The role of "amicus curiae" briefs in the World Trade Organization (WTO) dispute settlement system is controversial. The controversy arises due to the governmental nature of WTO disputes. As only WTO members have access to the system, any non-members such as non-governmental organizations (NGOs) are excluded and have no right to be heard. Thus the only way for them to contribute to a WTO decision is through "amicus curiae" briefs.
