Bureau and Extended Bureau 

In order to function effectively, the Commission needs to organize and prepare its work carefully and in advance. Such tasks are carried out by the Bureau and the Extended Bureau of the Commission, which play an active role in the preparation of the regular and the inter-sessional meetings with the assistance of the Secretariat.

The Bureau of the Commission is composed of the Chairperson, three Vice-Chairpersons and one Rapporteur. At the end of its reconvened session, the Commission elects its Bureau for the next session. The Extended Bureau also includes the Chairpersons of the five regional groups, the European Union and the Group of 77 and China.

In view of the practice of rotation of offices based on regional distribution, the officers at the fifty-eighth session of the Commission are from the following regional groups: Chairperson from the Asia-Pacific Group; the three Vice-Chairpersons from the Eastern European Group, Western European and Other States (WEOG) and Latin America and the Caribbean Group (GRULAC), and the rapporteur from the African Group.
