June 9 (UPI) -- Norway's top court won't hear an appeal by mass murderer Anders Breivik on his isolation confinement in prison.
"None of the elements in the Breivik appeal have any perspective of winning before the Supreme Court," the justices said in a statement Thursday. In Oslo, the the court said Breivik was extremely dangerous and had "very high risk" of committing more serious crimes.
Breivik, who is serving a 21-year sentence for murdering 77 people in a gun and bomb terror attack in 2011, has criticized his treatment in the prison in Skien, which is 80 miles from Oslo
Breivik, 38, said his solitary confinement deeply damaged him and made him even more radical in his neo-Nazi beliefs.
He also said frequent strip searches and being handcuffed during the early part of his incarceration were "inhumane." He claimed microwave meals were "worse than water boarding" and he had to eat with plastic cutlery.
Breivik contends his his treatment was a violation of Article 3 of the European Convention of Human Rights, which prohibits torture and "inhuman or degrading treatment or punishment."
But the court said he was given a three-cell living space that includes an exercise room with equipment, a DVD player, games console, typewriter, as well as books and newspapers.
Oystein Storrvik, Breivik's lawyer, told the Norwegian news agency NTB his client would take his case to the European Court of Human Rights in Strasburg, Germany.
The Oslo District Court originally found that the prison conditions violated his rights, but the state won on appeal.
In July 2011, Breivik killed eight people in a bombing outside a government building in Oslo. Then, he gunned down 69 people, most of them teenagers, at a Labor Party youth camp on the island of Utoya.
