*954 OPINION
Iwan Mandycz challenges the district court’s determination that he “illegally procured” his naturalization as an American citizen by failing to acknowledge his service as a prison guard in two concentration camps during World War II. See 8 U.S.C. § 1451(a). In bringing this challenge, he argues that the denaturalization order is not supported by the evidence, that the trial violated his due process rights, that laches barred the government from bringing this action and that the court erred in admitting certain evidence under the ancient-documents exception to the hearsay rule. We affirm.
I.
On January 23, 1920, Iwan Mandycz was born in Olievo-Korolivka, a small village located in what was then Poland, for a time was Nazi Germany, for a longer time was the Soviet Union and is now Ukraine. In the summer of 1941, as part of Operation Barbarossa, Nazi Germany took control of Poland and, with it, Olievo-Koroliv-ka.
As the war began to turn against Germany in 1942 and 1943, the country committed increasing numbers of troops to the eastern and western fronts, forcing it to recruit Eastern Europeans to fill positions vacated by the mobilized Germans. From February to April 1943, various SS units (“Schutzstaffel” or “protection squads,” JA 2073) recruited men from the Olievo-Koro-livka area to work as guards (Wachmcmn) at German concentration and forced-labor camps. Mandycz was one such recruit.
On April 7, 1943, Mandycz arrived by train at an SS training camp in Trawniki, Poland, where the Germans assigned him a unique identification number — 3308. All guards at Trawniki signed a declaration that they were “subject to the disciplinary code of ‘Police Troops’ and not to the jurisdiction of local or German civil courts.” JA 911 (expert testimony). All guards “received rifles and live ammunition.” JA 912. All guards “received service pay,” id., “free food, medical care, shelter and clothing,” JA 913. And all guards were eligible for “both an informal type of leave that might last an afternoon or for a single day, or more formally issued leave that would run anywhere from one week to three weeks.” JA 2021. The Germans did not treat the guards as part of the German army but as “part of the German police ap[p]aratus.” JA 2023.
Adjacent to the training camp was a forced-labor camp “in which the SS and police authorities incarcerated up to 6,000 Jewish prisoners and compelled them to work in war-related industries.” JA 886. As part of their training, the Trawniki enrollees guarded the camp.
A German transfer roster, dated May 25,1943, indicates that the Germans transferred Wachmann No. 3308, identified as “Iwan Manditseh,” to another Polish labor camp, Poniatowa. JA 985-86. On November 4, 1943, while Mandycz worked as a guard at Poniatowa, the Nazis massacred approximately 14,000 prisoners held at the labor camp. During the massacre, Traw-niki-trained guards cordoned off the camp while German SS troops forced Jewish men, women and children to stand in long, wide trenches, where the SS troops shot them with machine guns. The shooting lasted “all day long until the early evening,” JA 2105, after which the SS troops burned the victims’ bodies.
A second transfer roster indicates that on November 17,1943, the Germans transferred Wachmann No. 3308, identified as “Iwan Manntitseh,” from Poniatowa to Trawniki. JA 994-97. A third transfer roster created three days later indicates that the Germans reassigned Wachmann No. 3308, identified as “Iwan Mandytseh,” *955 from Trawniki to the “SS Death’s Head Guard Battalion, Sachsenhausen.” JA 1015-16. It is not clear “whether Guard 3308 actually reached Sachsenhausen,” D. Ct. Op. at 14, and his whereabouts from this point until the end of the war remain unclear.
In 1946, the United Nations established the International Refugee Organization to care for “the approximately 1,200,000 remaining World War II refugees in Europe.” JA 233;
see Fedorenko v. United States,
In 19,48, Mandycz sought to emigrate from Salzburg, Austria to the United States. To receive an immigrant visa under the Displaced Persons Act, he had to show that he was “the concern” of the International Refugee Organization. Displaced Persons Act of 1948, Pub.L. No. 80-774, § 2(b), 62 Stat. 1009 (defining a displaced person as “any displaced person or refugee ... who is the concern of the International Refugee Organization”). The Constitution of the International Refugee Organization excluded from .this category any person who could “be shown [ ] to have assisted the enemy in persecuting civil populations.”
Fedorenko,
The Commission in turn referred the case to ■ the Army Counterintelligence Corps, which interviewed Mandycz to determine whether he was “admissible into the United States under authority of the [Displaced Persons] Act of 1948.” JA 331. Mandycz informed the Corps that from 1943 to 1944 he had worked as a forced laborer for the “Seuring Company” in Vienna. JA 547, 970. He also produced a birth certificate dated July 23, 1920. The investigators did not have access to the records that would have implicated Man-dycz as a prison guard because “the three rosters identifying Iwan Mandycz as guard 3308 ... [were] held behind the Iron Curtain.” JA 2389. The Corps also did not receive “cooperation from local authorities or security agencies in countries under Soviet occupation, [such as Poland and Ukraine], so it was difficult ... to verify the background of applicants from these countries.” JA 486-87 (report of Mario DeCapua, head of investigations for the Commission after World War II). “In such cases, the [Corps and Commission] were forced to rely more heavily on full disclosure and honesty by the applicants.” Id. at 487. Relying on Mandycz’s representations, the Corps reported to the Commission that the “investigation disclosed no evidence that [the] Subject is or has been a member of, or a participant in, any movement which is or has been hostile to the United States.” JA 533.
On December 2, 1949, while still in Austria, Mandycz received his visa. He sailed from Bremerhaven, Germany, later that month, and on December 27, he entered the United States. On May 13, 1955, he applied for naturalization as a United States citizen with the Immigration and Naturalization Service; on June 30, the United States District Court for the Eastern District of Michigan granted his petition for naturalization. Mandycz settled in Detroit, where he has lived to this day. *956 Beginning in 1950 or so, he began working at Chrysler, first as a janitor and then as an auto worker, and remained employed there until his retirement from the company in 1983.
After the dissolution of the Soviet Union, the United States gained access to archives that implicated a number of postwar immigrants in assisting Nazi Germany. In March 1993, the Office of Special Investigations (OSI), a division of the Department of Justice that “detects and investigates individuals who took part in Nazi-sponsored acts of persecution abroad before and during World War II,” OSI website, available at http://www.usdoj.gov/ criminal/osi.html (last visited May 12, 2006), received materials from post-war Soviet interrogations indicating that an Iwan Mandyez had served as a guard at the Trawniki and Poniatowa camps. On September 17, 1996, after additional information implicated Mandyez in acts of persecution, OSI requested “a voluntary interview” with him to discuss the materials it had gathered. JA 82. Mandyez “declined to be interviewed.” Id. In March 1997, OSI attempted to confirm Mandycz’s birth date with Ukrainian authorities. After a couple of years (and some prodding by OSI), the Procurator General of Ukraine certified in August 1999 that Mandyez was born on January 23, 1920, exactly six months earlier than the birth date he had given during the immigration process.
On April 19, 2000, OSI filed a complaint in the Eastern District of Michigan under 8 U.S.C. § 1451(a) to revoke Mandycz’s citizenship, alleging that he had illegally procured it. At some point between 1996 and the filing of the complaint, Mandyez began to suffer from Alzheimer’s disease. On January 12, 2001, following an examination by OSI’s doctors, the court appointed a guardian under Rule 17(c) of the Federal Rules of Civil Procedure to represent Mandyez throughout the proceedings. After several pretrial proceedings (including a June 2002 appeal that this court dismissed as an impermissible interlocutory appeal,
see United States v. Mandycz,
H.
“The Constitution authorizes Congress to ‘establish a uniform Rule of Naturalization’ (Art. I, § 8, cl.4),” and naturalization remains “a privilege to be given or withheld on such conditions as Congress sees fit.”
Schneiderman v. United States,
In challenging the district court’s conclusion that Mandycz and Guard 3308 are one and the same, Mandycz makes one substantive argument and three procedural arguments: (1) the district court erred in finding he was Guard 3308; (2) the Due Process Clause prohibited the government from undertaking this denaturalization proceeding once it learned he was suffering from Alzheimer’s disease; (3) laches barred the government from bringing this denaturalization proceeding; and (4) the district court erred in admitting certain evidence. In resolving these disputes, we review the district court’s findings of fact for clear error, id. at 628, its conclusions of law for error, id. at 636, and its evidentia-ry rulings for abuse of discretion, id. at 633.
A.
Mandycz begins by contending that “OSI’s evidence did not meet the unusually high burden of proof required in denaturalization proceedings.” Mandycz Br. at 14 (capitalization removed). The government, it is true, faces a rigorous burden of proof in this setting.
Schneiderman,
The government’s proof rested on a collection of German guard-transfer rosters, which identified Mandycz as Guard 3308, and evidence- corroborating that identification.
First,
the three rosters identify Guard 3308 as having the same first name as Iwan Mandycz and as having a last name that phonetically matches Mandycz’s last name. The rosters variously describe Guard 3308 as “Iwan Manditsch,” JA 986, “Iwan Manntitsch,” JA 997, and “Iwan Mandytsch,” JA 1016. Each spelling of the last name, sure enough, does not match “Mandycz” letter for letter, but the differences are fairly explained. As the evidence showed, German clerks processing Eastern European guards repeatedly faced challenges in transliterating unfamiliar names. The name Mandycz was no exception: His last name ends with a sound that is rendered “sh” in English, “cz” in Polish, “ch” in Russian and “sch” in German. JA 880 (expert testimony). A similar problem plagued the clerks in trying to reduce the initial sound of the second syllable of Mandycz’s name to letters — with variations from “dy” to “di” to “ti.” JA 881 (expert testimony);
see also id.
(“As a result of [ ] haphazard transliteration decisions and general difficulties with foreign names, the German clerks spelled names inconsistently throughout their records.”). Because Guard 3308 had the same first name as Mandycz and the same phonetic last name as Mandycz, the transfer records support the district court’s decision.
See generally Grannis v. Ordean,
Second, in addition to matching Man-dycz’s first name exactly and his last name phonetically, the rosters identify his acknowledged place of birth and the only ascertainable date of birth for him. The third roster identifies “Iwan Mandytsch, 3308” as being “born on 23 January 1920 in Oliwa Koroliwka, Horodenka.” JA 1016. This birthplace matches Mandycz’s admitted birthplace and represents the birth date of the only Iwan Mandycz for whom the Ukrainian government has a record of birth in 1920. The parents listed on his Ukrainian birth certificate (“Dmytro Mandych” and “Mariya Skits’ko,” JA 1064) match the names admitted by Mandycz to be those of his parents (“Dmytro Man-dycz” and “Maria Skidzka,” JA 762). And the evidence supported the district court’s conclusion that no other Iwan Mandycz was born in Olievo-Korolivka in 1920. Mandycz, it is true, proffered a birth certificate dated “23 July 1920” in connection with his application for an immigration visa. JA 338. But forensic analysis revealed that the date on this birth certificate, exactly six months after the date listed on the Ukrainian-issued certificate and the transfer roster, could not be trusted because the authenticating stamp on the document had been “hand retouched.” JA 2441. This evidence led the forensic expert and the district court to determine that the birth certificate should “not be considered an authentic document” when it comes to the July 23 birth date listed there. JA 2452.
Third, the guard-identification numbers further eliminate the possibility that the transfer rosters identify someone other than the defendant. In each instance, the roster lists Mandycz’s name next to the same number — 3308. Expert testimony, credited by the district court, showed that these numbers were “specific to the individual guard and were never changed as long as he belonged to the Guard Forces of the SS.” JA 882. “Trawniki officials never ‘re-used’ or recycled the identification numbers of discharged men.” JA 910. Nor were these numbers “reassigned after a man left the Guard Forces or was killed.” JA 882. The repeated correlation of the same name (Mandycz) with the same number (3308), in combination with the biographical information listed on the third roster, provides compelling evidence that there was one and only one Iwan Mandycz who was born in Olievo-Koroliv-ka and who served as Guard 3308.
Fourth, still other evidence corroborates the information contained in the transfer rosters. Statements made by other Traw-niki guards during postwar Soviet interrogations identified Mandycz as a guard at Trawniki and Poniatowa and correctly remembered his birth date, birthplace, rank, nationality and itinerary. Trawniki-trained guard Stepan Perig remembered “Ivan Dmitrievich Mandych” and remembered that his “year of birth was 1920,” that his “place of birth is in O.-Korolivka,” that “[h]e enrolled in the SS police training camp in Travniki in April 1943,” that “[h]e underwent special training and guarded prisoners” and that “[h]e guarded prisoners in the camp of Ponyatovo.” JA 1082. Ivan Sidorak also remembered “Ivan Dmi-trievich Mandych” and remembered that his “year of birth [was] approximately 1920,” that “[h]is place of birth is in the village of Olievo Korolivka,” that “[h]e is Ukrainian by nationality,” that “[h]e was drafted with me to serve in the SS” and that “[h]e served as a Wachmann in the SS police training camp in Travniki from April 1943 until October 1943, after which *959 he was sent to the death camp in Ponyato-vo.” JA 1124.
Perig’s and Sidorak’s recollection of the middle name “Dmitrievich” further ties Mandyez to Guard 3308. As a patronymic, a name derived from one’s father, the middle name of “Dmitrievich” connects Man-dyez to his father, whose name (Mandyez concedes) is Dmytro.
Still another individual, Vasilij Gajdich, recalled that “Mandich and I arrived at the ‘SS’ police training camp at Travniki at the same time,” that “[h]e swore an oath and gave a commitment of voluntary service for the German punitive organs,” that “[h]e underwent a specialized course of training, after which he served as an '‘SS Wachmann’ and guarded prisoners” and that “[u]pon completing training, he and I were sent to the ‘SS’ camp in Ponyatovo.” JA 1243; see 473-74:
Fifth, Mandycz’s postwar relationship with Petro Perih, another guard at Traw-niki, corroborates the district court’s identification finding. During the postwar interrogations, Perig and Sidorak stated that Petro Perih had served at Trawniki. See JA 1102-03 (Périg: “[Perih] arrived at the SS training camp in Travniki with me.”); JA 1125 (Sidorak: “From April 1943, [Per-ih] served at the SS police training camp in Travniki. He performed the duties of an SS Wachmann”). They also gave similar estimates of P'erih’s date of birth (1922 or 1923) and remembered that he came from the same hometown (Olievo-Koroliv-ka). Perih’s Canadian immigration documents tie him to the Perih remembered by Perig and Sidorak, as they state that he was born in Olievo-Korolivka in 1924. After the war, Perih attended the wedding of Mandycz’s daughter. Mandycz’s telephone records also reveal that shortly before the government filed the complaint in this case, someone used his telephone to place three calls to Perih’s home. Man-dyez also listed Petro Perih during discovery in this case as' a person who would have “knowledge or information concerning your whereabouts, employment or activities in Europe between or including 1939 and 1945.” JA 792-93. As the district court permissibly found, Mandycz’s “post-war contacts with Petro Perih corroborate ' [Mandycz’s] identification with Guard 3308.” D. Ct. Op. at 26.
While considerable direct and corroborating evidence links Mandyez to Guard 3308, little evidence supports his contrary account of activities between 1943 and his arrival in this country. In one version of events, recounted in his October 1949 visa application, Mandyez claimed to work for a “Seuring Company” located in Vienna, Austria. JA 547. Yet neither Mandyez nor anyone else has produced any evidence showing that such a company existed. “[R]eseareh has not turned up any record that a firm by the name of ‘Seuring’ or ‘Seyring’ ever existed in Vienna,” JA 974 (expert testimony), and Mandyez stated in his 2001 deposition that he had never worked in Vienna and did not think that he had worked at Seuring.
In another version of events, recounted by Mandyez and confirmed by his daughter based on what Mandyez has told her throughout her life, Mandyez did not work in Vienna, but resided “in a camp in the Linz [Austria] area and was assigned out frequently to different farmers to work as an agricultural laborer.” JA 2126. Yet the account of Mandyez as a forced agricultural worker has no documentary support and conflicts with other evidence. See JA 976 (noting that no extant account “depicts living in a camp with- others and being picked up as needed by local farmers”); JA 977 (noting that “[a]gricultural laborers typically lived on the farms where they worked” because “German labor authorities realized significant cost savings by shifting the costs ... onto individual *960 farmers”); JA 2126 (“[F]orced laborers who were forced to reside in camps together were generally deployed at industrial concerns or in rural processing factories.”). Austria also created social-insurance records for forced laborers (in the event the laborer destroyed property of the employer), but the Austrian government’s “search[ ] for records verifying that Man-dycz served as a forced laborer during World War II .... produced no evidence that Iwan Mandycz resided as a forced laborer or was employed as a forced laborer in Austria ... between 1943 and 1945.” JA 2124. In the face of considerable evidence that Mandycz was Guard 3308 and in the absence of competing evidence that he was not, we credit the district court’s amply supported finding that that is who he was.
Trying to fend off this conclusion, Man-dycz points out that the government did not produce evidence that it has produced in similar denaturalization proceedings— namely, a Trawniki personnel file that would have contained Mandycz’s photograph and fingerprint as well as other biographical information. Doubtless, the district court (and we) would have preferred the record to contain this highly probative evidence. But just 1,200 out of 5,082 Trawniki guard files survived the war. So the absence of such a file does not prove that one never existed. The question rather is whether the evidence produced clearly and unequivocally showed that Mandycz was Guard 3308. The government’s evidence satisfied that burden, and other courts have credited similar forms and amounts of evidence in reaching similar conclusions.
See, e.g., United States v. Szehinskyj,
Mandycz also questions whether the district court should have relied on the Soviet interrogations, noting that they contain inconsistencies in his physical description. Perig described Mandycz as “tall, full build, blond hair,” JA 1103, while Gajdich described him as “tall in height, thin build, elongated face, brown-black hair,” JA 1243. The district court held that “[i]n light of the documentary and corroborating evidence, the variance[s] in physical descriptions of Iwan Mandycz provided in the interrogations are factually insignificant and unpersuasive.” D. Ct. Op. at 26.
Given the considerable documentary and corroborating evidence connecting Guard 3308’s name, birth date, birthplace and parents to Mandycz, these modest discrepancies' — occurring in two pieces of corroborative, otherwise consistent evidence and concerning shades of hair color and build' — do not undermine the district court’s identification finding. The statements were given in 1948, five years after these two individuals served with Mandycz over the course of a seven-month period from April 1943 to November 1943. “[Pjhysical descriptions,” as the record confirmed, “are often relative and often depend on the self-perception of the individual who is describing the person in question.” JA 1996. And even if the two men accurately recollected and assessed these physical features, no evidence shows that the two men perceived Mandycz at the same time. Summer of course may give brown hair a blond appearance, and it would hardly be unusual for guard service during a war to convert a full build into a thin one in a matter of months. In the end, these alleged discrepancies do not undermine the district court’s finding — as other courts have found in similar circumstances.
See, e.g., Hajda,
Mandycz, more generally, contends that the district court should not have credited the Soviet interrogation records, noting that in 1995 (in the district court’s words) “three men told Canadian authorities that Soviet investigators coerced or falsified confessions from them in the 1940’s.” D. Ct. Op. at 27. But in choosing not to credit these recantations, the district court observed that the three statements “contradict reliable historical evidence indicating that each [individual] participated in Nazi service” and that the three individuals made the statements to “avoid[ ] implicating themselves in atrocities and other bad acts.”
Id.
at 27. Under these circumstances, the district court did not abuse its discretion in declining categorically to reject the use of any and all Soviet interrogation records.
See, e.g., United States v. Kungys,
Nor, more specifically, has Mandycz shown that the interrogation records used in this instance were of dubious value. The three cited individuals have no connection to Mandycz, and the transfer records corroborate the interrogation records that the district court considered. On this record, we cannot say that the district court committed reversible error in considering these records.
B.
Mandycz next argues that the government violated his due process rights by bringing this denaturalization proceeding against him while he was mentally incompetent. The incompetence of any party to a denaturalization suit, he argues, operates as an absolute bar to the action, and even if that is not the case, the circumstances of his incompetency should have required the district court to halt this proceeding. We disagree.
In September 2000, OSI’s doctors examined Mandycz and determined that Alzheimer’s had taken a sufficient toll on him such that he was no longer of sound mind. Had the district court found that Mandycz was incompetent based on these examinations, that finding would have precluded the government from proceeding against him in a criminal proceeding. As the Supreme Court has “repeatedly and consistently recognized,” the criminal prosecution “of an incompetent defendant violates due process.”
Cooper v. Oklahoma,
*962
The problem is that “[a] denatural-ization suit is not a criminal proceeding,”
Schneiderman,
All of this remains true even when the case involves an incompetent party.
See Doe v. City of Lafayette, Ind.,
So while the commencement of a civil case does not suspend the Due Process Clause, it does alter the fairness requirements of the Clause. Whereas due process protects incompetent criminal defendants by imposing an outright prohibition on trial, it protects incompetent civil parties by requiring the court to appoint guardians to protect their interests and by judicially ensuring that the guardians protect those interests.
See
Fed.R.Civ.P. 17(c) (“The court shall appoint a guardian ad litem for an infant or incompetent person not otherwise represented in an action or shall make such other order as it deems proper for the protection of the infant or incompetent person.”);
see also Ferrelli v. River Manor Health Care Ctr.,
In Mandycz’s earlier appeal in this case, our court suggested a similar resolution of this issue. Soon after OSI’s doctors determined that he was incompetent, Mandycz filed an interlocutory appeal seeking to halt the denaturalization proceeding because it was sufficiently akin to a criminal proceeding. In denying leave to appeal, the court noted that “[denatural-ization proceedings are technically considered suits in equity, not criminal actions.”
United States v. Mandycz,
Perhaps appreciating this entrenched distinction between the civil and criminal due process protections for incompetent individuals, Mandycz has filed a supplemental brief indicating that he “is not arguing for due process protection for all ‘civil’ defendants” but only for protection for denaturalization defendants facing his unique circumstances. Mandycz Supp. Br. at 13;
see id.
(“Recognition of such a due process right is only reasonable in light of the extraordinarily unique posture of this case.”). While we need not decide today whether there could be a denaturalization proceeding in which due process requires more protection than this civil defendant received, Mandycz has not convinced us that his circumstances warrant an exception to the rule. In one sense, the district court exceeded the requirements of due process as it appointed a guardian for Mandycz without making a finding that he was incompetent; the court apparently determined that the examination results of OSI’s doctors sufficed to make the appointment of a guardian appropriate. Nor has anyone alleged that the guardian failed to look after Mandycz’s interests or that Mandycz otherwise failed to receive “a fair trial before an impartial decisionmaker.”
Kairys,
In another sense, the district court was presented with a party who, despite his illness, was able to offer considerable assistance to his defense, a feature of this case that will not invariably be replicated in other civil proceedings involving incompetent parties. Keep in mind that the government first notified Mandycz of its investigation in 1996 when it asked to interview him about whether he had been a guard at Nazi labor and concentration camps. And the government filed this complaint in 2000. Mandycz first complained about memory loss in 2000, and no one contends that he was unable to assist his defense in 1996 when he first learned about this inquiry. Indeed, the district court found that Mandycz exhibited “lucidity at his deposition” in May 2001, D. Ct. Op. at 34, as he “recounted that he was taken from his home to work on a farm in Linz during World War II,” a story that was “the same one [he] told his adult daughter throughout her life” and to which she was permitted to testify, id. at 33. He told this story in considerable detail, giving his attorneys ample opportunity to verify his claims and substantiate them with evidence — whether from immigration records, from his family or from acquaintances.
Mandycz, notably, has not challenged the district court’s finding that he exhibited “lucidity” at his deposition or the court’s finding that his daughter’s independent recollections corroborated his version of events. Compare JA 1510-11, 1518, 1631 (Mandycz) (agreeing that “in 1943 the Germans were recruiting young men in [Olievo-Korolivka],” and remembering that he was taken “[t]o Austria to work,” “to Linz in Austria,” and that after the war ended, he went “[t]o Salzburg”) with Donna Christina Depo. at 132-33 (daughter) (“He said Linz” was where he stayed; “I know he was at home, Olijewa Korliwka, and then he was in Linz. Then he went to Salzburg .... I think it was ’43 and *964 then ’45 the war was over.”); compare also JA 1519 (Mandycz) (“Trucks came and they were taking us somewhere to camps and we were told you’re going to live here. And from here you will be taken to farms.”) with Christina Depo. at 50-51 (daughter) (“[H]e worked on the farm during the summer” and stayed in “some kind of area where the workers lived .... ”). Even if we were to acknowledge the possibility of granting an exception to the traditional civil rules for denaturalization proceedings, Mandycz has not shown that this is an appropriate case for doing so.
Mandycz, finally, points out that “an incompetent person may not, as a matter of law, voluntarily renounce his or her citizenship.” Mandycz Br. at 27. That may be true but it does not help his claim. Under 8 U.S.C. § 1481(a)(5), “[a] person who is a national of the United States ... shall lose his nationality by voluntarily ... making a formal renunciation of nationality before a diplomatic or consular officer of the United States in a foreign state.” The statute thus requires renunciation to “be by voluntary act,”
Perri v. Dulles,
C.
Mandycz next argues that laches barred the government from bringing this denatu-ralization claim given the lapse of time between the government’s first discovery of evidence that Mandycz was a prison guard and the filing of this complaint. We disagree.
Because the United States acted in its sovereign capacity when it sought to denaturalize Mandycz, the common law doctrine of laches does not apply. “It is well settled that the United States is not ... subject to the defense of laches in enforcing its rights.”
United States v. Summerlin,
Whatever the scope of the exception to this rule — triggered when the government stands in the shoes of a private party, as opposed to when it acts in its sovereign capacity,
see Hatchett,
Costello v. United States,
But circuit precedent forecloses Man-dycz from threading this needle. In
United States v. Weintraub,
But even if we were to consider the defense, it would not aid Mandycz. The laches defense has “two elements: (1) unreasonable delay in asserting one’s rights; and (2) a resulting prejudice to the defending party.”
Brown-Graves Co. v. Cent. States, Se. & Sw. Areas Pension Fund,
*966 D.
Mandycz, lastly, challenges the authenticity of the Soviet interrogation records and their admissibility under the ancient-documents exception to the hearsay rule. Under that exception, courts may admit into evidence “[statements in a document in existence twenty years or more the authenticity of which is established.” Fed. R.Evid. 803(16). Authenticity in turn is a function of whether the document “(A) is in such condition as to create no suspicion concerning its authenticity, (B) was in a place where it, if authentic, would likely be, and (C) has been in existence 20 years or more at the time it is offered.” Fed. R.Evid. 901(b)(8).
Though conceding that the Soviet interrogation records are at least 20 years old, Mandycz claims that this hearsay exception does not apply because the documents are not “authentic.” In support of this argument, he marshals a variety of sources to make the point that the Soviet Union did not value
truth
— e.g., “To speak the truth is a petty bourgeois prejudice. To lie, on the other hand, is often justified by its ends,”. Vladimir Lenin
in
Chapman Pincher,
The Secret Offensive
24 (1985) — then reasons that all documents of the old regime “lack trustworthiness.” Mandycz Br. at 35. Putting to one side the sweeping breadth of his argument, it suffers from a more basic problem. “Although Rule 901(b)(8) requires that the document be free of suspicion, that suspicion goes not to the content of the document, but rather to whether the document is what it purports to be.”
Demjanjuk,
Hi * ❖ ^ * *
While Iwan Mandycz has only the prospect of review in the Supreme Court before this denaturalization proceeding comes to an end, that does not mean he has reached the end of the road when it comes to deportation. A denaturalization finding permits the Attorney General to seek deportation; it does not require him to do so. The government concedes as much,
see
Gov’t Supp. Br. at 1 (“[T]he Government
does
have prosecutorial discretion” “to refrain from removing incompetent persons .... ”), and acknowledges that it has exercised such discretion before.
See also Reno v. American-Arab Anti-Discrimination Comm.,
III.
For these reasons, we affirm.
