United States v. Mangus, No. 21-0158 (D.D.C. 2023)
United States v. Mangus is a landmark case that underscores the challenges in enforcing international environmental law against private individuals engaged in illegal activities that have transboundary effects.
Can the United States prosecute a citizen for violations of international environmental law when the illegal activity occurred in a foreign country, but the impacts have transboundary effects?
Under the Lacey Act, the United States can enforce violations against its citizens who engage in illegal activities that contravene both domestic and international laws, including those occurring outside US borders if they have an environmental impact.
The court held that Mangus could be prosecuted under the Lacey Act for his role in the illegal deforestation activities, affirming the United States' ability to enforce international environmental laws domestically.
United States v. Mangus is significant because it illustrates the potential for domestic legal systems to enforce international environmental norms. It emphasizes the US government's dedication to using domestic statutes like the Lacey Act to tackle environmental crimes that have global implications. For law students, this case is a key example of how international environmental obligations can translate into domestic legal action. Furthermore, it demonstrates the increasing importance of cooperation between nations in prosecuting environmental crimes.
