Mental Retardation and the 8th Amendment

In 2002, the United States Supreme Court determined that the Eighth Amendment to the U.S. Constitution's prohibition against cruel and unusual punishment bars the execution of mentally retarded persons. Atkins v. Virginia, 536 U.S. 304 (2002).  The Court reasoned that neither retribution nor deterrence could be achieved by executing mentally retarded persons and that, because mentally retarded persons have a reduced ability to participate in their own defense, there is an enhanced risk that they would be sentenced to death unnecessarily.  However, the Supreme Court left it to the individual states to determine which offenders are, in fact, retarded, in order to enforce this constitutional restriction. 

In Ex Parte Briseno, the Texas Court of Criminal Appeals established non-mandatory guidelines to determine “that level and degree of mental retardation at which a consensus of Texas citizens would agree that a person should be exempted from the death penalty.” 135 S.W. 3d 1 (2004).  If an offender meets the definition of mental retardation, then the guidelines are designed to consider some more subjective criteria. The definition of mental retardation that the CCA adopted was:

(1) Significantly subaverage general intellectual functioning, generally shown by an IQ of 70 or less, (2) accompanied by related limitations in adaptive functioning, (3) the onset of which occurs prior to the age of 18.

If a person meets that definition, the following guidelines were designed to help factfinders in criminal trials focus upon weighing the evidence as indicative of mental retardation or of a personality disorder:

Did those who knew the person best during the developmental stage – his family, friends, teachers, employers, and authorities – think he was mentally retarded at that time, and, if so, did they act in accordance with the determination?

Has the person formulated plans and carried them through, or is his conduct impulsive?

Does his conduct show leadership, or does it show that he is led around by others?

Is his conduct in response to external stimuli rational and appropriate, regardless of whether it is socially acceptable?

Does he respond coherently, rationally, and on point to oral or written questions, or do his responses wander from subject to subject?

Can the person hide facts or lie effectively in his own or others’ interests?

Putting aside any heinousness or gruesomeness surrounding the capital offense, did the commission of that offense require forethought, planning, and complex execution of purpose?

The CCA cautioned that these factors should not be considered in isolation, but rather in the context of the concerns expressed by the Supreme Court in the Atkins decision. 

Last week, the CCA considered a capital murder habeas case (Ex Parte Sosa) wherein the applicant alleged that he was mentally retarded at the time of the offense.  The habeas court found that the applicant established mental retardation.  The CCA cited some inconsistencies and ultimately remanded the case back to the convicting court for the judge gather more information and consider the Briseno factors in determining whether the applicant was (or is) indeed mentally retarded.

This is an interesting area of law to me.  I've had the occasion to dig into some literature on autism recently, and at first glance it would seem that some autistic indviduals (those that are higher on the spectrum) might satisfy the factors laid out by the CCA.  Of course, the Briseno and Atkins cases deal only with the death penalty and capital punishment, but as far as retribution and deterrence go, this could be good extenuation and mitigation evidence for the factfinder to consider in other cases as well.

A Simple Truth (Revisited)

In September of 2010, the 3rd Court of Appeals (Austin) reversed the sexual assault conviction of Mark Barshaw because the trial court allowed the following testimony of an MHMR expert regarding the truthfulness of mentally retarded individuals:

It's been my experience that folks with mental retardation can be painfully honest, really. I mean, it's like a little kid who looks at somebody and says in the supermarket, 'You're really old,' or, you know, whatever little kids do.

See our prior post HERE.  The State appealed the 3rd Court’s reversal and now, in an opinion released on 29 June 2011, the Texas Court of Criminal Appeals reversed the Court of Appeals.

Apparently troubled by the less-than-thorough harm analysis conducted by the lower court, the CCA explained:

Even in cases in which credibility is paramount, Texas courts have found harmless error when the inadmissible expert testimony was only a small portion of a large amount of evidence presented that the jury could have considered in assessing the victim’s credibility. Upon reviewing the record as a whole, we find that additional evidence exists that should have been considered in the court of appeals’s harm analysis, as is required by [our previous caselaw].

With that, the CCA remanded the case back to the 3rd Court of Appeals to conduct a full harm analysis. A shot across the bow perhaps? I think the odds are heavily in favor of the Court of Appeals changing its mind on this one. We’ll see.

A Simple Truth: Sexual Assault Conviction Reversed for Improper Expert Testimony

It's been my experience that folks with mental retardation can be painfully honest, really.  I mean, it's like a little kid who looks at somebody and says in the supermarket, 'You're really old,' or, you know, whataver little kids do.

That was part of the testimony of an MHMR expert at the sexual assault trial of Mark Barshaw.  Barshaw was accused of sexually assaulting a mentally retarded victim, who was 21 years-old at the time, but functioned at approxiamtely a 10 year-old level.  Upon hearing this testimony, the defense counsel objected, "You can't have somebody come in and testify to a class of people are truthful."  The State responded by stating that it was simply trying to show how mentally retarded persons "adapt" and that the testimony also went to show that "she's incapable of either appraising the the situation or the nature of the act."  The trial judge allowed the testimony to continue.

...again, it's been my experience in the hundreds and hundreds of people with mental retardation that I've seen, that it's more going to be that they're painfully honest.  They haven't learned the social skills and probably never will to know when you should lie or when it would be socially appropriate to not tell the truth because it might hurt someone's feelings, or things of that nature, to hold things back.

In allowing the testimony of the MHMR expert, the trial judge abused its discretion, said the 3rd District Court of Appeals (Austin).  The Court explained that the Texas Court of Criminal Appeals has held that evidence rule 702 "does not permit an expert to give an opinion that the complainant or a class of persons to which the complainant belongs is truthful."  Yount v. State, 872 S.W.2d 706, 712 (Tex. Crim. App. 1993).  Such an expert, is essentially telling the jury that they can believe the victim in the instant case.  This, held the CCA, "is not 'expert' testimony of the kind which will assist the jury under rule 702."  Id. at 711.

The Court also cited the CCA case Schutz v. State.  957 S.W.2d 52 (Tex. Crim. App. 1977).  In Schatz, the CCA explained that:

children and mentally retarded persons are viewed by society as "impaired." When such a witness is expected to testify, expert testimony should be permitted in the offering party’s case in chief concerning the ability of the class of persons suffering the "impairment" to distinguish reality from fantasy and to perceive, remember, and relate the kinds of events at issue in the case.  The court emphasized that such testimony should be limited to the “impaired” class’s ability to accurately relate events and should not extend to the class’s tendency to do so; the latter would violate the holding in Yount.

Id. at 70 (emphasis added).  Having violated the CCA holdings in Yount and Schutz by allowing the expert to testify that mentally retarded persons are, as a class, truthful, the Court found harm and reversed the sexual assault conviction.

Justice Henson dissented and would have held that there was no harm in the trial judge's erroneous ruling.

Alternative Testing May Not be Substituted for IQ Testing in the Mental Retardation Claim of Death Row Inmate

Yokamon Laneal Hearn was sentenced to death for the carjacking and fatal shooting of a Dallas-area stockbroker in 1998.  His initial execution date was set for March 4th, 2004, but it was stayed due to his claim of mental retardation.  In an application for Writ of Habeas Corpus to the Texas Court of Criminal Appeals, Hearn asserts that he is mentally retarded and, pursuant to the Supreme Court holding in Atkins v. Virginia, 536 U.S. 304 (2002), constitutionally exempt from execution.

According to Texas statutes and caselaw, mental retardation is defined by:

(1) significantly subaverage general intellectual functioning; (2) accompanied by related limitation in adaptive functioning; (3) the onset of which occurs prior to the age of 18.

Under the DSM-IV, the first prong (significantly subaverage general intellectual functioning) is defined as an IQ of about 70 or below (with a 5 point margin of error).  In this case, Hearn was administered several IQ tests, both by the State and the defense.  His scores ranged from 74 to 93, and it could not be clearly established that his IQ was about 70 or below.  As such, he searched for an alternative in order to establish subaverage intellectual functioning.

To support his claim of mental retardation, Hearn attempts to use neuropsychological measures to wholly replace full-scale IQ scores in measuring intellectual functioning.  The doctor who performed the testing testified that:

Neuropsychological testing, together with the diagnosis of fetal alcohol syndrome, has demonstrated that the significant limitations I have identified in Mr. Hearn's adaptive behavior are, nevertheless, a product of intellectual deficits...I am satisfied that Mr. Hearn has mental retardation.

The Court of Criminal Appeals, however, is not yet willing to accept new testing measures for mental retardation:

We hold that alternative assessment measures can not be substituted for full-scale IQ scores.

The Court notes in its opinion that its guidelines are judicially created because the Texas Legislature has yet to enact guidelines for enforcing the Supreme Court's Atkins mandate.  So, unless and until, the legislature decides to take up the issue, a full-scale IQ score of about 70 (give or take 5) is what will get your foot in the door.  Anything less, regardless of what other testing may reveal, and the application will be dismissed.

There is no news yet about a future execution date for Hearn.
