Ybarra v. Warden
What's at Stake
This case presents the question of whether the execution of a capital defendant with serious mental illness violates Article I, section 6 of the Nevada Constitution, which prohibits cruel or unusual punishment. The ACLU’s Capital Punishment Project and State Supreme Court Initiative, along with the ÌÇÐÄVlogof Nevada, filed an amicus brief arguing that a plain reading of Article I, section 6 of the Nevada Constitution provides broader protections than the Eighth Amendment and should be interpreted to establish a categorical exemption from execution for this population.
Summary
In 1979, appellant Robert Ybarra Jr. was convicted of capital murder and sentenced to death by a jury. Mr. Ybarra lives with serious mental illness and the jury that sentenced him to death was not instructed that it needed to find beyond a reasonable doubt that aggravating circumstances outweigh mitigating ones, such as mental illness. Capital defendants who live with serious mental illness, like Mr. Ybarra, are more likely to be sentenced to death. This is because symptoms of their mental illness often impair trial and appellate proceedings leading to unreliability in sentencing.
The ACLU’s Capital Punishment Project and State Supreme Court Initiative along with the ÌÇÐÄVlogof Nevada filed an amicus curiae brief arguing that Article 1, section 6 of the Nevada Constitution—which prohibits cruel or unusual punishment—bars the execution of individuals with serious mental illness.
As the brief argues, executing capital defendants with serious mental illness is cruel and lacks penological justification. It further argues that executing capital defendants is unusual given evolving standards of decency and increased protections for individuals with mental illness. Amici urge the Court to recognize that executing capital defendants with serious mental illness is unconstitutional and to categorically exempt this population from execution.
