Appellant, Dale S. Pierre (hereinafter “Pierre”), appeals from the order of the Third Judicial District Court which dismissed his petition for postconviction relief.1 See companion case, Andrews v. Morris, Utah, 607 P.2d 816, also filed this date, the issues resolved therein being pertinent and generally dispositive of this appeal.
Pierre’s petition for habeas corpus is substantially identical in context to that of Andrews in that it also challenges his commitment under the sentence of death on the general grounds that his rights under the Constitution of the United States and that his sentence of death by shooting violates his state and federal constitutional rights. Likewise, his general assertions of error are virtually the same as those advanced in Andrews, i. e., the trial court’s denial of an evidentiary hearing and failure to apply new case law deemed to afford a basis for habeas corpus relief. However, Pierre’s specific assertions of error prompt us to address them although we do so at the risk of being somewhat redundant.
Pierre asserts that the trial court erred in dismissing his petition in the following respects: (1) that the petition raised issues that could not have been raised on direct appeal; (2) that the Utah sentencing procedure is constitutionally infirm; (3) that the imposition of the death penalty in the face of unresolved factual and legal issues constitutes a denial of due process; (4) that the doctrine of res judicata was applied rather than collateral estoppel and that no evidence was before the court to support the application of either doctrine; (5) that it does not appear to a certainty that no state of facts could be proved to support the claim for relief; and (6) that the court improperly converted the motion to dismiss to one for summary judgment.
In support of his initial assertion of error, Pierre advances four contentions why the issues raised in his petition could not have been presented at the time of the direct appeal in State v. Pierre, Utah, 572 P.2d 1338 (1977). The first thereof is that this Court’s decision in Pierre, supra, raised the issues as to: (a) the discretion of the sentencing authority in imposing the death penalty; (b) the need for specification by the sentencing authority of the aggravating circumstances found to exist; (c) the guidance to be given the sentencing authority in reaching its decision; (d) the nature and scope of judicial review; and (e) the burden of proof applicable at the sentencing phase of the trial.
With the exception of the issue as to the need for a specification of the aggravating circumstances, a cursory review of the record and our opinion in Pierre reveals that none of the foregoing issues arose from the decision in Pierre, but in fact they were part and parcel of it, having been raised by Pierre at that time and ruled upon. He has simply reframed the same issues in the petition now before us. As to any need for a specification of aggravating circumstances, the case of Gardner v. Florida, 430 U.S. 349, 97 S.Ct. 1197, 51 L.Ed.2d 393 (1977) determined that so long as the record reveals the evidentiary basis for the imposition of the death penalty so as to insure that the appellate court may conduct a comprehensive *814review of the proceedings and insure that the penalty, was not imposed arbitrarily or capriciously, the concerns of Furman v. Georgia, 408 U.S. 238, 92 S.Ct. 2726, 33 L.Ed.2d 346 (1972), are met. We specifically addressed this same issue in Andrews and for the reasons stated therein we reject Pierre’s contentions here.
Pierre’s second contention as to why the issues now presented could not have been presented previously is that they stem from certain recent decisions of the United States Supreme Court.2 We reviewed those cases in Andrews and concluded that all arise in a factual context clearly distinguishable from this case and none of them establishes a significantly different test than set forth in Furman v. Georgia, 408 U.S. 238, 92 S.Ct. 2726, 33 L.Ed.2d 346 (1972), Gregg v. Georgia, 428 U.S. 153, 96 S.Ct. 2909, 49 L.Ed.2d 859 (1976), Proffitt v. Florida, 428 U.S. 242, 96 S.Ct. 2960, 49 L.Ed.2d 913 (1976), and Jurek v. Texas, 428 U.S. 262, 96 S.Ct. 2950, 49 L.Ed.2d 929 (1976). Consequently, and for the further reasons stated in Andrews, Pierre’s reasoning is rejected.
Pierre’s third contention as to why issues are now presented that could not have been previously presented is that he and Andrews are the first persons faced with death under the 1973 statute and that they are hence entitled to have their offenses compared with those in other Utah death penalty cases with a view toward determining if they are sufficiently aggravated as to warrant the death penalty.
The foregoing contention was addressed in Spinkellink v. Wainwright, 578 F.2d 582 (5th Cir. 1978) cert. denied, wherein it was determined that it is not necessary to undertake such a case-by-case comparison. That conclusion rests upon that court’s interpretation of Proffitt v. Florida, supra. In Proffitt, the court determined that the Florida statute is constitutional “on its face” and that the Florida system satisfies the constitutional deficiencies identified in Furman. With this we do not disagree. Consequently, we deem the issue to be one of law, not fact, and hence one that could have been presented on direct appeal. In any event, the trial court correctly dismissed as a matter of law since the Utah statute is clearly constitutional “on its face” and we determined in Pierre that it was meticulously followed.
The fourth contention advanced, that the law pertaining to capital punishment is highly technical and hence some issues have not been apparent to counsel and legal commentators, has no merit. Such a “wait and see” approach was expressly rejected in Spinkellink and we deem it to be an obviously untenable position since its adoption would totally frustrate the criminal process.
We now turn to Pierre’s second assertion of error, viz., that the standard of proof required in the sentencing phase of the trial is unconstitutional in that it: (a) shifts the burden of proof to the defendant; (b) permits the sentencing authority to exercise unguided discretion; and (c) is in effect a mandatory penalty of death in those instances where little or no mitigating circumstances are shown.
We note at the outset that the standard of proof issue was raised on direct appeal in Pierre and that we then adopted the totality of proof test as established in Proffitt v. Florida, wherein the matter was stated as follows:
The directions given to the judge and jury by the Florida statute are sufficiently clear and precise to enable the various aggravating circumstances to be weighed against the mitigating ones. As a result, the trial court’s sentencing discretion is guided and channeled by a system that focuses on the circumstances of each individual homicide and individual defendant *815in deciding whether the death penalty is to be imposed. [Emphasis added.]
Contrary to Pierre’s contention, the burden of proof is not shifted to the defendant under the Utah sentencing procedure. The defendant is simply afforded the opportunity of presenting any evidence he may have in mitigation. The most that can be said for such a procedure is that the defendant then has the “burden” of going forward, but only if he so desires. The burden of proof remains at all times on the prosecution.
In regard to the remaining contention that the death sentence can be mandatorily imposed, such is without merit under the facts of this case for Pierre did pursue his right to offer evidence of mitigating circumstances and argued the issue to the jury. As we noted in Pierre, the matters which he offered in mitigation were “most minimal — even from the point of view of inference.” Also, for the reasons more fully stated in Andrews, we deem the case of Roberts v. Louisiana, 428 U.S. 325, 96 S.Ct. 3001, 49 L.Ed.2d 974 (1976) cited by Pierre as wholly inapposite.
Pierre’s third assertion of error, viz., that it is unconscionable and a denial of due process to impose the death penalty where there are unresolved legal and factual issues pending, is without merit for, in accord with our foregoing discussion, we find no such issues to be pending. No issues have been made to appear such that “it would be wholly unconscionable not to re-examine.” 3 The severity of the death penalty standing alone does not render it unconscionable for this Court to deny further review. Rather, it is the substance of the claims asserted that governs.4
Pierre’s fourth assertion of error actually concerns the trial court’s application of the doctrine of waiver rather than either of the doctrines of res judicata or collateral estop-pel to which he refers. This issue was extensively discussed in Andrews and for the reasons stated therein we reject his contentions.
Pierre’s fifth and sixth assertions of error both pertain to the procedural propriety of the trial court’s granting of the motion to dismiss. Likewise, these issues were addressed in Andrews and for the reasons stated therein we deem his contention to be without merit.
We reaffirm our holding in Pierre that the statutory system under which the sentence of death was imposed does not violate the Constitutions of Utah or of the United States and that all claimed errors are without merit. Following said statutory procedure, and given the especially heinous nature of the murders in this case, no rational judge or jury could have returned a verdict of other than guilty, nor could they have determined other than that the aggravating circumstances thereof clearly outweighed those in mitigation.
We affirm the order of the trial court dismissing the petition.
