Servotronics, Inc. V. Rolls-Royce Plc And The Boeing Company: Brief Of Professor Yanbai Andrea Wang As Amicus Curiae In Support Of Neither Party, Yanbai Andrea Wang, Michael H. Mcginley

All Faculty Scholarship

Rather than expressing a view on the issues raised and ably briefed by the parties, amicus submits this brief to inform the Court of the scholarly research she has conducted regarding Section 1782 proceedings since this Court’s seminal decision in Intel. As Section 1782 applications have proliferated, the lower courts have struggled to apply the Intel factors as this Court had envisioned. Especially in the context of Section 1782 applications submitted by parties to an international proceeding (as opposed to those made by the international tribunal itself), lower courts have frequently found themselves unable to analyze and apply the …

Event studies, a half-century-old approach to measuring the effect of events on stock prices, are now ubiquitous in securities fraud litigation. In determining whether the event study demonstrates a price effect, expert witnesses typically base their conclusion on whether the results are statistically significant at the 95% confidence level, a threshold that is drawn from the academic literature.

The Pleading Problem In Antitrust Cases And Beyond, Herbert J. Hovenkamp

All Faculty Scholarship

In its Twombly decision the Supreme Court held that an antitrust complaint failed because its allegations did not include enough “factual matter” to justify proceeding to discovery. Two years later the Court extended this new pleading standard to federal complaints generally. Twombly’s broad language has led to a broad rewriting of federal pleading doctrine.

Naked market division conspiracies such as the one pled in Twombly must be kept secret because antitrust enforcers will prosecute them when they are detected. This inherent secrecy, which the Supreme Court did not discuss, has dire consequences for pleading if too much factual specificity …
