Poon Siu-tung

In 2011, the trial of Stephen Chan Chi-wan in relation to the 2010 TVB corruption scandal took place in the District Court before Poon, who acquitted Chan and the co-defendants.[27] On appeal, in 2012 the Court of Appeal set aside the not guilty verdicts and remitted the case to Poon to consider if the defendants could rely on the defence of reasonable excuse.[28] In 2013, Poon ruled that the defendants could rely on such a defence and therefore dismissed the charges afresh.[29] On appeal, in 2015 the Court of Appeal once again allowed the appeal and directed Poon to convict Chan and his co-defendant (Tseng Pei Kun) on the charge of conspiring for an agent to accept an advantage and sentence them accordingly.[30] Poon subsequently sentenced Chan to a fine of HK$84,000 and Tseng to a fine of HK$28,000.[31] On further appeal, in 2017 the Court of Final Appeal overturned the decision of the Court of Appeal and re-instated Poon's original decision by quashing the defendants' convictions and acquitting them of all charges.[32]

In 2012, Poon heard a case in the District Court involving a Tuen Mun District Councillor who put up banners stating “Demand the Integrated Community Centre for Mental Wellness (ICCMW) to be relocated far away from Wu King Estate residents”. The plaintiff was a person with mental illness who argued that the Councillor had committed an act of disability vilification. Poon held that the banners incited hatred against people with disabilities, and ruled in favour of the plaintiff, whom he awarded nominal damages of HK$1.[33][34]

In 2013, Poon heard and dismissed an application by Lew Mon-hung in the District Court for a permanent stay of proceedings in respect of a charge of perverting the course of justice relating to a letter sent to the Chief Executive, Leung Chun-ying, and the Commissioner of the ICAC, Simon Peh, with a view to influence them to halt the ICAC's investigation against him.[35]
