that any violation of Article 5(2) of the Convention necessarily results in the violation of Article 5(1) thereof.51 69. The Court will refer below to the following: (1) the alleged acts of torture and other cruel, inhuman and degrading treatment perpetrated against Mr. Fleury; (2) the conditions in which Mr. Fleury was detained, and (3) the alleged violation of the right to personal integrity to the detriment of Mr. Fleury’s family. The alleged non-compliance with the obligation to investigate these facts will be addressed in the chapter on the rights to judicial guarantees and judicial protection of Mr. Fleury and of his family. 1. The alleged acts of torture and other cruel, inhuman and degrading treatment perpetrated against Mr. Fleury 70. First, the Court reiterates its case law to the effect that torture and cruel, inhuman or degrading punishment or treatment are strictly prohibited by international human rights law. The absolute prohibition of torture, both physical and mental, belongs today to the domain of international jus cogens.52 This prohibition subsists even under the most difficult circumstances such as war, threat of war, the fight against terrorism and any other crimes, state of siege or emergency, civil unrest or domestic conflict, suspension of constitutional guarantees, domestic political instability, or other public emergencies or disasters.53 71. Universal54 and regional55 treaties establish this prohibition, together with the nonrepealable right of all human beings not to be subject to any form of torture. Several international instruments also embody this right and reiterate this prohibition,56 even those relating to international humanitarian law.57 “[a]ll persons deprived of their liberty shall be treated with humanity and with respect for the inherent dignity of the human person.” The sixth and first principles of the Body of Principles for the Protection of All Persons under any form of Detention or Imprisonment, respectively, state the same. For its part, Article 3 of the European Convention for the Protection of Human Rights and Fundamental Freedoms provides that “[n]o one shall be subjected to torture or to inhuman or degrading treatment or punishment.” Cf. International Covenant on Civil and Political Rights, Arts. 7 and 10(1); Body of Principles for the Protection of all Persons under Any Form of Detention or Imprisonment, principles 1 and 6, and European Convention for the Protection of Human Rights and Fundamental Freedoms, Art. 3. 51 Cf.
