In April 1944, acting on the orders of the still imprisoned Gheorghe Gheorghiu-Dej, Pîrvulescu, along with Iosif Rangheț and Emil Bodnăraș, captured and deposed PCR general secretary Ștefan Foriș at gunpoint forcing him to resign his position due to charges by Gheorghiu-Dej that he was a police informer.

Pîrvulescu, Rangheț, and Bodnăraș, as a troika, replaced him as a provisional secretariat until Gheorghiu-Dej escaped from prison and took up the position of general secretary of the party in September 1944.

He also accused the congress of neglecting the country's real problems, and being preoccupied with glorifying Ceaușescu.

Pîrvulescu was kicked out of the room, stripped of his position as delegate to the congress and placed under strict supervision and house arrest.

The document, which was immediately broadcast on Radio Free Europe and Voice of America, was a left-wing critique of Ceaușescu's policies, and led to the swift arrest and interrogation of the signatories by the Securitate, and then to their assignment to forced residence at various locations.
