Group of Governmental Experts

A Group of Governmental Experts (GGE) is a limited-membership body established by a UN General Assembly resolution, typically on the recommendation of the First Committee, to examine a defined question in the field of disarmament and international security. Members are nominated by their governments but formally serve in their personal expert capacity, though in practice they reflect national positions. Groups generally consist of 15 to 25 experts selected on the basis of equitable geographical distribution, with the five permanent members of the Security Council almost always included.

GGEs operate by consensus, which means a single dissenting expert can block adoption of a final report. They usually meet over the course of one to two years in several sessions in Geneva or New York, supported by the UN Office for Disarmament Affairs (UNODA). The output is a consensus report transmitted to the Secretary-General and the General Assembly, which often serves as the substantive basis for further negotiations or norm-setting.

Notable GGEs include those on information and telecommunications in the context of international security (cyber GGEs), which produced influential consensus reports in 2010, 2013, and 2015 affirming that international law applies to cyberspace, but failed to reach consensus in 2017. Others have addressed lethal autonomous weapons systems (LAWS) under the Convention on Certain Conventional Weapons, the UN Register of Conventional Arms, missiles, verification, and the prevention of an arms race in outer space (PAROS).

GGEs are valued for producing technically grounded, politically negotiated guidance, but criticized for their restricted membership and the ease with which consensus can be blocked. In the cyber domain, dissatisfaction with the GGE format led the General Assembly in 2018 to also establish the parallel, open-ended Open-Ended Working Group (OEWG), in which all UN member states may participate.
