Royal Bank of Scotland signs are seen at a branch of the bank, in London, Britain December 1, 2017. RBS agreed to settle Justice Department and FHFA investigations over its sales of residential mortgage-backed securities in the run-up to the financial crisis. The SEC did not pursue its own action against RBS in this instance. The petition Hong filed on Monday asks the Supreme Court to consider what constitutes an "action" within the SEC's whistleblower incentive program. "The better a whistleblower's information, the larger the sanctions, the larger the whistleblower award, and the greater the self-interested motivation for the SEC to take enforcement actions that it has conveniently placed outside of Dodd-Frank's reach," it added.
