Interdisciplinary Group of Independent Experts
{{Orphan|date=August 2024}}
The Interdisciplinary Group of Independent Experts (Grupo Interdisciplinario de Expertos Independientes, GIEI) is the title shared by a series of committees of human rights experts appointed by the Inter-American Commission of Human Rights to investigate particular incidents or scenarios of human rights violations. Legal scholars described the first such group, focused on a mass "disappearance" in Mexico, as "the first experience of international monitoring carried out within a criminal investigation process of its kind. It can be replicated and contribute to the investigation of emblematic cases and regional settings where processes of mass victimisation have occurred."{{Cite journal|last1=Patrón|first1=Mario|last2=Espinosa|first2=Santiago Aguirre|last3=Brewer|first3=Stephanie|last4=de Robina|first4=Sofía|last5=Aguilar|first5=María Luisa|year=2017|title=An Unprecedented Exercise of International Supervision|journal=Sur International Journal on Human Rights|volume=14|issue=25|pages=189–206|issn=1806-6445}}
