A billionaire who jointly controls Asia 's biggest property development company and a former No . 2 official of Hong Kong were found guilty of conspiracy to commit misconduct in the city 's biggest corruption trial . The tycoon , Thomas Kwok along with his younger brother , Raymond Kwok were accused of bribing Rafael Hui , the government official , in offenses spanning nearly a decade . The Kwok brothers , who rank 86th on the 2014 Forbes list of the world 's richest people , are co-chairs of the developer giant Sun Hung Kai , which is responsible for many of Hong Kong 's most iconic skyscrapers . The main question during their trial was whether the brothers had bought the allegiance of Hui , Hong Kong 's former chief secretary . After five days of deliberation , a Hong Kong High Court jury found the older Kwok guilty of bribing Hui between 2005 and 2007 . Immediately after the verdict , Thomas Kwok resigned from his position at Sun Hung Kai , and his son , Adam Kwok was named the company 's next executive director . Meanwhile , his younger brother , Raymond Kwok was cleared of all charges . Hui is the highest-ranking former official to face trial in Hong Kong . The court looked into whether Hui received monetary and housing benefits worth at least $ 4.3 million from the Kwoks in return for government decisions favorable to the company . The charges related to accepting rent-free apartments , unsecured loans and a consultancy agreement with the property company . The jury found him guilty on three counts of misconduct in a public office , conspiracy to commit misconduct in public office and conspiracy to offer an advantage to a public servant . The jury also found Thomas Chan , who was responsible for land acquisition at the company and Francis Kwan , a former Hong Kong Stock Exchange official , guilty for making a series of payments to Hui . The sentencing hearing for the four who were convicted will be held Monday . Raymond Kwok was released from custody after his arrest in 2012 . As he left the court , Kwok said he had mixed feelings that he was free , but his brother had been found guilty . The case caused a media frenzy in the city , where real estate is a local obsession . Sun Hung Kai , which helped to build some of the tallest buildings in the city 's celebrated skyline , contributed to the Kwok brothers ' estimated $ 18.3 billion fortune . Hong Kong , a special administrative region of China , is considered to be one of the world 's least corrupt territories . According to Transparency International 's 2013 Corruptions Perceptions Index , Hong Kong is the 15th least corrupt territory in the world -- with the United States , by comparison , ranked 19th .
