Fifty-five years after the decision of Securities and Exchange Commission v. Texas Gulf Sulphur, Inc., a distinguished panel of national experts considered the impact of this landmark case on insider trading – past, present and future at a symposium on September 29 at Quinnipiac School of Law.

This symposium was presented by the Quinnipiac School of Law and Quinnipiac Law Review and co-sponsored by the Securities and Exchange Commission Historical Society, the Connecticut Bar Association, and the New York Bar Association. Quinnipiac Professor Marilyn Ford produced the symposium.

Panel 1

The panel focuses on the Texas Gulf Sulphur litigation and its importance to the historical development of the insider trading prohibition arising under the antifraud provisions of the federal securities laws. It also discusses early judicial hostility to the use of common law fraud as well as the changes that led to the Second Circuit’s determination in 1968 that the securities trading by certain Texas Gulf officers, directors and employees violated SEC Rule 10b-5. It then explores some of the events that culminated in the four U.S. Supreme Court decisions that continue to define insider trading law’s contours right up to the present day: Chiarella v. United States (1980), Dirks v. SEC (1983), Carpenter v. United States (1987) and United States v. O’Hagan (1997).
