Donald Edward Mozingo, a California state prisoner, petitioned the district court for a writ of habeas corpus. He complained that at a Parole and Community Service hearing, which resulted in the suspension of his parole for engaging in a bar room brawl, and in a subsequent parole revocation hearing on March 13, 1970, based on the same charge, he was denied the asserted due process right of confronting and cross-examining the witnesses who testified against him.

After a hearing the district court ordered that a writ issue unless, within sixty days, the warden and the State of California institute a new hearing on these charges before the California Adult Authority, 341 F.Supp. 296 . Such a hearing, the court ordered, must meet the requirements of due process, “including the right of the petitioner to the as sistance of counsel, to confront adverse witnesses and to present witnesses on his own behalf.” The warden appeals.

Appellant has moved for an order vacating the district court order as moot and dismissing the petition. In support of this motion appellant points out that, following the revocation of parole in question, Mozingo was once more re-, leased on parole, violated the terms of the latter parole, and is now in custody as a result of the revocation of the latter parole.

At oral argument we asked counsel for appellant to ascertain whether the California Adult Authority would agree to disregard the complained-of March 13, 1970, parole revocation in the future if this court ordered the district court to vacate its judgment and dismiss the petition as moot. Counsel has reported to us that he has been unable to obtain such an assurance.

Because of possible prejudice to Mozingo inherent in the questioned revocation of parole, notwithstanding the subsequent parole revocation not here in question, we deny the motion that the proceeding be terminated as moot. See Scarpelli v. Gagnon, 317 F.Supp. 72 (E.D.Wis.1970), aff’d, Gunsolus v. Gagnon, 454 F.2d 416, 418, 423 (7th Cir. 1971) , cert. granted, 408 U.S. 921 , 92 S.Ct. 2490 , 33 L.Ed.2d 331 (1972).

Having in view the previous state court proceedings in which Mozingo sought to set aside the parole revocation in issue, we also reject appellant’s contention that Mozingo has failed to exhaust his state remedies.

In entering the order under review, the district court relied primarily upon the decisions of this court in Wilburn v. Nelson, 458 F.2d 502 (9th Cir. 1972); and Dennis v. California Adult Authority, 456 F.2d 1240 (9th Cir. 1972). We agree with the district court that, under the circumstances of this case, the Wilburn and Dennis decisions call for a conditional grant of the writ such as was ordered in this case.

Because of the subsequent parole revocation proceedings referred to above, Mozingo is not entitled to release pending the reinstituted parole revocation proceedings provided for in the district court order.

Affirmed.

. Counsel for appellant cites three cases to support his contention that the challenge to the parole revocation of March 13, 1970, is moot. The most recent case, Nelson v. United States, 443 F.2d 75 (5th Cir. 1971), appears to support this proposition. However, the court in Nelson apparently did not consider the possible collateral consequences of the challenged parole revocation. If there were none, then Nelson is distinguishable from Mozingo. In Mozingo, each time parole was revoked the sentence was refixed for a longer term, thus collateral consequences continue even though he was paroled again and that parole was revoked. What we say of the Nelson case is also true of Blackburn v. United States Parole Board, 429 F.2d 364 (5th Cir. 1970). In Marchand v. Director, United States Probation Office, 421 F.2d 331, 336 (1st Cir. 1970), the court did recognize a distinction between the petitioner, who was no longer under the continuing jurisdiction of the parole board, and someone who was under that jurisdiction. Thus, Marchand is distinguishable from Mozingo because of the absence of collateral consequences in Marchand . . The basic constitutional requirements which must be satisfied as a matter of course in every parole revocation proceeding, as announced in Morrissey v. Brewer, 408 U.S. 471 , 92 S.Ct. 2593 , 33 L.Ed.2d 484 (1972), are applicable to revocations of parole entered after June 29, 1972, when Morrissey was decided (see 408 U.S. at 490 , 92 S.Ct. 2593 and are not applicable to Mozingo’s parole revocation of March 13, 1970. See M’Clary v. California Adult Authority, 466 F.2d 1122 (9th Cir. 1972). See also, People v. Vickers, 8 Cal.3d 451 , 105 Cal.Rptr. 305 , 503 P.2d 1313 (1972). However, prior to Morrissey , this court held that due process requires that parole boards employ such procedures, to be determined on a case-by-ease basis, as are “reasonably . and fairly designed to enable it to ascertain whether issues existed concerning the asserted violation and to make an informed decision upon such issues.” Dennis v. California Adult Authority, 456 F.2d 1240, 1241 (9th Cir. 1972). See also M’Clary, supra; Wilburn v. Nelson, 458 F.2d 502 (9th Cir. 1972). This rule of case-by-case determination, which was the basis for the conditional writ granted by the district court here, is not affected by the non-retroactivity of Morrissey .
