Does the requirement of proof of every element of a crime beyond a reasonable doubt apply to jury instructions in a state criminal trial?

It follows that jury instructions in a state criminal trial omitting the requirement of proof of every element of a crime beyond a reasonable doubt are erroneous under the Fourteenth Amendment's due process clause. (See Jackson v. Virginia (1979) 443 U.S. 307, 320, fn. 14, 99 S.Ct. 2781, 2790, fn. 14, 61 L.Ed.2d 560.)

Evidently, similar instructions merely misdefining the beyond-a-reasonable-doubt standard by effectively lowering its threshold are also erroneous under the Fourteenth Amendment's due process clause. (Sullivan v. Louisiana, supra, 508 U.S. at pp. ---- - ----, 113 S.Ct. at pp. 2080-2081.)
