Respondent, a citizen and resident of Mexico, was forcibly kidnaped from his home and flown by private plane to Texas, where he was arrested for his participation in the kidnaping and murder of a Drug Enforcement Administration (DEA) agent and the agent's pilot. After concluding that DEA agents were responsible for the abduction, the District Court dismissed the indictment on the ground that it violated the Extradition Treaty between the United States and Mexico (Extradition Treaty or Treaty), and ordered respondent's repatriation. The Court of Appeals affirmed. Based on one of its prior decisions, the court found that, since the United States had authorized the abduction, and since the Mexican Government had protested the Treaty violation, jurisdiction was improper.
The fact of respondent's forcible abduction does not prohibit his trial in a United States court for violations of this country's criminal laws. Pp. 3-15.

CHIEF JUSTICE REHNQUIST delivered the opinion of the Court.
The issue in this case is whether a criminal defendant, abducted to the United States from a nation with which it has an extradition treaty, thereby acquires a defense to the jurisdiction of this country's courts. We hold that he does not, and that he may be tried in federal district court for violations of the criminal law of the United States.
Respondent, Humberto Alyarez-Machain, is a citizen and resident of Mexico. He was indicted for participating in the kidnap and murder of United States Drug Enforcement Administration (DEA) special agent Enrique Camarena-Salazar and a Mexican pilot working with Camarena, Alfredo Zavala-Avelar. 1 The DEA believes that respondent, a medical doctor, participated in the murder by prolonging agent Camarena's life so that others could further torture and interrogate him. On April 2, 1990, respondent was forcibly kidnaped from his medical office in Guadalajara, Mexico, to be flown by private plane to El Paso, Texas, where he was arrested by DEA officials. The District Court concluded that DEA agents were responsible for respondent's abduction, although they were not personally involved in it. United States v. Caro-Quintero, 745 F.Supp. 599, 602-604, 609 (CD Cal. 1990). 2 [504 U.S. 655, 658]
Respondent moved to dismiss the indictment, claiming that his abduction constituted outrageous governmental conduct, and that the District Court lacked jurisdiction to try him because he was abducted in violation of the extradition treaty between the United States and Mexico. Extradition Treaty, May 4, 1978, 1979. United States-United Mexican States, 31 U.S.T. 5059, T.I.A.S. No. 9656 (Extradition Treaty or Treaty). The District Court rejected the outrageous governmental conduct claim, but held that it lacked jurisdiction to try respondent because his abduction violated the Extradition Treaty. The District Court discharged respondent and ordered that he be repatriated to Mexico. Caro-Quintero, supra, at 614.
The Court of Appeals affirmed the dismissal of the indictment and the repatriation of respondent, relying on its decision in United States v. Verdugo-Urquidez, 939 F.2d 1341 (CA9 1991), cert. pending, No. 91-670. 946 F.2d 1466 (1991). In Verdugo, the Court of Appeals held that the forcible abduction of a Mexican national with the authorization or participation of the United States violated the Extradition Treaty between the United States and Mexico. 3 Although the Treaty does not expressly prohibit such abductions, the Court of Appeals held that the "purpose" of the Treaty was violated by a forcible abduction, 939 F.2d, at 1350, which, along with a formal protest by the offended nation, would give a defendant the right to invoke the Treaty violation to defeat jurisdiction of the District Court to try him. 4 The Court of Appeals further held that the proper remedy for [504 U.S. 655, 659] such a violation would be dismissal of the indictment and repatriation of the defendant to Mexico.
In the instant case, the Court of Appeals affirmed the District Court's finding that the United States had authorized the abduction of respondent, and that letters from the Mexican Government to the United States Government served as an official protest of the Treaty violation. Therefore, the Court of Appeals ordered that the indictment against respondent be dismissed, and that respondent be repatriated to Mexico. 946 F.2d, at 1467. We granted certiorari, 502 U.S. 1024 (1992), and now reverse.
Although we have never before addressed the precise issue raised in the present case, we have previously considered proceedings in claimed violation of an extradition treaty and proceedings against a defendant brought before a court by means of a forcible abduction. We addressed the former issue in United States v. Rauscher, 119 U.S. 407 (1886); more precisely, the issue whether the Webster-Ashburton Treaty of 1842, 8 Stat. 572, 576, which governed extraditions between England and the United States, prohibited the prosecution of defendant Rauscher for a crime other than the crime for which he had been extradited. Whether this prohibition, known as the doctrine of specialty, was an intended part of the treaty had been disputed between the two nations for some time. Rauscher, 119 U.S., at 411 . Justice Miller delivered the opinion of the Court, which carefully examined the terms and history of the treaty; the practice of nations in regards to extradition treaties; the case law from the States; and the writings of commentators, and reached the following conclusion:
In Frisbie v. Collins, 342 U.S. 519 , rehearing denied, 343 U.S. 937 (1952), we applied the rule in Ker to a case in which the defendant had been kidnaped in Chicago by Michigan officers and brought to trial in Michigan. We upheld the conviction over objections based on the Due Process Clause and the federal Kidnaping Act, and stated:
In construing a treaty, as in construing a statute, we first look to its terms to determine its meaning. Air France v. Saks, 470 U.S. 392, 397 (1985); Valentine v. United States ex rel. Neidecker, 299 U.S. 5, 11 (1936). The Treaty says nothing about the obligations of the United States and Mexico to refrain from forcible abductions of people from the territory of the other nation, or the consequences under the Treaty if such an abduction occurs. Respondent submits that Article 22(1) of the Treaty, which states that it "shall apply to offenses specified in Article 2 [including murder] committed before and after this Treaty enters into force," 31 U.S.T., at 5073-5074, evidences an intent to make application of the Treaty mandatory for those offenses. However, the more natural conclusion is that Article 22 was included to ensure that the Treaty was applied to extraditions requested after the Treaty went into force, regardless of when the crime of extradition occurred. 10
More critical to respondent's argument is Article 9 of the Treaty, which provides:
We do not read the Treaty in such a fashion. Article 9 does not purport to specify the only way in which one country may gain custody of a national of the other country for the purposes of prosecution. In the absence of an extradition treaty, nations are under no obligation to surrender those in their country to foreign authorities for prosecution. Rauscher, 119 U.S., at 411 -412; Factor v. Laubenheimer, 290 U.S. 276, 287 (1933); cf. Valentine v. United States ex rel. Neidecker, supra, at 8-9 (United States may not extradite a citizen in the absence of a statute or treaty obligation). Extradition treaties exist so as to impose mutual obligations to surrender individuals in certain defined sets of circumstances, following established procedures. See 1 J. Moore, A Treatise on Extradition and Interstate Rendition 72 (1891). The Treaty thus provides a mechanism which would not otherwise exist, requiring, under certain circumstances, the United States and Mexico to extradite individuals to the [504 U.S. 655, 665] other country and establishing the procedures to be followed when the Treaty is invoked.
The history of negotiation and practice under the Treaty also fails to show that abductions outside of the Treaty constitute a violation of the Treaty. As the Solicitor General notes, the Mexican Government was made aware, as early as 1906, of the Ker doctrine, and the United States' position that it applied to forcible abductions made outside of the terms of the United States-Mexico Extradition Treaty. 11 Nonetheless, the current version of the Treaty, signed in 1978, does not attempt to establish a rule that would in any way curtail the effect of Ker. 12 Moreover, although language which would grant individuals exactly the right sought by respondent had been considered and drafted as early as [504 U.S. 655, 666] 1935 by a prominent group of legal scholars sponsored by the faculty of Harvard Law School, no such clause appears in the current Treaty. 13
Thus, the language of the Treaty, in the context of its history, does not support the proposition that the Treaty prohibits abductions outside of its terms. The remaining question, therefore, is whether the Treaty should be interpreted so as to include an implied term prohibiting prosecution where the defendant's presence is obtained by means other than those established by the Treaty. See Valentine, 299 U.S., at 17 ("Strictly, the question is not whether there had been a uniform practical construction denying the power, but whether the power had been so clearly recognized that the grant should be implied").
Respondent contends that the Treaty must be interpreted against the backdrop of customary international law, and that international abductions are "so clearly prohibited in international law" that there was no reason to include such a clause in the Treaty itself. Brief for Respondent 11. The international censure of international abductions is further evidenced, according to respondent, by the United Nations Charter and the Charter of the Organization of American States. Id., at 17. Respondent does not argue that these sources of international law provide an independent basis for the right respondent asserts not to be tried in the United States, but rather that they should inform the interpretation of the Treaty terms. [504 U.S. 655, 667]
The Court of Appeals deemed it essential, in order for the individual defendant to assert a right under the Treaty, that the affected foreign government had registered a protest. Verdugo, 939 F.2d, at 1357 ("In the kidnapping case, there must be a formal protest from the offended government after the kidnapping"). Respondent agrees that the right exercised by the individual is derivative of the nation's right under the Treaty, since nations are authorized, notwithstanding the terms of an extradition treaty, to voluntarily render an individual to the other country on terms completely outside of those provided in the treaty. The formal protest, therefore, ensures that the "offended" nation actually objects to the abduction, and has not in some way voluntarily rendered the individual for prosecution. Thus, the Extradition Treaty only prohibits gaining the defendant's presence by means other than those set forth in the Treaty when the nation from which the defendant was abducted objects.
This argument seems to us inconsistent with the remainder of respondent's argument. The Extradition Treaty has the force of law, and if, as respondent asserts, it is self-executing, it would appear that a court must enforce it on behalf of an individual regardless of the offensiveness of the practice of one nation to the other nation. In Rauscher, the Court noted that Great Britain had taken the position in other cases that the Webster-Ashburton Treaty included the doctrine of specialty, but no importance was attached to whether or not Great Britain had protested the prosecution of Rauscher for the crime of cruel and unusual punishment, as opposed to murder.
More fundamentally, the difficulty with the support respondent garners from international law is that none of it relates to the practice of nations in relation to extradition treaties. In Rauscher, we implied a term in the Webster-Ashburton Treaty because of the practice of nations with regard to extradition treaties. In the instant case, respondent [504 U.S. 655, 668] would imply terms in the Extradition Treaty from the practice of nations with regards to international law more generally. 14 Respondent would have us find that the Treaty acts as a prohibition against a violation of the general principle of international law that one government may not "exercise its police power in the territory of another state." Brief for Respondent 16. There are many actions which could be taken by a nation that would violate this principle, including waging war, but it cannot seriously be contended that an invasion of the United States by Mexico would violate the terms of the Extradition Treaty between the two nations. 15
In sum, to infer from this Treaty and its terms that it prohibits all means of gaining the presence of an individual [504 U.S. 655, 669] outside of its terms goes beyond established precedent and practice. In Rauscher, the implication of a doctrine of specialty into the terms of the Webster-Ashburton Treaty which, by its terms, required the presentation of evidence establishing probable cause of the crime of extradition before extradition was required, was a small step to take. By contrast, to imply from the terms of this Treaty that it prohibits obtaining the presence of an individual by means outside of the procedures the Treaty establishes requires a much larger inferential leap, with only the most general of international law principles to support it. The general principles cited by respondent simply fail to persuade us that we should imply in the United States-Mexico Extradition Treaty a term prohibiting international abductions.
Respondent and his amici may be correct that respondent's abduction was "shocking," Tr. of Oral Arg. 40, and that it may be in violation of general international law principles. Mexico has protested the abduction of respondent through diplomatic notes, App. 33-38, and the decision of whether respondent should be returned to Mexico, as a matter outside of the Treaty, is a matter for the Executive Branch. 16 We [504 U.S. 655, 670] conclude, however, that respondent's abduction was not in violation of the Extradition Treaty between the United States and Mexico, and therefore the rule of Ker v. Illinois is fully applicable to this case. The fact of respondent's forcible abduction does not therefore prohibit his trial in a court in the United States for violations of the criminal laws of the United States.
The judgment of the Court of Appeals is therefore reversed, and the case is remanded for further proceedings consistent with this opinion.
[ Footnote 2 ] Apparently, DEA officials had attempted to gain respondent's presence in the United States through informal negotiations with Mexican officials, but were unsuccessful. DEA officials then, through a contact in Mexico, offered to pay a reward and expenses in return for the delivery of respondent to the United States. United States v. Caro-Quintero, 745 F.Supp., at 602-604.
[ Footnote 3 ] Rene Martin Verdugo-Urquidez was also indicted for the murder of Agent Camarena. In an earlier decision, we held that the Fourth Amendment did not apply to a search by United States agents of Verdugo-Urquidez' home in Mexico. United States v. Verdug-Urquidez, 494 U.S. 259 (1990).
[ Footnote 4 ] The Court of Appeals remanded for an evidentiary hearing as to whether Verdugo's abduction had been authorized by authorities in the United States. United States v. Verdug-Urquidez, 939 F.2d, at 1362.
[ Footnote 5 ] Justice Gray, concurring, would have rested the decision on the basis of these Acts of Congress alone. Rauscher, 119 U.S., at 433 . Chief Justice Waite dissented, concluding that the treaty did not forbid trial on a charge other than that on which extradition was granted, and that the Acts of Congress did not change the "effect of the treaty." Id., at 436.
[ Footnote 6 ] Although the opinion does not explain why the messenger failed to present the warrant to the proper authorities, commentators have suggested that the seizure of Ker in the aftermath of a revolution in Peru provided the messenger with no "proper authorities" to whom the warrant could be presented. See Kester, Some Myths of United States Extradition Law, 76 Geo.L.J. 1441, 1451 (1988).
[ Footnote 7 ] In the words of Justice Miller, the treaty was not called into operation, was not relied upon, was not made the pretext of arrest, and the facts show that it was a clear case of kidnapping within the dominions of Peru, without any pretence of authority under the treaty or from the government of the United States. Ker v. Illinois, 119 U.S., at, 443.
Two cases decided during the Prohibition Era in this country have dealt with seizures claimed to have been in violation of a treaty entered into between the United States and Great Britain to assist the United States in off shore enforcement of its prohibition laws, and to allow British passenger ships to carry liquor while in the waters of the United States. 43 Stat. 1761 (1924). The history of the negotiations leading to the treaty is set forth in Cook v. United States, 288 U.S. 102, 111 -118 (1933). In that case, we held that the treaty provision for seizure of British vessels operating beyond the 3-mile limit was intended to be exclusive, and that therefore liquor seized from a British vessel in violation of the treaty could not form the basis of a conviction.
In Ford v. United States, 273 U.S. 593 (1927), the argument as to personal jurisdiction was deemed to have been waived.
[ Footnote 8 ] We have applied Ker to numerous cases where the presence of the defendant was obtained by an interstate abduction. See, e.g., Mahon v. Justice, 127 U.S. 700 (1888); Cook v. Harr, 146 U.S. 183 (1892); Pettibone v. Nichols, 203 U.S. 192, 215 -216 (1906).
[ Footnote 9 ] Ker also was not a national of Peru, whereas respondent is a national of the country from which he was abducted. Respondent finds this difference to be immaterial. Tr. of Oral Arg. 26.
[ Footnote 10 ] This interpretation is supported by the second clause of Article 22, which provides that [r]equests for extradition that are under process on the date of the entry into force of this Treaty shall be resolved in accordance with the provisions of the Treaty of 22 February, 1899, . . ." Extradition Treaty, May 4, 1978, 1979. United States United Mexican States, 31 U.S.T. 5059, 5074, T. I. A. S. No. 9656.
[ Footnote 11 ] In correspondence between the United States and Mexico growing out of the 1905 Martinez incident, in which a Mexican national was abducted from Mexico and brought to the United States for trial, the Mexican Charge wrote to the Secretary of State protesting that, as Martinez' arrest was made outside of the procedures established in the extradition treaty, "the action pending against the man cannot rest [on] any legal foundation." Letter of Balbino Davalos to Secretary of State, reprinted in Papers Relating to the Foreign Relations of the United States, H. R. Doc. No. 1, 59th Cong., 2d Sess., pt. 2, p. 1121 (1906). The Secretary of State responded that the exact issue raised by the Martinez incident had been decided by Ker, and that the remedy open to the Mexican Government, namely, a request to the United States for extradition of Martinez' abductor, had been granted by the United States. Letter of Robert Bacon to Mexican Charge, reprinted in Papers Relating to the Foreign Relations of the United States, H. R. Doc. No. 1, 59th Cong., 2d Sess., pt. 2, at 1121-1122.
Respondent and the Court of Appeals stress a statement made in 1881 by Secretary of State James Blaine to the Governor of Texas to the effect that the extradition treaty, in its form at that time, did not authorize unconsented to abductions from Mexico. Verdugo, 939 F.2d, at 1354; Brief for Respondent 14. This misses the mark, however, for the Government's argument is not that the Treaty authorizes the abduction of respondent, but that the Treaty does not prohibit the abduction.
[ Footnote 12 ] The parties did expressly include the doctrine of specialty in Article 17 of the Treaty, notwithstanding the judicial recognition of it in United States v. Rauscher, 119 U.S. 407 (1886). 31 U.S.T., at 5071-5072.
[ Footnote 13 ] In Article 16 of the Draft Convention on Jurisdiction with Respect to Crime, the Advisory Committee of the Research in International Law proposed:
[ Footnote 14 ] Similarly, the Court of Appeals in Verdugo reasoned that international abductions violate the "purpose" of the Treaty, stating that [t]he requirements extradition treaties impose constitute a means of safeguarding the sovereignty of the signatory nations, as well as ensuring the fair treatment of individuals. 939 F.2d, at 1350. The ambitious purpose ascribed to the Treaty by the Court of Appeals, we believe, places a greater burden on its language and history than they can logically bear. In a broad sense, most international agreements have the common purpose of safeguarding the sovereignty of signatory nations, in that they seek to further peaceful relations between nations. This, however, does not mean that the violation of any principle of international law constitutes a violation of this particular treaty.
[ Footnote 15 ] In the same category are the examples cited by respondent in which, after a forcible international abduction, the offended nation protested the abduction and the abducting nation then returned the individual to the protesting nation. Brief for Respondent 18, citing, inter alia, I Bassiouni, International Extradition: United States Law and Practice 5.4, pp. 235-237 (2d rev. ed. 1987). These may show the practice of nations under customary international law, but they are of little aid in construing the terms of an extradition treaty, or the authority of a court to later try an individual who has been so abducted. More to the point for our purposes are cases such as The Richmond, 9 Cranch 102 (1815), and The Merino, 9 Wheat. 391 (1824), both of which hold that a seizure of a vessel in violation of international law does not affect the jurisdiction of a United States court to adjudicate rights in connection with the vessel. These cases are discussed, and distinguished, in Cook v. United States, 288 U.S., at 122 .
[ Footnote 16 ] The Mexican Government has also requested from the United States the extradition of two individuals it suspects of having abducted respondent in Mexico, on charges of kidnaping. App. 39-66.
The advantage of the diplomatic approach to the resolution of difficulties between two sovereign nations, as opposed to unilateral action by the courts of one nation, is illustrated by the history of the negotiations leading to the treaty discussed in Cook v. United States, supra. The United States was interested in being able to search British vessels that hovered beyond the 3-mile limit and served as supply ships for motor launches, which took intoxicating liquor from them into ports for further distribution in violation of prohibition laws. The United States initially proposed that both nations agree to searches of the other's vessels beyond the 3-mile limit; Great Britain rejected such an approach, since it had no prohibition laws, and therefore no problem with United States vessels hovering just beyond its territorial waters. The parties appeared to be at loggerheads; then this Court decided Cunard S.S. Co. v. Mellon, 262 U.S. 100 (1923), holding that our prohibition laws applied to foreign merchant [504 U.S. 655, 670] vessels as well as domestic within the territorial waters of the United States, and that therefore the carrying of intoxicating liquors by foreign passenger ships violated those laws. A treaty was then successfully negotiated, giving the United States the right to seizure beyond the 3-mile limit (which it desired), and giving British passenger ships the right to bring liquor into United States waters so long as the liquor supply was sealed while in those waters (which Great Britain desired). Cook v. United States, supra.
JUSTICE STEVENS, with whom Justice BLACKMUN and Justice O'CONNOR join, dissenting.
The Court correctly observes that this case raises a question of first impression. See ante, at 3. The case is unique for several reasons. It does not involve an ordinary abduction by a private kidnaper, or bounty hunter, as in Ker v. Illinois, 119 U.S. 436 (1886); nor does it involve the apprehension of an American fugitive who committed a crime in one State and sought asylum in another, as in Frisbie v. Collins, 342 U.S. 519 (1952). Rather, it involves this country's abduction of another country's citizen; it also involves a violation of the territorial integrity of that other country, with which this country has signed an extradition treaty.
A Mexican citizen was kidnaped in Mexico and charged with a crime committed in Mexico; his offense allegedly violated both Mexican and American law. Mexico has formally [504 U.S. 655, 671] demanded on at least two separate occasions 1 that he be returned to Mexico, and has represented that he will be prosecuted and, if convicted, punished for his offense. 2 It is clear that Mexico's demand must be honored if this official abduction violated the 1978 Extradition Treaty between the United States and Mexico. In my opinion, a fair reading of the treaty in light of our decision in United States v. Rauscher, 119 U.S. 407 (1886), and applicable principles of international law, leads inexorably to the conclusion that the District Court, United States v. Caro-Quintero, 745 F.Supp. 599 (CD Cal. 1990), and the Court of Appeals for the Ninth Circuit, 946 F.2d 1466 (1991) (per curiam), correctly construed that instrument.
The extradition treaty with Mexico 3 is a comprehensive document containing 23 articles and an appendix listing the [504 U.S. 655, 672] extraditable offenses covered by the agreement. The parties announced their purpose in the preamble: the two governments desire "to cooperate more closely in the fight against crime and, to this end, to mutually render better assistance in matters of extradition." 4 From the preamble, through the description of the parties' obligations with respect to offenses committed within as well as beyond the territory of a requesting party, 5 the delineation of the procedures and evidentiary requirements for extradition, 6 the special [504 U.S. 655, 673] provisions for political offenses and capital punishment, 7 and other details, the Treaty appears to have been designed to cover the entire subject of extradition. Thus, Article 22, entitled "Scope of Application," states that the "Treaty shall apply to offenses specified in Article 2 committed before and after this Treaty enters into force," and Article 2 directs that [e]xtradition shall take place, subject to this Treaty, for willful acts which fall within any of [the extraditable offenses listed in] the clauses of the Appendix. 8 Moreover, as noted by the Court, ante, at 8, Article 9 expressly provides that neither contracting party is bound to deliver up its own nationals, although it may do so in its discretion, but if it does not do so, it "shall submit the case to its competent authorities for purposes of prosecution." 9
The Governments' claim that the Treaty is not exclusive, but permits forcible governmental kidnaping, would transform these, and other, provisions into little more than verbiage. For example, provisions requiring "sufficient" evidence to grant extradition (Art. 3), withholding extradition for political or military offenses (Art. 5), withholding extradition when the person sought has already been tried (Art. 6), withholding extradition when the statute of limitations for the crime has lapsed (Art. 7), and granting the requested Country discretion to refuse to extradite an individual who would face the death penalty in the requesting country (Art. 8), would serve little purpose if the requesting country could simply kidnap the person. As the Court of Appeals for the Ninth Circuit recognized in a related case, "[e]ach of these provisions would be utterly frustrated if a kidnapping were held to be a permissible course of governmental conduct." United States v. Verdugo-Urquidez, 939 F.2d 1341, 1349 (1991). In addition, all of these provisions only make sense if they are understood as requiring each treaty signatory to [504 U.S. 655, 674] comply with those procedures whenever it wishes to obtain jurisdiction over an individual who is located in another treaty nation. Id., at 1351.
It is true, as the Court notes, that there is no express promise by either party to refrain from forcible abductions in the territory of the other nation. See ante, at 9. Relying on that omission, 10 the Court, in effect, concludes that the Treaty merely creates an optional method of obtaining jurisdiction over alleged offenders, and that the parties silently reserved the right to resort to self-help whenever they deem force more expeditious than legal process. 11 If the United States, for example, thought it more expedient to torture or simply to execute a person rather than to attempt extradition, these options would be equally available, because they, too, were not explicitly prohibited by the Treaty. 12 [504 U.S. 655, 675] That, however, is a highly improbable interpretation of a consensual agreement 13 which, on its face, appears to have been intended to set forth comprehensive and exclusive rules concerning the subject of extradition. 14 In my opinion, "the manifest scope and object of the treaty itself," Rauscher, 119 U.S., at 422 , plainly imply a mutual undertaking to respect the territorial integrity of the other contracting party. That opinion is confirmed by a consideration of the "legal context" in which the Treaty was negotiated. 15 Cannon v. University of Chicago, 441 U.S. 677, 699 (1979).
In Rauscher, the Court construed an extradition treaty that was far less comprehensive than the 1978 Treaty with Mexico. The 1842 treaty with Great Britain determined the boundary between the United States and Canada, provided for the suppression of the African slave trade, and also [504 U.S. 655, 676] contained one paragraph authorizing the extradition of fugitives "in certain cases." 8 Stat. 576. In Article X, each nation agreed to "deliver up to justice all persons" properly charged with any one of seven specific crimes, including murder. 119 U.S., at 421 . 16 After Rauscher had been extradited for murder, he was charged with the lesser offense of inflicting cruel and unusual punishment on a member of the crew of a vessel on the high seas. Although the treaty did not purport to place any limit on the jurisdiction of the demanding state after acquiring custody of the fugitive, this Court held that he could not be tried for any offense other than murder. 17 Thus, the treaty constituted the exclusive means by which [504 U.S. 655, 677] the United States could obtain jurisdiction over a defendant within the territorial jurisdiction of Great Britain.
The Court noted that the treaty included several specific provisions, such as the crimes for which one could be extradited, the process by which the extradition was to be carried out, and even the evidence that was to be produced, and concluded that "the fair purpose of the treaty is that the person shall be delivered up to be tried for that offence, and for no other." Id., at 423. The Court reasoned that it did not make sense for the treaty to provide such specifics only to have the person pas[s] into the hands of the country which charges him with the offence, free from all the positive requirements and just implications of the treaty under which the transfer of his person takes place. Id., at 421. To interpret the treaty in a contrary way would mean that a country could request extradition of a person for one of the seven crimes covered by the treaty, and then try the person for another crime, such as a political crime, which was clearly not covered by the treaty; this result, the Court concluded, was clearly contrary to the intent of the parties and the purpose of the treaty.
Rejecting an argument that the sole purpose of Article X was to provide a procedure for the transfer of an individual from the jurisdiction of one sovereign to another, the Court stated:
Although the Court's conclusion in Rauscher was supported by a number of judicial precedents, the holdings in these cases were not nearly as uniform 19 as the consensus of international opinion that condemns one nation's violation of the territorial integrity of a friendly neighbor. 20 It is [504 U.S. 655, 679] shocking that a party to an extradition treaty might believe that it has secretly reserved the right to make seizures of citizens in the other party's territory. 21 Justice Story found it shocking enough that the United States would attempt to justify an American seizure of a foreign vessel in a Spanish port:
A critical flaw pervades the Court's entire opinion. It fails to differentiate between the conduct of private citizens, which does not violate any treaty obligation, and conduct expressly authorized by the Executive Branch of the Government, which unquestionably constitutes a flagrant violation of international law 27 and, in my opinion, also constitutes a breach of our treaty obligations. Thus, at the outset of its opinion, the Court states the issue as whether a criminal defendant, abducted to the United States from a nation with which it has an extradition treaty, thereby acquires a defense to the jurisdiction of this country's courts. Ante, at 1. That, of course, is the question decided in Ker v. Illinois, 119 U.S. 436 (1886); it is not, however, the question presented for decision today.
The importance of the distinction between a court's exercise of jurisdiction over either a person or property that has been wrongfully seized by a private citizen, or even by a state law enforcement agent, on the one hand, and the attempted exercise of jurisdiction predicated on a seizure by federal officers acting beyond the authority conferred by treaty, on the other hand, is explained by Justice Brandeis in his opinion for the Court in Cook v. United States, 288 U.S. 102 (1933). That case involved a construction of a Prohibition Era treaty with Great Britain that authorized American agents to board certain British vessels to ascertain whether they were engaged in importing alcoholic beverages. A [504 U.S. 655, 683] British vessel was boarded 111/2 miles off the coast of Massachusetts, found to be carrying unmanifested alcoholic beverages, and taken into port. The Collector of Customs assessed a penalty which he attempted to collect by means of libels against both the cargo and the seized vessel.
The Court held that the seizure was not authorized by the treaty, because it occurred more than 10 miles off shore. 28 The Government argued that the illegality of the seizure was immaterial, because, as in Ker, the court's jurisdiction was supported by possession, even if the seizure was wrongful. Justice Brandeis acknowledged that the argument would succeed if the seizure had been made by a private party without authority to act for the Government, but that a different rule prevails when the Government itself lacks the power to seize. Relying on Rauscher, and distinguishing Ker, he explained:
The Court's failure to differentiate between private abductions and official invasions of another sovereign's territory also accounts for its misplaced reliance on the 1935 proposal made by the Advisory Committee on Research in International Law. See ante, at 10, and n. 13. As the text of that proposal plainly states, it would have rejected the rule of the Ker case. 31 The failure to adopt that recommendation does not speak to the issue the Court decides today. The [504 U.S. 655, 686] Court's admittedly "shocking" disdain for customary and conventional international law principles, see ante, at 14, is thus entirely unsupported by case law and commentary.
As the Court observes at the outset of its opinion, there is reason to believe that respondent participated in an especially brutal murder of an American law enforcement agent. That fact, if true, may explain the Executive's intense interest in punishing respondent in our courts. 32 Such an explanation, however, provides no justification for disregarding the Rule of Law that this Court has a duty to uphold. 33 That the Executive may wish to reinterpret 34 the Treaty to [504 U.S. 655, 687] allow for an action that the Treaty in no way authorizes should not influence this Court's interpretation. 35 Indeed, the desire for revenge exerts "a kind of hydraulic pressure . . . before which even well settled principles of law will bend," Northern Securities Co. v. United States, 193 U.S. 197, 401 (1904) (Holmes, J., dissenting), but it is precisely at such moments that we should remember and be guided by our duty "to render judgment evenly and dispassionately according to law, as each is given understanding to ascertain and apply it." United States v. Mine Workers, 330 U.S. 258, 342 (1947) (Rutledge, J., dissenting). The way that we perform that duty in a case of this kind sets an example that other tribunals in other countries are sure to emulate.
The significance of this Court's precedents is illustrated by a recent decision of the Court of Appeal of the Republic of South Africa. Based largely on its understanding of the import of this Court's cases - including our decision in Ker - that court held that the prosecution of a defendant kidnaped by agents of South Africa in another country must be dismissed. S v. Ebrahim, S.Afr.L.Rep. (Apr.-June 1991). 36 The Court of Appeal of South Africa - indeed, I suspect most courts throughout the civilized world - will be deeply disturbed by the "monstrous" decision the Court announces today. For every nation that has an interest in preserving the Rule of Law is affected, directly or indirectly, by a [504 U.S. 655, 688] decision of this character. 37 As Thomas Paine warned, an "avidity to punish is always dangerous to liberty" because it leads a nation "to stretch, to misinterpret, and to misapply even the best of laws." 38 To counter that tendency, he reminds us:
[ Footnote 1 ] The abduction of respondent occurred on April 2, 1990. United States v. Caro-Quintero, 745 F.Supp. 599, 603 (CD Cal. 1990). Mexico responded quickly and unequivocally. Tr. of Oral Arg. 33; Brief for Respondent 3. On April 18, 1990, Mexico requested an official report on the role of the United States in the abduction, and on May 16, 1990, and July 19, 1990, it sent diplomatic notes of protest from the Embassy of Mexico to the United States Department of State. See Brief for United Mexican States as Amicus Curiae (Mexican Amicus) 5-6; App. to Mexican Amicus 1a-24a. In the May 16th note, Mexico said that it believed that the abduction. Id., at 9a-15a. was "carried out with the knowledge of persons working for the U.S. government, in violation of the procedure established in the extradition treaty in force between the two countries," App. to Mexican Amicus 5a, and in the July 19th note, it requested the provisional arrest and extradition of the law enforcement agents allegedly involved in the abduction. Id., at 9a-15a.
[ Footnote 2 ] Mexico has already tried a number of members involved in the conspiracy that resulted in the murder of the Drug Enforcement Administration agent. For example, Rafael Caro-Quintero, a coconspirator of Alyarez-Machain in this case, has already been imprisoned in Mexico on a 40-year sentence. See Brief for Lawyers Committee for Human Rights as Amicus Curiae 4.
[ Footnote 3 ] Extradition Treaty, May 4, 1978, 1979. United states-United Mexican States, 31 U.S.T. 5059, T.I.A.S. No. 9656 (Treaty or Extradition Treaty).
[ Footnote 4 ] Id., at 72. In construing a treaty, the Court has the "responsibility to give the specific words of the treaty a meaning consistent with the shared expectations of the contracting parties." Air France v. Saks, 470 U.S. 392, 399 (1985). It is difficult to see how an interpretation that encourages unilateral action could foster cooperation and mutual assistance - the stated goals of the Treaty. See also Presidential Letter of Transmittal attached to Senate Advice and Consent 3 (Treaty would "make a significant contribution to international cooperation in law enforcement").
Extradition treaties prevent international conflict by providing agreed-upon standards so that the parties may cooperate and avoid retaliatory invasions of territorial sovereignty. According to one writer, before extradition treaties became common, European states often granted asylum to fugitives from other states, with the result that a sovereign could enforce the return of fugitives only by force of arms. . . . Extradition as an inducement to peaceful relations and friendly cooperation between states remained of little practical significance until after World War I." M. Bassiouni, International Extradition and World Public Order 6 (1974). This same writer explained that such treaties further the purpose of international law, which is "designed to protect the sovereignty and territorial integrity of states, and [to] restrict impermissible state conduct. 1 M. Bassiouni, International Extradition: United States Law and Practice, ch. 5, 2, p. 194 (2d rev. ed. 1987).
The object of reducing conflict by promoting cooperation explains why extradition treaties do not prohibit informal consensual delivery of fugitives, but why they do prohibit state-sponsored abductions. See Restatement (Third) of Foreign Relations (Restatement) 432, and Comments a-c (1987).
[ Footnote 5 ] Treaty, 31 U.S.T., at 5062, 5063 (Articles 2 and 4).
[ Footnote 6 ] Id., at 5063, 5064-5065, 5066-5068, 5069 (Articles 3, 7, 10, 12, and 13).
[ Footnote 7 ] Id., at 5063-5064, 5065 (Articles 5 and 8).
[ Footnote 8 ] Id., at 5073-5074, 5062.
[ Footnote 9 ] Id., at 5065.
[ Footnote 10 ] The Court resorts to the same method of analysis as did the dissent in United States v. Rauscher, 119 U.S. 407 (1886). Chief Justice Waite would only recognize an explicit provision, and in the absence of one, he concluded that the treaty did not require that a person be tried only for the offense for which he had been extradited: "The treaty requires a delivery up to justice, on demand, of those accused of certain crimes, but says nothing about what shall be done with them after the delivery has been made. It might have provided that they should not be tried for any other offences than those for which they were surrendered, but it has not." Id., at 434. That approach was rejected by the Court in Rauscher and should also be rejected by the Court here.
[ Footnote 11 ] To make the point more starkly, the Court has, in effect, written into Article 9 a new provision, which says: "Notwithstanding paragraphs 1 and 2 of this Article, either Contracting Party can, without the consent of the other, abduct nationals from the territory of one Party to be tried in the territory of the other."
[ Footnote 12 ] It is ironic that the United States has attempted to justify its unilateral action based on the kidnaping, torture, and murder of a federal agent by authorizing the kidnaping of respondent, for which the American law enforcement agents who participated have now been charged by Mexico. See App. to Mexican Amicus 5a. This goes to my earlier point, see n. 4, supra, that extradition treaties promote harmonious relations by providing for the orderly surrender of a person by one state to another, and without such treaties, resort to force often followed.
[ Footnote 13 ] This Court has previously described a treaty as generally "in its nature a contract between two nations," Foster v. Neilson, 2 Pet. 253, 314 (1829); see Rauscher, 119 U.S., at 418 ; it is also, in this country, the law of the land. 2 Pet., at 314; 119 U.S., at 418 -419.
[ Footnote 14 ] Mexico's understanding is that "[t]he extradition treaty governs comprehensively the delivery of all persons for trial in the requesting state "for an offense committed outside the territory of the requesting Party." Brief for United Mexican States as Amicus Curiae, O.T. 1991, No. 91670, p. 6. And Canada, with whom the United States also shares a large border and with whom the United States also has an extradition treaty, understands the treaty to be "the exclusive means for a requesting government to obtain . . . a removal" of a person from its territory, unless a nation otherwise gives its consent. Brief for Government of Canada as Amicus Curiae 4.
[ Footnote 15 ] The United States has offered no evidence from the negotiating record, ratification process, or later communications with Mexico to support the suggestion that a different understanding with Mexico was reached. See Bassiouni, International Extradition: United States Law and Practice, ch. 2, 4.3, at 82 ("Negotiations, preparatory works, and diplomatic correspondence are an integral part of th[e] surrounding circumstances, and [are] often relied on by courts in ascertaining the intentions of the parties") (footnote omitted).
[ Footnote 16 ] Article X of the Treaty provided:
[ Footnote 17 ] The doctrine defined by the Court in Rauscher - that a person can be tried only for the crime for which he had been extradited - has come to be known as the "doctrine of specialty."
[ Footnote 18 ] In its opinion, the Court suggests that the result in Rauscher was dictated by the fact that two federal statutes had imposed the doctrine of specialty upon extradition treaties. Ante, at 4. The two cited statutes, however, do not contain any language purporting to limit the jurisdiction of the court; rather, they merely provide for protection of the accused pending trial.
[ Footnote 19 ] In fact, both parties noted in their respective briefs several authorities that had held that a person could be tried for an offense other than the one for which he had been extradited. See Brief for United States in United States v. Rauscher, O. T. 1885, No. 1249, pp. 6-10 (citing United States v. Caldwell, 8 Blatchford 131 (SDNY 1871); United States v. Lawrence, 13 Blatchford 295 (SDNY 1876); Adriance v. LaFave, 59 N. Y. 110 (1874)); Brief for Respondent in United States v. Rauscher, O. T. 1885, No. 1249, pp. 8-16.
[ Footnote 20 ] This principle is embodied in Article 17 of the Charter of the Organization of American States, Apr. 30, 1948, 2 U.S. T. 2394, T. I. A. S. No. 2361, as amended by the Protocol of Buenos Aires, Feb. 27, 1967, 21 U.S. T. 607, T. I. A. S. No. 6847, as well as numerous provisions of the United Nations Charter, June 26, 1945, 59 Stat. 1031, T. S. No. 993 (to which both the [504 U.S. 655, 679] United States and Mexico are signatories). See generally Mann, Reflections on the Prosecution of Persons Abducted in Breach of International Law, in International Law at a Time of Perplexity 407 (Y. Dinstein & M. Tabory eds. 1989).
[ Footnote 21 ] When Abraham Sofaer, Legal Adviser of the State Department, was questioned at a congressional hearing, he resisted the notion that such seizures were acceptable: "`Can you imagine us going into Paris and seizing some person we regard as a terrorist . . . ? [H]ow would we feel if some foreign nation - let us take the United Kingdom - came over here and seized some terrorist suspect in New York City, or Boston, or Philadelphia, . . . because we refused through the normal channels of international, legal communications, to extradite that individual?'" Bill To Authorize Prosecution of Terrorists and Others Who Attack U.S. Government Employees and Citizens Abroad: Hearing before the Subcommittee on Security and Terrorism of the Senate Committee on the Judiciary, 99th Cong., 1st Sess., 63 (1985).
[ Footnote 22 ] Justice Story's opinion continued:
[ Footnote 23 ] See Restatement 432, Comment c ("If the unauthorized action includes abduction of a person, the state from which the person was abducted may demand return of the person, and international law requires that he be returned").
[ Footnote 24 ] Henkin, A Decent Respect to the Opinions of Mankind, 25 John Marshall L. Rev. 215, 231 (1992) (footnote omitted).
[ Footnote 25 ] Thus, the Restatement states in part:
[ Footnote 26 ] Just as Rauscher had standing to raise the treaty violation issue, respondent may raise a comparable issue in this case. Certainly, if an individual who is not a party to an agreement between the United States and another country is permitted to assert the rights of that country in our courts, as is true in the specialty cases, then the same rule must apply to [504 U.S. 655, 682] the individual who has been a victim of this country's breach of an extradition treaty and who wishes to assert the rights of that country in our courts after that country has already registered its protest.
[ Footnote 27 ] In the international legal order, treaties are concluded by states against a background of customary international law. Norms of customary international law specify the circumstances in which the failure of one party to fulfill its treaty obligations will permit the other to rescind the treaty, retaliate, or take other steps. Vazquez, Treaty-Based Rights and Remedies of Individuals, 92 Colum.L.Rev. 1082, 1157 (1992).
[ Footnote 28 ] The treaty provided that the boarding rights could not be exercised at a greater distance from the coast than the vessel could traverse in one hour, and the seized vessel's speed did not exceed 10 miles an hour. Cook v. United States, 288 U.S., at 107 , 110.
[ Footnote 29 ] As the Illinois Supreme Court described the action:
[ Footnote 30 ] The Martinez incident discussed by the Court, see ante, at 665, n. 11, also involved an abduction by a private party; the reference to the Ker precedent was therefore appropriate in that case. On the other hand, the letter written by Secretary of State Blaine to the Governor of Texas in 1881 unequivocally disapproved of abductions by either party to an extradition treaty. In 1984, Secretary of State Schultz expressed the same opinion about an authorized kidnaping of a Canadian national. He remarked that, in view of the extradition treaty between the United States and Canada, it was understandable that Canada was "outraged" by the kidnaping and considered it to be "a violation of the treaty and of international law, as well as an affront to its sovereignty." See Leich, Contemporary Practice of the United States Relating to International Law, 78 Am.J. Int'l L. 200, 208 (1984).
[ Footnote 31 ] Article 16 of the draft provides:

[ Footnote 33 ] As Justice Brandeis so wisely urged:
[ Footnote 34 ] Certainly, the Executive's view has changed over time. At one point, the Office of Legal Counsel advised the administration that such seizures were contrary to international law because they compromised the territorial integrity of the other nation and were only to be undertaken with the consent of that nation. 4B Op.Off. Legal Counsel 549, 556 (1980). More recently, that opinion was revised, and the new opinion concluded that the President did have the authority to override customary international law. Hearing before the Subcommittee on Civil and Constitutional Rights of the House Committee on the Judiciary, 101st Cong., 1st Sess., 4-5 (1989) (statement of William P. Barr, Assistant Attorney General, Office of Legal Counsel, U.S. Department of Justice).
[ Footnote 35 ] Cf. Perkins v. Elg, 307 U.S. 325 (1939) (construing treaty in accordance with historical construction and refusing to defer to change in Executive policy); Johnson v. Browne, 205 U.S. 309 (1907) (rejecting Executive's interpretation).
[ Footnote 36 ] The South African court agreed with appellant that an abduction represents a violation of the applicable rules of international law, that these rules are part of [South African] law, and that this violation of the law deprives the Court . . . of its competence to hear [appellant's] case. . . . S. Afr. L. Rep., at 8-9.
[ Footnote 37 ] As Judge Mansfield presciently observed in a case not unlike the one before us today: "Society is the ultimate loser when, in order to convict the guilty, it uses methods that lead to decreased respect for the law." United States v. Toscanino, 500 F.2d 267, 274 (CA2 1974).
