A/HRC/10/21 page 24 ill-treatment. The purpose of such recommendations is to effectively prevent instances of coerced confessions from occurring and to ensure that they will not be admitted as evidence in courts during criminal trials. 70. Such measures have far-reaching implications, for example, with respect to the right to privacy of the suspect, to the possibility of abuses when used during confidential meetings between defence counsel and clients, or to costs in relation to effectiveness, also with a view to different designs such measures may take. The Working Group feels that the issue warrants further study and calls upon Governments and other stakeholders to provide the Working Group with relevant information and share experiences made. IV. CONCLUSIONS 71. The Working Group, in the fulfilment of its mandate, welcomes the cooperation it has received from States, with regard to the responses by the Governments concerned concerning cases brought to their attention. During 2008, the Working Group adopted 46 Opinions concerning 183 persons in 22 countries. 72. The Working Group welcomes the invitations extended to it as well as the cooperation on the part of Governments. The Working Group conducted four official visits in 2008, to Colombia, Italy, Mauritania and Ukraine. Among all the requested country visits, the Working Group has received invitations by the Governments of Malta, Senegal and the United States of America. The Working Group reiterates its belief that its country visits are essential in fulfilling its mandate. For Governments, these visits provide an excellent opportunity to show developments and progress in detainees’ rights and the respect for human rights, including the crucial right not to be arbitrarily deprived of liberty. Further to this, the Working Group considers that future visits and follow-up visits are of utmost importance. 73. The Working Group considers the question of detention in the context of counter-terrorism. As such, the Working Group considers it necessary to reiterate the prominent concern that, in the counter-terrorism context, some States continue to use deprivation of liberty without charges or trial or other applicable procedural guarantees against persons accused of terrorist acts; a practice the Group considers as contrary to international human rights instruments. Specifically, the Working Group considers that detained persons suspected of terrorist activities and/or acts shall be immediately informed of such charges in line with relevant national legislation; they shall be brought before a competent judicial authority; and they shall enjoy the effective right to habeas corpus. The Working Group deems it appropriate to put forward a list of principles in conformity with articles 9 and 10 of the Universal Declaration of Human Rights, and articles 9 and 14 of the International Covenant on Civil and Political Rights, which may be used in the context of measures countering terrorism. 74. The Working Group considers that, among other factors, corruption is detrimental to the rule of law and on the effective fulfilment of human rights, including the right to be free from arbitrary detention.
