The Commission's administrative law judges (ALJs) include the Chief Administrative Law Judge (Chief ALJ), additional ALJs, and support staff. The primary role of our ALJs is to conduct the trial phase of Commission investigations under section 337 of the Tariff Act of 1930 (19 U.S.C. 1337). The Chief ALJ assigns the investigation to one of the ALJs, who rules on motions during the trial stage. After the trial, the ALJ makes an initial determination as to whether a violation of section 337 exists, and makes findings of fact and law and recommendations as appropriate.
