As I noted in a post at the time, last Fall, the U.S. Supreme Court in the Macquarie Infrastructure Corporation v. Moab Partners, L.P. case agreed to take up the question of whether whether the failure to make disclosure required by Item 303 of Reg. S-K is an actionable omission under Section 10(b) and Rule 10b-5. In January, the Court heard oral argument in the case. In the following guest post, Sarah Eichenberger and Jonathan Rotenberg, Partners in the Securities Litigation practice at the Katten law firm, discuss the questions the Justices as asked the oral argument and assess the possible outcomes of the case, as well as the potential significance of the outcomes. I would like to thank Sarah and Jonathan for allowing me to publish their article as a guest post on this site. I welcome guest post submissions from responsible authors on topics of interest to this site’s readers. Please contact me directly if you would like to submit a guest post.

The U.S. Supreme Court has agreed to take up a case in which the court will be asked to address the recurring question of whether the failure to make disclosure required by Item 303 of Reg. S-K is an actionable omission under Section 10(b) and Rule 10b-5. The Court apparently agreed to take up the case due to a split between the Circuits on the question of whether or not an Item 303 violation can be actionable. Because allegations based on alleged Item 303 violations are a frequent feature of securities class action complaints, the Court’s ruling in the case could potentially be significant. A copy of the Court’s September 29, 2023, order granting the petitioners’ petition for a writ of certiorari in the cases, Macquarie Infrastructure Corporation v. Moab Partners, L.P., can be found here.Continue Reading Supreme Court to Consider Whether Item 303 Violations are Actionable under Section 10(b)

supreme courtThe U.S. Supreme Court has agreed to take up a case that will address a recurring issue that has arisen in the securities class action litigation arena – that is, whether or not the alleged failure to make a disclosure required by Item 303 of Reg. S-K is an actionable omission under Section 10(b) and Rule 10b-5. A circuit split has emerged on this issue, with the Second Circuit holding that Item 303 does create an actionable duty of disclosure, while the Ninth and Third Circuits have held that it does not. The Court’s grant of the writ of certiorari in the case of Leidos, Inc. v. Indiana Public Retirement System will afford the Court an opportunity to resolve the circuit split and to address the question of whether Item 303 creates an actionable disclosure duty. The U.S. Supreme Court’s March 27, 2017 order granting the writ of certiorari can be found here.

fifcirsealA recurring question arising in class action securities litigation is what constitutes a “corrective disclosure” for purposes of satisfying the requirements for pleading loss causation. In the Amedisys securities class action litigation, the district court had examined the five partial disclosures on which the plaintiff sought to rely to establish loss causation and held
