Miriam Palma Defensor-Santiago (née Defensor; June 15, 1945 – September 29, 2016) was a Filipino scholar, academic, lawyer, judge, author, and stateswoman who served in all three branches of the Philippine government: judicial, executive, and legislative. Defensor Santiago was named one of The 100 Most Powerful Women in the World in 1997 by The Australian. She was known for being a long-serving Senator of the Republic of the Philippines, an elected judge of the International Criminal Court, and the sole female recipient of the Philippines' highest national honor, the Quezon Service Cross.
In 1988, Defensor Santiago was named laureate of the Ramon Magsaysay Award for government service, with a citation for bold and moral leadership in cleaning up a graft-ridden government agency. After being appointed by President Corazon Aquino as Secretary of Agrarian Reform from 1989 to 1990, she ran in the 1992 presidential election but was controversially defeated in events that involved a car crash injury and power outages during voting process. Defensor Santiago would then serve three terms in the Philippine Senate, where she was known for supporting progressive laws, and authored or campaigned anti-corruption bills.
In 2012, Defensor Santiago became the first Filipina and the first Asian from a developing country to be elected a judge of the International Criminal Court. She later resigned the post, citing chronic fatigue syndrome, which turned out to be lung cancer.
On October 13, 2015, Defensor Santiago controversially declared her third candidacy for President of the Philippines in the 2016 election after her doctors from the United States declared her cancer "stable" and "receded", but lost the election due to public concern for her health. In April 2016, her last appointed post was part of the International Development Law Organization Advisory Council (IDLO), an intergovernmental body that promotes the rule of law. She died from complications from her cancer on September 29, 2016, and was buried days later at Loyola Memorial Park in Marikina.
