JALLOH v. GERMANY JUDGMENT 27 respect of evidence obtained in violation of Article 3 of the Convention, even if the admission of such evidence was not decisive in securing the conviction (see İçöz v. Turkey (dec.), no. 54919/00, 9 January 2003, and Koç v. Turkey (dec.), no. 32580/96, 23 September 2003). The Court reiterates in this connection that Article 3 enshrines one of the most fundamental values of democratic societies. Even in the most difficult circumstances, such as the fight against terrorism and organised crime, the Convention prohibits in absolute terms torture and inhuman or degrading treatment or punishment, irrespective of the victim’s conduct. Unlike most of the substantive clauses of the Convention, Article 3 makes no provision for exceptions and no derogation from it is permissible under Article 15 § 2 even in the event of a public emergency threatening the life of the nation (see, inter alia, Chahal v. the United Kingdom, 15 November 1996, § 79, Reports 1996-V, and Selmouni v. France [GC], no. 25803/94, § 95, ECHR 1999-V). 100. As regards the use of evidence obtained in breach of the right to silence and the privilege against self-incrimination, the Court observes that these are generally recognised international standards which lie at the heart of the notion of a fair procedure under Article 6. Their rationale lies, inter alia, in the protection of the accused against improper compulsion by the authorities, thereby contributing to the avoidance of miscarriages of justice and to the fulfilment of the aims of Article 6. The right not to incriminate oneself, in particular, presupposes that the prosecution in a criminal case seek to prove their case against the accused without resort to evidence obtained through methods of coercion or oppression in defiance of the will of the accused (see, inter alia, Saunders, cited above, § 68; Heaney and McGuinness, cited above, § 40; J.B. v. Switzerland, no. 31827/96, § 64, ECHR 2001-III; and Allan, cited above, § 44). 101. In examining whether a procedure has extinguished the very essence of the privilege against self-incrimination, the Court will have regard, in particular, to the following elements: the nature and degree of the compulsion, the existence of any relevant safeguards in the procedures and the use to which any material so obtained is put (see, for example, Tirado Ortiz and Lozano Martin v. Spain (dec.), no. 43486/98, ECHR 1999-V; Heaney and McGuinness, cited above, §§ 51-55; and Allan, cited above, § 44). 102. The Court has consistently held, however, that the right not to incriminate oneself is primarily concerned with respecting the will of an accused person to remain silent. As commonly understood in the legal systems of the Contracting Parties to the Convention and elsewhere, it does not extend to the use in criminal proceedings of material which may be obtained from the accused through the use of compulsory powers but which has an existence independent of the will of the suspect such as, inter alia, documents acquired pursuant to a warrant, breath, blood, urine, hair or voice
