We consider whether an administrative warrant issued pursuant to 18 U.S.C. § 4213(a) for the retaking of an alleged parole violator is subject to the oath or affirmation requirement of the Fourth Amendment’s Warrant Clause. We hold it is not and therefore affirm the denial of petitioner’s habeas challenge to his detention on an unsworn parole violator warrant.
I
Petitioner Brent Sherman is a federal inmate currently being held by the Bureau of Prisons at the Federal Detention Center in Sheridan, Oregon. In 1982, he was sentenced to twenty-years imprisonment for two counts of bank robbery and one year for failure to appear. In 1985, he escaped and committed armed robbery of another bank, crimes for which he received five years and twenty years, respectively. Because his offenses were committed prior to November 1, 1987, the effective date of the Sentencing Reform Act of 1984 which replaced most forms of “parole” with “supervised release,” Sherman received “old
*871
law” sentences under the former statutory-regime, which remains in effect as to such offenders.
See United States v. Kincade,
Paroled for the first time in 1993, Sherman’s parole was revoked two years later for possession of a controlled substance, extortion, and unlawful use of a weapon. He was paroled again in August 1999 and five years later requested a hearing for early termination under 18 U.S.C. § 4211(c)(1).
See Benny,
In November 2004, the Commission issued a parole violator warrant for Sherman’s retaking pursuant to 18 U.S.C. § 4213(a)(2) on the basis of two alleged parole violations: sexual assault (rape) in 2000, and fraud in 2000 and 2002. It is undisputed that the warrant application containing the allegations was unsworn. In December 2004, the U.S. Marshals Service took Sherman into custody on the warrant, and the following month he filed the underlying habeas petition under 28 U.S.C. § 2241 challenging his detention on the ground that the warrant was invalid under the Fourth Amendment because it was not supported by oath or affirmation.
While his habeas petition was pending, Sherman’s parole revocation proceedings continued before the Commission. After a preliminary interview, the interviewing officer recommended a finding of probable cause on the fraud charge, but not on the sexual assault charge. The Commission apparently took a somewhat different view. It found probable cause that Sherman had violated his parole, citing both charges, and continued to hold him pending a final hearing on revocation.
Meanwhile, in April 2005 the district court denied Sherman’s habeas .petition. In a published opinion,
Sherman v. Reilly,
Before the parties filed their briefs on appeal, however, the Commission revoked Sherman’s parole based on the fraud charge while making no findings concerning the sexual assault charge. He remains incarcerated with a presumptive re-parole date of October 13, 2007. The projected full-term date on his aggregate sentence is November 25, 2015.
II
The Government asserted below that Sherman’s habeas petition challenging his detention on the unsworn parole violator warrant became moot when the Commission conducted a preliminary hearing and found probable cause that Sherman violated his parole. It also asserted mootness in its brief on appeal, by. then predicating the argument on the Commission’s intervening revocation of Sherman’s parole. At oral argument, however, the Government conceded that this case is within the “capable of repetition, yet evading review” exception to the mootness doctrine. Undertaking our independent obligation to determine our subject-matter jurisdiction in the face of possible mootness,
see Dittman v. California,
The capable of repetition, yet evading review exception has been applied to permit appellate review of constitutional or statutory challenges to pretrial and other initial proceedings despite the regular progression of further proceedings making it “no longer possible to remedy the particular grievance giving rise to the litigation.”
United States v. Howard,
As in those contexts, a parolee’s initial detention solely on the authority of a parole violator warrant is by nature temporary and is “not likely to persist long enough to allow for the completion of appellate review” before the Commission either releases the parolee or takes further action providing superceding authority for the detention.
Woods,
This case is also capable of repetition. The Parole Commission has not retreated from its policy of issuing warrants based on unsworn allegations, and Sherman is scheduled for presumptive re-parole in October 2007 with over eight years remaining on his sentence. During that period of release, his liberty will continue to be conditioned on the Commission’s ability to issue a parole violator warrant and retake him based on unsworn allegations.
Cf. Woods,
For these reasons we agree with the parties that Sherman’s appeal from the denial of his habeas petition should not be dismissed as moot. We hold that despite the Parole Commission’s issuance of a revocation order providing superceding authority for Sherman’s present confinement, we have jurisdiction to review his initial *873 retaking and detention on a parole violator warrant under the exception for cases that are “capable of repetition, yet evading review.”

The Fourth Amendment rights of parolees are hardly uncharted waters. By now it is clear that parolees are protected against unreasonable searches and seizures.
Samson v. California, —
U.S. -,
Sherman’s habeas petition raises a closely related yet distinct question: When the United States Parole Commission issues a parole violator warrant pursuant to 18 U.S.C. § 4213(a) for the retaking of a federal parolee, must that warrant comply with the Warrant Clause of the Fourth Amendment and therefore be “supported by Oath or affirmation”? Because the question has both statutory and constitutional dimensions, we consider first whether Congress incorporated the Fourth Amendment definition of a “warrant” into § 4213 before addressing whether compliance with the Warrant Clause is otherwise constitutionally required.
A
Although we have interpreted 18 U.S.C. § 4213(a) in other contexts,
e.g., Benny v. U.S. Parole Comm’n,
(a) If any parolee is alleged to have violated his parole, the Commission may—
(1) summon such parolee to appear at a. hearing conducted pursuant to section 4214;' or
(2) issue a warrant and retake the parolee as provided in this section.
(b) Any summons or warrant issued under this section shall be issued by the Commission as soon as practicable after discovery of the alleged violation, except when delay is deemed necessary....
(c) Any summons or warrant issued pursuant to this section shall provide the parolee with written notice of—
(1) the conditions of parole he is alleged to have violated, as provided under section 4209;
(2) his rights under this chapter; and
(3) the possible action which may be taken by the Commission.
(d) Any officer of any Federal penal or correctional institution, or any Federal officer authorized to serve criminal process within the United States, to whom a warrant, issued under this section is delivered, shall execute such warrant by taking such parolee and returning him to the custody of the regional commissioner, or to the custody of the Attorney General, if the Commission shall so direct.
18 U.S.C. § 4213 (italics added).
On its face, despite setting forth several requirements for the issuance of a parole *874 violator warrant, § 4213 makes no mention of an oath or affirmation requirement. Instead, subsection (a) expressly authorizes the Commission to issue a warrant upon a mere allegation of a parole violation. The statute’s only other express requirements regard the issuer (“the Commission”), the timing (“as soon as practicable after discovery of the alleged violation”), and the contents of the warrant (“written notice” of the alleged violation, the parolee’s rights, and possible consequences). Id. § 4213(a)-(c). The implementing regulation is in accord, adding only that “satisfactory evidence” of the alleged violation is required. 28 C.F.R. § 2.44(a).
Nevertheless, Sherman contends that we should read the lone term “warrant” as implicitly incorporating the • Fourth Amendment definition. For this argument he relies on
United States v. Vargas-Amaya,
While we do not necessarily disagree with either premise, the issue is not so simple. Considering isolated terms without regard to the complete statutory language can be misleading, as can narrowly focusing on the holding of our opinions without due regard to the intricacies of our reasoning. Certainly Vargas-Amaya is a highly relevant precedent here given obvious similarities between the issues presented. But closer examination of that opinion reveals a textual analysis of the supervised release statutes that, when applied to the distinct language of the parole statutes, leads to precisely the opposite result.
1
In Vargas-Amaya we addressed whether the district court lacked jurisdiction under § 3583(i) to revoke supervised release after the release term had expired because the warrant on which the defendant was arrested was not supported by oath or affirmation. That statute provides:
The power of the court to revoke a term of supervised release for violation of a condition of supervised release, and to order the defendant to serve a term of imprisonment and ... a further term of supervised release,- extends beyond the expiration of the term of supervised release ... if, before its expiration, a warrant or summons has been issued on the basis of an allegation of such a violation.
18 U.S.C. § 3583(i) (italics added). Focusing narrowly on the word “warrant,” we invoked two canons of statutory construction: “in the absence of a statutory definition, a term should be accorded its ordinary meaning”; and “when Congress uses a term of art, such as ‘warrant,’ unless Congress affirmatively indicates otherwise, we presume Congress intended to incorporate the common definition of that term.”
Vargas-Amaya,
*875
But that is only the tip of the iceberg. As we also noted, these canons of statutory construction may be overcome if “Congress affirmatively indicates otherwise” or gives “ ‘contrary direction.’ ”
Vargas-Amaya,
Perhaps most remarkable about our analysis is that, despite initially applying the aforementioned presumptions regarding the implied meaning of the term “warrant,” we went on to determine that § 3583(1) “does not relate to the requirements for issuing a warrant at all.”
Vargas-Amaya,
Congress’ use of the past tense [in § 3583© ] stands in contrast to the Fourth Amendment, and Rules 4, 9, and 41 of the. Federal Rules of Criminal Procedure all of which discuss the requirements for issuing an arrest warrant in the present tense. See U.S. Const, amend, iy (“no Warrants shall issue”); Fed.R.Crim.P. 4(a) (“the judge must issue an arrest warrant”); Fed.R.Crim.P. 9(a) (“The court must issue a warrant”); Fed.R.Crim.P. 41(d) (“a magistrate judge or a judge ... must issue the warrant if there is probable cause”). The use of the past tense in § 3583© implies that' the statute does not relate to the requirements for issuing a warrant at all, but rather solely pertains to the court’s jurisdiction if an arrest warrant has already been validly issued. Another statute describes in the present tense when an arrest warrant may be issued for a violation of supervised release and provides that “If there is probable cause to believe that a ... person on supervised release has violated a condition of his ... release, ... the cburt ... may issue a warrant for the arrest of a ... releasee for violation of a condition of release.” 18 U.S.C. § 3606.
Id.
at 906;
accord United States v. Garcia-Avalino,
*876 • Of course, despite our determination that § 3583(i) itself is not controlling regarding the meaning of the term “warrant,” § 3606 confirmed the presumption that Congress intended to incorporate the Fourth Amendment definition. Reasoning that §§ 3583(i) and 3606 must be read consistently regarding the definition of a supervised release “warrant” and noting that § 3606 includes an express “probable cause” requirement, we concluded:
The only reasonable inference is that Congress was aware of the Fourth Amendment and incorporated its requirement that a warrant be based “upon probable cause” in both statutes. By extension, if Congress intended to incorporate the “probable cause” portion of the Warrant Clause in each statute, it must have also intended to incorporate the “Oath or affirmation” portion of the Clause.
Vargas-Amaya,
2
The plain language of § 4213 may seem superficially similar to the supervised release statutes we considered in Vargas-Amaya, but on closer inspection it is structurally and substantively distinct and not amenable to the same inferences. We therefore cannot reach the same conclusion that Congress intended to incorporate the requirements of the Warrant Clause of the Fourth Amendment.
To begin, by our reasoning in Vargas-Amaya, § 4213’s plain language makes it comparable not with § 3583(i) but with § 3606 insofar as the statute itself prescribes the requirements for issuing a valid warrant. Congress’ use of the present tense throughout § 4213(a)-(c) (“the Commission may ... issue a warrant,” “Any ... warrant ... shall be issued,” and “Any ... warrant ... shall provide”) stands in stark contrast to the past tense construction of § 3583(i) and instead parallels the present tense construction of § 3606 and Federal Rules of Criminal Procedure 4(a), 9(a), and 41(d).
But that is also where any parallels end. Read in context, Congress did not,use the term “warrant” in the same sense in both regimes. Section 4213 expressly authorizes only “the Commission” to issue a parole violator “warrant” and thereby provides for an
administrative warrant.
18 U.S.C. § 4213(a). Only in replacing parole with supervised release did Congress shift issuing authority to “the court” and thereby use the term “warrant” in the ordinary sense of a judicial warrant. 18 U.S.C. § 3606;
see Gozlon-Peretz v. United States,
Moreover, in § 4213 Congress omitted any express reference to the Warrant Clause’s requirements in describing the *877 issuance of a parole violator warrant. By contrast, § 3606 and Rules 4, 9, and 41 all expressly require “probable cause” for the issuance of an arrest warrant. See 18 U.S.C. § 3606 (“probable cause to believe that a probationer or a person on supervised release has violated a condition of his probation or release”); Fed.R.Crim.P. 4(a) (“probable cause to believe that an offense has been committed”); Fed.R.Crim.P. 9(a) (“probable cause that an offense has been committed”); Fed.R.Crim.P. 41(d)(1) (“probable cause to search for and seize $ person or property”). Additionally, Rules 4, 9, and 41 also contain clear references to a sworn facts requirement. See Fed. R.Crim.P. 4(a) (referencing “the complaint or one or more affidavits filed with the complaint”); Fed.R.Crim.P. 9(a) (“one or more affidavits accompanying the information”); Fed.R.Crim.P. 41(d) (“an affidavit or other information,” which may consist of “sworn testimony”).
The unique omission of any such references to the Warrant Clause in § 4213 is significant. In
Vargas-Amaya
we interpreted the express “probable cause” requirement within § 3606 as an implicit incorporation of the full Warrant Clause, which we then imputed to § 3583(i).
The natural reading of § 4213 is that the Commission is authorized to issue a parole violator warrant “[i]f any parolee is alleged to have violated his parole”-period. 18 U.S.C. § 4213(a). Although in Vargas-Amaya we determined that § 3583(i)’s “allegation” clause was largely irrelevant because of the statute’s past-tense construction, the converse is true here. Indeed, we expressly noted in Vargas-Amaya that if Congress 'were to use the present tense in conjunction with an allegation clause, that would indicate its intent to require only an allegation of a parole violation rather than full satisfaction of the Fourth Amendment:
The government argues that Congress specifically defined warrant as something less than that required by the Fourth Amendment — and, thus, that a warrant based on unsworn facts is acceptable — because of the phrase “on the basis of an allegation of’ a violation of supervised release. • 18 U.S.C. § 3583(i).... To effect its reading of the statute, the government asks us to rewrite § 3583© to mean that “a warrant or summons [may be] issued on the basis of an allegation of such a violation.” However, we are not at liberty to rewrite the words chosen by Congress.
Vargas-Amaya,

Contrary to our suggestion in
Vargas-Amaya,
Pending a determination of deportability in the case of any alien ..., such alien may, upon warrant of the Attorney , General, be arrested and taken into custody. Any such alien taken into custody may, in the discretion of the Attorney General and pending such final determination of deportability, (1) be continued in custody; or (2) be released under bond in the amount of not less than $500 with security approved by the Attorney General, containing such conditions as the Attorney General may prescribe; or (3) be released On conditional parole. But such bond or parole .... may be revoked at any time by the Attorney General, in his discretion, and the alien may be returned to custody under the warrant which initiated the proceedings against him and detained until final determination of his deportability ....
8 U.S.C. § 1252(a) (1976) (emphasis added); Immigration and Nationality Act of 1952, Pub.L. No. 82^14, § 242(a), 66 Stat. 163, 208-09 (1952). Indeed, deportation statutes going back to 1798 “have ordinarily authorized the arrest of deportable aliens by order of an executive official,” evidencing an “overwhelming historical legislative recognition of the propriety of administrative arrest for deportable aliens.”
Abel,
The same can be said of administrative arrests .of pabole violators, which Congress has authorized on the warrant of an executive official without requiring compliance with the Fourth Amendment’s Warrant Clause since the inception of federal parole in 1910. Parolees are legislatively “assigned to a unique status in our legal system.”
United States v. Potito,
If the warden of the prison or penitentiary from which said prisoner was paroled or the Board of Parole or any member thereof shall have reliable information that the prisoner has violated his parole, then said warden, at any time within the term or terms of the prisoner’s sentence, may issue his warrant to any officer hereinafter authorized to execute the same for the retaking of such prisoner.
18 U.S,C. ,§ 717 (1946);, Act of June 25, 1910, ch. 387, § 4, 36 Stat. 820 (original enactment); Act of May 13, 1930, ch. 255, § 1, 46 Stat. 272 (amendment).
Courts interpreting this legislation soundly rejected attempts by parole violators to claim certain rights enjoyed by ordinary citizens. In 1923, the Supreme Court characterized the nature of parole
*879
by stating that “[wjhile this is an amelioration of punishment, it is in legal effect imprisonment” and that a parole violator’s “status and rights were analogous to those of an escaped convict.”
Anderson v. Corrall,
If, contrary to this interpretation, Congress had actually intended to incorporate the Warrant Clause’s requirements, it could have expressed that intent in subsequent legislation. But despite recodifying the parole statutes in 1948, Congress made no such changes. Like the 1910 Act,- the 1948 Act continued to provide that a “parolee shall ... remain, while on parole, in the legal custody and under the control of the Attorney General,” and that “[a] warrant for the retaking of any United States prisoner who has violated his parole, may be issued only by the Board of Parole or a member thereof’ and shall be executed “by taking such prisoner and returning him to the custody of the Attorney General.” Act of June 25, 1948, ch. 645, 62 Stat. 854-55 (codified at 18 U.S.C. §§ 4203, 4205 and 4206, respectively). Even such a conspicuous change as the omission of the “reliable information” clause .from former § 717 was later dismissed by at least one court as “probably a drafting oversight” given the lack of any “express reference of congressional intent that would indicate that the change was intentional.”
Hyser v. Reed,
Given this legislative consistency, courts applying the 1948 Act maintained the view that Congress did not intend parole violator warrants to be within the scope of the Fourth Amendment', even despite growing recognition that parolees had some procedural due process rights in revocation proceedings. For instance, in an apparent departure from the Supreme Court’s “escaped convict” analogy in
Anderson,
the D.C. Circuit observed in
Hyser
that “in providing for a warrant type of procedure for retaking parolees thought to have violated parole conditions, Congress has recognized the need for some minimal procedural safeguards,” and that “something more than casual processes or varying improvisations ■ was intended.”
Id.
at 242, 244. Yet the court still stopped short of requiring compliance with the Fourth Amendment. Characterizing a parole violator warrant as an “administrative arrest warrant,” the court observed that “Congress evinced no intent to require precisely the same formalities and safeguards as to those contained in the Constitution for criminal arrests,” and it reaffirmed the view that “Congress meant to provide ... [that] the retaking [of a parole violator] is not ‘an arrest within the meaning of the constitutional provisions.’ ”
Id.
at 241, 244 (quoting
Story,
Even when Congress finally did respond to court decisions by codifying certain judicially-recognized due process rights of parolees, it again made no changes to bring parole violator warrants within the scope of the Fourth Amendment. The Parole Commission and Reorganization Act, Pub.L. No. 94-233, 90 Stat. 219 (1976), was Congress’ final recodification and comprehensive amendment to the parole statutes before the 1984 repeal, and it produced the provisions we construe today. It was intended in part to legislatively address the Supreme Court’s then-recent decision in
Morrissey v. Brewer,
Notably, however, neither the Supreme Court nor Congress suggested that stricter procedures were required for the issuance of a parole violator warrant for a parolee’s initial arrest. In
Morrissey,
despite tempering
Anderson’s
strong-form version of the “custody” theory, the Court nonetheless reaffirmed that “parole is an established variation on imprisonment of convicted criminals” and continued to give due recognition of that special status as limiting the rights of parolees as compared to ordinary citizens.
For our purposes, the 1976 Act is practically indistinguishable from the 1910 and 1948 Acts in authorizing the retaking of a parole violator on an administrative warrant outside the scope of the Fourth Amendment. Much like former 18 U.S.C. §§ 716 and 717 (1910-1948) and former 18 U.S.C. §§ 4203, 4205 and 4206 (1948-1976), the latest parole statutes continue to provide that “[a] parolee shall remain in the legal custody and under the control of the Attorney General,” and that “[i]f any parolee is alleged to have violated his parole, *881 the Commission may ... issue a warrant and retake the parolee” “by taking such parolee and returning him to the custody of the regional commissioner, or to the custody of the Attorney General.” 18 U.S.C.A. §§ 4210(a), 4213(a), (d) (West Supp.2007); Parole Commission & Reorganization Act § 2, 90 Stat.. at 226-28.
Although the 1976 Act did incorporate for the first time an express “probable cause” requirement for -revocation proceedings, it has no bearing on the issuance and execution of a parole violator warrant. The term appears not in § 4213 but in § 4214, which expressly applies only after a parolee has already been “summoned or retaken under section 4213.” 18 U.S.C.A. § 4214(a)(1)(A) (West Supp.2007);
see also
H.R.Rep. No. 94-838, at 34,
as reprinted in
1976 U.S.C.C.A.N. at 366 (“following the issuance of a summons or warrant”). While § 4214 entitles a retaken parolee to “a preliminary hearing ... to determine if there is probable cause to believe that he has violated a condition of his parole,” that inquiry is intended not as a post-hoc examination of the warrant’s validity but to determine whether the circumstances justify “incarceration of the parolee pending further revocation proceedings,” among other options. 18 U.S.C.A. § 4214(a)(1)(A) (West Supp.2007);
see also
S.Rep. No. 94-369, at 18,
as reprinted in
1976 U.S.C.C.A.N. at 339. Thus, the 1976 Act requires probable cause as a prerequisite only for continuing revocation proceedings beyond the preliminary hearing and extending a retaken parolee’s detention, not to compel an alleged parole violator’s appearance at such a hearing.
Cf. Gerstein v. Pugh,
Instead, for the first time Congress expressly referenced a mere allegation as the necessary predicate for issuing a parole violator warrant.
Compare
18 U.S.C. § 4213(a) (West Supp.2007) (“is alleged, to have violated his parole”)
with
18 U.S.C. § 4205 (1970) (“has violated his parole”)
and id.
§ 717 (1946) (“reliable information that the prisoner has violated his parole”). The legislative history also repeatedly mentions an allegation as a sufficient predicate.
See
S.Rep. No. 94-369, at 18,
as reprinted in
1976 U.S.C.C.A.N. at 339 (“In the case of allegations”); H.R.Rep. No. 94-838, at 33,
as reprinted in
1976 U.S.C.C.A.N. at 365-66 (describing § 4213 as “giving the Commission discretion to use either a summons or warrant when a condition of parole has alleged to have been violated”). Given the lack of any explanation of congressional intent regarding the allegation clause specifically, Congress might not have intended any substantive change from the prior Acts.

Finally, we are unpersuaded by Sherman’s argument that we should construe § 4213 as incorporating the requirements
*882
of the Warrant Clause in order to avoid raising serious doubts as to its constitutionality. Although in
Vargas-Amaya
we so applied the constitutional-doubt canon of statutory construction as to § 3583®, we did so only as an alternative rationale confirming our reading of the statute’s plain language. Because our textual analysis mooted any potential constitutional problems, we assumed
arguendo
that § 3583® was fairly susceptible of two constructions and then employed the canon of constitutional doubt to doubly reject the Government’s reading.
The canon of constitutional avoidance has no application when a statute’s language is unambiguous and Congress’ intent is clear. As our preceding textual analysis reveals, § 4213 is susceptible of only one construction, which we therefore, must adopt despite its potential for raising a significant constitutional question regarding the statute’s validity.
Almendarez-Torres v. United States,
Moreover, our interpretation of § 4213 as excepting administrative parole violator warrants from the Warrant Clause of the Fourth Amendment is entirely consistent with the presumption that Congress legislates in the light of constitutional limitations.
See Harris v. United States,
For all of the above reasons, we hold as a statutory matter that an administrative warrant issued by the Parole Commission *883 under 18 U.S.C. § 4213 for the retaking of an alleged parole violator need not be supported by oath or affirmation.
Thus, Sherman has failed to establish any deprivation of his statutory rights in support of his habeas petition.
B
We now turn to the constitutional question implicated by our statutory analysis. Pointing to the Fourth Amendment’s prohibition that- “no Warrants shall issue, but upon probable cause, supported by Oath or affirmation,” Sherman contends that sworn facts establishing probable cause are constitutionally required to support
all
warrants, even those issued by administrative agencies pursuant to statute. Consequently, he contends that his arrest and temporary detention on an un-sworn parole violator warrant issued by the Parole Commission pursuant to 18 U.S.C. § 4213 is inconsistent with the Warrant Clause and therefore unconstitutional.
Cf. Payton v. New York,
No doubt, the once prevailing view that searches and seizures of parolees present no Fourth Amendment issues has been rejected in our modern jurisprudence.
Latta v. Fitzharris,
By now it is clear that parole searches and seizures must “pass muster .under the Fourth Amendment test of reasonableness.”
Latta,
Parole is different, however. “[Rjevocation of parole is not part of a criminal prosecution and thus the full panoply of rights due a defendant in such a proceeding does not apply to parole revocations.”
Morrissey,
Accordingly, in the' parole context we have struck the proper balance between the individual and public interests by generally exempting parole searches and seizures from the requirements of the Warrant Clause. In
Latta
we held that the Fourth Amendment requires neither a warrant nor probable cause before a parole officer may search a California parolee.
These principles apply equally to federal parolees like Sherman. It is immaterial here that
Latta, Rabb
and
Butcher
all involved California state parolees or that California law may in some ways be stricter than federal law in terms of the conditions placed on parolees.
Compare
CaLPenal Code Ann. § 3067(a) (West 2007) (requiring that state parolees agree in writing to be subject to search or seizure at any time “with or without a search warrant and with or without cause”)
with
28 C.F.R. § 2.44 (West 2007) (requiring “satisfactory evidence” of a parole violation for the issuance of an administrative parole violator warrant). In
Latta
we con: sidered the Fourth Amendment rights of parolees without reference to such jurisdiction-specific provisions and instead relied on those characteristics of parole that are more
universal
— e.g., the nature, goals and purposes of parole, parolees’ unique legal status and diminished expectation of privacy, and the presence of long-standing statutory or judicial authority for warrant-less searchés and seizures of parolees.
Because searches and seizures of parolees are generally not subject to the requirements of the Warrant Clause, we conclude that the Fourth Amendment does not require an administrative parole violator warrant to be supported by oath or affirmation. We therefore hold that petitioner’s arrest on a unsworn parole violator warrant issued by the U.S. Parole Commission pursuant to 18 U.S.C. § 4213 was not unconstitutional under the Warrant Clause of the Fourth Amendment.
Lest there be any confusion, our holding today is in keeping with the fact that “[o]ur cases have not distinguished between parolees, probationers, and supervised releasees for Fourth Amendment purposes.”
Kincade,
IV
We hold that neither 18 U.S.C. § 4213 nor the Fourth Amendment require an oath or affirmation for the issuance of a valid administrative warrant for the retaking of an alleged parole violator. As petitioner alleges no other statutory or constitutional defect in the warrant on which he was retaken and held pending a preliminary hearing on revocation, we conclude his detention was not unlawful. The judgement of the district court denying Sherman’s habeas petition challenging his detention on an unsworn parole violator warrant is
AFFIRMED.
