Missouri v. Gates

Defendant's convictions arose from an alleged robbery during which Defendant shot and killed Mathew Haylock. During trial, Defendant attempted to present evidence that he shot Haylock in self-defense after Haylock attempted to rob him. Each time Defendant raise the issue of presenting his own version of events the circuit court denied him the right to provide such evidence. The Supreme Court reversed and remanded the case, holding that by prohibiting Defendant from presenting evidence about the ultimate issue int his case, the circuit court prevented Defendant from presenting a complete defense, in violation of his constitutional rights.
