On July 6, 1945, Groza and Voitec attended the Inter-Ministerial Conference, regulating contentious issues between Romania and Hungary. It was here that Groza ruled in favor of establishing Bolyai University as a segregated institutions for Hungarians in Romania. In September, Voitec joined the Romanian delegation to Moscow, discussing the application of the Romanian armistice. He and his colleagues were personally received by Soviet leader Joseph Stalin. According to sociologist Dinko Tomašić, this was already a public display of his "obeisance to the lords of the Kremlin." Together with Rădăceanu, Voitec led the wing of the PSDR that called for a greater alignment with PCR policies. Historian George L. Ostafi noted in 1971 that both men, alongside Pas and Barbu Solomon, illustrated the "Marxist-Leninist" current of social democracy, opposing Șerban Voinea's gradualist socialism. A separate right-wing socialist group also survived, with Ioan Flueraș at its helm. It managed to attract into its ranks Ștefanovici, who, by mid 1945, was an organizer of the anti-communist underground. Voitec and Rădăceanu's positioning was noted by Titel Petrescu, who had also emerged as an opponent of the Groza cabinet; he insisted that both men hand in their resignation from government or quit the party, but the PSDR Executive Committee defeated his resolution.
