The U.S. Supreme Court recently held that the anti-fraud provision of the Securities Exchange Act does not prohibit “pure omissions,” but only false statements or misleading half-truths.  The unanimous decision in Macquarie Infrastructure Corp. v. Moab Partners, L.P. (April 12, 2024) holds that § 10(b) of the Exchange Act and the SEC’s Rule 10b-5(b) require a statement that is false or misleading.  A pure omission that does not render a statement false or misleading is not actionable, at least in private actions.

The Second Circuit held today that putative securities class actions involving transactions in non-U.S.-listed securities require careful scrutiny to determine whether the class members’ claims can be litigated on a classwide basis. The court’s ruling in In re Petrobras Securities (No. 16-1914) will likely increase the difficulty of certifying securities…

The U.S. Supreme Court’s decision yesterday in Merrill Lynch v. Manning clarified the scope of federal jurisdiction under the Exchange Act in certain important respects, but also left open critical issues that may arise in future cases.  Although the Court rejected federal jurisdiction in resolving the sole issue that was before it, the Court also stated that federal courts might well have jurisdiction over state law claims that “necessarily raise” substantial issues under federal law.

The decision, however, provides little guidance as to how that standard may be applied. Future cases involving securities trading, and the extensive body of federal regulation governing that activity, may well require future courts to determine that issue.

On May 16, 2016, the U.S. Supreme Court ruled that the provision of the Securities Exchange Act of 1934 granting federal district courts exclusive jurisdiction over suits brought to enforce the Exchange Act is subject to the same jurisdictional test established by the general federal-question jurisdictional statute. The Court held in Merrill Lynch v. Manning that, under both statutes, the question is whether the case “arises under a federal law.” The Court thus rejected the defendants’ effort to remove a case from state court by asserting a broader theory of federal jurisdiction under the Exchange Act.
