[2] Although born in Puntarenas, the first child of Emiliano Odio Madrigal and Esperanza Benito Ibañez, most of her early life was spent in San José, where she attended the Colegio Superior de Señoritas.

[3] From 1976 to 1978 she served as Secretary to the Colegio de Abogados, the bar association of Costa Rica, and in 1978 was appointed to the joint offices of Minister of Justice and Attorney General, which she held until 1982 when the National Liberation Party took the presidency.

Her interpretation, based on a case of two Serbian women raped in the Čelebići detention camp, is now an accepted principle of international law.

In 1998 Odio Benito left ICTY as a consequence of becoming Vice-President, but she continued to play an active role in related areas of the law.

When the International Criminal Court sentenced Congolese warlord Thomas Lubanga to 14 years in prison in July 2012 for using child soldiers in his rebel army in 2002 and 2003 – the first sentence imposed by the court in its history –, Odio Benito disagreed with her two fellow judges and in a dissenting opinion said that 15 years would have been more appropriate given the harm done to the victims and their families,[5] particularly due to harsh punishments and sexual violence against the UPC's child soldiers.
