Dovgy, who led a series of high-profile probes, was dismissed on April 21 allegedly for divulging confidential information and negligently carrying out his duties. Dovgy later appealed to the Basmanny Court of Moscow with a request to be reinstated.
Dovgy said the preliminary hearing at the Basmanny Court was scheduled for June 3, but the investigation committee at the Russian Prosecutor General's Office is refusing to provide documentation with the reasons for his dismissal saying the material is classified as 'top secret.'
Yury Bagrayev, a lawyer for Dovgy, said that "these secret documents have nothing to do with the main issue of restoring [Dovgy] in the post."
Dovgy led inquiries against Deputy Finance Minister Sergei Storchak and General Alexander Bulbov, a former senior drug control official, both in custody accused of embezzling $43 million in state funds, and divulging state secrets and illegal phone tapping respectively.
It has also been alleged that Dovgy accepted 2 million euros ($3 million) in exchange for releasing former Trust Bank chairman Oleg Kolyda from custody in an embezzlement case involving Yukos subsidiary Tomskneft.
A colleague has also allegedly accused him of taking a $1.5 million bribe from a suspect in a criminal case involving the head of the Moscow Petro-Union company.
According to Russian media reports in April, Dovgy, prior to his dismissal from the post, appealed to the Prosecutor General's Office saying his life was in danger.
He wrote in the letter that he trusted neither his boss, Investigative Committee head Alexander Bastrykin, nor his colleagues, adding that he was being followed and that his home in Moscow was being watched.
