The Communist Party attached great importance to the elections for the Constituent Assembly, because it was supposed to decide on the form of the state and its internal organization by enacting the Constitution. Since the KPJ stood for the Soviet Republic of Yugoslavia, it developed a very lively pre-election activity, explaining its views on the organization of the state and highlighting its demands for the improvement of the social position of the working class and the poor peasantry. Fearing a good result of the communists, such as they achieved in the municipal elections, the government of the Kingdom of the Serbs, Croats and Slovenes in every way hindered the election preparations of the communists and their candidacy for deputies, so many were arrested. Filipović himself was arrested just before the elections.
