This chapter discusses the protections afforded by international human rights law to the right to liberty and security of the person and the right to a fair trial. The right to liberty regulates powers of detention and provides safeguards against ill-treatment of detainees. An extreme form of arbitrary detention is enforced disappearance. The right to a fair trial sets out how court proceedings should be conducted and court systems organized. In addition, there are specific protections for those who are suspected of having committed a criminal offence.
