A number of regional human rights treaties have also been developed within the Council of Europe (CoE), the Organisation of American States (OAS) and the African Union (AU). The rights protected by these treaties derive from, and are similar to, those of the Universal Declaration of Human Rights, but each treaty has developed unique approaches when seeking to implement them. The principal instruments referred to here are:
- the European Convention on Human Rights
- the European Convention for the Prevention of Torture and Inhuman and Degrading Treatment or Punishment
- the American Convention on Human Rights
- the Inter-American Convention to Prevent and Punish Torture
- the African Charter on Human and Peoples’ Rights.
The European Court of Human Rights, the Inter-American Commission on Human Rights, the Inter-American Court of Human Rights, the African Commission on Human Rights and the (soon to be established) African Court on Human Rights are responsible for monitoring state-compliance with their respective treaties. These bodies examine allegations of torture on the same level as other alleged human rights violations. However, the CoE has also created a specific body for preventing torture in its member states.
The European Committee for the Prevention of Torture (CPT) was set up under the 1987 Council of Europe European Convention for the Prevention of Torture and Inhuman and Degrading Treatment or Punishment. It is composed of as many independent and impartial members as there are states parties to the Convention and may be assisted by ad hoc experts. Currently all members of the CoE have also ratified the European Convention for the Prevention of Torture. The CPT conducts periodic and ad hoc visits in any places under the jurisdiction of a contracting state where persons are deprived of their liberty by a public authority. States parties are obliged to provide the CPT with access to its territory and the right to travel without restriction; full information on the places where persons deprived of their liberty are being held; unlimited access to any place where persons are deprived of their liberty, including the right to move inside such places without restriction; and other information which is necessary for the CPT to carry out its task. The CPT is also entitled to interview, in private, persons deprived of their liberty and to communicate freely with anyone whom it believes can supply relevant information. The report on the visit and detailed recommendations sent to the government are confidential unless the government concerned decides that they can be published. In practise, most reports have been made public.
