On 29 December 1992, when the trial began in the Federal Senate, Collor resigned in a letter read out by lawyer José Moura Rocha to avoid impeachment.

[1][2][3] During the political campaign for the 1989 elections, Paulo César Farias was treasurer of the presidential team of Fernando Collor de Mello and Itamar Franco.

[4][5] The 1989 presidential election, the first after the promulgation of the 1988 Federal Constitution, resulted in the victory of Fernando Collor de Mello (PRN-AL) over Luiz Inácio Lula da Silva (PT-SP).

In contrast, Lula presented himself to the population as an expert on workers' problems, especially because of his experience in the trade union movement, and supported the strong presence of the state in the economy.

During the inquiry process, Ana Acioli, Collor's secretary, and Francisco Eriberto, his former driver, testified to the commission, confirming the accusations and giving details of the scheme.

In the indictment, Aristides Junqueira, Prosecutor General of the Republic, claimed that Collor used fake accounts to receive Cr$ 4.384.122.689,00 directly from companies linked to PC Farias.

Other evidence collected from the files stored on PC's computer was also annulled after Collor's lawyer team invoked the doctrine of the fruit of the poisonous tree.

In practice, the ministers' interpretation is that the crime could only be established when there was proof of the anticipation, omission or delay of a functional act due to an advantage received.

According to Célio Silva, former advisor general of the Republic and Collor's lawyer, the 1992 impeachment process could not even have been initiated, as there is no law establishing the rules for judging crime of liability.
