Morrison v. National Australia Bank, 561 U.S. 247 (2010), was a United States Supreme Court case concerning the extraterritorial effect of U.S. securities legislation. Morrison extinguished two species of securities class-action claims that had proliferated in preceding years: "foreign-cubed" claims, in which foreign plaintiffs sued foreign issuers for losses on transactions on foreign exchanges, and "foreign-squared" claims, brought by domestic plaintiffs against foreign issuers for losses on transactions on foreign exchanges.
