Conspiracy, Complicity, And The Scope Of Contemplated Crime, Kimberly Ferzan Jan 2022

Conspiracy, Complicity, And The Scope Of Contemplated Crime, Kimberly Ferzan

All Faculty Scholarship

One of the leading casebooks for the first-year Criminal Law course begins the mens rea discussion with Regina v. Cunningham.1 Cunningham, in need of money, decided to rip the gas meter off the residential gas pipe in his soon-to-be basement to steal the shillings inside. That Cunningham was guilty of theft was uncontroversial. The problem was that Cunningham did not turn off the gas, and it seeped into the adjacent home, partially asphyxiating the neighbor, Sarah Wade. Although the case is technically about the interpretation of the word “maliciously” in the Offences against the Person Act, the lesson students are …

Internal And External Challenges To Culpability, Stephen J. Morse Jan 2022

Internal And External Challenges To Culpability, Stephen J. Morse

All Faculty Scholarship

This article was presented at “Guilty Minds: A Virtual Conference on Mens Rea and Criminal Justice Reform” at Arizona State University’s Sandra Day O’Connor College of Law. It is forthcoming in Arizona State Law Journal Volume 53, Issue 2.

The thesis of this article is simple: As long as we maintain the current folk psychological conception of ourselves as intentional and potentially rational creatures, as people and not simply as machines, mental states will inevitably remain central to ascriptions of culpability and responsibility more generally. It is also desirable. Nonetheless, we are in a condition of unprecedented internal challenges to …

Before And After Hinckley: Legal Insanity In The United States, Stephen J. Morse Feb 2021

Before And After Hinckley: Legal Insanity In The United States, Stephen J. Morse

All Faculty Scholarship

This chapter first considers the direction of the affirmative defense of legal insanity in the United States before John Hinckley was acquitted by reason of insanity in 1982 for attempting to assassinate President Reagan and others and the immediate aftermath of that acquittal. Since the middle of the 20th Century, the tale is one of the rise and fall of the American Law Institute’s Model Penal Code test for legal insanity. Then it turns to the constitutional decisions of the United States Supreme Court concerning the status of legal insanity. Finally, it addresses the substantive and procedural changes that …

Mental Disorder And Criminal Justice, Stephen J. Morse Jan 2018

Mental Disorder And Criminal Justice, Stephen J. Morse

All Faculty Scholarship

This paper is a chapter that will appear in REFORMING CRIMINAL JUSTICE: A REPORT OF THE ACADEMY FOR JUSTICE BRIDGING THE GAP BETWEEN SCHOLARSHIP AND REFORM (Erik Luna ed., Academy for Justice 2018). The criminal law treats some people with severe mental disorders doctrinally and practically differently at virtually every stage of the criminal justice process, beginning with potential incompetence to stand trial and ending with the question of competence to be executed, and such people have special needs when they are in the system. This chapter begins by exploring the fundamental mental health information necessary to make informed judgements …

A Brief Summary And Critique Of Criminal Liability Rules For Intoxicated Conduct, Paul H. Robinson Jan 2018

A Brief Summary And Critique Of Criminal Liability Rules For Intoxicated Conduct, Paul H. Robinson

All Faculty Scholarship

This essay provides an overview of the legal issues relating to intoxication, including the effect of voluntary intoxication in imputing to an offender a required offense culpable state of mind that he may not actually have had at the time of the offense; the effect of involuntary intoxication in providing a defense by negating a required offense culpability element or by satisfying the conditions of a general excuse; the legal effect of alcoholism or addiction in rendering intoxication involuntary; and the limitation on using alcoholism or addiction in this way if the offender can be judged to be reasonably responsible …

The justice system in the United States has long recognized that juvenile offenders are not the same as adults, and has tried to incorporate those differences into law and policy. But only in recent decades have behavioral scientists and neuroscientists, along with policymakers, looked rigorously at developmental differences, seeking answers to two overarching questions: Are young offenders, purely by virtue of their immaturity, different from older individuals who commit crimes? And, if they are, how should justice policy take this into account?

A growing body of research on adolescent development now confirms that teenagers are indeed inherently different from adults, …

Predicting The Knowledge–Recklessness Distinction In The Human Brain, Iris Vilares, Michael J. Wesley, Woo-Young Woo-Young Ahn, Richard J. Bonnie, Morris B. Hoffman, Owen D. Jones, Stephen J. Morse, Gideon Yaffe, Terry Lohrenz, Read Montague Jan 2016

Predicting The Knowledge–Recklessness Distinction In The Human Brain, Iris Vilares, Michael J. Wesley, Woo-Young Woo-Young Ahn, Richard J. Bonnie, Morris B. Hoffman, Owen D. Jones, Stephen J. Morse, Gideon Yaffe, Terry Lohrenz, Read Montague

All Faculty Scholarship

Criminal convictions require proof that a prohibited act was performed in a statutorily specified mental state. Different legal consequences, including greater punishments, are mandated for those who act in a state of knowledge, compared with a state of recklessness. Existing research, however, suggests people have trouble classifying defendants as knowing, rather than reckless, even when instructed on the relevant legal criteria.

We used a machine-learning technique on brain imaging data to predict, with high accuracy, which mental state our participants were in. This predictive ability depended on both the magnitude of the risks and the amount of information about those …

Criminal Law And Common Sense: An Essay On The Perils And Promise Of Neuroscience, Stephen J. Morse Dec 2015

Criminal Law And Common Sense: An Essay On The Perils And Promise Of Neuroscience, Stephen J. Morse

All Faculty Scholarship

This article is based on the author’s Barrock Lecture in Criminal Law presented at the Marquette University Law School. The central thesis is that the folk psychology that underpins criminal responsibility is correct and that our commonsense understanding of agency and responsibility and the legitimacy of criminal justice generally are not imperiled by contemporary discoveries in the various sciences, including neuroscience and genetics. These sciences will not revolutionize criminal law, at least not anytime soon, and at most they may make modest contributions to legal doctrine, practice, and policy. Until there are conceptual or scientific breakthroughs, this is my story …

Neuroscience, Free Will, And Criminal Responsibility, Stephen J. Morse Jan 2015

Neuroscience, Free Will, And Criminal Responsibility, Stephen J. Morse

All Faculty Scholarship

This chapter argues that the folk-psychological model of the person and responsibility is not challenged by determinism in general or by neurodeterminism in particular. Until science conclusively demonstrates that human beings cannot be guided by reasons and that mental states play no role in explaining behavior, the folk-psychological model of responsibility is justified. This chapter discusses the motivations to turn to science to solve the hard normative problems the law addresses, as well as the law's psychology and its concepts of the person and responsibility. Then it considers the general relation of neuroscience to law, which I characterize as the …

A Good Enough Reason: Addiction, Agency And Criminal Responsibility, Stephen J. Morse Jan 2013

A Good Enough Reason: Addiction, Agency And Criminal Responsibility, Stephen J. Morse

All Faculty Scholarship

The article begins by contrasting medical and moral views of addiction and how such views influence responsibility and policy analysis. It suggests that since addiction always involves action and action can always be morally evaluated, we must independently decide whether addicts do not meet responsibility criteria rather than begging the question and deciding by the label of ‘disease’ or ‘moral weakness’. It then turns to the criteria for criminal responsibility and shows that the criteria for criminal responsibility, like the criteria for addiction, are all folk psychological. Therefore, any scientific information about addiction must be ‘translated’ into the law’s folk …

Genetics And Criminal Responsibility, Stephen J. Morse Jul 2011

Genetics And Criminal Responsibility, Stephen J. Morse

All Faculty Scholarship

Some believe that genetics threatens privacy and autonomy and will eviscerate the concept of human nature. Despite the astonishing research advances, however, none of these dire predictions and no radical transformation of the law have occurred.

Holistic Culpability, Kimberly Kessler Ferzan Jan 2007

Holistic Culpability, Kimberly Kessler Ferzan

All Faculty Scholarship

There are two competing conceptions of mens rea. The first conception is descriptive. We look to a person's mental state to determine if the mental state element is satisfied. This is a question of fact. Alternatively, there is the normative conception of mens rea. This is the question of whether the defendant is blameworthy. The term, mens rea, or "culpability," can therefore refer to the descriptive usage (did the defendant have the requisite mental state, i.e, purpose or knowledge?) or to the normative usage (is the defendant blameworthy, wicked, indifferent?). The tension between descriptive and normative terminology was first identified …

The Uneasy Entente Between Legal Insanity And Mens Rea: Beyond Clark V. Arizona, Stephen J. Morse, Morris B. Hoffman Jan 2007

The Uneasy Entente Between Legal Insanity And Mens Rea: Beyond Clark V. Arizona, Stephen J. Morse, Morris B. Hoffman

All Faculty Scholarship

There is uneasy tension in the criminal law between the doctrines of mens rea and the defense of legal insanity. Last term, the Supreme Court addressed both these issues, but failed to clarify the relation between them. Using a wide range of interdisciplinary materials, this article discusses the broad doctrinal, theoretical, and normative issues concerning responsibility that arise in this context. We clarify the meaning of mental disorder, mens rea and legal insanity, the justification for and the relation between the latter two, and the relation among all three. Next we consider the reasoning in Clark, and for the most …

Imputed Criminal Liability, Paul H. Robinson Jan 1984

Imputed Criminal Liability, Paul H. Robinson

All Faculty Scholarship

Typically, the set of elements defining a crime comprise what may be called the paradigm of liability for that offense: An actor is criminally liable if and only if the state proves all these elements. The paradigm of an offense, however, does not always determine criminal liability. Even where all the elements of the paradigm are proven, rules and doctrines create exceptions that affect criminal liability. Some exceptions, such as insanity, duress, and law enforcement authority, can exculpate an actor even though his conduct and state of mind satisfy the paradigm for the offense charged. Such exculpating exceptions are grouped …
