After a circuit split on the constitutionality of the Securities and Exchange Commission’s in-house judges, Gibson, Dunn & Crutcher partner Mark Perry is taking the question to the U.S. Supreme Court.

Perry filed a petition for writ of certiorari Friday on behalf of his client, financial investor Raymond Lucia. The petition asks the court to settle a circuit split over whether the hiring process for the SEC’s administrative law judges is constitutional. While the U.S. Court of Appeals for the Tenth Circuit ruled against the SEC last year, the D.C. Circuit ruled for it in the Lucia case.
