Ill-treatment must attain a minimum level of severity if it is to fall within the scope of protection of this provision. In this regard, the circumstances of the case, in particular the duration of the treatment, its physical or mental effects, the sex, age and state of health of the persons concerned must be taken into account (cf. ECtHR, Raninen v. Finland, Judgment of 16 December 1997, No. 152/1996/771/972, § 55; ECtHR <GC>, Labita v. Italy, Judgment of 6 April 2000, No. 26772/95, § 120; ECtHR <GC, Kudła v. Poland, Judgment of 26 October 2000, No. 30210/96, § 91; ECtHR <GC>, Jalloh v. Germany, Judgment of 11 July 2006, No. 54810/00, § 67; established case-law). Treatment is degrading where it arouses in the persons concerned feelings of fear, anguish and inferiority, which goes beyond the inevitable element of suffering or humiliation connected with a given form of legitimate treatment or punishment; the question whether the purpose of the treatment was to humiliate or debase the person concerned is a further factor to be taken into account (cf. ECtHR <GC>, Labita v. Italy, Judgment of 6 April 2000, No. 26772/95, § 120; ECtHR <GC>, Kudła v. Poland, Judgment of 26 October 2000, No. 30210/96, § 92; EGMR, Keenan v. The United Kingdom, Judgment of 3 April 2001, No. 27229/95, § 110; ECtHR, Price v. The United Kingdom, Judgment of 10 July 2001, No. 33394/96, § 24; ECtHR, Mouisel v. France, Judgment of 14 November 2002, No. 67263/01, § 37).
