Opinion for the court filed by Circuit Judge RUTH BADER GINSBURG.
Appellant Thomas J. Ward is a United States citizen whose extradition is sought by the United Kingdom. In this action for a writ of prohibition, Ward contends that Article III and the Fifth Amendment command that his extradition proceedings be conducted by an Article III judge, not by a magistrate. The district court upheld the constitutionality of the statute (18 U.S.C. § 3184) and the local rule (D.D.C. Rule 501(a)(5)) that expressly authorize magistrates to preside over international extradition proceedings. We affirm the district court’s judgment.
I.
In keeping with United States-United Kingdom treaty prescriptions, the United Kingdom, in July 1989, requested the extradition of appellant Ward. Ward is wanted in Great Britain for trial on British Theft Act charges stemming from his alleged role in an illegal scheme to support the price of Guinness PLC stock during a 1986 takeover battle. Pursuant to 18 U.S.C. § 3184 and D.D.C. Rule 501(a)(5), the district court assigned the extradition complaint to a magistrate for hearing and decision. Ward both moved in the extradition proceeding and commenced this collateral action to establish his alleged right to a hearing before a district judge rather *287 than a magistrate. The magistrate stayed the scheduled extradition hearing pending district court resolution of Ward’s collateral action.
Denying Ward’s petition, the district judge first observed that the statutory authority of the magistrate is unambiguous. Under 18 U.S.C. § 3184, “any magistrate authorized so to do by a court of the United States” may issue a warrant for the arrest of a fugitive, and preside over and decide international extradition proceedings. The pertinent local rule, D.D.C. Rule 501(a)(5), provides that a magistrate appointed by the court pursuant to 28 U.S.C. § 631 “shall have the duty and power to ... [cjonduct international extradition proceedings.” There can be no genuine dispute about the plain meaning of the relevant statute and rule. 1 We therefore turn to the constitutionality of assigning extradition requests to a United States magistrate.
II.
Through extradition proceedings, one nation turns over custody of a person at the request of another nation, pursuant to a treaty between the two nations.
See generally
Restatement (ThiRd) of The Foreign Relations Law of the United States §§ 475, 478 (1987). The purpose of an extradition hearing is to determine whether “the evidence [is] sufficient to sustain the charge under the provisions of the proper treaty or convention.” 18 U.S.C. § 3184. As the district court emphasized, “ ‘[a]n extradition hearing is not the occasion for an adjudication of guilt or innocence.’ ”
Messina v. United States,
Article III, the mainstay of appellant’s challenge, provides that the “judicial Power of the United States, shall be vested in one supreme Court and in such inferior Courts as the Congress may from time to time ordain and establish.” It further provides that such courts shall be staffed by judges who hold office during good behavior and whose compensation shall not be diminished during tenure in office. Article III “safeguards the role of the Judicial Branch in our tripartite system by barring congressional attempts ‘to transfer jurisdiction [to non-Artiele III tribunals] for the purpose of emasculating’ constitutional courts.”
Commodity Futures Trading Comm’n v. Schor,
*288
Ward’s core argument, however, emphasizes the “personal” safeguard of Article III,
i.e.,
the “right to have claims decided by judges who are free from potential domination by other branches of government.”
United States v. Will,
An extradition hearing, as we earlier observed, and underscore as crucial to our decision, is akin to a preliminary examination, a proceeding customarily handled by magistrates.

Furthermore, as the government highlights, actions taken by magistrates in international extradition matters are subject to habeas corpus review by an Article III district judge, with appellate review available thereafter.
See, e.g., In re Burt,
The Supreme Court long ago explained that an international extradition proceeding
is not to be regarded as in the nature of a final trial by which the prisoner could be convicted or acquitted of the crime charged against him, but [is] rather of the character of those preliminary examinations which take place every day in this country before an examining or committing magistrate for the purpose of determining whether a case is made out which will justify the holding of the accused ... to ultimately answer to an indictment, or other proceeding, in which he shall be finally tried upon the charge made against him.
Benson v. McMahon,
Conclusion
Article III of the Constitution is not offended by the federal statute and district court rule under which the matter of Ward’s extradition to the United Kingdom has been assigned to a magistrate. The district court, therefore, correctly denied Ward’s petition for a writ of prohibition. The judgment of that court is accordingly
Affirmed.
Notes
. We note that, in addition to authorizing magistrates to conduct extradition hearings, 18 U.S.C. § 3184 qualifies as competent to conduct extradition proceedings "any judge of a court of record of general jurisdiction of any State.” Such judges, who may be elected or hold fixed terms of appointment, of course, do not hold Article III offices.
. Insofar as there may be limits to the power of Congress to create non-Artiele III tribunals
within the judiciary, see Northern Pipeline Constr. Co. v. Marathon Pipe Line Co.,
Among the factors upon which we have focused are the extent to which the "essential attributes of judicial power” are reserved to Article III courts, and, conversely, the extent to which the non-Article III forum exercises the range of jurisdiction and powers normally vested only in Article III courts, the origins and importance of the right to be adjudicated, and the concerns that drove Congress to depart from the requirements of Article III.
. In contrast,
Gomez v. United States,
. We further note that Ward’s case is hardly analogous
to Ng Fung Ho v. White,
. Ward contends he is not receiving the "process" he is "due” because of the assignment of his extradition case to a magistrate instead of an Article III judge. As the government points out, this asserted Fifth Amendment due process objection has no independent grounding. Cf. Fallon, Of Legislative Courts, Administrative Agencies, and Article III, 101 Harv.L.Rev. 916, 978-79 n. 341 (1988) ("Nearly every question about the necessity of jurisdiction in an article III court could be reduced to a due process question.”).
