28 U.S.C. § 2071 : US Code - Section 2071: Rule-making power generally

      (a) The Supreme Court and all courts established by Act of
    Congress may from time to time prescribe rules for the conduct of
    their business. Such rules shall be consistent with Acts of
    Congress and rules of practice and procedure prescribed under
    section 2072 of this title.
      (b) Any rule prescribed by a court, other than the Supreme Court,
    under subsection (a) shall be prescribed only after giving
    appropriate public notice and an opportunity for comment. Such rule
    shall take effect upon the date specified by the prescribing court
    and shall have such effect on pending proceedings as the
    prescribing court may order.
      (c)(1) A rule of a district court prescribed under subsection (a)
    shall remain in effect unless modified or abrogated by the judicial
    council of the relevant circuit.
      (2) Any other rule prescribed by a court other than the Supreme
    Court under subsection (a) shall remain in effect unless modified
    or abrogated by the Judicial Conference.
      (d) Copies of rules prescribed under subsection (a) by a district
    court shall be furnished to the judicial council, and copies of all
    rules prescribed by a court other than the Supreme Court under
    subsection (a) shall be furnished to the Director of the
    Administrative Office of the United States Courts and made
    available to the public.
      (e) If the prescribing court determines that there is an
    immediate need for a rule, such court may proceed under this
    section without public notice and opportunity for comment, but such
    court shall promptly thereafter afford such notice and opportunity
    for comment.
      (f) No rule may be prescribed by a district court other than
    under this section.
