On behalf of Senate Majority Leader Mitch McConnell, Sen. Thad Cochran, Sen. John Boozman, and Sen. Richard Shelby, CCP (now IFS) filed this friend-of-the-court brief opposing a petition for a Writ of Mandamus filed in the U.S. Court of Appeals for the D.C. Circuit by Stephen M. Silberstein. Mr. Silberstein sought the writ to force the Securities and Exchange Commission (SEC) to engage in a rulemaking that would mandate corporate disclosure of otherwise-immaterial contributions to political organizations and industry groups. The Senators’ brief noted that such a rulemaking would directly violate the recent omnibus appropriations bill, which should be interpreted as preventing the SEC from regulating in that area. Two days after the filing of this amicus brief, Mr. Silberstein withdrew his petition.
