The communication referred to the alleged arbitrary detention of six activists and to the alleged use of torture for the purpose of extracting confessions. The Special Rapporteur expresses serious concern that the activists were subjected to torture and ill-treatment and denied adequate medical treatment for their injuries while in detention. In this context, the Special Rapporteur reiterates that Paragraph 7b of Human Rights Council Resolution 16/23 that urges States “[t]o take persistent, determined and effective measures to have all allegations of torture or other cruel, inhuman or degrading treatment or punishment promptly and impartially examined by the competent national authority, as well as whenever there is reasonable ground to believe that such an act has been committed; to hold persons who encourage, order, tolerate or perpetrate such acts responsible, to have them brought to justice and punished in a manner commensurate with the gravity of the offence, including the officials in charge of the place of detention where the prohibited act is found to have been committed; and to take note, in this respect, of the Principles on the Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (the Istanbul Principles) as a useful tool in efforts to combat torture.” In the absence of evidence to the contrary, the Special Rapporteur concludes that the six activists‟ rights under international law related to torture have been violated. The Special Rapporteur stresses that any evidence obtained through means of torture shall not be used in judicial proceedings. He calls on the Government to undertake a prompt and impartial investigation of those responsible for using such methods, leading to prosecution and punishment of the perpetrators, and to provide full redress to the victims.
