It is common ground, as between legal positivists and their critics, that the criminal law ought to be codified in such a way that it can be relied on directly by citizens. I shall criticize this “guidance view” of the criminal law, through analyzing the ambitious attempt of Paul Robinson to devise a criminal code wholly shaped by that view. While there are reasons to favor a legislated criminal code over judge-made criminal law, there is no reason to think that such a code must be capable of guiding laypeople directly. Further, there may be reasons to accept limited judicial discretion to reinterpret the scope of the criminal law to meet unanticipated circumstances. Positivists’ preference (inspired by H.L.A Hart) for legislation coupled with limited judicial discretion is not, and should not, be supported by the (wrongly) supposed need to meet the requirements of the “guidance view.”
