She served as a judge on the Criminal Court of First Instance in the 7th district of the city of Montevideo, where she was investigating more than 50 complaints of human rights violations linked to the civil-military dictatorship.

In 2010 she condemned former president and dictator Juan María Bordaberry for crimes of attack against the Constitution, forced disappearance of persons, and political murder.

In the same way the Chambers were dissolved, the Parliament was suppressed and with it the legislative function, thus cutting off one of the basic pillars of the democratic system: the most important, the separation of powers.

This crime, which would be prescribed after 20 years, could not be tried previously due to the interruption of normal functioning of the rule of law between 1973 and 1985, and for procedural reasons that hindered the judicial process until 2006.

The search for the plane and its crew by the National Navy did not yield results until 20 July, when they found the remains of the ship with the cooperation of Héctor Bado, a specialist in historical shipwrecks.

After this finding, the judge sent a letter to the Ministry of Defense to resume the search with the participation of Bado, since she considered that the elements found did not allow a complete expert opinion.

Finally, it was ordered to resume the search in December 2013,[10] although the judge did not obtain new information to continue the investigation until the moment of being transferred to another court, being removed from this and other cases.

Several public figures (Mirtha Guianze [es] and Washington Beltrán, among others), as well as social and political organizations, expressed consternation and rejection of the decision to remove the judge from the criminal court at a time when she was investigating several cases of human rights violations, in addition to the disappearance of the Air Class plane.

Baldemar Tarocco, vice president of Crysol (the association of former political prisoners of Uruguay), stressed that this was not the first transfer of judges who worked in cases related to human rights and the recent past.

[2] On 15 February, the day on which the transfer was completed, a public demonstration took place outside the headquarters of the SCJ, and some protesters were prosecuted for the crime of asonada (unrest), among them the social activists Irma Leites and Álvaro Jaume, and the politician Jorge Zabalza.

[17] The name of the judge was proposed by the Broad Front in the General Assembly of the Legislature, where she was finally elected along with Wilder Tyler, Mariana Blengio, María Josefina Plá, and Juan Faroppa [es] on 1 August 2017.
