“He is focusing on the trial. He is not on a hunger strike at the moment,” Breivik's lawyer Øystein Storrvik told AFP.
The Oslo District Court said on Friday that Breivik's case would be heard between March 15 and 18. It was not immediately known whether Breivik will appear before the court.
Breivik, who killed 77 people in a bombing and shooting rampage in July 2011, wants to take the Norwegian state to court in March over his prison conditions, which he likens to “torture”.
“We believe that his rights are being violated. He is isolated from the other inmates, from other people, and only has contact with health care workers and guards,” Breivik's lawyer Oystein Storrvik told AFP.
On July 22, 2011, Breivik killed eight people in a bomb attack outside a government building in the capital Oslo and later murdered another 69 people, most of them teenagers, when he opened fire at a Labour Youth camp on the island of Utøya.
He was handed a 21-year prison sentence, which can be extended if he is still considered a danger to society.
