There again, those who believe in the absolute personal liberty of the individual will recognise that this power of preventive detention has been helped in by two limitations : one is that the Government shall have power to detain a person in custody under the provisions of clause (3) only for three months. If they want to detain him beyond three months they must be in possession of a report made by an advisory board which will examine the papers submitted by the executive and will probably also give an opportunity to the accused to represent his case and come to the conclusion that the detention is justifiable. It is only under that that the executive will be able to detain him for more than three months Secondly, detention may be extended beyond three months if Parliament makes a general law laying down in what class of cases the detention may exceed three months and state the period of such detention.
