Mamani v. Sanchez de Lozada and Sanchez Berzain

In September 2007, with the assistance of the International Human Rights Clinic and others, Bolivian plaintiffs initiated an Alien Tort Statute (ATS) and Torture Victim Protection Act (TVPA) suit against former Bolivian President Gonzalo Sánchez de Lozada and former Minister of Defense José Carlos Sánchez Berzaín.  The case, Mamani et al. v. Sánchez de Lozada and Sánchez Berzaín, alleges that the Defendants planned and carried out attacks on civilians that left dozens dead and hundreds injured in 2003 as part of a government effort to suppress opposition to a controversial economic policy.

The complaint seeks damages against the Defendants for their involvement in the extrajudicial killings and crimes against humanity. Since the case was originally filed, seven former high-ranking Bolivian officials and military leaders have been convicted for their participation in the violence of 2003. Sánchez de Lozada and Sánchez Berzaín, however, have found a safe harbor from justice in the United States for nearly a decade.

The complaint alleges that the Defendants waged a deliberate campaign of killing, calculating months in advance it would take thousands of civilian deaths to stop anticipated protests over their economic policy. Refusing to negotiate with protesters, the Defendants chose to rely on military forces, including special forces units, to target innocent civilians. The complaint also details how, in addition to planning the campaign, the Defendants were intimately involved in its execution, including participating in the operations against the civilian population.

Among the Plaintiffs in the case is Etelvina Ramos Mamani, who watched her eight-year old daughter Marlene die in her arms, after Marlene was targeted by a military sharpshooter while standing at a window in their home. As national outrage and protests intensified over Marlene’s death and the many other deaths and injuries, President Gonzalo Sánchez de Lozada resigned. He and Sánchez Berzaín then fled to the United States, where they currently reside.

As co-counsel, the Clinic has been involved in all phases of the litigation from the outset, including researching and drafting for the complaint and various motions and briefs, assisting with oral arguments, and undertaking more than six investigative missions to Bolivia since 2007.
