As a recent crime, consideration will initially be given to the eo iter concepts of money laundering, as well as the kind of evidence, indicative evidence is killed. The discussion then turns on the use of evidence by indentionof the previous offence as substantive evidence to be subsidised by criminal conviction for crimede Law 9.613/1990. Looking at decisions in the case-law, the development of the legal and judicial thinking brought about by this institution is demonstrated. Commentary on defensive arguments is being made in academia, specifically on the principles of broad defence and legality. Finally, there is no doubt that it is perfectly lawful to use evidence of the previous offence to subsidise a criminal conviction for money laundering offences, since these are municipal offences (precedent and washing), with specific legal provisions, and because they are fully in line with the Brazilian criminal procedure system.
