Understanding Causation in Private Securities Lawsuits: Building on Amgen

With Amgen, the Supreme Court’s majority once again holds that inquiry into the alleged market impact of a misrepresentation is not required to invoke fraud on the market approach to causation so that the class can be certified. Rather than just leaving matters where they have been since the Supreme Court’s muddled encounter with causation in Basic Inc. v. Levinson, the Supreme Court’s most recent decision appears to relax some earlier-held tenets with respect to markets believed sufficiently efficient for fraud on the market to be invoked. This Article not only identifies the central flaw of Basic that has over the decades distorted applications of fraud on the market but also suggests how, building on Amgen, what the future focus should be in considering whether a suit can proceed as a class action based on fraud on the market

How Understanding the Nature of Corporate Norms Can Prevent Their Destruction by Settlements

Scholars have long celebrated the importance of norms in corporate law. Indeed, norms likely guide corporate actors more than the omnipresent threat of shareholder suits. This Article divides corporate norms into two distinct groups: aspirational norms and arbiter norms. Aspirational norms announce socially desirable objectives for corporate managers and encourage certain disclosure practices; arbiter norms identify distinct transactions for closer scrutiny by an independent body, the court. This Article shows that even though aspirational norms and arbiter norms serve different objectives, they share a common characteristic—overbreadth. This feature exists whether the norm is set forth by statute or found in judicial doctrine. Such overbreadth explains some, but by no means all, of the problems accompanying shareholder litigation, including the frequency of suits and inconsequential settlements. This Article also develops the paradoxes that accompany corporate norms. The inherent overbreadth of both aspirational and arbiter norms can be of great assistance to their protection against inconsequential settlements. Using the recent decision In re Trulia, Inc. Stockholder Litigation, this Article addresses how courts can fulfill their role in the non-adversarial setting of the settlement hearing. When asked to approve a settlement, the court should anchor its scrutiny of the adequacy and reasonableness of a settlement in the norm that is central to the suit. By doing so, the court can more positively contribute to the ongoing development of corporate norms
