Q: Question: Who was the main author of the Magna Carta? Passage:During the 24 November 1999 Parliamentary debate on the rule of law, Jeyaretnam traced the doctrine to the Magna Carta, and said that it was to be found in the Constitution of Singapore, particularly in Article 9 and Article 12, which respectively protect the rights to life and personal liberty, and equality rights. He also noted that in the court judgment Ong Ah Chuan v Public Prosecutor (1980), the Privy Council had held that in phrases such as "in accordance with law" and "equality before the law" in the Constitution, the term law does not only mean Acts passed by Parliament, but also includes the fundamental rules of natural justice that have been accepted and become part and parcel of the common law. He then cited eight instances of the Government's alleged non-compliance with the rule of law, including detention without trial under, inter alia, the ISA and the Criminal Law (Temporary Provisions) Act ("CLTPA"); denial of the right of arrested persons to counsel and to visits from their families for a period of time; denial of the rights to freedom of speech and assembly; and the tendency of the executive not to provide reasons for decisions made. Opposition MP Chiam See Tong complained that the Government had not treated opposition parties fairly as regards applications for licences for events.
