In its landmark 2010 decision in Morrison v. National Australia Bank, the Supreme Court articulated what seemed to be a bright-line test for determining the extent to which the U.S. securities laws apply to transactions with international elements. In so doing, the Court harshly rejected the fact-intensive “conduct/effects” tests propounded several decades ago by the Second Circuit and followed by many other courts throughout the country.

Last week, the Second Circuit got its revenge. In a long-awaited decision in ParkCentral Global Hub Limited v. Porsche Automobile Holdings SE, the court declined “to proffer a test that will reliably determine when a particular invocation of [the Securities Exchange Act’s anti-fraud provision] will be deemed appropriately domestic or impermissibly extraterritorial.” Instead, the Second Circuit held that courts must carefully consider the facts and circumstances of each case to avoid the very result that the Supreme Court had hoped to prevent in Morrison: promiscuous application of the U.S. securities laws to transactions that have little, if any, relationship to the United States.

The ParkCentral decision illustrates the difficulties that the Morrison test created for determining whether U.S. law should apply to transactions involving unlisted securities and international elements. The decision reinforces the trend against extraterritorial application of U.S. law – while perhaps not closing the door to applying U.S. law where facts so warrant.
