Today’s guest post is from Professor Gregory Michener, Brazilian School of Public and Business Administration, Getulio Vargas Foundation (FGV-EBAPE) and Breno Cerqueira, a Brazilian public official. The post is based on an op-ed originally published (in Portuguese) in the Folha de São Paulo newspaper.

Earlier this month, a single Justice on Brazil’s Supreme Court invalidated, on dubious procedural grounds, the plea bargain that prosecutors had reached seven years ago with the Odebrecht firm, which resolved serious corruption charges that the prosecutors had brought against the firm. The alleged impropriety concerned how the Brazilian prosecutors had interacted with their counterparts in the United States and Switzerland, which had also brought cases against Odebrecht, which ultimately pled guilty and paid penalties in all three jurisdictions. According to Justice Toffoli (who, incidentally, had been implicated in Odebrecht’s wrongdoing when he was Solicitor General, though he succeeded in suppressing reports about his alleged wrongdoing), the Brazilian prosecutors from the Lava Jato (“Car Wash”) Task Force had engaged in discussions of the case with their U.S. and Swiss counterparts without those foreign prosecutors having first filed a formal official request for international legal cooperation, and without including representatives from the Brazilian Ministries of Justice and Foreign Affairs in the discussions. Strikingly, Justice Toffoli ruled that none of the evidence obtained from Odebrecht in the plea deal—and which was used in hundreds of other cases—could lawfully be used. Tofolli’s decision thereby threatens to undo the vast majority of the convictions that the Car Wash prosecutors had secured before the task force was disbanded.

This decision is troubling for a number of reasons. For one thing, the decision put the private interests of defendants ahead of the public interest of deterring and prosecuting corruption. No one denies that due process is important. However, preserving indisputable evidence of corruption can be achieved without a wholesale dismissal of charges. The nullification of the Odebrecht case is a nullification of justice and of the public interest.

Perhaps even more troubling, the decision is unsettlingly aligned with President Lula’s promise of revenge against the Car Wash Operation—and the individual judges, prosecutors, and others involved in that operation. Lula himself was jailed for 18 months after he was convicted for taking a bribe (in the form of a luxury apartment)— a conviction that was ultimately overturned on technical grounds (principally that the case was brought in the wrong venue). Lula, his supporters, and many mainstream media outlets have characterized the conviction as a baseless and politically motivated prosecution. That Justice Toffoli, a Lula appointee, issued this sweeping ruling—and also issued a broad and highly political statement condemning the entire Car Wash operation—would certainly seem consistent with the notion that the ruling had more to do with political and personal motivations than the law. Worse still, the ruling not only invalidates the Odebrecht plea deal and all other convictions that relied on the evidence it produced, but the ruling also calls for the investigation of the Car Wash prosecutors and judges for (alleged) misconduct.

Now, it is worth noting that Justice Toffoli’s ruling is unlikely to have any effect on Odebrecht’s plea agreement with the U.S. authorities. U.S. evidentiary standards tend to be more permissive, at least in this context, about barring the use of illegally sourced evidence – especially in cases where the public interest has clearly been aggrieved. And Odebrecht is unlikely to try to use the Brazilian ruling to wriggle out of is plea deal with the U.S., especially since that deal provides that non-compliance can result in further prosecution.

One more observation may be pertinent here: The Brazilian prosecutors may have hurt their cause by not providing sufficient transparency in an official register of the crimes, including their investigation, prosecution, and ultimate plea bargain. In the U.S., the Department of Justice website provides open and transparent information about all Foreign Corrupt Practices Act plea agreements. In the case of Odebrecht, company representatives signed affidavits testifying to US$788 million in bribes to government officials in 12 countries, including US$349 million in Brazil. In all, ill-gotten gains netted Odebrecht US$3.336 billion of construction contracts, including US$1.9 billion in Brazil. By contrast, Brazilian authorities failed to provide the transparency required under Brazilian law. The Federal Public Prosecutor, which handles civil and criminal cases, disclosed nothing until, following last week’s decision, it posted the agreement’s legal framework. The Office of the Comptroller General, which handles administrative crimes, posts all plea bargains on its website but includes few to no specific details about crimes.

The issue of transparency raises a counterfactual question: to what extent would things have been different if the facts of the Odebrecht case had been made transparent, engraving outrageous corruption permanently on the public record from the very beginning? Just maybe Justice Toffoli’s decision might have been different. Transparency affects the legal and political environment in unmeasurable ways, and may have impacted subsequent judicial rulings.
