The Clearing House Association joined SIFMA, NYSE, and the Chamber of Commerce in an amicus brief in City of Pontiac Policemen’s & Firemen’s Retirement System v. UBS AG, a case presently pending in the federal appeals court in New York. The case involves an attempt by the plaintiffs to sue the defendants under the federal securities laws for actions that occurred overseas. The sole ground for jurisdiction would be that the defendants are cross-listed on a U.S. exchange. The brief takes the position that a recent Supreme Court decision bars such actions.
