The highest US court, without comment, let stand a December 2014 US court of appeals ruling that reversed the convictions of Todd Newman of Diamondback Capital Management and Anthony Chiasson of Level Global Investors, two hedge fund figures targeted in the government's multi-year crackdown on insider trading.
A three-judge panel of the appeals court said Newman and Chiasson were too far away from the original leak of insider information and may not have realized the information, which came from corporate insiders at Dell and Nvidia, was obtained improperly and not through legitimate industry analysis.
The appeals court ruling was a major blow to the insider-trading crackdown led by President Barack Obama's administration, and particularly to the efforts of US Attorney Preet Bharara in New York City, who had a lengthy winning streak on prominent cases including figures from the hedge funds Galleon and SAC Capital.
The Obama administration in July filed a petition for a writ of certiorari to reconsider the appeals decision, saying it conflicted with Supreme Court precedent and that the ruling would cheat legitimate financial analysts and investors and create "an obvious roadmap for unscrupulous insiders and tippees."
