Administrative law judges are bound by the Code of Judicial Conduct, as contained in Rule 501 of the South Carolina Appellate Court Rules. The sole grounds for discipline and sanctions for administrative law judges are those contained in the Code of Judicial Conduct in Rule 502, Rule 7 of the South Carolina Appellate Court Rules. The State Ethics Commission, which is responsible for enforcement and administration of those rules shall use the procedure contained in Section 8-13-320. Notwithstanding another provision of law, an administrative law judge and the judge's spouse or guest may accept an invitation to attend a judicial-related or bar-related function, or an activity devoted to the improvement of the law, legal system, or the administration of justice.
