Following a decision by a Board of Discipline, the accused, the District Advisory Board, or those who sign the charges shall be entitled to appeal the decision to the General Court of Appeals for those in the United States and Canada, or to the Regional Court of Appeals in other global regions. The appeal shall be begun within 30 days after such decision, and the court shall review the entire record of the case and all steps that have been taken therein. If the court discovers any substantial error prejudicial to the right of any person, it shall correct such error by ordering a new hearing to be conducted in a manner capable of giving relief to that person affected adversely by previous proceedings or decision.
