Kahler v. Kansas, 589 U.S. 271, 140 S.Ct. 1021, 206 L.Ed.2d 312, 20 Cal. Daily Op. Serv. 2348, 2020 Daily Journal D.A.R. 2542, 28 Fla. L. Weekly Fed. S 87

Facts

James Kahler was charged with capital murder after he shot and killed four family members, including his estranged wife and two daughters. Prior to his trial, Kahler argued that Kansas's insanity defense was unconstitutional because it did not allow for a moral incapacity defense, which would exonerate him due to his mental illness. The trial court denied his motion, and he was convicted. During sentencing, Kahler was allowed to present evidence of his mental illness, but the jury imposed the death penalty.

Analysis

The Court emphasized that the definition of insanity is a matter for states to determine, and there is no single, universally accepted standard that must be adopted.
