Clerk Destroys Office Equipment
Uri Underwood, a benefits clerk with severe depression and psychotic episodes, believed his supervisor persecuted him. Over several months an inner pressure to smash the supervisor's computers built beyond his ability to resist. He entered the closed office on a weekend and destroyed the equipment. Under the irresistible impulse test the jury credits expert testimony that mental illness destroyed his capacity for self-control and acquits him.
Sex Offender Civil Commitment
Uliana Ustinova, diagnosed with a long-standing sexual disorder, repeatedly molested children when stressed and testified she could not control the urge. The state seeks civil commitment after her prison term. The court finds the documented inability to control impulses satisfies the statutory dangerousness requirement and orders continued confinement.
In 1994, the Kansas Legislature enacted the Sexually Violent Predator Act, which established procedures for the civil commitment of persons who, due to a mental abnormality or personality disorder, are likely to engage in predatory acts of sexual violence. Leroy Hendricks had a long history of sexually molesting children, beginning with a 1955 conviction for indecent exposure, followed by convictions for lewdness involving a young girl in 1957, molesting two young boys in 1960, indecent liberties with a child in 1965, and taking indecent liberties with two 13-year-old boys in both 1984 and 1994.
As Hendricks neared the end of his prison term in 1994, the State filed a petition in state court seeking to have him committed under the Act. Hendricks challenged the constitutionality of the Act but did not contest that he met the statutory definition of a sexually violent predator. At trial, Hendricks testified that he suffers from pedophilia, that he is not cured, and that when he gets stressed out he cannot control the urge to molest children. The jury unanimously found beyond a reasonable doubt that Hendricks was a sexually violent predator.
The trial court determined that the Act was constitutional and ordered him committed to the custody of the Secretary of Social and Rehabilitation Services. The Kansas Supreme Court reversed the commitment order. It held that the Act violated Hendricks’ substantive due process rights because it did not require a finding that he was unable to control his violent behavior. The court did not address the Act’s procedural due process or double jeopardy claims.
The State of Kansas petitioned for certiorari, and Hendricks filed a cross-petition reasserting his federal double jeopardy and ex post facto claims. The United States Supreme Court granted certiorari on both the petition and the cross-petition.
Unity Underhill was acquitted by reason of insanity after an assault she could not resist due to mental illness. Years later she seeks release. The state must prove she remains dangerous because of an ongoing inability to control her conduct rather than mere mental illness alone.
Foucha v. Louisiana504 U.S. 71 (1992)
In 1984, Terry Foucha was charged by Louisiana authorities with aggravated burglary and illegal discharge of a firearm. Two medical doctors were appointed to conduct a pretrial examination of Foucha. The doctors initially reported that Foucha lacked mental capacity to proceed, but four months later the trial court found Foucha competent to stand trial. The doctors reported that Foucha was unable to distinguish right from wrong and was insane at the time of the offense.
On October 12, 1984, the trial court ruled that Foucha was not guilty by reason of insanity. The court found that Foucha was unable to appreciate the usual, natural and probable consequences of his acts, that he was unable to distinguish right from wrong, that he was a menace to himself and others, and that he was insane at the time of the commission of the crimes and presently insane. Foucha was committed to the East Feliciana Forensic Facility until such time as doctors recommend that he be released and until further order of the court. In 1988, the superintendent of Feliciana recommended that Foucha be discharged or released.
A three-member panel was convened at the institution to determine Foucha's current condition and whether he could be released or placed on probation without being a danger to others or himself. On March 21, 1988, the panel reported that there had been no evidence of mental illness since admission and recommended that Foucha be conditionally discharged. The trial judge appointed a two-member sanity commission made up of the same two doctors who had conducted the pretrial examination. Their written report stated that Foucha is presently in remission from mental illness but that they cannot certify that he would not constitute a menace to himself or others if released.
One of the doctors testified at a hearing that upon commitment Foucha probably suffered from a drug induced psychosis but that he had recovered from that temporary condition. The doctor testified that Foucha evidenced no signs of psychosis or neurosis and was in good shape mentally. The doctor also testified that Foucha had an antisocial personality, a condition that is not a mental disease and that is untreatable. The doctor further testified that Foucha had been involved in several altercations at Feliciana and that he would not feel comfortable in certifying that Foucha would not be a danger to himself or to other people. After it was stipulated that the other doctor would give essentially the same testimony, the court ruled that Foucha was dangerous to himself and others and ordered him returned to the mental institution. The Louisiana Supreme Court affirmed, holding that Foucha had not carried the burden placed upon him by statute to prove that he was not dangerous. The Supreme Court granted certiorari because the case presents an important issue and was decided by the Louisiana Supreme Court in a manner arguably at odds with prior decisions of this Court.
Ulric Unger, a public figure, sues a publisher for a false story. The court requires proof of actual malice. Evidence that the reporter felt an overwhelming internal pressure to publish without verification does not excuse the failure to investigate and does not defeat the constitutional standard.
Gertz v. Robert Welch, Inc.418 U.S. 323, 94 S. Ct. 2997, 41 L. Ed. 2d 789 (1974)
In 1968, Chicago police officer Richard Nuccio shot and killed a youth named Nelson. State authorities prosecuted Nuccio and obtained a conviction for second-degree murder. The Nelson family retained petitioner Elmer Gertz, a Chicago attorney, to represent them in civil litigation against Nuccio.
Respondent Robert Welch, Inc., publishes American Opinion, a monthly magazine expressing the views of the John Birch Society. In March 1969, the magazine published an article titled "FRAME-UP: Richard Nuccio And The War On Police." The article accused Gertz of participating in a Communist conspiracy to discredit local law enforcement, described him as a "Leninist" and "Communist-fronter," and claimed he had been an officer of the National Lawyers Guild, which it portrayed as a Communist organization involved in planning attacks on Chicago police during the 1968 Democratic Convention. The article contained numerous inaccuracies, including the false implication that Gertz had a criminal record.
Gertz had served as an officer of the National Lawyers Guild approximately fifteen years earlier but had no involvement in planning the 1968 demonstrations. He had never been a member of the Marxist League for Industrial Democracy or the Intercollegiate Socialist Society. The managing editor of American Opinion made no effort to verify the charges against Gertz before publication and appended an editorial introduction stating that the author had conducted extensive research.
Gertz filed a diversity action for libel in the United States District Court for the Northern District of Illinois. The district court ruled that the statements constituted libel per se under Illinois law. After a trial, the jury awarded Gertz $50,000 in compensatory damages. The district court later entered judgment for the defendant notwithstanding the verdict, applying the New York Times standard. The Court of Appeals for the Seventh Circuit affirmed.
The Supreme Court granted certiorari to review the application of constitutional standards to defamation of a private individual.
Ursula Upton burns a cross on a Black family's lawn. The city defends its bias-motivated crime ordinance by arguing the conduct reflects an uncontrollable impulse rooted in prejudice. The court strikes the ordinance because content-based restrictions on speech cannot be justified by claims of irresistible impulse.
R.A.V. v. City of St. Paul, Minnesota505 U.S. 377 (1992)
In the predawn hours of June 21, 1990, petitioner R.A.V., then a juvenile, and several other teenagers assembled a crudely made cross by taping together broken chair legs and burned the cross inside the fenced yard of a black family that lived across the street from the house where R.A.V. was staying. Although this conduct could have been punished under several Minnesota statutes carrying significant penalties, the City of St. Paul chose to charge R.A.V. under the St. Paul Bias-Motivated Crime Ordinance.
The ordinance provides that whoever places on public or private property a symbol, object, appellation, characterization or graffiti, including but not limited to a burning cross or Nazi swastika, which one knows or has reasonable grounds to know arouses anger, alarm or resentment in others on the basis of race, color, creed, religion or gender commits disorderly conduct and shall be guilty of a misdemeanor.
R.A.V. moved to dismiss the charge on the ground that the ordinance was substantially overbroad and impermissibly content-based and therefore facially invalid under the First Amendment, and the trial court granted the motion. The Minnesota Supreme Court reversed, construing the ordinance to reach only fighting words and concluding that it was not impermissibly content-based. This Court granted certiorari.
Ursula Ung, charged with murder, claims an uncontrollable impulse from mental illness. The state requires her to prove the defense beyond a reasonable doubt. The jury instruction on that burden is upheld because the Constitution permits the state to allocate the risk of non-persuasion on the volitional element.
Leland v. Oregon343 U.S. 790, 72 S.Ct. 1002, 96 L.Ed. 1302 (1952)
Leland was charged with murder in the first degree in the Circuit Court of Multnomah County, Oregon. He pleaded not guilty and gave notice of his intention to prove insanity. The jury found him guilty of first degree murder. Because the jury did not recommend life imprisonment, he received a death sentence. The Oregon Supreme Court affirmed the conviction.
The facts emerged from Leland's confessions corroborated by other evidence. He killed a fifteen-year-old girl by striking her over the head several times with a steel bar and stabbing her twice with a hunting knife. Five days after the crime, after his arrest for automobile theft, Leland asked to speak with a homicide officer. He voluntarily confessed and directed police to the body. That same day he signed a full confession and, at his own request, wrote out another confession by hand. Counsel were appointed after indictment.
Oregon law required a defendant pleading insanity to prove that defense beyond a reasonable doubt. The statute also provided that a morbid propensity to commit prohibited acts formed no defense. The specific statute stated that when the commission of the act charged as a crime is proven, the defense of insanity must be proven beyond a reasonable doubt.
The trial judge instructed the jury on lesser included offenses. The jury could return verdicts of guilty of first degree murder, guilty of second degree murder, guilty of manslaughter, not guilty, or not guilty by reason of insanity. A first degree murder verdict required unanimous agreement of all twelve jurors, while an insanity acquittal required only ten. The prosecution bore the burden to prove every element of the crime beyond a reasonable doubt throughout the trial.
The confession was produced in court five days before the defense rested its case. Counsel and expert witnesses had ample time to study it. The trial judge offered additional time for review, but the offer was refused. The record showed no prejudice from the delayed access. No assignment of error was made on this ground in the motion for a new trial.
Must an uncontrollable impulse arise suddenly to support an insanity defense?
No. The traditional irresistible impulse test expressly permits the inability to control conduct to develop gradually or exist over time. A defendant who experiences steadily mounting pressure rooted in mental illness can still satisfy the test even if the conduct was planned over weeks or months.

Does knowing an act is illegal defeat an uncontrollable impulse claim?
No. The test is volitional rather than cognitive. A defendant who understands the wrongfulness of the conduct may still be acquitted if mental illness destroyed the capacity to conform behavior to the law.

How does the uncontrollable impulse test differ from the M'Naghten rule?
The irresistible impulse test focuses on whether mental illness prevented the defendant from controlling actions. M'Naghten requires a defect in reasoning that caused inability to know the nature or wrongfulness of the act. Loss of control alone does not satisfy M'Naghten.
