The criminal trial of Anders Behring Breivik, known as Norway v. Anders Behring Breivik, took place in the Oslo District Court from 16 April 2012 to 24 August 2012. Breivik was charged with gross terrorism under Section 141 of the Norwegian Penal Code, the premeditated murder of 77 people, and the premeditated attempted murder of 56 others in connection with the 22 July 2011 attacks: a car bomb in Oslo's government quarter that killed 8 and injured over 200, followed by a mass shooting at the Workers' Youth League summer camp on Utøya island, where 69 were killed, mostly teenagers. The attacks were motivated by Breivik's far-right, anti-Islam, and anti-multiculturalist ideology, as detailed in his 1,500-page manifesto. The trial was significant for Norway's judicial system, addressing questions of criminal responsibility, sanity (two psychiatric evaluations initially deemed him insane but were overturned), and the balance between punishment and rehabilitation in a country with a strong welfare-oriented penal system. Breivik rejected the legitimacy of the court, performed a Nazi salute, and used the platform to propagate his views. He was declared sane by the court, convicted on all counts, and sentenced to 21 years' preventive detention—the maximum under Norwegian law at the time, with provisions for extension if he remains a threat to society. The case highlighted Norway's response to domestic terrorism, influenced global discussions on far-right extremism, and led to minor legal reforms, including adjustments to terrorism sentencing. Appeals were denied by the Borgarting Court of Appeal in 2013 and the Supreme Court of Norway in 2014.
