In front of mounting Communist influence, Hațieganu approached Iuliu Maniu with a proposal to establish direct contacts with the Western Allies by having Ion Mihalache evade the country (July 1947); the attempt, known as the Tămădău Affair, eventually led to the prosecution of the PNȚ leadership during a show trial and to an official ban on all party activities.[6]
Arrested in Sibiu by the authorities of Communist Romania, he was investigated by the notorious Securitate officer Gheorghe Crăciun [ro].[1] Hațieganu was prosecuted and sentenced on November 6, 1948 to three years in prison for "PNȚ activism" and "sabotage".[7] He was incarcerated at Cluj, Sighet, Jilava, Văcărești, and Ocnele Mari.[8] In 1951, the term of his imprisonment in the infamous Sighet Prison was increased by another 60 months. He was released on June 15, 1955,[7] and died in Cluj four years later.
