Shareholder Plaintiffs Score a Class Certification Win from SCOTUS

On Wednesday, the Supreme Court issued its decision in Amgen, Inc. v. Connecticut Retirement Plans. In a 6-3 decision authored by Justice Ginsburg, the Supreme Court handed a win to plaintiffs in securities fraud class actions, holding that plaintiffs do not have to prove materiality at the class certification stage. The decision marks a departure from some of the Court’s more recent class action rulings, which seemed to narrow class action litigation. Justices Scalia, Thomas and Kennedy dissented.

In their complaint, plaintiff shareholders alleged that Amgen and its executives misled investors about the safety and efficacy of two anemia drugs, thereby violating Section 10(b) and Rule 10b-5. During class certification, Amgen argued that Rule 23(b)(3) required that plaintiffs needed to prove materiality in order to ensure that the questions of law or fact common to the class will “predominate over any questions affecting only individual members.” Both the district court and the Ninth Circuit Court of Appeals rejected Amgen’s argument. The Supreme Court followed suit, affirming the Court of Appeal’s judgment and holding that proof of materiality is not a prerequisite to class certification in securities fraud cases. Read More

Supreme Court To Hear Amgen’s Appeal of Class Cert

The Supreme Court will hear Amgen’s appeal in Amgen v. Connecticut Retirement Plans in the upcoming October term, the Court announced on Monday June 11. The lawsuit against Amgen alleges that the biotech company made misrepresentations about the safety of two anti-anemia drugs for US FDA-approved uses. In certifying the class, the Ninth Circuit held that plaintiff only needed to plausibly allege that Amgen’s misrepresentations were material based on a fraud-on-the-market theory for the class to be certified. Amgen’s appeal claims the district court must both require proof of materiality and allow Amgen to present evidence rebutting the fraud-on-the-market theory before certifying the class.
