In addition, he chairs the Institutional Investor Class Action Recovery practice which has recovered nearly $7 billion for thousands of mutual funds and other institutional clients.

Peter is one of the nation’s leading securities litigators and he has represented clients in well over 100 cases, investigations, and proceedings throughout the country. He has successfully defended SEC investigations, class actions, derivative suits, stock exchange proceedings, and state securities investigations, and has handled numerous FINRA arbitrations, among other matters.

Peter has recovered over $7 billion for institutional clients. He has represented various clients in opting out of or objecting to proposed class settlements and has represented institutions as plaintiffs in various actions. In this role he participates in virtually every securities action that is filed and thus has a unique perspective when representing clients in said cases.

Second Circuit Summarily Affirms the Attorneys’ Fees Award in the Foreign Exchange Antitrust Settlement after District Court Rejects Class Counsel’s Side Deal with the Objector

December 2, 2019 | Blog | By Joel Rothman

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.

The U.S. Supreme Court denied defendants-appellees’ petition for certiorari in Hagan v. Khoja. As set forth in our prior alert, the executives of the now-defunct biotechnology company, Orexigen, sought review of a Ninth Circuit decision, which not only created a departure from other courts in its narrow-approach to incorporation by reference and judicial notice, but according to the petition, also distinguished itself by being the first Circuit Court of Appeal to find that an issuer owes a duty to update a statement of historical fact that was accurate when made. At issue was whether Orexigen had a duty to disclose data that demonstrated interim results from an obesity drug trial were not as promising as once touted. In opposition to the petition for certiorari, respondent argued, inter alia, that “[e]ven if petitioners were correct . . . that this case implicates whether companies have a duty to update earlier statements of historical fact, the interlocutory posture of this case would make it the worst kind of vehicle for considering that question.”

In the Traffic Monsoon litigation, the U.S. Court of Appeals for the Tenth Circuit held that the enforcement provisions of the Securities Act and the Exchange Act reach Traffic Monsoon’s sales to customers outside of the United States. The implications of this decision are significant. This is the first Circuit Court decision to interpret Section 929P(b) of Dodd-Frank, and the first to adopt the position that Dodd-Frank limited Morrison’s application to allow for the enforcement provisions of the 1933 and 1934 Acts to apply extraterritorially. As a result, the decision may result in future decisions by the SEC to allow for holders of common shares to be eligible for recovery in connection with fair funds, rather than limiting eligible parties to holders of shares of American Depositary Shares or Receipts (ADR’s), a limitation the SEC imposed in the Fair Fund established for investors in BP. Recently, Traffic Monsoon has requested a stay of the Tenth Circuit's mandate while it prepares a writ of certiorari to the Supreme Court.

The United States District Court of the District of Connecticut will soon decide whether a putative class member may intervene “for the limited purpose of tolling the statute of repose.” Statutes of repose place an outer limit on when a claim can be brought. For example, claims brought under Sections 11 and 12 of the Securities Act of 1933 are subject to a 3-year statute of repose, 15 U.S.C. § 77m, and claims brought under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 are subject to a 5-year statute of repose. 15 U.S.C. § 1658. Less than two-years ago, the U.S. Supreme Court held that unlike statutes of limitations, which may be tolled by the pendency of a class action, statutes of repose cannot be so equitably tolled. CALPERS v. ANZ Securities. Should the District Court deny the motion, the putative class member, who purchased millions of Teva shares during the proposed class period will be time-barred from opting-out of the securities class action at-issue or asserting its own claims should the action be dismissed.

Last week, executives of the now-defunct biotechnology company, Orexigen filed a petition for certiorari before the U.S. Supreme Court, seeking clarification of the duty to update under the federal securities laws. The petition seeks further review of a recent decision by the Ninth Circuit, Khoja v. Orexigen Therapeutics, Inc., 899 F.3d 988 (9th Cir. 2018), which not only created a departure from other courts in its narrow-approach to incorporation by reference and judicial notice, but according to Orexigen, also distinguished itself from other Circuit Courts by being the first Circuit Court to find that an issuer owes a duty to update a statement of historical fact that was accurate when made. Specifically, the Ninth Circuit held that “by touting and publishing the ‘surprisingly’ positive 25 percent interim results [of the drug at-issue’s ability to decrease cardiovascular events], Orexigen created its own obligation to report that those results did not pan out after all” as evidenced by the 50 percent interim results.

In 2017, courts across this country were split on whether plaintiffs could assert a class action alleging claims under the Securities Act of 1933 (which provides a private right of action against issuers and others for providing false or misleading statements in offering materials) in state court. While California state courts recognized such jurisdiction, in New York, similar suits were routinely removed to federal court. In the midst of this jurisdictional uncertainty and prior to launching their respective initial public offerings, Blue Apron Holdings, Roku Inc., and Stitch Fix, Inc. adopted charter-based Federal Forum Provisions, in an attempt to make federal district courts the exclusive forum for the resolution of any complaint asserting claims arising under the Securities Act.

On August 15, 2018, Judge Jed S. Rakoff of the U.S. District Court for the Southern District of New York awarded an objector to the Petrobras class settlement nearly $12,000 in attorneys’ fees (click here for the Order). The objector had asked the Court for almost $200,000 to cover 231.7 hours of legal work. Approximately one month later, Judge Rakoff sanctioned another objector to the Petrobas class settlement (click here for the Order). In the September Order, Judge Rakoff issued a grave warning to future objectors and reminded counsel that it is the Court’s duty to “safeguard the ability of objectors to protect class members from abusive settlements while in turn protect[] class members from being abused by the objectors themselves.
