*685 OPINION OF THE COURT
This appeal from a denial qf a petition for a writ of habeas corpus requests this court to reconsider our decision in United States ex rel. Halprin v. Parker,
The weight of federal authority being in accord with our view, we are not disposed to modify
Halprin. See,
Ellhamer v. Wilson,
I
On April 11, 1963, Martinez was convicted of violating 21 U.S.C. §§ 173 and 174 (narcotics), and sentenced to ten years imprisonment. On February 14, 1969, he was granted a mandatory release on parole from the U. S. Penitentiary, Lewisburg, Pennsylvania, under the provisions of 18 U.S.C. §§ 4163 and 4164. After being arrested thereafter by New York State authorities on a charge of possession of cocaine, he entered a plea of guilty in the New York State courts and was sentenced to prison for eleven months.
On January 22, 1970, while Martinez was still in state custody, the U. S. Board of parole issued a mandatory release violator’s warrant for his arrest. One of the reasons for the issuance of the Parole Board warrant was Martinez’s arrest on the New York State narcotics charge. Upon his release from state custody on November 2, 1970, he was taken into federal custody on the Parole Board warrant. On December 1, 1970, he was afforded a preliminary interview by the U. S. Probation Office for the Southern District of New York. At that time he waived the right to a local revocation hearing, executed a waiver of counsel form, and admitted that he had violated one or more of the conditions of his release, to-wit, he admitted his arrest, plea, conviction and sentence on the New York narcotics charge.
Martinez now contends that these admissions were made only after his requests for counsel were refused and he had been informed that counsel would not be provided. Martinez claims that *686 these admissions would not have been made if he had been provided counsel. Putting aside the obvious — that the Board of Parole knew of the violation and could prove its existence without his admission because the Board had executed the arrest warrant while Martinez was in state custody serving state time for an offense committed while on federal parole, an offense which he admitted committing by his plea of guilty in New York — we now turn to appellant’s right of counsel contention. 2
Although neither at the hearing nor in these proceedings does appellant controvert that he indeed committed the state offense, and, in doing so, violated the terms of his federal parole, he nevertheless urges that the Sixth Amendment guaranteed the right to appointed counsel at his parole revocation hearing. He claims that the mandatory release revocation hearing is a critical stage in a criminal prosecution at which important rights may be lost.
Cf.,
Gideon v. Wainwright,
Relying on the due process clause, Martinez attacks the holding of
Halprin
as unsound, contending it is the progeny of Escoe v. Zerbst,
Appellant’s argument has superficial appeal. It is true that the district court’s memorandum opinion in
Halprin
was based upon the authority of Hyser v. Reed,
Moreover, even accepting that
Halprin
is founded upon the right-privilege dichotomy, as advanced by appellant, it does not necessarily follow that due process requires appointment of counsel for indigents at mandatory release revocation hearings. Addressing itself to the due process issue in Morrissey v. Brewer,
supra,
Procedural due process is not a scientifically exact concept to be applied rigidly and uniformly to a wide range of disparate situations. Rather the concept is flexible, and is translated into specific safeguards only after evaluating the nature of the governmental function involved and the private interest to be affected by governmental action. Caferia & Restaurant Workers Union v. McElroy,
II.
In evaluating the private and governmental interests to be balanced to determine the parameters and nature of due process required in a mandatory release revocation hearing, we limit ourselves to the situation presented by the facts of this case, viz., one in which the facts upon which revocation is predicated are uncontroverted. 3 Thus posited, the private and governmental interests do not *688 fit the classic mold of adversariness as, for example, the configuration of the prosecution and the accused in a criminal case. This type of hearing is not designed to reach findings to be ascertained from conflicting assertions of fact. The rules of evidence are not applicable to this informal hearing and, hence, do not present an obstacle to a mandatory releasee untrained in the law. No adversary representing the government is present, actively pursuing interests antagonistic to the interests of the mandatory releasee; rather the releasee is confronted by uncontroverted facts of a parole violation. Under such circumstances, this court and the other circuits hold that the releasee can adequately protect his interests without the necessity of counsel.
Having concluded that due process does not require appointment of counsel for an indigent releasee at a mandatory release revocation hearing at which no factual controversy exists, we adhere to our prior holding of Halprin and find no constitutional deprivation.
The judgment of the district court will be affirmed.
Notes
. The Tenth Circuit is in accord with our view where the facts of parole or mandatory release revocation are uncontroverted. Cotner v. United States,
As to whether counsel is required in a Wisconsin state revocation proceeding, see Goolsby v. Gagnon,
. Hei-e the facts of Martinez’s arrest, guilty plea and conviction, were .matters of public record, of which a court may take judicial notice.
