If the discretion exercised by the President and the Minister under sections 8 and 10 was subjective, the court could not assess whether the powers conferred on the President and the Minister by sections 8 and 10 were exercised legally. The applicant had the burden of proof of showing that her detention was unlawful as the respondents had adduced a valid detention order and evidence of the President's subjective satisfaction that she should be detained.
