"A LARGE TROVE of documents furnished exclusively to The Intercept Brasil reveals serious ethical violations and legally prohibited collaboration between the judge and prosecutors who last year convicted and imprisoned former Brazilian President Luiz InĂ¡cio Lula da Silva on corruption charges — a conviction that resulted in Lula being barred from the 2018 presidential election. These materials also contain evidence that the prosecution had serious doubts about whether there was sufficient evidence to establish Lula’s guilt."
