In 1983, Switzer was sued by the U.S. Securities and Exchange Commission (SEC) for an alleged civil violation of the laws prohibiting "insider trading" of securities. He defended himself as having innocently overheard the information while lounging on the bleacher behind some corporate insiders—at a stadium where Switzer was watching his elder son compete in a track meet. The case was tried in Oklahoma City United States District Court (before a special U.S. District Judge appointed from Kansas). The case was dismissed at the conclusion of the Government's case for its failure to demonstrate that there had been any purposeful disclosure to Switzer.
