On November 19, 1942, a military tribunal in the city condemned him to hard labour for life, having found that "He was part of the central leadership of the Communist Party of Romania, being tasked with the indoctrination of the capital's young people.

[4] Among the informal charges brought against Foriș was his alleged attempt to seduce Crăciun during the war years, when she considered herself engaged to Vincze, and of having thus caused her a nervous breakdown which, it was argued, had facilitated her capture by the authorities.

[9][12] Alongside Gheorghe Apostol, Constantin Pîrvulescu, Moghioroș and Borilă, Vincze was Gheorghiu-Dej's emissary during renewed discussions with Pauker, when they attempted to make her admit that she was guilty of "deviationism".
