 Legal regulation takes a number of distinct legal forms to which legislators and judges pay strict attention. The state might impose, on the same conduct, one or more of the following forms of regulation: criminal penalties, a civil fine, an administrative fine, a tax, a license, or a private civil action. Different forms of regulation clearly have different expressive features. But typically the legal profession and the public may think the different forms have different behavioral consequences. These different behavioral consequences may suggest that the law, or at least the form the legal regulation takes, provides distinctive reasons for action.
