok family is one of the richest in Hong Kong and their Sun Hung Kai Properties is one of the largest real estate companies in Asia.

Former Sun Hung Kai executive director Thomas Chan Kui-yuen and businessman Francis Kwan Hung-sang were also jailed and are appealing their conviction and sentence.
