The Norwegian Supreme Court will not take up the appeal lodged by Norwegian mass murderer Anders Behring Breivik protesting his prison conditions, the court said on Thursday.

Breivik was seeking to overturn a March decision by a Norwegian appeals court that ruled his near-isolation in a three-room cell respected human rights.

“The Supreme Court's appeal commission has unanimously decided on June 8, 2017 to not further consider Anders Behring Breivik's appeal in the case Breivik has brought against the state,” the court said in an emailed statement.

“No part of Breivik's appeal has the possibility of winning in front of the Supreme Court,” it added.

“Neither does the case raise questions about the interpretation of the European Convention on Human Rights that have not already been clarified extensively by the European Court of Human Rights.”

Breivik's lawyer was not immediately available for comment, his office said.

It was not immediately clear whether Breivik would appeal to the European Court of Human Rights in Strasbourg, but his lawyer has said in the past that it was an option.
