Article 9 of the Constitution of Singapore states that:

An arrested person has the following rights guaranteed under the Constitution:

(1) to be deprived of his life or liberty only if according to law; 

(2) if the detention is unlawful, to apply to the High Court to secure release; 

(3) to be informed of the grounds of his arrest as soon as may be; 

(4) to be allowed to consult and be defended by a legal practitioner of his choice;

(5) if he is not released, he must without unreasonable delay and in any case within 48 hours (excluding the time for any necessary journey) be produced before a Magistrate who shall decide if he should be further detained.

List 3 examples of case laws in Singapore (one case for each particular right) or any existing Statutes (laws passed by Parliament) where it appears that such 3 rights were not guaranteed as stated in the Constitution. What (if any) recommendations would you make with regard to legal reform (i.e. making the law more just and fair)?
