In the first post-war decade party organs still controlled the whole structure of the government and management. However, the authoritative - bureaucratic system created by I.V.Stalin required constant forcing and keeping in the party-administrative machinery itself conditions of mutual distrust, search of internal opponents. Therefore with a view of "effective" management of the party-state structures Stalin widely used repressive bodies.
In 40s - the beginning of 50s the so-called " Leningrad case ", " mingrelian case", " Jewish antifascist committee case ", " case of doctors - poisoners " and others were provoked by the 'leader'.Actual executors became the confidants of the "leader".
October 1, 1950 the military board of the Supreme court of the USSR under Stalin's authority and approval sentenced to execution N.A.Voznesensky - a member of Political Bureau TSK of the party, the vice-president of the SM of the USSR, chairman of Gosplan of the USSR; A.A.Kuznetsov - member of the Orgbureau, secretary of the TSK VKP (b), the head of defense of Leningrad within war; M.I.Rodionov - member of the Orgbureau of the TSK VKP (b), the chairman of the SM of RSFSR; P.S.Popkov - the candidate in members of the TSK VKP (b), the first secretary of Leningrad regional and municipal committees of the party; Y.F.Kapustin - the second secretary of the Leningrad municipal committee of the party; P.G.Lazutin - the chairman of the Leningrad municipal executive committee.
All convicted were accused of creation of antiparty group, the subversive activities, directed on transformation of the Leningrad party organization into the support for struggle against party and TSK. All heads of the Leningrad regional and municipal committees of the party, regional Communist Party organizations of Leningrad and regions, almost all the Soviet and statesmen, put forward after war from Leningrad to leading positions underwent repressions.
Only in Leningrad in 1949-1952 more than 2 thousand of communists were dismissed. After punishment of " the central group " in 1950, legal procedures took place in various regions of the country, during these processes verdicts featured with cruelty and predeterminacy.
The 'Case" got on a large scale, the cases 'of the Smolninsky region " and 'of the Dzerzhinsky region " etc. appeared. Stalin's death changed the conditions, and already on April 30, 1954 the Supreme court of the USSR rehabilitated a part of convicted on " the Leningrad business ".
Under the same worked through scheme the " mingrelian " case developed, having delivered in 1951 a hard blow to the Georgian party organization. It was based on the version about existence in Georgia of the " mingrelian-nationalist group ", connected with the Parisian center of the Georgian emigration and conducting espionage activity. Many leading party and Soviet officials were dismissed from the posts and arrested; thousands of innocent people underwent repressions.
