Background

Brett Mauri appealed his convictions for money laundering in violation of Section eighteen thousand five hundred seventy of Title eighteen of the United States Code. He argued the statute was unconstitutionally vague and that his money laundering convictions should merge with his wire fraud convictions.

The court’s reasoning

The court reviewed the constitutionality of the statute de novo. It found that the language of the statute provided adequate notice to Mauri that engaging in large financial transactions with funds he knew were derived from crime was illegal. The court noted that Mauri engaged in two transactions involving more than ten thousand dollars in funds from his own fraud scheme. Regarding the merger argument, the court held that the money laundering was not a central component of the criminal scheme, which was to attract clients for custom home projects. The court also rejected the double jeopardy challenge, stating the statutes involve different elements.

What it means going forward

The decision reinforces that defendants with actual notice of statutory prohibitions cannot claim vagueness, and that money laundering charges may stand separately from fraud charges when the laundering is not central to the scheme.
