Narrative Opinion Summary
This case involved an appellant who pleaded not guilty by reason of insanity and invoked his Miranda rights during arrest and interrogation. The prosecution used the appellant's post-Miranda silence as evidence of his sanity, which the U.S. Supreme Court found to be a violation of constitutional rights, referencing its decision in Wainwright v. Greenfield. Throughout the trial, the prosecution emphasized the appellant's rational behavior in invoking his rights and contacting an attorney, arguing it indicated sanity. Defense counsel did not object to this use of post-Miranda silence, leading the court to apply a plain or harmless error analysis. The Supreme Court held that such use of constitutional rights against a defendant in this manner is fundamentally unfair and violates the principle established in Doyle v. Ohio. As a result, the Court reversed the conviction and ordered a new trial, where references to the appellant's right to silence or an attorney are prohibited, ensuring that the integrity of the insanity defense is preserved.
