y other grounds and must therefore be declared admissible.

(a) General principles
89. The Court reiterates at the outset that in order to fall within the scope of Article 3 ill-treatment must attain a minimum level of severity. The assessment of this minimum is, in the nature of things, relative; it depends on all the circumstances of the case, such as the nature and context of the treatment or punishment, the manner and method of its execution, its duration, its physical or mental effects and, in some instances, the sex, age and state of health of the victim (see T. v. the United Kingdom [GC], No. 24724/94, § 68, 16 December 1999). Allegations of ill-treatment must be supported by appropriate evidence. To assess this evidence, the Court adopts the standard of proof "beyond reasonable doubt" but adds that such proof may follow from the coexistence of sufficiently strong, clear and concordant inferences or of similar unrebutted presumptions of fact (see Jalloh v. Germany [GC], No. 54810/00, § 67, ECHR 2006-IX).
90. The Court further reiterates that extradition by a Contracting State may give rise to an issue under Article 3, and hence engage the responsibility of that State under the Convention, where substantial grounds have been shown for believing that the person in question would, if extradited, face a real risk of being subjected to treatment contrary to Article 3 of the Convention in the receiving country. The establishment of such responsibility inevitably involves an assessment of conditions in the requesting country against the standards of Article 3 of the Convention. Nonetheless, there is no question of adjudicating on or establishing the responsibility of the receiving country, whether under general international law, under the Convention or otherwise (see Soering v. the United Kingdom, 7 July 1989, § 91, Series A No. 161).
91. In determining whether it has been shown that the applicant runs a real risk, if extradited, of suffering treatment proscribed by Article 3, the Court will assess the issue in the light of all the material placed before it or, if necessary, material obtained proprio motu (see H.L.R. v. France, 29 April 1997, § 37, Reports of Judgments and Decisions 1997-III). Since the nature of the Contracting States' responsibility under Article 3 in cases of this kind lies in the act of exposing an individual to the risk of ill-treatment, the existence of the risk must be assessed primarily with reference to those facts which were known or ought to have been known to the Contracting State at the time of the extradition (see Cruz Varas and Others v. Sweden, 20 March 1991, §§ 75 - 76, Series A No. 201, and Vilvarajah and Others v. the United Kingdom, 30 October 1991, § 107, Series A No. 215). However, if the applicant has not been extradited or deported when the Court examines the case, the relevant time will be that of the proceedings before the Court (see Chahal v. the United Kingdom, 15 November 1996, §§ 85 - 86, Reports 1996-V).
92. In order to determine whether there is a risk of ill-treatment, the Court must examine the foreseeable consequences of sending the applicant to the receiving country, bearing in mind the general situation there and his personal circumstances (see Vilvarajah and Others, cited above, § 108 in fine). It is in principle for the applicant to adduce evidence capable of proving that there are substantial grounds for believing that, if the measure complained of were to be implemented, he would be exposed to a real risk of being subjected to treatment contrary to Article 3 (see N. v. Finland, No. 38885/02, § 167, 26 July 2005). Where such evidence is adduced, it is for the Government to dispel any doubts about it (see Ryabikin v. Russia, No. 8320/04, § 112, 19 June 2008).
93. As regards the general situation in a particular country, the Court considers that it can attach certain
