Riggins v. Nevada

Background

A man accused of murdering another was arrested, found competent to stand trial, and tried after receiving large doses of the antipsychotic drug Mellaril in jail. He testified, raised an insanity defense, and was convicted of murder and robbery and sentenced to death. Before trial he asked the judge to stop the medication so jurors would see his unmedicated appearance; the judge denied the request in a brief order and the medication continued at high doses during trial.

Reasoning

The Court examined whether forcing antipsychotic medication on a detainee without explicit findings violated the person’s right to a fair trial and to avoid unwanted drugs. The Nevada courts and the parties described the post-order dosing as involuntary, and medical testimony at the hearing showed that high doses could cause drowsiness, sedation-like effects, and other changes that might alter courtroom demeanor or the ability to assist counsel. Because the trial court made no findings showing that involuntary treatment was necessary, medically appropriate, or that less intrusive options had been considered, the Court concluded the record left an unacceptable risk that the medication prejudiced the trial and reversed.

Real world impact

The decision sends the case back for further proceedings and requires courts to make clear, specific findings before allowing forced antipsychotic medication during pretrial or trial proceedings. It recognizes a protected interest in avoiding such drugs and allows defendants to challenge convictions when involuntary medication raises substantial risk of trial prejudice.

Dissents or concurrances

A concurring Justice stressed that involuntary medication to render defendants competent is especially suspect without an extraordinary state showing. A dissenting Justice argued the record showed a fair trial and disputed using Harper-based findings to reverse the conviction.
