Perlie Donald Workman appeals from the district court’s order revoking his probation. We vacate the order and remand the case for further proceedings because revocation was based on evidence obtained by searches that violated the fourth amendment.
I
Workman was convicted in May of 1973 on his guilty pleas to two counts of an indictment charging possession of a distillery and bootleg whiskey. The court suspended his sentences aggregating five years and placed him on probation for five years. Two of the conditions of his probation were that he not possess, manufacture, sell, or buy any illegal whiskey and that he not violate any law of the United States or North Carolina.
In a complaint filed in February, 1977, a probation officer asked the court to revoke Workman’s probation for violation of these conditions. The complaint alleged that in the previous December, police officers destroyed an illegal distillery found in Workman’s home. The complaint also disclosed that in a state prosecution based on this incident, the North Carolina court ruled that the search of Workman’s residence was illegal because the warrant on which it was based did not comply with the fourth amendment. The state court suppressed the evidence and dismissed the case.
Two months later, the probation officer filed a second complaint alleging that *1207 Workman possessed an illegal distillery in a building located on his property. This complaint was based on evidence discovered during a warrantless search in April, 1977, by the probation officer and an Alcohol Beverage Control agent. The officer testified that he searched the storage shed because he had a report that Workman kept a still there. He said that he did not obtain a search warrant because he believed that he did not need one.
The district court ruled that a “federal probation officer in the performance of his duties may conduct reasonable searches of a probationer and his premises without a warrant when probable cause exists.” Consequently, it considered the evidence discovered during the officer’s April search. The court also held that the exclusionary rule does not apply to probation revocation proceedings. It therefore concluded that it could also consider the evidence concerning the December incident notwithstanding the state court’s determination that it had been illegally obtained. 1 Based on all the evidence, the court revoked Workman’s probation and imposed concurrent two-year sentences.

The first issue is whether a probation officer can conduct warrantless searches of his probationer’s premises whenever he has probable cause. Relying primarily on
United States v. Bradley,
In
Bradley
we held “that unless an established exception to the warrant requirement is applicable, a parole officer must secure a warrant prior to conducting a search of a parolee s place of residence even where, as a condition of parole, the parolee has consented to periodic and unannounced visits by the parole officer.”
We recognize the similarity between searches by probation officers and administrative searches by officials to enforce civil regulations. But as we made clear in
Bradley,
this analogy affords no reason for dispensing with a warrant. This conclusion has been buttressed by
Marshall v. Barlow’s, Inc.,
In
Martin v. United States,
*1208 There is no doubt that the Fourth Amendment protects all persons suspected or known to be offenders as well as the innocent, and it unquestionably extends not only to the persons but also to the houses of the people, whether they be residences or places of business. . The Amendment applies in this case to Martin, a probationer, and to his garage located near his home, although his status is a circumstance to be taken into consideration; but the question remains whether the search and seizure were unreasonable and therefore a violation of the right conferred upon him to be secured against such a search.
Consequently, in determining whether evidence seized by a probation officer without a warrant was admissible, the Martin court applied a traditional exception to the fourth amendment’s requirement of a warrant. It admitted the evidence because the probation officer acting on probable cause made the search as an incident to his lawful apprehension of the probationer. The court did not rest its opinion on the theory that a probation officer can search a probationer’s property without a warrant in the absence of exigent circumstances.
Congress has granted broad authority to probation officers, including the power to arrest without a warrant. 18 U.S.C. § 3653. Significantly, however, Congress has not authorized probation officers to conduct warrantless searches. This absence of legislative authority distinguishes probation officers from inspectors who are empowered by statute to conduct searches of certain regulated businesses without warrants.
Cf. United States
v.
Biswell,
The restriction on a probation officer’s authority to search does not preclude warrantless visits to the probationer’s home or place of employment. Inherent in the probation officer’s duty to “use all suitable methods ... to aid probationers and to bring about improvements in their conduct and condition”
3
is authority to visit the probationer. A visit, however, is not a search.
Cf. Wyman v. James,
Nor does the lack of authority to conduct a warrantless search prohibit a probation officer from acting as any other officer in exigent circumstances. Thus he may search and seize articles as an incident to a lawful arrest.
Martin v. United States,
Although probation officers have been accorded broad authority so they may effectively discharge their duties, Bradley and Martin establish that they must obtain search warrants in the absence of recognized exceptions to the requirements of the fourth amendment. We find in this case no occasion for departing from the precedent of those decisions.
Ill
The government next argues that even if Workman is entitled to the protection of the fourth amendment, the evidence obtained in an illegal search should nevertheless be admitted. In support, it relies on a number of cases which have not applied the exclusionary rule to proceedings involving probationers.

Application of this rule
*1209
excludes evidence seized in violation of the fourth amendment.
Mapp v. Ohio,
The preliminary question posed by this issue is whether a probationer has standing to invoke the exclusionary rule. Standing is restricted to the victim of a search against whom the government seeks to use evidence allegedly tainted by an unlawful search.
Alderman v. United States,
A more difficult problem is whether the nature of a probation revocation hearing requires an exception to the exclusionary rule. The answer lies in the application of the test prescribed by
United States v. Ca-landra,
A probation revocation hearing is adjudicative. Its first purpose is to determine whether the probationer is guilty of violating a provision of the probation order. Its second is to decide whether he should be continued on probation or be imprisoned. Although such a hearing is not a stage of a criminal prosecution, it is a criminal proceeding that may result in the loss of liberty.
5
For this reason the due process clause entitles a probationer to written notice of his alleged violation; a hearing at which the evidence against him must be disclosed; the right to present witnesses in his own behalf; and, save in exceptional circumstances, the right to confront and cross-examine adverse witnesses. If a serious ques
*1210
tion of culpability exists, the probationer is constitutionally entitled to the assistance of counsel. In 1970 Congress augmented the constitutional requirements by providing a statutory right to counsel at all federal revocation hearings.
See generally Gagnon v. Scarpelli,
Consideration of the nature of a probation revocation hearing leads to the conclusion that the application of the exclusionary rule will result in approximately the same potential for injury and benefit as its application in other criminal adjudicative proceedings. The rule’s exclusion of some of the evidence about the new charges which form the basis of the complaint about the probationer, the delay incident to suppression hearings, and the rule’s effectiveness in deterring future unconstitutional searches are neither significantly more nor less than in other such adjudicative proceedings. Therefore, the weight to be assigned the potential advantages and disadvantages of applying the rule to probation revocation proceedings cannot be ascertained by generalized reference to the pros and cons of the rule — a subject that has been the topic of lively debate from the moment of the rule’s promulgation. Instead, an inferior court should conduct the balancing test prescribed by
United States v. Calandra,
The Court has held the rule inapplicable to evidence introduced against a defendant who was not the victim of the search.
Alderman v. United States,
In refusing to exclude from a federal tax case evidence alleged to have been illegally seized by state officers, the Court noted, “In the complex and turbulent history of the rule, the Court never has applied it to exclude evidence from a civil proceeding, federal or state.”
United States v. Janis,
where the State has provided an opportunity for full and fair litigation of a Fourth Amendment claim, the Constitution does not require that a state prisoner be granted federal habeas corpus relief on the ground that evidence obtained in an unconstitutional search or seizure was introduced at his trial.
The Court has also ruled, as we have previously mentioned, that the exclusionary rule does not apply to a grand jury.
United States v. Calandra,
On the other hand, the Court has consistently applied the exclusionary rule to af
*1211
firmative proof offered by the government in state and federal criminal trials.
See Mapp
v.
Ohio,
As this brief survey discloses, the Supreme Court has never exempted from the operation of the exclusionary rule any adjudicative proceeding in which the government offers unconstitutionally seized evidence in direct support of a charge that may subject the victim of a search to imprisonment. Indeed, the Court has observed that standing to invoke the exclusionary rule “is premised on a recognition that the need for deterrence and hence the rationale for excluding the evidence are strongest where the Government’s unlawful conduct would result in imposition of a criminal sanction on the victim of the search.”
United States v. Calandra,
We conclude therefore that evidence obtained by unconstitutional searches of a probationer’s property is inadmissible in a federal probation revocation hearing. We do not, of course, determine whether Workman’s probation should be continued or revoked. That decision must be made by the district court without reliance on the unconstitutionally seized evidence.
The order of the district court is vacated, and the case is remanded for further proceedings consistent with this opinion. Upon remand, the district court should permit the government to amend its complaints if it be so advised.
Notes
. The district court decided the case on the assumption that the state court had ruled correctly, and for the purposes of this appeal we will accept this premise. On remand the government should not be foreclosed from asserting that the December search was legal if it cares to do so.
Elkins v. United States,
. Here, as in
Bradley,
the government relies primarily on
Latta v. Fitzharris,
. 18 U.S.C. § 3655.
.
See, e. g., Latta v. Fitzharris,
United States v. Vandemark,
. Probation is of statutory origin. Congress recognized that it has the characteristics of a criminal proceeding by including the statutes pertaining to it in Title 18 of the United States Code, “Crimes and Criminal Procedure,” 18 U.S.C. §§ 3651-56. Probation is also governed by Federal Rules of Criminal Procedure 32(e) and (f).
. 18 U.S.C. § 3653 provides that upon the conclusion of a hearing, “the court may revoke the probation and require him [the probationer] to serve the sentence imposed, or any lesser sentence, and, if imposition of sentence was suspended, may impose any sentence which might originally have been imposed.”
