The post-Tito system of collective leadership succeeded in spreading power, though it was widely argued these reforms weakened the federal party organs at the expense of those of the LCY's branches.

The 3rd LCY Congress, which was held from 14 to 22 May 1926, changed the body's name to the Political Bureau of the Central Committee of the Communist Party of Yugoslavia, which was abbreviated to Politburo.

"[7] The party secretaries Tito, Ranković, Edvard Kardelj and Milovan Djilas, who comprised the secretariat, had considerable informal influence on the politburo.

[14] It was argued designating the LCY as the leading force in society was wrong and accordingly, the 6th Congress stated instead the party "mobilises and moves the broadest masses of the people to action by political and organisational means, so that its struggle and achievements make it a leader".

[17] To reduce the over-centralisation of power in key individuals, the same session established the 40-member Commission for the Reorganisation and Further Development of the LCY (CRFD–LCY), which was headed by Mijalko Todorović, to recommend party organisational reform.

[20] Following the decentralisation of socio-economic life that began with the Tito–Stalin split, the commission proposed to institute a fixed system of representation in the presidency and the executive committee.

[22] According to Todorović, many commission members feared the reorganisation was insufficient to halt the centralisation of power and that the presidency would do the same as the former executive committee.

[23] The reorganisation of the former executive committee and the decentralisation of the appointment of mid-level cadres from the centre to the republican leaderships considerably weakened the new presidency's influence.

[24] At the LCY Central Committee's 7th Session on 1 July 1968, it accepted the commission's proposal to expand the presidency to about fifty members and establish a smaller, non-political secretariat attached to it at the 9th Congress.

This proposal was made because the presidency and the executive committee proved too large, and because of this, informal coordination groups were established to enforce policies.

[28] The 7th Session approved these changes, and by the 9th Congress on 11–15 March 1969, Tito, in his function as LCY president, was the only remnant of an independent party centre.

Tito informed the congress "we arrived at the mutual view that it is necessary that we strengthen the centre of the leadership of the League of Communists, and particularly the Executive Bureau".

[40] The new statute also further clarified the right of the branches of republican, autonomous provinces and the LCY organisation in the Yugoslav People's Army (YPA) to elect and dismiss members of the presidency.

[42] The chairmanship was limited to a one-year term and the office rotated in an eight-year cycle among the leadership of the republics, the autonomous provinces and the LCY organisation in the YPA.

[42] Tito rationalised these reforms on 23 October 1979 at a session of the presidency of the 11th LCY Congress:"There are some people—I also have those abroad in mind—who believe that the introduction of the post of chairman with a one-year term calls the continuity and stability of development into question.

it is not individuals who ensure the continuity and stability of development but rather the policy line determined by the party and its leaders and the appropriate behaviour of the leading cadres.

Following the 1989 fall of communism in most of Eastern Europe and in the context of heightened conflict within the LCY on ethnic lines, the Slovene delegation left the congress on 22 January.

It had to promptly communicate the efforts undertaken to the LCY Central Committee, seeking approval for its action at the subsequent session.

The presidency was responsible for making political decisions to ensure the implementation of the policies adopted by Congress and the LCY Central Committee.

Additionally, it was responsible for assessing the political and ideological situation and putting into practice policies, standpoints, and decisions adopted by the party.

The presidency's other responsibilities included collaborating with central and regional committees and the LCY organisation's political-executive organs to exchange ideas and information on current ideological-political issues and plan attitudes and policies.

It was also responsible for overseeing party activities in the YPA and taking measures it saw fit; these actions had to be reported to the LCY Central Committee.

[67] The republics and autonomous provinces, which had a prescribed number of representatives in the LCY Presidency, negotiated with each other to formulate and set federal policies.

The document stipulates the presidency "is a collective, democratic, and political body in which all members have equal rights and responsibilities for its entire work in all areas of its activities".

Members from republics and autonomous provinces who did not participate in the ordinary session of the presidency had the right to be informed as soon as possible about the issues discussed, and their opinions needed to be expressed for the adopted decisions to go into force.

At the 2nd Conference, which was held from 25 to 27 January 1972, the office of Secretary of the Executive Bureau of the Presidency of the LCY Central Committee was established with Stane Dolanc as its first incumbent.

In a manner similar to the LCY president, the chairman had the right to maintain communications with Yugoslav mass organisations, individuals in government and the Assembly of Yugoslavia.

[79] Before the establishment of the chairmanship on 19 October 1978, the secretary was, under the terms of his functions, responsible for organising the supervision and implementation of the ideologies, decisions, and resolutions adopted by the presidency.

[86] Beginning with the reforms of the 5th Session of the Central Committee of the 8th Congress on 4 October 1966, some members favoured a reduction of the LCY's direct interference in government affairs.

[88] At the 11th LCY Congress in 1978, only five individuals concurrently served in the state and party presidencies; these were Tito, Vladimir Bakarić, Petar Stambolić, Fadilj Hodža and Stevan Doronjski.
