Born in 1986, Mykola Dadeu is an Ukrainian citizen who resided with his wife in the city of Novorossiysk, Krasnodar Oblast, Russian Federation at the time of his arrest in June 2017. He is a former volunteer who supported the Ukrainian armed forces and volunteer battalions in 2014-2015. The FSB accuses him of “promoting participation in the activities of an extremist organisation [Right Sector] by providing the means to commit the offence.” The accusation is based on his Facebook posts from October 2015 asking for material assistance during the civil blockade of Crimea. As a result of this, according to the Russian investigation unidentified Ukrainian citizens passed on four car tires and two portable transmitters to an unidentified member of the Ukrainian nationalist organisation “Right Sector,” which had been banned by the Russian Supreme Court in 2014. On 21 May 2018, Mykola Dadeu was sentenced to 1 year and 6 months of imprisonment in a colony settlement. In January 2019 he was released from the Russian colony and moved to the territory of Ukraine.

Exculpatory evidence

The fact that Mykola Dadeu is being tried by a Russian court is highly critiqueable as he is an Ukrainian citizen being sued for actions that occurred on the territory of Ukraine. Moreover, the Russian investigation did not provide any evidence that his activities represented a threat to Russia’s national security or interests or that it endangered Russian citizens. Dadeu haв not recognised his guilt and considerув his case to be politically motivated.

Added to these issues concerning the jurisdiction of the Russian authorities are the charges themselves. Indeed, Dadeu is not being accused of “membership” in the “Right Sector” organisation, but only with “promoting participation” in it. However, the identities of individuals who allegedly participated in the activities of  “Right Sector” as a result of Dadeu’s Facebook posts remain unknown. The testimonies added to the case materials do not provide any evidence on Dadeu’s contribution to the Ukrainian nationalist organisation but mostly support the Russian propaganda regarding the presence of “radicals” and “fascists” during the Euromaidan Revolution in Ukraine in 2013-2014. 

Indeed, some consider Dadeu’s case to be a signal to all Ukrainians who supported the Ukrainian armed forces and volunteer battalions, even to those who simply did so by posting online content. This goes in hand with the criminalisation of  “Right Sector” in Russia which can be directly linked to the ongoing conflict opposing Russia and Ukraine. The lack of substantial evidence to support the ban imposed by the Russian Supreme Court on the activities of “Right Sector” illustrates such a trend. The decision mentions for instance an alleged appeal made by Dmitry Yarosh (former leader of “Right Sector”) to Doku Umarov (Chechen islamist rebel chief), which was denied by “Right Sector.” 


Mykola has claimed that he was tortured by the Russian policemen after his detention to extract the needed testimonies. He was severely beaten during several days, insulted, intimidated, and left without any medical assistance.
