Though already declared legally insane, Norway killer Anders Behring Breivik will under go a new court-ordered psychiatric evaluation.

While the Oslo court said on Friday that a new evaluation wouldn't discredit the previous report, Judge Wenche Elizabeth Arntzen still felt that a new evaluation was necessary.

Many in Norway have questioned the original report, saying that it wasn't possible for someone insane to carry out such a sophisticated and well-planned massacre. Additionally, Arntzen noted that the court has not observed any psychotic behavior during Breivik's months in pre-trial detention.

These circumstances point toward letting independent experts conduct a new evaluation of the suspect's accountability, Arntzen said.

Continually defiant, Breivik has rejected the evaluations and may not be cooperative.

“My client has made it clear that he does not want a new psychiatric investigation. He has no confidence that any new experts will understand his motives for carrying out his actions,” Defense counsel Geir Lippestad told Norway's NRK paper.

During the original evaluation, Breivik refused to talk to psychiatrists Synne Sørheim and Torgeir Husby. Still, the two experts found that Breivik lives in his own delusional universe where all his thoughts and acts are guided by his delusions.

While there is substantial evidence to support the claim -- such as his 1,500-page manifesto 2083: A European Declaration of Independence and his continued but unsubstantiated insistence that there is a network of Knights Templar units fighting around Europe -- the ruling goes against statements made by judges and Breivik's own lawyers, who have stated in previous court appearances that Breivik is not insane.

The insanity charge was especially controversial because it could affect the upcoming sentencing. While the prosecution is confident that Breivik will be incarcerated regardless of his psychological state, his defense could try to get the killer sent to psychiatric care instead of prison.

What will happen in the case, no matter what the conclusion, is that he [Breivik] will of course be incarcerated, John Christian Elden, a lawyer for the victims of the Oslo massacre, stated.

And if the outcome is criminally sane or insane, that is, first and foremost a psychiatric question. The most important thing in our clients' opinion is that he will not be able to walk the streets.

Breivik has admitted to the bombing and shooting spree that killed 77 people in and around Oslo on July 22, but has pled not guilty to the charges of murder, acts of terrorism, destabilizing or destroying basic functions of society and creating serious fear in the population.

Breivik has claimed that he is innocent because his actions were done during a state of war, and considers himself a patriot and a soldier in the fight against immigration and Islam in Europe.

The new psychologists have been identified as Terje Tørrison and Agnar Aspaas.
