Mark Perry, on behalf of the petitioners, argued that the judgment below represented nothing less than a frontal assault on the Supreme Court’s earlier rulings in Central Bank of Denver, NA v. First Interstate Bank of Denver, NA, 511 US 164 (1994) (holding a private plaintiff may not bring a suit for aiding and abetting under § 10(b) of the Securities Exchange Act of 1934) and Stoneridge Inv. Partners v. Scientific-Atlanta, 128 S. Ct. 761 (2008) (holding that there is no implied right of action under § 10(b) against customers/suppliers because investors did not rely on their statements).
