Serious questions remain on the positions of the various Romanian Communist leaders on the Pătrășcanu case. The matter has not been satisfactorily resolved in the Romanian archives, for the simple reason that all records and transcripts of Politburo and Secretariat discussions on Pătrășcanu were summarily destroyed on Gheorghiu-Dej's orders. In any case, no piece of evidence or confession was obtained by the inquiry until after May 1952, after the purge of Ana Pauker and Teohari Georgescu, who were accused by the Soviet adviser Sakharovskii of having "sabotaged and postponed investigations" in the Pătrășcanu case. The Central Committee plenum that purged them assigned the Pătrășcanu investigation to a team of Securitate officials and their Soviet advisors, directly supervised by Alexandru Drăghici, Alexandru Nicolschi, and Vladimir Mazuru. Under this new team, torture and beating began to be employed in interrogations in the Pătrășcanu case for the first time in the fall of 1952. In time, authorities also alleged that, before 1944, Pătrășcanu, like Zilber, had acted as an agent of Siguranța Statului.
