Whether Ohio's statutory decision to require the prosecution to disprove self-defense transformed the absence of self-defense into an element of each charged offense that the Federal Constitution required the State to prove beyond a reasonable doubt.
Holding
No. Ohio's allocation of the burden of persuasion on self-defense did not itself establish a federal constitutional entitlement to habeas relief.
Reasoning
A federal habeas court may grant relief only for custody that violates federal law. Thus, if the jury instructions merely violated Ohio's own burden-of-proof statute, the error was one of state law and could not by itself support relief under 28 U.S.C. § 2254.
Winship, Mullaney, and Patterson recognize that due process may depend on how a State defines the elements of an offense. But those decisions do not mean that every fact the State elects to prove beyond a reasonable doubt automatically becomes an element of the offense for all constitutional purposes.
Ohio could choose to give defendants the benefit of requiring prosecutors to disprove affirmative defenses without redefining the absence of those defenses as elements of murder, assault, or other crimes. The Court found no concrete basis for treating Ohio's statute as having made absence of self-defense an element of the charged offenses.
