Gregory B. La Rue, a state prisoner at the Correctional Training Facility, Soledad, California, appeals the district court’s denial of his habeas corpus petition filed pursuant to 28 U.S.C. § 2254. La Rue contests the validity of his conviction for second degree felony murder, which rested upon the offense of felony child abuse. He argues that recent decisions of the California Supreme Court and Court of Appeal, which preclude a conviction for felony murder when the underlying offense is child abuse, require his release. La Rue asserts that the failure to apply these decisions retroactively to his conviction violates the equal protection and due process clauses of the fourteenth amendment.
We have jurisdiction under 28 U.S.C. § 2253, and we affirm.

FACTS
In 1980, a jury convicted La Rue of second degree felony murder in violation of California Penal Code § 187. The underlying offense charged was felony child abuse. The victim, two-year-old Cherise, either was placed or voluntarily climbed into a bathtub of scalding water, where she received severe burns and suffered respiratory arrest. Allegedly in an effort to revive her, La Rue tied a sock around her neck so that he might massage her throat. Cherise died several days later. The cause of death was brain damage due to oxygen starvation and a severe infection arising from her burns.
La Rue appealed his conviction, which the California Court of Appeal affirmed in 1981. In 1984, after his conviction had become final, the California Supreme Court held in another case that a person could not be convicted of murder by application of the felony murder rule when the underlying offense charged is assaultive child abuse.
See People v. Smith,
After Smith and Benway were decided, La Rue filed a petition for a writ of habeas corpus in the California Court of Appeal. He contended that under the Smith and Benway cases, he should not have been convicted of murder because the underlying offense could not serve as the predicate felony for his felony murder conviction. The California Court of Appeal denied the petition and the California Supreme Court denied a petition for review. La Rue then filed a petition for a writ of habeas corpus in the California Supreme Court. Again he alleged that under Smith and Benway he was not guilty of felony murder and the failure of the state to grant his petition denied him due process. The California Supreme Court denied this petition by a “postcard denial” without opinion. La Rue then filed this petition for a writ of habeas corpus in federal district court. The district court concluded that La Rue’s retroac-tivity argument failed for two reasons. First, the California Supreme Court already had rejected this argument on the merits. Second, because it was possible that La Rue committed a non-assaultive child abuse, the decisions La Rue cited in support of his position could not be relied upon. The district court denied the petition and this appeal followed.

STANDARD OF REVIEW
We review de novo a district court’s denial of a petition for writ of habeas corpus.

ANALYSIS
La Rue’s appeal turns on whether the Smith and Benway cases, decided after his conviction became final, apply retroactively to his case. Our review is limited to the federal constitutional issues. 28 U.S.C. § 2254(a). A discussion of the state law background, however, is essential to an understanding of the federal claims.
In holding a person cannot be convicted of murder under the felony murder rule when the underlying felony is assaultive child abuse, the California Supreme Court in
People v. Smith
applied the so-called merger doctrine, which prohibits giving a felony murder instruction when the underlying felony is “an integral part of the homicide.”
Smith,
By limiting the
Smith
holding to assaultive child abuse, the California Supreme Court left open the possibility that a non-assaultive (that is, negligent or passive) child abuse might support a felony murder instruction.

at 808 & n. 7,
La Rue argues that the Benway decision invalidates the earlier Shockley case and, consequently, the district court erred in finding Shockley was the controlling precedent. 1 We need not decide whether the district court erred in applying Shockley. As we explain infra, the California Supreme Court has foreclosed the issue by deciding not to apply Smith and Benway retroactively.
1. Equal Protection
La Rue argues that
Smith
and
Benway
must be applied retroactively to his case under the holding of the California Supreme Court in
People v. Mutch,
While we agree that once a state has established a rule it must be applied evenhandedly,
Johnson v. Arizona,
While it is clear that the California Supreme Court can refuse to apply Smith and Benway retroactively to La Rue’s case without violating his rights under the equal protection clause of the fourteenth amendment, the question remains whether the Supreme Court of California has made this decision. That court’s postcard denial of La Rue’s petition for a writ of habeas corpus was a summary denial without opinion.
In
Harris v. Superior Court,
2. Due Process
La Rue’s final argument is that the state court’s decision not to apply
Smith
and
Benway
retroactively violates his due process rights. As we have stated in response to La Rue’s equal protection claim, however, the decision of a state court to make a ruling retroactive, prospective only, or permit limited retroactivity raises no federal constitutional issue in the context of this case.
Wainwright v. Stone,
AFFIRMED.
Notes
. The district court concluded that La Rue might have committed either an assaultive or non-assaultive child abuse. The court held that La Rue’s conviction was proper because

v.
Shockley,
. La Rue argues that we are wrong to treat a postcard denial as a ruling on the merits. He asserts that there can be no "ruling” under California law absent a written opinion. In support of this contention, however, La Rue cites cases involving the doctrine of law of the case.
See, e.g., People v. Pacini,
These cases are inapposite. Law of the case concerns the effect of an appellate court’s ruling on a legal issue on subsequent proceedings in the same suit.
Richer,
La Rue’s argument is flawed for another reason. The law of the case decisions suggest that summary denial of certain writs could be on grounds other than the merits.
