As in other Chapters there is neither a written constitution nor rules of procedure inscribed. The Chapter functions smoothly on the basis of consensus arrived at through the methods of work and through convention.

The Group consists of the Bureau, the Plenary and Ad hoc Working Groups. The Bureau consists of the President, Vice-President, Secretary, Treasurer, the President of the four main constituents of the Group, i.e. the Electoral Groups III, IV, Va and Vb, one representative (from each of the above Electoral Groups) elected from among the members of the G77, the immediate Past President of the Group and the Chairman of the NAM. Previously, the Secretary was appointed for a period of three years, but now the term of office has been reduced to two years.

The links between the G77 Chapters are loose and their procedures are not uniform. For example, in Geneva, regional groups of the G77 covering Asia, Africa and Latin America meet separately to discuss and endorse decisions of the G77 as a whole. In New York, there is an Asian Caucus that is not confined to the G77 but includes Japan and China.

The move, however, is to steadily strengthen these links and introduce uniform procedures. For example, a uniform tenure of office of one year for all Chairpersons/Co-ordinators of the G77 has been introduced.

The G77 does not have the benefit of its own secretariat. In New York, with the support of the PGTF (Perreze Guerrero Trust Fund), one or two representatives of G77 governments are delegated to assist the G77 in its work in logistical and organizational areas.

The biennial meetings of Chairpersons/Co-ordinators of the various Chapters of G77 have proved to be exceedingly helpful. Until quite recently it was essentially in UNCTAD that the G77 concentrated much of its work. Since UNCTAD 2 in 1968 full-scale Ministerial Meetings of the entire G77 have been held periodically to prepare for the global conference of UNCTAD. Not only did UNCTAD give adequate accommodation in the Secretariat for the G77 office but it also provided secretarial assistance.

In the late 1980s the Paris Chapter requested facilities from UNESCO. In 1993 the Director-General of UNESCO was kind enough to provide the Group with further separate office space and, since 1994, facilities for photocopying, etc.
