2017 Singaporean presidential election
On 5 May 2017, Dr Tan Cheng Bock, a former Member of Parliament (MP) from the People's Action Party (PAP) who contested in the Singaporean presidential election of 2011, filed a constitutional challenge to determine whether it is correct to set the Presidential Election 2017 as a reserved election under the newly introduced amendments to the Elected Presidency. His challenge was dismissed by Justice Quentin Loh in High Court, explaining that "Article 164(1)(a) provides for Parliament to specify the first term of office of the President to be counted under Art 19B(1) ("First Term")." He then filed an appeal, heard by the Court of Appeal on 31 July 2017. On 23 August 2017, his appeal was unanimously dismissed by the court of five judges which ruled that the Parliament has full discretion to set the First Term.
