§631. Appointment and tenure

(a) The judges of each United States district court and the district courts of the Virgin Islands, Guam, and the Northern Mariana Islands shall appoint United States magistrate judges in such numbers and to serve at such locations within the judicial districts as the Judicial Conference may determine under this chapter. In the case of a magistrate judge appointed by the district court of the Virgin Islands, Guam, or the Northern Mariana Islands, this chapter shall apply as though the court appointing such a magistrate judge were a United States district court. Where there is more than one judge of a district court, the appointment, whether an original appointment or a reappointment, shall be by the concurrence of a majority of all the judges of such district court, and when there is no such concurrence, then by the chief judge. Where the conference deems it desirable, a magistrate judge may be designated to serve in one or more districts adjoining the district for which he is appointed. Such a designation shall be made by the concurrence of a majority of the judges of each of the district courts involved and shall specify the duties to be performed by the magistrate judge in the adjoining district or districts.

(b) No individual may be appointed or reappointed to serve as a magistrate judge under this chapter unless:

(1) He has been for at least five years a member in good standing of the bar of the highest court of a State, the District of Columbia, the Commonwealth of Puerto Rico, the Territory of Guam, the Commonwealth of the Northern Mariana Islands, or the Virgin Islands of the United States, except that an individual who does not meet the bar membership requirements of this paragraph may be appointed and serve as a part-time magistrate judge if the appointing court or courts and the conference find that no qualified individual who is a member of the bar is available to serve at a specific location;

(2) He is determined by the appointing district court or courts to be competent to perform the duties of the office;

(3) In the case of an individual appointed to serve in a national park, he resides within the exterior boundaries of that park, or at some place reasonably adjacent thereto;

(4) He is not related by blood or marriage to a judge of the appointing court or courts at the time of his initial appointment; and

(5) He is selected pursuant to standards and procedures promulgated by the Judicial Conference of the United States. Such standards and procedures shall contain provision for public notice of all vacancies in magistrate judge positions and for the establishment by the district courts of merit selection panels, composed of residents of the individual judicial districts, to assist the courts in identifying and recommending persons who are best qualified to fill such positions.

(c) A magistrate judge may hold no other civil or military office or employment under the United States: Provided, however, That, with the approval of the conference, a part-time referee in bankruptcy or a clerk or deputy clerk of a court of the United States may be appointed and serve as a part-time United States magistrate judge, but the conference shall fix the aggregate amount of compensation to be received for performing the duties of part-time magistrate judge and part-time referee in bankruptcy, clerk or deputy clerk: And provided further, That retired officers and retired enlisted personnel of the Regular and Reserve components of the Army, Navy, Air Force, Marine Corps, and Coast Guard, members of the Reserve components of the Army, Navy, Air Force, Marine Corps, and Coast Guard ¹ members of the Space Force, and members of the Army National Guard of the United States, the Air National Guard of the United States, and the Naval Militia and of the National Guard of a State, territory, or the District of Columbia, except the National Guard disbursing officers who are on a full-time salary basis, may be appointed and serve as United States magistrate judges.

(d) Except as otherwise provided in sections 375 and 636(h) of this title, no individual may serve under this chapter after having attained the age of seventy years: Provided, however, That upon a majority vote of all the judges of the appointing court or courts, which is taken upon the magistrate judge's attaining age seventy and upon each subsequent anniversary thereof, a magistrate judge who has attained the age of seventy years may continue to serve and may be reappointed under this chapter.

(e) The appointment of any individual as a full-time magistrate judge shall be for a term of eight years, and the appointment of any individuals as a part-time magistrate judge shall be for a term of four years, except that the term of a full-time or part-time magistrate judge appointed under subsection (k) ² shall expire upon-

(1) the expiration of the absent magistrate judge's term,

(2) the reinstatement of the absent magistrate judge in regular service in office as a magistrate judge,

(3) the failure of the absent magistrate judge to make timely application under subsection (j) ¹ of this section for reinstatement in regular service in office as a magistrate judge after discharge or release from military service,

(4) the death or resignation of the absent magistrate judge, or

(5) the removal from office of the absent magistrate judge pursuant to subsection (i) of this section,

whichever may first occur.

(f) Upon the expiration of his term, a magistrate judge may, by a majority vote of the judges of the appointing district court or courts and with the approval of the judicial council of the circuit, continue to perform the duties of his office until his successor is appointed, or for 180 days after the date of the expiration of the magistrate judge's term, whichever is earlier.

(g) Each individual appointed as a magistrate judge under this section shall take the oath or affirmation prescribed by section 453 of this title before performing the duties of his office.

(h) Each appointment made by a judge or judges of a district court shall be entered of record in such court, and notice of such appointment shall be given at once by the clerk of that court to the Director.

(i) Removal of a magistrate judge during the term for which he is appointed shall be only for incompetency, misconduct, neglect of duty, or physical or mental disability, but a magistrate judge's office shall be terminated if the conference determines that the services performed by his office are no longer needed. Removal shall be by the judges of the district court for the judicial district in which the magistrate judge serves; where there is more than one judge of a district court, removal shall not occur unless a majority of all the judges of such court concur in the order of removal; and when there is a tie vote of the judges of the district court on the question of the removal or retention in office of a magistrate judge, then removal shall be only by a concurrence of a majority of all the judges of the council. In the case of a magistrate judge appointed under the third sentence of subsection (a) of this section, removal shall not occur unless a majority of all the judges of the appointing district courts concur in the order of removal; and where there is a tie vote on the question of the removal or retention in office of a magistrate judge, then removal shall be only by a concurrence of a majority of all the judges of the council or councils. Before any order or removal shall be entered, a full specification of the charges shall be furnished to the magistrate judge, and he shall be accorded by the judge or judges of the removing court, courts, council, or councils an opportunity to be heard on the charges.

(j) Upon the grant by the appropriate district court or courts of a leave of absence to a magistrate judge entitled to such relief under chapter 43 of title 38, such court or courts may proceed to appoint, in the manner specified in subsection (a) of this section, another magistrate judge, qualified for appointment and service under subsections (b), (c), and (d) of this section, who shall serve for the period specified in subsection (e) of this section.

(k) A United States magistrate judge appointed under this chapter shall be exempt from the provisions of subchapter I of chapter 63 of title 5.

1948 Act

Based on title 28, U.S.C., 1940 ed., §§526 and 527, sections 27, 66, 80e, 100, 117e, 129, 172, 198e, 204e, 256d, 395e, 403c–5, 403h–5, 404c–5, and 408m of title 16, U.S.C., 1940 ed., Conservation, and section 863 of title 48, U.S.C., 1940 ed., Territories and Insular Possessions (May 27, 1894, ch. 72, §5, 28 Stat. 74 ; May 28, 1896, ch. 252, §§19, 20, 29 Stat. 184 ; Apr. 12, 1900, ch. 191, §34, 31 Stat. 84 ; Mar. 2, 1901, ch. 814, 31 Stat. 956 ; Mar. 3, 1911, ch. 231, §291, 36 Stat. 1167 ; Jan. 7, 1913, ch. 6, 37 Stat. 648 ; Aug. 22, 1914, ch. 264, §6, 38 Stat. 700 ; June 30, 1916, ch. 197, §6, 39 Stat. 245 ; Aug. 21, 1916, ch. 368, §6, 39 Stat. 523 ; Mar. 2, 1917, ch. 145, §41, 39 Stat. 965 ; June 2, 1920, ch. 218, §§7, 8, 41 Stat. 733 ; Mar. 4, 1921, ch. 161, §1, 41 Stat. 1412 ; Dec. 13, 1926, ch. 6, §1, 44 Stat. 919 ; Apr. 25, 1928, ch. 434, §6, 45 Stat. 460 ; Apr. 26, 1928, ch. 438, §6, 45 Stat. 464 ; Mar. 2, 1929, ch. 583, §6, 45 Stat. 1538 ; Apr. 19, 1930, ch. 200, §6, 46 Stat. 228 ; June 25, 1935, ch. 309, §1, 49 Stat. 422 ; Aug. 19, 1937, ch. 703, §5, 50 Stat. 702 ; Mar. 26, 1938, ch. 51, §2, 52 Stat. 118 ; June 25, 1938, ch. 684, §1, 52 Stat. 1164 ; June 28, 1938, ch. 778, §1, 52 Stat. 1213 ; Mar. 4, 1940, ch. 40, §2, 54 Stat. 43 ; Mar. 6, 1942, ch. 150, §5, 56 Stat. 134 ; Mar. 6, 1942, ch. 151, §5, 56 Stat. 137 ; Apr. 29, 1942, ch. 264, §5, 56 Stat. 260 ; June 5, 1942, ch. 341, §5, 56 Stat. 318 ; Dec. 28, 1945, ch. 592, 59 Stat. 659 , 660; Apr. 23, 1946, ch. 202, §1, 60 Stat. 119 , 120).

Section consolidates section 526 and a portion of 527, both of title 28, U.S.C., 1940 ed., with provisions of sections 27, 66, 80e, 100, 117e, 129, 172, 198e, 204e, 256d, 395e, 403c–5, 403h–5, 404c–5 and 408m of title 16, U.S.C., 1940 ed., and provisions of section 863 of title 48, U.S.C., 1940 ed., Territories and Insular Possessions, relating to appointment of United States commissioners. For other provisions of said sections see Distribution Table.

Some of the provisions of section 863 of title 48, U.S.C., 1940 ed., Territories and Insular Possessions were retained in that title.

The provision of sections 395e, 403c–5, 404c–5, and 408m of title 16, U.S.C., 1940 ed., for appointment of the Park Commissioner in the Hawaii National Park, Shenandoah National Park, Great Smoky Mountains National Park, Mammoth Cave National Park and Isle Royale National Park upon "the recommendation of the Secretary of the Interior" was omitted as inconsistent not only with other provisions of this title but with other statutes applicable to other national parks.

All such park commissioners are United States commissioners and the revision of these sections makes possible uniformity and consistency in administrative matters concerning such commissioners. (See, also, sections 604 and 634 of this title.)

Words "the Director of the Administrative Office of the United States Courts" were substituted for "Attorney General" in section 526 of title 28, U.S.C., 1940 ed., in view of the general supervision by the Director over clerks and commissioners under section 601 et seq. of this title.

See, also, section 751 of this title prohibiting clerks from receiving compensation in another capacity.

First sentence of subsection (b) was substituted for the provision in section 527 of title 28, U.S.C., 1940 ed., prohibiting specified persons from acting as commissioners.

Words "at such places in the district as may be designated by the district court," in section 526 of title 28, U.S.C., 1940 ed., were omitted as unnecessary.

A provision in section 526 of title 28, U.S.C., 1940 ed., that commissioners should have the same powers and duties as are conferred and imposed by law, was omitted as superfluous.

The phrase in sections 526 and 527 of title 16, U.S.C., 1940 ed., "except as provided in section 591" and section 591, the effect of which was to except Alaska from this section, were omitted as unnecessary. This revised section by its terms limits the section and chapter 43 of this title to commissioners appointed by a "district court," which includes the courts enumerated in chapter 5 of this title but not those of Alaska, Canal Zone, or Virgin Islands.

Sections from title 16, U.S.C., 1940 ed., contained no tenure provisions.

Changes in phraseology were made.

Prior residence requirement for national park commissioners in section 635.-Based on sections 1a and 403c–9 of title 16, U.S.C., 1940 ed., Conservation (Aug. 19, 1937, ch. 703, §8, 50 Stat. 702 ; June 28, 1938, ch. 778, §1, 52 Stat. 1213 ).

Section consolidates section 1a with part of section 403c–9 of title 16, U.S.C., 1940 ed., relating to residence of a national park commissioner.

The provisions of sections 1a and 403c–9 of title 16, U.S.C., 1940 ed., relating to designation by the Secretary of the Interior of some place of residence reasonably adjacent to the park was modified by making such designation subject to the approval of the appointing court.

Senate Revision Amendment

By Senate amendment, "Big Bend" and "Crater Lake" were inserted in subsection (a) of this section, and section 158a of title 16, U.S.C., which was derived from act May 15, 1947, ch. 55, §1, 61 Stat. 91 , accordingly became an additional source of this section, such Act being included in the schedule of repeals. See 80th Congress Senate Report No. 1559.

As finally enacted, act May 15, 1947, ch. 57, 61 Stat. 92 , which amended section 403c–5 of title 16, U.S.C., became an additional source of this section and was accordingly included in the schedule of repeals by Senate amendment. See 80th Congress Senate Report No. 1559.

1949 Act

This amendment conforms the language of section 631(b) to the provisions of section 35 of the Bankruptcy Act, as amended by the act of June 28, 1946 (§3, 60 Stat. 324), that full-time referees in bankruptcy may not be appointed United States Commissioners.

This amendment also removes an ambiguity from section 631(b) by making it clear that the Director of the Administrative Office of the United States Courts has power to establish maximum limits of compensation to be received for performing the combined offices of commissioner and clerk or deputy clerk. This was the intent of sections 631 and 751 of title 28. (See the fifteenth paragraph of the reviser's note to the latter section, H. Rept. No. 308, April 25, 1947, p. A90, to accompany H.R. 3214, 80th Cong.)
