In brief
Overview
According to Petitioners, the case presents two disparate views of the loss required to sustain a securities‑fraud claim under the Reform Act.
According to Mr. Hungar, petitioners argue that loss causation requires the plaintiff to demonstrate that the inflation attributable to the misrepresentation has been removed or reduced through corrective information to the market.
Respondents contend that Section 9(b) of the Reform Act does not apply to materiality, loss causation, or damages, and that recovery is only possible if the inflation is taken out of the stock.
Background and question before the Court
According to Petitioners, the case presents two disparate views of what kind of loss is necessary to sustain a claim for securities fraud under the Reform Act's loss‑causation requirement.
Justice Kennedy asked whether, had certiorari not been granted, the Ninth Circuit’s opinion would have become final and what would have happened on remand and in the trial court.
According to Justice O'Connor, justice O'Connor questioned whether the general pleading rule governing complaints was adequate for securities‑fraud cases.
What each side argues
Petitioners
According to Mr. Hungar, petitioners argue that loss causation requires the plaintiff to show that the inflation attributable to the misrepresentation has been removed or reduced through corrective information to the market.
According to William F. Sullivan, damages must be the result of the misrepresentation, not of other factors.
According to Mr. Sullivan, the loss‑causation codification in the Reform Act is meaningful and creates a pleading standard that must be satisfied at the time of filing.
According to Mr. Sullivan, the Reform Act’s loss‑causation requirement provides defendants a meaningful opportunity to respond, serving as a screen for frivolous securities‑fraud claims.
Respondents
According to Mr. Cooughlin, section 9(b) of the Reform Act applies only to fraud itself and not to materiality, loss causation, or damages.
According to Mr. Couglin, recovery is possible only if the inflation is taken out of the stock, which constitutes recoverable damages under Ninth Circuit law.
