A/HRC/30/37 before a court under counter-terrorism measures, emergency legislation or drug-related policies. 29. A State that detains a person in a situation of armed conflict as properly characterized under international humanitarian law, or in other circumstances of public danger or other emergency that threatens the independence or security of a State, has by definition that person within its effective control, and thus within its jurisdiction, and shall therefore guarantee the exercise of the right of the detainee to bring proceedings before a court to challenge the arbitrariness or lawfulness of the deprivation of liberty and to receive without delay appropriate and accessible remedies. Reconsideration, appeal or periodic review of decisions to intern or place in assigned residence alien civilians in the territory of a party to an international armed conflict, or civilians in an occupied territory, shall comply with the present Basic Principles and Guidelines, including Basic Principle 6 on the court as reviewing body. 30. Prisoners of war should be entitled to bring proceedings before a court to challenge the arbitrariness and lawfulness of the deprivation of liberty and to receive without delay appropriate and accessible remedies, where the detainee (a) challenges his or her status as a prisoner of war; (b) claims to be entitled to repatriation or transfer to a neutral State if seriously injured or ill; or (c) claims not to have been released or repatriated without delay following the cessation of active hostilities. 31. Administrative detention or internment in the context of a non-international armed conflict may only be permitted in times of public emergency threatening the life of the nation and the existence of which is officially proclaimed. Any consequent deviation from procedural elements of the right to bring proceedings before a court to challenge the arbitrariness and lawfulness of the deprivation of liberty and to receive without delay appropriate and accessible remedies must be in conformity with the present Basic Principles and Guidelines, including on the principles of non-derogability, the right to be informed and the court as reviewing body, and the guidelines on equality of arms and burden of proof. 32. During armed conflict, the deprivation of the liberty of children must only be a measure of last resort and for the shortest period of time. Basic legal safeguards must be provided in all circumstances, including for children deprived of liberty for their protection or rehabilitation, particularly if detained by military or security services. Safeguards include the right to legal assistance and a periodic review of the legality of the deprivation of their liberty by a court. The child has the right to have the deprivation of liberty acknowledged by the authorities and to communicate with relatives and friends.
