After months in police custody, Dmitriev's trial began on 1 June 2017. As with other trials in Russia concerning sexual offences against minors, neither press nor public were admitted to the hearings at the Petrozavodsk City Court. On 11 July, four expert witnesses testified on behalf of the defence, casting serious doubts on the interpretation of the evidence by the prosecution and its experts. Dmitriev's attorney Victor Anufriev announced that the hearings had ended for the time being and would resume on 1 August. He expressed the hope that his client could address the court on 22 August and that a verdict would be delivered by 1 September 2017. Thanks to the persistence of the defence, however, the trial continued. On 15 September 2017, the court agreed to submit the photographic evidence to other experts, after the defence had petitioned four times for such a decision.
New assessment of photographs The alternative organisations proposed for this task, first by the prosecution and then by the judge, proved to be obscure private firms without the legal right to act as forensic experts. The hearing scheduled for 18 October was postponed because the new experts were not ready to present their fresh assessment of the same 9 pornographic photographs. A hearing was held on 25 October but the assessment of the photographs was still not ready. On 26 December 2017, the new court-appointed body finally presented the findings of its experts that there was no element of pornography in the photographs taken by Dmitriev and concluded that their purpose was to monitor the health of a sickly child.
Second psychiatric assessment That same day the Petrozavodsk City Court ruled that Yury Dmitriev should undergo a second psychiatric assessment at the
Serbsky Center in Moscow, and that a third assessment of the nine photographs be made by the same body. This decision caused some concern. Dmitriev had already been subject to psychiatric assessment in Petrozavodsk and there had been signs of a revival at the Serbsky Center of its well-documented Soviet-era use as an
instrument of political punishment. On 27 December 2017, the court changed the measure of restraint imposed on Dmitriev. After more than a year in custody at the city's Detention Centre No 1, he would be released on 28 January 2018 (his 62nd birthday), on condition that he did not leave the country. On 28 December, without notifying his defence attorney, the court had Dmitriev flown under escort to Moscow where he was taken to the Serbsky Center to begin assessment. On 30 December, Dmitriev's son delivered food for his father to the Serbsky Center.
Release and resumption of trial On 27 January, Dmitriev was released from custody and allowed to return to his home, on condition that he did not leave the city of Petrozavodsk. On 20 March, the city prosecutor Askerova reaffirmed the accusations against him and demanded 9 years of prison in a severe regime colony. The next court hearing is scheduled for 22 March 2018.
Acquittal and appeal On 5 April 2018, Dmitriev was acquitted of the child pornography charges by Judge Marina Nosova at the conclusion of his trial at the Petrozavodsk City Court. She found him guilty of possessing parts of a shotgun and sentenced him to three months probation plus community service. Dmitriev had denied all the charges.
Novaya Gazeta newspaper commented: "The decision was unprecedented for Russian justice where the percentage of acquittals does not exceed the statistical margin of error." In trials without a jury, the percentage of acquittals in the Russian judicial system is now markedly less than 1% of the total. The result in the Dmitriev Case, therefore, was an achievement against the odds. (In trials where the case is heard before a jury, the proportion of acquittals was higher, around 20% of the total in 2009.) On 13 April 2018, the Petrozavodsk city prosecutor, Yelena Askerova, submitted a formal appeal to the court against the acquittal of Yury Dmitriev on all but one charge. This appeal was accepted by the Supreme Court of Karelia and a hearing was set for Thursday, 14 June. Dmitriev's defence attorney, Victor Anufriev, submitted an appeal against his client's conviction for possessing parts of a firearm. On 14 June 2018, the acquittal was overturned by the Supreme Court of Karelia.
Reaction to trial Journalist Maria Eismont wrote that the trial of Yury Dmitriev in Petrozavodsk was "the most important thing happening in Russia right now". The dramatist and poet
Alexander Gelman commented: "This trial has helped us recognise a remarkable man. It is a barbaric way of discovering good people, but in Russian society it has proved very effective. In this sense, the trial has done something worthwhile." By early December 2017, over seventy video clips of famous Russians speaking in Dmitriev's defence—writers, musicians, priests, historians, film-makers, actors—had been posted on a variety of social media and reposted to his supporters'
Facebook page and to the Dmitriev Affair website. Among them were TV presenter and literary critic Alexander Arkhangelsky, Natalya Solzhenitsyn, film director
Andrey Zvyagintsev, and the sculptor-designer of the
Wall of Sorrow monument,
Georgy Frangulyan, who commented: "What has happened [to Dmitriev] is appalling, it's tragic". ==Second Trial (2018-2020)==
