Spalding, et al. (the State), appeal from an order of the district court granting a writ of habeas corpus to Gibson pursuant to 28 U.S.C. § 2254. The State contends that Gibson’s failure to object to a constitutionally infirm jury instruction during trial or on direct appeal prevented the district judge from granting this сollateral relief. We disagree and affirm.
I
On May 29, 1974, a jury found Gibson guilty of murder in .the second degree resulting from the death of a female hitchhiker. Gibson appealed his conviction on grounds other than the one asserted in his petition for writ of habeas corpus. The Washington State Court of Appeals affirmed his conviction in an unpublished opinion on June 9,1975. On that same day, the United States Supreme Court decided
Mullaney v. Wilbur,
Gibson, still assisted by counsel, filed a pеtition for review before the Washington Supreme Court on August 20, 1975, but once more the jury instruction was not raised as an issue. The Washington Supreme Court summarily rejected Gibson’s petition on October 7, 1975. Despite the four month interval between the Mullaney decision and the Washington Supreme Court’s action, there was no attempt to seek reconsideration of the state Supreme Court’s denial of Gibson’s petition.
In March of 1978, Gibson filed a personal restraint petition — -the Washington equivalent of a habeas corpus petition. He raised for the first time his contention that the jury instruсtion given at his 1974 trial violated Mullaney, and thus entitled him to a new trial. The Washington Court of Appeals denied his habeas corpus petition in an unpublished opinion on April 9, 1979. The court also denied Gibson’s motion for reconsideration of its decision. In September of 1979, the Washington State Supremе Court summarily denied Gibson’s petition for review of the court of appeals’ decision.
Gibson then sought federal habeas corpus relief pursuant to 28 U.S.C. § 2254. His sole ground for relief was that the trial court erred in giving the challenged instruc *865 tion which, he contends, was condemned by Mullaney. The district court assigned the case to a magistrate who recommended that the district court grant petitioner’s relief. The district court accepted the magistrate’s findings without comment, and issued an alternative writ requiring Gibson’s release or retrial.
II
The State argues that Gibson’s failure at both his trial and on direct appeal to attаck the suspect jury instruction was not excused by “cause” or “prejudice” sufficient to invoke the exception to
Wainwright v. Sykes,
Washington courts have developed a similar procedural rule on the appellate levеl. The Washington Supreme Court has held that “issues which could have been raised on appeal but were not, may not be used as grounds for a collateral attack on a criminal judgment.”
Petition of Myers,
We recently examined the applicability of the
Sykes
rule to a similar factual situation in
Myers v. Washington,
We then tested whether
Myers
met the
Sykes
cause and prejudice requirements, and found both clearly met.
Id.
at 360. However, whether we treat the
Sykes
rule as inapplicable to the
Myers
situation or consider those circumstances sufficient to satisfy the “cause” and “prejudice” requirements of
Sykes
is unimportant. The case before us is distinguishable from
Myers.
The Washington Court of Appeals affirmed Gibson’s conviction on the sаme day that the Supreme Court held in
Mullaney
that a jury instruction similar to the one used in Gibson’s trial was unconstitutional. With the aid of his attorney, Gibson petitioned the Washington Supreme Court for review. At that time there was no assignment of the jury instruction as error, even though the
Mullaney
opinion had been published in U.S. Law Week and the Criminal Law Reporter over two months previous to his petition. Two months later, the petition was denied by the Washington Supreme Court. Thus, this situation is clearly distinguishable from
Myers.
Gibson and his attorney had a four month period in which to raise the jury instruction issue before the Washington Supreme Cоurt. It is possible in such a situation that a defense attorney may intentionally omit an argument while preparing his appeal with the intent of saving the issue for federal habeas consideration. In addition, adherence to the contemporaneous objection rule in the instant situаtion encourages the state appeals court to enforce strictly its own rule because the state court will not be faced with the possibility that a federal habeas court will later ignore the rule and decide the constitutional question “without the benefit of [the statе’s] views.”
Sykes, supra,
433 U.S. at-90,
We conclude, however, that Gibson has made a sufficient showing of “cause” and “prejudice” to satisfy the
Sykes
rule and overcome the bar to federal habeas review. He has asserted two separate grounds for meeting the cause requirement. First, on the authority of
Myers
he argues that cause for his failure to raise the constitutional issue on direct appeal exists because the change in the law on jury instructions occurred after hе had filed his direct appeal.
See Isaac v. Engle,
Gibson also argues that his failure to object was due to the ineffective assistanсe of counsel. In
Garrison v. McCarthy,
We cannot fathom any tactical reason for Gibson’s attorney’s failure to raise the Mul-laney objection in this case. The only reason we can perceive from the record for the failure of Gibson’s attorney to call it to the attention of the state court at some point during the four-month interval between the filing of his appeal, and the court’s decision is that he was unaware of the decision. Gibson has met his burden of satisfying the cause prong of Sykes. There is no reason to *867 remand this case for an evidentiary hearing.
Gibson has also made a sufficient showing of “prejudice.” In
Myers,
we held that the prejudice prong of
Sykes
was satisfied because of “the crucial role thе challenged jury instructions could have played in securing appellant’s conviction.”
Myers, supra,
The State argues that the district court erred in finding that Gibson was prejudiced by the instruction based upon the fact that the magistrate presumed prejudicе on an inadequate record. We disagree. The jury was instructed that if the State proved a homicide beyond a reasonable doubt, the presumption was that it was a murder in the second degree. The jury was further instructed that in order to reduce the charge to manslaughter, the defendant had the burden of proving the existence of mitigating circumstances. 2 Thus, the instruction shifted the burden to the defendant on the crucial element of intent. Gibson’s defense was based upon his contention that the victim’s death was not due to any intentional act on his part, but was instead duе to the victim’s ingestion of lethal amounts of drugs and alcohol. It is impossible to determine accurately what effect the instruction had on the jury’s verdict. Given the critical role that the burden of proof plays in a criminal trial, we were justified in Myers in holding that.prejudice was demonstrated in the giving of the instruction itself. Thus, the district court could properly conclude that Gibson was prejudiced and no evidentiary hearing was necessary.
Ill
In light of our conclusion that Gibson has made a sufficient showing of “cause” and “prejudice” under Sykes, we must now consider whether the jury instruction given at his triаl unconstitutionally shifted the burden of proof to him to produce evidence sufficient to reduce the charge from second degree murder to manslaughter.
In Mullaney, the Supreme Court held unconstitutional a state rule under which juries were instructed to presume that an intentional, unlawful killing was murdеr unless the defendant proved by a preponderance of the evidence that he had acted in the heat of passion on sudden provocation. We held in Myers that an instruction similar to the one given in this case was indistinguishable from the unconstitutional instruction in Mullaney. 3 In fact, the State concedes that the challenged instruction is unconstitutional. Thus, we hold, as we did in Myers, that the jury instruction given at Gibson’s trial violated the due process clause as interpreted in Mullaney. Thus, the district court correctly issued the alternative writ requiring the release of Gibson or a new trial.
AFFIRMED.
Notes
. The Supreme Court held
Mullaney
fully retroactive in
Hankerson v. North Carolina,
[t]he States, if they wish, may be able to insulate past convictions by enforcing the normal and valid rule that failure to object to a jury instruction is a waiver of any claim of error. See, e. g., Fed.R.Crim.Proc. 30.
Id.
at 244 n.8,
. The jury was instructed as follows:
The Cоurt instructs you that where a homicide is proved beyond a reasonable doubt, the presumption is that it is murder in the second degree. If the state desires to increase the degree to murder in the first degree, the burden is on the state to produce evidence of those facts оr circumstances which call for such increase. If the defendant desires to reduce the degree to manslaughter, the burden is on him to produce evidence of those facts and circumstances which call for such reduction.
. The challenged instructions in
Myers
also shifted the burden of proof to the defense on the intent element of second-degree murder.
