U.S. Chamber files amicus brief

September 10, 2015

The U.S. Chamber filed a merits-stage amicus brief in the U.S. Supreme Court in a case addressing whether Section 27 of the Exchange Act of 1934 provides federal jurisdiction over state-law claims seeking to establish liability based on violations of the Act and its regulations.

The Chamber’s amicus brief argues that Section 27 extends federal jurisdiction to all suits alleging violations of the Act and its implementing regulations or seeking to enforce duties created by the Act. It explains that uniformity in the application of the Act is critical for effective enforcement of the securities laws and efficient administration of financial markets. According to the brief, the Third Circuit’s decision to the contrary encourages artful pleading and creates substantial risk of inconsistency in the application of the securities laws.

Matthew T. Martens, Jaclyn Moyer, and John Byrnes of Wilmer Cutler Pickering Hale and Dorr LLP served as co-counsel for the U.S. Chamber of Commerce on behalf of the U.S. Chamber Litigation Center.
