This is an appeal in a habeas corpus proceeding. Petitioner, an inmate of the Oregon State Penitentiary, challenges the decision of the State Board of Parole and Probation not to consider him for parole until February 1980. The circuit court rejected petitioner’s arguments and found the parole board’s action was valid.

In November 1960 a bizarre double murder took place in Portland, Oregon known as the Peyton-Allan murders. In 1962 petitioner was convicted of armed robbery and sentenced to 15 years in the Oregon State *248 Penitentiary. In June 1967 lie was paroled. In August 1968 lie was charged with the Peyton-Allan murders, and in March 1970 he was convicted in that' connection on counts of first degree and second degree murder and received sentences of life and 25 years, to run consecutively. His convictions were affirmed by this court. State v. Brom, 8 Or App 598, 494 P2d 434, Sup Ct review denied (1972). At that time a person convicted of murder in the first degree was not eligible for parole until he had served at least 10 years of his sentence. Former OES 144.230. In August 1970 the paróle board set February 1980 as the date for considering whether Brom shotdd be released on parole. The 1971 legislature repealed former OES 144.230. Oregon Laws 971, ch 743, § 432.

In May 1972 the parole board considered setting an earlier date for Brom’s parole hearing. After deliberation, the board refused' to change the parole 'consideration date. Brom testified that at the May meeting he requested that the board postpone its decision until he could present more information on a proposed parole program, and the board granted this request. One board member testified that the board reached a decision not to change the-date and so informed Brom.

' On August 8, 1972 Douglas Tatting and Dr. John'Blaylock, residents of Hawaii, appeared before two members' of the board at a regular meeting and presented detailed information about a proposed parole program fór Brom in Hawaii. It appears to have substantial merit. At the conclusion of this presentation the hoard .again -decided not to change -the. February 1980'date for considering Brom for parole. ① . •

*249 . Petitioner has specifically challenged the hoard’s decision of August 8, 1972, but in substance is attacking the May 1972 decision as well. He alleges that the board’s decision is invalid because the board exercised its function erroneously and arbitrarily and exceeded its jurisdiction to the injury of substantial rights of the petitioner in several particulars.

In a recent habeas corpus case we stated:

“Decisions of the Board of Parole' and Probation are subject to judicial review on the very limited basis of whether they are arbitrary and capricious;.plaintiff has the burden of proving the Board’s decision violates this standard. Anderson v. Alexander, 191 Or 409, 229 P2d 633, 230 P2d 770 (1951); Thompson v. Cupp, 5 Or App 393, 484 P2d 858, 29 ALR2d 1051 (1971); State ex rel Gilmore v. Cupp, 1 Or App 22, 458 P2d 711 (1969): We hold this is the standard of review of a decision denying restoration pf pre-parole good time, just as it is the standard of review for any other Board decision.” Burns v. Newell, 12 Or App 621, 627, 507 P2d 414, Sup Ct review denied (1973). ②

In addition to alleging that the parole board’s decision was arbitrary, Brom further charges that the board disregarded the presentation made on his behalf by Tatting and'Blaylock and disregarded the statutory guidelines for parole consideration established in OB.S chl44. ' '

The court below made findings of fact to the effect that the board did not disregard the presentation made,on B'rom’s behalf. These findings of fact were supported by adequate evidence in the' record and *250 we may not disturb them upon appeal. Ball v. Gladden, 250 Or 485, 443 P2d 621 (1968).

The thrust of Brora’s argument that the board failed to follow the statutory guidelines for parole consideration is based on the fact that the record contains no after sentence report from either the district attorney or the sentencing judge as required by OBS 144.210. Brom argues that the failure of the board to obtain and consider these reports renders invalid the board’s decision. ③

“Within six months after the admission to the state penitentiary of a convicted person, and from time to time, the State Board of Parole and Probation shall cause to be brought before it all information regarding such convicted person.” OES 144.220.

“No prisoner in the state penitentiary shall be paroled unless it is the opinion of the board that, within a reasonable probability, the prisoner will, after parole, remain outside the institution without violating the law and that such release is not incompatible with the welfare of society.” OBS 144.240.

“Good conduct and efficient performance of duties assigned in the state penitentiary will be factors considered by the State Board of Parole and Probation in granting parole.” OBS 144.250.

2, 3. A decision denying parole could be considered arbitrary and capricious if the board failed to consider *251 available information favorable to the prisoner. It also would be possible to consider such a decision to be arbitrary and capricious where the board failed to procure any information concerning the prisoner, depending upon the facts of a particular case. However, no parole may be granted “unless it is the opinion of the board that, within a reasonable probability, the prisoner will, after parole, remain outside the institution without violating the. law and that such release is not incompatible with the welfare of society.” OBS 144.240. As indicated below, there was an adequate basis for the board’s decision; hence, the failure to obtain and consider the missing reports cannot be considered prejudicial to the petitioner absent a showing that the reports if considered would have supported his request for an early parole date.

4. The ultimate question in this appeal is: Has the petitioner proven that the board’s action was arbitrary and capricious? The two members of the board who participated in the decision stated, inter alia, they felt the crimes Brom had been convicted of were so serious that they could not vote for his early release on parole.

There was substantial evidence presented to the board to the effect that convicted murderers make the best parole risks and the incidence of recidivism in such cases is extremely low. However, the possibility of a successful parole is only one of the statutorily required factors the board must consider; the board must also consider the “welfare of society.” The record shows the parole board members were of the opinion that the early release of this prisoner, convicted of two brutal murders, would not be compatible with the welfare of society. We are not inclined to disagree with this determination, particularly in light of the recent restate *252 ment by the 1973 legislature of the standards to bo considered by tbe parole board in such situations:

“Whenever the State Board of Parole considers the release of a prisoner who, by its rules or order, is .eligible for release on parole, it shall be the policy ■of the board to order his release, unless the board is of the opinion that Ms release should be .deferred or denied because:
