In an order filed on October 29, 1992, we granted appellant’s petition for rehearing and withdrew our prior opinion. We now file this substitute opinion.
Joseph Scott Hunter appeals the denial of his petition for a writ of habeas corpus. He contends that the district court erroneously relied on the harmless error doctrine when rejecting his due process challenge to the state-imposed sentence. We affirm.
I. BACKGROUND AND PROCEDURAL HISTORY
Joseph Scott ‘ Hunter was indicted on eight counts for sexual offenses; three of the counts charged Hunter with committing forcible oral copulation. These three charges were based on incidents with two minors, Lorie D., age 12, and Michelle L., age 14.
At trial, both girls testified about the incident while Hunter asserted an alibi defense. The girls testified that after they accepted a ride with Hunter, he pulled out a gun which, unbeknownst to the girls, was unloaded. Hunter pointed the gun at Michelle’s head and told her to do what he said and she would not get hurt. Hunter told the girls that earlier that day he had robbed a bank, had been wounded, and was not afraid to use the gun. Later, Hunter took some bullets out of his pocket, loaded the gun, put it under the driver’s seat, and told the girls it would remain there.
The jury found him guilty on seven counts, including the three counts of committing forcible oral copulation, under California State Penal Code 288a(c). The jury specifically found that Hunter did not use a deadly and dangerous weapon. During deliberations, the jury required further instructions regarding the meaning of deadly and dangerous weapon.
In addition to the normal sentence under the penal code, Hunter was sentenced to consecutive terms of seven years on each of these counts via a sentencing statute, California State Penal Code section 667.-6(c). At the time Hunter committed the acts in question section 288a(c) of the Penal Code defined forcible oral copulation as committing the act “by means of force, violence, duress, menace, or fear of immediate and unlawful bodily injury”; while *346 section 667.6(c) provided for additional consecutive sentences if the crimes were committed “by force, violence, duress, menace, or threat of great bodily harm.” 1
Hunter appealed his conviction and sentence on three separate occasions yet never raised the question of whether the linguistic discrepancies between California Penal Code sections 667.6(c) and 288a(c) denied him due process. The issue was first raised in his state petitions for a writ of habeas corpus. The petitions were denied without comment by both the California Court of Appeal and Supreme Court.
II. DISCUSSION
A. STANDARD OF REVIEW
This court reviews de novo a district court’s decision on a petition for writ of habeas corpus.
Carter v. McCarthy,
B. PROCEDURAL DEFAULT
The government contends that Hunter’s argument is procedurally barred from federal habeas review because he did not raise the issue properly on direct appeal. We disagree.
The government relies on the recent United States Supreme Court decision in
Coleman v. Thompson,
— U.S. —,
In
Coleman,
the petitioner had filed a petition for a writ of habeas corpus in state court raising federal constitutional claims that he had not raised on direct appeal. The state court ruled against him on all claims. Coleman appealed but was three days late in filing his notice of appeal. The state filed a motion to dismiss the appeal based on the late filing, and the state supreme court granted the motion and dismissed the appeal virtually without comment.
Id.,
— U.S. at —-—,
The Virginia Supreme Court stated plainly that it was granting the Commonwealth’s motion to dismiss the petition for appeal. That motion was based solely on Coleman’s failure to meet the Supreme Court’s time requirements. There is no mention of federal law in the Virginia Supreme Court’s three-sentence dismissal order. It “fairly appears” to rest primarily on state law.
Id.,
— U.S. at —,
Here, Hunter did not raise his federal constitutional claims on direct appeal, but raised them in an original habeas petition filed in the California Court of Appeal. The state filed an opposition, arguing both the merits and invoking the rule, which exists in California as elsewhere, that failure to raise an issue on direct appeal amounts to a waiver thereof.
See In re
*347
Sterling,
The state courts’ terse dismissals of the habeas petitions do not disclose whether they were based on state or federal law. Certainly the
pro forma
orders do not “fairly appear[ ] to rest primarily on federal law, or to be interwoven with the federal law.”
Coleman,
— U.S. at —,
We also are unable to employ the presumption set forth in
Ylst v. Nunnemaker,
— U.S. —,
The unavailability of the
Harris v. Reed
or
Ylst v. Nunnemaker
presumption does not end our inquiry, however. Absent a presumption, “federal habeas courts must ascertain for themselves if the petitioner is in custody pursuant to a state court judgment that rests on independent and adequate state grounds.”
Coleman,
— U.S. at —,
The United States Supreme Court has acknowledged that discerning the basis of an unexplained state court order is not an easy task.
Ylst,
— U.S. at —,
In Coleman itself, although the order was unexplained, the nature of the disposition (“dismissed” rather than “denied”) and surrounding circumstances (in particular the fact that the state had rested its argument entirely upon a procedural bar), indicated that the basis was procedural default.
Id.; see also Coleman,
— U.S. at —,
Nevertheless, the California Supreme Court in issuing its bare order had good reason to know the effect it would be given in federal court. We had visited the issue in
Harris v. Superior Court,
Our decision in Harris v. Superior Court has been in place for nearly two decades, and the California Supreme Court has never indicated disagreement with Harris s interpretation of that Court’s orders. The California Supreme Court has continued its practice of denying some petitions for habeas corpus with a citation to state authority denoting a particular state procedural ground, while citing no authority in a larger number of denials. Against the background of Harris v. Superior Court and this continued practice of the California Supreme Court, we conclude that the California Supreme Court’s summary order denying Hunter’s petition was a denial on the merits of Hunter’s constitutional claims, and not a denial on a state procedural ground.
Our conclusion also is supported by the fact that “sometimes the members of the court issuing an unexplained order will not themselves have agreed upon its rationale, so that the basis of the decision is not merely undiscoverable but nonexistent.”
Ylst,
— U.S. at-,
Accordingly, the California Supreme Court’s unexplained denial of Hunter’s habeas corpus petition cannot be said to rest on independent and adequate state procedural grounds. We conclude therefore, that federal review of the merits of Hunter’s habeas petition is not barred by his failure to raise his constitutional claims on direct appeal.
C. DUE PROCESS CHALLENGE
In a constitutional due process challenge, we apply a harmless error analysis as found in
Rose v. Clark,
Hunter claims the jury based his convictions for forcible oral copulation on a finding of fear of immediate and unlawful bodily injury under California State Penal Code section 288a(c), a lesser standard than the threat of great bodily injury found in California State Penal Code section 667.-6(c), the sentencing enhancement statute. He asserts, therefore, that the court’s additional consecutive sentences were not authorized by the enhancement statute, are in excess of that authorized by state law, and thus denied him due process of the law. The government claims that the failure of the jury to return a special finding regarding oral copulation by means of threats of great bodily harm is harmless error.
*349 As we noted above, the discrepancy between section 288a(c) and section 667.6(c) existed only between 1980 and 1985. The California courts have on many occasions addressed the problem we confront here: a defendant convicted under section 288a(c) and sentenced under 667.6(c) even though the jury did not return a separate finding as to violation of section 667.6(c).
Early California cases held that at sentencing the judge could not invade the province of the jury by determining the factual issue of the degree of force utilized by a felon convicted under section 288a.
See People v. Riffey,
Hunter admits on appeal that the basic facts are not in dispute. Evidence at trial revealed that Hunter picked up the young victims and drove them to a secluded spot. He pointed the gun, albeit unloaded, at the head of one of the girls and told her he and others had robbed a bank earlier in the day, resulting in several people, including himself, being shot. He stated that he had used the gun and was not afraid to use it again, but if she did what he said, she would not get hurt. He then loaded the gun and placed it under the car seat. He forced the victims to perform the sexual acts for which he is charged. The victims testified that they were afraid of Hunter “because he was big” and “because he had a gun.” Although he did not directly use the gun while performing the acts, a reasonable jury could only find that the presence of the gun combined with all the other circumstances constituted a threat of great bodily harm to the victims. Thus, had the jury been properly informed of the differing standards in the statutes, the result would have been the same; the error therefore was harmless beyond a reasonable doubt.
See Rose,
Hunter points out that the jury found that the gun was not capable of being used to inflict great bodily injury, presumably because it found that the gun was not loaded. But that finding is irrelevant to the question whether Hunter used the gun to threaten great bodily harm.
III. CONCLUSION
We conclude that the California Supreme Court’s denial of Hunter’s petition does not procedurally bar review of his constitutional claims in a federal court habeas corpus proceeding. However, any error which occurred during his trial was harmless beyond a reasonable doubt and therefore his habeas corpus petition must be denied.
Judgment affirmed.
Notes
. This discrepancy between section 288a(c) and 667.6(c) existed from 1980 to 1985 because of an apparent oversight by the California legislature: when it changed the language of section 288a(c) in 1980, it did not change the corresponding language of section 667.6(c).
. Although
Harris v. Superior Court
considered whether an unexplained order satisfied the exhaustion requirement, we also have applied its rule to procedural default cases.
