2002–17 November 2004

Autobiography litigation and limits of freedom of expression in prison

Civil / administrative proceedings

Nilsen sought to retrieve and revise an autobiographical manuscript of several hundred pages describing, among other things, his crimes. Prison authorities prevented him from doing so, and the courts dismissed his Article 10 challenge, finding the restriction proportionate in light of victims' rights and prison order.
