Nils Melzer

Melzer visited Julian Assange in prison on 9 May 2019, accompanied by two medical experts specialised in examining potential victims of torture and other means of ill-treatment, to assess the conditions in which he was held. On 31 May, Melzer described the treatment Assange had received from the United States, United Kingdom, Sweden, and Ecuador as psychological torture and the U.S. indictments as the "criminalisation of investigative journalism".[7][8]

In November 2019 Melzer criticised the UK government for placing Assange's life at risk by ignoring previous warnings about the state of his health. He said Assange "continues to be detained under oppressive conditions of isolation and surveillance, not justified by his detention status". He also said that Assange's access to legal counsel and documents were being severely obstructed, preventing him from preparing a defence against "the world's most powerful government". Melzer asked the UK government to stop Assange's extradition to the US, release him and allow him to "recover his health and rebuild his personal and professional life".[9]

More than 300 human rights lawyers and law professors criticized Melzer's approach to "allegations of sexual assault" in an open letter. While considering the "overarching argument" may merit attention, they wrote that they were "deeply disturbed by the way he approaches the allegations of sexual assault in this case". On the issue of sexual violence, they wrote that Melzer's intervention was "both legally erroneous and harmful to the development and protection of human rights law."[10] Melzer stood by his statement that the evidence collected in Sweden was not a basis for investigating the suspected rape and expressed hope that it would not divert attention away from the problems in the case of Assange.[11] The three initiators of the open letter welcomed Melzer's clarification.[12]

The Swedish prosecutor announced that the investigation had been dropped as of 19 November 2019.[13]

One of the women interviewed by Melzer later criticised him and demanded his resignation. She said that by defining how a "proper rape-victim" would have to act, Melzer was engaging in victim blaming and that his report was partially "untrue and defamatory".[14]

In a January 2020 interview, Melzer said he had never seen a comparable case where a person was subjected to nine years of a preliminary investigation for rape without charges being filed. He said Assange's lawyers made more than 30 offers to arrange for Assange to visit Sweden in exchange for a guarantee that he would not be extradited to the U.S. and described such diplomatic assurances as routine international practice. Melzer made various criticisms of the Swedish prosecutors, including for changing one of the women's statements without her involvement in order to make it sound like a possible rape. Melzer said that the Swedish rape investigation was an abuse of process aimed at pushing Assange into a position from which he was unable to defend himself.[15] Melzer sent an official letter to Sweden listing fifty indications that there had been serious procedural violations in its treatment of Assange.[16]

Melzer's book, The Trial of Julian Assange: a Story of Persecution was published by Verso Books in February 2022. It recounts his investigation of Assange's case.[17] In the book, Melzer wrote that Assange's treatment "exposes a fundamental systemic failure that severely undermines the integrity of our democratic, rule-of-law institutions.". Matthias von Hein wrote that the book "raises strong doubts about the strength of our justice system in the face of powerful interests that manipulate and abuse it". In relation to the Swedish investigation, von Hein wrote that "Melzer meticulously describes how the Swedish judiciary portrayed Julian Assange as a rapist for years, without giving him the chance to respond".[16]
