The sole issue in this case is whether the charge on voluntary manslaughter was plain error.
The same charge was found to be plain error in State v. Muscatello (1977), 57 Ohio App. 2d 231 [11 O.O.3d 320]. The Court of Appeals for Cuyahoga County reversed Muscatello’s murder conviction for this reason as well as two other assignments of error not relevant to this opinion. We affirmed that court’s decision in State v. Muscatello (1978), 55 Ohio St. 2d 201 [9 O.O.3d 148]; however, we did not address the plain error issue.
Absent plain error, the failure to object to improprieties in jury instructions, as required by Crim. R. 30, is a waiver of the issue on appeal. State v. Williams (1977), 51 Ohio St. 2d 112 [5 O.O.3d 98]; State v. Humphries (1977), 51 Ohio St. 2d 95 [5 O.O.3d 89],
The trial court’s instruction on voluntary manslaughter at least inferentially placed upon the defendant the burden to prove beyond a reasonable doubt the emotional stress, as described in former R.C. 2903.03. After the *14amendment of R.C. 2901.05, effective November 1, 1978, the defendant had the burden of proof by only a preponderance of the evidence.
We agree with the court of appeals that there was sufficient evidence to raise the issue of the mitigating circumstances of extreme emotional stress, which, if believed by the trier of fact, would support a verdict of voluntary manslaughter. We are also of the opinion that under the facts of the instant case the charge on the lesser included offense of voluntary manslaughter was not inconsistent with the complete defense of accident.
We have held that a jury instruction which improperly places the burden of proof upon a defendant “does not constitute a plain error or defect under Crim. R. 52(B) unless, but for the error, the outcome of the trial clearly would have been otherwise.” State v. Long (1978), 53 Ohio St. 2d 91 [7 O.O.3d 178], paragraph two of the syllabus. In the same case we concluded that the plain error rule should be applied with utmost caution and should be invoked only to prevent a clear miscarriage of justice.
The evidence on extreme emotional stress was barely sufficient to warrant a charge on voluntary manslaughter. The state’s evidence of murder was overwhelming.
The facts in this case fall far short of meeting the criteria for plain error. We see no miscarriage of justice in this case.
The judgment of the court of appeals is reversed.
Judgment reversed.
