Norwegian mass murderer Anders Breivik had his human rights violated while in prison, a court has ruled.
The Prison conditions Breivik lived in breached an article in the European Convention on Human Rights prohibiting inhuman and degrading treatment.
The court dismissed Breivik's claim that the government had also violated his right to respect for private and family life.
Breivik massacred 77 people in an attack on a summer camp in 2011.
The 37-year-old claimed his prison conditions violate the European Convention on Human Rights.
At court hearings in Skien prison in southern Norway last month, he complained that prison authorities wouldn't let him communicate with or receive visits from other right-wing extremists.
Government lawyers dismissed his complaints, saying Breivik remains a dangerous inmate who could inspire others to commit similar attacks.
Breivik made a Nazi salute during one court appearance in the case, staring at journalists as he made the gesture.
