4/ As DEF has said through its past advocacy, prosecuting developers of noncustodial p2p software under 18 U.S.C. § 1960 for operating “unlicensed money transmitting businesses,” in legally incorrect and unfair. The DOJ pushing a radical new theory of criminal liability via criminal indictment, and in direct contravention of 2019 FinCEN Guidance, violates Due Process and fair notice principles, and makes the U.S. less competitive.

3/ Lewellen asserts a Declaratory Judgment Act (DJA) claim, asking the court to declare that he is not operating a "money transmitting" business and that he is not a "money transmitter," a First Amendment claim "that the money-transmitting laws are unconstitutional insofar as they apply to Lewellen’s writing and publishing of non-custodial and immutable software,” and a Fifth Amendment claim that the DOJ's interpretation of the money transmitting laws violates his Due Process rights.

2/ First, a refresher on what this case is all about.

In Jan. 2025, Michael Lewellen filed a preemptive lawsuit against the DOJ for unfairly prosecuting noncustodial software developers as operators of money transmitting businesses under 18 U.S.C. §1960, the federal criminal statute which proscribes failing to register a “money transmitting business.”

The key issue contemplated in this case is whether Lewellen, in his plan to publish a DeFi protocol, engages in an unlawful activity under 18 U.S.C. §1960.
