Macquarie Infrastructure

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. Here is Sarah and Jonathan’s article.Continue Reading Guest Post: Supreme Court Considers Whether Pure Omissions Can Support Section 10(b) Liability

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)
