Continue ReadingThe New (Old) Presumption Against Extraterritoriality
The reach of U.S. law keeps changing. For decades—in fact, off and on for more than a century—U.S. courts have turned to the presumption against extraterritoriality to determine the geographic scope of federal statutes. When the presumption changes, so does the reach of U.S. law. And the presumption has changed a lot lately. Most recently,…
Continue ReadingTwo New Supreme Court Decisions on the Presumption Against Extraterritoriality
The end of the Supreme Court’s term brought two decisions on the presumption against extraterritoriality, a significant and contested interpretive canon for federal statutes. Yegiazaryan v. Smagin ruled 6-3 that a civil RICO suit based on an alleged scheme to fraudulently conceal assets belonging to a U.S. judgment debtor had sufficient domestic content to fit…

Today, it is “well established” that U.S. antitrust law applies extraterritorially to foreign conduct that causes substantial effects in the United States, but this was not always true. When the Supreme Court first addressed the geographic scope of the Sherman Act in 1909, it held that the act applied only to conduct in the United…

The Ninth Circuit opinion in Gonzalez v. Google (2021) raises important questions about how the presumption against extraterritoriality applies to immunity defenses invoked by social media companies under 47 U.S.C. § 230.Section 230 shields internet companies from civil liability for user-generated content hosted on their platforms. Gonzalezholds, effectively, that there is no conceivable application of…
Continue ReadingState Presumptions Against Extraterritoriality Apply to State Statutes
At TLB, we write a lot about extraterritoriality in general and about the federal presumption against extraterritoriality in particular. For the last three decades, the federal presumption has been the principal tool that courts have used to determine the geographic scope of federal statutes. But what if the statute in question is a state statute?…

Extraterritoriality has been on the outs with the Roberts Court, which has curtailed the reach of U.S. trademark, human rights, securities, and racketeering laws via the presumption against extraterritoriality. But globally, extraterritoriality may be on the rise. Countries have flexed their extraterritorial muscles to address data privacy, human rights, competition law, tax base erosion, and…

In Motorola Solutions, Inc. v. Hytera Communications Corp. Ltd., the Seventh Circuit recently addressed the extraterritorial reach of two federal intellectual property statutes, the Defend Trade Secrets Act (DTSA) and the Copyright Act. The court held that the DTSA does apply extraterritorially and allowed recovery on that basis. The court, however, rejected the recovery of…

In Morrison v. National Australia Bank (2010), the U.S. Supreme Court applied the presumption against extraterritoriality to § 10(b) of the Securities Exchange Act, holding that this provision applies only to transactions in the United States. Morrison’s transactional test has proven difficult to apply to unlisted securities that do not trade on an exchange. In…

The presumption against extraterritoriality is the principal tool that U.S. courts use to determine the reach of federal statutes. Last year, in Abitron Austria GmbH v. Hetronic International, Inc. (2023), the U.S. Supreme modified the presumption by requiring conduct relevant to a provision’s focus to occur in the United States in order for the application…
