Oslo: Anders Behring Breivik`s lawyers say the far-right gunman has stuck to his decision not to appeal a terror conviction and prison sentence for bomb and shooting attacks that killed 77 people.
That means the legal process for Norway`s worst peacetime massacre is formally over.
At his sentencing two weeks ago, Breivik said he wouldn`t challenge the ruling and his lawyer Geir Lippestad told reporters he had not changed his mind today, the deadline for an appeal.
The 33-year-old Norwegian now starts serving his 21-year prison term, which can be extended for as long as the self-described "militant nationalist" is considered a danger to society.
Breivik shocked Norway on July 22, 2011, when he set off a bomb in Oslo and then opened fire at the Labor Party`s youth camp.
