NFJ, the KPJ dominated the group. In preparation of the 1945 elections, the AVNOJ was expanded by addition of pre-war members of parliament deemed not compromised by cooperation with the Axis powers. In effect, this meant addition of liberal and left-leaning politicians who could not be accused of collaborating with the Axis. Civil rights were curbed in the summer of 1945 when new legislation on crimes against the people and the state, curtailing the rights of assembly and freedom of the press. Middle and lower levels of bureaucracy were filled with the ranks of former Partisans. Following a boycott proclamation by the Grol's Democrats, the elections were carried out like a referendum–voting for the NFJ and against it. The NFJ slate received the highest approval in Croatia where the HRSS was aligned with the KPJ (81%), followed by Slovenia (78%) despite non-participation by the pre-war parties in the NFJ slate there, and the lowest support in Serbia (67%). This result is attributed to monarchism and the boycott. Ultimately, 88,43% of the electorate voted, and the NFJ was supported by 88,69% of the votes cast. The suffrage was universal for everyone over the age of 18 (including women for the first time), except those charged with Axis collaboration. Former Partisans could vote even if under 18. The KPJ received 404 representatives of 524 (77%) in the bicameral Constituent Assembly. According to Đilas and Vladimir Velebit, the KPJ expected to win a majority of 60–65% even if the election were to guarantee fair competition. They based the opinion on the belief that the KPJ offered the opportunity to live in peace, an agrarian reform, and on post-war euphoria. In 1946, the parliament adopted a new Constitution implementing the ethnic federalism as the KPJ's solution for the national question, modelled on the Soviet Union. By 1947, the KPJ declared that its programme was the NFJ's programme and that the KPJ is in the forefront of the NFJ. Tito linked the collapse of the pre-war Yugoslavia with the multi-party system of government, justifying suppression of political opposition parties in the post-war context–calling the multi-party system incompatible with the socialist order and unnecessary. In October 1948, the four existing republican communist parties were complemented by two more: the Communist Party of Bosnia and Herzegovina, and the Communist Party of Montenegro.
