Brief Fact Summary. The Defendant, Gordon Patterson, Jr. (Defendant), killed the paramour of his estranged wife by shooting him twice in the head. The Defendant admitted to the killing, but raised the affirmative defense of extreme emotional disturbance, which he had the burden of proving at trial. The jury found him guilty of murder.
Synopsis of Rule of Law. Burdening a defendant with proving the affirmative defense of extreme emotional disturbance does not violate the Fourteenth Amendment to the United State Constitution’s (Constitution) Due Process Clause.
Held. No. The Due Process Clause of the Constitution requires that the prosecution prove every element of the offense beyond a reasonable doubt, which the State did here. To require the prosecution to then disprove the non-existence of all mitigating circumstances would be “too cumbersome, too expensive, and too inaccurate.” Therefore, since nothing was presumed or implied against the Defendant and the prosecution proved every element of the crime beyond a reasonable doubt, the Due Process Clause of the Constitution is not violated in making the Defendant prove his affirmative defense by a preponderance of the evidence.
Dissent. The Due Process Clause of the Constitution dictates that the prosecution must bear the burden of proving the existence or absence of extreme emotional disturbance.

Discussion. The prosecution bears the burden of proving beyond a reasonable doubt only those elements of the offense charged. The Defendant must therefore prove any affirmative defenses.
