the amendments did not deprive her of the right to judicial review of the legality, rationality and constitutionality of her detention and, in the alternative, if they did, the amendments were unconstitutional. High Court judgment Exclusion of judicial review Before the High Court, counsel for Teo, Anthony Lester Q.C., sought judicial review of the acts and decisions of the President or the Minister for Home Affairs which were purported to have been exercised under the powers conferred by section 8 of the ISA, submitting that the powers had been used for improper purposes, and in a manner which was illegal, irrational and unconstitutional. He also argued that since the Minister and the President, acting on advice of the Cabinet, had acted in bad faith and for improper purposes, they had acted outside the scope of the powers conferred by the ISA. Hence, the acts and decisions were null and void. Justice Frederick Arthur Chua ruled that the amendments to Article 149 and to the ISA did have the effect of depriving the applicant of her right to judicial review of the legality, rationality and constitutionality of her detention under the ISA. The court observed that the Court of Appeal in Chng Suan Tze had allowed the appeal solely on a technical ground – that the respondents had not adduced sufficient evidence of the President's satisfaction. Other matters mentioned in that judgment were merely obiter dicta. Therefore, although it had been held in Chng Suan Tze that the President's satisfaction under section 8(1) of the ISA was objective and thus reviewable by the court, these observations did not apply to the present proceedings in the light of the new provisions in the ISA. Section 8B(1), which stated that the law governing the judicial review of any decision made or act done in pursuance of any power conferred upon the President or the Minister by the Act shall be the same as was applicable and declared in Singapore on 13 July 1971, reaffirmed the law governing judicial review as laid down in the High Court's 1971 decision Lee Mau Seng v. Minister for Home Affairs, which was rendered on that date. Thus, the section had the effect of making a subjective test applicable to the exercise of powers under sections 8 and 10 of the ISA. Section 8B(2) provided that there was to be judicial review only in regard to any question
