On the covert orders of the KGB, thousands of social and political reformers—Soviet dissidents—were incarcerated in mental hospitals after being labelled with diagnoses of sluggish schizophrenia. Snezhnevsky himself diagnosed, or was otherwise involved in, a series of famous dissident cases, and in dozens of cases he personally signed a commission decision on the legal insanity of dissidents who were in fact mentally healthy, including Vladimir Bukovsky, Natalya Gorbanevskaya, Leonid Plyushch, Mikola Plakhotnyuk, and Pyotr Grigorenko. Revaz Korinteli, a professor of the Grigol Robakidze University, says that Snezhnevsky broadened the borders of schizophrenia, and in this connection there was legal and theoretical justification for employing compulsory, involuntary treatment of dissenters in mental hospitals.
