Criminal law has developed to prohibit new forms of intrusion on the autonomy and mental processes of others. Examples include modern understandings of fraud, extortion, and bribery, which pivot on the concepts of deception, coercion, and improper influence. Sometimes core offenses develop to include similar concepts, such as when reforms in the law of sexual assault make consent almost exclusively material. Many of these projects are laudable. But progressive programs in substantive criminal law can raise difficult problems of culpability. Modern iterations of criminal offenses often draw lines using concepts involving relative mental states among persons whose conduct is embedded within socially welcome activities. With such offenses, legal institutions struggle in borderline cases to locate sufficient fault to satisfy the demands of justification for punishment. This Article demonstrates this problem through exploration of the law of each of these offenses in modern form.
To address the problem, the Article turns to criminal law theory, finding a connection between culpability and the principle of notice in criminal law. Rather than its absence serving to exculpate, notice can profitably be understood to inculpate. To manage the problem of culpability in modern crime, the Article concludes, legal institutions should attend more explicitly — in both criminalization and adjudication — to the questions whether the actor was aware of the normative wrongfulness of her conduct and, if not, whether punishment is justified on a negligence level of fault. This orientation is especially advisable when further expansive moves in American criminal justice are now difficult to justify
