Diego García-Sayán Larrabure (born August 2, 1950), is a former Justice and Foreign Affairs Minister of Perú, and until recently a sitting judge on the Inter-American Court of Human Rights. after having presided over it in the period from 2010 to 2012. On August 15, 2014, the Peruvian Government formally announced its launching of Dr. Garcia-Sayan's candidacy in the upcoming 2015 election for the post of Secretary-General of the Organization of American States (OAS), a decision which was rescinded unilaterally by the candidate himself on October 1, 2014, as a result of what he said was the said Government's lack of proper support towards that end.
García Sayán was born in Brooklyn, New York, the youngest son of Dr. Enrique García-Sayán, a former Foreign Affairs Minister of Perú who, in 1946, was associated, along with President José Luis Bustamante y Rivero, with launching the so-called "200 Nautical Miles (370.4 km) Territorial Doctrine", currently being adhered to and claimed by Benin, Congo, Ecuador, El Salvador, Liberia, Perú and Somalia. After the 1948 coup d´état which overthrew the constitutionally elected Government of President Bustamante, Dr. García-Sayán went into exile, working with the United Nations first in New York, then in Geneva, which led a year later to his son Diego's birth in the United States.
García Sayán co-founded the Peruvian Center for International Studies (CEPEI) in 1980. On 27 January 2017, United Nations Secretary-General António Guterres designated him a member of the Selection Mechanism for the Special Jurisdiction for Peace, established in Colombia in 2016. He has also served as the Chairperson of the United Nations Working Group on Enforced or Involuntary Disappearances. In the Peruvian government he has served as a member of Congress (2000) and, as noted earlier, has held the portfolios of Minister of Justice, (2000–2001) and Minister of Foreign Affairs (2001–2002).
