In a scathing decision by the United States District Court for the Southern District of New York, the Court denied class certification of the Allergan securities class action (“Allergan”). See In re Allergan PLC Sec. Litig., 2020 U.S. Dist. LEXIS 179371 (S.D.N.Y Sept. 29, 2020).

The August 20, 2020 decision in In re: Volkswagen “Clean Diesel” Mktg., Sales Practices, and Prods. Liab. Litig., MDL No. 2672 CRB (JSC) by the United States District Court for the Northern District of California (“the Opinion”), dismissing a significant portion of the SEC’s federal securities claims against Volkswagen as having been previously released by the DOJ, serves as an important reminder for why such coordination is important and how defendants may take advantage of the failure to coordinate, as did Volkswagen.

The U.S. Court of Appeals for the Ninth Circuit (“Ninth Circuit”) will soon be presented the opportunity to address the novel question of whether investors who purchase a security in the context of a direct listing, rather than an initial public offering (“IPO”), have standing to bring claims under Sections 11 and 12(a)(2) of the Securities Act of 1933, despite the fact that such investors cannot allege that they purchased shares registered under and traceable to a defective registration statement.

Over the past several weeks, the Firm has received a number inquiries from clients (on both coasts) who are interested in manufacturing or selling test kits, respirators, masks, and other PPE in response to the COVID-19 pandemic, with respect to potential liability risks associated with such activities.

Recently, the United States District Court for the Central District of California denied the defendants’ motion to dismiss the Second Amended Complaint (“Amended Complaint”) filed in the Toshiba securities litigation. As we previously wrote, in 2016, the district court dismissed the case, holding both that transactions in Toshiba’s unsponsored American Depositary Receipts (ADRs) are not “domestic” transactions as required by Morrison, and also that the plaintiffs’ Japanese law claims must be dismissed due to comity concerns and on forum non conveniens grounds. (link to prior blog). Then, in 2018, the Ninth Circuit reversed this decision, holding that Toshiba ADR trades are domestic, and allowed the defendants to file the Amended Complaint asserting more specific allegations about Toshiba’s connection to the ADR trades. (link to blog on 9th Circuit opinion).

On November 1, 2019, the United States Court of Appeals for the Second Circuit issued a summary order rejecting the appeal of an objector to the Foreign Exchange Antitrust Settlement. A few weeks earlier, U.S. District Court Judge Schofield had denied a motion filed by the objector and class counsel seeking an “indicative ruling” on their combined motion for approval of an agreement that would have ended the appeal. These two decision clear the way for the remaining distribution from the settlement fund, which totaled over $2.3 billion dollars.

Last week, the district court entered an order, granting CalSTRS’ motion for intervention for the limited purpose of tolling the statute of repose. While there is no longer a risk that the complaint will be dismissed (the vast majority of Plaintiffs’ claims have since survived dismissal), CalSTRS has successfully preserved its right to opt out if a class is certified. Allowing CalSTRS (and others) to use motions to intervene to toll the statute of repose rather than forcing such putative class members to choose to forego their rights or file their own opt-out action may preserve resources and encourage efficiency of the courts.

Years after Plaintiffs brought a federal securities complaint against Petrobras, and more than a year after the case settled for approximately $3 billion, Judge Jed S. Rakoff of the United States District Court for the Southern District of New York ordered the unsealing of the majority of documents attached to parties’ summary judgment papers. Cornell University intends to use these documents in an arbitration in Brazil. Not only does Judge Rakoff’s decision come as an important reminder that sealing orders are not intended to last forever, but this decision also demonstrates how a motion to unseal may be used to bypass the traditional requirements of 28 U.S.C. § 1782, frequently invoked by entities seeking to use U.S. discovery in foreign proceedings.
