"4. 1° No citizen shall be deprived of his personal liberty save in accordance with law. 2° Upon complaint being made by or on behalf of any person to the High Court or any judge thereof alleging that such person is being unlawfully detained, the High Court and any and every judge thereof to whom such complaint is made shall forthwith enquire into the said complaint and may order the person in whose custody such person is detained to produce the body of such person before the High Court on a named day and to certify in writing the grounds of his detention, and the High Court shall, upon the body of such person being produced before that Court and after giving the person in whose custody he is detained an opportunity of justifying the detention, order the release of such person from such detention unless satisfied that he is being detained in accordance with the law. 3° Where the body of a person alleged to be unlawfully detained is produced before the High Court in pursuance of an order in that behalf made under this section and that Court is satisfied that such person is being detained in accordance with a law but that such law is invalid having regard to the provisions of this Constitution, the High Court shall refer the question of the validity of such law to the Supreme Court by way of case stated and may, at the time of such reference or at any time thereafter, allow the said person to be at liberty on such bail and subject to such conditions as the High Court shall fix until the Supreme Court has determined the question so referred to it. 4° The High Court before which the body of a person alleged to be unlawfully detained is to be produced in pursuance of an order in that behalf made under this section shall, if the President of the High Court or, if he is not available, the senior judge of that Court who is available so directs in respect of any particular case, consist of three judges and shall, in every other case, consist of one judge only. 5° Nothing in this section, however, shall be invoked to prohibit, control, or interfere with any act of the Defence Forces during the existence of a state of war or armed rebellion. 6° Provision may be made by law for the refusal of bail by a court to a person charged with a serious offence where it is reasonably considered necessary to prevent the commission of a serious offence by that person."
