Ronald Gamarra was a human rights lawyer practicing in Lima when he was one of 22 attorneys asked to serve as a special prosecutor to investigate judicial corruption during the Fujimori-Montesinos regime from 2001 to 2004. During the course of his investigation, Gamarra said he found "declarations by Montesinos in which he admitted that he had intervened in some cases, among them, Yanacocha."
In 2002, Gamarra sent a request to the Peruvian attorney general. He wanted to continue his investigation into possible judicial corruption in the Yanacocha case. Outlining "reasonable presumption" of corruption on the part of judges, he also detailed information received by the prosecutor's office from an "anonymous source" about bank accounts held by judges, which "if authentic … would have constituted the quid pro quo for the decisions pronounced by the judges in favor of Newmont and Buenaventura." He also presented the newly discovered audiotape of the 1998 meeting [video] between Montesinos and Newmont Mining's Larry Kurlander.
The Attorney General took over the case, stating Gamarra did not have jurisdiction, and in 2003, issued a ruling that the bank records contained "no probative evidence whatsoever" to lend credence to allegations that judges "might have solicited or accepted gifts, promises or any other benefit for the purpose of influencing their decisions in the legal case in question."
Asked by FRONTLINE/World why he was taken off the case and the investigation wasn't completed to his satisfaction, Gamarra said, "I am convinced there are strange things that were probably criminal in nature. That neither the French nor the Americans behaved appropriately. And that it did not benefit anyone to investigate … either of those involved in the proceedings, whether it be the French or the Americans."
Gamarra is an attorney at the Instituto de Defensa Legal, a nongovernmental organization based in Lima.
