Norwegian mass murderer, Anders Behring Breivik, went to court on Tuesday to file suit against the Norwegian government for "violating human rights" by holding him in isolated from other prisoners for more than five years.
Breivik was handed a maximum 21-year sentence for killing eight people in a bomb attack outside a government building in Oslo and then murdering another 69 people in a rampage at a Labour Youth camp on the island of Utoya in 2011.
His shooting spree lasted an hour and 13 minutes, as he methodically stalked and killed many of the up-and-coming leaders of Labour, Norway's dominant political party, which he blamed for the rise of multiculturalism.
Oystein Storrvik, Breivik’s lawyer, said that his client is suffering “clear damage from his isolation,” which they say violates a ban on inhuman and degrading treatment under the European Convention on Human Rights (ECHR).
"One of his main things to do [in prison] was to study and he has stopped that now, and I feel that is a sign that isolation has been negative to his psychological health," Storrvik told reporters before the March 15-18 trial.
"He wants contact with other people."
However, Oslo's office of the Attorney General says there is no case to answer, saying in pre-trial documents: "there is no evidence that the plaintiff has physical or mental problems as a result of prison conditions."
Breivik, 37, also accuses the government of breaching another clause of ECHR that guarantees the right to respect "private and family life" and "correspondence."
In prison, he has a three-room cell with a television and a computer, but no Internet access. He is allowed out into a yard for exercise. He only meets guards and medical personnel - even Storrvik has to speak to him through glass.
The case will be heard in a converted gym at the grey, concrete Skien jail, south of Oslo, where Breivik is being held.
