Amicus Briefs

Petrobras Securities Litigation


U.S. Supreme Court
(petition for writ of cert.)

Amicus Issue:
Whether the court violated Halliburton II, misapplied the burden of proof, and erred by relieving plaintiffs in the Second Circuit of any burden of showing that there was a price impact of news on the defendant’s stock price. Whether a class may be certified in the absence of proof that an administratively feasible means exists by which the putative class member (and the court and defendants) can determine whether he or she is a member of the class.

Counsel of Record:
