Clark v. Arizona
Issues
Whether Arizona's insanity law, as set forth in A.R.S. § 13-502 (1996) and applied in this case, violated Petitioner's right to due process under the United States Constitution, Fourteenth Amendment?
Whether Arizona's blanket exclusion of evidence and refusal to consider mental disease or defect to rebut the state's evidence on the element of mens rea violated Petitioner's right to due process under the United States Constitution, Fourteenth Amendment?
On June 21, 2000, 17-year-old Eric Clark shot and killed Flagstaff, Arizona Police Officer Jeffrey Moritz. Brief for Petitioner at 2. At the time, Clark had been suffering from delusions and hallucinations and had been diagnosed as suffering schizophrenia and psychosis. Id. At trial, he attempted to present evidence of his mental illness in order to negate the mens rea knowledge and intent elements of first degree murder. The government, however, argued successfully that under Arizona's definition of insanity (A.R.S. § 13-502(A)) and State v. Mott, evidence of Clark's mental illness was impermissible to negate the mens rea of the crime. Clark was subsequently convicted of first degree murder. He appeals the conviction, arguing that preventing him from using evidence of his mental disease to negate the mens rea of the crime violates his Due Process rights under the Fourteenth Amendment.
