The Tenth Circuit upheld an extraterritorial application of U.S. securities law under the Dodd-Frank Act. The SEC alleged that Defendants, operating from within the United States, ran a Ponzi scheme in which 90% of the fraudulent securities sales were to victims overseas. On interlocutory appeal from an asset freeze and other preliminary relief, Defendants argued that the antifraud provisions of the Securities Act do not apply to the alleged overseas sales. The Tenth Circuit disagreed, holding that, under Dodd-Frank, the antifraud provisions apply “when either significant steps are taken in the United States to further a violation of those antifraud provisions or conduct outside the United States has a foreseeable substantial effect within the United States.” 913 F.3d 1204, 1212 (10th Cir. 2019).
