and not innocence. He added: "It is for the courts, and the courts alone, to exercise judicial power and decide the question of guilt, in a trial." With effect from 20 May 2008, Woon was appointed a director of the Monetary Authority of Singapore. He also served on the Presidential Council for Minority Rights between 2008 and 2010. Woon was the first Attorney-General in more than ten years to personally appear in court. On 28 July 2008, he argued before the Court of Appeal that a woman, 24-year-old Aniza bte Essa, who had manipulated her 17-year-old teenage lover Muhammad Nasir bin Abdul Aziz into killing her husband should be given a life sentence. The Court held that life imprisonment was inappropriate due to the defendant's psychiatric condition, and affirmed the nine-year jail term imposed by the High Court. Nasir was detained indefinitely at the President's Pleasure for murder instead of receiving the death sentence as he was below 18 years old at the time he killed Manap bin Sarlip (Aniza's husband) and thus cannot be sentenced to hang under Singapore law. Woon elected to take proceedings against Tang Wee Sung, chairman of the company C.K. Tang which owns Tangs department store, for the illegal purchase of a human organ – a kidney – in the first case of its kind in Singapore. The decision to do so was criticised by Dr. Lee Wei Ling, Director of the National Neuroscience Institute and daughter of Minister Mentor and former Prime Minister Lee Kuan Yew, in an article published in The Straits Times on 5 September 2008. Woon replied, pointing out a number of misconceptions she held as to the facts and the law, and emphasising that the prosecution had been brought as no one was above the law. Subsequently, in response to further comments by Dr. Lee, he wrote an extended article entitled "Wrong Facts and Faulty Logic" that appeared in The Straits Times on 18 September 2008. He also prosecuted a number of contempt of court cases, including suits against Dow Jones Publishing Company (Asia), Inc. for material published in The Wall Street Journal Asia; against US-based lawyer Gopalan Nair for comments on his blog; and against three Singapore Democratic Party supporters, John Tan Liang Joo, Isrizal bin Mohamed Isa and Muhammad Syahmi bin Sariman, who wore T-shirts bearing the image of a kangaroo dressed in a judge's gown outside the
