The Constitutional Assembly was convened on 12 December. Election results indicated that the electorate was nearly evenly split on the issue of centralisation of the state. The division prompted the DS and the NRS to compromise to achieve a unitary constitution of the state, and not to make any concessions to the proponents of decentralisation. The DS and the NRS formed a Serbian bloc supporting the government and its draft of what would become the
Vidovdan Constitution. Since the bloc did not receive the majority of the parliamentary seats, the DS and the NRS obtained support from three other parties. The first was the JMO, which gave up its opposition to a unitary constitution in exchange for concessions that the administrative unity of Bosnia and Herzegovina within Yugoslavia would be maintained. They also obtained promises for more offices for the JMO in the provincial government, and financial compensation for the land confiscated from Bosnian
Muslim landlords in the
land reform in interwar Yugoslavia. Further votes came from
Džemijet, representing the Muslim population in Southern Serbia. The party gave the Serbian bloc its support on similar terms to those offered to the JMO, promising Muslim landowners money in exchange for estates they stood to lose in the land reform. Finally, a faction of the
Agrarian Party supported the Serbian bloc in exchange for political concessions, including the position of the Yugoslav ambassador to
Czechoslovakia for the faction's leader
Bogumil Vošnjak. The Constitutional Assembly's
rules of order were determined by a government decree. The rules ignored the pre-unification demand by the National Council of Slovenes, Croats and Serbs that a two-thirds majority adopt the constitution. The demand relied on wording of the Corfu Declaration calling for a
qualified majority. The government argued that going beyond the majority of all members present and voting was sufficient to count as a qualified majority in the spirit of the Corfu Declaration. The Croats viewed the decision not to require a two-thirds majority as a betrayal, as they considered the Corfu Declaration a binding agreement on the need to adopt the constitution by more than a simple majority. The election established the HSS as the leading political party in Croatia-Slavonia. It outperformed the
Croatian Union and the
Party of Rights combined by about 45 percentage points. At a rally held on 8 December, Radić announced that the HSS would not participate in the work of the Constitutional Assembly because the party members advocated establishment of a republic instead of the monarchy and held the parliament a sovereign institution. Therefore, they would not swear an oath of allegiance to the king. The Party of Rights followed the HSS and decided not to participate in the parliament. In May 1921, the Croatian Union also walked out of the parliament, protesting against the decision-making by a simple majority. On 21 May, the HSS, the Party of Rights, and the Croatian Union, acting as the newly established
Croatian Bloc coalition, drew up a declaration on behalf of their elected members of the Constitutional Assembly. In the declaration, they denied that the remaining assembly was legitimate or entitled to enact a constitution binding for Croats or Croatia. The KPJ achieved the best 1920 election results in large cities, and in Montenegro and
Macedonia as a result of protest votes against the regime's past or expected actions. These votes came from unemployed urban voters and voters in regions with no other attractive national or regional opposition parties in Slovenia, Croatia-Slavonia, and Bosnia and Herzegovina. KPJ's
Sima Marković was the first to criticise the rules of order as illegal at the floor of the assembly. By the end of 1920, following a series of KPJ-led strikes, the government issued the
Obznana decree, which banned communist propaganda, ordered the seizure of KPJ's newspapers and prohibited the work of organisations affiliated with the party. On 11 June 1921, the KPJ left the Constitutional Assembly. Announcing the party's decision,
Filip Filipović said that the KPJ was leaving because the government had made any criticism by the opposition impossible. Two days later, the SLS also left the parliament after the speaker
Ivan Ribar dismissed their request to postpone discussions on the section of the draft constitution by authority of the central government. ==Notes==
