Charles Hill and other respondents challenged Securities and Exchange Commission administrative proceedings in federal district court, including the constitutionality of the agency’s administrative law judges and the administrative review process. The district court exercised jurisdiction and entered preliminary injunctions. The Eleventh Circuit held that the securities statute provided an exclusive route for review: the respondents had to present their claims in the administrative proceedings and then seek review in the appropriate federal court of appeals. The statutory scheme was broad enough to encompass their constitutional challenges, so the existence of constitutional questions did not permit parallel district-court litigation. Because the district court lacked jurisdiction, the Eleventh Circuit vacated the preliminary injunction orders and remanded with instructions to dismiss the cases. The court did not decide the merits of the constitutional challenges or invalidate the agency’s proceedings.
