In November, 1976, appellant was convicted of five counts of an indictment charging him with violations of 21 U.S.C. §§ 846 and 841(a)(1) — conspiracy, manufacturing, possession and distribution of controlled substances, specifically, amphetamine and phencyclidine (PCP). After diagnostic study he was sentenced to a term of eight years pursuant to the provisions of 18 U.S.C. § 4205 (b)(2). A year later he applied for parole and was granted a hearing, following which parole was denied. He unsuccessfully sought relief through administrative appeals, and in August, 1978, filed a petition for habeas corpus attacking the refusal of the Commission to grant him parole. That petition was denied by the district court and this appeal was taken.

In 18 U.S.C. § 4205 (a) it is provided that a prisoner serving a term of more than one year shall (unless otherwise provided) be eligible for release on parole after serving one third of his term. Section 4205(b) provides two methods by which a prisoner can be made eligible for parole after serving less than one third of his term: (b)(1) by direct action of the sentencing judge in fixing a lesser period of time; (b)(2) by action of the sentencing judge in conferring eligibility for parole “at such time as the Commission may determine.”

Since appellant was sentenced under § 4205(b)(2), he was eligible for parole “at such time as the Commission may determine.” Guidelines for decisionmaking in this respect have been promulgated pursuant to 18 U.S.C. § 4203 (a)(1) under which appellant’s offense was classified “very high” in severity. His parole prognosis score, however, was very good (as was his institutional behavior). Putting the two together, under the guidelines’ “customary range of time to be served before release,” appellant would normally be released after serving between 26 and 36 months.

Following his hearing, the panel’s hearing summary stated that it felt “there was no excuse for subject becoming involved in this behavior due to his excellent training and education. [He was a law school graduate.] The panel feels that the subject should be required to do his eight-year sentence." Its recommendation was: “Continue for a four-year reconsideration hearing January, 1982.” (Appellant was also scheduled to receive a statutory interim hearing in January, 1980.) As reasons, the summary and the Notice of Action issued January 31, 1978, stated in part:

The action taken by the Commission was affirmed following administrative review.

Appellant first contends that he did not receive the notice and summary required by § 4206(c) (supra, note 2). The hearing panel’s Notice of Action, however, made plain the reasons for the action taken and for departure from the guidelines. In our judgment, notice and summary were adequate.

Appellant’s principal contention to the district court and on appeal is that the Commission acted in an arbitrary and capricious manner when it denied parole based on the severity of the offense in the face of the sentencing judge’s action in making appellant eligible for an early parole under § 4205(b)(2). Appellant reads the action of the sentencing judge as expressing his judgment as to the severity of the crime and in effect pre-empting the field as to that factor, thereby requiring the Commission to determine the time for release on parole solely on appellant’s subsequent institutional behavior. Appellant asserts that denial of parole under these circumstances frustrated the sentencing intention of the judge. He relies on Addonizio v. United States, 573 F.2d 147 (3d Cir. 1978); Edwards v. United States, 574 F.2d 937 (8th Cir. 1978); and Shahid v. Crawford, 430 F.Supp. 126 (M.D.Ala.1977).

The Commission, under 18 U.S.C. § 4206 (a) and its own regulations and guidelines, must give due consideration to the severity of the crime. O'Brien v. Putnam, 591 F.2d 53 (9th Cir. 1979). Here the Commission did not confine its consideration solely to that factor. It expressly took note of appellant’s institutional record and of the high score attained in the parole prognosis computation. If appellant was aggrieved, it was in the balance struck by the Commission in making its determination as to a release date that would not depreciate the seriousness of the offense, permit disrespect for the law, or jeopardize the public welfare.

Addonizio v. United States, supra, has now been reversed by the Supreme Court, —U.S.—, 99 S.Ct. 2235 , 60 L.Ed.2d 805 (1979), supra, note 1. Although the Court did not reach the merits of the Parole Commission action in that case it did have something to say on the subject. It stated:

—U.S. at—, 99 S.Ct. at 2242-2243 (footnotes omitted).

Judgment affirmed.

. Habeas corpus, an attack on the legality of incarceration and not a collateral attack on judgment, is the proper vehicle for attacking Parole Commission action. Andrino v. United States Board of Parole, 550 F.2d 519 (9th Cir. 1977). A collateral attack on the sentence imposed brought under 28 U.S.C. § 2255 will not lie. United States v. Addonizio,—U.S.—, 99 S.Ct. 2235 , 60 L.Ed.2d 805 (1979). Andrino was followed by this court in Bonanno v. United States, 571 F.2d 588 (9th Cir. 1978). Certiorari was granted in Addonizio to resolve the conflict between the decision of the Third Circuit in that case and the decision of this circuit in Bonanno . —U.S. at—n. 6, 99 S.Ct. 2235 . . By 18 U.S.C. § 4203 (a)(1) it is provided that the Commission shall “promulgate rules and regulations establishing guidelines” for the granting of parole. Guidelines so established appear as tables under 28 C.F.R. § 2.20 . That . section provides in part: “(a) To establish a national paroling policy, promote a more consistent exercise of discretion, and enable fairer and more equitable decision-making without removing individual case consideration, the U.S. Parole Commission has adopted guidelines for parole release consideration. (b) These guidelines indicate the customary range of time to be served before release for various combinations of offense (severity) and offender (parole prognosis) characteristics. The time ranges specified by the guidelines are established specifically for cases with good institutional adjustment and program progress. (c) These time ranges are merely guidelines. Where the circumstances warrant, decisions outside of the guidelines (either above or below) may be rendered.” 18 U.S.C. § 4206 (c) provides: “The Commission may grant or deny release on parole notwithstanding the guidelines referred to in subsection (a) of this section if it determines there is good cause for so doing: Provided, That the prisoner is furnished written notice stating with particularity the reasons for its determination, including a summary of the information relied upon.” . The reasons given by the Regional Commissioner on appeal differed slightly from those of the hearing panel. He stated: "After review of all relevant factors and information presented, a decision above the guidelines at this consideration appears warranted because your offense was unusually sophisticated, of unusual magnitude, and ongoing: you planned to manufacture extremely large amounts (approximately two and a half million) of amphetamine tablets weekly and to produce phencyclidine (PCP) in large quantities (100 lb. quantities). Sophistication was exhibited by the manner in which the offense was organized and, by your admission was of approximately six months duration.” . Appellant also complains that he was not supplied with advance notice of the specific grounds upon which the Commission intended to exceed the guidelines. We agree with the District Court for the Central District of California that “Neither the Guidelines nor the statute impose any such [advance notice] requirement on the Commission.” Stoller v. Tennant, 448 F.Supp. 712, 714 (C.D.Cal. 1978). Grattan v. Sigler, 525 F.2d 329 (9th Cir. 1975), relied on by appellant, is distinguishable. In Grattan the petitioner was notx,informed of the reasons for the denial of parole until after he had exhausted all his administrative appeals. “This explanation came too late to serve the purpose of the Board’s own regulations.” Id. at 331 . Here, appellant was informed of the Commission’s reasoning by the Notice of Action before he initiated his administrative appeals. . 18 U.S.C. § 4206 (a) provides as follows: “(a) If an eligible prisoner has substantially observed the rules of the institution or institutions to which he has been confined, and if the Commission, upon consideration of the nature and circumstances of the offense and the history and characteristics of the prisoner, determines: (1) that release would not depreciate the seriousness of his offense or promote disrespect for the law; and (2) that release would not jeopardize the public welfare; subject to the provisions of subsections (b) and (c) of this section, and pursuant to guidelines promulgated by the Commission pursuant to section 4203(a)(1), such prisoner shall be released.”
