Justice Sonia Sotomayor

On April 12, 2023, in a short, unanimous opinion written by Justice Sonja Sotomayor, the U.S. Supreme Court held that a failure to disclose information required under Item 303 of Regulation S-K is, standing alone, not an actionable omission under Section 10(b) of the Exchange Act and Rule 10b-5 thereunder. The Supreme Court said that in the absence of affirmative statement that is rendered misleading by the omission, an Item 303 violation alone is not sufficient to state a claim under Rule 10b-5. As the Supreme Court opinion put it in summarizing its decision, “pure omissions are not actionable under Rule 10b–5.” The Court’s opinion in Macquarie Infrastructure Corp. v. Moab Partners L.P. can be found here.Continue Reading U.S. Supreme Court: Item 303 Omissions Alone Not Actionable

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.

As I discussed in a recent post (here), the Ninth Circuit recently reversed in part the district court’s dismissal of the Google+ user data-related securities class action lawsuit. One feature of the decision that perhaps did not attract as much attention is the appellate court’s reversal of district court’s dismissal of the plaintiff’s scheme liability claims. In the following guest post, Bruce Vanyo and Jonathan Rotenberg discuss the significance of the scheme liability portion of the Ninth Circuit’s opinion. Bruce and Jonathan are partners in the Securities Litigation practice at Katten Muchin Rosenman LLP, resident in the New York office.

In the following guest post, Partners Brooke Cucinella and Michael Osnato, Counsel Anar Rathod Patel, and Associate Rebecca Sussman, all of the Simpson Thacher law firm, analyze the bill and discuss its implications. A version of this article was previously published as a Simpson Thacher client memorandum. I would like to thank the authors for allowing me to publish their article as a guest post on this site.

In its 2011 decision in the Janus Group case, the U.S. Supreme Court held that one who does not “make” a false statement cannot be held liable under section (b) of Rule 10b-5. In an enforcement action brought against him by the SEC, the defendant, Francis Lorenzo, argued that under the Janus case, he could not be held liable under the securities laws for forwarding a misleading email his boss had written because he did not “make” the false statement. The case ultimately made its way to the U.S. Supreme Court. On March 27, 2019, the Court found that even if Lorenzo could not be held liable under section (b) of the Rule because he did not “make” the statement, he could still be held liable under the scheme liability provisions in sections (a) and (c) of the Rule for disseminating the  document. The Court’s March 27, 2019 opinion in Lorenzo v. Securities and Exchange Commission can be found here.
