Title 5 › PART I — THE AGENCIES GENERALLY › CHAPTER 5 — ADMINISTRATIVE PROCEDURE › SUBCHAPTER II — ADMINISTRATIVE PROCEDURE › § 555
Agencies must follow these rules unless another part of the same law says otherwise. If someone is required to appear in person before an agency, they can bring and be advised by a lawyer or, if the agency allows, another qualified representative. People may appear in person or with a representative to present or resolve issues, as long as the agency can keep business orderly. Agencies must try to finish matters brought to them within a reasonable time, considering the parties’ needs. The law does not create or deny a right for non-lawyers to represent others. Agencies may only demand reports, inspections, or investigations if the law allows it. If you are required to give data or evidence, you can keep or, by paying lawful costs, get a copy or transcript, except in a nonpublic investigatory hearing where you may be limited to inspecting the official transcript for good cause. Agency subpoenas (legal orders to appear or produce evidence) that the law allows must be issued on request and, when rules require, after showing the request is generally relevant and reasonably limited. If a subpoena is challenged, a court will uphold it if it follows the law and can order compliance within a reasonable time and punish refusal. If an agency denies a written request, it must give prompt notice and, unless the denial just repeats an earlier one or is obvious, include a short explanation.
