An Oslo appeals court has ruled that mass murderer Anders Breivik has not been treated “inhumanely” by being kept largely in isolation.
It overturned a lower court verdict, which had found Norwegian authorities were violating his human rights.
Breivik, a right-wing extremist is kept in solitary confinement for 22 to 23 hours per day.
His lawyer, Oystein Storrvik, said he would appeal the ruling in the country’s highest court.
“This is the outcome we were expecting, and we have decided to appeal. First, we will try the Supreme Court and if that does not work, we will try the European Court of Human Rights. We will follow our plan. Our strategy was to achieve a change, so that our plan.”
He is currently serving Norway’s longest sentence. Set at 21 years, it can be extended indefinitely if he is still considered dangerous at the end of his term.
The 38-year-old killed 77 people in July 2011 when, disguised as a police officer he set off a bomb in the capital and opened fire at a nearby youth camp on the island of Utoya shortly afterwards.
Breivik has never expressed remorse for his actions, which have gone down as the bloodiest crimes in the country since the Second World War.
