OSLO: Norwegian mass murderer Anders Behring Breivik on Wednesday won his lawsuit against the state over his “inhuman” solitary confinement in prison. “The court… has concluded that the prison conditions constitute inhuman treatment,” the Oslo district court said in its ruling. It said the rightwing extremist’s almost five-year isolation in prison violated Article 3 of the European Convention on Human Rights. Judge Helen Andenaes Sekulic ruled however that Breivik’s right to correspondence, guaranteed by Article 8 of the convention, had not been violated. Norway’s most notorious inmate has been detained in a high-security prison unit since he massacred 77 people in a bomb-and-gun rampage in 2011, the worst peacetime atrocity in the country.
